.TH "GEMFILE" "5" "December 2021" "" ""
.
.SH "NAME"
\fBGemfile\fR \- A format for describing gem dependencies for Ruby programs
.
.SH "SYNOPSIS"
A \fBGemfile\fR describes the gem dependencies required to execute associated Ruby code\.
.
.P
Place the \fBGemfile\fR in the root of the directory containing the associated code\. For instance, in a Rails application, place the \fBGemfile\fR in the same directory as the \fBRakefile\fR\.
.
.SH "SYNTAX"
A \fBGemfile\fR is evaluated as Ruby code, in a context which makes available a number of methods used to describe the gem requirements\.
.
.SH "GLOBAL SOURCES"
At the top of the \fBGemfile\fR, add a line for the \fBRubygems\fR source that contains the gems listed in the \fBGemfile\fR\.
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
.
.fi
.
.IP "" 0
.
.P
It is possible, but not recommended as of Bundler 1\.7, to add multiple global \fBsource\fR lines\. Each of these \fBsource\fRs \fBMUST\fR be a valid Rubygems repository\.
.
.P
Sources are checked for gems following the heuristics described in \fISOURCE PRIORITY\fR\. If a gem is found in more than one global source, Bundler will print a warning after installing the gem indicating which source was used, and listing the other sources where the gem is available\. A specific source can be selected for gems that need to use a non\-standard repository, suppressing this warning, by using the \fI\fB:source\fR option\fR or a \fI\fBsource\fR block\fR\.
.
.SS "CREDENTIALS"
Some gem sources require a username and password\. Use bundle config(1) \fIbundle\-config\.1\.html\fR to set the username and password for any of the sources that need it\. The command must be run once on each computer that will install the Gemfile, but this keeps the credentials from being stored in plain text in version control\.
.
.IP "" 4
.
.nf
bundle config gems\.example\.com user:password
.
.fi
.
.IP "" 0
.
.P
For some sources, like a company Gemfury account, it may be easier to include the credentials in the Gemfile as part of the source URL\.
.
.IP "" 4
.
.nf
source "https://user:password@gems\.example\.com"
.
.fi
.
.IP "" 0
.
.P
Credentials in the source URL will take precedence over credentials set using \fBconfig\fR\.
.
.SH "RUBY"
If your application requires a specific Ruby version or engine, specify your requirements using the \fBruby\fR method, with the following arguments\. All parameters are \fBOPTIONAL\fR unless otherwise specified\.
.
.SS "VERSION (required)"
The version of Ruby that your application requires\. If your application requires an alternate Ruby engine, such as JRuby, Rubinius or TruffleRuby, this should be the Ruby version that the engine is compatible with\.
.
.IP "" 4
.
.nf
ruby "1\.9\.3"
.
.fi
.
.IP "" 0
.
.SS "ENGINE"
Each application \fImay\fR specify a Ruby engine\. If an engine is specified, an engine version \fImust\fR also be specified\.
.
.P
What exactly is an Engine? \- A Ruby engine is an implementation of the Ruby language\.
.
.IP "\(bu" 4
For background: the reference or original implementation of the Ruby programming language is called Matz\'s Ruby Interpreter \fIhttps://en\.wikipedia\.org/wiki/Ruby_MRI\fR, or MRI for short\. This is named after Ruby creator Yukihiro Matsumoto, also known as Matz\. MRI is also known as CRuby, because it is written in C\. MRI is the most widely used Ruby engine\.
.
.IP "\(bu" 4
Other implementations \fIhttps://www\.ruby\-lang\.org/en/about/\fR of Ruby exist\. Some of the more well\-known implementations include Rubinius \fIhttps://rubinius\.com/\fR, and JRuby \fIhttp://jruby\.org/\fR\. Rubinius is an alternative implementation of Ruby written in Ruby\. JRuby is an implementation of Ruby on the JVM, short for Java Virtual Machine\.
.
.IP "" 0
.
.SS "ENGINE VERSION"
Each application \fImay\fR specify a Ruby engine version\. If an engine version is specified, an engine \fImust\fR also be specified\. If the engine is "ruby" the engine version specified \fImust\fR match the Ruby version\.
.
.IP "" 4

.
.IP "" 4
.
.nf
ruby "2\.0\.0", :patchlevel => "247"
.
.fi
.
.IP "" 0
.
.SH "GEMS"
Specify gem requirements using the \fBgem\fR method, with the following arguments\. All parameters are \fBOPTIONAL\fR unless otherwise specified\.
.
.SS "NAME (required)"
For each gem requirement, list a single \fIgem\fR line\.
.
.IP "" 4
.
.nf
gem "nokogiri"
.
.fi
.
.IP "" 0
.
.SS "VERSION"
Each \fIgem\fR \fBMAY\fR have one or more version specifiers\.
.

gem "RedCloth", ">= 4\.1\.0", "< 4\.2\.0"
.
.fi
.
.IP "" 0
.
.SS "REQUIRE AS"
Each \fIgem\fR \fBMAY\fR specify files that should be used when autorequiring via \fBBundler\.require\fR\. You may pass an array with multiple files or \fBtrue\fR if the file you want \fBrequired\fR has the same name as \fIgem\fR or \fBfalse\fR to prevent any file from being autorequired\.
.
.IP "" 4

gem "webmock", :require => false
gem "byebug", :require => true

The argument defaults to the name of the gem\. For example, these are identical:
.
.IP "" 4
.
.nf
gem "nokogiri"
gem "nokogiri", :require => "nokogiri"
gem "nokogiri", :require => true
.
.fi
.
.IP "" 0
.
.SS "GROUPS"
Each \fIgem\fR \fBMAY\fR specify membership in one or more groups\. Any \fIgem\fR that does not specify membership in any group is placed in the \fBdefault\fR group\.
.
.IP "" 4
.
.nf
gem "rspec", :group => :test
gem "wirble", :groups => [:development, :test]
.
.fi
.
.IP "" 0
.
.P
The Bundler runtime allows its two main methods, \fBBundler\.setup\fR and \fBBundler\.require\fR, to limit their impact to particular groups\.
.
.IP "" 4
.
.nf
# setup adds gems to Ruby\'s load path
Bundler\.setup # defaults to all groups
require "bundler/setup" # same as Bundler\.setup
Bundler\.setup(:default) # only set up the _default_ group
Bundler\.setup(:test) # only set up the _test_ group (but `not` _default_)
Bundler\.setup(:default, :test) # set up the _default_ and _test_ groups, but no others
# require requires all of the gems in the specified groups
Bundler\.require # defaults to the _default_ group
Bundler\.require(:default) # identical
Bundler\.require(:default, :test) # requires the _default_ and _test_ groups
Bundler\.require(:test) # requires the _test_ group
.
.fi
.
.IP "" 0
.
.P
The Bundler CLI allows you to specify a list of groups whose gems \fBbundle install\fR should not install with the \fBwithout\fR configuration\.
.
.P
To specify multiple groups to ignore, specify a list of groups separated by spaces\.
.
.IP "" 4
.
.nf
bundle config set \-\-local without test
bundle config set \-\-local without development test
.
.fi
.
.IP "" 0
.
.P
Also, calling \fBBundler\.setup\fR with no parameters, or calling \fBrequire "bundler/setup"\fR will setup all groups except for the ones you excluded via \fB\-\-without\fR (since they are not available)\.
.
.P
Note that on \fBbundle install\fR, bundler downloads and evaluates all gems, in order to create a single canonical list of all of the required gems and their dependencies\. This means that you cannot list different versions of the same gems in different groups\. For more details, see Understanding Bundler \fIhttps://bundler\.io/rationale\.html\fR\.
.
.SS "PLATFORMS"
If a gem should only be used in a particular platform or set of platforms, you can specify them\. Platforms are essentially identical to groups, except that you do not need to use the \fB\-\-without\fR install\-time flag to exclude groups of gems for other platforms\.
.
.P
There are a number of \fBGemfile\fR platforms:
.
.TP
\fBruby\fR
C Ruby (MRI), Rubinius or TruffleRuby, but \fBNOT\fR Windows
.
.TP
\fBmri\fR
Same as \fIruby\fR, but only C Ruby (MRI)
.
.TP
\fBmingw\fR
Windows 32 bit \'mingw32\' platform (aka RubyInstaller)
.
.TP
\fBx64_mingw\fR
Windows 64 bit \'mingw32\' platform (aka RubyInstaller x64)
.
.TP
\fBrbx\fR
Rubinius
.
.TP
\fBjruby\fR
JRuby
.
.TP
\fBtruffleruby\fR
TruffleRuby
.
.TP
\fBmswin\fR
Windows
.
.P
You can restrict further by platform and version for all platforms \fIexcept\fR for \fBrbx\fR, \fBjruby\fR, \fBtruffleruby\fR and \fBmswin\fR\.
.
.P
To specify a version in addition to a platform, append the version number without the delimiter to the platform\. For example, to specify that a gem should only be used on platforms with Ruby 2\.3, use:
.
.IP "" 4
.
.nf
ruby_23
.
.fi
.
.IP "" 0
.
.P
The full list of platforms and supported versions includes:
.
.TP
\fBruby\fR
1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6
.
.TP
\fBmri\fR
1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6
.
.TP
\fBmingw\fR
1\.8, 1\.9, 2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6
.
.TP
\fBx64_mingw\fR
2\.0, 2\.1, 2\.2, 2\.3, 2\.4, 2\.5, 2\.6
.
.P
As with groups, you can specify one or more platforms:
.
.IP "" 4
.
.nf
gem "weakling", :platforms => :jruby
gem "ruby\-debug", :platforms => :mri_18
gem "nokogiri", :platforms => [:mri_18, :jruby]
.
.fi
.
.IP "" 0
.
.P
All operations involving groups (\fBbundle install\fR \fIbundle\-install\.1\.html\fR, \fBBundler\.setup\fR, \fBBundler\.require\fR) behave exactly the same as if any groups not matching the current platform were explicitly excluded\.
.
.SS "SOURCE"
You can select an alternate Rubygems repository for a gem using the \':source\' option\.
.
.IP "" 4
.
.nf
gem "some_internal_gem", :source => "https://gems\.example\.com"
.
.fi
.
.IP "" 0
.
.P
This forces the gem to be loaded from this source and ignores any global sources declared at the top level of the file\. If the gem does not exist in this source, it will not be installed\.
.
.P
Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on global sources using the ordering described in \fISOURCE PRIORITY\fR\.
.
.P
Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in \fIGLOBAL SOURCES (#source)\fR\.
.
.P
Using the \fB:source\fR option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources\.
.
.SS "GIT"
If necessary, you can specify that a gem is located at a particular git repository using the \fB:git\fR parameter\. The repository can be accessed via several protocols:
.
.TP
\fBHTTP(S)\fR
gem "rails", :git => "https://github\.com/rails/rails\.git"
.
.TP
\fBSSH\fR
gem "rails", :git => "git@github\.com:rails/rails\.git"
.
.TP
\fBgit\fR
gem "rails", :git => "git://github\.com/rails/rails\.git"
.
.P
If using SSH, the user that you use to run \fBbundle install\fR \fBMUST\fR have the appropriate keys available in their \fB$HOME/\.ssh\fR\.
.
.P
\fBNOTE\fR: \fBhttp://\fR and \fBgit://\fR URLs should be avoided if at all possible\. These protocols are unauthenticated, so a man\-in\-the\-middle attacker can deliver malicious code and compromise your system\. HTTPS and SSH are strongly preferred\.
.
.P
The \fBgroup\fR, \fBplatforms\fR, and \fBrequire\fR options are available and behave exactly the same as they would for a normal gem\.
.
.P
A git repository \fBSHOULD\fR have at least one file, at the root of the directory containing the gem, with the extension \fB\.gemspec\fR\. This file \fBMUST\fR contain a valid gem specification, as expected by the \fBgem build\fR command\.
.
.P
If a git repository does not have a \fB\.gemspec\fR, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions\. As a result, it may fail to properly integrate into your application\.
.
.P
If a git repository does have a \fB\.gemspec\fR for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the \fB\.gemspec\fR specifies a version matching the version specifier\. If not, bundler will print a warning\.
.
.IP "" 4
.
.nf
gem "rails", "2\.3\.8", :git => "https://github\.com/rails/rails\.git"
# bundle install will fail, because the \.gemspec in the rails
# repository\'s master branch specifies version 3\.0\.0
.
.fi
.
.IP "" 0
.
.P
If a git repository does \fBnot\fR have a \fB\.gemspec\fR for the gem you attached it to, a version specifier \fBMUST\fR be provided\. Bundler will use this version in the simple \fB\.gemspec\fR it creates\.
.
.P
Git repositories support a number of additional options\.
.
.TP
\fBbranch\fR, \fBtag\fR, and \fBref\fR
You \fBMUST\fR only specify at most one of these options\. The default is \fB:branch => "master"\fR\. For example:
.
.IP
gem "rails", :git => "https://github\.com/rails/rails\.git", :branch => "5\-0\-stable"
.
.IP
gem "rails", :git => "https://github\.com/rails/rails\.git", :tag => "v5\.0\.0"
.
.IP
gem "rails", :git => "https://github\.com/rails/rails\.git", :ref => "4aded"
.
.TP
\fBsubmodules\fR
For reference, a git submodule \fIhttps://git\-scm\.com/book/en/v2/Git\-Tools\-Submodules\fR lets you have another git repository within a subfolder of your repository\. Specify \fB:submodules => true\fR to cause bundler to expand any submodules included in the git repository
.
.P
If a git repository contains multiple \fB\.gemspecs\fR, each \fB\.gemspec\fR represents a gem located at the same place in the file system as the \fB\.gemspec\fR\.
.
.IP "" 4
.
.nf
|~rails [git root]
| |\-rails\.gemspec [rails gem located here]
|~actionpack
| |\-actionpack\.gemspec [actionpack gem located here]
|~activesupport
| |\-activesupport\.gemspec [activesupport gem located here]
|\.\.\.
.
.fi
.
.IP "" 0
.
.P
To install a gem located in a git repository, bundler changes to the directory containing the gemspec, runs \fBgem build name\.gemspec\fR and then installs the resulting gem\. The \fBgem build\fR command, which comes standard with Rubygems, evaluates the \fB\.gemspec\fR in the context of the directory in which it is located\.
.
.SS "GIT SOURCE"
A custom git source can be defined via the \fBgit_source\fR method\. Provide the source\'s name as an argument, and a block which receives a single argument and interpolates it into a string to return the full repo address:
.
.IP "" 4
.
.nf
git_source(:stash){ |repo_name| "https://stash\.corp\.acme\.pl/#{repo_name}\.git" }
gem \'rails\', :stash => \'forks/rails\'
.
.fi
.
.IP "" 0
.
.P
In addition, if you wish to choose a specific branch:
.
.IP "" 4
.
.nf
gem "rails", :stash => "forks/rails", :branch => "branch_name"
.
.fi
.
.IP "" 0
.
.SS "GITHUB"
\fBNOTE\fR: This shorthand should be avoided until Bundler 2\.0, since it currently expands to an insecure \fBgit://\fR URL\. This allows a man\-in\-the\-middle attacker to compromise your system\.
.
.P
If the git repository you want to use is hosted on GitHub and is public, you can use the :github shorthand to specify the github username and repository name (without the trailing "\.git"), separated by a slash\. If both the username and repository name are the same, you can omit one\.
.
.IP "" 4
.
.nf
gem "rails", :github => "rails/rails"
gem "rails", :github => "rails"
.

.
.IP "" 4
.
.nf
gem "rails", :git => "git://github\.com/rails/rails\.git"
.
.fi
.
.IP "" 0
.
.P
Since the \fBgithub\fR method is a specialization of \fBgit_source\fR, it accepts a \fB:branch\fR named argument\.
.
.P
You can also directly pass a pull request URL:
.
.IP "" 4
.
.nf
gem "rails", :github => "https://github\.com/rails/rails/pull/43753"
.
.fi
.

.
.fi
.
.IP "" 0

.SS "GIST"
If the git repository you want to use is hosted as a Github Gist and is public, you can use the :gist shorthand to specify the gist identifier (without the trailing "\.git")\.
.
.IP "" 4

.nf
gem "the_hatch", :gist => "4815162342"

.SS "BITBUCKET"
If the git repository you want to use is hosted on Bitbucket and is public, you can use the :bitbucket shorthand to specify the bitbucket username and repository name (without the trailing "\.git"), separated by a slash\. If both the username and repository name are the same, you can omit one\.

Since the \fBbitbucket\fR method is a specialization of \fBgit_source\fR, it accepts a \fB:branch\fR named argument\.
.
.SS "PATH"
You can specify that a gem is located in a particular location on the file system\. Relative paths are resolved relative to the directory containing the \fBGemfile\fR\.
.
.P
Similar to the semantics of the \fB:git\fR option, the \fB:path\fR option requires that the directory in question either contains a \fB\.gemspec\fR for the gem, or that you specify an explicit version that bundler should use\.
.
.P
Unlike \fB:git\fR, bundler does not compile C extensions for gems specified as paths\.
.
.IP "" 4

.
.IP "" 0

.SH "BLOCK FORM OF SOURCE, GIT, PATH, GROUP and PLATFORMS"
The \fB:source\fR, \fB:git\fR, \fB:path\fR, \fB:group\fR, and \fB:platforms\fR options may be applied to a group of gems by using block form\.
.
.IP "" 4
.

end
.
.fi
.
.IP "" 0
.
.P
In the case of the group block form the :optional option can be given to prevent a group from being installed unless listed in the \fB\-\-with\fR option given to the \fBbundle install\fR command\.
.
.P
In the case of the \fBgit\fR block form, the \fB:ref\fR, \fB:branch\fR, \fB:tag\fR, and \fB:submodules\fR options may be passed to the \fBgit\fR method, and all gems in the block will inherit those options\.
.
.P
The presence of a \fBsource\fR block in a Gemfile also makes that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when defining source blocks, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources, either via source blocks or \fB:source\fR directives on individual gems\.
.
.SH "INSTALL_IF"
The \fBinstall_if\fR method allows gems to be installed based on a proc or lambda\. This is especially useful for optional gems that can only be used if certain software is installed or some other conditions are met\.
.
.IP "" 4

.IP "" 0
.
.SH "GEMSPEC"
The \fB\.gemspec\fR \fIhttp://guides\.rubygems\.org/specification\-reference/\fR file is where you provide metadata about your gem to Rubygems\. Some required Gemspec attributes include the name, description, and homepage of your gem\. This is also where you specify the dependencies your gem needs to run\.
.
.P
If you wish to use Bundler to help install dependencies for a gem while it is being developed, use the \fBgemspec\fR method to pull in the dependencies listed in the \fB\.gemspec\fR file\.
.
.P
The \fBgemspec\fR method adds any runtime dependencies as gem requirements in the default group\. It also adds development dependencies as gem requirements in the \fBdevelopment\fR group\. Finally, it adds a gem requirement on your project (\fB:path => \'\.\'\fR)\. In conjunction with \fBBundler\.setup\fR, this allows you to require project files in your test code as you would if the project were installed as a gem; you need not manipulate the load path manually or require project files via relative paths\.
.
.P
The \fBgemspec\fR method supports optional \fB:path\fR, \fB:glob\fR, \fB:name\fR, and \fB:development_group\fR options, which control where bundler looks for the \fB\.gemspec\fR, the glob it uses to look for the gemspec (defaults to: "{,\fI,\fR/*}\.gemspec"), what named \fB\.gemspec\fR it uses (if more than one is present), and which group development dependencies are included in\.
.
.P
When a \fBgemspec\fR dependency encounters version conflicts during resolution, the local version under development will always be selected \-\- even if there are remote versions that better match other requirements for the \fBgemspec\fR gem\.
.
.SH "SOURCE PRIORITY"
When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order:
.
.IP "1." 4
The source explicitly attached to the gem (using \fB:source\fR, \fB:path\fR, or \fB:git\fR)
.
.IP "2." 4
For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent\. This results in bundler prioritizing the ActiveSupport gem from the Rails git repository over ones from \fBrubygems\.org\fR
.
.IP "3." 4
The sources specified via global \fBsource\fR lines, searching each source in your \fBGemfile\fR from last added to first added\.

.
.fi
.
.IP "" 0
.
.P
As you can see, even though you have two gems in the Gemfile(5), your application needs 26 different gems in order to run\. Bundler remembers the exact versions it installed in \fBGemfile\.lock\fR\. The next time you run bundle install(1) \fIbundle\-install\.1\.html\fR, bundler skips the dependency resolution and installs the same gems as it installed last time\.
.
.P
After checking in the \fBGemfile\.lock\fR into version control and cloning it on another machine, running bundle install(1) \fIbundle\-install\.1\.html\fR will \fIstill\fR install the gems that you installed last time\. You don\'t need to worry that a new release of \fBerubis\fR or \fBmail\fR changes the gems you use\.
.
.P
However, from time to time, you might want to update the gems you are using to the newest versions that still match the gems in your Gemfile(5)\.
.
.P
To do this, run \fBbundle update \-\-all\fR, which will ignore the \fBGemfile\.lock\fR, and resolve all the dependencies again\. Keep in mind that this process can result in a significantly different set of the 25 gems, based on the requirements of new gems that the gem authors released since the last time you ran \fBbundle update \-\-all\fR\.
.
.SH "UPDATING A LIST OF GEMS"
Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\.
.
.P
For instance, in the scenario above, imagine that \fBnokogiri\fR releases version \fB1\.4\.4\fR, and you want to update it \fIwithout\fR updating Rails and all of its dependencies\. To do this, run \fBbundle update nokogiri\fR\.
.
.P
Bundler will update \fBnokogiri\fR and any of its dependencies, but leave alone Rails and its dependencies\.
.
.SH "OVERLAPPING DEPENDENCIES"
Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same second\-level dependency\. For instance, consider the case of \fBthin\fR and \fBrack\-perftools\-profiler\fR\.
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
gem "thin"
gem "rack\-perftools\-profiler"
.
.fi
.
.IP "" 0
.
.P
The \fBthin\fR gem depends on \fBrack >= 1\.0\fR, while \fBrack\-perftools\-profiler\fR depends on \fBrack ~> 1\.0\fR\. If you run bundle install, you get:
.
.IP "" 4
.
.nf
Fetching source index for https://rubygems\.org/
Installing daemons (1\.1\.0)
Installing eventmachine (0\.12\.10) with native extensions
Installing open4 (1\.0\.1)
Installing perftools\.rb (0\.4\.7) with native extensions
Installing rack (1\.2\.1)
Installing rack\-perftools_profiler (0\.0\.2)
Installing thin (1\.2\.7) with native extensions
Using bundler (1\.0\.0\.rc\.3)
.
.fi
.
.IP "" 0
.
.P
In this case, the two gems have their own set of dependencies, but they share \fBrack\fR in common\. If you run \fBbundle update thin\fR, bundler will update \fBdaemons\fR, \fBeventmachine\fR and \fBrack\fR, which are dependencies of \fBthin\fR, but not \fBopen4\fR or \fBperftools\.rb\fR, which are dependencies of \fBrack\-perftools_profiler\fR\. Note that \fBbundle update thin\fR will update \fBrack\fR even though it\'s \fIalso\fR a dependency of \fBrack\-perftools_profiler\fR\.
.
.P
In short, by default, when you update a gem using \fBbundle update\fR, bundler will update all dependencies of that gem, including those that are also dependencies of another gem\.
.
.P
To prevent updating indirect dependencies, prior to version 1\.14 the only option was the \fBCONSERVATIVE UPDATING\fR behavior in bundle install(1) \fIbundle\-install\.1\.html\fR:
.
.P
In this scenario, updating the \fBthin\fR version manually in the Gemfile(5), and then running bundle install(1) \fIbundle\-install\.1\.html\fR will only update \fBdaemons\fR and \fBeventmachine\fR, but not \fBrack\fR\. For more information, see the \fBCONSERVATIVE UPDATING\fR section of bundle install(1) \fIbundle\-install\.1\.html\fR\.
.
.P
Starting with 1\.14, specifying the \fB\-\-conservative\fR option will also prevent indirect dependencies from being updated\.
.
.SH "PATCH LEVEL OPTIONS"
Version 1\.14 introduced 4 patch\-level options that will influence how gem versions are resolved\. One of the following options can be used: \fB\-\-patch\fR, \fB\-\-minor\fR or \fB\-\-major\fR\. \fB\-\-strict\fR can be added to further influence resolution\.
.
.TP
\fB\-\-patch\fR
Prefer updating only to next patch version\.
.
.TP
\fB\-\-minor\fR
Prefer updating only to next minor version\.
.
.TP
\fB\-\-major\fR
Prefer updating to next major version (default)\.
.
.TP
\fB\-\-strict\fR
Do not allow any gem to be updated past latest \fB\-\-patch\fR | \fB\-\-minor\fR | \fB\-\-major\fR\.
.
.P
When Bundler is resolving what versions to use to satisfy declared requirements in the Gemfile or in parent gems, it looks up all available versions, filters out any versions that don\'t satisfy the requirement, and then, by default, sorts them from newest to oldest, considering them in that order\.
.
.P
Providing one of the patch level options (e\.g\. \fB\-\-patch\fR) changes the sort order of the satisfying versions, causing Bundler to consider the latest \fB\-\-patch\fR or \fB\-\-minor\fR version available before other versions\. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph\.
.
.P
For example, if gem \'foo\' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
.
.P
If the \fB\-\-patch\fR option is used, the order of preference will change to "1\.0\.4, 1\.0\.3, 1\.0\.2, 1\.1\.1, 1\.1\.0, 2\.0\.0"\.
.
.P
If the \fB\-\-minor\fR option is used, the order of preference will change to "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2, 2\.0\.0"\.
.
.P
Combining the \fB\-\-strict\fR option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far\.
.
.P
To continue the previous example, if both \fB\-\-patch\fR and \fB\-\-strict\fR options are used, the available versions for resolution would be "1\.0\.4, 1\.0\.3, 1\.0\.2"\. If \fB\-\-minor\fR and \fB\-\-strict\fR are used, it would be "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
.
.P
Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available\. If the gem requirement for \fBfoo\fR in the Gemfile is \'~> 1\.0\', that will accomplish the same thing as providing the \fB\-\-minor\fR and \fB\-\-strict\fR options\.

.P
In case 1, bar is upgraded to 2\.1\.1, a minor version increase, because the dependency from foo 1\.4\.5 required it\.
.
.P
In case 2, only foo is requested to be unlocked, but bar is also allowed to move because it\'s not a declared dependency in the Gemfile\.
.
.P
In case 3, bar goes up a whole major release, because a minor increase is preferred now for foo, and when it goes to 1\.5\.1, it requires 3\.0\.0 of bar\.
.
.P
In case 4, foo is preferred up to a minor version, but 1\.5\.1 won\'t work because the \-\-strict flag removes bar 3\.0\.0 from consideration since it\'s a major increment\.
.
.P
In case 5, both foo and bar have any minor or major increments removed from consideration because of the \-\-strict flag, so the most they can move is up to 1\.4\.4 and 2\.0\.4\.

.Sh DESCRIPTION
Ruby is an interpreted scripting language for quick and easy
object-oriented programming. It has many features to process text
files and to do system management tasks (like in Perl). It is simple,
straight-forward, and extensible.
.Pp
If you want a language for easy object-oriented programming, or you
don't like the Perl ugliness, or you do like the concept of LISP, but
don't like too many parentheses, Ruby might be your language of
choice.
.Sh FEATURES
Ruby's features are as follows:
.Bl -tag -width 6n
.It Sy "Interpretive"
Ruby is an interpreted language, so you don't have to recompile
programs written in Ruby to execute them.
.Pp
.It Sy "Variables have no type (dynamic typing)"
Variables in Ruby can contain data of any type. You don't have to
worry about variable typing. Consequently, it has a weaker compile
time check.
.Pp
.It Sy "No declaration needed"
You can use variables in your Ruby programs without any declarations.
Variable names denote their scope - global, class, instance, or local.
.Pp
.It Sy "Simple syntax"
Ruby has a simple syntax influenced slightly from Eiffel.
.Pp
.It Sy "No user-level memory management"
Ruby has automatic memory management. Objects no longer referenced
from anywhere are automatically collected by the garbage collector
built into the interpreter.
.Pp
.It Sy "Everything is an object"
Ruby is a purely object-oriented language, and was so since its
creation. Even such basic data as integers are seen as objects.
.Pp
.It Sy "Class, inheritance, and methods"
Being an object-oriented language, Ruby naturally has basic
features like classes, inheritance, and methods.
.Pp
.It Sy "Singleton methods"
Ruby has the ability to define methods for certain objects. For
example, you can define a press-button action for certain widget by
defining a singleton method for the button. Or, you can make up your
own prototype based object system using singleton methods, if you want
to.
.Pp
.It Sy "Mix-in by modules"
Ruby intentionally does not have the multiple inheritance as it is a
source of confusion. Instead, Ruby has the ability to share
implementations across the inheritance tree. This is often called a
.Sq Mix-in .
.Pp
.It Sy "Iterators"
Ruby has iterators for loop abstraction.
.Pp
.It Sy "Closures"
In Ruby, you can objectify the procedure.
.Pp
.It Sy "Text processing and regular expressions"
Ruby has a bunch of text processing features like in Perl.
.Pp
.It Sy "M17N, character set independent"
Ruby supports multilingualized programming. Easy to process texts
written in many different natural languages and encoded in many
different character encodings, without dependence on Unicode.
.Pp
.It Sy "Bignums"
With built-in bignums, you can for example calculate factorial(400).
.Pp
.It Sy "Reflection and domain specific languages"
Class is also an instance of the Class class. Definition of classes and methods
is an expression just as 1+1 is. So your programs can even write and modify programs.
Thus you can write your application in your own programming language on top of Ruby.
.Pp
.It Sy "Exception handling"
As in Java(tm).
.Pp
.It Sy "Direct access to the OS"
Ruby can use most
.Ux
system calls, often used in system programming.
.Pp
.It Sy "Dynamic loading"
On most
.Ux
systems, you can load object files into the Ruby interpreter
on-the-fly.
.It Sy "Rich libraries"
In addition to the
.Dq builtin libraries
and
.Dq standard libraries
that are bundled with Ruby, a vast amount of third-party libraries
.Pq Dq gems
are available via the package management system called
.Sq RubyGems ,
namely the
.Xr gem 1
command. Visit RubyGems.org
.Pq Lk https://rubygems.org/
to find the gems you need, and explore GitHub
.Pq Lk https://github.com/
to see how they are being developed and used.
.El
.Pp
.Sh OPTIONS
The Ruby interpreter accepts the following command-line options (switches).
They are quite similar to those of
.Xr perl 1 .
.Bl -tag -width "1234567890123" -compact
.Pp
.It Fl -copyright
Prints the copyright notice, and quits immediately without running any
script.
.Pp
.It Fl -version
Prints the version of the Ruby interpreter, and quits immediately without
running any script.
.Pp
.It Fl 0 Ns Op Ar octal
(The digit
.Dq zero . )
Specifies the input record separator
.Pf ( Li "$/" )
as an octal number. If no digit is given, the null character is taken
as the separator. Other switches may follow the digits.
.Fl 00
turns Ruby into paragraph mode.
.Fl 0777
makes Ruby read whole file at once as a single string since there is
no legal character with that value.
.Pp
.It Fl C Ar directory
.It Fl X Ar directory
Causes Ruby to switch to the directory.
.Pp
.It Fl E Ar external Ns Op : Ns Ar internal
.It Fl -encoding Ar external Ns Op : Ns Ar internal
Specifies the default value(s) for external encodings and internal encoding. Values should be separated with colon (:).
.Pp
You can omit the one for internal encodings, then the value
.Pf ( Li "Encoding.default_internal" ) will be nil.
.Pp
.It Fl -external-encoding Ns = Ns Ar encoding
.It Fl -internal-encoding Ns = Ns Ar encoding
Specify the default external or internal character encoding
.Pp
.It Fl F Ar pattern
Specifies input field separator
.Pf ( Li "$;" ) .
.Pp
.It Fl I Ar directory
Used to tell Ruby where to load the library scripts. Directory path
will be added to the load-path variable
.Pf ( Li "$:" ) .
.Pp
.It Fl K Ar kcode
Specifies KANJI (Japanese) encoding. The default value for script encodings
.Pf ( Li "__ENCODING__" ) and external encodings ( Li "Encoding.default_external" ) will be the specified one.
.Ar kcode
can be one of
.Bl -hang -offset indent
.It Sy e
EUC-JP
.Pp
.It Sy s
Windows-31J (CP932)
.Pp
.It Sy u
UTF-8
.Pp
.It Sy n
ASCII-8BIT (BINARY)
.El
.Pp
.It Fl S
Makes Ruby use the
.Ev PATH
environment variable to search for script, unless its name begins
with a slash. This is used to emulate
.Li #!
on machines that don't support it, in the following manner:
.Bd -literal -offset indent
#! /usr/local/bin/ruby
# This line makes the next one a comment in Ruby \e
exec /usr/local/bin/ruby -S $0 $*
.Ed
.Pp
On some systems
.Li "$0"
does not always contain the full pathname, so you need the
.Fl S
switch to tell Ruby to search for the script if necessary (to handle embedded
spaces and such). A better construct than
.Li "$*"
would be
.Li ${1+"$@"} ,
but it does not work if the script is being interpreted by
.Xr csh 1 .
.Pp
.It Fl T Ns Op Ar level=1
Turns on taint checks at the specified level (default 1).
.Pp
.It Fl U
Sets the default value for internal encodings
.Pf ( Li "Encoding.default_internal" ) to UTF-8.
.Pp
.It Fl W Ns Op Ar level=2
Turns on verbose mode at the specified level without printing the version
message at the beginning. The level can be;
.Bl -hang -offset indent
.It Sy 0
Verbose mode is "silence". It sets the
.Li "$VERBOSE"
to nil.
.Pp
.It Sy 1
Verbose mode is "medium". It sets the
.Li "$VERBOSE"
to false.
.Pp
.It Sy 2 (default)
Verbose mode is "verbose". It sets the
.Li "$VERBOSE"
to true.
.Fl W Ns
2 is same as
.Fl w
.
.El
.Pp
.It Fl a
Turns on auto-split mode when used with
.Fl n
or
.Fl p .
In auto-split mode, Ruby executes
.Dl $F = $_.split
at beginning of each loop.
.Pp
.It Fl c
Causes Ruby to check the syntax of the script and exit without
executing. If there are no syntax errors, Ruby will print
.Dq Syntax OK
to the standard output.
.Pp
.It Fl d
.It Fl -debug
Turns on debug mode.
.Li "$DEBUG"
will be set to true.
.Pp
.It Fl e Ar command
Specifies script from command-line while telling Ruby not to search
the rest of the arguments for a script file name.
.Pp
.It Fl h
.It Fl -help
Prints a summary of the options.
.Pp
.It Fl i Ar extension
Specifies in-place-edit mode. The extension, if specified, is added
to old file name to make a backup copy. For example:
.Bd -literal -offset indent
% echo matz > /tmp/junk
% cat /tmp/junk
matz
% ruby -p -i.bak -e '$_.upcase!' /tmp/junk
% cat /tmp/junk
MATZ
% cat /tmp/junk.bak
matz
.Ed
.Pp
.It Fl l
(The lowercase letter
.Dq ell . )
Enables automatic line-ending processing, which means to firstly set
.Li "$\e"
to the value of
.Li "$/" ,
and secondly chops every line read using
.Li chomp! .
.Pp
.It Fl n
Causes Ruby to assume the following loop around your script, which
makes it iterate over file name arguments somewhat like
.Nm sed
.Fl n
or
.Nm awk .
.Bd -literal -offset indent
while gets
...
end
.Ed
.Pp
.It Fl p
Acts mostly same as -n switch, but print the value of variable
.Li "$_"
at the each end of the loop. For example:
.Bd -literal -offset indent
% echo matz | ruby -p -e '$_.tr! "a-z", "A-Z"'
MATZ
.Ed
.Pp
.It Fl r Ar library
Causes Ruby to load the library using require. It is useful when using
.Fl n
or
.Fl p .
.Pp
.It Fl s
Enables some switch parsing for switches after script name but before
any file name arguments (or before a
.Fl - ) .
Any switches found there are removed from
.Li ARGV
and set the corresponding variable in the script. For example:
.Bd -literal -offset indent
#! /usr/local/bin/ruby -s
# prints "true" if invoked with `-xyz' switch.
print "true\en" if $xyz
.Ed
.Pp
.It Fl v
Enables verbose mode. Ruby will print its version at the beginning
and set the variable
.Li "$VERBOSE"
to true. Some methods print extra messages if this variable is true.
If this switch is given, and no other switches are present, Ruby quits
after printing its version.
.Pp
.It Fl w
Enables verbose mode without printing version message at the
beginning. It sets the
.Li "$VERBOSE"
variable to true.
.Pp
.It Fl x Ns Op Ar directory
Tells Ruby that the script is embedded in a message. Leading garbage
will be discarded until the first line that starts with
.Dq #!
and contains the string,
.Dq ruby .
Any meaningful switches on that line will be applied. The end of the script
must be specified with either
.Li EOF ,
.Li "^D" ( Li "control-D" ) ,
.Li "^Z" ( Li "control-Z" ) ,
or the reserved word
.Li __END__ .
If the directory name is specified, Ruby will switch to that directory
before executing script.
.Pp
.It Fl y
.It Fl -yydebug
DO NOT USE.
.Pp
Turns on compiler debug mode. Ruby will print a bunch of internal
state messages during compilation. Only specify this switch you are going to
debug the Ruby interpreter.
.Pp
.It Fl -disable- Ns Ar FEATURE
.It Fl -enable- Ns Ar FEATURE
Disables (or enables) the specified
.Ar FEATURE .
.Bl -tag -width "--disable-rubyopt" -compact
.It Fl -disable-gems
.It Fl -enable-gems
Disables (or enables) RubyGems libraries. By default, Ruby will load the latest
version of each installed gem. The
.Li Gem
constant is true if RubyGems is enabled, false if otherwise.
.Pp
.It Fl -disable-rubyopt
.It Fl -enable-rubyopt
Ignores (or considers) the
.Ev RUBYOPT
environment variable. By default, Ruby considers the variable.
.Pp
.It Fl -disable-all
.It Fl -enable-all
Disables (or enables) all features.
.Pp
.El
.Pp
.It Fl -dump Ns = Ns Ar target
Dump some information.
.Pp
Prints the specified target.
.Ar target
can be one of;
.Bl -hang -offset indent
.It Sy version
version description same as
.Fl -version
.It Sy usage
brief usage message same as
.Fl h
.It Sy help
Show long help message same as
.Fl -help
.It Sy syntax
check of syntax same as
.Fl c
.Fl -yydebug
.It Sy yydebug
compiler debug mode, same as
.Fl -yydebug
.Pp
Only specify this switch if you are going to debug the Ruby interpreter.
.It Sy parsetree
.It Sy parsetree_with_comment
AST nodes tree
.Pp
Only specify this switch if you are going to debug the Ruby interpreter.
.It Sy insns
disassembled instructions
.Pp
Only specify this switch if you are going to debug the Ruby interpreter.
.El
.Pp
.It Fl -verbose
Enables verbose mode without printing version message at the
beginning. It sets the
.Li "$VERBOSE"
variable to true.
If this switch is given, and no script arguments (script file or
.Fl e
options) are present, Ruby quits immediately.
.El
.Pp
.Sh ENVIRONMENT
.Bl -tag -width "RUBYSHELL" -compact
.It Ev RUBYLIB
A colon-separated list of directories that are added to Ruby's
library load path
.Pf ( Li "$:" ) . Directories from this environment variable are searched
before the standard load path is searched.
.Pp
e.g.:
.Dl RUBYLIB="$HOME/lib/ruby:$HOME/lib/rubyext"
.Pp
.It Ev RUBYOPT
Additional Ruby options.
.Pp
e.g.
.Dl RUBYOPT="-w -Ke"
.Pp
Note that RUBYOPT can contain only
.Fl d , Fl E , Fl I , Fl K , Fl r , Fl T , Fl U , Fl v , Fl w , Fl W, Fl -debug ,
.Fl -disable- Ns Ar FEATURE
and
.Fl -enable- Ns Ar FEATURE .
.Pp
.It Ev RUBYPATH
A colon-separated list of directories that Ruby searches for
Ruby programs when the
.Fl S
flag is specified. This variable precedes the
.Ev PATH
environment variable.
.Pp
.It Ev RUBYSHELL
The path to the system shell command. This environment variable is
enabled for only mswin32, mingw32, and OS/2 platforms. If this
variable is not defined, Ruby refers to
.Ev COMSPEC .
.Pp
.It Ev PATH
Ruby refers to the
.Ev PATH
environment variable on calling Kernel#system.
.El
.Pp
And Ruby depends on some RubyGems related environment variables unless RubyGems is disabled.
See the help of
.Xr gem 1
as below.
.Bd -literal -offset indent
% gem help
.Ed
.Pp
.Sh GC ENVIRONMENT
The Ruby garbage collector (GC) tracks objects in fixed-sized slots,
but each object may have auxiliary memory allocations handled by the
malloc family of C standard library calls (
.Xr malloc 3 ,
.Xr calloc 3 ,
and
.Xr realloc 3 ) .
In this documentatation, the "heap" refers to the Ruby object heap
of fixed-sized slots, while "malloc" refers to auxiliary
allocations commonly referred to as the "process heap".
Thus there are at least two possible ways to trigger GC:
.Bl -hang -offset indent
.It Sy 1
Reaching the object limit.
.It Sy 2
Reaching the malloc limit.
.Pp
.El
In Ruby 2.1, the generational GC was introduced and the limits are divided
into young and old generations, providing two additional ways to trigger
a GC:
.Bl -hang -offset indent
.It Sy 3
Reaching the old object limit.
.It Sy 4
Reaching the old malloc limit.
.El
.Pp
There are currently 4 possible areas where the GC may be tuned by
the following 11 environment variables:
.Bl -hang -compact -width "RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR"
.It Ev RUBY_GC_HEAP_INIT_SLOTS
Initial allocation slots. Introduced in Ruby 2.1, default: 10000.
.Pp
.It Ev RUBY_GC_HEAP_FREE_SLOTS
Prepare at least this amount of slots after GC.
Allocate this number slots if there are not enough slots.
Introduced in Ruby 2.1, default: 4096
.Pp
.It Ev RUBY_GC_HEAP_GROWTH_FACTOR
Increase allocation rate of heap slots by this factor.
Introduced in Ruby 2.1, default: 1.8, minimum: 1.0 (no growth)
.Pp
.It Ev RUBY_GC_HEAP_GROWTH_MAX_SLOTS
Allocation rate is limited to this number of slots,
preventing excessive allocation due to RUBY_GC_HEAP_GROWTH_FACTOR.
Introduced in Ruby 2.1, default: 0 (no limit)
.Pp
.It Ev RUBY_GC_HEAP_OLDOBJECT_LIMIT_FACTOR
Perform a full GC when the number of old objects is more than R * N,
where R is this factor and N is the number of old objects after the
last full GC.
Introduced in Ruby 2.1.1, default: 2.0
.Pp
.It Ev RUBY_GC_MALLOC_LIMIT
The initial limit of young generation allocation from the malloc-family.
GC will start when this limit is reached.
Default: 16MB
.Pp
.It Ev RUBY_GC_MALLOC_LIMIT_MAX
The maximum limit of young generation allocation from malloc before GC starts.
Prevents excessive malloc growth due to RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR.
Introduced in Ruby 2.1, default: 32MB.
.Pp
.It Ev RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR
Increases the limit of young generation malloc calls, reducing
GC frequency but increasing malloc growth until RUBY_GC_MALLOC_LIMIT_MAX
is reached.
Introduced in Ruby 2.1, default: 1.4, minimum: 1.0 (no growth)
.Pp
.It Ev RUBY_GC_OLDMALLOC_LIMIT
The initial limit of old generation allocation from malloc,
a full GC will start when this limit is reached.
Introduced in Ruby 2.1, default: 16MB
.Pp
.It Ev RUBY_GC_OLDMALLOC_LIMIT_MAX
The maximum limit of old generation allocation from malloc before a
full GC starts.
Prevents excessive malloc growth due to RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR.
Introduced in Ruby 2.1, default: 128MB
.Pp
.It Ev RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR
Increases the limit of old generation malloc allocation, reducing full
GC frequency but increasing malloc growth until RUBY_GC_OLDMALLOC_LIMIT_MAX
is reached.
Introduced in Ruby 2.1, default: 1.2, minimum: 1.0 (no growth)
.Pp
.El
.Sh STACK SIZE ENVIRONMENT
Stack size environment variables are implementation-dependent and
subject to change with different versions of Ruby. The VM stack is used
for pure-Ruby code and managed by the virtual machine. Machine stack is
used by the operating system and its usage is dependent on C extensions
as well as C compiler options. Using lower values for these may allow
applications to keep more Fibers or Threads running; but increases the
chance of SystemStackError exceptions and segmentation faults (SIGSEGV).
These environment variables are available since Ruby 2.0.0.
All values are specified in bytes.
.Pp
.Bl -hang -compact -width "RUBY_THREAD_MACHINE_STACK_SIZE"
.It Ev RUBY_THREAD_VM_STACK_SIZE
VM stack size used at thread creation.
default: 131072 (32-bit CPU) or 262144 (64-bit)
.Pp
.It Ev RUBY_THREAD_MACHINE_STACK_SIZE
Machine stack size used at thread creation.
default: 524288 or 1048575
.Pp
.It Ev RUBY_FIBER_VM_STACK_SIZE
VM stack size used at fiber creation.
default: 65536 or 131072
.Pp
.It Ev RUBY_FIBER_MACHINE_STACK_SIZE
Machine stack size used at fiber creation.
default: 262144 or 524288

.TH "BUNDLE\-PLATFORM" "1" "December 2021" "" ""
.
.SH "NAME"
\fBbundle\-platform\fR \- Displays platform compatibility information
.
.SH "SYNOPSIS"
\fBbundle platform\fR [\-\-ruby]
.
.SH "DESCRIPTION"
\fBplatform\fR will display information from your Gemfile, Gemfile\.lock, and Ruby VM about your platform\.
.
.P
For instance, using this Gemfile(5):
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
ruby "1\.9\.3"
gem "rack"
.
.fi
.
.IP "" 0
.
.P
If you run \fBbundle platform\fR on Ruby 1\.9\.3, it will display the following output:
.
.IP "" 4
.
.nf
Your platform is: x86_64\-linux
Your app has gems that work on these platforms:
* ruby
Your Gemfile specifies a Ruby version requirement:
* ruby 1\.9\.3
Your current platform satisfies the Ruby version requirement\.
.
.fi
.
.IP "" 0
.
.P
\fBplatform\fR will list all the platforms in your \fBGemfile\.lock\fR as well as the \fBruby\fR directive if applicable from your Gemfile(5)\. It will also let you know if the \fBruby\fR directive requirement has been met\. If \fBruby\fR directive doesn\'t match the running Ruby VM, it will tell you what part does not\.

.SH "NAME"
\fBbundle\-config\fR \- Set bundler configuration options
.
.SH "SYNOPSIS"
\fBbundle config\fR [list|get|set|unset] [\fIname\fR [\fIvalue\fR]]
.
.SH "DESCRIPTION"
This command allows you to interact with Bundler\'s configuration system\.
.
.P
Bundler loads configuration settings in this order:
.
.IP "1." 4
Local config (\fB<project_root>/\.bundle/config\fR or \fB$BUNDLE_APP_CONFIG/config\fR)
.
.IP "2." 4
Environmental variables (\fBENV\fR)
.
.IP "3." 4
Global config (\fB~/\.bundle/config\fR)
.
.IP "4." 4
Bundler default config
.
.IP "" 0
.
.P
Executing \fBbundle config list\fR with will print a list of all bundler configuration for the current bundle, and where that configuration was set\.
.
.P
Executing \fBbundle config get <name>\fR will print the value of that configuration setting, and where it was set\.
.
.P
Executing \fBbundle config set <name> <value>\fR will set that configuration to the value specified for all bundles executed as the current user\. The configuration will be stored in \fB~/\.bundle/config\fR\. If \fIname\fR already is set, \fIname\fR will be overridden and user will be warned\.
.
.P
Executing \fBbundle config set \-\-global <name> <value>\fR works the same as above\.
.
.P
Executing \fBbundle config set \-\-local <name> <value>\fR will set that configuration in the directory for the local application\. The configuration will be stored in \fB<project_root>/\.bundle/config\fR\. If \fBBUNDLE_APP_CONFIG\fR is set, the configuration will be stored in \fB$BUNDLE_APP_CONFIG/config\fR\.
.
.P
Executing \fBbundle config unset <name>\fR will delete the configuration in both local and global sources\.
.
.P
Executing \fBbundle config unset \-\-global <name>\fR will delete the configuration only from the user configuration\.
.
.P
Executing \fBbundle config unset \-\-local <name> <value>\fR will delete the configuration only from the local application\.
.
.P
Executing bundle with the \fBBUNDLE_IGNORE_CONFIG\fR environment variable set will cause it to ignore all configuration\.
.
.SH "REMEMBERING OPTIONS"
Flags passed to \fBbundle install\fR or the Bundler runtime, such as \fB\-\-path foo\fR or \fB\-\-without production\fR, are remembered between commands and saved to your local application\'s configuration (normally, \fB\./\.bundle/config\fR)\.
.
.P
However, this will be changed in bundler 3, so it\'s better not to rely on this behavior\. If these options must be remembered, it\'s better to set them using \fBbundle config\fR (e\.g\., \fBbundle config set \-\-local path foo\fR)\.
.
.P
The options that can be configured are:
.
.TP
\fBbin\fR
Creates a directory (defaults to \fB~/bin\fR) and place any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\.
.
.TP
\fBdeployment\fR
In deployment mode, Bundler will \'roll\-out\' the bundle for \fBproduction\fR use\. Please check carefully if you want to have this option enabled in \fBdevelopment\fR or \fBtest\fR environments\.
.
.TP
\fBpath\fR
The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\.
.
.TP
\fBwithout\fR
A space\-separated list of groups referencing gems to skip during installation\.
.
.TP
\fBwith\fR
A space\-separated list of groups referencing gems to include during installation\.
.
.SH "BUILD OPTIONS"
You can use \fBbundle config\fR to give Bundler the flags to pass to the gem installer every time bundler tries to install a particular gem\.
.
.P
A very common example, the \fBmysql\fR gem, requires Snow Leopard users to pass configuration flags to \fBgem install\fR to specify where to find the \fBmysql_config\fR executable\.
.
.IP "" 4
.
.nf
gem install mysql \-\- \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config
.
.fi
.
.IP "" 0
.
.P
Since the specific location of that executable can change from machine to machine, you can specify these flags on a per\-machine basis\.
.
.IP "" 4
.
.nf
bundle config set \-\-global build\.mysql \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config
.
.fi
.
.IP "" 0
.
.P
After running this command, every time bundler needs to install the \fBmysql\fR gem, it will pass along the flags you specified\.
.
.SH "CONFIGURATION KEYS"
Configuration keys in bundler have two forms: the canonical form and the environment variable form\.
.
.P
For instance, passing the \fB\-\-without\fR flag to bundle install(1) \fIbundle\-install\.1\.html\fR prevents Bundler from installing certain groups specified in the Gemfile(5)\. Bundler persists this value in \fBapp/\.bundle/config\fR so that calls to \fBBundler\.setup\fR do not try to find gems from the \fBGemfile\fR that you didn\'t install\. Additionally, subsequent calls to bundle install(1) \fIbundle\-install\.1\.html\fR remember this setting and skip those groups\.
.
.P
The canonical form of this configuration is \fB"without"\fR\. To convert the canonical form to the environment variable form, capitalize it, and prepend \fBBUNDLE_\fR\. The environment variable form of \fB"without"\fR is \fBBUNDLE_WITHOUT\fR\.
.
.P
Any periods in the configuration keys must be replaced with two underscores when setting it via environment variables\. The configuration key \fBlocal\.rack\fR becomes the environment variable \fBBUNDLE_LOCAL__RACK\fR\.
.
.SH "LIST OF AVAILABLE KEYS"
The following is a list of all configuration keys and their purpose\. You can learn more about their operation in bundle install(1) \fIbundle\-install\.1\.html\fR\.

.
.P
In general, you should set these settings per\-application by using the applicable flag to the bundle install(1) \fIbundle\-install\.1\.html\fR or bundle package(1) \fIbundle\-package\.1\.html\fR command\.
.
.P
You can set them globally either via environment variables or \fBbundle config\fR, whichever is preferable for your setup\. If you use both, environment variables will take preference over global settings\.
.
.SH "LOCAL GIT REPOS"
Bundler also allows you to work against a git repository locally instead of using the remote version\. This can be achieved by setting up a local override:
.
.IP "" 4
.
.nf
bundle config set \-\-local local\.GEM_NAME /path/to/local/git/repository
.
.fi
.
.IP "" 0
.
.P
For example, in order to use a local Rack repository, a developer could call:
.
.IP "" 4
.
.nf
bundle config set \-\-local local\.rack ~/Work/git/rack
.
.fi
.
.IP "" 0
.
.P
Now instead of checking out the remote git repository, the local override will be used\. Similar to a path source, every time the local git repository change, changes will be automatically picked up by Bundler\. This means a commit in the local git repo will update the revision in the \fBGemfile\.lock\fR to the local git repo revision\. This requires the same attention as git submodules\. Before pushing to the remote, you need to ensure the local override was pushed, otherwise you may point to a commit that only exists in your local machine\. You\'ll also need to CGI escape your usernames and passwords as well\.
.
.P
Bundler does many checks to ensure a developer won\'t work with invalid references\. Particularly, we force a developer to specify a branch in the \fBGemfile\fR in order to use this feature\. If the branch specified in the \fBGemfile\fR and the current branch in the local git repository do not match, Bundler will abort\. This ensures that a developer is always working against the correct branches, and prevents accidental locking to a different branch\.
.
.P
Finally, Bundler also ensures that the current revision in the \fBGemfile\.lock\fR exists in the local git repository\. By doing this, Bundler forces you to fetch the latest changes in the remotes\.
.
.SH "MIRRORS OF GEM SOURCES"
Bundler supports overriding gem sources with mirrors\. This allows you to configure rubygems\.org as the gem source in your Gemfile while still using your mirror to fetch gems\.
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.SOURCE_URL MIRROR_URL
.
.fi
.
.IP "" 0
.
.P
For example, to use a mirror of rubygems\.org hosted at rubygems\-mirror\.org:
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.http://rubygems\.org http://rubygems\-mirror\.org
.
.fi
.
.IP "" 0
.
.P
Each mirror also provides a fallback timeout setting\. If the mirror does not respond within the fallback timeout, Bundler will try to use the original server instead of the mirror\.
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.SOURCE_URL\.fallback_timeout TIMEOUT
.
.fi
.
.IP "" 0
.
.P
For example, to fall back to rubygems\.org after 3 seconds:
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.https://rubygems\.org\.fallback_timeout 3
.
.fi
.
.IP "" 0
.
.P
The default fallback timeout is 0\.1 seconds, but the setting can currently only accept whole seconds (for example, 1, 15, or 30)\.
.
.SH "CREDENTIALS FOR GEM SOURCES"
Bundler allows you to configure credentials for any gem source, which allows you to avoid putting secrets into your Gemfile\.
.
.IP "" 4
.
.nf
bundle config set \-\-global SOURCE_HOSTNAME USERNAME:PASSWORD
.
.fi
.
.IP "" 0
.
.P
For example, to save the credentials of user \fBclaudette\fR for the gem source at \fBgems\.longerous\.com\fR, you would run:
.
.IP "" 4
.
.nf
bundle config set \-\-global gems\.longerous\.com claudette:s00pers3krit
.
.fi
.
.IP "" 0
.
.P
Or you can set the credentials as an environment variable like this:
.
.IP "" 4
.
.nf
export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit"
.
.fi
.
.IP "" 0
.
.P
For gems with a git source with HTTP(S) URL you can specify credentials like so:
.
.IP "" 4
.
.nf
bundle config set \-\-global https://github\.com/rubygems/rubygems\.git username:password
.
.fi
.
.IP "" 0
.
.P
Or you can set the credentials as an environment variable like so:
.
.IP "" 4
.
.nf
export BUNDLE_GITHUB__COM=username:password
.
.fi
.
.IP "" 0
.
.P
This is especially useful for private repositories on hosts such as Github, where you can use personal OAuth tokens:
.
.IP "" 4
.
.nf
export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x\-oauth\-basic
.
.fi
.
.IP "" 0
.
.P
Note that any configured credentials will be redacted by informative commands such as \fBbundle config list\fR or \fBbundle config get\fR, unless you use the \fB\-\-parseable\fR flag\. This is to avoid unintentionally leaking credentials when copy\-pasting bundler output\.
.
.P
Also note that to guarantee a sane mapping between valid environment variable names and valid host names, bundler makes the following transformations:
.
.IP "\(bu" 4
Any \fB\-\fR characters in a host name are mapped to a triple dash (\fB___\fR) in the corresponding environment variable\.
.
.IP "\(bu" 4
Any \fB\.\fR characters in a host name are mapped to a double dash (\fB__\fR) in the corresponding environment variable\.
.
.IP "" 0
.
.P
This means that if you have a gem server named \fBmy\.gem\-host\.com\fR, you\'ll need to use the \fBBUNDLE_MY__GEM___HOST__COM\fR variable to configure credentials for it through ENV\.
.
.SH "CONFIGURE BUNDLER DIRECTORIES"
Bundler\'s home, config, cache and plugin directories are able to be configured through environment variables\. The default location for Bundler\'s home directory is \fB~/\.bundle\fR, which all directories inherit from by default\. The following outlines the available environment variables and their default values
.
.IP "" 4

.nf
BUNDLE_USER_HOME : $HOME/\.bundle

.
.SH "DESCRIPTION"
Outdated lists the names and versions of gems that have a newer version available in the given source\. Calling outdated with [GEM [GEM]] will only check for newer versions of the given gems\. Prerelease gems are ignored by default\. If your gems are up to date, Bundler will exit with a status of 0\. Otherwise, it will exit 1\.
.

See bundle update(1) \fIbundle\-update\.1\.html\fR for details\.
.
.P
One difference between the patch level options in \fBbundle update\fR and here is the \fB\-\-strict\fR option\. \fB\-\-strict\fR was already an option on outdated before the patch level options were added\. \fB\-\-strict\fR wasn\'t altered, and the \fB\-\-update\-strict\fR option on \fBoutdated\fR reflects what \fB\-\-strict\fR does on \fBbundle update\fR\.

.
.SH "SYNOPSIS"
\fBbundle pristine\fR
.
.SH "DESCRIPTION"
\fBpristine\fR restores the installed gems in the bundle to their pristine condition using the local gem cache from RubyGems\. For git gems, a forced checkout will be performed\.
.
.P
For further explanation, \fBbundle pristine\fR ignores unpacked files on disk\. In other words, this command utilizes the local \fB\.gem\fR cache or the gem\'s git repository as if one were installing from scratch\.
.
.P
Note: the Bundler gem cannot be restored to its original state with \fBpristine\fR\. One also cannot use \fBbundle pristine\fR on gems with a \'path\' option in the Gemfile, because bundler has no original copy it can restore from\.
.
.P
When is it practical to use \fBbundle pristine\fR?
.
.P
It comes in handy when a developer is debugging a gem\. \fBbundle pristine\fR is a great way to get rid of experimental changes to a gem that one may not want\.
.
.P
Why use \fBbundle pristine\fR over \fBgem pristine \-\-all\fR?
.
.P
Both commands are very similar\. For context: \fBbundle pristine\fR, without arguments, cleans all gems from the lockfile\. Meanwhile, \fBgem pristine \-\-all\fR cleans all installed gems for that Ruby version\.
.
.P
If a developer forgets which gems in their project they might have been debugging, the Rubygems \fBgem pristine [GEMNAME]\fR command may be inconvenient\. One can avoid waiting for \fBgem pristine \-\-all\fR, and instead run \fBbundle pristine\fR\.

.
.SH "DESCRIPTION"
Install the gems specified in your Gemfile(5)\. If this is the first time you run bundle install (and a \fBGemfile\.lock\fR does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems\.
.
.P
If a \fBGemfile\.lock\fR does exist, and you have not updated your Gemfile(5), Bundler will fetch all remote sources, but use the dependencies specified in the \fBGemfile\.lock\fR instead of resolving dependencies\.
.
.P
If a \fBGemfile\.lock\fR does exist, and you have updated your Gemfile(5), Bundler will use the dependencies in the \fBGemfile\.lock\fR for all gems that you did not update, but will re\-resolve the dependencies of gems that you did update\. You can find more information about this update process below under \fICONSERVATIVE UPDATING\fR\.
.
.SH "OPTIONS"
The \fB\-\-clean\fR, \fB\-\-deployment\fR, \fB\-\-frozen\fR, \fB\-\-no\-prune\fR, \fB\-\-path\fR, \fB\-\-shebang\fR, \fB\-\-system\fR, \fB\-\-without\fR and \fB\-\-with\fR options are deprecated because they only make sense if they are applied to every subsequent \fBbundle install\fR run automatically and that requires \fBbundler\fR to silently remember them\. Since \fBbundler\fR will no longer remember CLI flags in future versions, \fBbundle config\fR (see bundle\-config(1)) should be used to apply them permanently\.
.
.TP
\fB\-\-binstubs[=<directory>]\fR
Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it in \fBbin/\fR\. This lets you link the binstub inside of an application to the exact gem version the application needs\.
.
.IP
Creates a directory (defaults to \fB~/bin\fR) and places any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\.
.
.TP
\fB\-\-clean\fR
On finishing the installation Bundler is going to remove any gems not present in the current Gemfile(5)\. Don\'t worry, gems currently in use will not be removed\.
.
.IP
This option is deprecated in favor of the \fBclean\fR setting\.
.
.TP
\fB\-\-deployment\fR
In \fIdeployment mode\fR, Bundler will \'roll\-out\' the bundle for production or CI use\. Please check carefully if you want to have this option enabled in your development environment\.

.TP
\fB\-\-redownload\fR
Force download every gem, even if the required versions are already available locally\.
.

\fB\-\-frozen\fR
Do not allow the Gemfile\.lock to be updated after this install\. Exits non\-zero if there are going to be changes to the Gemfile\.lock\.
.
.IP
This option is deprecated in favor of the \fBfrozen\fR setting\.
.
.TP
\fB\-\-full\-index\fR
Bundler will not call Rubygems\' API endpoint (default) but download and cache a (currently big) index file of all gems\. Performance can be improved for large bundles that seldom change by enabling this option\.
.
.TP
\fB\-\-gemfile=<gemfile>\fR
The location of the Gemfile(5) which Bundler should use\. This defaults to a Gemfile(5) in the current working directory\. In general, Bundler will assume that the location of the Gemfile(5) is also the project\'s root and will try to find \fBGemfile\.lock\fR and \fBvendor/cache\fR relative to this location\.
.
.TP
\fB\-\-jobs=[<number>]\fR, \fB\-j[<number>]\fR
The maximum number of parallel download and install jobs\. The default is \fB1\fR\.
.
.TP
\fB\-\-local\fR
Do not attempt to connect to \fBrubygems\.org\fR\. Instead, Bundler will use the gems already present in Rubygems\' cache or in \fBvendor/cache\fR\. Note that if an appropriate platform\-specific gem exists on \fBrubygems\.org\fR it will not be found\.
.
.TP
\fB\-\-no\-cache\fR
Do not update the cache in \fBvendor/cache\fR with the newly bundled gems\. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install\.
.

\fB\-\-no\-prune\fR
Don\'t remove stale gems from the cache when the installation finishes\.
.
.IP
This option is deprecated in favor of the \fBno_prune\fR setting\.

.TP
\fB\-\-path=<path>\fR
The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\.

\fB\-\-shebang=<ruby\-executable>\fR
Uses the specified ruby executable (usually \fBruby\fR) to execute the scripts created with \fB\-\-binstubs\fR\. In addition, if you use \fB\-\-binstubs\fR together with \fB\-\-shebang jruby\fR these executables will be changed to execute \fBjruby\fR instead\.

\fB\-\-standalone[=<list>]\fR
Makes a bundle that can work without depending on Rubygems or Bundler at runtime\. A space separated list of groups to install has to be specified\. Bundler creates a directory named \fBbundle\fR and installs the bundle there\. It also generates a \fBbundle/bundler/setup\.rb\fR file to replace Bundler\'s own setup in the manner required\. Using this option implicitly sets \fBpath\fR, which is a [remembered option][REMEMBERED OPTIONS]\.

This option is deprecated in favor of the \fBwithout\fR setting\.
.
.SH "DEPLOYMENT MODE"
Bundler\'s defaults are optimized for development\. To switch to defaults optimized for deployment and for CI, use the \fB\-\-deployment\fR flag\. Do not activate deployment mode on development machines, as it will cause an error when the Gemfile(5) is modified\.
.
.IP "1." 4
A \fBGemfile\.lock\fR is required\.
.
.IP
To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a \fBGemfile\.lock\fR is required\.
.
.IP
This is mainly to ensure that you remember to check your \fBGemfile\.lock\fR into version control\.
.
.IP "2." 4
The \fBGemfile\.lock\fR must be up to date
.
.IP
In development, you can modify your Gemfile(5) and re\-run \fBbundle install\fR to \fIconservatively update\fR your \fBGemfile\.lock\fR snapshot\.
.
.IP
In deployment, your \fBGemfile\.lock\fR should be up\-to\-date with changes made in your Gemfile(5)\.
.
.IP "3." 4
Gems are installed to \fBvendor/bundle\fR not your default system location
.
.IP
In development, it\'s convenient to share the gems used in your application with other applications and other scripts that run on the system\.
.
.IP
In deployment, isolation is a more important default\. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them\.
.
.IP
As a result, \fBbundle install \-\-deployment\fR installs gems to the \fBvendor/bundle\fR directory in the application\. This may be overridden using the \fB\-\-path\fR option\.
.
.IP "" 0
.
.SH "SUDO USAGE"
By default, Bundler installs gems to the same location as \fBgem install\fR\.
.
.P
In some cases, that location may not be writable by your Unix user\. In that case, Bundler will stage everything in a temporary directory, then ask you for your \fBsudo\fR password in order to copy the gems into their system location\.
.
.P
From your perspective, this is identical to installing the gems directly into the system\.
.
.P
You should never use \fBsudo bundle install\fR\. This is because several other steps in \fBbundle install\fR must be performed as the current user:
.
.IP "\(bu" 4
Updating your \fBGemfile\.lock\fR
.
.IP "\(bu" 4
Updating your \fBvendor/cache\fR, if necessary
.
.IP "\(bu" 4
Checking out private git repositories using your user\'s SSH keys
.
.IP "" 0
.
.P
Of these three, the first two could theoretically be performed by \fBchown\fRing the resulting files to \fB$SUDO_USER\fR\. The third, however, can only be performed by invoking the \fBgit\fR command as the current user\. Therefore, git gems are downloaded and installed into \fB~/\.bundle\fR rather than $GEM_HOME or $BUNDLE_PATH\.
.
.P
As a result, you should run \fBbundle install\fR as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location\.
.
.SH "INSTALLING GROUPS"
By default, \fBbundle install\fR will install all gems in all groups in your Gemfile(5), except those declared for a different platform\.
.
.P
However, you can explicitly tell Bundler to skip installing certain groups with the \fB\-\-without\fR option\. This option takes a space\-separated list of groups\.
.
.P
While the \fB\-\-without\fR option will skip \fIinstalling\fR the gems in the specified groups, it will still \fIdownload\fR those gems and use them to resolve the dependencies of every gem in your Gemfile(5)\.
.
.P
This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against\.
.
.P
\fBBundler offers a rock\-solid guarantee that the third\-party code you are running in development and testing is also the third\-party code you are running in production\. You can choose to exclude some of that code in different environments, but you will never be caught flat\-footed by different versions of third\-party code being used in different environments\.\fR
.
.P
For a simple illustration, consider the following Gemfile(5):
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'sinatra\'
group :production do
gem \'rack\-perftools\-profiler\'
end
.
.fi
.
.IP "" 0
.
.P
In this case, \fBsinatra\fR depends on any version of Rack (\fB>= 1\.0\fR), while \fBrack\-perftools\-profiler\fR depends on 1\.x (\fB~> 1\.0\fR)\.
.
.P
When you run \fBbundle install \-\-without production\fR in development, we look at the dependencies of \fBrack\-perftools\-profiler\fR as well\. That way, you do not spend all your time developing against Rack 2\.0, using new APIs unavailable in Rack 1\.x, only to have Bundler switch to Rack 1\.2 when the \fBproduction\fR group \fIis\fR used\.
.
.P
This should not cause any problems in practice, because we do not attempt to \fBinstall\fR the gems in the excluded groups, and only evaluate as part of the dependency resolution process\.
.
.P
This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production\. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using\.
.
.SH "THE GEMFILE\.LOCK"
When you run \fBbundle install\fR, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called \fBGemfile\.lock\fR\.
.
.P
Bundler uses this file in all subsequent calls to \fBbundle install\fR, which guarantees that you always use the same exact code, even as your application moves across machines\.
.
.P
Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point\-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies\.
.
.P
As a result, you \fBSHOULD\fR check your \fBGemfile\.lock\fR into version control, in both applications and gems\. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third\-party code being used if \fBany\fR of the gems in the Gemfile(5) or any of their dependencies have been updated\.
.
.P
When Bundler first shipped, the \fBGemfile\.lock\fR was included in the \fB\.gitignore\fR file included with generated gems\. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem\. Since \fBbundle install\fR is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing\. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems\.
.
.SH "CONSERVATIVE UPDATING"
When you make a change to the Gemfile(5) and then run \fBbundle install\fR, Bundler will update only the gems that you modified\.
.
.P
In other words, if a gem that you \fBdid not modify\fR worked before you called \fBbundle install\fR, it will continue to use the exact same versions of all dependencies as it used before the update\.
.
.P
Let\'s take a look at an example\. Here\'s your original Gemfile(5):
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'actionpack\', \'2\.3\.8\'
gem \'activemerchant\'
.
.fi
.
.IP "" 0
.
.P
In this case, both \fBactionpack\fR and \fBactivemerchant\fR depend on \fBactivesupport\fR\. The \fBactionpack\fR gem depends on \fBactivesupport 2\.3\.8\fR and \fBrack ~> 1\.1\.0\fR, while the \fBactivemerchant\fR gem depends on \fBactivesupport >= 2\.3\.2\fR, \fBbraintree >= 2\.0\.0\fR, and \fBbuilder >= 2\.0\.0\fR\.
.
.P
When the dependencies are first resolved, Bundler will select \fBactivesupport 2\.3\.8\fR, which satisfies the requirements of both gems in your Gemfile(5)\.
.
.P
Next, you modify your Gemfile(5) to:
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'actionpack\', \'3\.0\.0\.rc\'
gem \'activemerchant\'
.
.fi
.
.IP "" 0
.
.P
The \fBactionpack 3\.0\.0\.rc\fR gem has a number of new dependencies, and updates the \fBactivesupport\fR dependency to \fB= 3\.0\.0\.rc\fR and the \fBrack\fR dependency to \fB~> 1\.2\.1\fR\.
.
.P
When you run \fBbundle install\fR, Bundler notices that you changed the \fBactionpack\fR gem, but not the \fBactivemerchant\fR gem\. It evaluates the gems currently being used to satisfy its requirements:
.
.TP
\fBactivesupport 2\.3\.8\fR
also used to satisfy a dependency in \fBactivemerchant\fR, which is not being updated
.
.TP
\fBrack ~> 1\.1\.0\fR
not currently being used to satisfy another dependency
.
.P
Because you did not explicitly ask to update \fBactivemerchant\fR, you would not expect it to suddenly stop working after updating \fBactionpack\fR\. However, satisfying the new \fBactivesupport 3\.0\.0\.rc\fR dependency of actionpack requires updating one of its dependencies\.
.
.P
Even though \fBactivemerchant\fR declares a very loose dependency that theoretically matches \fBactivesupport 3\.0\.0\.rc\fR, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies\. In this case, the \fBactivemerchant\fR dependency is treated as \fBactivemerchant 1\.7\.1 + activesupport 2\.3\.8\fR, so \fBbundle install\fR will report that it cannot update \fBactionpack\fR\.
.
.P
To explicitly update \fBactionpack\fR, including its dependencies which other gems in the Gemfile(5) still depend on, run \fBbundle update actionpack\fR (see \fBbundle update(1)\fR)\.
.
.P
\fBSummary\fR: In general, after making a change to the Gemfile(5) , you should first try to run \fBbundle install\fR, which will guarantee that no other gem in the Gemfile(5) is impacted by the change\. If that does not work, run bundle update(1) \fIbundle\-update\.1\.html\fR\.

\fBbundle cache\fR
.

Copy all of the \fB\.gem\fR files needed to run the application into the \fBvendor/cache\fR directory\. In the future, when running [bundle install(1)][bundle\-install], use the gems in the cache in preference to the ones on \fBrubygems\.org\fR\.

The \fBbundle cache\fR command can also package \fB:git\fR and \fB:path\fR dependencies besides \.gem files\. This needs to be explicitly enabled via the \fB\-\-all\fR option\. Once used, the \fB\-\-all\fR option will be remembered\.
.
.SH "SUPPORT FOR MULTIPLE PLATFORMS"
When using gems that have different packages for different platforms, Bundler supports caching of gems for other platforms where the Gemfile has been resolved (i\.e\. present in the lockfile) in \fBvendor/cache\fR\. This needs to be enabled via the \fB\-\-all\-platforms\fR option\. This setting will be remembered in your local bundler configuration\.
.
.SH "REMOTE FETCHING"
By default, if you run \fBbundle install(1)\fR](bundle\-install\.1\.html) after running bundle cache(1) \fIbundle\-cache\.1\.html\fR, bundler will still connect to \fBrubygems\.org\fR to check whether a platform\-specific gem exists for any of the gems in \fBvendor/cache\fR\.
.
.P
For instance, consider this Gemfile(5):
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
gem "nokogiri"
.
.fi
.
.IP "" 0
.
.P
If you run \fBbundle cache\fR under C Ruby, bundler will retrieve the version of \fBnokogiri\fR for the \fB"ruby"\fR platform\. If you deploy to JRuby and run \fBbundle install\fR, bundler is forced to check to see whether a \fB"java"\fR platformed \fBnokogiri\fR exists\.
.
.P
Even though the \fBnokogiri\fR gem for the Ruby platform is \fItechnically\fR acceptable on JRuby, it has a C extension that does not run on JRuby\. As a result, bundler will, by default, still connect to \fBrubygems\.org\fR to check whether it has a version of one of your gems more specific to your platform\.
.
.P
This problem is also not limited to the \fB"java"\fR platform\. A similar (common) problem can happen when developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux\.
.
.P
If you know for sure that the gems packaged in \fBvendor/cache\fR are appropriate for the platform you are on, you can run \fBbundle install \-\-local\fR to skip checking for more appropriate gems, and use the ones in \fBvendor/cache\fR\.
.
.P
One way to be sure that you have the right platformed versions of all your gems is to run \fBbundle cache\fR on an identical machine and check in the gems\. For instance, you can run \fBbundle cache\fR on an identical staging box during your staging process, and check in the \fBvendor/cache\fR before deploying to production\.
.
.P
By default, bundle cache(1) \fIbundle\-cache\.1\.html\fR fetches and also installs the gems to the default location\. To package the dependencies to \fBvendor/cache\fR without installing them to the local install location, you can run \fBbundle cache \-\-no\-install\fR\.

\fBbundle binstubs\fR \fIGEM_NAME\fR [\-\-force] [\-\-path PATH] [\-\-standalone]
.
.SH "DESCRIPTION"
Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it into \fBbin/\fR\. Binstubs are a shortcut\-or alternative\- to always using \fBbundle exec\fR\. This gives you a file that can be run directly, and one that will always run the correct gem version used by the application\.
.

For example, if you run \fBbundle binstubs rspec\-core\fR, Bundler will create the file \fBbin/rspec\fR\. That file will contain enough code to load Bundler, tell it to load the bundled gems, and then run rspec\.

.P
This command generates binstubs for executables in \fBGEM_NAME\fR\. Binstubs are put into \fBbin\fR, or the \fB\-\-path\fR directory if one has been set\. Calling binstubs with [GEM [GEM]] will create binstubs for all given gems\.

This command executes the command, making all gems specified in the [\fBGemfile(5)\fR][Gemfile(5)] available to \fBrequire\fR in Ruby programs\.

Essentially, if you would normally have run something like \fBrspec spec/my_spec\.rb\fR, and you want to use the gems specified in the [\fBGemfile(5)\fR][Gemfile(5)] and installed via bundle install(1) \fIbundle\-install\.1\.html\fR, you should run \fBbundle exec rspec spec/my_spec\.rb\fR\.

Note that \fBbundle exec\fR does not require that an executable is available on your shell\'s \fB$PATH\fR\.
.
.SH "OPTIONS"

Exec in Ruby 2\.0 began discarding non\-standard file descriptors\. When this flag is passed, exec will revert to the 1\.9 behaviour of passing all file descriptors to the new process\.

.
.IP "\(bu" 4

.
.IP "" 0
.
.P
Finally, \fBbundle exec\fR also implicitly modifies \fBGemfile\.lock\fR if the lockfile and the Gemfile do not match\. Bundler needs the Gemfile to determine things such as a gem\'s groups, \fBautorequire\fR, and platforms, etc\., and that information isn\'t stored in the lockfile\. The Gemfile and lockfile must be synced in order to \fBbundle exec\fR successfully, so \fBbundle exec\fR updates the lockfile beforehand\.
.
.SS "Loading"
By default, when attempting to \fBbundle exec\fR to a file with a ruby shebang, Bundler will \fBKernel\.load\fR that file instead of using \fBKernel\.exec\fR\. For the vast majority of cases, this is a performance improvement\. In a rare few cases, this could cause some subtle side\-effects (such as dependence on the exact contents of \fB$0\fR or \fB__FILE__\fR) and the optimization can be disabled by enabling the \fBdisable_exec_load\fR setting\.
.
.SS "Shelling out"
Any Ruby code that opens a subshell (like \fBsystem\fR, backticks, or \fB%x{}\fR) will automatically use the current Bundler environment\. If you need to shell out to a Ruby command that is not part of your current bundle, use the \fBwith_clean_env\fR method with a block\. Any subshells created inside the block will be given the environment present before Bundler was activated\. For example, Homebrew commands run Ruby, but don\'t work inside a bundle:
.
.IP "" 4
.
.nf
Bundler\.with_clean_env do
`brew install wget`
end
.
.fi
.
.IP "" 0
.
.P
Using \fBwith_clean_env\fR is also necessary if you are shelling out to a different bundle\. Any Bundler commands run in a subshell will inherit the current Gemfile, so commands that need to run in the context of a different bundle also need to use \fBwith_clean_env\fR\.
.

.SH "RUBYGEMS PLUGINS"
At present, the Rubygems plugin system requires all files named \fBrubygems_plugin\.rb\fR on the load path of \fIany\fR installed gem when any Ruby code requires \fBrubygems\.rb\fR\. This includes executables installed into the system, like \fBrails\fR, \fBrackup\fR, and \fBrspec\fR\.
.
.P
Since Rubygems plugins can contain arbitrary Ruby code, they commonly end up activating themselves or their dependencies\.
.
.P
For instance, the \fBgemcutter 0\.5\fR gem depended on \fBjson_pure\fR\. If you had that version of gemcutter installed (even if you \fIalso\fR had a newer version without this problem), Rubygems would activate \fBgemcutter 0\.5\fR and \fBjson_pure <latest>\fR\.
.
.P
If your Gemfile(5) also contained \fBjson_pure\fR (or a gem with a dependency on \fBjson_pure\fR), the latest version on your system might conflict with the version in your Gemfile(5), or the snapshot version in your \fBGemfile\.lock\fR\.
.
.P
If this happens, bundler will say:
.

You have already activated json_pure 1\.4\.6 but your Gemfile
requires json_pure 1\.4\.3\. Consider using bundle exec\.

# (time-of-check-to-time-of-use) local security vulnerability of rm_r.
# #rm_r causes security hole when:
#
# * Parent directory is world writable (including /tmp).
# * Removing directory tree includes world writable directory.
# * The system has symbolic link.
#
# To avoid this security hole, this method applies special preprocess.
# If +path+ is a directory, this method chown(2) and chmod(2) all
# removing directories. This requires the current process is the
# owner of the removing whole directory tree, or is the super user (root).
#
# WARNING: You must ensure that *ALL* parent directories cannot be
# moved by other untrusted users. For example, parent directories
# should not be owned by untrusted users, and should not be world
# writable except when the sticky bit set.
#
# WARNING: Only the owner of the removing directory tree, or Unix super
# user (root) should invoke this method. Otherwise this method does not
# work.
#
# For details of this security vulnerability, see Perl's case:
#
# * https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0448
# * https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0452

#
# == Overview
#
# The Benchmark module provides methods for benchmarking Ruby code, giving
# detailed reports on the time taken for each task.
#
# The Benchmark module provides methods to measure and report the time
# used to execute Ruby code.
#
# * Measure the time to construct the string given by the expression
# <code>"a"*1_000_000_000</code>:
#
# require 'benchmark'
#
# puts Benchmark.measure { "a"*1_000_000_000 }
#
# On my machine (OSX 10.8.3 on i5 1.7 GHz) this generates:
#
# 0.350000 0.400000 0.750000 ( 0.835234)
#
# This report shows the user CPU time, system CPU time, the sum of
# the user and system CPU times, and the elapsed real time. The unit
# of time is seconds.
#
# * Do some experiments sequentially using the #bm method:
#
# require 'benchmark'
#
# n = 5000000
# Benchmark.bm do |x|
# x.report { for i in 1..n; a = "1"; end }
# x.report { n.times do ; a = "1"; end }
# x.report { 1.upto(n) do ; a = "1"; end }
# end
#
# The result:
#
# user system total real
# 1.010000 0.000000 1.010000 ( 1.014479)
# 1.000000 0.000000 1.000000 ( 0.998261)
# 0.980000 0.000000 0.980000 ( 0.981335)
#
# * Continuing the previous example, put a label in each report:
#
# require 'benchmark'
#
# n = 5000000
# Benchmark.bm(7) do |x|
# x.report("for:") { for i in 1..n; a = "1"; end }
# x.report("times:") { n.times do ; a = "1"; end }
# x.report("upto:") { 1.upto(n) do ; a = "1"; end }
# end
#
# The result:
#
# user system total real
# for: 1.010000 0.000000 1.010000 ( 1.015688)
# times: 1.000000 0.000000 1.000000 ( 1.003611)
# upto: 1.030000 0.000000 1.030000 ( 1.028098)
#
# * The times for some benchmarks depend on the order in which items
# are run. These differences are due to the cost of memory
# allocation and garbage collection. To avoid these discrepancies,
# the #bmbm method is provided. For example, to compare ways to
# sort an array of floats:
#
# require 'benchmark'
#
# array = (1..1000000).map { rand }
#
# Benchmark.bmbm do |x|
# x.report("sort!") { array.dup.sort! }
# x.report("sort") { array.dup.sort }
# end
#
# The result:
#
# Rehearsal -----------------------------------------
# sort! 1.490000 0.010000 1.500000 ( 1.490520)
# sort 1.460000 0.000000 1.460000 ( 1.463025)
# -------------------------------- total: 2.960000sec
#
# user system total real
# sort! 1.460000 0.000000 1.460000 ( 1.460465)
# sort 1.450000 0.010000 1.460000 ( 1.448327)
#
# * Report statistics of sequential experiments with unique labels,
# using the #benchmark method:
#
# require 'benchmark'
# include Benchmark # we need the CAPTION and FORMAT constants
#
# n = 5000000
# Benchmark.benchmark(CAPTION, 7, FORMAT, ">total:", ">avg:") do |x|
# tf = x.report("for:") { for i in 1..n; a = "1"; end }
# tt = x.report("times:") { n.times do ; a = "1"; end }
# tu = x.report("upto:") { 1.upto(n) do ; a = "1"; end }
# [tf+tt+tu, (tf+tt+tu)/3]
# end
#
# The result:
#
# user system total real
# for: 0.950000 0.000000 0.950000 ( 0.952039)
# times: 0.980000 0.000000 0.980000 ( 0.984938)
# upto: 0.950000 0.000000 0.950000 ( 0.946787)
# >total: 2.880000 0.000000 2.880000 ( 2.883764)

module Benchmark
BENCHMARK_VERSION = "2002-04-25" # :nodoc:
# Invokes the block with a Benchmark::Report object, which
# may be used to collect and report on the results of individual
# benchmark tests. Reserves +label_width+ leading spaces for
# labels on each line. Prints +caption+ at the top of the
# report, and uses +format+ to format each line.
# Returns an array of Benchmark::Tms objects.
#
# If the block returns an array of
# Benchmark::Tms objects, these will be used to format
# additional lines of output. If +labels+ parameter are
# given, these are used to label these extra lines.
#
# _Note_: Other methods provide a simpler interface to this one, and are
# suitable for nearly all benchmarking requirements. See the examples in
# Benchmark, and the #bm and #bmbm methods.
#
# Example:
#
# require 'benchmark'
# include Benchmark # we need the CAPTION and FORMAT constants
#
# n = 5000000
# Benchmark.benchmark(CAPTION, 7, FORMAT, ">total:", ">avg:") do |x|
# tf = x.report("for:") { for i in 1..n; a = "1"; end }
# tt = x.report("times:") { n.times do ; a = "1"; end }
# tu = x.report("upto:") { 1.upto(n) do ; a = "1"; end }

# Sometimes benchmark results are skewed because code executed
# earlier encounters different garbage collection overheads than
# that run later. #bmbm attempts to minimize this effect by running
# the tests twice, the first time as a rehearsal in order to get the
# runtime environment stable, the second time for
# real. GC.start is executed before the start of each of
# the real timings; the cost of this is not included in the
# timings. In reality, though, there's only so much that #bmbm can
# do, and the results are not guaranteed to be isolated from garbage
# collection and other effects.

# Because #bmbm takes two passes through the tests, it can
# calculate the required label width.

#
# == Features
#
# This library extends the Time class with the following conversions between
# date strings and Time objects:
#
# * date-time defined by {RFC 2822}[http://www.ietf.org/rfc/rfc2822.txt]
# * HTTP-date defined by {RFC 2616}[http://www.ietf.org/rfc/rfc2616.txt]
# * dateTime defined by XML Schema Part 2: Datatypes ({ISO
# 8601}[http://www.iso.org/iso/date_and_time_format])
# * various formats handled by Date._parse
# * custom formats handled by Date._strptime

# If a block is given, the year described in +date+ is converted
# by the block. This is specifically designed for handling two
# digit years. For example, if you wanted to treat all two digit
# years prior to 70 as the year 2000+ you could write this:
#
# require 'time'
#
# Time.parse("01-10-31") {|year| year + (year < 70 ? 2000 : 1900)}
# #=> 2001-10-31 00:00:00 -0500
# Time.parse("70-10-31") {|year| year + (year < 70 ? 2000 : 1900)}
# #=> 1970-10-31 00:00:00 -0500
#
# If the upper components of the given time are broken or missing, they are
# supplied with those of +now+. For the lower components, the minimum
# values (1 or 0) are assumed if broken or missing. For example:
#
# require 'time'
#
# # Suppose it is "Thu Nov 29 14:33:20 2001" now and
# # your time zone is EST which is GMT-5.
# now = Time.parse("Thu Nov 29 14:33:20 2001")
# Time.parse("16:30", now) #=> 2001-11-29 16:30:00 -0500
# Time.parse("7/23", now) #=> 2001-07-23 00:00:00 -0500
# Time.parse("Aug 31", now) #=> 2001-08-31 00:00:00 -0500
# Time.parse("Aug 2000", now) #=> 2000-08-01 00:00:00 -0500
#
# Since there are numerous conflicts among locally defined time zone
# abbreviations all over the world, this method is not intended to
# understand all of them. For example, the abbreviation "CST" is
# used variously as:
#
# -06:00 in America/Chicago,
# -05:00 in America/Havana,
# +08:00 in Asia/Harbin,
# +09:30 in Australia/Darwin,
# +10:30 in Australia/Adelaide,
# etc.
#
# Based on this fact, this method only understands the time zone
# abbreviations described in RFC 822 and the system time zone, in the
# order named. (i.e. a definition in RFC 822 overrides the system
# time zone definition.) The system time zone is taken from
# <tt>Time.local(year, 1, 1).zone</tt> and
# <tt>Time.local(year, 7, 1).zone</tt>.
# If the extracted time zone abbreviation does not match any of them,
# it is ignored and the given time is regarded as a local time.
#
# ArgumentError is raised if Date._parse cannot extract information from
# +date+ or if the Time class cannot represent specified date.
#
# This method can be used as a fail-safe for other parsing methods as:
#
# Time.rfc2822(date) rescue Time.parse(date)
# Time.httpdate(date) rescue Time.parse(date)
# Time.xmlschema(date) rescue Time.parse(date)
#
# A failure of Time.parse should be checked, though.
#
# You must require 'time' to use this method.

#
# Works similar to +parse+ except that instead of using a

# == Description
#
# The Logger class provides a simple but sophisticated logging utility that
# you can use to output messages.
#
# The messages have associated levels, such as +INFO+ or +ERROR+ that indicate
# their importance. You can then give the Logger a level, and only messages
# at that level or higher will be printed.
#
# The levels are:
#
# +UNKNOWN+:: An unknown message that should always be logged.
# +FATAL+:: An unhandleable error that results in a program crash.
# +ERROR+:: A handleable error condition.
# +WARN+:: A warning.
# +INFO+:: Generic (useful) information about system operation.
# +DEBUG+:: Low-level information for developers.
#
# For instance, in a production system, you may have your Logger set to
# +INFO+ or even +WARN+.
# When you are developing the system, however, you probably
# want to know about the program's internal state, and would set the Logger to
# +DEBUG+.
#
# *Note*: Logger does not escape or sanitize any messages passed to it.
# Developers should be aware of when potentially malicious data (user-input)
# is passed to Logger, and manually escape the untrusted data:
#
# logger.info("User-input: #{input.dump}")
# logger.info("User-input: %p" % input)
#
# You can use #formatter= for escaping all data.
#
# original_formatter = Logger::Formatter.new
# logger.formatter = proc { |severity, datetime, progname, msg|
# original_formatter.call(severity, datetime, progname, msg.dump)
# }
# logger.info(input)
#
# === Example
#
# This creates a Logger that outputs to the standard output stream, with a
# level of +WARN+:
#
# require 'logger'
#
# logger = Logger.new(STDOUT)
# logger.level = Logger::WARN
#
# logger.debug("Created logger")
# logger.info("Program started")
# logger.warn("Nothing to do!")
#
# path = "a_non_existent_file"
#
# begin
# File.foreach(path) do |line|
# unless line =~ /^(\w+) = (.*)$/
# logger.error("Line in wrong format: #{line.chomp}")
# end
# end
# rescue => err
# logger.fatal("Caught exception; exiting")
# logger.fatal(err)
# end
#
# Because the Logger's level is set to +WARN+, only the warning, error, and
# fatal messages are recorded. The debug and info messages are silently
# discarded.
#
# === Features
#
# There are several interesting features that Logger provides, like
# auto-rolling of log files, setting the format of log messages, and
# specifying a program name in conjunction with the message. The next section
# shows you how to achieve these things.
#
#
# == HOWTOs
#
# === How to create a logger
#
# The options below give you various choices, in more or less increasing
# complexity.
#
# 1. Create a logger which logs messages to STDERR/STDOUT.
#
# logger = Logger.new(STDERR)
# logger = Logger.new(STDOUT)
#
# 2. Create a logger for the file which has the specified name.
#
# logger = Logger.new('logfile.log')
#
# 3. Create a logger for the specified file.
#
# file = File.open('foo.log', File::WRONLY | File::APPEND)
# # To create new logfile, add File::CREAT like:
# # file = File.open('foo.log', File::WRONLY | File::APPEND | File::CREAT)
# logger = Logger.new(file)
#
# 4. Create a logger which ages the logfile once it reaches a certain size.
# Leave 10 "old" log files where each file is about 1,024,000 bytes.
#
# logger = Logger.new('foo.log', 10, 1024000)
#
# 5. Create a logger which ages the logfile daily/weekly/monthly.
#
# logger = Logger.new('foo.log', 'daily')
# logger = Logger.new('foo.log', 'weekly')
# logger = Logger.new('foo.log', 'monthly')
#
# === How to log a message
#
# Notice the different methods (+fatal+, +error+, +info+) being used to log
# messages of various levels? Other methods in this family are +warn+ and
# +debug+. +add+ is used below to log a message of an arbitrary (perhaps
# dynamic) level.
#
# 1. Message in a block.
#
# logger.fatal { "Argument 'foo' not given." }
#
# 2. Message as a string.
#
# logger.error "Argument #{@foo} mismatch."
#
# 3. With progname.
#
# logger.info('initialize') { "Initializing..." }
#
# 4. With severity.
#
# logger.add(Logger::FATAL) { 'Fatal error!' }
#
# The block form allows you to create potentially complex log messages,
# but to delay their evaluation until and unless the message is
# logged. For example, if we have the following:
#
# logger.debug { "This is a " + potentially + " expensive operation" }
#
# If the logger's level is +INFO+ or higher, no debug messages will be logged,
# and the entire block will not even be evaluated. Compare to this:
#
# logger.debug("This is a " + potentially + " expensive operation")
#
# Here, the string concatenation is done every time, even if the log
# level is not set to show the debug message.
#
# === How to close a logger
#
# logger.close
#
# === Setting severity threshold
#
# 1. Original interface.
#
# logger.sev_threshold = Logger::WARN
#
# 2. Log4r (somewhat) compatible interface.
#
# logger.level = Logger::INFO
#
# # DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN
#
# 3. Symbol or String (case insensitive)
#
# logger.level = :info
# logger.level = 'INFO'
#
# # :debug < :info < :warn < :error < :fatal < :unknown
#
# 4. Constructor
#
# Logger.new(logdev, level: Logger::INFO)
# Logger.new(logdev, level: :info)
# Logger.new(logdev, level: 'INFO')
#
# == Format
#
# Log messages are rendered in the output stream in a certain format by
# default. The default format and a sample are shown below:
#
# Log format:
# SeverityID, [DateTime #pid] SeverityLabel -- ProgName: message
#
# Log sample:
# I, [1999-03-03T02:34:24.895701 #19074] INFO -- Main: info.
#
# You may change the date and time format via #datetime_format=.
#
# logger.datetime_format = '%Y-%m-%d %H:%M:%S'
# # e.g. "2004-01-03 00:54:26"
#
# or via the constructor.
#
# Logger.new(logdev, datetime_format: '%Y-%m-%d %H:%M:%S')
#
# Or, you may change the overall format via the #formatter= method.
#
# logger.formatter = proc do |severity, datetime, progname, msg|
# "#{datetime}: #{msg}\n"
# end
# # e.g. "2005-09-22 08:51:08 +0900: hello world"
#
# or via the constructor.
#
# Logger.new(logdev, formatter: proc {|severity, datetime, progname, msg|
# "#{datetime}: #{msg}\n"
# })

#
# == Usage
#
# The following is a list of common functionalities that the debugger
# provides.
#
# === Navigating through your code
#
# In general, a debugger is used to find bugs in your program, which
# often means pausing execution and inspecting variables at some point
# in time.
#
# Let's look at an example:
#
# def my_method(foo)
# require 'debug'
# foo = get_foo if foo.nil?
# raise if foo.nil?
# end
#
# When you run this program, the debugger will kick in just before the
# +foo+ assignment.
#
# (rdb:1) p foo
# nil
#
# In this example, it'd be interesting to move to the next line and
# inspect the value of +foo+ again. You can do that by pressing +n+:
#
# (rdb:1) n # goes to next line
# (rdb:1) p foo
# nil
#
# You now know that the original value of +foo+ was nil, and that it
# still was nil after calling +get_foo+.
#
# Other useful commands for navigating through your code are:
#
# +c+::
# Runs the program until it either exists or encounters another breakpoint.
# You usually press +c+ when you are finished debugging your program and
# want to resume its execution.
# +s+::
# Steps into method definition. In the previous example, +s+ would take you
# inside the method definition of +get_foo+.
# +r+::
# Restart the program.
# +q+::
# Quit the program.
#
# === Inspecting variables
#
# You can use the debugger to easily inspect both local and global variables.
# We've seen how to inspect local variables before:
#
# (rdb:1) p my_arg
# 42
#
# You can also pretty print the result of variables or expressions:
#
# (rdb:1) pp %w{a very long long array containing many words}
# ["a",
# "very",
# "long",
# ...
# ]
#
# You can list all local variables with +v l+:
#
# (rdb:1) v l
# foo => "hello"
#
# Similarly, you can show all global variables with +v g+:
#
# (rdb:1) v g
# all global variables
#
# Finally, you can omit +p+ if you simply want to evaluate a variable or
# expression
#
# (rdb:1) 5**2
# 25
#
# === Going beyond basics
#
# Ruby Debug provides more advanced functionalities like switching
# between threads, setting breakpoints and watch expressions, and more.
# The full list of commands is available at any time by pressing +h+.
#
# == Staying out of trouble
#
# Make sure you remove every instance of +require 'debug'+ before
# shipping your code. Failing to do so may result in your program
# hanging unpredictably.
#
# Debug is not available in safe mode.

#
# Implementation of the _Observer_ object-oriented design pattern. The
# following documentation is copied, with modifications, from "Programming
# Ruby", by Hunt and Thomas; http://www.ruby-doc.org/docs/ProgrammingRuby/html/lib_patterns.html.
#
# See Observable for more info.
# The Observer pattern (also known as publish/subscribe) provides a simple
# mechanism for one object to inform a set of interested third-party objects
# when its state changes.
#
# == Mechanism
#
# The notifying class mixes in the +Observable+
# module, which provides the methods for managing the associated observer
# objects.
#
# The observable object must:
# * assert that it has +#changed+
# * call +#notify_observers+
#
# An observer subscribes to updates using Observable#add_observer, which also
# specifies the method called via #notify_observers. The default method for
# #notify_observers is #update.
#
# === Example
#
# The following example demonstrates this nicely. A +Ticker+, when run,
# continually receives the stock +Price+ for its <tt>@symbol</tt>. A +Warner+
# is a general observer of the price, and two warners are demonstrated, a
# +WarnLow+ and a +WarnHigh+, which print a warning if the price is below or
# above their set limits, respectively.
#
# The +update+ callback allows the warners to run without being explicitly
# called. The system is set up with the +Ticker+ and several observers, and the
# observers do their duty without the top-level code having to interfere.
#
# Note that the contract between publisher and subscriber (observable and
# observer) is not declared or enforced. The +Ticker+ publishes a time and a
# price, and the warners receive that. But if you don't ensure that your
# contracts are correct, nothing else can warn you.
#
# require "observer"
#
# class Ticker ### Periodically fetch a stock price.
# include Observable
#
# def initialize(symbol)
# @symbol = symbol
# end
#
# def run
# last_price = nil
# loop do
# price = Price.fetch(@symbol)
# print "Current price: #{price}\n"
# if price != last_price
# changed # notify observers
# last_price = price
# notify_observers(Time.now, price)
# end
# sleep 1
# end
# end
# end
#
# class Price ### A mock class to fetch a stock price (60 - 140).
# def self.fetch(symbol)
# 60 + rand(80)
# end
# end
#
# class Warner ### An abstract observer of Ticker objects.
# def initialize(ticker, limit)
# @limit = limit
# ticker.add_observer(self)
# end
# end
#
# class WarnLow < Warner
# def update(time, price) # callback for observer
# if price < @limit
# print "--- #{time.to_s}: Price below #@limit: #{price}\n"
# end
# end
# end
#
# class WarnHigh < Warner
# def update(time, price) # callback for observer
# if price > @limit
# print "+++ #{time.to_s}: Price above #@limit: #{price}\n"
# end
# end
# end
#
# ticker = Ticker.new("MSFT")
# WarnLow.new(ticker, 80)
# WarnHigh.new(ticker, 120)
# ticker.run
#
# Produces:
#
# Current price: 83
# Current price: 75
# --- Sun Jun 09 00:10:25 CDT 2002: Price below 80: 75
# Current price: 90
# Current price: 134
# +++ Sun Jun 09 00:10:25 CDT 2002: Price above 120: 134
# Current price: 134
# Current price: 112
# Current price: 79
# --- Sun Jun 09 00:10:25 CDT 2002: Price below 80: 79
#
# === Usage with procs
#
# The +#notify_observers+ method can also be used with +proc+s by using
# the +:call+ as +func+ parameter.
#
# The following example illustrates the use of a lambda:
#
# require 'observer'
#
# class Ticker
# include Observable
#
# def run
# # logic to retrieve the price (here 77.0)
# changed
# notify_observers(77.0)
# end
# end
#
# ticker = Ticker.new
# warner = ->(price) { puts "New price received: #{price}" }
# ticker.add_observer(warner, :call)
# ticker.run

##
# Syslog::Logger is a Logger work-alike that logs via syslog instead of to a
# file. You can use Syslog::Logger to aggregate logs between multiple
# machines.
#
# By default, Syslog::Logger uses the program name 'ruby', but this can be
# changed via the first argument to Syslog::Logger.new.
#
# NOTE! You can only set the Syslog::Logger program name when you initialize
# Syslog::Logger for the first time. This is a limitation of the way
# Syslog::Logger uses syslog (and in some ways, a limitation of the way
# syslog(3) works). Attempts to change Syslog::Logger's program name after
# the first initialization will be ignored.
#
# === Example
#
# The following will log to syslogd on your local machine:
#
# require 'syslog/logger'
#
# log = Syslog::Logger.new 'my_program'
# log.info 'this line will be logged via syslog(3)'
#
# Also the facility may be set to specify the facility level which will be used:
#
# log.info 'this line will be logged using Syslog default facility level'
#
# log_local1 = Syslog::Logger.new 'my_program', Syslog::LOG_LOCAL1
# log_local1.info 'this line will be logged using local1 facility level'
#
#
# You may need to perform some syslog.conf setup first. For a BSD machine add
# the following lines to /etc/syslog.conf:
#
# !my_program
# *.* /var/log/my_program.log
#
# Then touch /var/log/my_program.log and signal syslogd with a HUP
# (killall -HUP syslogd, on FreeBSD).
#
# If you wish to have logs automatically roll over and archive, see the
# newsyslog.conf(5) and newsyslog(8) man pages.

require 'cgi'
require 'tmpdir'
class CGI
# == Overview
#
# This file provides the CGI::Session class, which provides session
# support for CGI scripts. A session is a sequence of HTTP requests
# and responses linked together and associated with a single client.
# Information associated with the session is stored
# on the server between requests. A session id is passed between client
# and server with every request and response, transparently
# to the user. This adds state information to the otherwise stateless
# HTTP request/response protocol.
#
# == Lifecycle
#
# A CGI::Session instance is created from a CGI object. By default,
# this CGI::Session instance will start a new session if none currently
# exists, or continue the current session for this client if one does
# exist. The +new_session+ option can be used to either always or
# never create a new session. See #new() for more details.
#
# #delete() deletes a session from session storage. It
# does not however remove the session id from the client. If the client
# makes another request with the same id, the effect will be to start
# a new session with the old session's id.
#
# == Setting and retrieving session data.
#
# The Session class associates data with a session as key-value pairs.
# This data can be set and retrieved by indexing the Session instance
# using '[]', much the same as hashes (although other hash methods
# are not supported).
#
# When session processing has been completed for a request, the
# session should be closed using the close() method. This will
# store the session's state to persistent storage. If you want
# to store the session's state to persistent storage without
# finishing session processing for this request, call the update()
# method.
#
# == Storing session state
#
# The caller can specify what form of storage to use for the session's
# data with the +database_manager+ option to CGI::Session::new. The
# following storage classes are provided as part of the standard library:
#
# CGI::Session::FileStore:: stores data as plain text in a flat file. Only
# works with String data. This is the default
# storage type.
# CGI::Session::MemoryStore:: stores data in an in-memory hash. The data
# only persists for as long as the current Ruby
# interpreter instance does.
# CGI::Session::PStore:: stores data in Marshalled format. Provided by
# cgi/session/pstore.rb. Supports data of any type,
# and provides file-locking and transaction support.
#
# Custom storage types can also be created by defining a class with
# the following methods:
#
# new(session, options)
# restore # returns hash of session data.
# update
# close
# delete
#
# Changing storage type mid-session does not work. Note in particular
# that by default the FileStore and PStore session data files have the
# same name. If your application switches from one to the other without
# making sure that filenames will be different
# and clients still have old sessions lying around in cookies, then
# things will break nastily!
#
# == Maintaining the session id.
#
# Most session state is maintained on the server. However, a session
# id must be passed backwards and forwards between client and server
# to maintain a reference to this session state.
#
# The simplest way to do this is via cookies. The CGI::Session class
# provides transparent support for session id communication via cookies
# if the client has cookies enabled.
#
# If the client has cookies disabled, the session id must be included
# as a parameter of all requests sent by the client to the server. The
# CGI::Session class in conjunction with the CGI class will transparently
# add the session id as a hidden input field to all forms generated
# using the CGI#form() HTML generation method. No built-in support is
# provided for other mechanisms, such as URL re-writing. The caller is
# responsible for extracting the session id from the session_id
# attribute and manually encoding it in URLs and adding it as a hidden
# input to HTML forms created by other mechanisms. Also, session expiry
# is not automatically handled.
#
# == Examples of use
#
# === Setting the user's name
#
# require 'cgi'
# require 'cgi/session'
# require 'cgi/session/pstore' # provides CGI::Session::PStore
#
# cgi = CGI.new("html4")
#
# session = CGI::Session.new(cgi,
# 'database_manager' => CGI::Session::PStore, # use PStore
# 'session_key' => '_rb_sess_id', # custom session key
# 'session_expires' => Time.now + 30 * 60, # 30 minute timeout
# 'prefix' => 'pstore_sid_') # PStore option
# if cgi.has_key?('user_name') and cgi['user_name'] != ''
# # coerce to String: cgi[] returns the
# # string-like CGI::QueryExtension::Value
# session['user_name'] = cgi['user_name'].to_s
# elsif !session['user_name']
# session['user_name'] = "guest"
# end
# session.close
#
# === Creating a new session safely
#
# require 'cgi'
# require 'cgi/session'
#
# cgi = CGI.new("html4")
#
# # We make sure to delete an old session if one exists,
# # not just to free resources, but to prevent the session
# # from being maliciously hijacked later on.
# begin
# session = CGI::Session.new(cgi, 'new_session' => false)
# session.delete
# rescue ArgumentError # if no old session
# end

# Create a new CGI::Session object for +request+.
#
# +request+ is an instance of the +CGI+ class (see cgi.rb).
# +option+ is a hash of options for initialising this
# CGI::Session instance. The following options are
# recognised:
#
# session_key:: the parameter name used for the session id.
# Defaults to '_session_id'.
# session_id:: the session id to use. If not provided, then
# it is retrieved from the +session_key+ parameter
# of the request, or automatically generated for
# a new session.
# new_session:: if true, force creation of a new session. If not set,
# a new session is only created if none currently
# exists. If false, a new session is never created,
# and if none currently exists and the +session_id+
# option is not set, an ArgumentError is raised.
# database_manager:: the name of the class providing storage facilities
# for session state persistence. Built-in support
# is provided for +FileStore+ (the default),
# +MemoryStore+, and +PStore+ (from
# cgi/session/pstore.rb). See the documentation for
# these classes for more details.
#
# The following options are also recognised, but only apply if the
# session id is stored in a cookie.
#
# session_expires:: the time the current session expires, as a
# +Time+ object. If not set, the session will terminate
# when the user's browser is closed.
# session_domain:: the hostname domain for which this session is valid.
# If not set, defaults to the hostname of the server.
# session_secure:: if +true+, this session will only work over HTTPS.
# session_path:: the path for which this session applies. Defaults
# to the directory of the CGI script.
#
# +option+ is also passed on to the session storage class initializer; see
# the documentation for each session storage class for the options
# they support.
#
# The retrieved or created session is automatically added to +request+
# as a cookie, and also to its +output_hidden+ table, which is used
# to add hidden input elements to forms.
#
# *WARNING* the +output_hidden+
# fields are surrounded by a <fieldset> tag in HTML 4 generation, which

# :tag_maker => tag_maker }</tt> Note that it is recommended to use the
# +options_hash+ form, since it also allows you specify the charset you
# will accept.
# <tt>options_hash</tt>::
# A Hash that recognizes three options:
#
# <tt>:accept_charset</tt>::
# specifies encoding of received query string. If omitted,
# <tt>@@accept_charset</tt> is used. If the encoding is not valid, a
# CGI::InvalidEncoding will be raised.
#
# Example. Suppose <tt>@@accept_charset</tt> is "UTF-8"
#
# when not specified:
#
# cgi=CGI.new # @accept_charset # => "UTF-8"
#
# when specified as "EUC-JP":
#
# cgi=CGI.new(:accept_charset => "EUC-JP") # => "EUC-JP"
#
# <tt>:tag_maker</tt>::
# String that specifies which version of the HTML generation methods to
# use. If not specified, no HTML generation methods will be loaded.
#
# The following values are supported:
#
# "html3":: HTML 3.x
# "html4":: HTML 4.0
# "html4Tr":: HTML 4.0 Transitional
# "html4Fr":: HTML 4.0 with Framesets
# "html5":: HTML 5
#
# <tt>:max_multipart_length</tt>::
# Specifies maximum length of multipart data. Can be an Integer scalar or
# a lambda, that will be evaluated when the request is parsed. This
# allows more complex logic to be set when determining whether to accept
# multipart data (e.g. consult a registered users upload allowance)
#
# Default is 128 * 1024 * 1024 bytes
#
# cgi=CGI.new(:max_multipart_length => 268435456) # simple scalar
#
# cgi=CGI.new(:max_multipart_length => -> {check_filesystem}) # lambda
#
# <tt>block</tt>::
# If provided, the block is called when an invalid encoding is
# encountered. For example:
#
# encoding_errors={}
# cgi=CGI.new(:accept_charset=>"EUC-JP") do |name,value|
# encoding_errors[name] = value
# end
#
# Finally, if the CGI object is not created in a standard CGI call
# environment (that is, it can't locate REQUEST_METHOD in its environment),
# then it will run in "offline" mode. In this mode, it reads its parameters
# from the command line or (failing that) from standard input. Otherwise,
# cookies and other parameters are parsed automatically from the standard
# CGI locations, which varies according to the REQUEST_METHOD.

require 'json/common'
##
# = JavaScript \Object Notation (\JSON)
#
# \JSON is a lightweight data-interchange format.
#
# A \JSON value is one of the following:
# - Double-quoted text: <tt>"foo"</tt>.
# - Number: +1+, +1.0+, +2.0e2+.
# - Boolean: +true+, +false+.
# - Null: +null+.
# - \Array: an ordered list of values, enclosed by square brackets:
# ["foo", 1, 1.0, 2.0e2, true, false, null]
#
# - \Object: a collection of name/value pairs, enclosed by curly braces;
# each name is double-quoted text;
# the values may be any \JSON values:
# {"a": "foo", "b": 1, "c": 1.0, "d": 2.0e2, "e": true, "f": false, "g": null}
#
# A \JSON array or object may contain nested arrays, objects, and scalars
# to any depth:
# {"foo": {"bar": 1, "baz": 2}, "bat": [0, 1, 2]}
# [{"foo": 0, "bar": 1}, ["baz", 2]]
#
# == Using \Module \JSON
#
# To make module \JSON available in your code, begin with:
# require 'json'
#
# All examples here assume that this has been done.
#
# === Parsing \JSON
#
# You can parse a \String containing \JSON data using
# either of two methods:
# - <tt>JSON.parse(source, opts)</tt>
# - <tt>JSON.parse!(source, opts)</tt>
#
# where
# - +source+ is a Ruby object.
# - +opts+ is a \Hash object containing options
# that control both input allowed and output formatting.
#
# The difference between the two methods
# is that JSON.parse! omits some checks
# and may not be safe for some +source+ data;
# use it only for data from trusted sources.
# Use the safer method JSON.parse for less trusted sources.
#
# ==== Parsing \JSON Arrays
#
# When +source+ is a \JSON array, JSON.parse by default returns a Ruby \Array:
# json = '["foo", 1, 1.0, 2.0e2, true, false, null]'
# ruby = JSON.parse(json)
# ruby # => ["foo", 1, 1.0, 200.0, true, false, nil]
# ruby.class # => Array
#
# The \JSON array may contain nested arrays, objects, and scalars
# to any depth:
# json = '[{"foo": 0, "bar": 1}, ["baz", 2]]'
# JSON.parse(json) # => [{"foo"=>0, "bar"=>1}, ["baz", 2]]
#
# ==== Parsing \JSON \Objects
#
# When the source is a \JSON object, JSON.parse by default returns a Ruby \Hash:
# json = '{"a": "foo", "b": 1, "c": 1.0, "d": 2.0e2, "e": true, "f": false, "g": null}'
# ruby = JSON.parse(json)
# ruby # => {"a"=>"foo", "b"=>1, "c"=>1.0, "d"=>200.0, "e"=>true, "f"=>false, "g"=>nil}
# ruby.class # => Hash
#
# The \JSON object may contain nested arrays, objects, and scalars
# to any depth:
# json = '{"foo": {"bar": 1, "baz": 2}, "bat": [0, 1, 2]}'
# JSON.parse(json) # => {"foo"=>{"bar"=>1, "baz"=>2}, "bat"=>[0, 1, 2]}
#
# ==== Parsing \JSON Scalars
#
# When the source is a \JSON scalar (not an array or object),
# JSON.parse returns a Ruby scalar.
#
# \String:
# ruby = JSON.parse('"foo"')
# ruby # => 'foo'
# ruby.class # => String
# \Integer:
# ruby = JSON.parse('1')
# ruby # => 1
# ruby.class # => Integer
# \Float:
# ruby = JSON.parse('1.0')
# ruby # => 1.0
# ruby.class # => Float
# ruby = JSON.parse('2.0e2')
# ruby # => 200
# ruby.class # => Float
# Boolean:
# ruby = JSON.parse('true')
# ruby # => true
# ruby.class # => TrueClass
# ruby = JSON.parse('false')
# ruby # => false
# ruby.class # => FalseClass
# Null:
# ruby = JSON.parse('null')
# ruby # => nil
# ruby.class # => NilClass
#
# ==== Parsing Options
#
# ====== Input Options
#
# Option +max_nesting+ (\Integer) specifies the maximum nesting depth allowed;
# defaults to +100+; specify +false+ to disable depth checking.
#
# With the default, +false+:
# source = '[0, [1, [2, [3]]]]'
# ruby = JSON.parse(source)
# ruby # => [0, [1, [2, [3]]]]
# Too deep:
# # Raises JSON::NestingError (nesting of 2 is too deep):
# JSON.parse(source, {max_nesting: 1})
# Bad value:
# # Raises TypeError (wrong argument type Symbol (expected Fixnum)):
# JSON.parse(source, {max_nesting: :foo})
#
# ---
#
# Option +allow_nan+ (boolean) specifies whether to allow
# NaN, Infinity, and MinusInfinity in +source+;
# defaults to +false+.
#
# With the default, +false+:
# # Raises JSON::ParserError (225: unexpected token at '[NaN]'):
# JSON.parse('[NaN]')
# # Raises JSON::ParserError (232: unexpected token at '[Infinity]'):
# JSON.parse('[Infinity]')
# # Raises JSON::ParserError (248: unexpected token at '[-Infinity]'):
# JSON.parse('[-Infinity]')
# Allow:
# source = '[NaN, Infinity, -Infinity]'
# ruby = JSON.parse(source, {allow_nan: true})
# ruby # => [NaN, Infinity, -Infinity]
#
# ====== Output Options
#
# Option +symbolize_names+ (boolean) specifies whether returned \Hash keys
# should be Symbols;
# defaults to +false+ (use Strings).
#
# With the default, +false+:
# source = '{"a": "foo", "b": 1.0, "c": true, "d": false, "e": null}'
# ruby = JSON.parse(source)
# ruby # => {"a"=>"foo", "b"=>1.0, "c"=>true, "d"=>false, "e"=>nil}
# Use Symbols:
# ruby = JSON.parse(source, {symbolize_names: true})
# ruby # => {:a=>"foo", :b=>1.0, :c=>true, :d=>false, :e=>nil}
#
# ---
#
# Option +object_class+ (\Class) specifies the Ruby class to be used
# for each \JSON object;
# defaults to \Hash.
#
# With the default, \Hash:
# source = '{"a": "foo", "b": 1.0, "c": true, "d": false, "e": null}'
# ruby = JSON.parse(source)
# ruby.class # => Hash
# Use class \OpenStruct:
# ruby = JSON.parse(source, {object_class: OpenStruct})
# ruby # => #<OpenStruct a="foo", b=1.0, c=true, d=false, e=nil>
#
# ---
#
# Option +array_class+ (\Class) specifies the Ruby class to be used
# for each \JSON array;
# defaults to \Array.
#
# With the default, \Array:
# source = '["foo", 1.0, true, false, null]'
# ruby = JSON.parse(source)
# ruby.class # => Array
# Use class \Set:
# ruby = JSON.parse(source, {array_class: Set})
# ruby # => #<Set: {"foo", 1.0, true, false, nil}>
#
# ---
#
# Option +create_additions+ (boolean) specifies whether to use \JSON additions in parsing.
# See {\JSON Additions}[#module-JSON-label-JSON+Additions].
#
# === Generating \JSON
#
# To generate a Ruby \String containing \JSON data,
# use method <tt>JSON.generate(source, opts)</tt>, where
# - +source+ is a Ruby object.
# - +opts+ is a \Hash object containing options
# that control both input allowed and output formatting.
#
# ==== Generating \JSON from Arrays
#
# When the source is a Ruby \Array, JSON.generate returns
# a \String containing a \JSON array:
# ruby = [0, 's', :foo]
# json = JSON.generate(ruby)
# json # => '[0,"s","foo"]'
#
# The Ruby \Array array may contain nested arrays, hashes, and scalars
# to any depth:
# ruby = [0, [1, 2], {foo: 3, bar: 4}]
# json = JSON.generate(ruby)
# json # => '[0,[1,2],{"foo":3,"bar":4}]'
#
# ==== Generating \JSON from Hashes
#
# When the source is a Ruby \Hash, JSON.generate returns
# a \String containing a \JSON object:
# ruby = {foo: 0, bar: 's', baz: :bat}
# json = JSON.generate(ruby)
# json # => '{"foo":0,"bar":"s","baz":"bat"}'
#
# The Ruby \Hash array may contain nested arrays, hashes, and scalars
# to any depth:
# ruby = {foo: [0, 1], bar: {baz: 2, bat: 3}, bam: :bad}
# json = JSON.generate(ruby)
# json # => '{"foo":[0,1],"bar":{"baz":2,"bat":3},"bam":"bad"}'
#
# ==== Generating \JSON from Other Objects
#
# When the source is neither an \Array nor a \Hash,
# the generated \JSON data depends on the class of the source.
#
# When the source is a Ruby \Integer or \Float, JSON.generate returns
# a \String containing a \JSON number:
# JSON.generate(42) # => '42'
# JSON.generate(0.42) # => '0.42'
#
# When the source is a Ruby \String, JSON.generate returns
# a \String containing a \JSON string (with double-quotes):
# JSON.generate('A string') # => '"A string"'
#
# When the source is +true+, +false+ or +nil+, JSON.generate returns
# a \String containing the corresponding \JSON token:
# JSON.generate(true) # => 'true'
# JSON.generate(false) # => 'false'
# JSON.generate(nil) # => 'null'
#
# When the source is none of the above, JSON.generate returns
# a \String containing a \JSON string representation of the source:
# JSON.generate(:foo) # => '"foo"'
# JSON.generate(Complex(0, 0)) # => '"0+0i"'
# JSON.generate(Dir.new('.')) # => '"#<Dir>"'
#
# ==== Generating Options
#
# ====== Input Options
#
# Option +allow_nan+ (boolean) specifies whether
# +NaN+, +Infinity+, and <tt>-Infinity</tt> may be generated;
# defaults to +false+.
#
# With the default, +false+:
# # Raises JSON::GeneratorError (920: NaN not allowed in JSON):
# JSON.generate(JSON::NaN)
# # Raises JSON::GeneratorError (917: Infinity not allowed in JSON):
# JSON.generate(JSON::Infinity)
# # Raises JSON::GeneratorError (917: -Infinity not allowed in JSON):
# JSON.generate(JSON::MinusInfinity)
#
# Allow:
# ruby = [Float::NaN, Float::Infinity, Float::MinusInfinity]
# JSON.generate(ruby, allow_nan: true) # => '[NaN,Infinity,-Infinity]'
#
# ---
#
# Option +max_nesting+ (\Integer) specifies the maximum nesting depth
# in +obj+; defaults to +100+.
#
# With the default, +100+:
# obj = [[[[[[0]]]]]]
# JSON.generate(obj) # => '[[[[[[0]]]]]]'
#
# Too deep:
# # Raises JSON::NestingError (nesting of 2 is too deep):
# JSON.generate(obj, max_nesting: 2)
#
# ====== Output Options
#
# The default formatting options generate the most compact
# \JSON data, all on one line and with no whitespace.
#
# You can use these formatting options to generate
# \JSON data in a more open format, using whitespace.
# See also JSON.pretty_generate.
#
# - Option +array_nl+ (\String) specifies a string (usually a newline)
# to be inserted after each \JSON array; defaults to the empty \String, <tt>''</tt>.
# - Option +object_nl+ (\String) specifies a string (usually a newline)
# to be inserted after each \JSON object; defaults to the empty \String, <tt>''</tt>.
# - Option +indent+ (\String) specifies the string (usually spaces) to be
# used for indentation; defaults to the empty \String, <tt>''</tt>;
# defaults to the empty \String, <tt>''</tt>;
# has no effect unless options +array_nl+ or +object_nl+ specify newlines.
# - Option +space+ (\String) specifies a string (usually a space) to be
# inserted after the colon in each \JSON object's pair;
# defaults to the empty \String, <tt>''</tt>.
# - Option +space_before+ (\String) specifies a string (usually a space) to be
# inserted before the colon in each \JSON object's pair;
# defaults to the empty \String, <tt>''</tt>.
#
# In this example, +obj+ is used first to generate the shortest
# \JSON data (no whitespace), then again with all formatting options
# specified:
#
# obj = {foo: [:bar, :baz], bat: {bam: 0, bad: 1}}
# json = JSON.generate(obj)
# puts 'Compact:', json
# opts = {
# array_nl: "\n",
# object_nl: "\n",
# indent: ' ',
# space_before: ' ',
# space: ' '
# }
# puts 'Open:', JSON.generate(obj, opts)
#
# Output:
# Compact:
# {"foo":["bar","baz"],"bat":{"bam":0,"bad":1}}
# Open:
# {
# "foo" : [
# "bar",
# "baz"
# ],
# "bat" : {
# "bam" : 0,
# "bad" : 1
# }
# }
#
# == \JSON Additions
#
# When you "round trip" a non-\String object from Ruby to \JSON and back,
# you have a new \String, instead of the object you began with:
# ruby0 = Range.new(0, 2)
# json = JSON.generate(ruby0)
# json # => '0..2"'
# ruby1 = JSON.parse(json)
# ruby1 # => '0..2'
# ruby1.class # => String
#
# You can use \JSON _additions_ to preserve the original object.
# The addition is an extension of a ruby class, so that:
# - \JSON.generate stores more information in the \JSON string.
# - \JSON.parse, called with option +create_additions+,
# uses that information to create a proper Ruby object.
#
# This example shows a \Range being generated into \JSON
# and parsed back into Ruby, both without and with
# the addition for \Range:
# ruby = Range.new(0, 2)
# # This passage does not use the addition for Range.
# json0 = JSON.generate(ruby)
# ruby0 = JSON.parse(json0)
# # This passage uses the addition for Range.
# require 'json/add/range'
# json1 = JSON.generate(ruby)
# ruby1 = JSON.parse(json1, create_additions: true)
# # Make a nice display.
# display = <<EOT
# Generated JSON:
# Without addition: #{json0} (#{json0.class})
# With addition: #{json1} (#{json1.class})
# Parsed JSON:
# Without addition: #{ruby0.inspect} (#{ruby0.class})
# With addition: #{ruby1.inspect} (#{ruby1.class})
# EOT
# puts display
#
# This output shows the different results:
# Generated JSON:
# Without addition: "0..2" (String)
# With addition: {"json_class":"Range","a":[0,2,false]} (String)
# Parsed JSON:
# Without addition: "0..2" (String)
# With addition: 0..2 (Range)
#
# The \JSON module includes additions for certain classes.
# You can also craft custom additions.
# See {Custom \JSON Additions}[#module-JSON-label-Custom+JSON+Additions].
#
# === Built-in Additions
#
# The \JSON module includes additions for certain classes.
# To use an addition, +require+ its source:
# - BigDecimal: <tt>require 'json/add/bigdecimal'</tt>
# - Complex: <tt>require 'json/add/complex'</tt>
# - Date: <tt>require 'json/add/date'</tt>
# - DateTime: <tt>require 'json/add/date_time'</tt>

#
# === Custom \JSON Additions
#
# In addition to the \JSON additions provided,
# you can craft \JSON additions of your own,
# either for Ruby built-in classes or for user-defined classes.
#
# Here's a user-defined class +Foo+:
# class Foo
# attr_accessor :bar, :baz
# def initialize(bar, baz)
# self.bar = bar
# self.baz = baz
# end
# end
#
# Here's the \JSON addition for it:
# # Extend class Foo with JSON addition.
# class Foo
# # Serialize Foo object with its class name and arguments
# def to_json(*args)
# {
# JSON.create_id => self.class.name,
# 'a' => [ bar, baz ]
# }.to_json(*args)
# end
# # Deserialize JSON string by constructing new Foo object with arguments.
# def self.json_create(object)
# new(*object['a'])
# end
# end
#
# Demonstration:
# require 'json'
# # This Foo object has no custom addition.
# foo0 = Foo.new(0, 1)
# json0 = JSON.generate(foo0)
# obj0 = JSON.parse(json0)
# # Lood the custom addition.
# require_relative 'foo_addition'
# # This foo has the custom addition.
# foo1 = Foo.new(0, 1)
# json1 = JSON.generate(foo1)
# obj1 = JSON.parse(json1, create_additions: true)
# # Make a nice display.
# display = <<EOT
# Generated JSON:
# Without custom addition: #{json0} (#{json0.class})
# With custom addition: #{json1} (#{json1.class})
# Parsed JSON:
# Without custom addition: #{obj0.inspect} (#{obj0.class})
# With custom addition: #{obj1.inspect} (#{obj1.class})
# EOT
# puts display
#
# Output:
#
# Generated JSON:
# Without custom addition: "#<Foo:0x0000000006534e80>" (String)
# With custom addition: {"json_class":"Foo","a":[0,1]} (String)
# Parsed JSON:
# Without custom addition: "#<Foo:0x0000000006534e80>" (String)

#
# This class implements a pretty printing algorithm. It finds line breaks and
# nice indentations for grouped structure.
#
# By default, the class assumes that primitive elements are strings and each
# byte in the strings have single column in width. But it can be used for
# other situations by giving suitable arguments for some methods:
# * newline object and space generation block for PrettyPrint.new
# * optional width argument for PrettyPrint#text
# * PrettyPrint#breakable
#
# There are several candidate uses:
# * text formatting using proportional fonts
# * multibyte characters which has columns different to number of bytes
# * non-string formatting
#
# == Bugs
# * Box based formatting?
# * Other (better) model/algorithm?

class PrettyPrint

end
# This is similar to PrettyPrint::format but the result has no breaks.

# +maxwidth+, +newline+ and +genspace+ are ignored.

# The invocation of +breakable+ in the block doesn't break a line and is
# treated as just an invocation of +text+.

#
# +output+ is an output target. If it is not specified, '' is assumed. It
# should have a << method which accepts the first argument +obj+ of
# PrettyPrint#text, the first argument +sep+ of PrettyPrint#breakable, the
# first argument +newline+ of PrettyPrint.new, and the result of a given
# block for PrettyPrint.new.
#
# +maxwidth+ specifies maximum line length. If it is not specified, 79 is
# assumed. However actual outputs may overflow +maxwidth+ if long
# non-breakable texts are provided.
#
# +newline+ is used for line breaks. "\n" is used if it is not specified.
#
# The block is used to generate spaces. {|width| ' ' * width} is used if it
# is not given.

#
# It does this by registering an event handler with Kernel#set_trace_func for
# processing incoming events. It also provides methods for filtering unwanted
# trace output (see Tracer.add_filter, Tracer.on, and Tracer.off).
#
# == Example
#
# Consider the following Ruby script
#
# class A
# def square(a)
# return a*a
# end
# end
#
# a = A.new
# a.square(5)
#
# Running the above script using <code>ruby -r tracer example.rb</code> will
# output the following trace to STDOUT (Note you can also explicitly
# <code>require 'tracer'</code>)
#
# #0:<internal:lib/rubygems/custom_require>:38:Kernel:<: -
# #0:example.rb:3::-: class A
# #0:example.rb:3::C: class A

# = base64.rb: methods for base64-encoding and -decoding strings
#
# The Base64 module provides for the encoding (#encode64, #strict_encode64,
# #urlsafe_encode64) and decoding (#decode64, #strict_decode64,
# #urlsafe_decode64) of binary data using a Base64 representation.
#
# == Example
#
# A simple encoding and decoding.
#
# require "base64"
#
# enc = Base64.encode64('Send reinforcements')
# # -> "U2VuZCByZWluZm9yY2VtZW50cw==\n"
# plain = Base64.decode64(enc)
# # -> "Send reinforcements"
#
# The purpose of using base64 to encode data is that it translates any
# binary data into purely printable characters.

#
# == Disabling +did_you_mean+
#
# Occasionally, you may want to disable the +did_you_mean+ gem for e.g.
# debugging issues in the error object itself. You can disable it entirely by
# specifying +--disable-did_you_mean+ option to the +ruby+ command:
#
# $ ruby --disable-did_you_mean -e "1.zeor?"
# -e:1:in `<main>': undefined method `zeor?' for 1:Integer (NameError)
#
# When you do not have direct access to the +ruby+ command (e.g.
# +rails console+, +irb+), you could applyoptions using the +RUBYOPT+
# environment variable:
#
# $ RUBYOPT='--disable-did_you_mean' irb
# irb:0> 1.zeor?
# # => NoMethodError (undefined method `zeor?' for 1:Integer)
#
#
# == Getting the original error message
#
# Sometimes, you do not want to disable the gem entirely, but need to get the
# original error message without suggestions (e.g. testing). In this case, you
# could use the +#original_message+ method on the error object:
#
# no_method_error = begin
# 1.zeor?
# rescue NoMethodError => error
# error
# end
#
# no_method_error.message
# # => NoMethodError (undefined method `zeor?' for 1:Integer)
# # Did you mean? zero?
#
# no_method_error.original_message
# # => NoMethodError (undefined method `zeor?' for 1:Integer)

# == Secure random number generator interface.
#
# This library is an interface to secure random number generators which are
# suitable for generating session keys in HTTP cookies, etc.
#
# You can use this library in your application by requiring it:
#
# require 'securerandom'
#
# It supports the following secure random number generators:
#
# * openssl
# * /dev/urandom
# * Win32
#
# SecureRandom is extended by the Random::Formatter module which
# defines the following methods:
#
# * alphanumeric
# * base64
# * choose
# * gen_random
# * hex
# * rand
# * random_bytes
# * random_number
# * urlsafe_base64
# * uuid
#
# These methods are usable as class methods of SecureRandom such as
# `SecureRandom.hex`.
#
# === Examples
#
# Generate random hexadecimal strings:
#
# require 'securerandom'
#
# SecureRandom.hex(10) #=> "52750b30ffbc7de3b362"
# SecureRandom.hex(10) #=> "92b15d6c8dc4beb5f559"
# SecureRandom.hex(13) #=> "39b290146bea6ce975c37cfc23"
#
# Generate random base64 strings:
#
# SecureRandom.base64(10) #=> "EcmTPZwWRAozdA=="
# SecureRandom.base64(10) #=> "KO1nIU+p9DKxGg=="
# SecureRandom.base64(12) #=> "7kJSM/MzBJI+75j8"
#
# Generate random binary strings:
#
# SecureRandom.random_bytes(10) #=> "\016\t{\370g\310pbr\301"
# SecureRandom.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"
#
# Generate alphanumeric strings:
#
# SecureRandom.alphanumeric(10) #=> "S8baxMJnPl"
# SecureRandom.alphanumeric(10) #=> "aOxAg8BAJe"
#
# Generate UUIDs:
#
# SecureRandom.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594"
# SecureRandom.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"

# OpenURI is an easy-to-use wrapper for Net::HTTP, Net::HTTPS and Net::FTP.
#
# == Example
#
# It is possible to open an http, https or ftp URL as though it were a file:
#
# URI.open("http://www.ruby-lang.org/") {|f|
# f.each_line {|line| p line}
# }
#
# The opened file has several getter methods for its meta-information, as
# follows, since it is extended by OpenURI::Meta.
#
# URI.open("http://www.ruby-lang.org/en") {|f|
# f.each_line {|line| p line}
# p f.base_uri # <URI::HTTP:0x40e6ef2 URL:http://www.ruby-lang.org/en/>
# p f.content_type # "text/html"
# p f.charset # "iso-8859-1"
# p f.content_encoding # []
# p f.last_modified # Thu Dec 05 02:45:02 UTC 2002
# }
#
# Additional header fields can be specified by an optional hash argument.
#
# URI.open("http://www.ruby-lang.org/en/",
# "User-Agent" => "Ruby/#{RUBY_VERSION}",
# "From" => "foo@bar.invalid",
# "Referer" => "http://www.ruby-lang.org/") {|f|
# # ...
# }
#
# The environment variables such as http_proxy, https_proxy and ftp_proxy
# are in effect by default. Here we disable proxy:
#
# URI.open("http://www.ruby-lang.org/en/", :proxy => nil) {|f|
# # ...
# }
#
# See OpenURI::OpenRead.open and URI.open for more on available options.
#
# URI objects can be opened in a similar way.
#
# uri = URI.parse("http://www.ruby-lang.org/en/")
# uri.open {|f|
# # ...
# }
#
# URI objects can be read directly. The returned string is also extended by
# OpenURI::Meta.

module OpenRead
# OpenURI::OpenRead#open provides `open' for URI::HTTP and URI::FTP.
#
# OpenURI::OpenRead#open takes optional 3 arguments as:
#
# OpenURI::OpenRead#open([mode [, perm]] [, options]) [{|io| ... }]
#
# OpenURI::OpenRead#open returns an IO-like object if block is not given.
# Otherwise it yields the IO object and return the value of the block.
# The IO object is extended with OpenURI::Meta.
#
# +mode+ and +perm+ are the same as Kernel#open.
#
# However, +mode+ must be read mode because OpenURI::OpenRead#open doesn't
# support write mode (yet).
# Also +perm+ is ignored because it is meaningful only for file creation.
#
# +options+ must be a hash.
#
# Each option with a string key specifies an extra header field for HTTP.
# I.e., it is ignored for FTP without HTTP proxy.
#
# The hash may include other options, where keys are symbols:
#
# [:proxy]
# Synopsis:
# :proxy => "http://proxy.foo.com:8000/"
# :proxy => URI.parse("http://proxy.foo.com:8000/")
# :proxy => true
# :proxy => false
# :proxy => nil
#
# If :proxy option is specified, the value should be String, URI,
# boolean or nil.
#
# When String or URI is given, it is treated as proxy URI.
#
# When true is given or the option itself is not specified,
# environment variable `scheme_proxy' is examined.
# `scheme' is replaced by `http', `https' or `ftp'.
#
# When false or nil is given, the environment variables are ignored and
# connection will be made to a server directly.
#
# [:proxy_http_basic_authentication]
# Synopsis:
# :proxy_http_basic_authentication =>
# ["http://proxy.foo.com:8000/", "proxy-user", "proxy-password"]
# :proxy_http_basic_authentication =>
# [URI.parse("http://proxy.foo.com:8000/"),
# "proxy-user", "proxy-password"]
#
# If :proxy option is specified, the value should be an Array with 3
# elements. It should contain a proxy URI, a proxy user name and a proxy
# password. The proxy URI should be a String, an URI or nil. The proxy
# user name and password should be a String.
#
# If nil is given for the proxy URI, this option is just ignored.
#
# If :proxy and :proxy_http_basic_authentication is specified,
# ArgumentError is raised.
#
# [:http_basic_authentication]
# Synopsis:
# :http_basic_authentication=>[user, password]
#
# If :http_basic_authentication is specified,
# the value should be an array which contains 2 strings:
# username and password.
# It is used for HTTP Basic authentication defined by RFC 2617.
#
# [:content_length_proc]
# Synopsis:
# :content_length_proc => lambda {|content_length| ... }
#
# If :content_length_proc option is specified, the option value procedure
# is called before actual transfer is started.
# It takes one argument, which is expected content length in bytes.
#
# If two or more transfers are performed by HTTP redirection, the
# procedure is called only once for the last transfer.
#
# When expected content length is unknown, the procedure is called with
# nil. This happens when the HTTP response has no Content-Length header.
#
# [:progress_proc]
# Synopsis:
# :progress_proc => lambda {|size| ...}
#
# If :progress_proc option is specified, the proc is called with one
# argument each time when `open' gets content fragment from network.
# The argument +size+ is the accumulated transferred size in bytes.
#
# If two or more transfer is done by HTTP redirection, the procedure
# is called only one for a last transfer.
#
# :progress_proc and :content_length_proc are intended to be used for
# progress bar.
# For example, it can be implemented as follows using Ruby/ProgressBar.
#
# pbar = nil
# open("http://...",
# :content_length_proc => lambda {|t|
# if t && 0 < t
# pbar = ProgressBar.new("...", t)
# pbar.file_transfer_mode
# end
# },
# :progress_proc => lambda {|s|
# pbar.set s if pbar
# }) {|f| ... }
#
# [:read_timeout]
# Synopsis:
# :read_timeout=>nil (no timeout)
# :read_timeout=>10 (10 second)
#
# :read_timeout option specifies a timeout of read for http connections.
#
# [:open_timeout]
# Synopsis:
# :open_timeout=>nil (no timeout)
# :open_timeout=>10 (10 second)
#
# :open_timeout option specifies a timeout of open for http connections.
#
# [:ssl_ca_cert]
# Synopsis:
# :ssl_ca_cert=>filename or an Array of filenames
#
# :ssl_ca_cert is used to specify CA certificate for SSL.
# If it is given, default certificates are not used.
#
# [:ssl_verify_mode]
# Synopsis:
# :ssl_verify_mode=>mode
#
# :ssl_verify_mode is used to specify openssl verify mode.
#
# [:ftp_active_mode]
# Synopsis:
# :ftp_active_mode=>bool
#
# <tt>:ftp_active_mode => true</tt> is used to make ftp active mode.
# Ruby 1.9 uses passive mode by default.
# Note that the active mode is default in Ruby 1.8 or prior.
#
# [:redirect]
# Synopsis:
# :redirect=>bool
#
# +:redirect+ is true by default. <tt>:redirect => false</tt> is used to
# disable all HTTP redirects.
#
# OpenURI::HTTPRedirect exception raised on redirection.
# Using +true+ also means that redirections between http and ftp are
# permitted.

# == Retrieving the instance
#

#
# == Generators
#
# A "generator" provides an implementation of enumerating pseudo-prime
# numbers and it remembers the position of enumeration and upper bound.
# Furthermore, it is an external iterator of prime enumeration which is
# compatible with an Enumerator.
#
# +Prime+::+PseudoPrimeGenerator+ is the base class for generators.
# There are few implementations of generator.
#
# [+Prime+::+EratosthenesGenerator+]
# Uses Eratosthenes' sieve.
# [+Prime+::+TrialDivisionGenerator+]
# Uses the trial division method.
# [+Prime+::+Generator23+]
# Generates all positive integers which are not divisible by either 2 or 3.
# This sequence is very bad as a pseudo-prime sequence. But this
# is faster and uses much less memory than the other generators. So,
# it is suitable for factorizing an integer which is not large but
# has many prime factors. e.g. for Prime#prime? .

#
#
# In concurrent programming, a monitor is an object or module intended to be
# used safely by more than one thread. The defining characteristic of a
# monitor is that its methods are executed with mutual exclusion. That is, at
# each point in time, at most one thread may be executing any of its methods.
# This mutual exclusion greatly simplifies reasoning about the implementation
# of monitors compared to reasoning about parallel code that updates a data
# structure.
#
# You can read more about the general principles on the Wikipedia page for
# Monitors[https://en.wikipedia.org/wiki/Monitor_%28synchronization%29]
#
# == Examples
#
# === Simple object.extend
#
# require 'monitor.rb'
#
# buf = []
# buf.extend(MonitorMixin)
# empty_cond = buf.new_cond
#
# # consumer
# Thread.start do
# loop do
# buf.synchronize do
# empty_cond.wait_while { buf.empty? }
# print buf.shift
# end
# end
# end
#
# # producer
# while line = ARGF.gets
# buf.synchronize do
# buf.push(line)
# empty_cond.signal
# end
# end
#
# The consumer thread waits for the producer thread to push a line to buf
# while <tt>buf.empty?</tt>. The producer thread (main thread) reads a
# line from ARGF and pushes it into buf then calls <tt>empty_cond.signal</tt>
# to notify the consumer thread of new data.
#
# === Simple Class include
#
# require 'monitor'
#
# class SynchronizedArray < Array
#
# include MonitorMixin
#
# def initialize(*args)
# super(*args)
# end
#
# alias :old_shift :shift
# alias :old_unshift :unshift
#
# def shift(n=1)
# self.synchronize do
# self.old_shift(n)
# end
# end
#
# def unshift(item)
# self.synchronize do
# self.old_unshift(item)
# end
# end
#
# # other methods ...
# end
#
# +SynchronizedArray+ implements an Array with synchronized access to items.
# This Class is implemented as subclass of Array which includes the
# MonitorMixin module.
#
require 'monitor.so'
module MonitorMixin
#
# FIXME: This isn't documented in Nutshell.
#
# Since MonitorMixin.new_cond returns a ConditionVariable, and the example
# above calls while_wait and signal, this class should be documented.
#
class ConditionVariable
#
# Releases the lock held in the associated monitor and waits; reacquires the lock on wakeup.
#
# If +timeout+ is given, this method returns after +timeout+ seconds passed,
# even if no other thread doesn't signal.
#
def wait(timeout = nil)

# Documentation comments:
# - All documentation comes from Nutshell.
# - MonitorMixin.new_cond appears in the example, but is not documented in
# Nutshell.
# - All the internals (internal modules Accessible and Initializable, class
# ConditionVariable) appear in RDoc. It might be good to hide them, by
# making them private, or marking them :nodoc:, etc.
# - RDoc doesn't recognise aliases, so we have mon_synchronize documented, but
# not synchronize.
# - mon_owner is in Nutshell, but appears as an accessor in a separate module
# here, so is hard/impossible to RDoc. Some other useful accessors
# (mon_count and some queue stuff) are also in this module, and don't appear
# directly in the RDoc output.
# - in short, it may be worth changing the code layout in this file to make the
# documentation easier

# This library provides the Set class, which deals with a collection
# of unordered values with no duplicates. It is a hybrid of Array's
# intuitive inter-operation facilities and Hash's fast lookup.
#
# The method `to_set` is added to Enumerable for convenience.
#
# Set implements a collection of unordered values with no duplicates.
# This is a hybrid of Array's intuitive inter-operation facilities and
# Hash's fast lookup.
#
# Set is easy to use with Enumerable objects (implementing `each`).
# Most of the initializer methods and binary operators accept generic
# Enumerable objects besides sets and arrays. An Enumerable object
# can be converted to Set using the `to_set` method.
#
# Set uses Hash as storage, so you must note the following points:
#
# * Equality of elements is determined according to Object#eql? and
# Object#hash. Use Set#compare_by_identity to make a set compare
# its elements by their identity.
# * Set assumes that the identity of each element does not change
# while it is stored. Modifying an element of a set will render the
# set to an unreliable state.
# * When a string is to be stored, a frozen copy of the string is
# stored instead unless the original string is already frozen.
#
# ## Comparison
#
# The comparison operators `<`, `>`, `<=`, and `>=` are implemented as
# shorthand for the {proper_,}{subset?,superset?} methods. The `<=>`
# operator reflects this order, or return `nil` for sets that both
# have distinct elements (`{x, y}` vs. `{x, z}` for example).
#
# ## Example
#
# ```ruby
# require 'set'
# s1 = Set[1, 2] #=> #<Set: {1, 2}>
# s2 = [1, 2].to_set #=> #<Set: {1, 2}>
# s1 == s2 #=> true
# s1.add("foo") #=> #<Set: {1, 2, "foo"}>
# s1.merge([2, 6]) #=> #<Set: {1, 2, "foo", 6}>
# s1.subset?(s2) #=> false
# s2.subset?(s1) #=> true
# ```

#
# A meta digest provider class for SHA256, SHA384 and SHA512.
#
# FIPS 180-2 describes SHA2 family of digest algorithms. It defines
# three algorithms:
# * one which works on chunks of 512 bits and returns a 256-bit
# digest (SHA256),
# * one which works on chunks of 1024 bits and returns a 384-bit
# digest (SHA384),
# * and one which works on chunks of 1024 bits and returns a 512-bit
# digest (SHA512).
#
# ==Examples
# require 'digest'
#
# # Compute a complete digest
# Digest::SHA2.hexdigest 'abc' # => "ba7816bf8..."
# Digest::SHA2.new(256).hexdigest 'abc' # => "ba7816bf8..."
# Digest::SHA256.hexdigest 'abc' # => "ba7816bf8..."
#
# Digest::SHA2.new(384).hexdigest 'abc' # => "cb00753f4..."
# Digest::SHA384.hexdigest 'abc' # => "cb00753f4..."
#
# Digest::SHA2.new(512).hexdigest 'abc' # => "ddaf35a19..."
# Digest::SHA512.hexdigest 'abc' # => "ddaf35a19..."
#
# # Compute digest by chunks
# sha2 = Digest::SHA2.new # =>#<Digest::SHA2:256>
# sha2.update "ab"
# sha2 << "c" # alias for #update

# = PStore -- Transactional File Storage for Ruby Objects
#
# pstore.rb -
# originally by matz

# improved by Hongli Lai
#
# See PStore for documentation.
require "digest"
#
# PStore implements a file based persistence mechanism based on a Hash. User
# code can store hierarchies of Ruby objects (values) into the data store file
# by name (keys). An object hierarchy may be just a single object. User code
# may later read values back from the data store or even update data, as needed.
#
# The transactional behavior ensures that any changes succeed or fail together.
# This can be used to ensure that the data store is not left in a transitory
# state, where some values were updated but others were not.
#
# Behind the scenes, Ruby objects are stored to the data store file with
# Marshal. That carries the usual limitations. Proc objects cannot be
# marshalled, for example.
#
# == Usage example:
#
# require "pstore"
#
# # a mock wiki object...
# class WikiPage
# def initialize( page_name, author, contents )
# @page_name = page_name
# @revisions = Array.new
#
# add_revision(author, contents)
# end
#
# attr_reader :page_name
#
# def add_revision( author, contents )
# @revisions << { :created => Time.now,
# :author => author,
# :contents => contents }
# end
#
# def wiki_page_references
# [@page_name] + @revisions.last[:contents].scan(/\b(?:[A-Z]+[a-z]+){2,}/)
# end
#
# # ...
# end
#
# # create a new page...
# home_page = WikiPage.new( "HomePage", "James Edward Gray II",
# "A page about the JoysOfDocumentation..." )
#
# # then we want to update page data and the index together, or not at all...
# wiki = PStore.new("wiki_pages.pstore")
# wiki.transaction do # begin transaction; do all of this or none of it
# # store page...
# wiki[home_page.page_name] = home_page
# # ensure that an index has been created...
# wiki[:wiki_index] ||= Array.new
# # update wiki index...
# wiki[:wiki_index].push(*home_page.wiki_page_references)
# end # commit changes to wiki data store file
#
# ### Some time later... ###
#
# # read wiki data...
# wiki.transaction(true) do # begin read-only transaction, no changes allowed
# wiki.roots.each do |data_root_name|
# p data_root_name
# p wiki[data_root_name]
# end
# end
#
# == Transaction modes
#
# By default, file integrity is only ensured as long as the operating system
# (and the underlying hardware) doesn't raise any unexpected I/O errors. If an
# I/O error occurs while PStore is writing to its file, then the file will
# become corrupted.
#
# You can prevent this by setting <em>pstore.ultra_safe = true</em>.
# However, this results in a minor performance loss, and only works on platforms
# that support atomic file renames. Please consult the documentation for
# +ultra_safe+ for details.
#
# Needless to say, if you're storing valuable data with PStore, then you should
# backup the PStore files from time to time.

# of SSLConfig, and will setup the certificate for its session for the
# configuration. If want it to generate a generic certificate, the bare
# minimum is to provide the :SSLCertName
#
# === Config options
#
# From +config+ Hash:
#
# :SSLCertificate ::
# An instance of OpenSSL::X509::Certificate. If this is not provided,
# then a generic X509 is generated, with a correspond :SSLPrivateKey
#
# :SSLPrivateKey ::
# A private key instance, like OpenSSL::PKey::RSA. This key must be
# the key that signed the :SSLCertificate
#
# :SSLClientCA ::
# An OpenSSL::X509::Certificate, or Array of certificates that will
# used as ClientCAs in the SSL Context
#
# :SSLCACertificatePath ::
# A path to the directory of CA certificates. The certificates must
# be in PEM format.
#
# :SSLCACertificateFile ::
# A path to a CA certificate file, in PEM format.
#
# :SSLTmpDhCallback ::
# A DH callback. See OpenSSL::SSL::SSLContext.tmp_dh_callback
#
# :SSLVerifyMode ::
# This is the SSL verification mode. See OpenSSL::SSL::VERIFY_* for
# available modes. The default is OpenSSL::SSL::VERIFY_NONE
#
# :SSLVerifyDepth ::
# Number of CA certificates to walk, when verifying a certificate
# chain.
#
# :SSLVerifyCallback ::
# A callback to be used for additional verification. See
# OpenSSL::SSL::SSLContext.verify_callback
#
# :SSLCertificateStore ::
# A OpenSSL::X509::Store used for verification of certificates
#
# :SSLCertName ::
# Issuer name for the certificate. This is required when generating
# the certificate (if :SSLCertificate and :SSLPrivateKey were not
# given). The value of this is to be an Array of pairs:
#
# [["C", "Raleigh"], ["ST","North Carolina"],
# ["CN","fqdn.example.com"]]
#
# See also OpenSSL::X509::Name
#
# :SSLCertComment ::
# A comment to be used for generating the certificate. The default is
# "Generated by Ruby/OpenSSL"
#
#
# === Example
#
# These values can be added after the fact, like a Hash.

# == Overview
#
# dRuby is a distributed object system for Ruby. It allows an object in one
# Ruby process to invoke methods on an object in another Ruby process on the
# same or a different machine.
#
# The Ruby standard library contains the core classes of the dRuby package.
# However, the full package also includes access control lists and the
# Rinda tuple-space distributed task management system, as well as a
# large number of samples. The full dRuby package can be downloaded from
# the dRuby home page (see *References*).
#
# For an introduction and examples of usage see the documentation to the
# DRb module.

#
# == Overview
#
# dRuby is a distributed object system for Ruby. It is written in
# pure Ruby and uses its own protocol. No add-in services are needed
# beyond those provided by the Ruby runtime, such as TCP sockets. It
# does not rely on or interoperate with other distributed object
# systems such as CORBA, RMI, or .NET.
#
# dRuby allows methods to be called in one Ruby process upon a Ruby
# object located in another Ruby process, even on another machine.
# References to objects can be passed between processes. Method
# arguments and return values are dumped and loaded in marshalled
# format. All of this is done transparently to both the caller of the
# remote method and the object that it is called upon.
#
# An object in a remote process is locally represented by a
# DRb::DRbObject instance. This acts as a sort of proxy for the
# remote object. Methods called upon this DRbObject instance are
# forwarded to its remote object. This is arranged dynamically at run
# time. There are no statically declared interfaces for remote
# objects, such as CORBA's IDL.
#
# dRuby calls made into a process are handled by a DRb::DRbServer
# instance within that process. This reconstitutes the method call,
# invokes it upon the specified local object, and returns the value to
# the remote caller. Any object can receive calls over dRuby. There
# is no need to implement a special interface, or mixin special
# functionality. Nor, in the general case, does an object need to
# explicitly register itself with a DRbServer in order to receive
# dRuby calls.
#
# One process wishing to make dRuby calls upon another process must
# somehow obtain an initial reference to an object in the remote
# process by some means other than as the return value of a remote
# method call, as there is initially no remote object reference it can
# invoke a method upon. This is done by attaching to the server by
# URI. Each DRbServer binds itself to a URI such as
# 'druby://example.com:8787'. A DRbServer can have an object attached
# to it that acts as the server's *front* *object*. A DRbObject can
# be explicitly created from the server's URI. This DRbObject's
# remote object will be the server's front object. This front object
# can then return references to other Ruby objects in the DRbServer's
# process.
#
# Method calls made over dRuby behave largely the same as normal Ruby
# method calls made within a process. Method calls with blocks are
# supported, as are raising exceptions. In addition to a method's
# standard errors, a dRuby call may also raise one of the
# dRuby-specific errors, all of which are subclasses of DRb::DRbError.
#
# Any type of object can be passed as an argument to a dRuby call or
# returned as its return value. By default, such objects are dumped
# or marshalled at the local end, then loaded or unmarshalled at the
# remote end. The remote end therefore receives a copy of the local
# object, not a distributed reference to it; methods invoked upon this
# copy are executed entirely in the remote process, not passed on to
# the local original. This has semantics similar to pass-by-value.
#
# However, if an object cannot be marshalled, a dRuby reference to it
# is passed or returned instead. This will turn up at the remote end
# as a DRbObject instance. All methods invoked upon this remote proxy
# are forwarded to the local object, as described in the discussion of
# DRbObjects. This has semantics similar to the normal Ruby
# pass-by-reference.
#
# The easiest way to signal that we want an otherwise marshallable
# object to be passed or returned as a DRbObject reference, rather
# than marshalled and sent as a copy, is to include the
# DRb::DRbUndumped mixin module.
#
# dRuby supports calling remote methods with blocks. As blocks (or
# rather the Proc objects that represent them) are not marshallable,
# the block executes in the local, not the remote, context. Each
# value yielded to the block is passed from the remote object to the
# local block, then the value returned by each block invocation is
# passed back to the remote execution context to be collected, before
# the collected values are finally returned to the local context as
# the return value of the method invocation.
#
# == Examples of usage
#
# For more dRuby samples, see the +samples+ directory in the full
# dRuby distribution.
#
# === dRuby in client/server mode
#
# This illustrates setting up a simple client-server drb
# system. Run the server and client code in different terminals,
# starting the server code first.
#
# ==== Server code
#
# require 'drb/drb'
#
# # The URI for the server to connect to
# URI="druby://localhost:8787"
#
# class TimeServer
#
# def get_current_time
# return Time.now
# end
#
# end
#
# # The object that handles requests on the server
# FRONT_OBJECT=TimeServer.new
#
# DRb.start_service(URI, FRONT_OBJECT)
# # Wait for the drb server thread to finish before exiting.
# DRb.thread.join
#
# ==== Client code
#
# require 'drb/drb'
#
# # The URI to connect to
# SERVER_URI="druby://localhost:8787"
#
# # Start a local DRbServer to handle callbacks.
# #
# # Not necessary for this small example, but will be required
# # as soon as we pass a non-marshallable object as an argument
# # to a dRuby call.
# #
# # Note: this must be called at least once per process to take any effect.
# # This is particularly important if your application forks.
# DRb.start_service
#
# timeserver = DRbObject.new_with_uri(SERVER_URI)
# puts timeserver.get_current_time
#
# === Remote objects under dRuby
#
# This example illustrates returning a reference to an object
# from a dRuby call. The Logger instances live in the server
# process. References to them are returned to the client process,
# where methods can be invoked upon them. These methods are
# executed in the server process.
#
# ==== Server code
#
# require 'drb/drb'
#
# URI="druby://localhost:8787"
#
# class Logger
#
# # Make dRuby send Logger instances as dRuby references,
# # not copies.
# include DRb::DRbUndumped
#
# def initialize(n, fname)
# @name = n
# @filename = fname
# end
#
# def log(message)
# File.open(@filename, "a") do |f|
# f.puts("#{Time.now}: #{@name}: #{message}")
# end
# end
#
# end
#
# # We have a central object for creating and retrieving loggers.
# # This retains a local reference to all loggers created. This
# # is so an existing logger can be looked up by name, but also
# # to prevent loggers from being garbage collected. A dRuby
# # reference to an object is not sufficient to prevent it being
# # garbage collected!
# class LoggerFactory
#
# def initialize(bdir)
# @basedir = bdir
# @loggers = {}
# end
#
# def get_logger(name)
# if !@loggers.has_key? name
# # make the filename safe, then declare it to be so
# fname = name.gsub(/[.\/\\\:]/, "_")
# @loggers[name] = Logger.new(name, @basedir + "/" + fname)
# end
# return @loggers[name]
# end
#
# end
#
# FRONT_OBJECT=LoggerFactory.new("/tmp/dlog")
#
# DRb.start_service(URI, FRONT_OBJECT)
# DRb.thread.join
#
# ==== Client code
#
# require 'drb/drb'
#
# SERVER_URI="druby://localhost:8787"
#
# DRb.start_service
#
# log_service=DRbObject.new_with_uri(SERVER_URI)
#
# ["loga", "logb", "logc"].each do |logname|
#
# logger=log_service.get_logger(logname)
#
# logger.log("Hello, world!")
# logger.log("Goodbye, world!")
# logger.log("=== EOT ===")
#
# end
#
# == Security
#
# As with all network services, security needs to be considered when
# using dRuby. By allowing external access to a Ruby object, you are
# not only allowing outside clients to call the methods you have
# defined for that object, but by default to execute arbitrary Ruby
# code on your server. Consider the following:
#
# # !!! UNSAFE CODE !!!
# ro = DRbObject::new_with_uri("druby://your.server.com:8989")
# class << ro
# undef :instance_eval # force call to be passed to remote object
# end
# ro.instance_eval("`rm -rf *`")
#
# The dangers posed by instance_eval and friends are such that a
# DRbServer should only be used when clients are trusted.
#
# A DRbServer can be configured with an access control list to
# selectively allow or deny access from specified IP addresses. The
# main druby distribution provides the ACL class for this purpose. In
# general, this mechanism should only be used alongside, rather than
# as a replacement for, a good firewall.
#
# == dRuby internals
#
# dRuby is implemented using three main components: a remote method
# call marshaller/unmarshaller; a transport protocol; and an
# ID-to-object mapper. The latter two can be directly, and the first
# indirectly, replaced, in order to provide different behaviour and
# capabilities.
#
# Marshalling and unmarshalling of remote method calls is performed by
# a DRb::DRbMessage instance. This uses the Marshal module to dump
# the method call before sending it over the transport layer, then
# reconstitute it at the other end. There is normally no need to
# replace this component, and no direct way is provided to do so.
# However, it is possible to implement an alternative marshalling
# scheme as part of an implementation of the transport layer.
#
# The transport layer is responsible for opening client and server
# network connections and forwarding dRuby request across them.
# Normally, it uses DRb::DRbMessage internally to manage marshalling
# and unmarshalling. The transport layer is managed by
# DRb::DRbProtocol. Multiple protocols can be installed in
# DRbProtocol at the one time; selection between them is determined by
# the scheme of a dRuby URI. The default transport protocol is
# selected by the scheme 'druby:', and implemented by
# DRb::DRbTCPSocket. This uses plain TCP/IP sockets for
# communication. An alternative protocol, using UNIX domain sockets,
# is implemented by DRb::DRbUNIXSocket in the file drb/unix.rb, and
# selected by the scheme 'drbunix:'. A sample implementation over
# HTTP can be found in the samples accompanying the main dRuby
# distribution.
#
# The ID-to-object mapping component maps dRuby object ids to the
# objects they refer to, and vice versa. The implementation to use
# can be specified as part of a DRb::DRbServer's configuration. The
# default implementation is provided by DRb::DRbIdConv. It uses an
# object's ObjectSpace id as its dRuby id. This means that the dRuby
# reference to that object only remains meaningful for the lifetime of
# the object's process and the lifetime of the object within that
# process. A modified implementation is provided by DRb::TimerIdConv
# in the file drb/timeridconv.rb. This implementation retains a local
# reference to all objects exported over dRuby for a configurable
# period of time (defaulting to ten minutes), to prevent them being
# garbage-collected within this time. Another sample implementation
# is provided in sample/name.rb in the main dRuby distribution. This
# allows objects to specify their own id or "name". A dRuby reference
# can be made persistent across processes by having each process
# register an object using the same dRuby name.
#

# __id__ as its id. This means that an object's identification over
# drb remains valid only while that object instance remains alive
# within the server runtime.
#

# and DRbNameIdConv in sample/name.rb in the full drb distribution.

# Module managing the underlying network protocol(s) used by drb.
#
# By default, drb uses the DRbTCPSocket protocol. Other protocols
# can be defined. A protocol must define the following class methods:
#
# [open(uri, config)] Open a client connection to the server at +uri+,
# using configuration +config+. Return a protocol
# instance for this connection.
# [open_server(uri, config)] Open a server listening at +uri+,
# using configuration +config+. Return a
# protocol instance for this listener.
# [uri_option(uri, config)] Take a URI, possibly containing an option
# component (e.g. a trailing '?param=val'),
# and return a [uri, option] tuple.
#
# All of these methods should raise a DRbBadScheme error if the URI
# does not identify the protocol they support (e.g. "druby:" for
# the standard Ruby protocol). This is how the DRbProtocol module,
# given a URI, determines which protocol implementation serves that
# protocol.
#
# The protocol instance returned by #open_server must have the
# following methods:
#
# [accept] Accept a new connection to the server. Returns a protocol
# instance capable of communicating with the client.
# [close] Close the server connection.
# [uri] Get the URI for this server.
#
# The protocol instance returned by #open must have the following methods:
#
# [send_request (ref, msg_id, arg, b)]
# Send a request to +ref+ with the given message id and arguments.
# This is most easily implemented by calling DRbMessage.send_request,
# providing a stream that sits on top of the current protocol.
# [recv_reply]
# Receive a reply from the server and return it as a [success-boolean,
# reply-value] pair. This is most easily implemented by calling
# DRb.recv_reply, providing a stream that sits on top of the
# current protocol.
# [alive?]
# Is this connection still alive?
# [close]
# Close this connection.
#
# The protocol instance returned by #open_server().accept() must have
# the following methods:
#
# [recv_request]
# Receive a request from the client and return a [object, message,
# args, block] tuple. This is most easily implemented by calling
# DRbMessage.recv_request, providing a stream that sits on top of
# the current protocol.
# [send_reply(succ, result)]
# Send a reply to the client. This is most easily implemented
# by calling DRbMessage.send_reply, providing a stream that sits
# on top of the current protocol.
# [close]
# Close this connection.
#
# A new protocol is registered with the DRbProtocol module using
# the add_protocol method.
#
# For examples of other protocols, see DRbUNIXSocket in drb/unix.rb,
# and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full

#
# Open3.popen3([env,] cmd... [, opts]) {|stdin, stdout, stderr, wait_thr|

# pid = wait_thr[:pid] # pid of the started process
# ...
# stdin.close # stdin, stdout and stderr should be closed explicitly in this form.
# stdout.close
# stderr.close
# exit_status = wait_thr.value # Process::Status object returned.
#
# The parameters env, cmd, and opts are passed to Process.spawn.
# A commandline string and a list of argument strings can be accepted as follows:
#
# Open3.popen3("echo abc") {|i, o, e, t| ... }
# Open3.popen3("echo", "abc") {|i, o, e, t| ... }
# Open3.popen3(["echo", "argv0"], "abc") {|i, o, e, t| ... }
#
# If the last parameter, opts, is a Hash, it is recognized as an option for Process.spawn.
#
# Open3.popen3("pwd", :chdir=>"/") {|i,o,e,t|
# p o.read.chomp #=> "/"
# }
#
# wait_thr.value waits for the termination of the process.
# The block form also waits for the process when it returns.
#
# Closing stdin, stdout and stderr does not wait for the process to complete.
#
# You should be careful to avoid deadlocks.
# Since pipes are fixed length buffers,
# Open3.popen3("prog") {|i, o, e, t| o.read } deadlocks if
# the program generates too much output on stderr.
# You should read stdout and stderr simultaneously (using threads or IO.select).

# == OptionParser
#
# === Introduction
#
# OptionParser is a class for command-line option analysis. It is much more
# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
# solution.
#
# === Features
#
# 1. The argument specification and the code to handle it are written in the
# same place.
# 2. It can output an option summary; you don't need to maintain this string
# separately.
# 3. Optional and mandatory arguments are specified very gracefully.
# 4. Arguments can be automatically converted to a specified class.
# 5. Arguments can be restricted to a certain set.
#
# All of these features are demonstrated in the examples below. See
# #make_switch for full documentation.
#
# === Minimal example
#
# require 'optparse'
#
# options = {}
# OptionParser.new do |parser|
# parser.banner = "Usage: example.rb [options]"
#
# parser.on("-v", "--[no-]verbose", "Run verbosely") do |v|
# options[:verbose] = v
# end
# end.parse!
#
# p options
# p ARGV
#
# === Generating Help
#
# OptionParser can be used to automatically generate help for the commands you
# write:
#
# require 'optparse'
#
# Options = Struct.new(:name)
#
# class Parser
# def self.parse(options)
# args = Options.new("world")
#
# opt_parser = OptionParser.new do |parser|
# parser.banner = "Usage: example.rb [options]"
#
# parser.on("-nNAME", "--name=NAME", "Name to say hello to") do |n|
# args.name = n
# end
#
# parser.on("-h", "--help", "Prints this help") do
# puts parser
# exit
# end
# end
#
# opt_parser.parse!(options)
# return args
# end
# end
# options = Parser.parse %w[--help]
#
# #=>
# # Usage: example.rb [options]
# # -n, --name=NAME Name to say hello to
# # -h, --help Prints this help
#
# === Required Arguments
#
# For options that require an argument, option specification strings may include an
# option name in all caps. If an option is used without the required argument,
# an exception will be raised.
#
# require 'optparse'
#
# options = {}
# OptionParser.new do |parser|
# parser.on("-r", "--require LIBRARY",
# "Require the LIBRARY before executing your script") do |lib|
# puts "You required #{lib}!"
# end
# end.parse!
#
# Used:
#
# $ ruby optparse-test.rb -r
# optparse-test.rb:9:in `<main>': missing argument: -r (OptionParser::MissingArgument)
# $ ruby optparse-test.rb -r my-library
# You required my-library!
#
# === Type Coercion
#
# OptionParser supports the ability to coerce command line arguments
# into objects for us.
#
# OptionParser comes with a few ready-to-use kinds of type
# coercion. They are:
#
# - Date -- Anything accepted by +Date.parse+
# - DateTime -- Anything accepted by +DateTime.parse+
# - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+
# - URI -- Anything accepted by +URI.parse+
# - Shellwords -- Anything accepted by +Shellwords.shellwords+
# - String -- Any non-empty string
# - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040)
# - Float -- Any float. (e.g. 10, 3.14, -100E+13)
# - Numeric -- Any integer, float, or rational (1, 3.4, 1/3)
# - DecimalInteger -- Like +Integer+, but no octal format.
# - OctalInteger -- Like +Integer+, but no decimal format.
# - DecimalNumeric -- Decimal integer or float.
# - TrueClass -- Accepts '+, yes, true, -, no, false' and
# defaults as +true+
# - FalseClass -- Same as +TrueClass+, but defaults to +false+
# - Array -- Strings separated by ',' (e.g. 1,2,3)
# - Regexp -- Regular expressions. Also includes options.
#
# We can also add our own coercions, which we will cover below.
#
# ==== Using Built-in Conversions
#
# As an example, the built-in +Time+ conversion is used. The other built-in
# conversions behave in the same way.
# OptionParser will attempt to parse the argument
# as a +Time+. If it succeeds, that time will be passed to the
# handler block. Otherwise, an exception will be raised.
#
# require 'optparse'
# require 'optparse/time'
# OptionParser.new do |parser|
# parser.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
# p time
# end
# end.parse!
#
# Used:
#
# $ ruby optparse-test.rb -t nonsense
# ... invalid argument: -t nonsense (OptionParser::InvalidArgument)
# $ ruby optparse-test.rb -t 10-11-12
# 2010-11-12 00:00:00 -0500
# $ ruby optparse-test.rb -t 9:30
# 2014-08-13 09:30:00 -0400
#
# ==== Creating Custom Conversions
#
# The +accept+ method on OptionParser may be used to create converters.
# It specifies which conversion block to call whenever a class is specified.
# The example below uses it to fetch a +User+ object before the +on+ handler receives it.
#
# require 'optparse'
#
# User = Struct.new(:id, :name)
#
# def find_user id
# not_found = ->{ raise "No User Found for id #{id}" }
# [ User.new(1, "Sam"),
# User.new(2, "Gandalf") ].find(not_found) do |u|
# u.id == id
# end
# end
#
# op = OptionParser.new
# op.accept(User) do |user_id|
# find_user user_id.to_i
# end
#
# op.on("--user ID", User) do |user|
# puts user
# end
#
# op.parse!
#
# Used:
#
# $ ruby optparse-test.rb --user 1
# #<struct User id=1, name="Sam">
# $ ruby optparse-test.rb --user 2
# #<struct User id=2, name="Gandalf">
# $ ruby optparse-test.rb --user 3
# optparse-test.rb:15:in `block in find_user': No User Found for id 3 (RuntimeError)
#
# === Store options to a Hash
#
# The +into+ option of +order+, +parse+ and so on methods stores command line options into a Hash.
#
# require 'optparse'
#
# params = {}
# OptionParser.new do |parser|
# parser.on('-a')
# parser.on('-b NUM', Integer)
# parser.on('-v', '--verbose')
# end.parse!(into: params)
#
# p params
#
# Used:
#
# $ ruby optparse-test.rb -a
# {:a=>true}
# $ ruby optparse-test.rb -a -v
# {:a=>true, :verbose=>true}
# $ ruby optparse-test.rb -a -b 100
# {:a=>true, :b=>100}
#
# === Complete example
#
# The following example is a complete Ruby program. You can run it and see the
# effect of specifying various options. This is probably the best way to learn
# the features of +optparse+.

# One of the following:
# :NONE, :REQUIRED, :OPTIONAL
#
# [Argument pattern:]
# Acceptable option argument format, must be pre-defined with
# OptionParser.accept or OptionParser#accept, or Regexp. This can appear
# once or assigned as String if not present, otherwise causes an
# ArgumentError. Examples:
# Float, Time, Array
#
# [Possible argument values:]
# Hash or Array.
# [:text, :binary, :auto]
# %w[iso-2022-jp shift_jis euc-jp utf8 binary]
# { "jis" => "iso-2022-jp", "sjis" => "shift_jis" }
#
# [Long style switch:]
# Specifies a long style switch which takes a mandatory, optional or no
# argument. It's a string of the following form:
# "--switch=MANDATORY" or "--switch MANDATORY"
# "--switch[=OPTIONAL]"
# "--switch"
#
# [Short style switch:]
# Specifies short style switch which takes a mandatory, optional or no
# argument. It's a string of the following form:
# "-xMANDATORY"
# "-x[OPTIONAL]"
# "-x"
# There is also a special form which matches character range (not full
# set of regular expression):
# "-[a-z]MANDATORY"
# "-[a-z][OPTIONAL]"
# "-[a-z]"
#
# [Argument style and description:]
# Instead of specifying mandatory or optional arguments directly in the
# switch parameter, this separate parameter can be used.
# "=MANDATORY"
# "=[OPTIONAL]"
#
# [Description:]
# Description string for the option.
# "Run verbosely"
# If you give multiple description strings, each string will be printed
# line by line.
#
# [Handler:]
# Handler for the parsed argument value. Either give a block or pass a
# Proc or Method as an argument.
#

##
# == Manipulates strings like the UNIX Bourne shell
#
# This module manipulates strings according to the word parsing rules
# of the UNIX Bourne shell.
#
# The shellwords() function was originally a port of shellwords.pl,
# but modified to conform to the Shell & Utilities volume of the IEEE
# Std 1003.1-2008, 2016 Edition [1].
#
# === Usage
#
# You can use Shellwords to parse a string into a Bourne shell friendly Array.
#
# require 'shellwords'
#
# argv = Shellwords.split('three blind "mice"')
# argv #=> ["three", "blind", "mice"]
#
# Once you've required Shellwords, you can use the #split alias
# String#shellsplit.
#
# argv = "see how they run".shellsplit
# argv #=> ["see", "how", "they", "run"]
#
# They treat quotes as special characters, so an unmatched quote will
# cause an ArgumentError.
#
# argv = "they all ran after the farmer's wife".shellsplit
# #=> ArgumentError: Unmatched quote: ...
#
# Shellwords also provides methods that do the opposite.
# Shellwords.escape, or its alias, String#shellescape, escapes
# shell metacharacters in a string for use in a command line.
#
# filename = "special's.txt"
#
# system("cat -- #{filename.shellescape}")
# # runs "cat -- special\\'s.txt"
#
# Note the '--'. Without it, cat(1) will treat the following argument
# as a command line option if it starts with '-'. It is guaranteed
# that Shellwords.escape converts a string to a form that a Bourne
# shell will parse back to the original string, but it is the
# programmer's responsibility to make sure that passing an arbitrary
# argument to a command does no harm.
#
# Shellwords also comes with a core extension for Array, Array#shelljoin.
#
# dir = "Funny GIFs"
# argv = %W[ls -lta -- #{dir}]
# system(argv.shelljoin + " | less")
# # runs "ls -lta -- Funny\\ GIFs | less"
#
# You can use this method to build a complete command line out of an
# array of arguments.

#
# forwardable.rb -
# $Release Version: 1.1$
# $Revision$
# by Keiju ISHITSUKA(keiju@ishitsuka.com)
# original definition by delegator.rb
# Revised by Daniel J. Berger with suggestions from Florian Gross.
#
# Documentation by James Edward Gray II and Gavin Sinclair
# The Forwardable module provides delegation of specified
# methods to a designated object, using the methods #def_delegator
# and #def_delegators.
#
# For example, say you have a class RecordCollection which
# contains an array <tt>@records</tt>. You could provide the lookup method
# #record_number(), which simply calls #[] on the <tt>@records</tt>
# array, like this:
#
# require 'forwardable'
#
# class RecordCollection
# attr_accessor :records
# extend Forwardable
# def_delegator :@records, :[], :record_number
# end
#
# We can use the lookup method like so:
#
# r = RecordCollection.new
# r.records = [4,5,6]
# r.record_number(0) # => 4
#
# Further, if you wish to provide the methods #size, #<<, and #map,
# all of which delegate to @records, this is how you can do it:
#
# class RecordCollection # re-open RecordCollection class
# def_delegators :@records, :size, :<<, :map
# end
#
# r = RecordCollection.new
# r.records = [1,2,3]
# r.record_number(0) # => 1
# r.size # => 3
# r << 4 # => [1, 2, 3, 4]
# r.map { |x| x * 2 } # => [2, 4, 6, 8]
#
# You can even extend regular objects with Forwardable.
#
# my_hash = Hash.new
# my_hash.extend Forwardable # prepare object for delegation
# my_hash.def_delegator "STDOUT", "puts" # add delegation for STDOUT.puts()
# my_hash.puts "Howdy!"
#
# == Another example
#
# You could use Forwardable as an alternative to inheritance, when you don't want
# to inherit all methods from the superclass. For instance, here is how you might
# add a range of +Array+ instance methods to a new class +Queue+:
#
# class Queue
# extend Forwardable
#
# def initialize
# @q = [ ] # prepare delegate object
# end
#
# # setup preferred interface, enq() and deq()...
# def_delegator :@q, :push, :enq
# def_delegator :@q, :shift, :deq
#
# # support some general Array methods that fit Queues well
# def_delegators :@q, :clear, :first, :push, :shift, :size
# end
#
# q = Queue.new
# q.enq 1, 2, 3, 4, 5
# q.push 6
#
# q.shift # => 1
# while q.size > 0
# puts q.deq
# end
#
# q.enq "Ruby", "Perl", "Python"
# puts q.first
# q.clear
# puts q.first
#
# This should output:
#
# 2
# 3
# 4
# 5
# 6
# Ruby
# nil
#
# == Notes
#
# Be advised, RDoc will not detect delegated methods.
#
# +forwardable.rb+ provides single-method delegation via the def_delegator and
# def_delegators methods. For full-class delegation via DelegateClass, see
# +delegate.rb+.

# The Singleton module implements the Singleton pattern.
#
# == Usage
#
# To use Singleton, include the module in your class.
#
# class Klass
# include Singleton
# # ...
# end
#
# This ensures that only one instance of Klass can be created.
#
# a,b = Klass.instance, Klass.instance
#
# a == b
# # => true
#
# Klass.new
# # => NoMethodError - new is private ...
#
# The instance is created at upon the first call of Klass.instance().
#
# class OtherKlass
# include Singleton
# # ...
# end
#
# ObjectSpace.each_object(OtherKlass){}
# # => 0
#
# OtherKlass.instance
# ObjectSpace.each_object(OtherKlass){}
# # => 1
#
#
# This behavior is preserved under inheritance and cloning.
#
# == Implementation
#
# This above is achieved by:
#
# * Making Klass.new and Klass.allocate private.
#
# * Overriding Klass.inherited(sub_klass) and Klass.clone() to ensure that the
# Singleton properties are kept when inherited and cloned.
#
# * Providing the Klass.instance() method that returns the same object each
# time it is called.
#
# * Overriding Klass._load(str) to call Klass.instance().
#
# * Overriding Klass#clone and Klass#dup to raise TypeErrors to prevent
# cloning or duping.
#
# == Singleton and Marshal
#
# By default Singleton's #_dump(depth) returns the empty string. Marshalling by
# default will strip state information, e.g. instance variables from the instance.
# Classes using Singleton can provide custom _load(str) and _dump(depth) methods
# to retain some of the previous state of the instance.
#
# require 'singleton'
#
# class Example
# include Singleton
# attr_accessor :keep, :strip
# def _dump(depth)
# # this strips the @strip information from the instance
# Marshal.dump(@keep, depth)
# end
#
# def self._load(str)
# instance.keep = Marshal.load(str)
# instance
# end
# end
#
# a = Example.instance
# a.keep = "keep this"
# a.strip = "get rid of this"
#
# stored_state = Marshal.dump(a)
#
# a.keep = nil
# a.strip = nil
# b = Marshal.load(stored_state)
# p a == b # => true
# p a.keep # => "keep this"
# p a.strip # => nil
#

# = Overview
#
# Psych is a YAML parser and emitter.
# Psych leverages libyaml [Home page: https://pyyaml.org/wiki/LibYAML]
# or [HG repo: https://bitbucket.org/xi/libyaml] for its YAML parsing
# and emitting capabilities. In addition to wrapping libyaml, Psych also
# knows how to serialize and de-serialize most Ruby objects to and from
# the YAML format.
#
# = I NEED TO PARSE OR EMIT YAML RIGHT NOW!
#
# # Parse some YAML
# Psych.load("--- foo") # => "foo"
#
# # Emit some YAML
# Psych.dump("foo") # => "--- foo\n...\n"
# { :a => 'b'}.to_yaml # => "---\n:a: b\n"
#
# Got more time on your hands? Keep on reading!
#
# == YAML Parsing
#
# Psych provides a range of interfaces for parsing a YAML document ranging from
# low level to high level, depending on your parsing needs. At the lowest
# level, is an event based parser. Mid level is access to the raw YAML AST,
# and at the highest level is the ability to unmarshal YAML to Ruby objects.
#
# == YAML Emitting
#
# Psych provides a range of interfaces ranging from low to high level for
# producing YAML documents. Very similar to the YAML parsing interfaces, Psych
# provides at the lowest level, an event based system, mid-level is building
# a YAML AST, and the highest level is converting a Ruby object straight to
# a YAML document.
#
# == High-level API
#
# === Parsing
#
# The high level YAML parser provided by Psych simply takes YAML as input and
# returns a Ruby data structure. For information on using the high level parser
# see Psych.load
#
# ==== Reading from a string
#
# Psych.safe_load("--- a") # => 'a'
# Psych.safe_load("---\n - a\n - b") # => ['a', 'b']
# # From a trusted string:
# Psych.load("--- !ruby/range\nbegin: 0\nend: 42\nexcl: false\n") # => 0..42
#
# ==== Reading from a file
#
# Psych.safe_load_file("data.yml", permitted_classes: [Date])
# Psych.load_file("trusted_database.yml")
#
# ==== Exception handling
#
# begin
# # The second argument changes only the exception contents
# Psych.parse("--- `", "file.txt")
# rescue Psych::SyntaxError => ex
# ex.file # => 'file.txt'
# ex.message # => "(file.txt): found character that cannot start any token"
# end
#
# === Emitting
#
# The high level emitter has the easiest interface. Psych simply takes a Ruby
# data structure and converts it to a YAML document. See Psych.dump for more
# information on dumping a Ruby data structure.
#
# ==== Writing to a string
#
# # Dump an array, get back a YAML string
# Psych.dump(['a', 'b']) # => "---\n- a\n- b\n"
#
# # Dump an array to an IO object
# Psych.dump(['a', 'b'], StringIO.new) # => #<StringIO:0x000001009d0890>
#
# # Dump an array with indentation set
# Psych.dump(['a', ['b']], :indentation => 3) # => "---\n- a\n- - b\n"
#
# # Dump an array to an IO with indentation set
# Psych.dump(['a', ['b']], StringIO.new, :indentation => 3)
#
# ==== Writing to a file
#
# Currently there is no direct API for dumping Ruby structure to file:
#
# File.open('database.yml', 'w') do |file|
# file.write(Psych.dump(['a', 'b']))
# end
#
# == Mid-level API
#
# === Parsing
#
# Psych provides access to an AST produced from parsing a YAML document. This
# tree is built using the Psych::Parser and Psych::TreeBuilder. The AST can
# be examined and manipulated freely. Please see Psych::parse_stream,
# Psych::Nodes, and Psych::Nodes::Node for more information on dealing with
# YAML syntax trees.
#
# ==== Reading from a string
#
# # Returns Psych::Nodes::Stream
# Psych.parse_stream("---\n - a\n - b")
#
# # Returns Psych::Nodes::Document
# Psych.parse("---\n - a\n - b")
#
# ==== Reading from a file
#
# # Returns Psych::Nodes::Stream
# Psych.parse_stream(File.read('database.yml'))
#
# # Returns Psych::Nodes::Document
# Psych.parse_file('database.yml')
#
# ==== Exception handling
#
# begin
# # The second argument changes only the exception contents
# Psych.parse("--- `", "file.txt")
# rescue Psych::SyntaxError => ex
# ex.file # => 'file.txt'
# ex.message # => "(file.txt): found character that cannot start any token"
# end
#
# === Emitting
#
# At the mid level is building an AST. This AST is exactly the same as the AST
# used when parsing a YAML document. Users can build an AST by hand and the
# AST knows how to emit itself as a YAML document. See Psych::Nodes,
# Psych::Nodes::Node, and Psych::TreeBuilder for more information on building
# a YAML AST.
#
# ==== Writing to a string
#
# # We need Psych::Nodes::Stream (not Psych::Nodes::Document)
# stream = Psych.parse_stream("---\n - a\n - b")
#
# stream.to_yaml # => "---\n- a\n- b\n"
#
# ==== Writing to a file
#
# # We need Psych::Nodes::Stream (not Psych::Nodes::Document)
# stream = Psych.parse_stream(File.read('database.yml'))
#
# File.open('database.yml', 'w') do |file|
# file.write(stream.to_yaml)
# end
#
# == Low-level API
#
# === Parsing
#
# The lowest level parser should be used when the YAML input is already known,
# and the developer does not want to pay the price of building an AST or
# automatic detection and conversion to Ruby objects. See Psych::Parser for
# more information on using the event based parser.
#
# ==== Reading to Psych::Nodes::Stream structure
#
# parser = Psych::Parser.new(TreeBuilder.new) # => #<Psych::Parser>
# parser = Psych.parser # it's an alias for the above
#
# parser.parse("---\n - a\n - b") # => #<Psych::Parser>
# parser.handler # => #<Psych::TreeBuilder>
# parser.handler.root # => #<Psych::Nodes::Stream>
#
# ==== Receiving an events stream
#
# recorder = Psych::Handlers::Recorder.new
# parser = Psych::Parser.new(recorder)
#
# parser.parse("---\n - a\n - b")
# recorder.events # => [list of [event, args] lists]
# # event is one of: Psych::Handler::EVENTS
# # args are the arguments passed to the event
#
# === Emitting
#
# The lowest level emitter is an event based system. Events are sent to a
# Psych::Emitter object. That object knows how to convert the events to a YAML
# document. This interface should be used when document format is known in
# advance or speed is a concern. See Psych::Emitter for more information.
#
# ==== Writing to a Ruby structure
#
# Psych.parser.parse("--- a") # => #<Psych::Parser>
#
# parser.handler.first # => #<Psych::Nodes::Stream>
# parser.handler.first.to_ruby # => ["a"]
#
# parser.handler.root.first # => #<Psych::Nodes::Document>
# parser.handler.root.first.to_ruby # => "a"
#
# # You can instantiate an Emitter manually
# Psych::Visitors::ToRuby.new.accept(parser.handler.root.first)
# # => "a"

# URI is a module providing classes to handle Uniform Resource Identifiers
# (RFC2396[http://tools.ietf.org/html/rfc2396]).
#
# == Features
#
# * Uniform way of handling URIs.
# * Flexibility to introduce custom URI schemes.
# * Flexibility to have an alternate URI::Parser (or just different patterns
# and regexp's).
#
# == Basic example
#
# require 'uri'
#
# uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
# #=> #<URI::HTTP http://foo.com/posts?id=30&limit=5#time=1305298413>
#
# uri.scheme #=> "http"
# uri.host #=> "foo.com"
# uri.path #=> "/posts"
# uri.query #=> "id=30&limit=5"
# uri.fragment #=> "time=1305298413"
#
# uri.to_s #=> "http://foo.com/posts?id=30&limit=5#time=1305298413"
#
# == Adding custom URIs
#
# module URI
# class RSYNC < Generic
# DEFAULT_PORT = 873
# end
# @@schemes['RSYNC'] = RSYNC
# end
# #=> URI::RSYNC
#
# URI.scheme_list
# #=> {"FILE"=>URI::File, "FTP"=>URI::FTP, "HTTP"=>URI::HTTP,
# # "HTTPS"=>URI::HTTPS, "LDAP"=>URI::LDAP, "LDAPS"=>URI::LDAPS,
# # "MAILTO"=>URI::MailTo, "RSYNC"=>URI::RSYNC}
#
# uri = URI("rsync://rsync.foo.com")
# #=> #<URI::RSYNC rsync://rsync.foo.com>

# = csv.rb -- CSV Reading and Writing
#
# Created by James Edward Gray II on 2005-10-31.
#
# See CSV for documentation.
#
# == Description
#
# Welcome to the new and improved CSV.
#
# This version of the CSV library began its life as FasterCSV. FasterCSV was
# intended as a replacement to Ruby's then standard CSV library. It was
# designed to address concerns users of that library had and it had three
# primary goals:
#
# 1. Be significantly faster than CSV while remaining a pure Ruby library.
# 2. Use a smaller and easier to maintain code base. (FasterCSV eventually
# grew larger, was also but considerably richer in features. The parsing
# core remains quite small.)
# 3. Improve on the CSV interface.
#
# Obviously, the last one is subjective. I did try to defer to the original
# interface whenever I didn't have a compelling reason to change it though, so
# hopefully this won't be too radically different.
#
# We must have met our goals because FasterCSV was renamed to CSV and replaced
# the original library as of Ruby 1.9. If you are migrating code from 1.8 or
# earlier, you may have to change your code to comply with the new interface.
#
# == What's the Different From the Old CSV?
#
# I'm sure I'll miss something, but I'll try to mention most of the major
# differences I am aware of, to help others quickly get up to speed:
#
# === \CSV Parsing
#
# * This parser is m17n aware. See CSV for full details.
# * This library has a stricter parser and will throw MalformedCSVErrors on
# problematic data.
# * This library has a less liberal idea of a line ending than CSV. What you
# set as the <tt>:row_sep</tt> is law. It can auto-detect your line endings
# though.
# * The old library returned empty lines as <tt>[nil]</tt>. This library calls
# them <tt>[]</tt>.
# * This library has a much faster parser.
#
# === Interface
#
# * CSV now uses Hash-style parameters to set options.
# * CSV no longer has generate_row() or parse_row().
# * The old CSV's Reader and Writer classes have been dropped.
# * CSV::open() is now more like Ruby's open().
# * CSV objects now support most standard IO methods.
# * CSV now has a new() method used to wrap objects like String and IO for
# reading and writing.
# * CSV::generate() is different from the old method.
# * CSV no longer supports partial reads. It works line-by-line.
# * CSV no longer allows the instance methods to override the separators for
# performance reasons. They must be set in the constructor.
#
# If you use this library and find yourself missing any functionality I have
# trimmed, please {let me know}[mailto:james@grayproductions.net].
#
# == Documentation
#
# See CSV for documentation.
#
# == What is CSV, really?
#
# CSV maintains a pretty strict definition of CSV taken directly from
# {the RFC}[http://www.ietf.org/rfc/rfc4180.txt]. I relax the rules in only one
# place and that is to make using this library easier. CSV will parse all valid
# CSV.
#
# What you don't want to do is to feed CSV invalid data. Because of the way the
# CSV format works, it's common for a parser to need to read until the end of
# the file to be sure a field is invalid. This consumes a lot of time and memory.
#
# Luckily, when working with invalid CSV, Ruby's built-in methods will almost
# always be superior in every way. For example, parsing non-quoted fields is as
# easy as:
#
# data.split(",")
#
# == Questions and/or Comments

# Feel free to email {James Edward Gray II}[mailto:james@grayproductions.net]

# == \CSV
# \CSV (comma-separated variables) data is a text representation of a table:
# - A _row_ _separator_ delimits table rows.
# A common row separator is the newline character <tt>"\n"</tt>.
# - A _column_ _separator_ delimits fields in a row.
# A common column separator is the comma character <tt>","</tt>.
#
# This \CSV \String, with row separator <tt>"\n"</tt>
# and column separator <tt>","</tt>,
# has three rows and two columns:
# "foo,0\nbar,1\nbaz,2\n"
#
# Despite the name \CSV, a \CSV representation can use different separators.
#
# For more about tables, see the Wikipedia article
# "{Table (information)}[https://en.wikipedia.org/wiki/Table_(information)]",
# especially its section
# "{Simple table}[https://en.wikipedia.org/wiki/Table_(information)#Simple_table]"

# == \Class \CSV
#
# Class \CSV provides methods for:
# - Parsing \CSV data from a \String object, a \File (via its file path), or an \IO object.
# - Generating \CSV data to a \String object.
#
# To make \CSV available:
# require 'csv'
#
# All examples here assume that this has been done.
#
# == Keeping It Simple
#
# A \CSV object has dozens of instance methods that offer fine-grained control
# of parsing and generating \CSV data.
# For many needs, though, simpler approaches will do.
#
# This section summarizes the singleton methods in \CSV
# that allow you to parse and generate without explicitly
# creating \CSV objects.
# For details, follow the links.
#
# === Simple Parsing
#
# Parsing methods commonly return either of:
# - An \Array of Arrays of Strings:
# - The outer \Array is the entire "table".
# - Each inner \Array is a row.
# - Each \String is a field.
# - A CSV::Table object. For details, see
# {\CSV with Headers}[#class-CSV-label-CSV+with+Headers].
#
# ==== Parsing a \String
#
# The input to be parsed can be a string:
# string = "foo,0\nbar,1\nbaz,2\n"
#
# \Method CSV.parse returns the entire \CSV data:
# CSV.parse(string) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# \Method CSV.parse_line returns only the first row:
# CSV.parse_line(string) # => ["foo", "0"]
#
# \CSV extends class \String with instance method String#parse_csv,
# which also returns only the first row:
# string.parse_csv # => ["foo", "0"]
#
# ==== Parsing Via a \File Path
#
# The input to be parsed can be in a file:
# string = "foo,0\nbar,1\nbaz,2\n"
# path = 't.csv'
# File.write(path, string)
#
# \Method CSV.read returns the entire \CSV data:
# CSV.read(path) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# \Method CSV.foreach iterates, passing each row to the given block:
# CSV.foreach(path) do |row|
# p row
# end
# Output:
# ["foo", "0"]
# ["bar", "1"]
# ["baz", "2"]
#
# \Method CSV.table returns the entire \CSV data as a CSV::Table object:
# CSV.table(path) # => #<CSV::Table mode:col_or_row row_count:3>
#
# ==== Parsing from an Open \IO Stream
#
# The input to be parsed can be in an open \IO stream:
#
# \Method CSV.read returns the entire \CSV data:
# File.open(path) do |file|
# CSV.read(file)
# end # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# As does method CSV.parse:
# File.open(path) do |file|
# CSV.parse(file)
# end # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# \Method CSV.parse_line returns only the first row:
# File.open(path) do |file|
# CSV.parse_line(file)
# end # => ["foo", "0"]
#
# \Method CSV.foreach iterates, passing each row to the given block:
# File.open(path) do |file|
# CSV.foreach(file) do |row|
# p row
# end
# end
# Output:
# ["foo", "0"]
# ["bar", "1"]
# ["baz", "2"]
#
# \Method CSV.table returns the entire \CSV data as a CSV::Table object:
# File.open(path) do |file|
# CSV.table(file)
# end # => #<CSV::Table mode:col_or_row row_count:3>
#
# === Simple Generating
#
# \Method CSV.generate returns a \String;
# this example uses method CSV#<< to append the rows
# that are to be generated:
# output_string = CSV.generate do |csv|
# csv << ['foo', 0]
# csv << ['bar', 1]
# csv << ['baz', 2]
# end
# output_string # => "foo,0\nbar,1\nbaz,2\n"
#
# \Method CSV.generate_line returns a \String containing the single row
# constructed from an \Array:
# CSV.generate_line(['foo', '0']) # => "foo,0\n"
#
# \CSV extends class \Array with instance method <tt>Array#to_csv</tt>,
# which forms an \Array into a \String:
# ['foo', '0'].to_csv # => "foo,0\n"
#
# === "Filtering" \CSV
#
# \Method CSV.filter provides a Unix-style filter for \CSV data.
# The input data is processed to form the output data:
# in_string = "foo,0\nbar,1\nbaz,2\n"
# out_string = ''
# CSV.filter(in_string, out_string) do |row|
# row[0] = row[0].upcase
# row[1] *= 4
# end
# out_string # => "FOO,0000\nBAR,1111\nBAZ,2222\n"
#
# == \CSV Objects
#
# There are three ways to create a \CSV object:
# - \Method CSV.new returns a new \CSV object.
# - \Method CSV.instance returns a new or cached \CSV object.
# - \Method \CSV() also returns a new or cached \CSV object.
#
# === Instance Methods
#
# \CSV has three groups of instance methods:
# - Its own internally defined instance methods.
# - Methods included by module Enumerable.
# - Methods delegated to class IO. See below.
#
# ==== Delegated Methods
#
# For convenience, a CSV object will delegate to many methods in class IO.
# (A few have wrapper "guard code" in \CSV.) You may call:
# * IO#binmode
# * #binmode?
# * IO#close
# * IO#close_read
# * IO#close_write
# * IO#closed?
# * #eof
# * #eof?
# * IO#external_encoding
# * IO#fcntl
# * IO#fileno
# * #flock
# * IO#flush
# * IO#fsync
# * IO#internal_encoding
# * #ioctl
# * IO#isatty
# * #path
# * IO#pid
# * IO#pos
# * IO#pos=
# * IO#reopen
# * #rewind
# * IO#seek
# * #stat
# * IO#string
# * IO#sync
# * IO#sync=
# * IO#tell
# * #to_i
# * #to_io
# * IO#truncate
# * IO#tty?
#
# === Options
#
# The default values for options are:
# DEFAULT_OPTIONS = {
# # For both parsing and generating.
# col_sep: ",",
# row_sep: :auto,
# quote_char: '"',
# # For parsing.
# field_size_limit: nil,

#
# === \CSV with Headers
#
# CSV allows to specify column names of CSV file, whether they are in data, or
# provided separately. If headers are specified, reading methods return an instance
# of CSV::Table, consisting of CSV::Row.
#
# # Headers are part of data
# data = CSV.parse(<<~ROWS, headers: true)
# Name,Department,Salary
# Bob,Engineering,1000
# Jane,Sales,2000
# John,Management,5000
# ROWS
#
# data.class #=> CSV::Table
# data.first #=> #<CSV::Row "Name":"Bob" "Department":"Engineering" "Salary":"1000">
# data.first.to_h #=> {"Name"=>"Bob", "Department"=>"Engineering", "Salary"=>"1000"}
#
# # Headers provided by developer
# data = CSV.parse('Bob,Engineering,1000', headers: %i[name department salary])
# data.first #=> #<CSV::Row name:"Bob" department:"Engineering" salary:"1000">
#
# === \Converters
#
# By default, each value (field or header) parsed by \CSV is formed into a \String.
# You can use a _field_ _converter_ or _header_ _converter_
# to intercept and modify the parsed values:
# - See {Field Converters}[#class-CSV-label-Field+Converters].
# - See {Header Converters}[#class-CSV-label-Header+Converters].
#
# Also by default, each value to be written during generation is written 'as-is'.
# You can use a _write_ _converter_ to modify values before writing.
# - See {Write Converters}[#class-CSV-label-Write+Converters].
#
# ==== Specifying \Converters
#
# You can specify converters for parsing or generating in the +options+
# argument to various \CSV methods:
# - Option +converters+ for converting parsed field values.
# - Option +header_converters+ for converting parsed header values.
# - Option +write_converters+ for converting values to be written (generated).
#
# There are three forms for specifying converters:
# - A converter proc: executable code to be used for conversion.
# - A converter name: the name of a stored converter.
# - A converter list: an array of converter procs, converter names, and converter lists.
#
# ===== Converter Procs
#
# This converter proc, +strip_converter+, accepts a value +field+
# and returns <tt>field.strip</tt>:
# strip_converter = proc {|field| field.strip }
# In this call to <tt>CSV.parse</tt>,
# the keyword argument <tt>converters: string_converter</tt>
# specifies that:
# - \Proc +string_converter+ is to be called for each parsed field.
# - The converter's return value is to replace the +field+ value.
# Example:
# string = " foo , 0 \n bar , 1 \n baz , 2 \n"
# array = CSV.parse(string, converters: strip_converter)
# array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# A converter proc can receive a second argument, +field_info+,
# that contains details about the field.
# This modified +strip_converter+ displays its arguments:
# strip_converter = proc do |field, field_info|
# p [field, field_info]
# field.strip
# end
# string = " foo , 0 \n bar , 1 \n baz , 2 \n"
# array = CSV.parse(string, converters: strip_converter)
# array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
# Output:
# [" foo ", #<struct CSV::FieldInfo index=0, line=1, header=nil>]
# [" 0 ", #<struct CSV::FieldInfo index=1, line=1, header=nil>]
# [" bar ", #<struct CSV::FieldInfo index=0, line=2, header=nil>]
# [" 1 ", #<struct CSV::FieldInfo index=1, line=2, header=nil>]
# [" baz ", #<struct CSV::FieldInfo index=0, line=3, header=nil>]
# [" 2 ", #<struct CSV::FieldInfo index=1, line=3, header=nil>]
# Each CSV::Info object shows:
# - The 0-based field index.
# - The 1-based line index.
# - The field header, if any.
#
# ===== Stored \Converters
#
# A converter may be given a name and stored in a structure where
# the parsing methods can find it by name.
#
# The storage structure for field converters is the \Hash CSV::Converters.
# It has several built-in converter procs:
# - <tt>:integer</tt>: converts each \String-embedded integer into a true \Integer.
# - <tt>:float</tt>: converts each \String-embedded float into a true \Float.
# - <tt>:date</tt>: converts each \String-embedded date into a true \Date.
# - <tt>:date_time</tt>: converts each \String-embedded date-time into a true \DateTime
# .
# This example creates a converter proc, then stores it:
# strip_converter = proc {|field| field.strip }
# CSV::Converters[:strip] = strip_converter
# Then the parsing method call can refer to the converter
# by its name, <tt>:strip</tt>:
# string = " foo , 0 \n bar , 1 \n baz , 2 \n"
# array = CSV.parse(string, converters: :strip)
# array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# The storage structure for header converters is the \Hash CSV::HeaderConverters,
# which works in the same way.
# It also has built-in converter procs:
# - <tt>:downcase</tt>: Downcases each header.
# - <tt>:symbol</tt>: Converts each header to a \Symbol.
#
# There is no such storage structure for write headers.
#
# ===== Converter Lists
#
# A _converter_ _list_ is an \Array that may include any assortment of:
# - Converter procs.
# - Names of stored converters.
# - Nested converter lists.
#
# Examples:
# numeric_converters = [:integer, :float]
# date_converters = [:date, :date_time]
# [numeric_converters, strip_converter]
# [strip_converter, date_converters, :float]
#
# Like a converter proc, a converter list may be named and stored in either
# \CSV::Converters or CSV::HeaderConverters:
# CSV::Converters[:custom] = [strip_converter, date_converters, :float]
# CSV::HeaderConverters[:custom] = [:downcase, :symbol]
#
# There are two built-in converter lists:
# CSV::Converters[:numeric] # => [:integer, :float]
# CSV::Converters[:all] # => [:date_time, :numeric]
#
# ==== Field \Converters
#
# With no conversion, all parsed fields in all rows become Strings:
# string = "foo,0\nbar,1\nbaz,2\n"
# ary = CSV.parse(string)
# ary # => # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# When you specify a field converter, each parsed field is passed to the converter;
# its return value becomes the stored value for the field.
# A converter might, for example, convert an integer embedded in a \String
# into a true \Integer.
# (In fact, that's what built-in field converter +:integer+ does.)
#
# There are three ways to use field \converters.
#
# - Using option {converters}[#class-CSV-label-Option+converters] with a parsing method:
# ary = CSV.parse(string, converters: :integer)
# ary # => [0, 1, 2] # => [["foo", 0], ["bar", 1], ["baz", 2]]
# - Using option {converters}[#class-CSV-label-Option+converters] with a new \CSV instance:
# csv = CSV.new(string, converters: :integer)
# # Field converters in effect:
# csv.converters # => [:integer]
# csv.read # => [["foo", 0], ["bar", 1], ["baz", 2]]
# - Using method #convert to add a field converter to a \CSV instance:
# csv = CSV.new(string)
# # Add a converter.
# csv.convert(:integer)
# csv.converters # => [:integer]
# csv.read # => [["foo", 0], ["bar", 1], ["baz", 2]]
#
# Installing a field converter does not affect already-read rows:
# csv = CSV.new(string)
# csv.shift # => ["foo", "0"]
# # Add a converter.
# csv.convert(:integer)
# csv.converters # => [:integer]
# csv.read # => [["bar", 1], ["baz", 2]]
#
# There are additional built-in \converters, and custom \converters are also supported.
#
# ===== Built-In Field \Converters
#
# The built-in field converters are in \Hash CSV::Converters:
# - Each key is a field converter name.
# - Each value is one of:
# - A \Proc field converter.
# - An \Array of field converter names.
#
# Display:
# CSV::Converters.each_pair do |name, value|
# if value.kind_of?(Proc)
# p [name, value.class]
# else
# p [name, value]
# end
# end
# Output:
# [:integer, Proc]
# [:float, Proc]
# [:numeric, [:integer, :float]]
# [:date, Proc]
# [:date_time, Proc]
# [:all, [:date_time, :numeric]]
#
# Each of these converters transcodes values to UTF-8 before attempting conversion.
# If a value cannot be transcoded to UTF-8 the conversion will
# fail and the value will remain unconverted.
#
# Converter +:integer+ converts each field that Integer() accepts:
# data = '0,1,2,x'
# # Without the converter
# csv = CSV.parse_line(data)
# csv # => ["0", "1", "2", "x"]
# # With the converter
# csv = CSV.parse_line(data, converters: :integer)
# csv # => [0, 1, 2, "x"]
#
# Converter +:float+ converts each field that Float() accepts:
# data = '1.0,3.14159,x'
# # Without the converter
# csv = CSV.parse_line(data)
# csv # => ["1.0", "3.14159", "x"]
# # With the converter
# csv = CSV.parse_line(data, converters: :float)
# csv # => [1.0, 3.14159, "x"]
#
# Converter +:numeric+ converts with both +:integer+ and +:float+..
#
# Converter +:date+ converts each field that Date::parse accepts:
# data = '2001-02-03,x'
# # Without the converter
# csv = CSV.parse_line(data)
# csv # => ["2001-02-03", "x"]
# # With the converter
# csv = CSV.parse_line(data, converters: :date)
# csv # => [#<Date: 2001-02-03 ((2451944j,0s,0n),+0s,2299161j)>, "x"]
#
# Converter +:date_time+ converts each field that DateTime::parse accepts:
# data = '2020-05-07T14:59:00-05:00,x'
# # Without the converter
# csv = CSV.parse_line(data)
# csv # => ["2020-05-07T14:59:00-05:00", "x"]
# # With the converter
# csv = CSV.parse_line(data, converters: :date_time)
# csv # => [#<DateTime: 2020-05-07T14:59:00-05:00 ((2458977j,71940s,0n),-18000s,2299161j)>, "x"]
#
# Converter +:numeric+ converts with both +:date_time+ and +:numeric+..
#
# As seen above, method #convert adds \converters to a \CSV instance,
# and method #converters returns an \Array of the \converters in effect:
# csv = CSV.new('0,1,2')
# csv.converters # => []
# csv.convert(:integer)
# csv.converters # => [:integer]
# csv.convert(:date)
# csv.converters # => [:integer, :date]
#
# ===== Custom Field \Converters
#
# You can define a custom field converter:
# strip_converter = proc {|field| field.strip }
# string = " foo , 0 \n bar , 1 \n baz , 2 \n"
# array = CSV.parse(string, converters: strip_converter)
# array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
# You can register the converter in \Converters \Hash,
# which allows you to refer to it by name:
# CSV::Converters[:strip] = strip_converter
# string = " foo , 0 \n bar , 1 \n baz , 2 \n"
# array = CSV.parse(string, converters: :strip)
# array # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
#
# ==== Header \Converters
#
# Header converters operate only on headers (and not on other rows).
#
# There are three ways to use header \converters;
# these examples use built-in header converter +:dowhcase+,
# which downcases each parsed header.
#
# - Option +header_converters+ with a singleton parsing method:
# string = "Name,Count\nFoo,0\n,Bar,1\nBaz,2"
# tbl = CSV.parse(string, headers: true, header_converters: :downcase)
# tbl.class # => CSV::Table
# tbl.headers # => ["name", "count"]
#
# - Option +header_converters+ with a new \CSV instance:
# csv = CSV.new(string, header_converters: :downcase)
# # Header converters in effect:
# csv.header_converters # => [:downcase]
# tbl = CSV.parse(string, headers: true)
# tbl.headers # => ["Name", "Count"]
#
# - Method #header_convert adds a header converter to a \CSV instance:
# csv = CSV.new(string)
# # Add a header converter.
# csv.header_convert(:downcase)
# csv.header_converters # => [:downcase]
# tbl = CSV.parse(string, headers: true)
# tbl.headers # => ["Name", "Count"]
#
# ===== Built-In Header \Converters
#
# The built-in header \converters are in \Hash CSV::HeaderConverters.
# The keys there are the names of the \converters:
# CSV::HeaderConverters.keys # => [:downcase, :symbol]
#
# Converter +:downcase+ converts each header by downcasing it:
# string = "Name,Count\nFoo,0\n,Bar,1\nBaz,2"
# tbl = CSV.parse(string, headers: true, header_converters: :downcase)
# tbl.class # => CSV::Table
# tbl.headers # => ["name", "count"]
#
# Converter +:symbol+ converts each header by making it into a \Symbol:
# string = "Name,Count\nFoo,0\n,Bar,1\nBaz,2"
# tbl = CSV.parse(string, headers: true, header_converters: :symbol)
# tbl.headers # => [:name, :count]
# Details:
# - Strips leading and trailing whitespace.
# - Downcases the header.
# - Replaces embedded spaces with underscores.
# - Removes non-word characters.
# - Makes the string into a \Symbol.
#
# ===== Custom Header \Converters
#
# You can define a custom header converter:
# upcase_converter = proc {|header| header.upcase }
# string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
# table = CSV.parse(string, headers: true, header_converters: upcase_converter)
# table # => #<CSV::Table mode:col_or_row row_count:4>
# table.headers # => ["NAME", "VALUE"]
# You can register the converter in \HeaderConverters \Hash,
# which allows you to refer to it by name:
# CSV::HeaderConverters[:upcase] = upcase_converter
# table = CSV.parse(string, headers: true, header_converters: :upcase)
# table # => #<CSV::Table mode:col_or_row row_count:4>
# table.headers # => ["NAME", "VALUE"]
#
# ===== Write \Converters
#
# When you specify a write converter for generating \CSV,
# each field to be written is passed to the converter;
# its return value becomes the new value for the field.
# A converter might, for example, strip whitespace from a field.
#
# Using no write converter (all fields unmodified):
# output_string = CSV.generate do |csv|
# csv << [' foo ', 0]
# csv << [' bar ', 1]
# csv << [' baz ', 2]
# end
# output_string # => " foo ,0\n bar ,1\n baz ,2\n"
# Using option +write_converters+ with two custom write converters:
# strip_converter = proc {|field| field.respond_to?(:strip) ? field.strip : field }
# upcase_converter = proc {|field| field.respond_to?(:upcase) ? field.upcase : field }
# write_converters = [strip_converter, upcase_converter]
# output_string = CSV.generate(write_converters: write_converters) do |csv|
# csv << [' foo ', 0]
# csv << [' bar ', 1]
# csv << [' baz ', 2]
# end

# === Character Encodings (M17n or Multilingualization)
#
# This new CSV parser is m17n savvy. The parser works in the Encoding of the IO
# or String object being read from or written to. Your data is never transcoded
# (unless you ask Ruby to transcode it for you) and will literally be parsed in
# the Encoding it is in. Thus CSV will return Arrays or Rows of Strings in the
# Encoding of your data. This is accomplished by transcoding the parser itself
# into your Encoding.
#
# Some transcoding must take place, of course, to accomplish this multiencoding
# support. For example, <tt>:col_sep</tt>, <tt>:row_sep</tt>, and
# <tt>:quote_char</tt> must be transcoded to match your data. Hopefully this
# makes the entire process feel transparent, since CSV's defaults should just
# magically work for your data. However, you can set these values manually in
# the target Encoding to avoid the translation.
#
# It's also important to note that while all of CSV's core parser is now
# Encoding agnostic, some features are not. For example, the built-in
# converters will try to transcode data to UTF-8 before making conversions.
# Again, you can provide custom converters that are aware of your Encodings to
# avoid this translation. It's just too hard for me to support native
# conversions in all of Ruby's Encodings.
#
# Anyway, the practical side of this is simple: make sure IO and String objects
# passed into CSV have the proper Encoding set and everything should just work.
# CSV methods that allow you to open IO objects (CSV::foreach(), CSV::open(),
# CSV::read(), and CSV::readlines()) do allow you to specify the Encoding.
#
# One minor exception comes when generating CSV into a String with an Encoding
# that is not ASCII compatible. There's no existing data for CSV to use to
# prepare itself and thus you will probably need to manually specify the desired
# Encoding for most of those cases. It will try to guess using the fields in a
# row of output though, when using CSV::generate_line() or Array#to_csv().
#
# I try to point out any other Encoding issues in the documentation of methods
# as they come up.
#
# This has been tested to the best of my ability with all non-"dummy" Encodings
# Ruby ships with. However, it is brave new code and may have some bugs.
# Please feel free to {report}[mailto:james@grayproductions.net] any issues you
# find with it.

#
# == Overview
#
# The Common Gateway Interface (CGI) is a simple protocol for passing an HTTP
# request from a web server to a standalone program, and returning the output
# to the web browser. Basically, a CGI program is called with the parameters
# of the request passed in either in the environment (GET) or via $stdin
# (POST), and everything it prints to $stdout is returned to the client.
#
# This file holds the CGI class. This class provides functionality for
# retrieving HTTP request parameters, managing cookies, and generating HTML
# output.
#
# The file CGI::Session provides session management functionality; see that
# class for more details.
#
# See http://www.w3.org/CGI/ for more information on the CGI protocol.
#
# == Introduction
#
# CGI is a large class, providing several categories of methods, many of which
# are mixed in from other modules. Some of the documentation is in this class,
# some in the modules CGI::QueryExtension and CGI::HtmlExtension. See
# CGI::Cookie for specific information on handling cookies, and cgi/session.rb
# (CGI::Session) for information on sessions.
#
# For queries, CGI provides methods to get at environmental variables,
# parameters, cookies, and multipart request data. For responses, CGI provides
# methods for writing output and generating HTML.
#
# Read on for more details. Examples are provided at the bottom.
#
# == Queries
#
# The CGI class dynamically mixes in parameter and cookie-parsing
# functionality, environmental variable access, and support for
# parsing multipart requests (including uploaded files) from the
# CGI::QueryExtension module.
#
# === Environmental Variables
#
# The standard CGI environmental variables are available as read-only
# attributes of a CGI object. The following is a list of these variables:
#
#
# AUTH_TYPE HTTP_HOST REMOTE_IDENT
# CONTENT_LENGTH HTTP_NEGOTIATE REMOTE_USER
# CONTENT_TYPE HTTP_PRAGMA REQUEST_METHOD
# GATEWAY_INTERFACE HTTP_REFERER SCRIPT_NAME
# HTTP_ACCEPT HTTP_USER_AGENT SERVER_NAME
# HTTP_ACCEPT_CHARSET PATH_INFO SERVER_PORT
# HTTP_ACCEPT_ENCODING PATH_TRANSLATED SERVER_PROTOCOL
# HTTP_ACCEPT_LANGUAGE QUERY_STRING SERVER_SOFTWARE
# HTTP_CACHE_CONTROL REMOTE_ADDR
# HTTP_FROM REMOTE_HOST
#
#
# For each of these variables, there is a corresponding attribute with the
# same name, except all lower case and without a preceding HTTP_.
# +content_length+ and +server_port+ are integers; the rest are strings.
#
# === Parameters
#
# The method #params() returns a hash of all parameters in the request as
# name/value-list pairs, where the value-list is an Array of one or more
# values. The CGI object itself also behaves as a hash of parameter names
# to values, but only returns a single value (as a String) for each
# parameter name.
#
# For instance, suppose the request contains the parameter
# "favourite_colours" with the multiple values "blue" and "green". The
# following behavior would occur:
#
# cgi.params["favourite_colours"] # => ["blue", "green"]
# cgi["favourite_colours"] # => "blue"
#
# If a parameter does not exist, the former method will return an empty
# array, the latter an empty string. The simplest way to test for existence
# of a parameter is by the #has_key? method.
#
# === Cookies
#
# HTTP Cookies are automatically parsed from the request. They are available
# from the #cookies() accessor, which returns a hash from cookie name to
# CGI::Cookie object.
#
# === Multipart requests
#
# If a request's method is POST and its content type is multipart/form-data,
# then it may contain uploaded files. These are stored by the QueryExtension
# module in the parameters of the request. The parameter name is the name
# attribute of the file input field, as usual. However, the value is not
# a string, but an IO object, either an IOString for small files, or a
# Tempfile for larger ones. This object also has the additional singleton
# methods:
#
# #local_path():: the path of the uploaded file on the local filesystem
# #original_filename():: the name of the file on the client computer
# #content_type():: the content type of the file
#
# == Responses
#
# The CGI class provides methods for sending header and content output to
# the HTTP client, and mixes in methods for programmatic HTML generation
# from CGI::HtmlExtension and CGI::TagMaker modules. The precise version of HTML
# to use for HTML generation is specified at object creation time.
#
# === Writing output
#
# The simplest way to send output to the HTTP client is using the #out() method.
# This takes the HTTP headers as a hash parameter, and the body content
# via a block. The headers can be generated as a string using the #http_header()
# method. The output stream can be written directly to using the #print()
# method.
#
# === Generating HTML
#
# Each HTML element has a corresponding method for generating that
# element as a String. The name of this method is the same as that
# of the element, all lowercase. The attributes of the element are
# passed in as a hash, and the body as a no-argument block that evaluates
# to a String. The HTML generation module knows which elements are
# always empty, and silently drops any passed-in body. It also knows
# which elements require matching closing tags and which don't. However,
# it does not know what attributes are legal for which elements.
#
# There are also some additional HTML generation methods mixed in from
# the CGI::HtmlExtension module. These include individual methods for the
# different types of form inputs, and methods for elements that commonly
# take particular attributes where the attributes can be directly specified
# as arguments, rather than via a hash.
#
# === Utility HTML escape and other methods like a function.
#
# There are some utility tool defined in cgi/util.rb .
# And when include, you can use utility methods like a function.
#
# == Examples of use
#
# === Get form values
#
# require "cgi"
# cgi = CGI.new
# value = cgi['field_name'] # <== value string for 'field_name'
# # if not 'field_name' included, then return "".
# fields = cgi.keys # <== array of field names
#
# # returns true if form has 'field_name'
# cgi.has_key?('field_name')
# cgi.has_key?('field_name')
# cgi.include?('field_name')
#
# CAUTION! cgi['field_name'] returned an Array with the old
# cgi.rb(included in Ruby 1.6)
#
# === Get form values as hash
#
# require "cgi"
# cgi = CGI.new
# params = cgi.params
#
# cgi.params is a hash.
#
# cgi.params['new_field_name'] = ["value"] # add new param
# cgi.params['field_name'] = ["new_value"] # change value
# cgi.params.delete('field_name') # delete param
# cgi.params.clear # delete all params
#
#
# === Save form values to file
#
# require "pstore"
# db = PStore.new("query.db")
# db.transaction do
# db["params"] = cgi.params
# end
#
#
# === Restore form values from file
#
# require "pstore"
# db = PStore.new("query.db")
# db.transaction do
# cgi.params = db["params"]
# end
#
#
# === Get multipart form values
#
# require "cgi"
# cgi = CGI.new
# value = cgi['field_name'] # <== value string for 'field_name'
# value.read # <== body of value
# value.local_path # <== path to local file of value
# value.original_filename # <== original filename of value
# value.content_type # <== content_type of value
#
# and value has StringIO or Tempfile class methods.
#
# === Get cookie values
#
# require "cgi"
# cgi = CGI.new
# values = cgi.cookies['name'] # <== array of 'name'
# # if not 'name' included, then return [].
# names = cgi.cookies.keys # <== array of cookie names
#
# and cgi.cookies is a hash.
#
# === Get cookie objects
#
# require "cgi"
# cgi = CGI.new
# for name, cookie in cgi.cookies
# cookie.expires = Time.now + 30
# end
# cgi.out("cookie" => cgi.cookies) {"string"}
#
# cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... }
#
# require "cgi"
# cgi = CGI.new
# cgi.cookies['name'].expires = Time.now + 30
# cgi.out("cookie" => cgi.cookies['name']) {"string"}
#
# === Print http header and html string to $DEFAULT_OUTPUT ($>)
#
# require "cgi"
# cgi = CGI.new("html4") # add HTML generation methods
# cgi.out do
# cgi.html do
# cgi.head do
# cgi.title { "TITLE" }
# end +
# cgi.body do
# cgi.form("ACTION" => "uri") do
# cgi.p do
# cgi.textarea("get_text") +
# cgi.br +
# cgi.submit
# end
# end +
# cgi.pre do
# CGI.escapeHTML(
# "params: #{cgi.params.inspect}\n" +
# "cookies: #{cgi.cookies.inspect}\n" +
# ENV.collect do |key, value|
# "#{key} --> #{value}\n"
# end.join("")
# )
# end
# end
# end
# end
#
# # add HTML generation methods
# CGI.new("html3") # html3.2
# CGI.new("html4") # html4.01 (Strict)
# CGI.new("html4Tr") # html4.01 Transitional
# CGI.new("html4Fr") # html4.01 Frameset
# CGI.new("html5") # html5
#
# === Some utility methods
#
# require 'cgi/util'
# CGI.escapeHTML('Usage: foo "bar" <baz>')
#
#
# === Some utility methods like a function
#
# require 'cgi/util'
# include CGI::Util

#
# pp(obj) #=> obj
# pp obj #=> obj
# pp(obj1, obj2, ...) #=> [obj1, obj2, ...]
# pp() #=> nil
#
# Output <tt>obj(s)</tt> to <tt>$></tt> in pretty printed format.
#
# It returns <tt>obj(s)</tt>.
#
##
# == Output Customization
#
# To define a customized pretty printing function for your classes,
# redefine method <code>#pretty_print(pp)</code> in the class.
#
# <code>#pretty_print</code> takes the +pp+ argument, which is an instance of the PP class.

# = ERB -- Ruby Templating
#
# == Introduction
#
# ERB provides an easy to use but powerful templating system for Ruby. Using
# ERB, actual Ruby code can be added to any plain text document for the
# purposes of generating document information details and/or flow control.
#
# A very simple example is this:
#
# require 'erb'
#
# x = 42
# template = ERB.new <<-EOF
# The value of x is: <%= x %>
# EOF
# puts template.result(binding)
#
# <em>Prints:</em> The value of x is: 42
#
# More complex examples are given below.
#
#
# == Recognized Tags
#
# ERB recognizes certain tags in the provided template and converts them based
# on the rules below:
#
# <% Ruby code -- inline with output %>
# <%= Ruby expression -- replace with result %>
# <%# comment -- ignored -- useful in testing %>
# % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)
# %% replaced with % if first thing on a line and % processing is used
# <%% or %%> -- replace with <% or %> respectively
#
# All other text is passed through ERB filtering unchanged.
#
#
# == Options
#
# There are several settings you can change when you use ERB:
# * the nature of the tags that are recognized;
# * the binding used to resolve local variables in the template.
#
# See the ERB.new and ERB#result methods for more detail.
#
# == Character encodings
#
# ERB (or Ruby code generated by ERB) returns a string in the same
# character encoding as the input string. When the input string has
# a magic comment, however, it returns a string in the encoding specified
# by the magic comment.
#
# # -*- coding: utf-8 -*-
# require 'erb'
#
# template = ERB.new <<EOF
# <%#-*- coding: Big5 -*-%>
# \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>.
# EOF
# puts template.result
#
# <em>Prints:</em> \_\_ENCODING\_\_ is Big5.
#
#
# == Examples
#
# === Plain Text
#
# ERB is useful for any generic templating situation. Note that in this example, we use the
# convenient "% at start of line" tag, and we quote the template literally with
# <tt>%q{...}</tt> to avoid trouble with the backslash.
#
# require "erb"
#
# # Create template.

# === Ruby in HTML
#
# ERB is often used in <tt>.rhtml</tt> files (HTML with embedded Ruby). Notice the need in
# this example to provide a special binding when the template is run, so that the instance
# variables in the Product object can be resolved.
#
# require "erb"
#
# # Build template data class.
# class Product
# def initialize( code, name, desc, cost )
# @code = code
# @name = name
# @desc = desc
# @cost = cost
#
# @features = [ ]
# end
#
# def add_feature( feature )
# @features << feature
# end
#
# # Support templating of member data.
# def get_binding
# binding
# end
#
# # ...
# end
#
# # Create template.

#
# == Notes
#
# There are a variety of templating solutions available in various Ruby projects.
# For example, RDoc, distributed with Ruby, uses its own template engine, which
# can be reused elsewhere.
#
# Other popular engines could be found in the corresponding
# {Category}[https://www.ruby-toolbox.com/categories/template_engines] of
# The Ruby Toolbox.

# ERB::Compiler
class ERB
# = ERB::Compiler
#
# Compiles ERB templates into Ruby code; the compiled code produces the
# template result when evaluated. ERB::Compiler provides hooks to define how
# generated output is handled.
#
# Internally ERB does something like this to generate the code returned by
# ERB#src:
#
# compiler = ERB::Compiler.new('<>')
# compiler.pre_cmd = ["_erbout=+''"]
# compiler.put_cmd = "_erbout.<<"
# compiler.insert_cmd = "_erbout.<<"
# compiler.post_cmd = ["_erbout"]
#
# code, enc = compiler.compile("Got <%= obj %>!\n")
# puts code
#
# <i>Generates</i>:
#
# #coding:UTF-8
# _erbout=+''; _erbout.<< "Got ".freeze; _erbout.<<(( obj ).to_s); _erbout.<< "!\n".freeze; _erbout
#
# By default the output is sent to the print method. For example:
#
# compiler = ERB::Compiler.new('<>')
# code, enc = compiler.compile("Got <%= obj %>!\n")
# puts code
#
# <i>Generates</i>:
#
# #coding:UTF-8
# print "Got ".freeze; print(( obj ).to_s); print "!\n".freeze
#
# == Evaluation
#
# The compiled code can be used in any context where the names in the code
# correctly resolve. Using the last example, each of these print 'Got It!'
#
# Evaluate using a variable:
#
# obj = 'It'
# eval code
#
# Evaluate using an input:
#
# mod = Module.new
# mod.module_eval %{
# def get(obj)
# #{code}
# end
# }
# extend mod
# get('It')
#
# Evaluate using an accessor:
#
# klass = Class.new Object
# klass.class_eval %{
# attr_accessor :obj
# def initialize(obj)
# @obj = obj
# end
# def get_it
# #{code}
# end
# }
# klass.new('It').get_it

# ERB
class ERB
#
# Constructs a new ERB object with the template specified in _str_.
#
# An ERB object works by building a chunk of Ruby code that will output
# the completed template when run.
#
# If _trim_mode_ is passed a String containing one or more of the following
# modifiers, ERB will adjust its code generation as listed:
#
# % enables Ruby code processing for lines beginning with %
# <> omit newline for lines starting with <% and ending in %>
# > omit newline for lines ending in %>
# - omit blank lines ending in -%>
#
# _eoutvar_ can be used to set the name of the variable ERB will build up
# its output in. This is useful when you need to run multiple ERB
# templates through the same binding and/or when you want to control where
# output ends up. Pass the name of the variable to be used inside a String.
#
# === Example
#
# require "erb"
#
# # build data class
# class Listings
# PRODUCT = { :name => "Chicken Fried Steak",
# :desc => "A well messages pattie, breaded and fried.",
# :cost => 9.95 }
#
# attr_reader :product, :price
#
# def initialize( product = "", price = "" )
# @product = product
# @price = price
# end
#
# def build
# b = binding
# # create and run templates, filling member data variables
# ERB.new(<<-'END_PRODUCT'.gsub(/^\s+/, ""), trim_mode: "", eoutvar: "@product").result b
# <%= PRODUCT[:name] %>
# <%= PRODUCT[:desc] %>
# END_PRODUCT
# ERB.new(<<-'END_PRICE'.gsub(/^\s+/, ""), trim_mode: "", eoutvar: "@price").result b
# <%= PRODUCT[:name] %> -- <%= PRODUCT[:cost] %>
# <%= PRODUCT[:desc] %>
# END_PRICE
# end
# end
#
# # setup template data
# listings = Listings.new

YAML = Psych # :nodoc:
# YAML Ain't Markup Language
#
# This module provides a Ruby interface for data serialization in YAML format.
#
# The YAML module is an alias of Psych, the YAML engine for Ruby.
#
# == Usage
#
# Working with YAML can be very simple, for example:
#
# require 'yaml'
# # Parse a YAML string
# YAML.load("--- foo") #=> "foo"
#
# # Emit some YAML
# YAML.dump("foo") # => "--- foo\n...\n"
# { :a => 'b'}.to_yaml # => "---\n:a: b\n"
#
# As the implementation is provided by the Psych library, detailed documentation
# can be found in that library's docs (also part of standard library).
#
# == Security
#
# Do not use YAML to load untrusted data. Doing so is unsafe and could allow
# malicious input to execute arbitrary code inside your application. Please see
# doc/security.rdoc for more information.
#
# == History
#
# Syck was the original YAML implementation in Ruby's standard library
# developed by why the lucky stiff.
#
# You can still use Syck, if you prefer, for parsing and emitting YAML, but you
# must install the 'syck' gem now in order to use it.
#
# In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was
# completely removed with the release of Ruby 2.0.0.
#
# == More info
#
# For more advanced details on the implementation see Psych, and also check out
# http://yaml.org for spec details and other helpful information.
#
# Psych is maintained by Aaron Patterson on github: https://github.com/ruby/psych
#
# Syck can also be found on github: https://github.com/ruby/syck

# The GetoptLong class allows you to parse command line options similarly to
# the GNU getopt_long() C library call. Note, however, that GetoptLong is a
# pure Ruby implementation.
#
# GetoptLong allows for POSIX-style options like <tt>--file</tt> as well
# as single letter options like <tt>-f</tt>
#
# The empty option <tt>--</tt> (two minus symbols) is used to end option
# processing. This can be particularly important if options have optional
# arguments.
#
# Here is a simple example of usage:
#
# require 'getoptlong'
#
# opts = GetoptLong.new(
# [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
# [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],
# [ '--name', GetoptLong::OPTIONAL_ARGUMENT ]
# )
#
# dir = nil
# name = nil
# repetitions = 1
# opts.each do |opt, arg|
# case opt
# when '--help'
# puts <<-EOF
# hello [OPTION] ... DIR
#
# -h, --help:
# show help
#
# --repeat x, -n x:
# repeat x times
#
# --name [name]:
# greet user by name, if name not supplied default is John
#
# DIR: The directory in which to issue the greeting.
# EOF
# when '--repeat'
# repetitions = arg.to_i

# The supplied value must be a member of GetoptLong::ORDERINGS. It alters
# the processing of options as follows:
#
# <b>REQUIRE_ORDER</b> :
#
# Options are required to occur before non-options.
#
# Processing of options ends as soon as a word is encountered that has not
# been preceded by an appropriate option flag.
#
# For example, if -a and -b are options which do not take arguments,
# parsing command line arguments of '-a one -b two' would result in
# 'one', '-b', 'two' being left in ARGV, and only ('-a', '') being
# processed as an option/arg pair.
#
# This is the default ordering, if the environment variable
# POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)
#
# <b>PERMUTE</b> :
#
# Options can occur anywhere in the command line parsed. This is the
# default behavior.
#
# Every sequence of words which can be interpreted as an option (with or
# without argument) is treated as an option; non-option words are skipped.
#
# For example, if -a does not require an argument and -b optionally takes
# an argument, parsing '-a one -b two three' would result in ('-a','') and
# ('-b', 'two') being processed as option/arg pairs, and 'one','three'
# being left in ARGV.
#
# If the ordering is set to PERMUTE but the environment variable
# POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for
# compatibility with GNU getopt_long.
#
# <b>RETURN_IN_ORDER</b> :
#
# All words on the command line are processed as options. Words not
# preceded by a short or long option flag are passed as arguments
# with an option of '' (empty string).
#
# For example, if -a requires an argument but -b does not, a command line
# of '-a one -b two three' would result in option/arg pairs of ('-a', 'one')
# ('-b', ''), ('', 'two'), ('', 'three') being processed.

# For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n
# unit lower triangular matrix L, an n-by-n upper triangular matrix U,
# and a m-by-m permutation matrix P so that L*U = P*A.
# If m < n, then L is m-by-m and U is m-by-n.
#
# The LUP decomposition with pivoting always exists, even if the matrix is
# singular, so the constructor will never fail. The primary use of the
# LU decomposition is in the solution of square systems of simultaneous
# linear equations. This will fail if singular? returns true.

# == Synopsis
#
# require 'timeout'
# status = Timeout::timeout(5) {
# # Something that should be interrupted if it takes more than 5 seconds...
# }
#
# == Description
#
# Timeout provides a way to auto-terminate a potentially long-running
# operation if it hasn't finished in a fixed amount of time.
#
# Previous versions didn't use a module for namespacing, however
# #timeout is provided for backwards compatibility. You
# should prefer Timeout.timeout instead.

# Default service location uses the following steps:

# listen for a reply.
# 3. The RingServer receives the UDP packet and connects back to the

# A RingServer requires a TupleSpace:
#
# ts = Rinda::TupleSpace.new
# rs = Rinda::RingServer.new
#
# RingServer can also listen on multicast addresses for announcements. This
# allows multiple RingServers to run on the same host. To use network
# broadcast and multicast:

# with keys formed by preceding the component names with a colon.
#
# If an Array is used, the components must be passed in the
# order <code>[userinfo, host, port, path, typecode]</code>.
#
# If the path supplied is absolute, it will be escaped in order to
# make it absolute in the URI.
#
# Examples:
#
# require 'uri'
#
# uri1 = URI::FTP.build(['user:password', 'ftp.example.com', nil,
# '/path/file.zip', 'i'])

# Ripper is a Ruby script parser.
#
# You can get information from the parser with event-based style.
# Information such as abstract syntax trees or simple lexical analysis of the
# Ruby program.
#
# == Usage
#
# Ripper provides an easy interface for parsing your program into a symbolic
# expression tree (or S-expression).
#
# Understanding the output of the parser may come as a challenge, it's
# recommended you use PP to format the output for legibility.
#
# require 'ripper'
# require 'pp'
#
# pp Ripper.sexp('def hello(world) "Hello, #{world}!"; end')
# #=> [:program,
# [[:def,
# [:@ident, "hello", [1, 4]],
# [:paren,
# [:params, [[:@ident, "world", [1, 10]]], nil, nil, nil, nil, nil, nil]],
# [:bodystmt,
# [[:string_literal,
# [:string_content,
# [:@tstring_content, "Hello, ", [1, 18]],
# [:string_embexpr, [[:var_ref, [:@ident, "world", [1, 27]]]]],
# [:@tstring_content, "!", [1, 33]]]]],
# nil,
# nil,
# nil]]]]
#
# You can see in the example above, the expression starts with +:program+.
#
# From here, a method definition at +:def+, followed by the method's identifier
# <code>:@ident</code>. After the method's identifier comes the parentheses
# +:paren+ and the method parameters under +:params+.
#
# Next is the method body, starting at +:bodystmt+ (+stmt+ meaning statement),
# which contains the full definition of the method.
#
# In our case, we're simply returning a String, so next we have the
# +:string_literal+ expression.
#
# Within our +:string_literal+ you'll notice two <code>@tstring_content</code>,
# this is the literal part for <code>Hello, </code> and <code>!</code>. Between
# the two <code>@tstring_content</code> statements is a +:string_embexpr+,
# where _embexpr_ is an embedded expression. Our expression consists of a local
# variable, or +var_ref+, with the identifier (<code>@ident</code>) of +world+.

module Net
#
# Net::IMAP implements Internet Message Access Protocol (IMAP) client
# functionality. The protocol is described in [IMAP].
#
# == IMAP Overview
#
# An IMAP client connects to a server, and then authenticates
# itself using either #authenticate() or #login(). Having
# authenticated itself, there is a range of commands
# available to it. Most work with mailboxes, which may be
# arranged in an hierarchical namespace, and each of which
# contains zero or more messages. How this is implemented on
# the server is implementation-dependent; on a UNIX server, it
# will frequently be implemented as files in mailbox format
# within a hierarchy of directories.
#
# To work on the messages within a mailbox, the client must
# first select that mailbox, using either #select() or (for
# read-only access) #examine(). Once the client has successfully
# selected a mailbox, they enter _selected_ state, and that
# mailbox becomes the _current_ mailbox, on which mail-item
# related commands implicitly operate.
#
# Messages have two sorts of identifiers: message sequence
# numbers and UIDs.
#
# Message sequence numbers number messages within a mailbox
# from 1 up to the number of items in the mailbox. If a new
# message arrives during a session, it receives a sequence
# number equal to the new size of the mailbox. If messages
# are expunged from the mailbox, remaining messages have their
# sequence numbers "shuffled down" to fill the gaps.
#
# UIDs, on the other hand, are permanently guaranteed not to
# identify another message within the same mailbox, even if
# the existing message is deleted. UIDs are required to
# be assigned in ascending (but not necessarily sequential)
# order within a mailbox; this means that if a non-IMAP client
# rearranges the order of mailitems within a mailbox, the
# UIDs have to be reassigned. An IMAP client thus cannot
# rearrange message orders.
#
# == Examples of Usage
#
# === List sender and subject of all recent messages in the default mailbox
#
# imap = Net::IMAP.new('mail.example.com')
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
# imap.examine('INBOX')
# imap.search(["RECENT"]).each do |message_id|
# envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
# puts "#{envelope.from[0].name}: \t#{envelope.subject}"
# end
#
# === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"
#
# imap = Net::IMAP.new('mail.example.com')
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
# imap.select('Mail/sent-mail')
# if not imap.list('Mail/', 'sent-apr03')
# imap.create('Mail/sent-apr03')
# end
# imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
# imap.copy(message_id, "Mail/sent-apr03")
# imap.store(message_id, "+FLAGS", [:Deleted])
# end
# imap.expunge
#
# == Thread Safety
#
# Net::IMAP supports concurrent threads. For example,
#
# imap = Net::IMAP.new("imap.foo.net", "imap2")
# imap.authenticate("cram-md5", "bar", "password")
# imap.select("inbox")
# fetch_thread = Thread.start { imap.fetch(1..-1, "UID") }
# search_result = imap.search(["BODY", "hello"])
# fetch_result = fetch_thread.value
# imap.disconnect
#
# This script invokes the FETCH command and the SEARCH command concurrently.
#
# == Errors
#
# An IMAP server can send three different types of responses to indicate
# failure:
#
# NO:: the attempted command could not be successfully completed. For
# instance, the username/password used for logging in are incorrect;
# the selected mailbox does not exist; etc.
#
# BAD:: the request from the client does not follow the server's
# understanding of the IMAP protocol. This includes attempting
# commands from the wrong client state; for instance, attempting
# to perform a SEARCH command without having SELECTed a current
# mailbox. It can also signal an internal server
# failure (such as a disk crash) has occurred.
#
# BYE:: the server is saying goodbye. This can be part of a normal
# logout sequence, and can be used as part of a login sequence
# to indicate that the server is (for some reason) unwilling
# to accept your connection. As a response to any other command,
# it indicates either that the server is shutting down, or that
# the server is timing out the client connection due to inactivity.
#
# These three error response are represented by the errors
# Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and
# Net::IMAP::ByeResponseError, all of which are subclasses of
# Net::IMAP::ResponseError. Essentially, all methods that involve
# sending a request to the server can generate one of these errors.
# Only the most pertinent instances have been documented below.
#
# Because the IMAP class uses Sockets for communication, its methods
# are also susceptible to the various errors that can occur when
# working with sockets. These are generally represented as
# Errno errors. For instance, any method that involves sending a
# request to the server and/or receiving a response from it could
# raise an Errno::EPIPE error if the network connection unexpectedly
# goes down. See the socket(7), ip(7), tcp(7), socket(2), connect(2),
# and associated man pages.
#
# Finally, a Net::IMAP::DataFormatError is thrown if low-level data
# is found to be in an incorrect format (for instance, when converting
# between UTF-8 and UTF-16), and Net::IMAP::ResponseParseError is
# thrown if a server response is non-parseable.

#
# BODY <string>:: messages that contain <string> within their body.
#
# CC <string>:: messages containing <string> in their CC field.
#
# FROM <string>:: messages that contain <string> in their FROM field.
#
# NEW:: messages with the \Recent, but not the \Seen, flag set.

# NOT <search-key>:: negate the following search key.
#
# OR <search-key> <search-key>:: "or" two search keys together.

# ON <date>:: messages with an internal date exactly equal to <date>,
# which has a format similar to 8-Aug-2002.
#
# SINCE <date>:: messages with an internal date on or after <date>.
#
# SUBJECT <string>:: messages with <string> in their subject.
#
# TO <string>:: messages with <string> in their TO field.

#
# == What is This Library?
#
# This library provides functionality to send internet
# mail via SMTP, the Simple Mail Transfer Protocol. For details of
# SMTP itself, see [RFC2821] (http://www.ietf.org/rfc/rfc2821.txt).
#
# == What is This Library NOT?
#
# This library does NOT provide functions to compose internet mails.
# You must create them by yourself. If you want better mail support,
# try RubyMail or TMail or search for alternatives in
# {RubyGems.org}[https://rubygems.org/] or {The Ruby
# Toolbox}[https://www.ruby-toolbox.com/].
#
# FYI: the official documentation on internet mail is: [RFC2822] (http://www.ietf.org/rfc/rfc2822.txt).
#
# == Examples
#
# === Sending Messages
#
# You must open a connection to an SMTP server before sending messages.
# The first argument is the address of your SMTP server, and the second
# argument is the port number. Using SMTP.start with a block is the simplest
# way to do this. This way, the SMTP connection is closed automatically
# after the block is executed.
#
# require 'net/smtp'
# Net::SMTP.start('your.smtp.server', 25) do |smtp|
# # Use the SMTP object smtp only in this block.
# end
#
# Replace 'your.smtp.server' with your SMTP server. Normally
# your system manager or internet provider supplies a server
# for you.
#
# Then you can send messages.
#
# msgstr = <<END_OF_MESSAGE
# From: Your Name <your@mail.address>
# To: Destination Address <someone@example.com>
# Subject: test message
# Date: Sat, 23 Jun 2001 16:26:43 +0900
# Message-Id: <unique.message.id.string@example.com>
#
# This is a test message.
# END_OF_MESSAGE
#
# require 'net/smtp'
# Net::SMTP.start('your.smtp.server', 25) do |smtp|
# smtp.send_message msgstr,
# 'your@mail.address',
# 'his_address@example.com'
# end
#
# === Closing the Session
#
# You MUST close the SMTP session after sending messages, by calling
# the #finish method:
#
# # using SMTP#finish
# smtp = Net::SMTP.start('your.smtp.server', 25)
# smtp.send_message msgstr, 'from@address', 'to@address'
# smtp.finish
#
# You can also use the block form of SMTP.start/SMTP#start. This closes
# the SMTP session automatically:
#
# # using block form of SMTP.start
# Net::SMTP.start('your.smtp.server', 25) do |smtp|
# smtp.send_message msgstr, 'from@address', 'to@address'
# end
#
# I strongly recommend this scheme. This form is simpler and more robust.
#
# === HELO domain
#
# In almost all situations, you must provide a third argument
# to SMTP.start/SMTP#start. This is the domain name which you are on
# (the host to send mail from). It is called the "HELO domain".
# The SMTP server will judge whether it should send or reject
# the SMTP session by inspecting the HELO domain.
#
# Net::SMTP.start('your.smtp.server', 25
# helo: 'mail.from.domain') { |smtp| ... }
#
# === SMTP Authentication
#
# The Net::SMTP class supports three authentication schemes;
# PLAIN, LOGIN and CRAM MD5. (SMTP Authentication: [RFC2554])
# To use SMTP authentication, pass extra arguments to
# SMTP.start/SMTP#start.
#
# # PLAIN
# Net::SMTP.start('your.smtp.server', 25
# user: 'Your Account', secret: 'Your Password', authtype: :plain)
# # LOGIN
# Net::SMTP.start('your.smtp.server', 25
# user: 'Your Account', secret: 'Your Password', authtype: :login)
#
# # CRAM MD5
# Net::SMTP.start('your.smtp.server', 25
# user: 'Your Account', secret: 'Your Password', authtype: :cram_md5)
#

# start(address, port = nil, helo = 'localhost', user = nil, secret = nil, authtype = nil) { |smtp| ... }
#
# Creates a new Net::SMTP object and connects to the server.
#
# This method is equivalent to:
#
# Net::SMTP.new(address, port).start(helo: helo_domain, user: account, secret: password, authtype: authtype, tls_verify: flag, tls_hostname: hostname)
#
# === Example
#
# Net::SMTP.start('your.smtp.server') do |smtp|
# smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
# end
#
# === Block Usage
#
# If called with a block, the newly-opened Net::SMTP object is yielded
# to the block, and automatically closed when the block finishes. If called
# without a block, the newly-opened Net::SMTP object is returned to
# the caller, and it is the caller's responsibility to close it when
# finished.
#
# === Parameters
#
# +address+ is the hostname or ip address of your smtp server.
#
# +port+ is the port to connect to; it defaults to port 25.
#
# +helo+ is the _HELO_ _domain_ provided by the client to the
# server (see overview comments); it defaults to 'localhost'.
#
# The remaining arguments are used for SMTP authentication, if required
# or desired. +user+ is the account name; +secret+ is your password
# or other authentication token; and +authtype+ is the authentication
# type, one of :plain, :login, or :cram_md5. See the discussion of
# SMTP Authentication in the overview notes.
# If +tls_verify+ is true, verify the server's certificate. The default is true.
# If the hostname in the server certificate is different from +address+,
# it can be specified with +tls_hostname+.
#
# === Errors
#
# This method may raise:
#
# * Net::SMTPAuthenticationError
# * Net::SMTPServerBusy
# * Net::SMTPSyntaxError
# * Net::SMTPFatalError
# * Net::SMTPUnknownError
# * Net::OpenTimeout
# * Net::ReadTimeout
# * IOError

# start(helo = 'localhost', user = nil, secret = nil, authtype = nil) { |smtp| ... }
#
# Opens a TCP connection and starts the SMTP session.
#
# === Parameters
#
# +helo+ is the _HELO_ _domain_ that you'll dispatch mails from; see
# the discussion in the overview notes.
#
# If both of +user+ and +secret+ are given, SMTP authentication
# will be attempted using the AUTH command. +authtype+ specifies
# the type of authentication to attempt; it must be one of
# :login, :plain, and :cram_md5. See the notes on SMTP Authentication
# in the overview.
# If +tls_verify+ is true, verify the server's certificate. The default is true.
# If the hostname in the server certificate is different from +address+,
# it can be specified with +tls_hostname+.
#
# === Block Usage
#
# When this methods is called with a block, the newly-started SMTP
# object is yielded to the block, and automatically closed after
# the block call finishes. Otherwise, it is the caller's
# responsibility to close the session when finished.
#
# === Example
#
# This is very similar to the class method SMTP.start.
#
# require 'net/smtp'
# smtp = Net::SMTP.new('smtp.mail.server', 25)
# smtp.start(helo: helo_domain, user: account, secret: password, authtype: authtype) do |smtp|
# smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
# end
#
# The primary use of this method (as opposed to SMTP.start)
# is probably to set debugging (#set_debug_output) or ESMTP
# (#esmtp=), which must be done before the session is
# started.
#
# === Errors
#
# If session has already been started, an IOError will be raised.
#
# This method may raise:
#
# * Net::SMTPAuthenticationError
# * Net::SMTPServerBusy
# * Net::SMTPSyntaxError
# * Net::SMTPFatalError
# * Net::SMTPUnknownError
# * Net::OpenTimeout
# * Net::ReadTimeout
# * IOError

# This class implements the File Transfer Protocol. If you have used a
# command-line FTP program, and are familiar with the commands, you will be
# able to use this class easily. Some extra features are included to take
# advantage of Ruby's style and strengths.
#
# == Example
#
# require 'net/ftp'
#
# === Example 1
#
# ftp = Net::FTP.new('example.com')
# ftp.login
# files = ftp.chdir('pub/lang/ruby/contrib')
# files = ftp.list('n*')
# ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
# ftp.close
#
# === Example 2
#
# Net::FTP.open('example.com') do |ftp|
# ftp.login
# files = ftp.chdir('pub/lang/ruby/contrib')
# files = ftp.list('n*')
# ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
# end
#
# == Major Methods
#
# The following are the methods most likely to be useful to users:
# - FTP.open
# - #getbinaryfile
# - #gettextfile
# - #putbinaryfile
# - #puttextfile
# - #chdir
# - #nlst
# - #size
# - #rename

#
# == What is This Library?
#
# This library provides functionality for retrieving
# email via POP3, the Post Office Protocol version 3. For details
# of POP3, see [RFC1939] (http://www.ietf.org/rfc/rfc1939.txt).
#
# == Examples
#
# === Retrieving Messages
#
# This example retrieves messages from the server and deletes them
# on the server.
#
# Messages are written to files named 'inbox/1', 'inbox/2', ....
# Replace 'pop.example.com' with your POP3 server address, and
# 'YourAccount' and 'YourPassword' with the appropriate account
# details.
#
# require 'net/pop'
#
# pop = Net::POP3.new('pop.example.com')
# pop.start('YourAccount', 'YourPassword') # (1)
# if pop.mails.empty?
# puts 'No mail.'
# else
# i = 0
# pop.each_mail do |m| # or "pop.mails.each ..." # (2)
# File.open("inbox/#{i}", 'w') do |f|
# f.write m.pop
# end
# m.delete
# i += 1
# end
# puts "#{pop.mails.size} mails popped."
# end
# pop.finish # (3)
#
# 1. Call Net::POP3#start and start POP session.
# 2. Access messages by using POP3#each_mail and/or POP3#mails.
# 3. Close POP session by calling POP3#finish or use the block form of #start.
#
# === Shortened Code
#
# The example above is very verbose. You can shorten the code by using
# some utility methods. First, the block form of Net::POP3.start can
# be used instead of POP3.new, POP3#start and POP3#finish.
#
# require 'net/pop'
#
# Net::POP3.start('pop.example.com', 110,
# 'YourAccount', 'YourPassword') do |pop|
# if pop.mails.empty?
# puts 'No mail.'
# else
# i = 0
# pop.each_mail do |m| # or "pop.mails.each ..."
# File.open("inbox/#{i}", 'w') do |f|
# f.write m.pop
# end
# m.delete
# i += 1
# end
# puts "#{pop.mails.size} mails popped."
# end
# end
#
# POP3#delete_all is an alternative for #each_mail and #delete.
#
# require 'net/pop'
#
# Net::POP3.start('pop.example.com', 110,
# 'YourAccount', 'YourPassword') do |pop|
# if pop.mails.empty?
# puts 'No mail.'
# else
# i = 1
# pop.delete_all do |m|
# File.open("inbox/#{i}", 'w') do |f|
# f.write m.pop
# end
# i += 1
# end
# end
# end
#
# And here is an even shorter example.
#
# require 'net/pop'
#
# i = 0
# Net::POP3.delete_all('pop.example.com', 110,
# 'YourAccount', 'YourPassword') do |m|
# File.open("inbox/#{i}", 'w') do |f|
# f.write m.pop
# end
# i += 1
# end
#
# === Memory Space Issues
#
# All the examples above get each message as one big string.
# This example avoids this.
#
# require 'net/pop'
#
# i = 1
# Net::POP3.delete_all('pop.example.com', 110,
# 'YourAccount', 'YourPassword') do |m|
# File.open("inbox/#{i}", 'w') do |f|
# m.pop do |chunk| # get a message little by little.
# f.write chunk
# end
# i += 1
# end
# end
#
# === Using APOP
#
# The net/pop library supports APOP authentication.
# To use APOP, use the Net::APOP class instead of the Net::POP3 class.
# You can use the utility method, Net::POP3.APOP(). For example:
#
# require 'net/pop'
#
# # Use APOP authentication if $isapop == true
# pop = Net::POP3.APOP($isapop).new('apop.example.com', 110)
# pop.start('YourAccount', 'YourPassword') do |pop|
# # Rest of the code is the same.
# end
#
# === Fetch Only Selected Mail Using 'UIDL' POP Command
#
# If your POP server provides UIDL functionality,
# you can grab only selected mails from the POP server.
# e.g.
#
# def need_pop?( id )
# # determine if we need pop this mail...
# end
#
# Net::POP3.start('pop.example.com', 110,
# 'Your account', 'Your password') do |pop|
# pop.mails.select { |m| need_pop?(m.unique_id) }.each do |m|
# do_something(m.pop)
# end
# end
#
# The POPMail#unique_id() method returns the unique-id of the message as a
# String. Normally the unique-id is a hash of the message.
#

# Utilities
#
# Returns the APOP class if +isapop+ is true; otherwise, returns
# the POP class. For example:
#
# # Example 1
# pop = Net::POP3::APOP($is_apop).new(addr, port)

# # Example 2
# Net::POP3::APOP($is_apop).start(addr, port) do |pop|

# yield m
# end
# end
#
# This method raises a POPAuthenticationError if authentication fails.
#
# === Example
#
# Net::POP3.foreach('pop.example.com', 110,

# Starts a POP3 session and deletes all messages on the server.
# If a block is given, each POPMail object is yielded to it before
# being deleted.
#
# This method raises a POPAuthenticationError if authentication fails.
#
# === Example
#
# Net::POP3.delete_all('pop.example.com', 110,
# 'YourAccount', 'YourPassword') do |m|
# file.write m.pop
# end
#
def POP3.delete_all(address, port = nil,
account = nil, password = nil,
isapop = false, &block)
start(address, port, account, password, isapop) {|pop|
pop.delete_all(&block)
}
end
# Opens a POP3 session, attempts authentication, and quits.
#
# This method raises POPAuthenticationError if authentication fails.
#
# === Example: normal POP3
#
# Net::POP3.auth_only('pop.example.com', 110,
# 'YourAccount', 'YourPassword')
#
# === Example: APOP
#
# Net::POP3.auth_only('pop.example.com', 110,

# == An HTTP client API for Ruby.
#
# Net::HTTP provides a rich library which can be used to build HTTP
# user-agents. For more details about HTTP see
# [RFC2616](http://www.ietf.org/rfc/rfc2616.txt).
#
# Net::HTTP is designed to work closely with URI. URI::HTTP#host,
# URI::HTTP#port and URI::HTTP#request_uri are designed to work with
# Net::HTTP.
#
# If you are only performing a few GET requests you should try OpenURI.
#
# == Simple Examples
#
# All examples assume you have loaded Net::HTTP with:
#
# require 'net/http'
#
# This will also require 'uri' so you don't need to require it separately.
#
# The Net::HTTP methods in the following section do not persist
# connections. They are not recommended if you are performing many HTTP
# requests.
#
# === GET
#
# Net::HTTP.get('example.com', '/index.html') # => String
#
# === GET by URI
#
# uri = URI('http://example.com/index.html?count=10')
# Net::HTTP.get(uri) # => String
#
# === GET with Dynamic Parameters
#
# uri = URI('http://example.com/index.html')
# params = { :limit => 10, :page => 3 }
# uri.query = URI.encode_www_form(params)
#
# res = Net::HTTP.get_response(uri)
# puts res.body if res.is_a?(Net::HTTPSuccess)
#
# === POST
#
# uri = URI('http://www.example.com/search.cgi')
# res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
# puts res.body
#
# === POST with Multiple Values
#
# uri = URI('http://www.example.com/search.cgi')
# res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
# puts res.body
#
# == How to use Net::HTTP
#
# The following example code can be used as the basis of an HTTP user-agent
# which can perform a variety of request types using persistent
# connections.
#
# uri = URI('http://example.com/some_path?query=string')
#
# Net::HTTP.start(uri.host, uri.port) do |http|
# request = Net::HTTP::Get.new uri
#
# response = http.request request # Net::HTTPResponse object
# end
#
# Net::HTTP::start immediately creates a connection to an HTTP server which
# is kept open for the duration of the block. The connection will remain
# open for multiple requests in the block if the server indicates it
# supports persistent connections.
#
# If you wish to re-use a connection across multiple HTTP requests without
# automatically closing it you can use ::new and then call #start and
# #finish manually.
#
# The request types Net::HTTP supports are listed below in the section "HTTP
# Request Classes".
#
# For all the Net::HTTP request objects and shortcut request methods you may
# supply either a String for the request path or a URI from which Net::HTTP
# will extract the request path.
#
# === Response Data
#
# uri = URI('http://example.com/index.html')

#
# === Following Redirection
#
# Each Net::HTTPResponse object belongs to a class for its response code.
#
# For example, all 2XX responses are instances of a Net::HTTPSuccess
# subclass, a 3XX response is an instance of a Net::HTTPRedirection
# subclass and a 200 response is an instance of the Net::HTTPOK class. For
# details of response classes, see the section "HTTP Response Classes"
# below.
#
# Using a case statement you can handle various types of responses properly:
#
# def fetch(uri_str, limit = 10)
# # You should choose a better exception.
# raise ArgumentError, 'too many HTTP redirects' if limit == 0
#
# response = Net::HTTP.get_response(URI(uri_str))
#
# case response
# when Net::HTTPSuccess then
# response
# when Net::HTTPRedirection then
# location = response['location']
# warn "redirected to #{location}"
# fetch(location, limit - 1)
# else
# response.value
# end
# end
#
# print fetch('http://www.ruby-lang.org')
#
# === POST
#
# A POST can be made using the Net::HTTP::Post request class. This example
# creates a URL encoded POST body:
#
# uri = URI('http://www.example.com/todo.cgi')
# req = Net::HTTP::Post.new(uri)
# req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')
#
# res = Net::HTTP.start(uri.hostname, uri.port) do |http|
# http.request(req)
# end
#
# case res
# when Net::HTTPSuccess, Net::HTTPRedirection
# # OK
# else
# res.value
# end
#
# To send multipart/form-data use Net::HTTPHeader#set_form:
#
# req = Net::HTTP::Post.new(uri)
# req.set_form([['upload', File.open('foo.bar')]], 'multipart/form-data')
#
# Other requests that can contain a body such as PUT can be created in the
# same way using the corresponding request class (Net::HTTP::Put).
#
# === Setting Headers
#
# The following example performs a conditional GET using the
# If-Modified-Since header. If the files has not been modified since the
# time in the header a Not Modified response will be returned. See RFC 2616
# section 9.3 for further details.
#
# uri = URI('http://example.com/cached_response')
# file = File.stat 'cached_response'
#
# req = Net::HTTP::Get.new(uri)
# req['If-Modified-Since'] = file.mtime.rfc2822
#
# res = Net::HTTP.start(uri.hostname, uri.port) {|http|
# http.request(req)
# }
#
# open 'cached_response', 'w' do |io|
# io.write res.body
# end if res.is_a?(Net::HTTPSuccess)
#
# === Basic Authentication
#
# Basic authentication is performed according to
# [RFC2617](http://www.ietf.org/rfc/rfc2617.txt).
#
# uri = URI('http://example.com/index.html?key=value')
#
# req = Net::HTTP::Get.new(uri)
# req.basic_auth 'user', 'pass'
#
# res = Net::HTTP.start(uri.hostname, uri.port) {|http|
# http.request(req)
# }
# puts res.body
#
# === Streaming Response Bodies
#
# By default Net::HTTP reads an entire response into memory. If you are
# handling large files or wish to implement a progress bar you can instead
# stream the body directly to an IO.
#
# uri = URI('http://example.com/large_file')
#
# Net::HTTP.start(uri.host, uri.port) do |http|
# request = Net::HTTP::Get.new uri
#
# http.request request do |response|
# open 'large_file', 'w' do |io|
# response.read_body do |chunk|
# io.write chunk
# end
# end
# end
# end
#
# === HTTPS
#
# HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=.
#
# uri = URI('https://secure.example.com/some_path?query=string')
#
# Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
# request = Net::HTTP::Get.new uri
# response = http.request request # Net::HTTPResponse object
# end
#
# Or if you simply want to make a GET request, you may pass in an URI
# object that has an HTTPS URL. Net::HTTP automatically turns on TLS
# verification if the URI object has a 'https' URI scheme.
#
# uri = URI('https://example.com/')
# Net::HTTP.get(uri) # => String
#
# In previous versions of Ruby you would need to require 'net/https' to use
# HTTPS. This is no longer true.
#
# === Proxies
#
# Net::HTTP will automatically create a proxy from the +http_proxy+
# environment variable if it is present. To disable use of +http_proxy+,
# pass +nil+ for the proxy address.
#
# You may also create a custom proxy:
#
# proxy_addr = 'your.proxy.host'
# proxy_port = 8080
#
# Net::HTTP.new('example.com', nil, proxy_addr, proxy_port).start { |http|
# # always proxy via your.proxy.addr:8080
# }
#
# See Net::HTTP.new for further details and examples such as proxies that
# require a username and password.
#
# === Compression
#
# Net::HTTP automatically adds Accept-Encoding for compression of response
# bodies and automatically decompresses gzip and deflate responses unless a
# Range header was sent.
#
# Compression can be disabled through the Accept-Encoding: identity header.
#

# Generates the Makefile for your extension, passing along any options and
# preprocessor constants that you may have generated through other methods.
#
# The +target+ name should correspond the name of the global function name
# defined within your C extension, minus the +Init_+. For example, if your
# C extension is defined as +Init_foo+, then your target would simply be
# "foo".
#
# If any "/" characters are present in the target name, only the last name
# is interpreted as the target name, and the rest are considered toplevel
# directory names, and the generated Makefile will be altered accordingly to
# follow that directory structure.
#
# For example, if you pass "test/foo" as a target name, your extension will
# be installed under the "test" directory. This means that in order to
# load the file within a Ruby program later, that directory structure will
# have to be followed, e.g. <code>require 'test/foo'</code>.
#
# The +srcprefix+ should be used when your source files are not in the same
# directory as your build script. This will not only eliminate the need for
# you to manually copy the source files into the same directory as your
# build script, but it also sets the proper +target_prefix+ in the generated
# Makefile.
#
# Setting the +target_prefix+ will, in turn, install the generated binary in
# a directory under your <code>RbConfig::CONFIG['sitearchdir']</code> that
# mimics your local filesystem when you run <code>make install</code>.
#
# For example, given the following file tree:
#
# ext/
# extconf.rb
# test/
# foo.c
#
# And given the following code:
#
# create_makefile('test/foo', 'test')
#
# That will set the +target_prefix+ in the generated Makefile to "test".
# That, in turn, will create the following file tree when installed via the
# <code>make install</code> command:
#
# /path/to/ruby/sitearchdir/test/foo.so
#
# It is recommended that you use this approach to generate your makefiles,
# instead of copying files around manually, because some third party
# libraries may depend on the +target_prefix+ being set properly.
#
# The +srcprefix+ argument can be used to override the default source
# directory, i.e. the current directory. It is included as part of the
# +VPATH+ and added to the list of +INCFLAGS+.

# = delegate -- Support for the Delegation Pattern
#
# Documentation by James Edward Gray II and Gavin Sinclair
##
# This library provides three different ways to delegate method calls to an
# object. The easiest to use is SimpleDelegator. Pass an object to the
# constructor and all methods supported by the object will be delegated. This
# object can be changed later.
#
# Going a step further, the top level DelegateClass method allows you to easily
# setup delegation through class inheritance. This is considerably more
# flexible and thus probably the most common use for this library.
#
# Finally, if you need full control over the delegation scheme, you can inherit
# from the abstract class Delegator and customize as needed. (If you find
# yourself needing this control, have a look at Forwardable which is also in
# the standard library. It may suit your needs better.)
#
# SimpleDelegator's implementation serves as a nice example of the use of
# Delegator:
#
# require 'delegate'
#
# class SimpleDelegator < Delegator
# def __getobj__
# @delegate_sd_obj # return object we are delegating to, required
# end
#
# def __setobj__(obj)
# @delegate_sd_obj = obj # change delegation object,
# # a feature we're providing
# end
# end
#
# == Notes
#
# Be advised, RDoc will not detect delegated methods.

#
# == Generating Parser Using Racc
#
# To compile Racc grammar file, simply type:
#
# $ racc parse.y
#
# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
#
# == Writing A Racc Grammar File
#
# If you want your own parser, you have to write a grammar file.
# A grammar file contains the name of your parser class, grammar for the parser,
# user code, and anything else.
# When writing a grammar file, yacc's knowledge is helpful.
# If you have not used yacc before, Racc is not too difficult.
#
# Here's an example Racc grammar file.
#
# class Calcparser
# rule
# target: exp { print val[0] }
#
# exp: exp '+' exp
# | exp '*' exp
# | '(' exp ')'
# | NUMBER
# end
#
# Racc grammar files resemble yacc files.
# But (of course), this is Ruby code.
# yacc's $$ is the 'result', $0, $1... is
# an array called 'val', and $-1, $-2... is an array called '_values'.
#
# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
# more information on grammar files.
#
# == Parser
#
# Then you must prepare the parse entry method. There are two types of
# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
#
# Racc::Parser#do_parse is simple.
#
# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
# EOF is [false, false].
# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
# If you want to change this, see the grammar reference.
#
# Racc::Parser#yyparse is little complicated, but useful.
# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
#
# For example, <code>yyparse(obj, :scan)</code> causes
# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
#
# == Debugging
#
# When debugging, "-v" or/and the "-g" option is helpful.
#
# "-v" creates verbose log file (.output).
# "-g" creates a "Verbose Parser".
# Verbose Parser prints the internal status when parsing.
# But it's _not_ automatic.
# You must use -g option and set +@yydebug+ to +true+ in order to get output.
# -g option only creates the verbose parser.
#
# === Racc reported syntax error.
#
# Isn't there too many "end"?
# grammar of racc file is changed in v0.10.
#
# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
#
# === Racc reported "XXXX conflicts".
#
# Try "racc -v xxxx.y".
# It causes producing racc's internal log file, xxxx.output.
#
# === Generated parsers does not work correctly
#
# Try "racc -g xxxx.y".
# This command let racc generate "debugging parser".
# Then set @yydebug=true in your parser.
# It produces a working log of your parser.
#
# == Re-distributing Racc runtime
#
# A parser, which is created by Racc, requires the Racc runtime module;
# racc/parser.rb.
#
# Ruby 1.8.x comes with Racc runtime module,
# you need NOT distribute Racc runtime files.
#
# If you want to include the Racc runtime module with your parser.
# This can be done by using '-E' option:
#
# $ racc -E -omyparser.rb myparser.y
#
# This command creates myparser.rb which `includes' Racc runtime.
# Only you must do is to distribute your parser file (myparser.rb).
#
# Note: parser.rb is ruby license, but your parser is not.
# Your own parser is completely yours.

#
# == Generating Parser Using Racc
#
# To compile Racc grammar file, simply type:
#
# $ racc parse.y
#
# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
#
# == Writing A Racc Grammar File
#
# If you want your own parser, you have to write a grammar file.
# A grammar file contains the name of your parser class, grammar for the parser,
# user code, and anything else.
# When writing a grammar file, yacc's knowledge is helpful.
# If you have not used yacc before, Racc is not too difficult.
#
# Here's an example Racc grammar file.
#
# class Calcparser
# rule
# target: exp { print val[0] }
#
# exp: exp '+' exp
# | exp '*' exp
# | '(' exp ')'
# | NUMBER
# end
#
# Racc grammar files resemble yacc files.
# But (of course), this is Ruby code.
# yacc's $$ is the 'result', $0, $1... is
# an array called 'val', and $-1, $-2... is an array called '_values'.
#
# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
# more information on grammar files.
#
# == Parser
#
# Then you must prepare the parse entry method. There are two types of
# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
#
# Racc::Parser#do_parse is simple.
#
# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
# EOF is [false, false].
# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
# If you want to change this, see the grammar reference.
#
# Racc::Parser#yyparse is little complicated, but useful.
# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
#
# For example, <code>yyparse(obj, :scan)</code> causes
# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
#
# == Debugging
#
# When debugging, "-v" or/and the "-g" option is helpful.
#
# "-v" creates verbose log file (.output).
# "-g" creates a "Verbose Parser".
# Verbose Parser prints the internal status when parsing.
# But it's _not_ automatic.
# You must use -g option and set +@yydebug+ to +true+ in order to get output.
# -g option only creates the verbose parser.
#
# === Racc reported syntax error.
#
# Isn't there too many "end"?
# grammar of racc file is changed in v0.10.
#
# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
#
# === Racc reported "XXXX conflicts".
#
# Try "racc -v xxxx.y".
# It causes producing racc's internal log file, xxxx.output.
#
# === Generated parsers does not work correctly
#
# Try "racc -g xxxx.y".
# This command let racc generate "debugging parser".
# Then set @yydebug=true in your parser.
# It produces a working log of your parser.
#
# == Re-distributing Racc runtime
#
# A parser, which is created by Racc, requires the Racc runtime module;
# racc/parser.rb.
#
# Ruby 1.8.x comes with Racc runtime module,
# you need NOT distribute Racc runtime files.
#
# If you want to include the Racc runtime module with your parser.
# This can be done by using '-E' option:
#
# $ racc -E -omyparser.rb myparser.y
#
# This command creates myparser.rb which `includes' Racc runtime.
# Only you must do is to distribute your parser file (myparser.rb).
#
# Note: parser.rb is ruby license, but your parser is not.
# Your own parser is completely yours.

# tsort.rb - provides a module for topological sorting and strongly connected components.
#++
#
#
# TSort implements topological sorting using Tarjan's algorithm for
# strongly connected components.
#
# TSort is designed to be able to be used with any object which can be
# interpreted as a directed graph.
#
# TSort requires two methods to interpret an object as a graph,
# tsort_each_node and tsort_each_child.
#
# * tsort_each_node is used to iterate for all nodes over a graph.
# * tsort_each_child is used to iterate for child nodes of a given node.
#
# The equality of nodes are defined by eql? and hash since
# TSort uses Hash internally.
#
# == A Simple Example
#
# The following example demonstrates how to mix the TSort module into an
# existing class (in this case, Hash). Here, we're treating each key in
# the hash as a node in the graph, and so we simply alias the required
# #tsort_each_node method to Hash's #each_key method. For each key in the
# hash, the associated value is an array of the node's child nodes. This
# choice in turn leads to our implementation of the required #tsort_each_child
# method, which fetches the array of child nodes and then iterates over that
# array using the user-supplied block.
#
# require 'tsort'
#
# class Hash
# include TSort
# alias tsort_each_node each_key
# def tsort_each_child(node, &block)
# fetch(node).each(&block)
# end
# end
#
# {1=>[2, 3], 2=>[3], 3=>[], 4=>[]}.tsort
# #=> [3, 2, 1, 4]
#
# {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components
# #=> [[4], [2, 3], [1]]
#
# == A More Realistic Example
#
# A very simple `make' like tool can be implemented as follows:
#
# require 'tsort'
#
# class Make
# def initialize
# @dep = {}
# @dep.default = []
# end
#
# def rule(outputs, inputs=[], &block)
# triple = [outputs, inputs, block]
# outputs.each {|f| @dep[f] = [triple]}
# @dep[triple] = inputs
# end
#
# def build(target)
# each_strongly_connected_component_from(target) {|ns|
# if ns.length != 1
# fs = ns.delete_if {|n| Array === n}
# raise TSort::Cyclic.new("cyclic dependencies: #{fs.join ', '}")
# end
# n = ns.first
# if Array === n
# outputs, inputs, block = n
# inputs_time = inputs.map {|f| File.mtime f}.max
# begin
# outputs_time = outputs.map {|f| File.mtime f}.min
# rescue Errno::ENOENT
# outputs_time = nil
# end
# if outputs_time == nil ||
# inputs_time != nil && outputs_time <= inputs_time
# sleep 1 if inputs_time != nil && inputs_time.to_i == Time.now.to_i
# block.call
# end
# end
# }
# end
#
# def tsort_each_child(node, &block)
# @dep[node].each(&block)
# end
# include TSort
# end
#
# def command(arg)
# print arg, "\n"
# system arg
# end
#
# m = Make.new
# m.rule(%w[t1]) { command 'date > t1' }
# m.rule(%w[t2]) { command 'date > t2' }
# m.rule(%w[t3]) { command 'date > t3' }
# m.rule(%w[t4], %w[t1 t3]) { command 'cat t1 t3 > t4' }
# m.rule(%w[t5], %w[t4 t2]) { command 'cat t4 t2 > t5' }
# m.build('t5')

# * +maxlen+ - the number of bytes to receive from the socket
# * +flags+ - zero or more of the +MSG_+ options

#
# _maxcontrollen_ is the maximum length of controls (ancillary data) to receive.
#
# _opts_ is option hash.
# Currently :scm_rights=>bool is the only option.
#
# :scm_rights option specifies that application expects SCM_RIGHTS control message.
# If the value is nil or false, application don't expects SCM_RIGHTS control message.
# In this case, recvmsg closes the passed file descriptors immediately.
# This is the default behavior.
#
# If :scm_rights value is neither nil nor false, application expects SCM_RIGHTS control message.

#
# The return value is 4-elements array.
#
# _mesg_ is a string of the received message.
#
# _sender_addrinfo_ is a sender socket address for connection-less socket.
# It is an Addrinfo object.
# For connection-oriented socket such as TCP, sender_addrinfo is platform dependent.
#
# _rflags_ is a flags on the received message which is bitwise OR of MSG_* constants such as Socket::MSG_TRUNC.
# It will be nil if the system uses 4.3BSD style old recvmsg system call.
#
# _controls_ is ancillary data which is an array of Socket::AncillaryData objects such as:

#
# _maxmesglen_ and _maxcontrollen_ can be nil.
# In that case, the buffer will be grown until the message is not truncated.

require 'delegate'
require 'tmpdir'
# A utility class for managing temporary files. When you create a Tempfile
# object, it will create a temporary file with a unique filename. A Tempfile
# objects behaves just like a File object, and you can perform all the usual
# file operations on it: reading data, writing data, changing its permissions,
# etc. So although this class does not explicitly document all instance methods
# supported by File, you can in fact call any File instance method on a
# Tempfile object.
#
# == Synopsis
#
# require 'tempfile'
#
# file = Tempfile.new('foo')
# file.path # => A unique filename in the OS's temp directory,
# # e.g.: "/tmp/foo.24722.0"
# # This filename contains 'foo' in its basename.
# file.write("hello world")
# file.rewind
# file.read # => "hello world"
# file.close
# file.unlink # deletes the temp file
#
# == Good practices
#
# === Explicit close
#
# When a Tempfile object is garbage collected, or when the Ruby interpreter
# exits, its associated temporary file is automatically deleted. This means
# that's it's unnecessary to explicitly delete a Tempfile after use, though
# it's good practice to do so: not explicitly deleting unused Tempfiles can
# potentially leave behind large amounts of tempfiles on the filesystem
# until they're garbage collected. The existence of these temp files can make
# it harder to determine a new Tempfile filename.
#
# Therefore, one should always call #unlink or close in an ensure block, like
# this:
#
# file = Tempfile.new('foo')
# begin
# # ...do something with file...
# ensure
# file.close
# file.unlink # deletes the temp file
# end
#
# Tempfile.create { ... } exists for this purpose and is more convenient to use.
# Note that Tempfile.create returns a File instance instead of a Tempfile, which
# also avoids the overhead and complications of delegation.
#
# Tempfile.open('foo') do |file|
# # ...do something with file...
# end
#
# === Unlink after creation
#
# On POSIX systems, it's possible to unlink a file right after creating it,
# and before closing it. This removes the filesystem entry without closing
# the file handle, so it ensures that only the processes that already had
# the file handle open can access the file's contents. It's strongly
# recommended that you do this if you do not want any other processes to
# be able to read from or write to the Tempfile, and you do not need to
# know the Tempfile's filename either.
#
# For example, a practical use case for unlink-after-creation would be this:
# you need a large byte buffer that's too large to comfortably fit in RAM,
# e.g. when you're writing a web server and you want to buffer the client's
# file upload data.
#
# Please refer to #unlink for more information and a code example.
#
# == Minor notes
#
# Tempfile's filename picking method is both thread-safe and inter-process-safe:
# it guarantees that no other threads or processes will pick the same filename.
#
# Tempfile itself however may not be entirely thread-safe. If you access the
# same Tempfile object from multiple threads then you should protect it with a
# mutex.
class Tempfile < DelegateClass(File)
# Creates a temporary file with permissions 0600 (= only readable and
# writable by the owner) and opens it with mode "w+".
#
# It is recommended to use Tempfile.create { ... } instead when possible,
# because that method avoids the cost of delegation and does not rely on a
# finalizer to close and unlink the file, which is unreliable.
#
# The +basename+ parameter is used to determine the name of the
# temporary file. You can either pass a String or an Array with
# 2 String elements. In the former form, the temporary file's base
# name will begin with the given string. In the latter form,
# the temporary file's base name will begin with the array's first
# element, and end with the second element. For example:
#
# file = Tempfile.new('hello')
# file.path # => something like: "/tmp/hello2843-8392-92849382--0"
#
# # Use the Array form to enforce an extension in the filename:
# file = Tempfile.new(['hello', '.jpg'])
# file.path # => something like: "/tmp/hello2843-8392-92849382--0.jpg"
#
# The temporary file will be placed in the directory as specified
# by the +tmpdir+ parameter. By default, this is +Dir.tmpdir+.
#
# file = Tempfile.new('hello', '/home/aisaka')
# file.path # => something like: "/home/aisaka/hello2843-8392-92849382--0"
#
# You can also pass an options hash. Under the hood, Tempfile creates
# the temporary file using +File.open+. These options will be passed to
# +File.open+. This is mostly useful for specifying encoding
# options, e.g.:
#
# Tempfile.new('hello', '/home/aisaka', encoding: 'ascii-8bit')
#
# # You can also omit the 'tmpdir' parameter:
# Tempfile.new('hello', encoding: 'ascii-8bit')
#
# Note: +mode+ keyword argument, as accepted by Tempfile, can only be
# numeric, combination of the modes defined in File::Constants.
#
# === Exceptions
#
# If Tempfile.new cannot find a unique filename within a limited
# number of tries, then it will raise an exception.

# file = Tempfile.new('foo')

# = ostruct.rb: OpenStruct implementation
#
# Author:: Yukihiro Matsumoto
# Documentation:: Gavin Sinclair
#
# OpenStruct allows the creation of data objects with arbitrary attributes.
# See OpenStruct for an example.
#
#
# An OpenStruct is a data structure, similar to a Hash, that allows the
# definition of arbitrary attributes with their accompanying values. This is
# accomplished by using Ruby's metaprogramming to define methods on the class
# itself.
#
# == Examples
#
# require "ostruct"
#
# person = OpenStruct.new
# person.name = "John Smith"
# person.age = 70
#
# person.name # => "John Smith"
# person.age # => 70
# person.address # => nil
#
# An OpenStruct employs a Hash internally to store the attributes and values
# and can even be initialized with one:
#
# australia = OpenStruct.new(:country => "Australia", :capital => "Canberra")
# # => #<OpenStruct country="Australia", capital="Canberra">
#
# Hash keys with spaces or characters that could normally not be used for
# method calls (e.g. <code>()[]*</code>) will not be immediately available
# on the OpenStruct object as a method for retrieval or assignment, but can
# still be reached through the Object#send method or using [].
#
# measurements = OpenStruct.new("length (in inches)" => 24)
# measurements[:"length (in inches)"] # => 24
# measurements.send("length (in inches)") # => 24
#
# message = OpenStruct.new(:queued? => true)
# message.queued? # => true
# message.send("queued?=", false)
# message.queued? # => false
#
# Removing the presence of an attribute requires the execution of the
# delete_field method as setting the property value to +nil+ will not
# remove the attribute.
#
# first_pet = OpenStruct.new(:name => "Rowdy", :owner => "John Smith")
# second_pet = OpenStruct.new(:name => "Rowdy")
#
# first_pet.owner = nil
# first_pet # => #<OpenStruct name="Rowdy", owner=nil>
# first_pet == second_pet # => false
#
# first_pet.delete_field(:owner)
# first_pet # => #<OpenStruct name="Rowdy">
# first_pet == second_pet # => true
#
# Ractor compatibility: A frozen OpenStruct with shareable values is itself shareable.
#
# == Caveats
#
# An OpenStruct utilizes Ruby's method lookup structure to find and define the
# necessary methods for properties. This is accomplished through the methods
# method_missing and define_singleton_method.
#
# This should be a consideration if there is a concern about the performance of
# the objects that are created, as there is much more overhead in the setting
# of these properties compared to using a Hash or a Struct.
# Creating an open struct from a small Hash and accessing a few of the
# entries can be 200 times slower than accessing the hash directly.
#
# This is a potential security issue; building OpenStruct from untrusted user data
# (e.g. JSON web request) may be susceptible to a "symbol denial of service" attack
# since the keys create methods and names of methods are never garbage collected.
#
# This may also be the source of incompatibilities between Ruby versions:
#
# o = OpenStruct.new
# o.then # => nil in Ruby < 2.6, enumerator for Ruby >= 2.6
#
# Builtin methods may be overwritten this way, which may be a source of bugs
# or security issues:
#
# o = OpenStruct.new
# o.methods # => [:to_h, :marshal_load, :marshal_dump, :each_pair, ...
# o.methods = [:foo, :bar]
# o.methods # => [:foo, :bar]
#
# To help remedy clashes, OpenStruct uses only protected/private methods ending with `!`
# and defines aliases for builtin public methods by adding a `!`:
#
# o = OpenStruct.new(make: 'Bentley', class: :luxury)
# o.class # => :luxury
# o.class! # => OpenStruct
#
# It is recommended (but not enforced) to not use fields ending in `!`;
# Note that a subclass' methods may not be overwritten, nor can OpenStruct's own methods
# ending with `!`.
#
# For all these reasons, consider not using OpenStruct at all.

This document is a list of user visible feature changes
since the **2.7.0** release, except for bug fixes.
Note that each entry is kept so brief that no reason behind or reference
information is supplied with. For a full list of changes with all
sufficient information, see the ChangeLog file or Redmine
(e.g. `https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER`).
## Language changes
* Keyword arguments are now separated from positional arguments.
Code that resulted in deprecation warnings in Ruby 2.7 will now
result in ArgumentError or different behavior. [[Feature #14183]]
* Procs accepting a single rest argument and keywords are no longer
subject to autosplatting. This now matches the behavior of Procs
accepting a single rest argument and no keywords.
[[Feature #16166]]
```ruby
pr = proc{|*a, **kw| [a, kw]}
pr.call([1])
# 2.7 => [[1], {}]
# 3.0 => [[[1]], {}]
pr.call([1, {a: 1}])
# 2.7 => [[1], {:a=>1}] # and deprecation warning
# 3.0 => [[[1, {:a=>1}]], {}]
```
* Arguments forwarding (`...`) now supports leading arguments.
[[Feature #16378]]
```ruby
def method_missing(meth, ...)
send(:"do_#{meth}", ...)
end
```
* Pattern matching (`case/in`) is no longer experimental. [[Feature #17260]]
* One-line pattern matching is redesigned. [EXPERIMENTAL]
* `=>` is added. It can be used like a rightward assignment.
[[Feature #17260]]
```ruby
0 => a
p a #=> 0
{b: 0, c: 1} => {b:}
p b #=> 0
```
* `in` is changed to return `true` or `false`. [[Feature #17371]]
```ruby
# version 3.0
0 in 1 #=> false
# version 2.7
0 in 1 #=> raise NoMatchingPatternError
```
* Find-pattern is added. [EXPERIMENTAL]
[[Feature #16828]]
```ruby
case ["a", 1, "b", "c", 2, "d", "e", "f", 3]
in [*pre, String => x, String => y, *post]
p pre #=> ["a", 1]
p x #=> "b"
p y #=> "c"
p post #=> [2, "d", "e", "f", 3]
end
```
* Endless method definition is added. [EXPERIMENTAL]
[[Feature #16746]]
```ruby
def square(x) = x * x
```
* Interpolated String literals are no longer frozen when
`# frozen-string-literal: true` is used. [[Feature #17104]]
* Magic comment `shareable_constant_value` added to freeze constants.
See {Magic Comments}[rdoc-ref:doc/syntax/comments.rdoc@Magic+Comments] for more details.
[[Feature #17273]]
* A {static analysis}[rdoc-label:label-Static+analysis] foundation is
introduced.
* {RBS}[rdoc-label:label-RBS] is introduced. It is a type definition
language for Ruby programs.
* {TypeProf}[rdoc-label:label-TypeProf] is experimentally bundled. It is a
type analysis tool for Ruby programs.
* Deprecation warnings are no longer shown by default (since Ruby 2.7.2).
Turn them on with `-W:deprecated` (or with `-w` to show other warnings too).
[[Feature #16345]]
* $SAFE and $KCODE are now normal global variables with no special behavior.
C-API methods related to $SAFE have been removed.
[[Feature #16131]] [[Feature #17136]]
* yield in singleton class definitions in methods is now a SyntaxError
instead of a warning. yield in a class definition outside of a method
is now a SyntaxError instead of a LocalJumpError. [[Feature #15575]]
* When a class variable is overtaken by the same definition in an
ancestor class/module, a RuntimeError is now raised (previously,
it only issued a warning in verbose mode). Additionally, accessing a
class variable from the toplevel scope is now a RuntimeError.
[[Bug #14541]]
* Assigning to a numbered parameter is now a SyntaxError instead of
a warning.
## Command line options
### `--help` option
When the environment variable `RUBY_PAGER` or `PAGER` is present and has
a non-empty value, and the standard input and output are tty, the `--help`
option shows the help message via the pager designated by the value.
[[Feature #16754]]
### `--backtrace-limit` option
The `--backtrace-limit` option limits the maximum length of a backtrace.
[[Feature #8661]]
## Core classes updates
Outstanding ones only.
* Array
* The following methods now return Array instances instead of
subclass instances when called on subclass instances:
[[Bug #6087]]
* Array#drop
* Array#drop_while
* Array#flatten
* Array#slice!
* Array#slice / Array#[]
* Array#take
* Array#take_while
* Array#uniq
* Array#*
* Can be sliced with Enumerator::ArithmeticSequence
```ruby
dirty_data = ['--', 'data1', '--', 'data2', '--', 'data3']
dirty_data[(1..).step(2)] # take each second element
# => ["data1", "data2", "data3"]
```
* Binding
* Binding#eval when called with one argument will use "(eval)"
for `__FILE__` and 1 for `__LINE__` in the evaluated code.
[[Bug #4352]] [[Bug #17419]]
* ConditionVariable
* ConditionVariable#wait may now invoke the `block`/`unblock` scheduler
hooks in a non-blocking context. [[Feature #16786]]
* Dir
* Dir.glob and Dir.[] now sort the results by default, and
accept the `sort:` keyword option. [[Feature #8709]]
* ENV
* ENV.except has been added, which returns a hash excluding the
given keys and their values. [[Feature #15822]]
* Windows: Read ENV names and values as UTF-8 encoded Strings
[[Feature #12650]]
* Encoding
* Added new encoding IBM720. [[Feature #16233]]
* Changed default for Encoding.default_external to UTF-8 on Windows
[[Feature #16604]]
* Fiber
* Fiber.new(blocking: true/false) allows you to create non-blocking
execution contexts. [[Feature #16786]]
* Fiber#blocking? tells whether the fiber is non-blocking. [[Feature #16786]]
* Fiber#backtrace and Fiber#backtrace_locations provide per-fiber backtrace.
[[Feature #16815]]
* The limitation of Fiber#transfer is relaxed. [[Bug #17221]]
* GC
* GC.auto_compact= and GC.auto_compact have been added to control
when compaction runs. Setting `auto_compact=` to true will cause
compaction to occur during major collections. At the moment,
compaction adds significant overhead to major collections, so please
test first! [[Feature #17176]]
* Hash
* Hash#transform_keys and Hash#transform_keys! now accept a hash that maps
keys to new keys. [[Feature #16274]]
* Hash#except has been added, which returns a hash excluding the
given keys and their values. [[Feature #15822]]
* IO
* IO#nonblock? now defaults to `true`. [[Feature #16786]]
* IO#wait_readable, IO#wait_writable, IO#read, IO#write and other
related methods (e.g. IO#puts, IO#gets) may invoke the scheduler hook
`#io_wait(io, events, timeout)` in a non-blocking execution context.
[[Feature #16786]]
* Kernel
* Kernel#clone when called with the `freeze: false` keyword will call
`#initialize_clone` with the `freeze: false` keyword.
[[Bug #14266]]
* Kernel#clone when called with the `freeze: true` keyword will call
`#initialize_clone` with the `freeze: true` keyword, and will
return a frozen copy even if the receiver is unfrozen.
[[Feature #16175]]
* Kernel#eval when called with two arguments will use "(eval)"
for `__FILE__` and 1 for `__LINE__` in the evaluated code.
[[Bug #4352]]
* Kernel#lambda now warns if called without a literal block.
[[Feature #15973]]
* Kernel.sleep invokes the scheduler hook `#kernel_sleep(...)` in a
non-blocking execution context. [[Feature #16786]]
* Module
* Module#include and Module#prepend now affect classes and modules
that have already included or prepended the receiver, mirroring the
behavior if the arguments were included in the receiver before
the other modules and classes included or prepended the receiver.
[[Feature #9573]]
```ruby
class C; end
module M1; end
module M2; end
C.include M1
M1.include M2
p C.ancestors #=> [C, M1, M2, Object, Kernel, BasicObject]
```
* Module#public, Module#protected, Module#private, Module#public_class_method,
Module#private_class_method, toplevel "private" and "public" methods
now accept single array argument with a list of method names. [[Feature #17314]]
* Module#attr_accessor, Module#attr_reader, Module#attr_writer and Module#attr
methods now return an array of defined method names as symbols.
[[Feature #17314]]
* Module#alias_method now returns the defined alias as a symbol.
[[Feature #17314]]
* Mutex
* `Mutex` is now acquired per-`Fiber` instead of per-`Thread`. This change
should be compatible for essentially all usages and avoids blocking when
using a scheduler. [[Feature #16792]]
* Proc
* Proc#== and Proc#eql? are now defined and will return true for
separate Proc instances if the procs were created from the same block.
[[Feature #14267]]
* Queue / SizedQueue
* Queue#pop, SizedQueue#push and related methods may now invoke the
`block`/`unblock` scheduler hooks in a non-blocking context.
[[Feature #16786]]
* Ractor
* New class added to enable parallel execution. See rdoc-ref:ractor.md for
more details.
* Random
* `Random::DEFAULT` now refers to the `Random` class instead of being a `Random` instance,
so it can work with `Ractor`.
[[Feature #17322]]
* `Random::DEFAULT` is deprecated since its value is now confusing and it is no longer global,
use `Kernel.rand`/`Random.rand` directly, or create a `Random` instance with `Random.new` instead.
[[Feature #17351]]
* String
* The following methods now return or yield String instances
instead of subclass instances when called on subclass instances:
[[Bug #10845]]
* String#*
* String#capitalize
* String#center
* String#chomp
* String#chop
* String#delete
* String#delete_prefix
* String#delete_suffix
* String#downcase
* String#dump
* String#each_char
* String#each_grapheme_cluster
* String#each_line
* String#gsub
* String#ljust
* String#lstrip
* String#partition
* String#reverse
* String#rjust
* String#rpartition
* String#rstrip
* String#scrub
* String#slice!
* String#slice / String#[]
* String#split
* String#squeeze
* String#strip
* String#sub
* String#succ / String#next
* String#swapcase
* String#tr
* String#tr_s
* String#upcase
* Symbol
* Symbol#to_proc now returns a lambda Proc. [[Feature #16260]]
* Symbol#name has been added, which returns the name of the symbol
if it is named. The returned string is frozen. [[Feature #16150]]
* Fiber
* Introduce Fiber.set_scheduler for intercepting blocking operations and
Fiber.scheduler for accessing the current scheduler. See
rdoc-ref:fiber.md for more details about what operations are supported and
how to implement the scheduler hooks. [[Feature #16786]]
* Fiber.blocking? tells whether the current execution context is
blocking. [[Feature #16786]]
* Thread#join invokes the scheduler hooks `block`/`unblock` in a
non-blocking execution context. [[Feature #16786]]
* Thread
* Thread.ignore_deadlock accessor has been added for disabling the
default deadlock detection, allowing the use of signal handlers to
break deadlock. [[Bug #13768]]
* Warning
* Warning#warn now supports a category keyword argument.
[[Feature #17122]]

## Compatibility issues
Excluding feature bug fixes.
* Regexp literals and all Range objects are frozen. [[Feature #8948]] [[Feature #16377]] [[Feature #15504]]
```ruby
/foo/.frozen? #=> true
(42...).frozen? # => true
```
* EXPERIMENTAL: Hash#each consistently yields a 2-element array. [[Bug #12706]]
* Now `{ a: 1 }.each(&->(k, v) { })` raises an ArgumentError
due to lambda's arity check.
* When writing to STDOUT redirected to a closed pipe, no broken pipe
error message will be shown now. [[Feature #14413]]
* `TRUE`/`FALSE`/`NIL` constants are no longer defined.
* Integer#zero? overrides Numeric#zero? for optimization. [[Misc #16961]]
* Enumerable#grep and Enumerable#grep_v when passed a Regexp and no block no longer modify
Regexp.last_match. [[Bug #17030]]
* Requiring 'open-uri' no longer redefines `Kernel#open`.
Call `URI.open` directly or `use URI#open` instead. [[Misc #15893]]
* SortedSet has been removed for dependency and performance reasons.
## Stdlib compatibility issues
* Default gems
* The following libraries are promoted to default gems from stdlib.
* English
* abbrev
* base64
* drb
* debug
* erb
* find
* net-ftp
* net-http
* net-imap
* net-protocol
* open-uri
* optparse
* pp
* prettyprint
* resolv-replace
* resolv
* rinda
* set
* securerandom
* shellwords
* tempfile
* tmpdir
* time
* tsort
* un
* weakref
* The following extensions are promoted to default gems from stdlib.
* digest
* io-nonblock
* io-wait
* nkf
* pathname
* syslog
* win32ole
* Bundled gems
* net-telnet and xmlrpc have been removed from the bundled gems.
If you are interested in maintaining them, please comment on
your plan to https://github.com/ruby/xmlrpc
or https://github.com/ruby/net-telnet.
* SDBM has been removed from the Ruby standard library. [[Bug #8446]]
* The issues of sdbm will be handled at https://github.com/ruby/sdbm
* WEBrick has been removed from the Ruby standard library. [[Feature #17303]]
* The issues of WEBrick will be handled at https://github.com/ruby/webrick
## C API updates
* C API functions related to $SAFE have been removed.
[[Feature #16131]]
* C API header file `ruby/ruby.h` was split. [[GH-2991]]
This should have no impact on extension libraries,
but users might experience slow compilations.
* Memory view interface [EXPERIMENTAL]
* The memory view interface is a C-API set to exchange a raw memory area,
such as a numeric array or a bitmap image, between extension libraries.
The extension libraries can share also the metadata of the memory area
that consists of the shape, the element format, and so on.
Using these kinds of metadata, the extension libraries can share even
a multidimensional array appropriately.
This feature is designed by referring to Python's buffer protocol.
[[Feature #13767]] [[Feature #14722]]
* Ractor related C APIs are introduced (experimental) in "include/ruby/ractor.h".
## Implementation improvements
* New method cache mechanism for Ractor. [[Feature #16614]]
* Inline method caches pointed from ISeq can be accessed by multiple Ractors
in parallel and synchronization is needed even for method caches. However,
such synchronization can be overhead so introducing new inline method cache
mechanisms, (1) Disposable inline method cache (2) per-Class method cache
and (3) new invalidation mechanism. (1) can avoid per-method call
synchronization because it only uses atomic operations.
See the ticket for more details.
* The number of hashes allocated when using a keyword splat in
a method call has been reduced to a maximum of 1, and passing
a keyword splat to a method that accepts specific keywords
does not allocate a hash.
* `super` is optimized when the same type of method is called in the previous call
if it's not refinements or an attr reader or writer.
### JIT
* Performance improvements of JIT-ed code
* Microarchitectural optimizations
* Native functions shared by multiple methods are deduplicated on JIT compaction.
* Decrease code size of hot paths by some optimizations and partitioning cold paths.
* Instance variables
* Eliminate some redundant checks.
* Skip checking a class and a object multiple times in a method when possible.
* Optimize accesses in some core classes like Hash and their subclasses.
* Method inlining support for some C methods
* `Kernel`: `#class`, `#frozen?`
* `Integer`: `#-@`, `#~`, `#abs`, `#bit_length`, `#even?`, `#integer?`, `#magnitude`,
`#odd?`, `#ord`, `#to_i`, `#to_int`, `#zero?`
* `Struct`: reader methods for 10th or later members
* Constant references are inlined.
* Always generate appropriate code for `==`, `nil?`, and `!` calls depending on
a receiver class.
* Reduce the number of PC accesses on branches and method returns.
* Optimize C method calls a little.
* Compilation process improvements
* It does not keep temporary files in /tmp anymore.
* Throttle GC and compaction of JIT-ed code.
* Avoid GC-ing JIT-ed code when not necessary.
* GC-ing JIT-ed code is executed in a background thread.
* Reduce the number of locks between Ruby and JIT threads.
## Static analysis
### RBS
* RBS is a new language for type definition of Ruby programs.
It allows writing types of classes and modules with advanced
types including union types, overloading, generics, and
_interface types_ for duck typing.
* Ruby ships with type definitions for core/stdlib classes.
* `rbs` gem is bundled to load and process RBS files.
### TypeProf
* TypeProf is a type analysis tool for Ruby code based on abstract interpretation.
* It reads non-annotated Ruby code, tries inferring its type signature, and prints
the analysis result in RBS format.
* Though it supports only a subset of the Ruby language yet, we will continuously
improve the coverage of language features, analysis performance, and usability.
```ruby
# test.rb
def foo(x)
if x > 10
x.to_s
else
nil
end
end
foo(42)
```
```
$ typeprof test.rb
# Classes
class Object
def foo : (Integer) -> String?
end
```
## Miscellaneous changes
* Methods using `ruby2_keywords` will no longer keep empty keyword
splats, those are now removed just as they are for methods not
using `ruby2_keywords`.
* When an exception is caught in the default handler, the error
message and backtrace are printed in order from the innermost.
[[Feature #8661]]
* Accessing an uninitialized instance variable no longer emits a
warning in verbose mode. [[Feature #17055]]

# What's Ruby
Ruby is an interpreted object-oriented programming language often
used for web development. It also offers many scripting features
to process plain text and serialized files, or manage system tasks.
It is simple, straightforward, and extensible.
## Features of Ruby
* Simple Syntax
* **Normal** Object-oriented Features (e.g. class, method calls)
* **Advanced** Object-oriented Features (e.g. mix-in, singleton-method)
* Operator Overloading
* Exception Handling
* Iterators and Closures
* Garbage Collection
* Dynamic Loading of Object Files (on some architectures)
* Highly Portable (works on many Unix-like/POSIX compatible platforms as
well as Windows, macOS, etc.) cf.
https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#label-Platform+Maintainers
## How to get Ruby
For a complete list of ways to install Ruby, including using third-party tools
like rvm, see:
https://www.ruby-lang.org/en/downloads/
### Git
The mirror of the Ruby source tree can be checked out with the following command:
$ git clone https://github.com/ruby/ruby.git
There are some other branches under development. Try the following command
to see the list of branches:
$ git ls-remote https://github.com/ruby/ruby.git
You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source)
if you are a committer.
### Subversion
Stable branches for older Ruby versions can be checked out with also the
following command:
$ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby
Try the following command to see the list of branches:
$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
## Ruby home page
https://www.ruby-lang.org/
## Mailing list
There is a mailing list to discuss Ruby. To subscribe to this list, please
send the following phrase:
subscribe
in the mail body (not subject) to the address [ruby-talk-request@ruby-lang.org].
[ruby-talk-request@ruby-lang.org]: mailto:ruby-talk-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe
## How to compile and install
1. If you want to use Microsoft Visual C++ to compile Ruby, read
[win32/README.win32](win32/README.win32) instead of this document.
2. Run `./autogen.sh` to generate configure, when you build the source checked
out from the Git repository.
3. Run `./configure`, which will generate `config.h` and `Makefile`.
Some C compiler flags may be added by default depending on your
environment. Specify `optflags=..` and `warnflags=..` as necessary to
override them.
4. Edit `include/ruby/defines.h` if you need. Usually this step will not be needed.
5. Remove comment mark(`#`) before the module names from `ext/Setup` (or add
module names if not present), if you want to link modules statically.
If you don't want to compile non static extension modules (probably on
architectures which do not allow dynamic loading), remove comment mark
from the line "`#option nodynamic`" in `ext/Setup`.
Usually this step will not be needed.
6. Run `make`.
* On Mac, set RUBY\_CODESIGN environment variable with a signing identity.
It uses the identity to sign `ruby` binary. See also codesign(1).
7. Optionally, run '`make check`' to check whether the compiled Ruby
interpreter works well. If you see the message "`check succeeded`", your
Ruby works as it should (hopefully).
8. Run '`make install`'.
This command will create the following directories and install files into
them.
* `${DESTDIR}${prefix}/bin`
* `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
* `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
* `${DESTDIR}${prefix}/lib`
* `${DESTDIR}${prefix}/lib/ruby`
* `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
* `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
* `${DESTDIR}${prefix}/lib/ruby/site_ruby`
* `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
* `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
* `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
* `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
* `${DESTDIR}${prefix}/share/man/man1`
* `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
`${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
**NOTE**: teeny of the API version may be different from one of Ruby's
program version
You may have to be a super user to install Ruby.
If you fail to compile Ruby, please send the detailed error report with the
error log and machine/OS type, to help others.
Some extension libraries may not get compiled because of lack of necessary
external libraries and/or headers, then you will need to run '`make distclean-ext`'
to remove old configuration after installing them in such case.
## Copying
See the file [COPYING](COPYING).
## Feedback
Questions about the Ruby language can be asked on the Ruby-Talk mailing list
(https://www.ruby-lang.org/en/community/mailing-lists) or on websites like
(https://stackoverflow.com).
Bugs should be reported at https://bugs.ruby-lang.org. Read [HowToReport] for more information.

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General

# BEWARE: This method is meant to serialise data from trusted user input,

# YAML event parser class. This class parses a YAML document and calls
# events on the handler that is passed to the constructor. The events can
# be used for things such as constructing a YAML AST or deserializing YAML
# documents. It can even be fed back to Psych::Emitter to emit the same
# document that was parsed.
#
# See Psych::Handler for documentation on the events that Psych::Parser emits.
#
# Here is an example that prints out ever scalar found in a YAML document:
#
# # Handler for detecting scalar values
# class ScalarHandler < Psych::Handler
# def scalar value, anchor, tag, plain, quoted, style
# puts value
# end
# end
#
# parser = Psych::Parser.new(ScalarHandler.new)
# parser.parse(yaml_document)
#
# Here is an example that feeds the parser back in to Psych::Emitter. The
# YAML document is read from STDIN and written back out to STDERR:
#
# parser = Psych::Parser.new(Psych::Emitter.new($stderr))
# parser.parse($stdin)
#
# Psych uses Psych::Parser in combination with Psych::TreeBuilder to
# construct an AST of the parsed YAML document.

# = Overview
#
# When using Psych.load to deserialize a YAML document, the document is
# translated to an intermediary AST. That intermediary AST is then
# translated in to a Ruby object graph.
#
# In the opposite direction, when using Psych.dump, the Ruby object graph is
# translated to an intermediary AST which is then converted to a YAML
# document.
#
# Psych::Nodes contains all of the classes that make up the nodes of a YAML
# AST. You can manually build an AST and use one of the visitors (see
# Psych::Visitors) to convert that AST to either a YAML document or to a
# Ruby object graph.
#
# Here is an example of building an AST that represents a list with one
# scalar:
#
# # Create our nodes
# stream = Psych::Nodes::Stream.new
# doc = Psych::Nodes::Document.new
# seq = Psych::Nodes::Sequence.new
# scalar = Psych::Nodes::Scalar.new('foo')
#
# # Build up our tree
# stream.children << doc
# doc.children << seq
# seq.children << scalar
#
# The stream is the root of the tree. We can then convert the tree to YAML:
#
# stream.to_yaml => "---\n- foo\n"
#
# Or convert it to Ruby:
#
# stream.to_ruby => [["foo"]]
#
# == YAML AST Requirements
#
# A valid YAML AST *must* have one Psych::Nodes::Stream at the root. A
# Psych::Nodes::Stream node must have 1 or more Psych::Nodes::Document nodes
# as children.
#
# Psych::Nodes::Document nodes must have one and *only* one child. That child
# may be one of:
#
# * Psych::Nodes::Sequence
# * Psych::Nodes::Mapping
# * Psych::Nodes::Scalar
#
# Psych::Nodes::Sequence and Psych::Nodes::Mapping nodes may have many
# children, but Psych::Nodes::Mapping nodes should have an even number of
# children.
#
# All of these are valid children for Psych::Nodes::Sequence and
# Psych::Nodes::Mapping nodes:
#
# * Psych::Nodes::Sequence
# * Psych::Nodes::Mapping
# * Psych::Nodes::Scalar
# * Psych::Nodes::Alias
#
# Psych::Nodes::Scalar and Psych::Nodes::Alias are both terminal nodes and
# should not have any children.

# Psych::Stream is a streaming YAML emitter. It will not buffer your YAML,
# but send it straight to an IO.
#
# Here is an example use:
#
# stream = Psych::Stream.new($stdout)
# stream.start
# stream.push({:foo => 'bar'})
# stream.finish
#
# YAML will be immediately emitted to $stdout with no buffering.
#
# Psych::Stream#start will take a block and ensure that Psych::Stream#finish
# is called, so you can do this form:
#
# stream = Psych::Stream.new($stdout)
# stream.start do |em|
# em.push(:foo => 'bar')

# Called with +encoding+ when the YAML stream starts. This method is
# called once per stream. A stream may contain multiple documents.

###
# Called when the document starts with the declared +version+,
# +tag_directives+, if the document is +implicit+.
#
# +version+ will be an array of integers indicating the YAML version being
# dealt with, +tag_directives+ is a list of tuples indicating the prefix
# and suffix of each tag, and +implicit+ is a boolean indicating whether
# the document is started implicitly.
#
# === Example
#
# Given the following YAML:
#
# %YAML 1.1
# %TAG ! tag:tenderlovemaking.com,2009:
# --- !squee
#
# The parameters for start_document must be this:
#
# version # => [1, 1]
# tag_directives # => [["!", "tag:tenderlovemaking.com,2009:"]]
# implicit # => false
def start_document version, tag_directives, implicit
end
###
# Called with the document ends. +implicit+ is a boolean value indicating
# whether or not the document has an implicit ending.
#
# === Example
#
# Given the following YAML:
#
# ---
# hello world
#
# +implicit+ will be true. Given this YAML:
#
# ---
# hello world
# ...
#
# +implicit+ will be false.
def end_document implicit
end
###
# Called when an alias is found to +anchor+. +anchor+ will be the name
# of the anchor found.
#
# === Example
#
# Here we have an example of an array that references itself in YAML:
#
# --- &ponies
# - first element
# - *ponies
#
# &ponies is the anchor, *ponies is the alias. In this case, alias is
# called with "ponies".
def alias anchor
end
###
# Called when a scalar +value+ is found. The scalar may have an
# +anchor+, a +tag+, be implicitly +plain+ or implicitly +quoted+
#
# +value+ is the string value of the scalar
# +anchor+ is an associated anchor or nil
# +tag+ is an associated tag or nil
# +plain+ is a boolean value
# +quoted+ is a boolean value
# +style+ is an integer indicating the string style
#
# See the constants in Psych::Nodes::Scalar for the possible values of
# +style+
#
# === Example
#
# Here is a YAML document that exercises most of the possible ways this
# method can be called:
#
# ---
# - !str "foo"
# - &anchor fun
# - many
# lines
# - |
# many
# newlines
#
# The above YAML document contains a list with four strings. Here are
# the parameters sent to this method in the same order:
#
# # value anchor tag plain quoted style
# ["foo", nil, "!str", false, false, 3 ]
# ["fun", "anchor", nil, true, false, 1 ]
# ["many lines", nil, nil, true, false, 1 ]
# ["many\nnewlines\n", nil, nil, false, true, 4 ]
#
def scalar value, anchor, tag, plain, quoted, style
end
###
# Called when a sequence is started.
#
# +anchor+ is the anchor associated with the sequence or nil.
# +tag+ is the tag associated with the sequence or nil.
# +implicit+ a boolean indicating whether or not the sequence was implicitly
# started.
# +style+ is an integer indicating the list style.
#
# See the constants in Psych::Nodes::Sequence for the possible values of
# +style+.
#
# === Example
#
# Here is a YAML document that exercises most of the possible ways this
# method can be called:
#
# ---
# - !!seq [
# a
# ]
# - &pewpew
# - b
#
# The above YAML document consists of three lists, an outer list that
# contains two inner lists. Here is a matrix of the parameters sent
# to represent these lists:
#
# # anchor tag implicit style
# [nil, nil, true, 1 ]
# [nil, "tag:yaml.org,2002:seq", false, 2 ]
# ["pewpew", nil, true, 1 ]
def start_sequence anchor, tag, implicit, style
end
###
# Called when a sequence ends.
def end_sequence
end
###
# Called when a map starts.
#
# +anchor+ is the anchor associated with the map or +nil+.
# +tag+ is the tag associated with the map or +nil+.
# +implicit+ is a boolean indicating whether or not the map was implicitly
# started.
# +style+ is an integer indicating the mapping style.
#
# See the constants in Psych::Nodes::Mapping for the possible values of
# +style+.
#
# === Example
#
# Here is a YAML document that exercises most of the possible ways this
# method can be called:
#
# ---
# k: !!map { hello: world }
# v: &pewpew
# hello: world
#
# The above YAML document consists of three maps, an outer map that contains
# two inner maps. Below is a matrix of the parameters sent in order to
# represent these three maps:
#
# # anchor tag implicit style
# [nil, nil, true, 1 ]
# [nil, "tag:yaml.org,2002:map", false, 2 ]
# ["pewpew", nil, true, 1 ]

## [3.0.4] - 2023-01-17
- `Rack::Request#POST` should consistently raise errors. Cache errors that occur when invoking `Rack::Request#POST` so they can be raised again later. ([#2010](https://github.com/rack/rack/pull/2010), [@ioquatix])
- Fix `Rack::Lint` error message for `HTTP_CONTENT_TYPE` and `HTTP_CONTENT_LENGTH`. ([#2007](https://github.com/rack/rack/pull/2007), [@byroot](https://github.com/byroot))
- Extend `Rack::MethodOverride` to handle `QueryParser::ParamsTooDeepError` error. ([#2006](https://github.com/rack/rack/pull/2006), [@byroot](https://github.com/byroot))
## [3.0.3] - 2022-12-27
### Fixed
- `Rack::URLMap` uses non-deprecated form of `Regexp.new`. ([#1998](https://github.com/rack/rack/pull/1998), [@weizheheng](https://github.com/weizheheng))
## [3.0.2] - 2022-12-05

## [3.0.1] - 2022-11-18
### Fixed
- `MethodOverride` does not look for an override if a request does not include form/parseable data.
- `Rack::Lint::Wrapper` correctly handles `respond_to?` with `to_ary`, `each`, `call` and `to_path`, forwarding to the body. ([#1981](https://github.com/rack/rack/pull/1981), [@ioquatix])
## [3.0.0] - 2022-09-06
- No changes
## [3.0.0.rc1] - 2022-09-04
### SPEC Changes
- Stream argument must implement `<<` https://github.com/rack/rack/pull/1959
- `close` may be called on `rack.input` https://github.com/rack/rack/pull/1956
- `rack.response_finished` may be used for executing code after the response has been finished https://github.com/rack/rack/pull/1952
## [3.0.0.beta1] - 2022-08-08
### Security
- Do not use semicolon as GET parameter separator. ([#1733](https://github.com/rack/rack/pull/1733), [@jeremyevans])
### SPEC Changes
- Response array must now be non-frozen.
- Response `status` must now be an integer greater than or equal to 100.
- Response `headers` must now be an unfrozen hash.
- Response header keys can no longer include uppercase characters.
- Response header values can be an `Array` to handle multiple values (and no longer supports `\n` encoded headers).
- Response body can now respond to `#call` (streaming body) instead of `#each` (enumerable body), for the equivalent of response hijacking in previous versions.
- Middleware must no longer call `#each` on the body, but they can call `#to_ary` on the body if it responds to `#to_ary`.
- `rack.input` is no longer required to be rewindable.
- `rack.multithread`/`rack.multiprocess`/`rack.run_once`/`rack.version` are no longer required environment keys.
- `SERVER_PROTOCOL` is now a required environment key, matching the HTTP protocol used in the request.
- `rack.hijack?` (partial hijack) and `rack.hijack` (full hijack) are now independently optional.
- `rack.hijack_io` has been removed completely.
- `rack.response_finished` is an optional environment key which contains an array of callable objects that must accept `#call(env, status, headers, error)` and are invoked after the response is finished (either successfully or unsuccessfully).
- It is okay to call `#close` on `rack.input` to indicate that you no longer need or care about the input.
- The stream argument supplied to the streaming body and hijack must support `#<<` for writing output.
### Removed
- Remove `rack.multithread`/`rack.multiprocess`/`rack.run_once`. These variables generally come too late to be useful. ([#1720](https://github.com/rack/rack/pull/1720), [@ioquatix], [@jeremyevans]))
- Remove deprecated Rack::Request::SCHEME_WHITELIST. ([@jeremyevans])
- Remove internal cookie deletion using pattern matching, there are very few practical cases where it would be useful and browsers handle it correctly without us doing anything special. ([#1844](https://github.com/rack/rack/pull/1844), [@ioquatix])
- Remove `rack.version` as it comes too late to be useful. ([#1938](https://github.com/rack/rack/pull/1938), [@ioquatix])
- Extract `rackup` command, `Rack::Server`, `Rack::Handler` and related code into a separate gem. ([#1937](https://github.com/rack/rack/pull/1937), [@ioquatix])
### Added
- `Rack::Headers` added to support lower-case header keys. ([@jeremyevans])
- `Rack::Utils#set_cookie_header` now supports `escape_key: false` to avoid key escaping. ([@jeremyevans])
- `Rack::RewindableInput` supports size. ([@ahorek](https://github.com/ahorek))
- `Rack::RewindableInput::Middleware` added for making `rack.input` rewindable. ([@jeremyevans])
- The RFC 7239 Forwarded header is now supported and considered by default when looking for information on forwarding, falling back to the X-Forwarded-* headers. `Rack::Request.forwarded_priority` accessor has been added for configuring the priority of which header to check. ([#1423](https://github.com/rack/rack/issues/1423), [@jeremyevans])
- Allow response headers to contain array of values. ([#1598](https://github.com/rack/rack/issues/1598), [@ioquatix])
- Support callable body for explicit streaming support and clarify streaming response body behaviour. ([#1745](https://github.com/rack/rack/pull/1745), [@ioquatix], [#1748](https://github.com/rack/rack/pull/1748), [@wjordan])
- Allow `Rack::Builder#run` to take a block instead of an argument. ([#1942](https://github.com/rack/rack/pull/1942), [@ioquatix])
- Add `rack.response_finished` to `Rack::Lint`. ([#1802](https://github.com/rack/rack/pull/1802), [@BlakeWilliams], [#1952](https://github.com/rack/rack/pull/1952), [@ioquatix])
- The stream argument must implement `#<<`. ([#1959](https://github.com/rack/rack/pull/1959), [@ioquatix])
### Changed
- BREAKING CHANGE: Require `status` to be an Integer. ([#1662](https://github.com/rack/rack/pull/1662), [@olleolleolle](https://github.com/olleolleolle))
- BREAKING CHANGE: Query parsing now treats parameters without `=` as having the empty string value instead of nil value, to conform to the URL spec. ([#1696](https://github.com/rack/rack/issues/1696), [@jeremyevans])
- Relax validations around `Rack::Request#host` and `Rack::Request#hostname`. ([#1606](https://github.com/rack/rack/issues/1606), [@pvande](https://github.com/pvande))
- Removed antiquated handlers: FCGI, LSWS, SCGI, Thin. ([#1658](https://github.com/rack/rack/pull/1658), [@ioquatix])
- Removed options from `Rack::Builder.parse_file` and `Rack::Builder.load_file`. ([#1663](https://github.com/rack/rack/pull/1663), [@ioquatix])
- `Rack::HTTP_VERSION` has been removed and the `HTTP_VERSION` env setting is no longer set in the CGI and Webrick handlers. ([#970](https://github.com/rack/rack/issues/970), [@jeremyevans])
- `Rack::Request#[]` and `#[]=` now warn even in non-verbose mode. ([#1277](https://github.com/rack/rack/issues/1277), [@jeremyevans])
- Decrease default allowed parameter recursion level from 100 to 32. ([#1640](https://github.com/rack/rack/issues/1640), [@jeremyevans])
- Attempting to parse a multipart response with an empty body now raises Rack::Multipart::EmptyContentError. ([#1603](https://github.com/rack/rack/issues/1603), [@jeremyevans])
- `Rack::Utils.secure_compare` uses OpenSSL's faster implementation if available. ([#1711](https://github.com/rack/rack/pull/1711), [@bdewater](https://github.com/bdewater))
- `Rack::Request#POST` now caches an empty hash if input content type is not parseable. ([#749](https://github.com/rack/rack/pull/749), [@jeremyevans])
- BREAKING CHANGE: Updated `trusted_proxy?` to match full 127.0.0.0/8 network. ([#1781](https://github.com/rack/rack/pull/1781), [@snbloch](https://github.com/snbloch))
- Explicitly deprecate `Rack::File` which was an alias for `Rack::Files`. ([#1811](https://github.com/rack/rack/pull/1720), [@ioquatix]).
- Moved `Rack::Session` into [separate gem](https://github.com/rack/rack-session). ([#1805](https://github.com/rack/rack/pull/1805), [@ioquatix])
- `rackup -D` option to daemonizes no longer changes the working directory to the root. ([#1813](https://github.com/rack/rack/pull/1813), [@jeremyevans])
- The `x-forwarded-proto` header is now considered before the `x-forwarded-scheme` header for determining the forwarded protocol. `Rack::Request.x_forwarded_proto_priority` accessor has been added for configuring the priority of which header to check. ([#1809](https://github.com/rack/rack/issues/1809), [@jeremyevans])
- `Rack::Request.forwarded_authority` (and methods that call it, such as `host`) now returns the last authority in the forwarded header, instead of the first, as earlier forwarded authorities can be forged by clients. This restores the Rack 2.1 behavior. ([#1829](https://github.com/rack/rack/issues/1809), [@jeremyevans])
- Use lower case cookie attributes when creating cookies, and fold cookie attributes to lower case when reading cookies (specifically impacting `secure` and `httponly` attributes). ([#1849](https://github.com/rack/rack/pull/1849), [@ioquatix])
- The response array must now be mutable (non-frozen) so middleware can modify it without allocating a new Array,therefore reducing object allocations. ([#1887](https://github.com/rack/rack/pull/1887), [#1927](https://github.com/rack/rack/pull/1927), [@amatsuda], [@ioquatix])
- `rack.hijack?` (partial hijack) and `rack.hijack` (full hijack) are now independently optional. `rack.hijack_io` is no longer required/specified. ([#1939](https://github.com/rack/rack/pull/1939), [@ioquatix])
- Allow calling close on `rack.input`. ([#1956](https://github.com/rack/rack/pull/1956), [@ioquatix])
### Fixed
- Make Rack::MockResponse handle non-hash headers. ([#1629](https://github.com/rack/rack/issues/1629), [@jeremyevans])
- TempfileReaper now deletes temp files if application raises an exception. ([#1679](https://github.com/rack/rack/issues/1679), [@jeremyevans])
- Handle cookies with values that end in '=' ([#1645](https://github.com/rack/rack/pull/1645), [@lukaso](https://github.com/lukaso))
- Make `Rack::NullLogger` respond to `#fatal!` [@jeremyevans])
- Fix multipart filename generation for filenames that contain spaces. Encode spaces as "%20" instead of "+" which will be decoded properly by the multipart parser. ([#1736](https://github.com/rack/rack/pull/1645), [@muirdm](https://github.com/muirdm))
- `Rack::Request#scheme` returns `ws` or `wss` when one of the `X-Forwarded-Scheme` / `X-Forwarded-Proto` headers is set to `ws` or `wss`, respectively. ([#1730](https://github.com/rack/rack/issues/1730), [@erwanst](https://github.com/erwanst))
## [2.2.4] - 2022-06-30
- Better support for lower case headers in `Rack::ETag` middleware. ([#1919](https://github.com/rack/rack/pull/1919), [@ioquatix](https://github.com/ioquatix))
- Use custom exception on params too deep error. ([#1838](https://github.com/rack/rack/pull/1838), [@simi](https://github.com/simi))
## [2.2.3.1] - 2022-05-27
- [CVE-2022-30123] Fix shell escaping issue in Common Logger
- [CVE-2022-30122] Restrict parsing of broken MIME attachments
## [2.2.3] - 2020-06-15
### Security
- [[CVE-2020-8184](https://nvd.nist.gov/vuln/detail/CVE-2020-8184)] Do not allow percent-encoded cookie name to override existing cookie names. BREAKING CHANGE: Accessing cookie names that require URL encoding with decoded name no longer works. ([@fletchto99](https://github.com/fletchto99))
## [2.2.2] - 2020-02-11
### Fixed
- Fix incorrect `Rack::Request#host` value. ([#1591](https://github.com/rack/rack/pull/1591), [@ioquatix])
- Revert `Rack::Handler::Thin` implementation. ([#1583](https://github.com/rack/rack/pull/1583), [@jeremyevans])
- Double assignment is still needed to prevent an "unused variable" warning. ([#1589](https://github.com/rack/rack/pull/1589), [@kamipo](https://github.com/kamipo))
- Fix to handle same_site option for session pool. ([#1587](https://github.com/rack/rack/pull/1587), [@kamipo](https://github.com/kamipo))
## [2.2.1] - 2020-02-09
### Fixed
- Rework `Rack::Request#ip` to handle empty `forwarded_for`. ([#1577](https://github.com/rack/rack/pull/1577), [@ioquatix])
## [2.2.0] - 2020-02-08
### SPEC Changes
- `rack.session` request environment entry must respond to `to_hash` and return unfrozen Hash. ([@jeremyevans])
- Request environment cannot be frozen. ([@jeremyevans])
- CGI values in the request environment with non-ASCII characters must use ASCII-8BIT encoding. ([@jeremyevans])
- Improve SPEC/lint relating to SERVER_NAME, SERVER_PORT and HTTP_HOST. ([#1561](https://github.com/rack/rack/pull/1561), [@ioquatix])
### Added
- `rackup` supports multiple `-r` options and will require all arguments. ([@jeremyevans])
- `Server` supports an array of paths to require for the `:require` option. ([@khotta](https://github.com/khotta))
- `Files` supports multipart range requests. ([@fatkodima](https://github.com/fatkodima))
- `Multipart::UploadedFile` supports an IO-like object instead of using the filesystem, using `:filename` and `:io` options. ([@jeremyevans])
- `Multipart::UploadedFile` supports keyword arguments `:path`, `:content_type`, and `:binary` in addition to positional arguments. ([@jeremyevans])
- `Static` supports a `:cascade` option for calling the app if there is no matching file. ([@jeremyevans])
- `Session::Abstract::SessionHash#dig`. ([@jeremyevans])

- `.ru` files supports the `frozen-string-literal` magic comment. ([@eregon](https://github.com/eregon))
- Rely on autoload to load constants instead of requiring internal files, make sure to require 'rack' and not just 'rack/...'. ([@jeremyevans])
- BREAKING CHANGE: `Etag` will continue sending ETag even if the response should not be cached. Streaming no longer works without a workaround, see [#1619](https://github.com/rack/rack/issues/1619#issuecomment-848460528). ([@henm](https://github.com/henm))
- `Request#host_with_port` no longer includes a colon for a missing or empty port. ([@AlexWayfer](https://github.com/AlexWayfer))
- All handlers uses keywords arguments instead of an options hash argument. ([@ioquatix])
- `Files` handling of range requests no longer return a body that supports `to_path`, to ensure range requests are handled correctly. ([@jeremyevans])
- `Multipart::Generator` only includes `Content-Length` for files with paths, and `Content-Disposition` `filename` if the `UploadedFile` instance has one. ([@jeremyevans])

- Remove `Rack::Files#response_body` as the implementation was broken. ([#1153](https://github.com/rack/rack/pull/1153), [@ioquatix])
- Remove `SERVER_ADDR` which was never part of the original SPEC. ([#1573](https://github.com/rack/rack/pull/1573), [@ioquatix])

- `Directory` correctly escapes paths in links. ([@yous](https://github.com/yous))
- `Request#delete_cookie` and related `Utils` methods handle `:domain` and `:path` options in same call. ([@jeremyevans])
- `Request#delete_cookie` and related `Utils` methods do an exact match on `:domain` and `:path` options. ([@jeremyevans])
- `Static` no longer adds headers when a gzipped file request has a 304 response. ([@chooh](https://github.com/chooh))
- `ContentLength` sets `Content-Length` response header even for bodies not responding to `to_ary`. ([@jeremyevans])
- Thin handler supports options passed directly to `Thin::Controllers::Controller`. ([@jeremyevans])
- WEBrick handler no longer ignores `:BindAddress` option. ([@jeremyevans])
- `ShowExceptions` handles invalid POST data. ([@jeremyevans])
- Basic authentication requires a password, even if the password is empty. ([@jeremyevans])
- `Lint` checks response is array with 3 elements, per SPEC. ([@jeremyevans])
- Support for using `:SSLEnable` option when using WEBrick handler. (Gregor Melhorn)
- Close response body after buffering it when buffering. ([@ioquatix])
- Only accept `;` as delimiter when parsing cookies. ([@mrageh](https://github.com/mrageh))
- `Utils::HeaderHash#clear` clears the name mapping as well. ([@raxoft](https://github.com/raxoft))

# History/News Archive
Items below this line are from the previously maintained HISTORY.md and NEWS.md files.
## [2.0.0.rc1] 2016-05-06
- Rack::Session::Abstract::ID is deprecated. Please change to use Rack::Session::Abstract::Persisted
## [2.0.0.alpha] 2015-12-04
- First-party "SameSite" cookies. Browsers omit SameSite cookies from third-party requests, closing the door on many CSRF attacks.
- Pass `same_site: true` (or `:strict`) to enable: response.set_cookie 'foo', value: 'bar', same_site: true or `same_site: :lax` to use Lax enforcement: response.set_cookie 'foo', value: 'bar', same_site: :lax
- Based on version 7 of the Same-site Cookies internet draft:
https://tools.ietf.org/html/draft-west-first-party-cookies-07
- Thanks to Ben Toews (@mastahyeti) and Bob Long (@bobjflong) for updating to drafts 5 and 7.
- Add `Rack::Events` middleware for adding event based middleware: middleware that does not care about the response body, but only cares about doing work at particular points in the request / response lifecycle.
- Add `Rack::Request#authority` to calculate the authority under which the response is being made (this will be handy for h2 pushes).
- Add `Rack::Response::Helpers#cache_control` and `cache_control=`. Use this for setting cache control headers on your response objects.
- Add `Rack::Response::Helpers#etag` and `etag=`. Use this for setting etag values on the response.
- Introduce `Rack::Response::Helpers#add_header` to add a value to a multi-valued response header. Implemented in terms of other `Response#*_header` methods, so it's available to any response-like class that includes the `Helpers` module.
- Add `Rack::Request#add_header` to match.
- `Rack::Session::Abstract::ID` IS DEPRECATED. Please switch to `Rack::Session::Abstract::Persisted`. `Rack::Session::Abstract::Persisted` uses a request object rather than the `env` hash.
- Pull `ENV` access inside the request object in to a module. This will help with legacy Request objects that are ENV based but don't want to inherit from Rack::Request
- Move most methods on the `Rack::Request` to a module `Rack::Request::Helpers` and use public API to get values from the request object. This enables users to mix `Rack::Request::Helpers` in to their own objects so they can implement `(get|set|fetch|each)_header` as they see fit (for example a proxy object).
- Files and directories with + in the name are served correctly. Rather than unescaping paths like a form, we unescape with a URI parser using `Rack::Utils.unescape_path`. Fixes #265
- Tempfiles are automatically closed in the case that there were too
many posted.
- Added methods for manipulating response headers that don't assume
they're stored as a Hash. Response-like classes may include the
Rack::Response::Helpers module if they define these methods:
- Rack::Response#has_header?
- Rack::Response#get_header
- Rack::Response#set_header
- Rack::Response#delete_header
- Introduce Util.get_byte_ranges that will parse the value of the HTTP_RANGE string passed to it without depending on the `env` hash. `byte_ranges` is deprecated in favor of this method.
- Change Session internals to use Request objects for looking up session information. This allows us to only allocate one request object when dealing with session objects (rather than doing it every time we need to manipulate cookies, etc).
- Add `Rack::Request#initialize_copy` so that the env is duped when the request gets duped.
- Added methods for manipulating request specific data. This includes
data set as CGI parameters, and just any arbitrary data the user wants
to associate with a particular request. New methods:
- Rack::Request#has_header?
- Rack::Request#get_header
- Rack::Request#fetch_header
- Rack::Request#each_header
- Rack::Request#set_header
- Rack::Request#delete_header
- lib/rack/utils.rb: add a method for constructing "delete" cookie
headers. This allows us to construct cookie headers without depending
on the side effects of mutating a hash.
- Prevent extremely deep parameters from being parsed. CVE-2015-3225

> **_NOTE:_** Rack v3.0.0 was recently released. Please check the [Upgrade

Rack provides a minimal, modular, and adaptable interface for developing web
applications in Ruby. By wrapping HTTP requests and responses in the simplest
way possible, it unifies and distills the bridge between web servers, web
frameworks, and web application into a single method call.
The exact details of this are described in the [Rack Specification], which all
Rack applications should conform to.
## Installation
Add the rack gem to your application bundle, or follow the instructions provided
by a [supported web framework](#supported-web-frameworks):
```bash
# Install it generally:
$ gem install rack --pre
# or, add it to your current application gemfile:
$ bundle add rack --version 3.0.0
```
If you need features from `Rack::Session` or `bin/rackup` please add those gems separately.
```bash
$ gem install rack-session rackup
```
## Usage
Create a file called `config.ru` with the following contents:
```ruby
run do |env|
[200, {}, ["Hello World"]]
end
```
Run this using the rackup gem or another [supported web
server](#supported-web-servers).
```bash
$ gem install rackup
$ rackup
$ curl http://localhost:9292
Hello World
```
## Supported web servers
Rack is supported by a wide range of servers, including:
* [Agoo](https://github.com/ohler55/agoo)
* [Falcon](https://github.com/socketry/falcon) **(Rack 3 Compatible)**
* [Iodine](https://github.com/boazsegev/iodine)
* [NGINX Unit](https://unit.nginx.org/)
* [Phusion Passenger](https://www.phusionpassenger.com/) (which is mod_rack for
Apache and for nginx)
* [Puma](https://puma.io/)
* [Thin](https://github.com/macournoyer/thin)
* [Unicorn](https://yhbt.net/unicorn/)
* [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/)
* [Lamby](https://lamby.custominktech.com) (for AWS Lambda)
You will need to consult the server documentation to find out what features and
limitations they may have. In general, any valid Rack app will run the same on
all these servers, without changing anything.
### Rackup
Rack provides a separate gem, [rackup](https://github.com/rack/rackup) which is
a generic interface for running a Rack application on supported servers, which
include `WEBRick`, `Puma`, `Falcon` and others.
## Supported web frameworks
These frameworks and many others support the [Rack Specification]:
* [Camping](https://github.com/camping/camping)
* [Hanami](https://hanamirb.org/)
* [Padrino](https://padrinorb.com/)
* [Roda](https://github.com/jeremyevans/roda) **(Rack 3 Compatible)**
* [Ruby on Rails](https://rubyonrails.org/)
* [Sinatra](https://sinatrarb.com/)
* [Utopia](https://github.com/socketry/utopia) **(Rack 3 Compatible)**
* [WABuR](https://github.com/ohler55/wabur)
### Older (possibly unsupported) web frameworks
* [Ramaze](http://ramaze.net/)
* [Rum](https://github.com/leahneukirchen/rum)
## Available middleware shipped with Rack
Between the server and the framework, Rack can be customized to your
applications needs using middleware. Rack itself ships with the following
middleware:
* `Rack::CommonLogger` for creating Apache-style logfiles.
* `Rack::ConditionalGet` for returning [Not
Modified](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/304)
responses when the response has not changed.
* `Rack::Config` for modifying the environment before processing the request.
* `Rack::ContentLength` for setting a `content-length` header based on body
size.
* `Rack::ContentType` for setting a default `content-type` header for responses.
* `Rack::Deflater` for compressing responses with gzip.
* `Rack::ETag` for setting `etag` header on bodies that can be buffered.
* `Rack::Events` for providing easy hooks when a request is received and when
the response is sent.
* `Rack::Files` for serving static files.
* `Rack::Head` for returning an empty body for HEAD requests.
* `Rack::Lint` for checking conformance to the [Rack Specification].
* `Rack::Lock` for serializing requests using a mutex.
* `Rack::Logger` for setting a logger to handle logging errors.
* `Rack::MethodOverride` for modifying the request method based on a submitted
parameter.
* `Rack::Recursive` for including data from other paths in the application, and
for performing internal redirects.
* `Rack::Reloader` for reloading files if they have been modified.
* `Rack::Runtime` for including a response header with the time taken to process
the request.
* `Rack::Sendfile` for working with web servers that can use optimized file
serving for file system paths.
* `Rack::ShowException` for catching unhandled exceptions and presenting them in
a nice and helpful way with clickable backtrace.
* `Rack::ShowStatus` for using nice error pages for empty client error
responses.
* `Rack::Static` for more configurable serving of static files.
* `Rack::TempfileReaper` for removing temporary files creating during a request.
All these components use the same interface, which is described in detail in the
[Rack Specification]. These optional components can be used in any way you wish.
### Convenience interfaces
If you want to develop outside of existing frameworks, implement your own ones,
or develop middleware, Rack provides many helpers to create Rack applications
quickly and without doing the same web stuff all over:
* `Rack::Request` which also provides query string parsing and multipart
handling.
* `Rack::Response` for convenient generation of HTTP replies and cookie
handling.
* `Rack::MockRequest` and `Rack::MockResponse` for efficient and quick testing
of Rack application without real HTTP round-trips.
* `Rack::Cascade` for trying additional Rack applications if an application
returns a not found or method not supported response.
* `Rack::Directory` for serving files under a given directory, with directory
indexes.
* `Rack::MediaType` for parsing content-type headers.
* `Rack::Mime` for determining content-type based on file extension.
* `Rack::RewindableInput` for making any IO object rewindable, using a temporary
file buffer.
* `Rack::URLMap` to route to multiple applications inside the same process.
## Configuration
Rack exposes several configuration parameters to control various features of the
implementation.
### `param_depth_limit`
```ruby
Rack::Utils.param_depth_limit = 32 # default
```
The maximum amount of nesting allowed in parameters. For example, if set to 3,
this query string would be allowed:
```
?a[b][c]=d
```
but this query string would not be allowed:
```
?a[b][c][d]=e
```
Limiting the depth prevents a possible stack overflow when parsing parameters.
### `multipart_file_limit`
```ruby
Rack::Utils.multipart_file_limit = 128 # default
```
The maximum number of parts with a filename a request can contain. Accepting
too many parts can lead to the server running out of file handles.
The default is 128, which means that a single request can't upload more than 128
files at once. Set to 0 for no limit.
Can also be set via the `RACK_MULTIPART_FILE_LIMIT` environment variable.
(This is also aliased as `multipart_part_limit` and `RACK_MULTIPART_PART_LIMIT` for compatibility)
### `multipart_total_part_limit`
The maximum total number of parts a request can contain of any type, including
both file and non-file form fields.
The default is 4096, which means that a single request can't contain more than
4096 parts.
Set to 0 for no limit.
Can also be set via the `RACK_MULTIPART_TOTAL_PART_LIMIT` environment variable.

= Rack applications
A Rack application is a Ruby object (not a class) that
responds to +call+.
It takes exactly one argument, the *environment*
and returns a non-frozen Array of exactly three values:
The *status*,
the *headers*,
and the *body*.
== The Environment
The environment must be an unfrozen instance of Hash that includes
CGI-like headers. The Rack application is free to modify the
environment.
The environment is required to include these variables
(adopted from {PEP 333}[https://peps.python.org/pep-0333/]), except when they'd be empty, but see
below.
<tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
"GET" or "POST". This cannot ever
be an empty string, and so is
always required.
<tt>SCRIPT_NAME</tt>:: The initial portion of the request
URL's "path" that corresponds to the
application object, so that the
application knows its virtual
"location". This may be an empty
string, if the application corresponds
to the "root" of the server.
<tt>PATH_INFO</tt>:: The remainder of the request URL's
"path", designating the virtual
"location" of the request's target
within the application. This may be an
empty string, if the request URL targets
the application root and does not have a
trailing slash. This value may be
percent-encoded when originating from
a URL.
<tt>QUERY_STRING</tt>:: The portion of the request URL that
follows the <tt>?</tt>, if any. May be
empty, but is always required!
<tt>SERVER_NAME</tt>:: When combined with <tt>SCRIPT_NAME</tt> and
<tt>PATH_INFO</tt>, these variables can be
used to complete the URL. Note, however,
that <tt>HTTP_HOST</tt>, if present,
should be used in preference to
<tt>SERVER_NAME</tt> for reconstructing
the request URL.
<tt>SERVER_NAME</tt> can never be an empty
string, and so is always required.
<tt>SERVER_PORT</tt>:: An optional +Integer+ which is the port the
server is running on. Should be specified if
the server is running on a non-standard port.
<tt>SERVER_PROTOCOL</tt>:: A string representing the HTTP version used
for the request.
<tt>HTTP_</tt> Variables:: Variables corresponding to the
client-supplied HTTP request
headers (i.e., variables whose
names begin with <tt>HTTP_</tt>). The
presence or absence of these
variables should correspond with
the presence or absence of the
appropriate HTTP header in the
request. See
{RFC3875 section 4.1.18}[https://tools.ietf.org/html/rfc3875#section-4.1.18]
for specific behavior.
In addition to this, the Rack environment must include these
Rack-specific variables:
<tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the
request URL.
<tt>rack.input</tt>:: See below, the input stream.
<tt>rack.errors</tt>:: See below, the error stream.
<tt>rack.hijack?</tt>:: See below, if present and true, indicates
that the server supports partial hijacking.
<tt>rack.hijack</tt>:: See below, if present, an object responding
to +call+ that is used to perform a full
hijack.
Additional environment specifications have approved to
standardized middleware APIs. None of these are required to
be implemented by the server.
<tt>rack.session</tt>:: A hash-like interface for storing
request session data.
The store must implement:
store(key, value) (aliased as []=);
fetch(key, default = nil) (aliased as []);
delete(key);
clear;
to_hash (returning unfrozen Hash instance);
<tt>rack.logger</tt>:: A common object interface for logging messages.
The object must implement:
info(message, &block)
debug(message, &block)
warn(message, &block)
error(message, &block)
fatal(message, &block)
<tt>rack.multipart.buffer_size</tt>:: An Integer hint to the multipart parser as to what chunk size to use for reads and writes.
<tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind. This factory will be used to instantiate the tempfile for each multipart form file upload field, rather than the default class of Tempfile.
The server or the application can store their own data in the
environment, too. The keys must contain at least one dot,
and should be prefixed uniquely. The prefix <tt>rack.</tt>
is reserved for use with the Rack core distribution and other
accepted specifications and must not be used otherwise.
The <tt>SERVER_PORT</tt> must be an Integer if set.
The <tt>SERVER_NAME</tt> must be a valid authority as defined by RFC7540.
The <tt>HTTP_HOST</tt> must be a valid authority as defined by RFC7540.
The <tt>SERVER_PROTOCOL</tt> must match the regexp <tt>HTTP/\d(\.\d)?</tt>.
If the <tt>HTTP_VERSION</tt> is present, it must equal the <tt>SERVER_PROTOCOL</tt>.
The environment must not contain the keys
<tt>HTTP_CONTENT_TYPE</tt> or <tt>HTTP_CONTENT_LENGTH</tt>
(use the versions without <tt>HTTP_</tt>).
The CGI keys (named without a period) must have String values.
If the string values for CGI keys contain non-ASCII characters,
they should use ASCII-8BIT encoding.
There are the following restrictions:
* <tt>rack.url_scheme</tt> must either be +http+ or +https+.
* There must be a valid input stream in <tt>rack.input</tt>.
* There must be a valid error stream in <tt>rack.errors</tt>.
* There may be a valid hijack callback in <tt>rack.hijack</tt>
* The <tt>REQUEST_METHOD</tt> must be a valid token.
* The <tt>SCRIPT_NAME</tt>, if non-empty, must start with <tt>/</tt>
* The <tt>PATH_INFO</tt>, if non-empty, must start with <tt>/</tt>
* The <tt>CONTENT_LENGTH</tt>, if given, must consist of digits only.
* One of <tt>SCRIPT_NAME</tt> or <tt>PATH_INFO</tt> must be
set. <tt>PATH_INFO</tt> should be <tt>/</tt> if
<tt>SCRIPT_NAME</tt> is empty.
<tt>SCRIPT_NAME</tt> never should be <tt>/</tt>, but instead be empty.
<tt>rack.response_finished</tt>:: An array of callables run by the server after the response has been
processed. This would typically be invoked after sending the response to the client, but it could also be
invoked if an error occurs while generating the response or sending the response; in that case, the error
argument will be a subclass of +Exception+.
The callables are invoked with +env, status, headers, error+ arguments and should not raise any
exceptions. They should be invoked in reverse order of registration.
=== The Input Stream
The input stream is an IO-like object which contains the raw HTTP
POST data.
When applicable, its external encoding must be "ASCII-8BIT" and it
must be opened in binary mode, for Ruby 1.9 compatibility.
The input stream must respond to +gets+, +each+, and +read+.
* +gets+ must be called without arguments and return a string,
or +nil+ on EOF.
* +read+ behaves like IO#read.
Its signature is <tt>read([length, [buffer]])</tt>.
If given, +length+ must be a non-negative Integer (>= 0) or +nil+,
and +buffer+ must be a String and may not be nil.
If +length+ is given and not nil, then this method reads at most
+length+ bytes from the input stream.
If +length+ is not given or nil, then this method reads
all data until EOF.
When EOF is reached, this method returns nil if +length+ is given
and not nil, or "" if +length+ is not given or is nil.
If +buffer+ is given, then the read data will be placed
into +buffer+ instead of a newly created String object.
* +each+ must be called without arguments and only yield Strings.
* +close+ can be called on the input stream to indicate that the
any remaining input is not needed.
=== The Error Stream
The error stream must respond to +puts+, +write+ and +flush+.
* +puts+ must be called with a single argument that responds to +to_s+.
* +write+ must be called with a single argument that is a String.
* +flush+ must be called without arguments and must be called
in order to make the error appear for sure.
* +close+ must never be called on the error stream.
=== Hijacking
The hijacking interfaces provides a means for an application to take
control of the HTTP connection. There are two distinct hijack
interfaces: full hijacking where the application takes over the raw
connection, and partial hijacking where the application takes over
just the response body stream. In both cases, the application is
responsible for closing the hijacked stream.
Full hijacking only works with HTTP/1. Partial hijacking is functionally
equivalent to streaming bodies, and is still optionally supported for
backwards compatibility with older Rack versions.
==== Full Hijack
Full hijack is used to completely take over an HTTP/1 connection. It
occurs before any headers are written and causes the request to
ignores any response generated by the application.
It is intended to be used when applications need access to raw HTTP/1
connection.
If +rack.hijack+ is present in +env+, it must respond to +call+
and return an +IO+ instance which can be used to read and write
to the underlying connection using HTTP/1 semantics and
formatting.
==== Partial Hijack
Partial hijack is used for bi-directional streaming of the request and
response body. It occurs after the status and headers are written by
the server and causes the server to ignore the Body of the response.
It is intended to be used when applications need bi-directional
streaming.
If +rack.hijack?+ is present in +env+ and truthy,
an application may set the special response header +rack.hijack+
to an object that responds to +call+,
accepting a +stream+ argument.
After the response status and headers have been sent, this hijack
callback will be invoked with a +stream+ argument which follows the
same interface as outlined in "Streaming Body". Servers must
ignore the +body+ part of the response tuple when the
+rack.hijack+ response header is present. Using an empty +Array+
instance is recommended.
The special response header +rack.hijack+ must only be set
if the request +env+ has a truthy +rack.hijack?+.
== The Response
=== The Status
This is an HTTP status. It must be an Integer greater than or equal to
100.
=== The Headers
The headers must be a unfrozen Hash.
The header keys must be Strings.
Special headers starting "rack." are for communicating with the
server, and must not be sent back to the client.
The header must not contain a +Status+ key.
Header keys must conform to RFC7230 token specification, i.e. cannot
contain non-printable ASCII, DQUOTE or "(),/:;<=>?@[\]{}".
Header keys must not contain uppercase ASCII characters (A-Z).
Header values must be either a String instance,
or an Array of String instances,
such that each String instance must not contain characters below 037.
=== The content-type
There must not be a <tt>content-type</tt> header key when the +Status+ is 1xx,
204, or 304.
=== The content-length
There must not be a <tt>content-length</tt> header key when the
+Status+ is 1xx, 204, or 304.
=== The Body
The Body is typically an +Array+ of +String+ instances, an enumerable
that yields +String+ instances, a +Proc+ instance, or a File-like
object.
The Body must respond to +each+ or +call+. It may optionally respond
to +to_path+ or +to_ary+. A Body that responds to +each+ is considered
to be an Enumerable Body. A Body that responds to +call+ is considered
to be a Streaming Body.
A Body that responds to both +each+ and +call+ must be treated as an
Enumerable Body, not a Streaming Body. If it responds to +each+, you
must call +each+ and not +call+. If the Body doesn't respond to
+each+, then you can assume it responds to +call+.
The Body must either be consumed or returned. The Body is consumed by
optionally calling either +each+ or +call+.
Then, if the Body responds to +close+, it must be called to release
any resources associated with the generation of the body.
In other words, +close+ must always be called at least once; typically
after the web server has sent the response to the client, but also in
cases where the Rack application makes internal/virtual requests and
discards the response.
After calling +close+, the Body is considered closed and should not
be consumed again.
If the original Body is replaced by a new Body, the new Body must
also consume the original Body by calling +close+ if possible.
If the Body responds to +to_path+, it must return a +String+
path for the local file system whose contents are identical
to that produced by calling +each+; this may be used by the
server as an alternative, possibly more efficient way to
transport the response. The +to_path+ method does not consume
the body.
==== Enumerable Body
The Enumerable Body must respond to +each+.
It must only be called once.
It must not be called after being closed.
and must only yield String values.
The Body itself should not be an instance of String, as this will
break in Ruby 1.9.
Middleware must not call +each+ directly on the Body.
Instead, middleware can return a new Body that calls +each+ on the
original Body, yielding at least once per iteration.
If the Body responds to +to_ary+, it must return an +Array+ whose
contents are identical to that produced by calling +each+.
Middleware may call +to_ary+ directly on the Body and return a new
Body in its place. In other words, middleware can only process the
Body directly if it responds to +to_ary+. If the Body responds to both
+to_ary+ and +close+, its implementation of +to_ary+ must call
+close+.
==== Streaming Body
The Streaming Body must respond to +call+.
It must only be called once.
It must not be called after being closed.
It takes a +stream+ argument.
The +stream+ argument must implement:
<tt>read, write, <<, flush, close, close_read, close_write, closed?</tt>
The semantics of these IO methods must be a best effort match to
those of a normal Ruby IO or Socket object, using standard arguments
and raising standard exceptions. Servers are encouraged to simply
pass on real IO objects, although it is recognized that this approach
is not directly compatible with HTTP/2.

# However, be aware that calling `body.each` inside the block will break cases where `body.each` is not idempotent,
# such as when it is an +IO+ instance.
# :include :: a list of content types that should be compressed. By default, all content types are compressed.
# :sync :: determines if the stream is going to be flushed after every chunk. Flushing after every chunk reduces
# latency for time-sensitive streaming applications, but hurts compression and throughput.

### This middleware provides hooks to certain places in the request /
# response lifecycle. This is so that middleware that don't need to filter
# the response data can safely leave it alone and not have to send messages
# down the traditional "rack stack".
#
# The events are:
#
# * on_start(request, response)
#
# This event is sent at the start of the request, before the next
# middleware in the chain is called. This method is called with a request
# object, and a response object. Right now, the response object is always
# nil, but in the future it may actually be a real response object.
#
# * on_commit(request, response)
#
# The response has been committed. The application has returned, but the
# response has not been sent to the webserver yet. This method is always
# called with a request object and the response object. The response
# object is constructed from the rack triple that the application returned.
# Changes may still be made to the response object at this point.
#
# * on_send(request, response)
#
# The webserver has started iterating over the response body and presumably
# has started sending data over the wire. This method is always called with
# a request object and the response object. The response object is
# constructed from the rack triple that the application returned. Changes
# SHOULD NOT be made to the response object as the webserver has already
# started sending data. Any mutations will likely result in an exception.
#
# * on_finish(request, response)
#
# The webserver has closed the response, and all data has been written to
# the response socket. The request and response object should both be
# read-only at this point. The body MAY NOT be available on the response
# object as it may have been flushed to the socket.
#
# * on_error(request, response, error)
#
# An exception has occurred in the application or an `on_commit` event.
# This method will get the request, the response (if available) and the
# exception that was raised.
#
# ## Order
#
# `on_start` is called on the handlers in the order that they were passed to
# the constructor. `on_commit`, on_send`, `on_finish`, and `on_error` are
# called in the reverse order. `on_finish` handlers are called inside an
# `ensure` block, so they are guaranteed to be called even if something
# raises an exception. If something raises an exception in a `on_finish`
# method, then nothing is guaranteed.

# The Rack::Static middleware intercepts requests for static files
# (javascript files, images, stylesheets, etc) based on the url prefixes or
# route mappings passed in the options, and serves them using a Rack::Files
# object. This allows a Rack stack to serve both static and dynamic content.
#
# Examples:
#
# Serve all requests beginning with /media from the "media" folder located
# in the current directory (ie media/*):
#
# use Rack::Static, :urls => ["/media"]
#
# Same as previous, but instead of returning 404 for missing files under
# /media, call the next middleware:
#
# use Rack::Static, :urls => ["/media"], :cascade => true
#
# Serve all requests beginning with /css or /images from the folder "public"
# in the current directory (ie public/css/* and public/images/*):
#
# use Rack::Static, :urls => ["/css", "/images"], :root => "public"
#
# Serve all requests to / with "index.html" from the folder "public" in the
# current directory (ie public/index.html):
#
# use Rack::Static, :urls => {"/" => 'index.html'}, :root => 'public'
#
# Serve all requests normally from the folder "public" in the current
# directory but uses index.html as default route for "/"
#
# use Rack::Static, :urls => [""], :root => 'public', :index =>
# 'index.html'
#
# Set custom HTTP Headers for based on rules:
#
# use Rack::Static, :root => 'public',
# :header_rules => [
# [rule, {header_field => content, header_field => content}],
# [rule, {header_field => content}]
# ]
#
# Rules for selecting files:
#
# 1) All files
# Provide the :all symbol
# :all => Matches every file
#
# 2) Folders
# Provide the folder path as a string
# '/folder' or '/folder/subfolder' => Matches files in a certain folder
#
# 3) File Extensions
# Provide the file extensions as an array
# ['css', 'js'] or %w(css js) => Matches files ending in .css or .js
#
# 4) Regular Expressions / Regexp
# Provide a regular expression
# %r{\.(?:css|js)\z} => Matches files ending in .css or .js
# /\.(?:eot|ttf|otf|woff2|woff|svg)\z/ => Matches files ending in
# the most common web font formats (.eot, .ttf, .otf, .woff2, .woff, .svg)
# Note: This Regexp is available as a shortcut, using the :fonts rule
#
# 5) Font Shortcut
# Provide the :fonts symbol
# :fonts => Uses the Regexp rule stated right above to match all common web font endings
#
# Rule Ordering:
# Rules are applied in the order that they are provided.
# List rather general rules above special ones.
#
# Complete example use case including HTTP header rules:
#
# use Rack::Static, :root => 'public',
# :header_rules => [
# # Cache all static files in public caches (e.g. Rack::Cache)
# # as well as in the browser
# [:all, {'cache-control' => 'public, max-age=31536000'}],
#
# # Provide web fonts with cross-origin access-control-headers
# # Firefox requires this when serving assets using a Content Delivery Network

module Rack
# = Sendfile
#
# The Sendfile middleware intercepts responses whose body is being
# served from a file and replaces it with a server specific x-sendfile
# header. The web server is then responsible for writing the file contents
# to the client. This can dramatically reduce the amount of work required
# by the Ruby backend and takes advantage of the web server's optimized file
# delivery code.
#
# In order to take advantage of this middleware, the response body must
# respond to +to_path+ and the request must include an x-sendfile-type
# header. Rack::Files and other components implement +to_path+ so there's
# rarely anything you need to do in your application. The x-sendfile-type
# header is typically set in your web servers configuration. The following
# sections attempt to document
#
# === Nginx
#
# Nginx supports the x-accel-redirect header. This is similar to x-sendfile
# but requires parts of the filesystem to be mapped into a private URL
# hierarchy.
#
# The following example shows the Nginx configuration required to create
# a private "/files/" area, enable x-accel-redirect, and pass the special
# x-sendfile-type and x-accel-mapping headers to the backend:
#
# location ~ /files/(.*) {
# internal;
# alias /var/www/$1;
# }
#
# location / {
# proxy_redirect off;
#
# proxy_set_header Host $host;
# proxy_set_header X-Real-IP $remote_addr;
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#
# proxy_set_header x-sendfile-type x-accel-redirect;
# proxy_set_header x-accel-mapping /var/www/=/files/;
#
# proxy_pass http://127.0.0.1:8080/;
# }
#
# Note that the x-sendfile-type header must be set exactly as shown above.
# The x-accel-mapping header should specify the location on the file system,
# followed by an equals sign (=), followed name of the private URL pattern
# that it maps to. The middleware performs a simple substitution on the
# resulting path.
#
# See Also: https://www.nginx.com/resources/wiki/start/topics/examples/xsendfile
#
# === lighttpd
#
# Lighttpd has supported some variation of the x-sendfile header for some
# time, although only recent version support x-sendfile in a reverse proxy
# configuration.
#
# $HTTP["host"] == "example.com" {
# proxy-core.protocol = "http"
# proxy-core.balancer = "round-robin"
# proxy-core.backends = (
# "127.0.0.1:8000",
# "127.0.0.1:8001",
# ...
# )
#
# proxy-core.allow-x-sendfile = "enable"
# proxy-core.rewrite-request = (
# "x-sendfile-type" => (".*" => "x-sendfile")
# )
# }
#
# See Also: http://redmine.lighttpd.net/wiki/lighttpd/Docs:ModProxyCore
#
# === Apache
#
# x-sendfile is supported under Apache 2.x using a separate module:
#
# https://tn123.org/mod_xsendfile/
#
# Once the module is compiled and installed, you can enable it using
# XSendFile config directive:
#
# RequestHeader Set x-sendfile-type x-sendfile
# ProxyPassReverse / http://localhost:8001/
# XSendFile on
#
# === Mapping parameter
#
# The third parameter allows for an overriding extension of the
# x-accel-mapping header. Mappings should be provided in tuples of internal to
# external. The internal values may contain regular expression syntax, they
# will be matched with case indifference.

##
## The environment is required to include these variables
## (adopted from {PEP 333}[https://peps.python.org/pep-0333/]), except when they'd be empty, but see
## below.
## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
## "GET" or "POST". This cannot ever
## be an empty string, and so is
## always required.
## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
## URL's "path" that corresponds to the
## application object, so that the
## application knows its virtual
## "location". This may be an empty
## string, if the application corresponds
## to the "root" of the server.
## <tt>PATH_INFO</tt>:: The remainder of the request URL's
## "path", designating the virtual
## "location" of the request's target
## within the application. This may be an
## empty string, if the request URL targets
## the application root and does not have a
## trailing slash. This value may be
## percent-encoded when originating from
## a URL.
## <tt>QUERY_STRING</tt>:: The portion of the request URL that
## follows the <tt>?</tt>, if any. May be
## empty, but is always required!
## <tt>SERVER_NAME</tt>:: When combined with <tt>SCRIPT_NAME</tt> and
## <tt>PATH_INFO</tt>, these variables can be
## used to complete the URL. Note, however,
## that <tt>HTTP_HOST</tt>, if present,
## should be used in preference to
## <tt>SERVER_NAME</tt> for reconstructing
## the request URL.
## <tt>SERVER_NAME</tt> can never be an empty
## string, and so is always required.
## <tt>SERVER_PORT</tt>:: An optional +Integer+ which is the port the
## server is running on. Should be specified if
## the server is running on a non-standard port.
## <tt>SERVER_PROTOCOL</tt>:: A string representing the HTTP version used
## for the request.
## <tt>HTTP_</tt> Variables:: Variables corresponding to the
## client-supplied HTTP request
## headers (i.e., variables whose
## names begin with <tt>HTTP_</tt>). The
## presence or absence of these
## variables should correspond with
## the presence or absence of the
## appropriate HTTP header in the
## request. See
## {RFC3875 section 4.1.18}[https://tools.ietf.org/html/rfc3875#section-4.1.18]
## for specific behavior.
## In addition to this, the Rack environment must include these
## Rack-specific variables:
## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the
## request URL.
## <tt>rack.input</tt>:: See below, the input stream.
## <tt>rack.errors</tt>:: See below, the error stream.
## <tt>rack.hijack?</tt>:: See below, if present and true, indicates
## that the server supports partial hijacking.
## <tt>rack.hijack</tt>:: See below, if present, an object responding
## to +call+ that is used to perform a full
## hijack.
## Additional environment specifications have approved to
## standardized middleware APIs. None of these are required to
## be implemented by the server.
## <tt>rack.session</tt>:: A hash-like interface for storing
## request session data.
## The store must implement:
if session = env[RACK_SESSION]
## store(key, value) (aliased as []=);
unless session.respond_to?(:store) && session.respond_to?(:[]=)
raise LintError, "session #{session.inspect} must respond to store and []="
end
## fetch(key, default = nil) (aliased as []);
unless session.respond_to?(:fetch) && session.respond_to?(:[])
raise LintError, "session #{session.inspect} must respond to fetch and []"
end

raise LintError, "session #{session.inspect} must respond to delete"
end
## clear;
unless session.respond_to?(:clear)
raise LintError, "session #{session.inspect} must respond to clear"
end
## to_hash (returning unfrozen Hash instance);
unless session.respond_to?(:to_hash) && session.to_hash.kind_of?(Hash) && !session.to_hash.frozen?
raise LintError, "session #{session.inspect} must respond to to_hash and return unfrozen Hash instance"
end
end
## <tt>rack.logger</tt>:: A common object interface for logging messages.
## The object must implement:
if logger = env[RACK_LOGGER]
## info(message, &block)
unless logger.respond_to?(:info)
raise LintError, "logger #{logger.inspect} must respond to info"
end
## debug(message, &block)

end
## fatal(message, &block)
unless logger.respond_to?(:fatal)
raise LintError, "logger #{logger.inspect} must respond to fatal"
end
end

if bufsize = env[RACK_MULTIPART_BUFFER_SIZE]
unless bufsize.is_a?(Integer) && bufsize > 0
raise LintError, "rack.multipart.buffer_size must be an Integer > 0 if specified"
end
end
## <tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind. This factory will be used to instantiate the tempfile for each multipart form file upload field, rather than the default class of Tempfile.

##
## === Hijacking
##
## The hijacking interfaces provides a means for an application to take
## control of the HTTP connection. There are two distinct hijack
## interfaces: full hijacking where the application takes over the raw
## connection, and partial hijacking where the application takes over
## just the response body stream. In both cases, the application is
## responsible for closing the hijacked stream.
##
## Full hijacking only works with HTTP/1. Partial hijacking is functionally
## equivalent to streaming bodies, and is still optionally supported for
## backwards compatibility with older Rack versions.
##
## ==== Full Hijack
##
## Full hijack is used to completely take over an HTTP/1 connection. It
## occurs before any headers are written and causes the request to
## ignores any response generated by the application.
##
## It is intended to be used when applications need access to raw HTTP/1
## connection.
##
def check_hijack(env)
## If +rack.hijack+ is present in +env+, it must respond to +call+
if original_hijack = env[RACK_HIJACK]
raise LintError, "rack.hijack must respond to call" unless original_hijack.respond_to?(:call)
env[RACK_HIJACK] = proc do
io = original_hijack.call
## and return an +IO+ instance which can be used to read and write
## to the underlying connection using HTTP/1 semantics and
## formatting.
raise LintError, "rack.hijack must return an IO instance" unless io.is_a?(IO)
io
end
end
end
##
## ==== Partial Hijack
##
## Partial hijack is used for bi-directional streaming of the request and
## response body. It occurs after the status and headers are written by
## the server and causes the server to ignore the Body of the response.
##
## It is intended to be used when applications need bi-directional
## streaming.
##
def check_hijack_response(headers, env)
## If +rack.hijack?+ is present in +env+ and truthy,
if env[RACK_IS_HIJACK]
## an application may set the special response header +rack.hijack+
if original_hijack = headers[RACK_HIJACK]
## to an object that responds to +call+,
unless original_hijack.respond_to?(:call)
raise LintError, 'rack.hijack header must respond to #call'
end
## accepting a +stream+ argument.
return proc do |io|
original_hijack.call StreamWrapper.new(io)
end
end
##
## After the response status and headers have been sent, this hijack
## callback will be invoked with a +stream+ argument which follows the
## same interface as outlined in "Streaming Body". Servers must
## ignore the +body+ part of the response tuple when the
## +rack.hijack+ response header is present. Using an empty +Array+
## instance is recommended.
else
##
## The special response header +rack.hijack+ must only be set
## if the request +env+ has a truthy +rack.hijack?+.
if headers.key?(RACK_HIJACK)
raise LintError, 'rack.hijack header must not be present if server does not support hijacking'
end
end
nil
end
## == The Response
##
## === The Status
##
def check_status(status)
## This is an HTTP status. It must be an Integer greater than or equal to
## 100.
unless status.is_a?(Integer) && status >= 100
raise LintError, "Status must be an Integer >=100"
end
end
##
## === The Headers
##
def check_headers(headers)
## The headers must be a unfrozen Hash.
unless headers.kind_of?(Hash)
raise LintError, "headers object should be a hash, but isn't (got #{headers.class} as headers)"
end
if headers.frozen?
raise LintError, "headers object should not be frozen, but is"
end
headers.each do |key, value|
## The header keys must be Strings.
unless key.kind_of? String
raise LintError, "header key must be a string, was #{key.class}"
end
## Special headers starting "rack." are for communicating with the
## server, and must not be sent back to the client.
next if key.start_with?("rack.")
## The header must not contain a +Status+ key.
raise LintError, "header must not contain status" if key == "status"
## Header keys must conform to RFC7230 token specification, i.e. cannot
## contain non-printable ASCII, DQUOTE or "(),/:;<=>?@[\]{}".
raise LintError, "invalid header name: #{key}" if key =~ /[\(\),\/:;<=>\?@\[\\\]{}[:cntrl:]]/
## Header keys must not contain uppercase ASCII characters (A-Z).
raise LintError, "uppercase character in header name: #{key}" if key =~ /[A-Z]/
## Header values must be either a String instance,
if value.kind_of?(String)
check_header_value(key, value)
elsif value.kind_of?(Array)
## or an Array of String instances,
value.each{|value| check_header_value(key, value)}
else
raise LintError, "a header value must be a String or Array of Strings, but the value of '#{key}' is a #{value.class}"
end
end
end

## such that each String instance must not contain characters below 037.
if value =~ /[\000-\037]/
raise LintError, "invalid header value #{key}: #{value.inspect}"
end
end
##
## === The content-type
##
def check_content_type(status, headers)
headers.each { |key, value|
## There must not be a <tt>content-type</tt> header key when the +Status+ is 1xx,
## 204, or 304.
if key == "content-type"
if Rack::Utils::STATUS_WITH_NO_ENTITY_BODY.key? status.to_i
raise LintError, "content-type header found in #{status} response, not allowed"
end
return
end
}
end
##
## === The content-length
##
def check_content_length(status, headers)
headers.each { |key, value|
if key == 'content-length'
## There must not be a <tt>content-length</tt> header key when the
## +Status+ is 1xx, 204, or 304.
if Rack::Utils::STATUS_WITH_NO_ENTITY_BODY.key? status.to_i
raise LintError, "content-length header found in #{status} response, not allowed"
end
@content_length = value
end
}
end
def verify_content_length(size)
if @head_request
unless size == 0
raise LintError, "Response body was given for HEAD request, but should be empty"
end
elsif @content_length
unless @content_length == size.to_s
raise LintError, "content-length header was #{@content_length}, but should be #{size}"
end
end
end
##
## === The Body
##
## The Body is typically an +Array+ of +String+ instances, an enumerable
## that yields +String+ instances, a +Proc+ instance, or a File-like
## object.
##
## The Body must respond to +each+ or +call+. It may optionally respond
## to +to_path+ or +to_ary+. A Body that responds to +each+ is considered
## to be an Enumerable Body. A Body that responds to +call+ is considered
## to be a Streaming Body.
##
## A Body that responds to both +each+ and +call+ must be treated as an
## Enumerable Body, not a Streaming Body. If it responds to +each+, you
## must call +each+ and not +call+. If the Body doesn't respond to
## +each+, then you can assume it responds to +call+.
##
## The Body must either be consumed or returned. The Body is consumed by
## optionally calling either +each+ or +call+.
## Then, if the Body responds to +close+, it must be called to release
## any resources associated with the generation of the body.
## In other words, +close+ must always be called at least once; typically
## after the web server has sent the response to the client, but also in
## cases where the Rack application makes internal/virtual requests and
## discards the response.
##
def close
##
## After calling +close+, the Body is considered closed and should not
## be consumed again.
@closed = true
## If the original Body is replaced by a new Body, the new Body must
## also consume the original Body by calling +close+ if possible.
@body.close if @body.respond_to?(:close)
index = @lint.index(self)
unless @env['rack.lint'][0..index].all? {|lint| lint.instance_variable_get(:@closed)}
raise LintError, "Body has not been closed"
end
end
def verify_to_path
##
## If the Body responds to +to_path+, it must return a +String+
## path for the local file system whose contents are identical
## to that produced by calling +each+; this may be used by the
## server as an alternative, possibly more efficient way to
## transport the response. The +to_path+ method does not consume
## the body.
if @body.respond_to?(:to_path)
unless ::File.exist? @body.to_path
raise LintError, "The file identified by body.to_path does not exist"
end
end
end
##
## ==== Enumerable Body
##
def each
## The Enumerable Body must respond to +each+.
raise LintError, "Enumerable Body must respond to each" unless @body.respond_to?(:each)
## It must only be called once.
raise LintError, "Response body must only be invoked once (#{@invoked})" unless @invoked.nil?
## It must not be called after being closed.
raise LintError, "Response body is already closed" if @closed
@invoked = :each
@body.each do |chunk|
## and must only yield String values.
unless chunk.kind_of? String
raise LintError, "Body yielded non-string value #{chunk.inspect}"
end
##
## The Body itself should not be an instance of String, as this will
## break in Ruby 1.9.
##
## Middleware must not call +each+ directly on the Body.
## Instead, middleware can return a new Body that calls +each+ on the
## original Body, yielding at least once per iteration.
if @lint[0] == self
@env['rack.lint.body_iteration'] += 1
else
if (@env['rack.lint.body_iteration'] -= 1) > 0
raise LintError, "New body must yield at least once per iteration of old body"
end
end
@size += chunk.bytesize
yield chunk
end
verify_content_length(@size)
verify_to_path
end

def to_path
@body.to_path
end
def respond_to?(name, *)
if BODY_METHODS.key?(name)
@body.respond_to?(name)
else
super
end
end
##
## If the Body responds to +to_ary+, it must return an +Array+ whose
## contents are identical to that produced by calling +each+.
## Middleware may call +to_ary+ directly on the Body and return a new
## Body in its place. In other words, middleware can only process the
## Body directly if it responds to +to_ary+. If the Body responds to both
## +to_ary+ and +close+, its implementation of +to_ary+ must call
## +close+.
def to_ary
@body.to_ary.tap do |content|
unless content == @body.enum_for.to_a
raise LintError, "#to_ary not identical to contents produced by calling #each"
end
end
ensure
close
end
##
## ==== Streaming Body
##
def call(stream)
## The Streaming Body must respond to +call+.
raise LintError, "Streaming Body must respond to call" unless @body.respond_to?(:call)
## It must only be called once.
raise LintError, "Response body must only be invoked once (#{@invoked})" unless @invoked.nil?
## It must not be called after being closed.
raise LintError, "Response body is already closed" if @closed
@invoked = :call
## It takes a +stream+ argument.
##
## The +stream+ argument must implement:
## <tt>read, write, <<, flush, close, close_read, close_write, closed?</tt>
##
@body.call(StreamWrapper.new(stream))
end
class StreamWrapper
extend Forwardable
## The semantics of these IO methods must be a best effort match to
## those of a normal Ruby IO or Socket object, using standard arguments
## and raising standard exceptions. Servers are encouraged to simply
## pass on real IO objects, although it is recognized that this approach
## is not directly compatible with HTTP/2.
REQUIRED_METHODS = [
:read, :write, :<<, :flush, :close,
:close_read, :close_write, :closed?
]
def_delegators :@stream, *REQUIRED_METHODS
def initialize(stream)

lsapi - LSAPI extension for Ruby
================================
INSTALL
-------
$ ruby setup.rb config
$ ruby setup.rb setup
# ruby setup.rb install
USAGE
-----
General CGI scripts
^^^^^^^^^^^^^^^^^^^
The most efficient way to use LSAPI interface is to modify your CGI scripts.
You need to add the following code to your CGI scripts:
require 'lsapi'
while LSAPI.accept != nil
<your CGI script>
...
end
There is no need to change the way that how CGI environment variables
are being accessed in your scripts.
You can find some examples under examples/ folder.
Ruby Script Runner
^^^^^^^^^^^^^^^^^^
If you don't want to change your existing Ruby CGI code, you can use our
Ruby script runner under scripts/ folder. You need to configure
lsruby_runner.rb as a LSAPI application, then add a script handler
for "rb" suffix.
Rails dispatcher
^^^^^^^^^^^^^^^^
With Ruby LSAPI, we proudly provide a optimum platform for Rails application
deployment. Ruby LSAPI has the following advantages over other solutions.
* Easy configuration, deploy a Rails application only take a few clicks
with our Rails easy configuration
* Fast startup, the expensive Rails framework initialization only takes
place once when multiple processes need to be started
* Resource efficience, ruby processes can be started on demand, idle
process will be stop.
To use LSAPI with Ruby on Rails, please check out our toturial
http://www.litespeedtech.com/support/wiki/doku.php
There are a few environment variables that can be tweaked to tune ruby
LSAPI process.
* LSAPI_CHILDREN (default: 0)
LSAPI_CHILDREN controls the maximum number of children processes can be
started by the first ruby process started by web server. When set to <=1,
the first ruby process will handle request by itself, without starting any
child process. When LSAPI_CHILDREN is >1, the LSAPI application is stared in
"Self Managed Mode", which will start children processes based on demand.
With Rails easy configuration, LSAPI_CHILDREN is set to the value of
"Max Connections" by web server, no need to set it explicitly.
Usually, there is no need to set value of LSAPI_CHILDREN over 100 in most
server environment.
* LSAPI_AVOID_FORK (default: 0)
LSAPI_AVOID_FORK specifies the policy of the internal process manager in
"Self Managed Mode". When set to 0, the internal process manager will stop
and start children process on demand to save system resource. This is
preferred in a shared hosting environment. When set to 1, the internal
process manager will try to avoid freqently stopping and starting children
process. This might be preferred in a dedicate hosting environment.
* LSAPI_EXTRA_CHILDREN (default: 1/3 of LSAPI_CHILDREN or 0)
LSAPI_EXTRA_CHILDREN controls the maximum number of extra children processes
can be started when some or all existing children processes are in
malfunctioning state. Total number of children processes will be reduced to
LSAPI_CHILDREN level as soon as service is back to normal.
When LSAPI_AVOID_FORK is set to 0, the default value is 1/3 of
LSAPI_CHIDLREN, When LSAPI_AVOID_FORK is set to 1, the default value is 0.
* LSAPI_MAX_REQS (default value: 10000)
LSAPI_MAX_REQS specifies the maximum number of requests each child
process will handle before it exits automatically. This parameter can
help reducing memory usage when there are memory leaks in the application.
* LSAPI_MAX_IDLE (default value: 300 seconds)
In Self Managed Mode, LSAPI_MAX_IDLE controls how long a idle child
process will wait for a new request before exit. This option help
releasing system resources taken by idle processes.
* LSAPI_MAX_IDLE_CHILDREN
(default value: 1/3 of LSAPI_CHILDREN or LSAPI_CHILDREN)
In Self Managed Mode, LSAI_MAX_IDLE_CHILDREN controls how many idle
children processes are allowed. Excessive idle children processes
will be killed by the parent process.
When LSAPI_AVOID_FORK is set to 0, the default value is 1/3 of
LSAPI_CHIDLREN, When LSAPI_AVOID_FORK is set to 1, the default value
is LSAPI_CHILDREN.
* LSAPI_MAX_PROCESS_TIME (default value: 300 seconds)
In Self Managed Mode, LSAPI_MAX_PROCESS_TIME controls the maximum
processing time allowed when processing a request. If a child process
can not finish processing of a request in the given time period, it
will be killed by the parent process. This option can help getting rid
of dead or runaway child process.
* LSAPI_PGRP_MAX_IDLE (default value: FOREVER )
In Self Managed Mode, LSAPI_PGRP_MAX_IDLE controls how long the parent
process will wait before exiting when there is no child process.
This option help releasing system resources taken by an idle parent
process.
* LSAPI_PPID_NO_CHECK
By default a LSAPI application check the existence of its parent process
and exits automatically if the parent process died. This is to reduce
orphan process when web server is restarted. However, it is desireable
to disable this feature, such as when a LSAPI process was started
manually from command line. LSAPI_PPID_NO_CHECK should be set when
you want to disable the checking of existence of parent process.

Rake is invoked from the command line using:
% rake [options ...] [VAR=VALUE ...] [targets ...]
Options are:
[<tt><em>name</em>=<em>value</em></tt>]
Set the environment variable <em>name</em> to <em>value</em>
during the execution of the <b>rake</b> command. You can access
the value by using ENV['<em>name</em>'].
[<tt>--all</tt> (-A)]
Used in combination with the -T and -D options, will force
those options to show all the tasks, even the ones without comments.
[<tt>--backtrace</tt>{=_output_} (-n)]
Enable a full backtrace (i.e. like --trace, but without the task
tracing details). The _output_ parameter is optional, but if
specified it controls where the backtrace output is sent. If
_output_ is <tt>stdout</tt>, then backtrace output is directed to
standard output. If _output_ is <tt>stderr</tt>, or if it is
missing, then the backtrace output is sent to standard error.
[<tt>--comments</tt>]
Used in combination with the -W options to force the output to
contain commented options only. This is the reverse of
<tt>--all</tt>.
[<tt>--describe</tt> _pattern_ (-D)]
Describe the tasks (matching optional PATTERN), then exit.
[<tt>--dry-run</tt> (-n)]
Do a dry run. Print the tasks invoked and executed, but do not
actually execute any of the actions.
[<tt>--execute</tt> _code_ (-e)]
Execute some Ruby code and exit.
[<tt>--execute-print</tt> _code_ (-p)]
Execute some Ruby code, print the result, and exit.
[<tt>--execute-continue</tt> _code_ (-E)]
Execute some Ruby code, then continue with normal task processing.
[<tt>--help</tt> (-H)]
Display some help text and exit.
[<tt>--jobs</tt> _number_ (-j)]
Specifies the maximum number of concurrent threads allowed. Rake
will allocate threads as needed up to this maximum number.
If omitted, Rake will attempt to estimate the number of CPUs on
the system and add 4 to that number.
The concurrent threads are used to execute the <tt>multitask</tt>
prerequisites. Also see the <tt>-m</tt> option which turns all
tasks into multitasks.
Sample values:
(no -j) : Allow up to (# of CPUs + 4) number of threads
--jobs : Allow unlimited number of threads
--jobs=1 : Allow only one thread (the main thread)
--jobs=16 : Allow up to 16 concurrent threads
[<tt>--job-stats</tt> _level_]
Display job statistics at the completion of the run. By default,
this will display the requested number of active threads (from the
-j options) and the maximum number of threads in play at any given
time.
If the optional _level_ is <tt>history</tt>, then a complete trace
of task history will be displayed on standard output.
[<tt>--libdir</tt> _directory_ (-I)]
Add _directory_ to the list of directories searched for require.
[<tt>--multitask</tt> (-m)]
Treat all tasks as multitasks. ('make/drake' semantics)
[<tt>--nosearch</tt> (-N)]
Do not search for a Rakefile in parent directories.
[<tt>--prereqs</tt> (-P)]
Display a list of all tasks and their immediate prerequisites.
[<tt>--quiet</tt> (-q)]
Do not echo commands from FileUtils.
[<tt>--rakefile</tt> _filename_ (-f)]
Use _filename_ as the name of the rakefile. The default rakefile
names are +rakefile+ and +Rakefile+ (with +rakefile+ taking
precedence). If the rakefile is not found in the current
directory, +rake+ will search parent directories for a match. The
directory where the Rakefile is found will become the current
directory for the actions executed in the Rakefile.
[<tt>--rakelibdir</tt> _rakelibdir_ (-R)]
Auto-import any .rake files in RAKELIBDIR. (default is 'rakelib')
[<tt>--require</tt> _name_ (-r)]
Require _name_ before executing the Rakefile.
[<tt>--rules</tt>]
Trace the rules resolution.
[<tt>--silent (-s)</tt>]
Like --quiet, but also suppresses the 'in directory' announcement.
[<tt>--suppress-backtrace _pattern_ </tt>]
Line matching the regular expression _pattern_ will be removed
from the backtrace output. Note that the --backtrace option is the
full backtrace without these lines suppressed.
[<tt>--system</tt> (-g)]
Use the system wide (global) rakefiles. The project Rakefile is
ignored. By default, the system wide rakefiles are used only if no
project Rakefile is found. On Unix-like system, the system wide
rake files are located in $HOME/.rake. On a windows system they
are stored in $APPDATA/Rake.
[<tt>--no-system</tt> (-G)]
Use the project level Rakefile, ignoring the system-wide (global)
rakefiles.
[<tt>--tasks</tt> <em>pattern</em> (-T)]
Display a list of the major tasks and their comments. Comments
are defined using the "desc" command. If a pattern is given, then
only tasks matching the pattern are displayed.
[<tt>--trace</tt>{=_output_} (-t)]
Turn on invoke/execute tracing. Also enable full backtrace on
errors. The _output_ parameter is optional, but if specified it
controls where the trace output is sent. If _output_ is
<tt>stdout</tt>, then trace output is directed to standard output.
If _output_ is <tt>stderr</tt>, or if it is missing, then trace
output is sent to standard error.
[<tt>--verbose</tt> (-v)]
Echo the Sys commands to standard output.
[<tt>--version</tt> (-V)]
Display the program version and exit.
[<tt>--where</tt> <em>pattern</em> (-W)]
Display tasks that match <em>pattern</em> and the file and line
number where the task is defined. By default this option will
display all tasks, not just the tasks that have descriptions.
[<tt>--no-deprecation-warnings</tt> (-X)]
Do not display the deprecation warnings.
In addition, any command line option of the form
<em>VAR</em>=<em>VALUE</em> will be added to the environment hash
<tt>ENV</tt> and may be tested in the Rakefile.

First of all, there is no special format for a Rakefile. A Rakefile
contains executable Ruby code. Anything legal in a ruby script is
allowed in a Rakefile.
Now that we understand there is no special syntax in a Rakefile, there
are some conventions that are used in a Rakefile that are a little
unusual in a typical Ruby program. Since a Rakefile is tailored to
specifying tasks and actions, the idioms used in a Rakefile are
designed to support that.
So, what goes into a Rakefile?
== Tasks
Tasks are the main unit of work in a Rakefile. Tasks have a name
(usually given as a symbol or a string), a list of prerequisites (more
symbols or strings) and a list of actions (given as a block).
=== Simple Tasks
A task is declared by using the +task+ method. +task+ takes a single
parameter that is the name of the task.
task :name
=== Tasks with Prerequisites
Any prerequisites are given as a list (enclosed in square brackets)
following the name and an arrow (=>).
task name: [:prereq1, :prereq2]
*NOTE:* Although this syntax looks a little funky, it is legal
Ruby. We are constructing a hash where the key is :name and the value
for that key is the list of prerequisites. It is equivalent to the
following ...
hash = Hash.new
hash[:name] = [:prereq1, :prereq2]
task(hash)
You can also use strings for task names and prerequisites, rake doesn't care.
This is the same task definition:
task 'name' => %w[prereq1 prereq2]
As is this:
task name: %w[prereq1 prereq2]
We'll prefer this style for regular tasks with prerequisites throughout the
rest of the document. Using an array of strings for the prerequisites means
you will need to make fewer changes if you need to move tasks into namespaces
or perform other refactorings.
=== Tasks with Actions
Actions are defined by passing a block to the +task+ method. Any Ruby
code can be placed in the block. The block may reference the task
object via the block parameter.
task name: [:prereq1, :prereq2] do |t|
# actions (may reference t)
end
=== Multiple Definitions
A task may be specified more than once. Each specification adds its
prerequisites and actions to the existing definition. This allows one
part of a rakefile to specify the actions and a different rakefile
(perhaps separately generated) to specify the dependencies.
For example, the following is equivalent to the single task
specification given above.
task :name
task name: :prereq1
task name: %w[prereq2]
task :name do |t|
# actions
end
== File Tasks
Some tasks are designed to create a file from one or more other files.
Tasks that generate these files may be skipped if the file already
exists. File tasks are used to specify file creation tasks.
File tasks are declared using the +file+ method (instead of the +task+
method). In addition, file tasks are usually named with a string
rather than a symbol.
The following file task creates a executable program (named +prog+)
given two object files named +a.o+ and +b.o+. The tasks
for creating +a.o+ and +b.o+ are not shown.
file "prog" => ["a.o", "b.o"] do |t|
sh "cc -o #{t.name} #{t.prerequisites.join(' ')}"
end
== Directory Tasks
It is common to need to create directories upon demand. The
+directory+ convenience method is a short-hand for creating a FileTask
that creates the directory. For example, the following declaration
...
directory "testdata/examples/doc"
is equivalent to ...
file "testdata" do |t| mkdir t.name end
file "testdata/examples" => ["testdata"] do |t| mkdir t.name end
file "testdata/examples/doc" => ["testdata/examples"] do |t| mkdir t.name end
The +directory+ method does not accept prerequisites or actions, but
both prerequisites and actions can be added later. For example ...
directory "testdata"
file "testdata" => ["otherdata"]
file "testdata" do
cp Dir["standard_data/*.data"], "testdata"
end
== Tasks with Parallel Prerequisites
Rake allows parallel execution of prerequisites using the following syntax:
multitask copy_files: %w[copy_src copy_doc copy_bin] do
puts "All Copies Complete"
end
In this example, +copy_files+ is a normal rake task. Its actions are
executed whenever all of its prerequisites are done. The big
difference is that the prerequisites (+copy_src+, +copy_bin+ and
+copy_doc+) are executed in parallel. Each of the prerequisites are
run in their own Ruby thread, possibly allowing faster overall runtime.
=== Secondary Prerequisites
If any of the primary prerequisites of a multitask have common secondary
prerequisites, all of the primary/parallel prerequisites will wait
until the common prerequisites have been run.
For example, if the <tt>copy_<em>xxx</em></tt> tasks have the
following prerequisites:
task copy_src: :prep_for_copy
task copy_bin: :prep_for_copy
task copy_doc: :prep_for_copy
Then the +prep_for_copy+ task is run before starting all the copies in
parallel. Once +prep_for_copy+ is complete, +copy_src+, +copy_bin+,
and +copy_doc+ are all run in parallel. Note that +prep_for_copy+ is
run only once, even though it is referenced in multiple threads.
=== Thread Safety
The Rake internal data structures are thread-safe with respect
to the multitask parallel execution, so there is no need for the user
to do extra synchronization for Rake's benefit. However, if there are
user data structures shared between the parallel prerequisites, the
user must do whatever is necessary to prevent race conditions.
== Tasks with Arguments
Prior to version 0.8.0, rake was only able to handle command line
arguments of the form NAME=VALUE that were passed into Rake via the
ENV hash. Many folks had asked for some kind of simple command line
arguments, perhaps using "--" to separate regular task names from
argument values on the command line. The problem is that there was no
easy way to associate positional arguments on the command line with
different tasks. Suppose both tasks :a and :b expect a command line
argument: does the first value go with :a? What if :b is run first?
Should it then get the first command line argument.
Rake 0.8.0 solves this problem by explicitly passing values directly
to the tasks that need them. For example, if I had a release task
that required a version number, I could say:
rake release[0.8.2]
And the string "0.8.2" will be passed to the :release task. Multiple
arguments can be passed by separating them with a comma, for example:
rake name[john,doe]
Just a few words of caution. The rake task name and its arguments
need to be a single command line argument to rake. This generally
means no spaces. If spaces are needed, then the entire name +
argument string should be quoted. Something like this:
rake "name[billy bob, smith]"
(Quoting rules vary between operating systems and shells, so make sure
you consult the proper docs for your OS/shell).
=== Tasks that Expect Parameters
Parameters are only given to tasks that are setup to expect them. In
order to handle named parameters, the task declaration syntax for
tasks has been extended slightly.
For example, a task that needs a first name and last name might be
declared as:
task :name, [:first_name, :last_name]
The first argument is still the name of the task (:name in this case).
The next two arguments are the names of the parameters expected by
:name in an array (:first_name and :last_name in the example).
To access the values of the parameters, the block defining the task
behaviour can now accept a second parameter:
task :name, [:first_name, :last_name] do |t, args|
puts "First name is #{args.first_name}"
puts "Last name is #{args.last_name}"
end
The first argument of the block "t" is always bound to the current
task object. The second argument "args" is an open-struct like object
that allows access to the task arguments. Extra command line
arguments to a task are ignored.
If you wish to specify default values for the arguments, you can use
the with_defaults method in the task body. Here is the above example
where we specify default values for the first and last names:
task :name, [:first_name, :last_name] do |t, args|
args.with_defaults(:first_name => "John", :last_name => "Dough")
puts "First name is #{args.first_name}"
puts "Last name is #{args.last_name}"
end
=== Tasks that Expect Parameters and Have Prerequisites
Tasks that use parameters have a slightly different format for
prerequisites. Use the arrow notation to indicate the prerequisites
for tasks with arguments. For example:
task :name, [:first_name, :last_name] => [:pre_name] do |t, args|
args.with_defaults(:first_name => "John", :last_name => "Dough")
puts "First name is #{args.first_name}"
puts "Last name is #{args.last_name}"
end
=== Tasks that take Variable-length Parameters
Tasks that need to handle a list of values as a parameter can use the
extras method of the args variable. This allows for tasks that can
loop over a variable number of values, and its compatible with named
parameters as well:
task :email, [:message] do |t, args|
mail = Mail.new(args.message)
recipients = args.extras
recipients.each do |target|
mail.send_to(target)
end
end
There is also the convenience method to_a that returns all parameters
in the sequential order they were given, including those associated
with named parameters.
=== Deprecated Task Parameters Format
There is an older format for declaring task parameters that omitted
the task argument array and used the :needs keyword to introduce the
dependencies. That format is still supported for compatibility, but
is not recommended for use. The older format may be dropped in future
versions of rake.
== Accessing Task Programmatically
Sometimes it is useful to manipulate tasks programmatically in a
Rakefile. To find a task object use Rake::Task.[].
=== Programmatic Task Example
For example, the following Rakefile defines two tasks. The :doit task
simply prints a simple "DONE" message. The :dont class will lookup
the doit class and remove (clear) all of its prerequisites and
actions.
task :doit do
puts "DONE"
end
task :dont do
Rake::Task[:doit].clear
end
Running this example:
$ rake doit
(in /Users/jim/working/git/rake/x)
DONE
$ rake dont doit
(in /Users/jim/working/git/rake/x)
$
The ability to programmatically manipulate tasks gives rake very
powerful meta-programming capabilities w.r.t. task execution, but
should be used with caution.
== Rules
When a file is named as a prerequisite, but does not have a file task
defined for it, Rake will attempt to synthesize a task by looking at a
list of rules supplied in the Rakefile.
Suppose we were trying to invoke task "mycode.o", but no task is
defined for it. But the rakefile has a rule that look like this ...
rule '.o' => ['.c'] do |t|
sh "cc #{t.source} -c -o #{t.name}"
end
This rule will synthesize any task that ends in ".o". It has a
prerequisite a source file with an extension of ".c" must exist. If
Rake is able to find a file named "mycode.c", it will automatically
create a task that builds "mycode.o" from "mycode.c".
If the file "mycode.c" does not exist, rake will attempt
to recursively synthesize a rule for it.
When a task is synthesized from a rule, the +source+ attribute of the
task is set to the matching source file. This allows us to write
rules with actions that reference the source file.
=== Advanced Rules
Any regular expression may be used as the rule pattern. Additionally,
a proc may be used to calculate the name of the source file. This
allows for complex patterns and sources.
The following rule is equivalent to the example above.
rule( /\.o$/ => [
proc {|task_name| task_name.sub(/\.[^.]+$/, '.c') }
]) do |t|
sh "cc #{t.source} -c -o #{t.name}"
end
*NOTE:* Because of a _quirk_ in Ruby syntax, parenthesis are
required on *rule* when the first argument is a regular expression.
The following rule might be used for Java files ...
rule '.class' => [
proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') }
] do |t|
java_compile(t.source, t.name)
end
*NOTE:* +java_compile+ is a hypothetical method that invokes the
java compiler.
== Importing Dependencies
Any ruby file (including other rakefiles) can be included with a
standard Ruby +require+ command. The rules and declarations in the
required file are just added to the definitions already accumulated.
Because the files are loaded _before_ the rake targets are evaluated,
the loaded files must be "ready to go" when the rake command is
invoked. This makes generated dependency files difficult to use. By
the time rake gets around to updating the dependencies file, it is too
late to load it.
The +import+ command addresses this by specifying a file to be loaded
_after_ the main rakefile is loaded, but _before_ any targets on the
command line are invoked. In addition, if the file name matches an
explicit task, that task is invoked before loading the file. This
allows dependency files to be generated and used in a single rake
command invocation.
Example:
require 'rake/loaders/makefile'
file ".depends.mf" => [SRC_LIST] do |t|
sh "makedepend -f- -- #{CFLAGS} -- #{t.prerequisites} > #{t.name}"
end
import ".depends.mf"
If ".depends" does not exist, or is out of date w.r.t. the source
files, a new ".depends" file is generated using +makedepend+ before
loading.
== Comments
Standard Ruby comments (beginning with "#") can be used anywhere it is
legal in Ruby source code, including comments for tasks and rules.
However, if you wish a task to be described using the "-T" switch,
then you need to use the +desc+ command to describe the task.
Example:
desc "Create a distribution package"
task package: %w[ ... ] do ... end
The "-T" switch (or "--tasks" if you like to spell things out) will
display a list of tasks that have a description. If you use +desc+ to
describe your major tasks, you have a semi-automatic way of generating
a summary of your Rake file.
$ rake -T
(in /home/.../rake)
rake clean # Remove any temporary products.
rake clobber # Remove any generated file.
rake clobber_rdoc # Remove rdoc products
rake contrib_test # Run tests for contrib_test
rake default # Default Task
rake install # Install the application
rake lines # Count lines in the main rake file
rake rdoc # Build the rdoc HTML Files
rake rerdoc # Force a rebuild of the RDOC files
rake test # Run tests
rake testall # Run all test targets
Only tasks with descriptions will be displayed with the "-T" switch.
Use "-P" (or "--prereqs") to get a list of all tasks and their
prerequisites.
== Namespaces
As projects grow (and along with it, the number of tasks), it is
common for task names to begin to clash. For example, if you might
have a main program and a set of sample programs built by a single
Rakefile. By placing the tasks related to the main program in one
namespace, and the tasks for building the sample programs in a
different namespace, the task names will not interfere with each other.
For example:
namespace "main" do
task :build do
# Build the main program
end
end
namespace "samples" do
task :build do
# Build the sample programs
end
end
task build: %w[main:build samples:build]
Referencing a task in a separate namespace can be achieved by
prefixing the task name with the namespace and a colon
(e.g. "main:build" refers to the :build task in the +main+ namespace).
Nested namespaces are supported.
Note that the name given in the +task+ command is always the unadorned
task name without any namespace prefixes. The +task+ command always
defines a task in the current namespace.
=== FileTasks
File task names are not scoped by the namespace command. Since the
name of a file task is the name of an actual file in the file system,
it makes little sense to include file task names in name space.
Directory tasks (created by the +directory+ command) are a type of
file task and are also not affected by namespaces.
=== Name Resolution
When looking up a task name, rake will start with the current
namespace and attempt to find the name there. If it fails to find a
name in the current namespace, it will search the parent namespaces
until a match is found (or an error occurs if there is no match).
The "rake" namespace is a special implicit namespace that refers to
the toplevel names.
If a task name begins with a "^" character, the name resolution will
start in the parent namespace. Multiple "^" characters are allowed.
Here is an example file with multiple :run tasks and how various names
resolve in different locations.
task :run
namespace "one" do
task :run
namespace "two" do
task :run
# :run => "one:two:run"
# "two:run" => "one:two:run"
# "one:two:run" => "one:two:run"
# "one:run" => "one:run"
# "^run" => "one:run"
# "^^run" => "rake:run" (the top level task)
# "rake:run" => "rake:run" (the top level task)
end
# :run => "one:run"
# "two:run" => "one:two:run"
# "^run" => "rake:run"
end
# :run => "rake:run"
# "one:run" => "one:run"
# "one:two:run" => "one:two:run"
== FileLists
FileLists are the way Rake manages lists of files. You can treat a
FileList as an array of strings for the most part, but FileLists
support some additional operations.
=== Creating a FileList
Creating a file list is easy. Just give it the list of file names:
fl = FileList['file1.rb', file2.rb']
Or give it a glob pattern:
fl = FileList['*.rb']
== Odds and Ends
=== do/end versus { }
Blocks may be specified with either a +do+/+end+ pair, or with curly
braces in Ruby. We _strongly_ recommend using +do+/+end+ to specify the
actions for tasks and rules. Because the rakefile idiom tends to
leave off parentheses on the task/file/rule methods, unusual
ambiguities can arise when using curly braces.
For example, suppose that the method +object_files+ returns a list of
object files in a project. Now we use +object_files+ as the
prerequisites in a rule specified with actions in curly braces.
# DON'T DO THIS!
file "prog" => object_files {
# Actions are expected here (but it doesn't work)!
}
Because curly braces have a higher precedence than +do+/+end+, the
block is associated with the +object_files+ method rather than the
+file+ method.
This is the proper way to specify the task ...
# THIS IS FINE
file "prog" => object_files do
# Actions go here
end
== Rakefile Path
When issuing the +rake+ command in a terminal, Rake will look
for a Rakefile in the current directory. If a Rakefile is not found,
it will search parent directories until one is found.
For example, if a Rakefile resides in the +project/+ directory,
moving deeper into the project's directory tree will not have an adverse
effect on rake tasks:
$ pwd
/home/user/project
$ cd lib/foo/bar
$ pwd
/home/user/project/lib/foo/bar
$ rake run_pwd
/home/user/project
As far as rake is concerned, all tasks are run from the directory in
which the Rakefile resides.
=== Multiple Rake Files
Not all tasks need to be included in a single Rakefile. Additional
rake files (with the file extension "+.rake+") may be placed in
+rakelib+ directory located at the top level of a project (i.e.
the same directory that contains the main +Rakefile+).
Also, rails projects may include additional rake files in the
+lib/tasks+ directory.
=== Clean and Clobber Tasks
Through <tt>require 'rake/clean'</tt> Rake provides +clean+ and +clobber+
tasks:
+clean+ ::
Clean up the project by deleting scratch files and backup files. Add files
to the +CLEAN+ FileList to have the +clean+ target handle them.
+clobber+ ::
Clobber all generated and non-source files in a project. The task depends
on +clean+, so all the +CLEAN+ files will be deleted as well as files in the
+CLOBBER+ FileList. The intent of this task is to return a project to its
pristine, just unpacked state.
You can add file names or glob patterns to both the +CLEAN+ and +CLOBBER+
lists.
=== Phony Task
The phony task can be used as a dependency to allow file-based tasks to use
non-file-based-tasks as prerequisites without forcing them to rebuild. You
can <tt>require 'rake/phony'</tt> to add the +phony+ task.

Ok, let me state from the beginning that I never intended to write this
code. I'm not convinced it is useful, and I'm not convinced anyone
would even be interested in it. All I can say is that Why's onion truck
must by been passing through the Ohio valley.
What am I talking about? ... A Ruby version of Make.
See, I can sense you cringing already, and I agree. The world certainly
doesn't need yet another reworking of the "make" program. I mean, we
already have "ant". Isn't that enough?
It started yesterday. I was helping a coworker fix a problem in one of
the Makefiles we use in our project. Not a particularly tough problem,
but during the course of the conversation I began lamenting some of the
shortcomings of make. In particular, in one of my makefiles I wanted to
determine the name of a file dynamically and had to resort to some
simple scripting (in Ruby) to make it work. "Wouldn't it be nice if you
could just use Ruby inside a Makefile" I said.
My coworker (a recent convert to Ruby) agreed, but wondered what it
would look like. So I sketched the following on the whiteboard...
"What if you could specify the make tasks in Ruby, like this ..."
task "build" do
java_compile(...args, etc ...)
end
"The task function would register "build" as a target to be made,
and the block would be the action executed whenever the build
system determined that it was time to do the build target."
We agreed that would be cool, but writing make from scratch would be WAY
too much work. And that was the end of that!
... Except I couldn't get the thought out of my head. What exactly
would be needed to make the about syntax work as a make file? Hmmm, you
would need to register the tasks, you need some way of specifying
dependencies between tasks, and some way of kicking off the process.
Hey! What if we did ... and fifteen minutes later I had a working
prototype of Ruby make, complete with dependencies and actions.
I showed the code to my coworker and we had a good laugh. It was just
about a page worth of code that reproduced an amazing amount of the
functionality of make. We were both truly stunned with the power of
Ruby.
But it didn't do everything make did. In particular, it didn't have
timestamp based file dependencies (where a file is rebuilt if any of its
prerequisite files have a later timestamp). Obviously THAT would be a
pain to add and so Ruby Make would remain an interesting experiment.
... Except as I walked back to my desk, I started thinking about what
file based dependencies would really need. Rats! I was hooked again,
and by adding a new class and two new methods, file/timestamp
dependencies were implemented.
Ok, now I was really hooked. Last night (during CSI!) I massaged the
code and cleaned it up a bit. The result is a bare-bones replacement
for make in exactly 100 lines of code.
For the curious, you can see it at ...
* doc/proto_rake.rdoc
Oh, about the name. When I wrote the example Ruby Make task on my
whiteboard, my coworker exclaimed "Oh! I have the perfect name: Rake ...
Get it? Ruby-Make. Rake!" He said he envisioned the tasks as leaves
and Rake would clean them up ... or something like that. Anyways, the
name stuck.
Some quick examples ...
A simple task to delete backup files ...
task :clean do
Dir['*~'].each {|fn| rm fn rescue nil}
end
Note that task names are symbols (they are slightly easier to type
than quoted strings ... but you may use quoted string if you would
rather). Rake makes the methods of the FileUtils module directly
available, so we take advantage of the <tt>rm</tt> command. Also note
the use of "rescue nil" to trap and ignore errors in the <tt>rm</tt>
command.
To run it, just type "rake clean". Rake will automatically find a
Rakefile in the current directory (or above!) and will invoke the
targets named on the command line. If there are no targets explicitly
named, rake will invoke the task "default".
Here's another task with dependencies ...
task :clobber => [:clean] do
rm_r "tempdir"
end
Task :clobber depends upon task :clean, so :clean will be run before
:clobber is executed.
Files are specified by using the "file" command. It is similar to the
task command, except that the task name represents a file, and the task
will be run only if the file doesn't exist, or if its modification time
is earlier than any of its prerequisites.
Here is a file based dependency that will compile "hello.cc" to
"hello.o".
file "hello.cc"
file "hello.o" => ["hello.cc"] do |t|
srcfile = t.name.sub(/\.o$/, ".cc")
sh %{g++ #{srcfile} -c -o #{t.name}}
end
I normally specify file tasks with string (rather than symbols). Some
file names can't be represented by symbols. Plus it makes the
distinction between them more clear to the casual reader.
Currently writing a task for each and every file in the project would be
tedious at best. I envision a set of libraries to make this job
easier. For instance, perhaps something like this ...
require 'rake/ctools'
Dir['*.c'].each do |fn|
c_source_file(fn)
end
where "c_source_file" will create all the tasks need to compile all the
C source files in a directory. Any number of useful libraries could be
created for rake.
That's it. There's no documentation (other than whats in this
message). Does this sound interesting to anyone? If so, I'll continue
to clean it up and write it up and publish it on RAA. Otherwise, I'll
leave it as an interesting exercise and a tribute to the power of Ruby.
Why /might/ rake be interesting to Ruby programmers. I don't know,
perhaps ...
* No weird make syntax (only weird Ruby syntax :-)
* No need to edit or read XML (a la ant)
* Platform independent build scripts.
* Will run anywhere Ruby exists, so no need to have "make" installed.
If you stay away from the "sys" command and use things like
'ftools', you can have a perfectly platform independent
build script. Also rake is only 100 lines of code, so it can
easily be packaged along with the rest of your code.
So ... Sorry for the long rambling message. Like I said, I never
intended to write this code at all.

action ::
Code to be executed in order to perform a task. Actions in a Rakefile are
specified in a code block. (Usually delimited by +do+/+end+ pairs.)
execute ::
When a task is executed, all of its actions are performed in the order they
were defined. Note that, unlike <tt>invoke</tt>, <tt>execute</tt> always
executes the actions (without invoking or executing the prerequisites).
file task (Rake::FileTask) ::
A file task is a task whose purpose is to create a file (which has the same
name as the task). When invoked, a file task will only execute if one or
more of the following conditions are true.
1. The associated file does not exist.
2. A prerequisite has a later time stamp than the existing file.
Because normal Tasks always have the current time as timestamp, a FileTask
that has a normal Task prerequisite will always execute.
invoke ::
When a task is invoked, first we check to see if it has been invoked before.
If it has been, then nothing else is done. If this is the first time it has
been invoked, then we invoke each of its prerequisites. Finally, we check
to see if we need to execute the actions of this task by calling
Rake::Task#needed?. If the task is needed, we execute its actions.
NOTE: Prerequisites are still invoked even if the task is not needed.
prerequisites ::
Every task has a (possibly empty) set of prerequisites. A prerequisite P to
Task T is itself a task that must be invoked before Task T.
rule ::
A rule is a recipe for synthesizing a task when no task is explicitly
defined. Rules generally synthesize file tasks.
task (Rake::Task) ::
The basic unit of work in a Rakefile. A task has a name, a set of
prerequisites, and a list of actions to be performed.

=== 10.0.3
"Jim, when will Rake reach version 1.0?"
Over the past several years I've been asked that question at
conferences, panels and over twitter. Due to historical reasons (or
maybe just plain laziness) Rake has (incorrectly) been treating the
second digit of the version as the major release number. So in my head
Rake was already at version 9.
Well, it's time to fix things. This next version of Rake drops old,
crufty, backwards compatibility hacks such as top level constants, DSL
methods defined in Object and numerous other features that are just no
longer desired. It's also time to drop the leading zero from the
version number as well and call this new version of rake what it
really is: Version 10.
So, welcome to Rake 10.0!
Rake 10 is actually feature identical to the latest version of Rake 9
(that would be the version spelled 0.9.3), *except* that Rake 10 drops
all the sundry deprecated features that have accumulated over the years.
If your Rakefile is up to date and current with all the new features
of Rake 10, you are ready to go. If your Rakefile still uses a few
deprecated feeatures, feel free to use Rake 9 (0.9.3) with the same
feature set. Just be aware that future features will be in Rake 10
family line.
==== Changes
As mentioned above, there are no new features in Rake 10. However,
there are a number of features missing:
* Classic namespaces are now gone. Rake is no longer able to reflect
the options settings in the global variables ($rakefile, $show\_tasks,
$show\_prereqs, $trace, $dryrun and $silent). The
<tt>--classic-namespace</tt> option is no longer supported.
* Global constants are no longer supported. This includes
<tt>Task</tt>, <tt>FileTask</tt>, <tt>FileCreationTask</tt> and
<tt>RakeApp</tt>). The constant missing hook to warn about using
global rake constants has been removed.
* The Rake DSL methods (task, file, directory, etc) are in their own
module (Rake::DSL). The stub versions of these methods (that printed
warnings) in Object have been removed. However, the DSL methods are
added to the top-level <tt>main</tt> object. Since <tt>main</tt> is
not in the inheritance tree, the presence of the DSL methods in main
should be low impact on other libraries.
If you want to use the Rake DSL commands from your own code, just
include <tt>Rake::DSL</tt> into your own classes and modules.
* The deprecated syntax for task arguments (the one using
<tt>:needs</tt>) has been removed.
* The <tt>--reduce-compat</tt> flag has been removed (it's not needed
anymore).
* The deprecated <tt>rake/sys.rb</tt> library has been removed.
* The deprecated <tt>rake/rdoctask.rb</tt> library has been removed.
RDoc supplies its own rake task now.
* The deprecated <tt>rake/gempackagetask.rb</tt> library has been
removed. Gem supplies its own package task now.
There is one small behavioral change:
* Non-file tasks now always report the current time as their time
stamp. This is different from the previous behavior where non-file
tasks reported current time only if there were no prerequisites, and
the max prerequisite timestamp otherwise. This lead to inconsistent
and surprising behavior when adding prerequisites to tasks that in
turn were prequisites to file tasks. The new behavior is more
consistent and predictable.
==== Changes (from 0.9.3, 0.9.4, 0.9.5)
Since Rake 10 includes the changes from the last version of Rake 9,
we'll repeat the changes for versions 0.9.3 through 0.9.5 here.
===== New Features (in 0.9.3)
* Multitask tasks now use a thread pool. Use -j to limit the number of
available threads.
* Use -m to turn regular tasks into multitasks (use at your own risk).
* You can now do "Rake.add_rakelib 'dir'" in your Rakefile to
programatically add rake task libraries.
* You can specific backtrace suppression patterns (see
--suppress-backtrace)
* Directory tasks can now take prerequisites and actions
* Use --backtrace to request a full backtrace without the task trace.
* You can say "--backtrace=stdout" and "--trace=stdout" to route trace
output to standard output rather than standard error.
* Optional 'phony' target (enable with 'require 'rake/phony'") for
special purpose builds.
* Task#clear now clears task comments as well as actions and
prerequisites. Task#clear_comment will specifically target comments.
* The --all option will force -T and -D to consider all the tasks,
with and without descriptions.
===== Bug Fixes (in 0.9.3)
* Semi-colons in windows rakefile paths now work.
* Improved Control-C support when invoking multiple test suites.
* egrep method now reads files in text mode (better support for
Windows)
* Better deprecation line number reporting.
* The -W option now works with all tasks, whether they have a
description or not.
* File globs in rake should not be sorted alphabetically, independent
of file system and platform.
* Numerous internal improvements.
* Documentation typos and fixes.
===== Bug Fixes (in 0.9.4)
* Exit status with failing tests is not correctly set to non-zero.
* Simplified syntax for phony task (for older versions of RDoc).
* Stand alone FileList usage gets glob function (without loading in
extra dependencies)
===== Bug Fixes (in 0.9.5)
* --trace and --backtrace no longer swallow following task names.

=== 10.0.0
"Jim, when will Rake reach version 1.0?"
Over the past several years I've been asked that question at
conferences, panels and over twitter. Due to historical reasons (or
maybe just plain laziness) Rake has (incorrectly) been treating the
second digit of the version as the major release number. So in my head
Rake was already at version 9.
Well, it's time to fix things. This next version of Rake drops old,
crufty, backwards compatibility hacks such as top level constants, DSL
methods defined in Object and numerous other features that are just no
longer desired. It's also time to drop the leading zero from the
version number as well and call this new version of rake what it
really is: Version 10.
So, welcome to Rake 10.0!
Rake 10 is actually feature identical to the latest version of Rake 9
(that would be the version spelled 0.9.3), *except* that Rake 10 drops
all the sundry deprecated features that have accumulated over the years.
If your Rakefile is up to date and current with all the new features
of Rake 10, you are ready to go. If your Rakefile still uses a few
deprecated feeatures, feel free to use Rake 9 (0.9.3) with the same
feature set. Just be aware that future features will be in Rake 10
family line.
==== Changes in 10.0
As mentioned above, there are no new features in Rake 10. However,
there are a number of features missing:
* Classic namespaces are now gone. Rake is no longer able to reflect
the options settings in the global variables ($rakefile, $show\_tasks,
$show\_prereqs, $trace, $dryrun and $silent). The
<tt>--classic-namespace</tt> option is no longer supported.
* Global constants are no longer supported. This includes
<tt>Task</tt>, <tt>FileTask</tt>, <tt>FileCreationTask</tt> and
<tt>RakeApp</tt>). The constant missing hook to warn about using
global rake constants has been removed.
* The Rake DSL methods (task, file, directory, etc) are in their own
module (Rake::DSL). The stub versions of these methods (that printed
warnings) in Object have been removed. However, the DSL methods are
added to the top-level <tt>main</tt> object. Since <tt>main</tt> is
not in the inheritance tree, the presence of the DSL methods in main
should be low impact on other libraries.
If you want to use the Rake DSL commands from your own code, just
include <tt>Rake::DSL</tt> into your own classes and modules.
* The deprecated syntax for task arguments (the one using
<tt>:needs</tt>) has been removed.
* The <tt>--reduce-compat</tt> flag has been removed (it's not needed
anymore).
* The deprecated <tt>rake/sys.rb</tt> library has been removed.
* The deprecated <tt>rake/rdoctask.rb</tt> library has been removed.
RDoc supplies its own rake task now.
* The deprecated <tt>rake/gempackagetask.rb</tt> library has been
removed. Gem supplies its own package task now.
There is one small behavioral change:
* Non-file tasks now always report the current time as their time
stamp. This is different from the previous behavior where non-file
tasks reported current time only if there were no prerequisites, and
the max prerequisite timestamp otherwise. This lead to inconsistent
and surprising behavior when adding prerequisites to tasks that in
turn were prequisites to file tasks. The new behavior is more
consistent and predictable.
==== Changes (from 0.9.3)
Since Rake 10 includes the changes from the last version of Rake 9,
we'll repeat the changes for version 0.9.3 here.
===== New Features
* Multitask tasks now use a thread pool. Use -j to limit the number of
available threads.
* Use -m to turn regular tasks into multitasks (use at your own risk).
* You can now do "Rake.add_rakelib 'dir'" in your Rakefile to
programatically add rake task libraries.
* You can specific backtrace suppression patterns (see
--suppress-backtrace)
* Directory tasks can now take prerequisites and actions
* Use --backtrace to request a full backtrace without the task trace.
* You can say "--backtrace=stdout" and "--trace=stdout" to route trace
output to standard output rather than standard error.
* Optional 'phony' target (enable with 'require 'rake/phony'") for
special purpose builds.
* Task#clear now clears task comments as well as actions and
prerequisites. Task#clear_comment will specifically target comments.
* The --all option will force -T and -D to consider all the tasks,
with and without descriptions.
===== Bug Fixes
* Semi-colons in windows rakefile paths now work.
* Improved Control-C support when invoking multiple test suites.
* egrep method now reads files in text mode (better support for
Windows)
* Better deprecation line number reporting.
* The -W option now works with all tasks, whether they have a
description or not.
* File globs in rake should not be sorted alphabetically, independent
of file system and platform.
* Numerous internal improvements.
* Documentation typos and fixes.

=== 0.9.6
Rake version 0.9.6 contains a number of fixes mainly for merging
Rake into the Ruby source tree and fixing tests.
==== Changes
===== Bug Fixes (0.9.6)
* Better trace output when using a multi-threaded Rakefile.
* Arg parsing is now consistent for tasks and multitasks.
* Skip exit code test in versions of Ruby that don't support it well.
Changes for better integration with the Ruby source tree:

commands are no longer private methods in Object. (Suggested by
James M. Lawrence/quix)
* Rake now uses case-insensitive comparisons to find the Rakefile on Windows.
Based on patch by Roger Pack.
* Rake now requires (instead of loads) files in the test task. Patch by Cezary
Baginski.
* Fixed typos. Patches by Sean Scot August Moon and R.T. Lechow.

put the code in a Rake::DSL.environment do ... end block.
* Split rake.rb into individual files.
* Support for the --where (-W) flag for showing where a task is defined.
* Fixed quoting in test task.
(http://onestepback.org/redmine/issues/show/44,

=== 0.8.4
Rake version 0.8.4 is a bug-fix release of rake.
NOTE: The version of Rake that comes with Ruby 1.9 has diverged
slightly from the core Rake code base. Rake 0.8.4 will work
with Ruby 1.9, but is not a strict upgrade for the Rake that
comes with Ruby 1.9. A (near) future release of Rake will unify
those two codebases.
==== Letter Writing Campaign
Thanks to Aaron Patterson (@tenderlove) and Eric Hodel (@drbrain) for
their encouraging support in organizing a letter writing campaign to
lobby for the "Warning Free" release of rake 0.8.4. A special callout
goes to Jonathan D. Lord, Sr (Dr. Wingnut) whose postcard was the
first to actually reach me. (see
http://tenderlovemaking.com/2009/02/26/we-need-a-new-version-of-rake/
for details)
==== Changes
===== New Features / Enhancements in Version 0.8.4
* Case is preserved on rakefile names. (patch from James
M. Lawrence/quix)
* Improved Rakefile case insensitivity testing (patch from Luis
Lavena).
* Windows system dir search order is now: HOME, HOMEDRIVE + HOMEPATH,
APPDATA, USERPROFILE (patch from Luis Lavena)

Lavena)
===== Bug Fixes in Version 0.8.4
* Removed reference to manage_gem to fix the warning produced by the
gem package task.

=== 0.8.2
Rake version 0.8.2 is a new release of rake that includes a number of
new features and numerous bug fixes.
==== Changes
===== New Features in Version 0.8.2
* Switched from getoptlong to optparse (patches supplied by Edwin
Pratomo).
* The -T option will now attempt to dynamically sense the size of the
terminal. The -T output will only self-truncate if the output is a
tty. However, if RAKE_COLUMNS is explicitly set, it will be honored
in any case. (Patch provided by Gavin Stark).
* The following public methods have been added to rake task objects:
* task.clear -- Clear both the prerequisites and actions of the
target rake task.
* task.clear_prerequisites -- Clear all the existing prerequisites
from the target rake task.
* task.clear_actions -- Clear all the existing actions from the
target rake task.
* task.reenable -- Re-enable a task, allowing its actions to be
executed again if the task is invoked.
* Changed RDoc test task to have no default template. This makes it
easier for the tempate to pick up the template from the environment.
* Default values for task arguments can easily be specified with the
:with_defaults method. (Idea for default argument merging supplied
by (Adam Q. Salter)
===== Bug Fixes in Version 0.8.2
* Fixed bug in package task so that it will include the subdir
directory in the package for testing. (Bug found by Adam Majer)
* Fixed filename dependency order bug in test\_inspect\_pending and
test\_to\_s\_pending. (Bug found by Adam Majer)
* Fixed check for file utils options to make them immune to the
symbol/string differences. (Patch supplied by Edwin Pratomo)
* Fixed bug with rules involving multiple source, where only the first
dependency of a rule has any effect (Patch supplied by Emanuel
Indermühle)
* FileList#clone and FileList#dup have better sematics w.r.t. taint
and freeze.
* Changed from using Mutex to Monitor. Evidently Mutex causes thread
join errors when Ruby is compiled with -disable-pthreads. (Patch
supplied by Ittay Dror)
* Fixed bug in makefile parser that had problems with extra spaces in
file task names. (Patch supplied by Ittay Dror)
==== Other changes in Version 0.8.2
* Added ENV var to rake's own Rakefile to prevent OS X from including
extended attribute junk in the rake package tar file. (Bug found by
Adam Majer)
* Added a performance patch for reading large makefile dependency
files. (Patch supplied by Ittay Dror)
==== Task Argument Examples
Prior to version 0.8.0, rake was only able to handle command line
arguments of the form NAME=VALUE that were passed into Rake via the
ENV hash. Many folks had asked for some kind of simple command line
arguments, perhaps using "--" to separate regular task names from
argument values on the command line. The problem is that there was no
easy way to associate positional arguments on the command line with
different tasks. Suppose both tasks :a and :b expect a command line
argument: does the first value go with :a? What if :b is run first?
Should it then get the first command line argument.
Rake 0.8.0 solves this problem by explicitly passing values directly
to the tasks that need them. For example, if I had a release task
that required a version number, I could say:
rake release[0.8.2]
And the string "0.8.2" will be passed to the :release task. Multiple
arguments can be passed by separating them with a comma, for example:
rake name[john,doe]
Just a few words of caution. The rake task name and its arguments
need to be a single command line argument to rake. This generally
means no spaces. If spaces are needed, then the entire rake +
argument string should be quoted. Something like this:
rake "name[billy bob, smith]"
(Quoting rules vary between operating systems and shells, so make sure
you consult the proper docs for your OS/shell).
===== Tasks that Expect Parameters
Parameters are only given to tasks that are setup to expect them. In
order to handle named parameters, the task declaration syntax for
tasks has been extended slightly.
For example, a task that needs a first name and last name might be
declared as:
task :name, :first_name, :last_name
The first argument is still the name of the task (:name in this case).
The next to argumements are the names of the parameters expected by
:name (:first_name and :last_name in the example).
To access the values of the parameters, the block defining the task
behaviour can now accept a second parameter:
task :name, :first_name, :last_name do |t, args|
puts "First name is #{args.first_name}"
puts "Last name is #{args.last_name}"
end
The first argument of the block "t" is always bound to the current
task object. The second argument "args" is an open-struct like object
that allows access to the task arguments. Extra command line
arguments to a task are ignored. Missing command line arguments are
given the nil value.

=== 0.8.0/0.8.1
Rake version 0.8.0 is a new release of rake that includes serveral new
features.
==== Changes
===== New Features in Version 0.8.0
* Tasks can now receive command line parameters. See the examples
below for more details.
* Comments are limited to 80 columns on output, but full comments can
be seen by using the -D parameter. (feature suggested by Jamis
Buck).
* Explicit exit(n) calls will now set the exit status to n. (patch
provided by Stephen Touset).
* Rake is now compatible with Ruby 1.9.
Version 0.8.1 is a minor update that includes additional Ruby 1.9
compatibility fixes.

that required a version number, I could say:
rake release[0.8.0]
And the string "0.8.0" will be passed to the :release task. Multiple
arguments can be passed by separating them with a comma, for example:
rake name[john,doe]
Just a few words of caution. The rake task name and its arguments
need to be a single command line argument to rake. This generally
means no spaces. If spaces are needed, then the entire rake +
argument string should be quoted. Something like this:
rake "name[billy bob, smith]"
(Quoting rules vary between operating systems and shells, so make sure
you consult the proper docs for your OS/shell).
===== Tasks that Expect Parameters
Parameters are only given to tasks that are setup to expect them. In
order to handle named parameters, the task declaration syntax for
tasks has been extended slightly.
For example, a task that needs a first name and last name might be
declared as:
task :name, :first_name, :last_name
The first argument is still the name of the task (:name in this case).
The next to argumements are the names of the parameters expected by
:name (:first_name and :last_name in the example).
To access the values of the parameters, the block defining the task
behaviour can now accept a second parameter:
task :name, :first_name, :last_name do |t, args|
puts "First name is #{args.first_name}"
puts "Last name is #{args.last_name}"
end
The first argument of the block "t" is always bound to the current
task object. The second argument "args" is an open-struct like object
that allows access to the task arguments. Extra command line
arguments to a task are ignored. Missing command line arguments are
given the nil value.

=== 0.7.3
Rake version 0.7.3 is a minor release that includes some refactoring to better
support custom Rake applications.
==== Changes
===== New Features in Version 0.7.3
* Added the +init+ and +top_level+ methods to make the creation of custom Rake applications a bit easier. E.g.
gem 'rake', ">= 0.7.3"
require 'rake'
Rake.application.init('myrake')
task :default do
something_interesting
end
Rake.application.top_level

=== 0.7.2
Version 0.7.2 supplies a bug fix and a few minor enhancements. In
particular, the new version fixes an incompatibility with the soon to
be released Ruby 1.8.6. We strongly recommend upgrading to Rake 0.7.2
in order to be compatible with the new version of Ruby.
==== Changes
===== Bug Fixes in 0.7.2
There are quite a number of bug fixes in the new 0.7.2 version of
Rake:
* Removed dependency on internal fu_xxx functions from FileUtils.
* Error messages are now send to stderr rather than stdout (from
Payton Quackenbush).
* Better error handling on invalid command line arguments (from Payton
Quackenbush).
* Fixed some bugs where the application object was going to the global
appliation instead of using its own data.
* Fixed the method name leak from FileUtils (bug found by Glenn
Vanderburg).
* Added test for noop, bad_option and verbose flags to sh command.
* Added a description to the gem task in GemPackageTask.
* Fixed a bug when rules have multiple prerequisites (patch by Joel
VanderWerf)
* Added the handful of RakeFileUtils to the private method as well.
===== New Features in 0.7.2
The following new features are available in Rake version 0.7.2:
* Added square and curly bracket patterns to FileList#include (Tilman
Sauerbeck).
* FileLists can now pass a block to FileList#exclude to exclude files
based on calculated values.
* Added plain filename support to rule dependents (suggested by Nobu
Nakada).
* Added pathmap support to rule dependents. In other words, if a
pathmap format (beginning with a '%') is given as a Rake rule
dependent, then the name of the depend will be the name of the
target with the pathmap format applied.
* Added a 'tasks' method to a namespace to get a list of tasks
associated with the namespace.
* Added tar_command and zip_command options to the Package task.
* The clean task will no longer delete 'core' if it is a directory.
===== Internal Rake Improvements
The following changes will are mainly internal improvements and
refactorings and have little effect on the end user. But they may be
of interest to the general public.
* Added rcov task and updated unit testing for better code coverage.
* Added a 'shame' task to the Rakefile.
* Added rake_extension to handle detection of extension collisions.
* Added a protected 'require "rubygems"' to test/test_application to
unbreak cruisecontrol.rb.
* Removed rake\_dup. Now we just simply rescue a bad dup.
* Refactored the FileList reject logic to remove duplication.
* Removed if \_\_FILE\_\_ at the end of the rake.rb file.
==== Thanks

advanced file globbing.
* Nobu Nakada -- For suggesting plain file name support to rule dependents.
-- Jim Weirich
=== 0.7.1
Version 0.7.1 supplies a bug fix and a few minor enhancements.
==== Changes
===== Bug Fixes in 0.7.1
* Changes in the exception reported for the FileUtils.ln caused
safe_ln to fail with a NotImplementedError. Rake 0.7.1 will now
catch that error or any StandardError and properly fall back to
using +cp+.
===== New Features in 0.7.1
* You can filter the results of the --task option by supplying an
optional regular expression. This allows the user to easily find a
particular task name in a long list of possible names.
* Transforming procs in a rule may now return a list of prerequisites.
This allows more flexible rule formation.
* FileList and String now support a +pathmap+ melthod that makes the
transforming paths a bit easier. See the API docs for +pathmap+ for
details.
* The -f option without a value will disable the search for a
Rakefile. This allows the Rakefile to be defined entirely in a
library (and loaded with the -r option). The current working
directory is not changed when this is done.
==== Thanks
As usual, it was input from users that drove a alot of these changes.
The following people either contributed patches, made suggestions or
made otherwise helpful comments. Thanks to ...
* James Britt and Assaph Mehr for reporting and helping to debug the
safe_ln issue.
-- Jim Weirich
=== 0.7.0
These changes for Rake have been brewing for a long time. Here they
are, I hope you enjoy them.
==== Changes
===== New Features
* Name space support for task names (see below).
* Prerequisites can be executed in parallel (see below).
* Added safe_ln support for openAFS (via Ludvig Omholt).
* RDoc defaults to internal (in-process) invocation. The old behavior
is still available by setting the +external+ flag to true.
* Rakefiles are now loaded with the expanded path to prevent
accidental pollution from the Ruby load path.
* Task objects my now be used in prerequisite lists directly.
* Task objects (in addition to task names) may now be included in the
prerequisite list of a task.
* Internals cleanup and refactoring.
===== Bug Fixes
* Compatibility fixes for Ruby 1.8.4 FileUtils changes.
===== Namespaces
Tasks can now be nested inside their own namespaces. Tasks within one
namespace will not accidentally interfer with tasks named in a different
namespace.
For example:
namespace "main" do
task :build do
# Build the main program
end
end
namespace "samples" do
task :build do
# Build the sample programs
end
end
task :build_all => ["main:build", "samples:build"]
Even though both tasks are named :build, they are separate tasks in
their own namespaces. The :build_all task (defined in the toplevel
namespace) references both build tasks in its prerequisites.
You may invoke each of the individual build tasks with the following
commands:
rake main:build
rake samples:build
Or invoke both via the :build_all command:
rake build_all
Namespaces may be nested arbitrarily. Since the name of file tasks
correspond to the name of a file in the external file system,
FileTasks are not affected by the namespaces.
See the Rakefile format documentation (in the Rake API documents) for
more information.
===== Parallel Tasks
Sometimes you have several tasks that can be executed in parallel. By
specifying these tasks as prerequisites to a +multitask+ task.
In the following example the tasks copy\_src, copy\_doc and copy\_bin
will all execute in parallel in their own thread.
multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do
puts "All Copies Complete"
end
==== Thanks
As usual, it was input from users that drove a alot of these changes.
The following people either contributed patches, made suggestions or
made otherwise helpful comments. Thanks to ...
* Doug Young (inspiration for the parallel task)
* David Heinemeier Hansson (for --trace message enhancement and for
pushing for namespace support).
* Ludvig Omholt (for the openAFS fix)
-- Jim Weirich
=== 0.6.1
* Rebuilt 0.6.0 gem without signing.
=== 0.6.0
Its time for some long requested enhancements and lots of bug fixes
... And a whole new web page.
==== New Web Page
The primary documentation for rake has moved from the RubyForge based
wiki to its own Hieraki based web site. Constant spam on the wiki
made it a difficult to keep clean. The new site will be easier to
update and organize.
Check out the new documentation at: http://docs.rubyrake.org
We will be adding new documentation to the site as time goes on.
In addition to the new docs page, make sure you check out Martin
Fowlers article on rake at http://martinfowler.com/articles/rake.html
==== Changes
===== New Features
* Multiple prerequisites on Rake rules now allowed. However, keep the
following in mind:
1. All the prerequisites of a rule must be available before a rule
is triggered, where "enabled" means (a) an existing file, (b) a
defined rule, or (c) another rule which also must be
trigger-able.
2. Rules are checked in order of definition, so it is important to
order your rules properly. If a file can be created by two
different rules, put the more specific rule first (otherwise the
more general rule will trigger first and the specific one will
never be triggered).
3. The <tt>source</tt> method now returns the name of the first
prerequisite listed in the rule. <tt>sources</tt> returns the
names of all the rule prerequisites, ordered as they are defined
in the rule. If the task has other prerequisites not defined in
the rule (but defined in an explicit task definition), then they
will _not_ be included in the sources list.
* FileLists may now use the egrep command. This popular enhancement
is now a core part of the FileList object. If you want to get a
list of all your to-dos, fixmes and TBD comments, add the following
to your Rakefile.
desc "Look for TODO and FIXME tags in the code"
task :todo do
FileList['**/*.rb'].egrep /#.*(FIXME|TODO|TBD)/
end
* The <tt>investigation</tt> method was added to task object to dump
out some important values. This makes it a bit easier to debug Rake
tasks.
For example, if you are having problems with a particular task, just
print it out:
task :huh do
puts Rake::Task['huh'].investigation
end
* The Rake::TestTask class now supports a "ruby\_opts" option to pass
arbitrary ruby options to a test subprocess.
===== Some Incompatibilities
* When using the <tt>ruby</tt> command to start a Ruby subprocess, the
Ruby interpreter that is currently running rake is used by default.
This makes it easier to use rake in an environment with multiple
ruby installation. (Previously, the first ruby command found in the
PATH was used).
If you wish to chose a different Ruby interpreter, you can
explicitly choose the interpreter via the <tt>sh</tt> command.
* The major rake classes (Task, FileTask, FileCreationTask, RakeApp)
have been moved out of the toplevel scope and are now accessible as
Rake::Task, Rake::FileTask, Rake::FileCreationTask and
Rake::Application. If your Rakefile
directly references any one of these tasks, you may:
1. Update your Rakefile to use the new classnames
2. Use the --classic-namespace option on the rake command to get the
old behavior,
3. Add <code>require 'rake/classic_namespace'</code> to the
Rakefile to get the old behavior.
<tt>rake</tt> will print a rather annoying warning whenever a
deprecated class name is referenced without enabling classic
namespace.
===== Bug Fixes
* Several unit tests and functional tests were fixed to run better
under windows.
* Directory tasks are now a specialized version of a File task. A
directory task will only be triggered if it doesn't exist. It will
not be triggered if it is out of date w.r.t. any of its
prerequisites.
* Fixed a bug in the Rake::GemPackageTask class so that the gem now
properly contains the platform name.
* Fixed a bug where a prerequisite on a <tt>file</tt> task would cause
an exception if the prerequisite did not exist.

* Masao Mutch (better support for non-ruby Gem platforms)
* Philipp Neubeck (patch for file task exception fix)
-- Jim Weirich
=== 0.5.4
Time for some minor bug fixes and small enhancements
==== Changes
Here are the changes for version 0.5.4 ...
* Added double quotes to the test runner. This allows the location of
the tests (and runner) to be in a directory path that contains
spaces (e.g. "C:/Program Files/ruby/bin").
* Added .svn to default ignore list. Now subversion project metadata
is automatically ignored by Rake's FileList.
* Updated FileList#include to support nested arrays and filelists.
FileLists are flat lists of file names. Using a FileList in an
include will flatten out the nested file names.
== Thanks
As usual, it was input from users that drove a alot of these changes.
Thanks to ...
* Tilman Sauerbeck for the nested FileList suggestion.
* Josh Knowles for pointing out the spaces in directory name problem.
-- Jim Weirich
=== 0.5.3
Although it has only been two weeks since the last release, we have
enough updates to the Rake program to make it time for another
release.
==== Changes
Here are the changes for version 0.5.3 ...
* FileLists have been extensively changed so that they mimic the
behavior of real arrays even more closely. In particular,
operations on FileLists that return a new collection (e.g. collect,
reject) will now return a FileList rather than an array. In
addition, several places where FileLists were not properly expanded
before use have been fixed.
* A method (+ext+) to simplify the handling of file extensions was
added to String and to Array.
* The 'testrb' script in test/unit tends to silently swallow syntax
errors in test suites. Because of that, the default test loader is
now a rake-provided script. You can still use 'testrb' by setting
the loader flag in the test task to :testrb. (See the API documents
for TestTask for all the loader flag values).
* FileUtil methods (e.g. cp, mv, install) are now declared to be
private. This will cut down on the interference with user defined
methods of the same name.
* Fixed the verbose flag in the TestTask so that the test code is
controlled by the flag. Also shortened up some failure messages.
(Thanks to Tobias Luetke for the suggestion).
* Rules will now properly detect a task that can generate a source
file. Previously rules would only consider source files that were
already present.
* Added an +import+ command that allows Rake to dynamically import
dependendencies into a running Rake session. The +import+ command
can run tasks to update the dependency file before loading them.
Dependency files can be in rake or make format, allowing rake to
work with tools designed to generate dependencies for make.
==== Thanks
As usual, it was input from users that drove a alot of these changes.
Thanks to ...
* Brian Gernhardt for the rules fix (especially for the patience to
explain the problem to me until I got what he was talking about).
* Stefan Lang for pointing out problems in the dark corners of the
FileList implementation.
* Alexey Verkhovsky pointing out the silently swallows syntax errors
in tests.
* Tobias Luetke for beautifying the test task output.
* Sam Roberts for some of the ideas behind dependency loading.
-- Jim Weirich
=== 0.5.0
It has been a long time in coming, but we finally have a new version
of Rake available.
==== Changes
* Fixed documentation that was lacking the Rake module name (Tilman
Sauerbeck).
* Added tar.gz and tar.bz2 support to package task (Tilman Sauerbeck).
* Recursive rules are now supported (Tilman Sauerbeck).
* Added warning option for the Test Task (requested by Eric Hodel).
* The jamis rdoc template is only used if it exists.
* Added fix for Ruby 1.8.2 test/unit and rails problem.
* Added contributed rake man file (Jani Monoses).
* Added Brian Candler's fix for problems in --trace and --dry-run
mode.
==== Thanks
Lots of people provided input to this release. Thanks to Tilman
Sauerbeck for numerous patches, documentation fixes and suggestions.
And for also pushing me to get this release out. Also, thanks to
Brian Candler for the finding and fixing --trace/dry-run fix. That
was an obscure bug. Also to Eric Hodel for some good suggestions.
-- Jim Weirich
=== 0.4.15
==== Changes
Version 0.4.15 is a bug fix update for the Ruby 1.8.2 compatibility
changes. This release includes:
* Fixed a bug that prevented the TESTOPTS flag from working with the
revised for 1.8.2 test task.
* Updated the docs on --trace to indicate that it also enables a full
backtrace on errors.
* Several fixes for new warnings generated.
==== Mini-Roadmap
I will continue to issue Rake updates in the 0.4.xx series as new
Ruby-1.8.2 issues become manifest. Once the codebase stabilizes, I
will release a 0.5.0 version incorporating all the changes. If you
are not using Ruby-1.8.2 and wish to avoid version churn, I recommend
staying with a release prior to Rake-0.4.14.
=== 0.4.14
Version 0.4.14 is a compatibility fix to allow Rake's test task to
work under Ruby 1.8.2. A change in the Test::Unit autorun feature
prevented Rake from running any tests. This release fixes the
problem.
Rake 0.4.14 is the recommended release for anyone using Ruby 1.8.2.
=== 0.4.13
* Fixed the dry-run flag so it is operating again.
* Multiple arguments to sh and ruby commands will not be interpreted
by the shell (patch provided by Jonathan Paisley).
=== 0.4.12
* Added --silent (-s) to suppress the (in directory) rake message.
=== 0.4.11
* Changed the "don't know how to rake" message (finally)
* Changes references to a literal "Rakefile" to reference the global
variable $rakefile (which contains the actual name of the rakefile).
=== 0.4.10
* Added block support to the "sh" command, allowing users to take
special actions on the result of the system call. E.g.
sh "shell_command" do |ok, res|
puts "Program returned #{res.exitstatus}" if ! ok
end
=== 0.4.9
* Switched to Jamis Buck's RDoc template.
* Removed autorequire from Rake's gem spec. This prevents the Rake
libraries from loading while using rails.
=== 0.4.8
* Added support for .rb versions of Rakefile.
* Removed \\\n's from test task.
* Fixed Ruby 1.9 compatibility issue with FileList.
=== 0.4.7
* Fixed problem in FileList that caused Ruby 1.9 to go into infinite
recursion. Since to_a was removed from Object, it does not need to
added back into the list of methods to rewrite in FileList. (Thanks
to Kent Sibilev for pointing this out).
=== 0.4.6
* Removed test version of ln in FileUtils that prevented safe_ln from
using ln.
=== 0.4.5
* Upgraded comments in TestTask.
* FileList to_s and inspect now automatically resolve pending changes.
* FileList#exclude properly returns the FileList.
=== 0.4.4
* Fixed initialization problem with @comment.
* Now using multi -r technique in TestTask. Switch Rakefile back to
using the built-in test task macros because the rake runtime is no
longer needed.
* Added 'TEST=filename' and 'TESTOPTS=options' to the Test Task
macros.
* Allow a +test_files+ attribute in test tasks. This allows more
flexibility in specifying test files.
=== 0.4.3
* Fixed Comment leakage.
=== 0.4.2
* Added safe_ln that falls back to a copy if a file link is not supported.
* Package builder now uses safe\_ln.
=== 0.4.1
* Task comments are now additive, combined with "/".
* Works with (soon to be released) rubygems 0.6.2 (or 0.7.0)
=== 0.4.0
* FileList now uses deferred loading. The file system is not searched
until the first call that needs the file names.
* VAR=VALUE options are now accepted on the command line and are
treated like environment variables. The values may be tested in a
Rakefile by referencing ENV['VAR'].
* File.mtime is now used (instead of File.new().mtime).
=== 0.3.2.x
* Removed some hidden dependencies on rubygems. Tests now will test
gems only if they are installed.
* Removed Sys from some example files. I believe that is that last
reference to Sys outside of the contrib area.
* Updated all copyright notices to include 2004.
=== 0.3.2
* GEM Installation now works with the application stub.
=== 0.3.1
* FileLists now automatically ignore CVS, .bak, !
* GEM Installation now works.
=== 0.3.0
Promoted 0.2.10.
=== 0.2.10
General
* Added title to Rake's rdocs
* Contrib packages are no longer included in the documentation.
RDoc Issues
* Removed default for the '--main' option
* Fixed rendering of the rdoc options
* Fixed clean/clobber confusion with rerdoc
* 'title' attribute added
Package Task Library Issues
* Version (or explicit :noversion) is required.
* +package_file+ attribute is now writable
FileList Issues
* Dropped bang version of exclude. Now using ant-like include/exclude semantics.
* Enabled the "yield self" idiom in FileList#initialize.
=== 0.2.9
This version contains numerous changes as the RubyConf.new(2003)
presentation was being prepared. The changes include:
* The monolithic rubyapp task library is in the process of being
dropped in favor of lighter weight task libraries.
=== 0.2.7
* Added "desc" for task descriptions.
* -T will now display tasks with descriptions.
* -P will display tasks and prerequisites.
* Dropped the Sys module in favor of the 1.8.x FileUtils module. Sys
is still supported in the contrib area.
=== 0.2.6
* Moved to RubyForge
=== 0.2.5
* Switched to standard ruby app builder.
* Added no_match option to file matcher.
=== 0.2.4
* Fixed indir, which neglected to actually change directories.
=== 0.2.3
* Added rake module for a help target
* Added 'for\_files' to Sys
* Added a $rakefile constant
* Added test for selecting proper rule with multiple targets.

docs :: https://ruby.github.io/rake
== Description
Rake is a Make-like program implemented in Ruby. Tasks and dependencies are
specified in standard Ruby syntax.
Rake has the following features:
* Rakefiles (rake's version of Makefiles) are completely defined in
standard Ruby syntax. No XML files to edit. No quirky Makefile
syntax to worry about (is that a tab or a space?)
* Users can specify tasks with prerequisites.
* Rake supports rule patterns to synthesize implicit tasks.
* Flexible FileLists that act like arrays but know about manipulating
file names and paths.
* A library of prepackaged tasks to make building rakefiles easier. For example,
tasks for building tarballs. (Formerly
tasks for building RDoc, Gems, and publishing to FTP were included in rake but they're now
available in RDoc, RubyGems, and rake-contrib respectively.)
* Supports parallel execution of tasks.
== Installation
=== Gem Installation
Download and install rake with the following.
gem install rake
== Usage
=== Simple Example
First, you must write a "Rakefile" file which contains the build rules. Here's
a simple example:
task default: %w[test]
task :test do
ruby "test/unittest.rb"
end
This Rakefile has two tasks:
* A task named "test", which -- upon invocation -- will run a unit test file
in Ruby.
* A task named "default". This task does nothing by itself, but it has exactly
one dependency, namely the "test" task. Invoking the "default" task will
cause Rake to invoke the "test" task as well.
Running the "rake" command without any options will cause it to run the
"default" task in the Rakefile:
% ls
Rakefile test/
% rake
(in /home/some_user/Projects/rake)
ruby test/unittest.rb
....unit test output here...
Type "rake --help" for all available options.

# <tt>%p</tt> :: The complete path.
# <tt>%f</tt> :: The base file name of the path, with its file extension,
# but without any directories.
# <tt>%n</tt> :: The file name of the path without its file extension.
# <tt>%d</tt> :: The directory list of the path.
# <tt>%x</tt> :: The file extension of the path. An empty string if there
# is no extension.
# <tt>%X</tt> :: Everything *but* the file extension.
# <tt>%s</tt> :: The alternate file separator if defined, otherwise use #
# the standard file separator.
# <tt>%%</tt> :: A percent sign.
#
# The <tt>%d</tt> specifier can also have a numeric prefix (e.g. '%2d').
# If the number is positive, only return (up to) +n+ directories in the
# path, starting from the left hand side. If +n+ is negative, return (up
# to) +n+ directories from the right hand side of the path.
#
# Examples:
#
# 'a/b/c/d/file.txt'.pathmap("%2d") => 'a/b'
# 'a/b/c/d/file.txt'.pathmap("%-2d") => 'c/d'
#
# Also the <tt>%d</tt>, <tt>%p</tt>, <tt>%f</tt>, <tt>%n</tt>,
# <tt>%x</tt>, and <tt>%X</tt> operators can take a pattern/replacement
# argument to perform simple string substitutions on a particular part of
# the path. The pattern and replacement are separated by a comma and are
# enclosed by curly braces. The replacement spec comes after the %
# character but before the operator letter. (e.g. "%{old,new}d").
# Multiple replacement specs should be separated by semi-colons (e.g.
# "%{old,new;src,bin}d").
#
# Regular expressions may be used for the pattern, and back refs may be
# used in the replacement text. Curly braces, commas and semi-colons are
# excluded from both the pattern and replacement text (let's keep parsing
# reasonable).
#
# For example:
#
# "src/org/onestepback/proj/A.java".pathmap("%{^src,class}X.class")
#
# returns:
#
# "class/org/onestepback/proj/A.class"
#
# If the replacement text is '*', then a block may be provided to perform
# some arbitrary calculation for the replacement.
#
# For example:
#
# "/path/to/file.TXT".pathmap("%X%{.*,*}x") { |ext|
# ext.downcase
# }
#
# Returns:
#
# "/path/to/file.txt"

##
# A FileList is essentially an array with a few helper methods defined to
# make file manipulation a bit easier.
#
# FileLists are lazy. When given a list of glob patterns for possible files
# to be included in the file list, instead of searching the file structures
# to find the files, a FileList holds the pattern for latter use.
#
# This allows us to define a number of FileList to match any number of
# files, but only search out the actual files when then FileList itself is
# actually used. The key is that the first time an element of the
# FileList/Array is requested, the pending patterns are resolved into a real
# list of file names.
#
class FileList

# == Method Delegation
#
# The lazy evaluation magic of FileLists happens by implementing all the
# array specific methods to call +resolve+ before delegating the heavy
# lifting to an embedded array object (@items).
#
# In addition, there are two kinds of delegation calls. The regular kind
# delegates to the @items array and returns the result directly. Well,
# almost directly. It checks if the returned value is the @items object
# itself, and if so will return the FileList object instead.
#
# The second kind of delegation call is used in methods that normally
# return a new Array object. We want to capture the return value of these
# methods and wrap them in a new FileList object. We enumerate these
# methods in the +SPECIAL_RETURN+ list below.
# List of array methods (that are not in +Object+) that need to be
# delegated.
ARRAY_METHODS = (Array.instance_methods - Object.instance_methods).map(&:to_s)
# List of additional methods that must be delegated.
MUST_DEFINE = %w[inspect <=>]
# List of methods that should not be delegated here (we define special
# versions of them explicitly below).
MUST_NOT_DEFINE = %w[to_a to_ary partition * <<]
# List of delegated methods that return new array values which need
# wrapping.

# Bundler provides a consistent environment for Ruby projects by
# tracking and installing the exact gems and versions that are needed.
#
# Since Ruby 2.6, Bundler is a part of Ruby's standard library.
#
# Bunder is used by creating _gemfiles_ listing all the project dependencies
# and (optionally) their versions and then using
#
# require 'bundler/setup'
#
# or Bundler.setup to setup environment where only specified gems and their
# specified versions could be used.
#
# See {Bundler website}[https://bundler.io/docs.html] for extensive documentation
# on gemfiles creation and Bundler usage.
#
# As a standard library inside project, Bundler could be used for introspection
# of loaded and required modules.

===========================================================================
## SYNOPSIS
`bundle remove [GEM [GEM ...]] [--install]`
## DESCRIPTION
Removes the given gems from the Gemfile while ensuring that the resulting Gemfile is still valid. If a gem cannot be removed, a warning is printed. If a gem is already absent from the Gemfile, and error is raised.
## OPTIONS
* `--install`:
Runs `bundle install` after the given gems have been removed from the Gemfile, which ensures that both the lockfile and the installed gems on disk are also updated to remove the given gem(s).
Example:
bundle remove rails
bundle remove rails rack
bundle remove rails rack --install

=========================================================================
## SYNOPSIS
`bundle inject` [GEM] [VERSION]
## DESCRIPTION
Adds the named gem(s) with their version requirements to the resolved
[`Gemfile(5)`][Gemfile(5)].
This command will add the gem to both your [`Gemfile(5)`][Gemfile(5)] and Gemfile.lock if it
isn't listed yet.
Example:
bundle install
bundle inject 'rack' '> 0'
This will inject the 'rack' gem with a version greater than 0 in your
[`Gemfile(5)`][Gemfile(5)] and Gemfile.lock

=======================================================================
## SYNOPSIS
`bundle outdated` [GEM] [--local]
[--pre]
[--source]
[--strict]
[--parseable | --porcelain]
[--group=GROUP]
[--groups]
[--update-strict]
[--patch|--minor|--major]
[--filter-major]
[--filter-minor]
[--filter-patch]
[--only-explicit]
## DESCRIPTION
Outdated lists the names and versions of gems that have a newer version available
in the given source. Calling outdated with [GEM [GEM]] will only check for newer
versions of the given gems. Prerelease gems are ignored by default. If your gems
are up to date, Bundler will exit with a status of 0. Otherwise, it will exit 1.
## OPTIONS
* `--local`:
Do not attempt to fetch gems remotely and use the gem cache instead.
* `--pre`:
Check for newer pre-release gems.
* `--source`:
Check against a specific source.
* `--strict`:
Only list newer versions allowed by your Gemfile requirements.
* `--parseable`, `--porcelain`:
Use minimal formatting for more parseable output.
* `--group`:
List gems from a specific group.
* `--groups`:
List gems organized by groups.
* `--update-strict`:
Strict conservative resolution, do not allow any gem to be updated past latest --patch | --minor| --major.
* `--minor`:
Prefer updating only to next minor version.
* `--major`:
Prefer updating to next major version (default).
* `--patch`:
Prefer updating only to next patch version.
* `--filter-major`:
Only list major newer versions.
* `--filter-minor`:
Only list minor newer versions.
* `--filter-patch`:
Only list patch newer versions.
* `--only-explicit`:
Only list gems specified in your Gemfile, not their dependencies.
## PATCH LEVEL OPTIONS
See [bundle update(1)](bundle-update.1.html) for details.
One difference between the patch level options in `bundle update` and here is the `--strict` option.
`--strict` was already an option on outdated before the patch level options were added. `--strict`
wasn't altered, and the `--update-strict` option on `outdated` reflects what `--strict` does on
`bundle update`.
## FILTERING OUTPUT
The 3 filtering options do not affect the resolution of versions, merely what versions are shown
in the output.
If the regular output shows the following:
* faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test"
* hashie (newest 3.4.6, installed 1.2.0, requested = 1.2.0) in groups "default"
* headless (newest 2.3.1, installed 2.2.3) in groups "test"
`--filter-major` would only show:
* hashie (newest 3.4.6, installed 1.2.0, requested = 1.2.0) in groups "default"
`--filter-minor` would only show:
* headless (newest 2.3.1, installed 2.2.3) in groups "test"
`--filter-patch` would only show:
* faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test"
Filter options can be combined. `--filter-minor` and `--filter-patch` would show:
* faker (newest 1.6.6, installed 1.6.5, requested ~> 1.4) in groups "development, test"
* headless (newest 2.3.1, installed 2.2.3) in groups "test"
Combining all three `filter` options would be the same result as providing none of them.

=========================================================
## SYNOPSIS
`bundle doctor` [--quiet]
[--gemfile=GEMFILE]
## DESCRIPTION
Checks your Gemfile and gem environment for common problems. If issues
are detected, Bundler prints them and exits status 1. Otherwise,
Bundler prints a success message and exits status 0.
Examples of common problems caught by bundle-doctor include:
* Invalid Bundler settings
* Mismatched Ruby versions
* Mismatched platforms
* Uninstalled gems
* Missing dependencies
## OPTIONS
* `--quiet`:
Only output warnings and errors.
* `--gemfile=<gemfile>`:
The location of the Gemfile(5) which Bundler should use. This defaults
to a Gemfile(5) in the current working directory. In general, Bundler
will assume that the location of the Gemfile(5) is also the project's
root and will try to find `Gemfile.lock` and `vendor/cache` relative
to this location.

===========================================================================
## SYNOPSIS
`bundle cache`
## DESCRIPTION
Copy all of the `.gem` files needed to run the application into the
`vendor/cache` directory. In the future, when running [bundle install(1)][bundle-install],
use the gems in the cache in preference to the ones on `rubygems.org`.
## GIT AND PATH GEMS
The `bundle cache` command can also package `:git` and `:path` dependencies
besides .gem files. This needs to be explicitly enabled via the `--all` option.
Once used, the `--all` option will be remembered.
## SUPPORT FOR MULTIPLE PLATFORMS
When using gems that have different packages for different platforms, Bundler
supports caching of gems for other platforms where the Gemfile has been resolved
(i.e. present in the lockfile) in `vendor/cache`. This needs to be enabled via
the `--all-platforms` option. This setting will be remembered in your local
bundler configuration.
## REMOTE FETCHING
By default, if you run `bundle install(1)`](bundle-install.1.html) after running
[bundle cache(1)](bundle-cache.1.html), bundler will still connect to `rubygems.org`
to check whether a platform-specific gem exists for any of the gems
in `vendor/cache`.
For instance, consider this Gemfile(5):
source "https://rubygems.org"
gem "nokogiri"
If you run `bundle cache` under C Ruby, bundler will retrieve
the version of `nokogiri` for the `"ruby"` platform. If you deploy
to JRuby and run `bundle install`, bundler is forced to check to
see whether a `"java"` platformed `nokogiri` exists.
Even though the `nokogiri` gem for the Ruby platform is
_technically_ acceptable on JRuby, it has a C extension
that does not run on JRuby. As a result, bundler will, by default,
still connect to `rubygems.org` to check whether it has a version
of one of your gems more specific to your platform.
This problem is also not limited to the `"java"` platform.
A similar (common) problem can happen when developing on Windows
and deploying to Linux, or even when developing on OSX and
deploying to Linux.
If you know for sure that the gems packaged in `vendor/cache`
are appropriate for the platform you are on, you can run
`bundle install --local` to skip checking for more appropriate
gems, and use the ones in `vendor/cache`.
One way to be sure that you have the right platformed versions
of all your gems is to run `bundle cache` on an identical
machine and check in the gems. For instance, you can run
`bundle cache` on an identical staging box during your
staging process, and check in the `vendor/cache` before
deploying to production.
By default, [bundle cache(1)](bundle-cache.1.html) fetches and also
installs the gems to the default location. To package the
dependencies to `vendor/cache` without installing them to the
local install location, you can run `bundle cache --no-install`.

.
.P
As you can see, even though you have two gems in the Gemfile(5), your application needs 26 different gems in order to run\. Bundler remembers the exact versions it installed in \fBGemfile\.lock\fR\. The next time you run bundle install(1) \fIbundle\-install\.1\.html\fR, bundler skips the dependency resolution and installs the same gems as it installed last time\.
.
.P
After checking in the \fBGemfile\.lock\fR into version control and cloning it on another machine, running bundle install(1) \fIbundle\-install\.1\.html\fR will \fIstill\fR install the gems that you installed last time\. You don\'t need to worry that a new release of \fBerubis\fR or \fBmail\fR changes the gems you use\.
.
.P
However, from time to time, you might want to update the gems you are using to the newest versions that still match the gems in your Gemfile(5)\.
.
.P
To do this, run \fBbundle update \-\-all\fR, which will ignore the \fBGemfile\.lock\fR, and resolve all the dependencies again\. Keep in mind that this process can result in a significantly different set of the 25 gems, based on the requirements of new gems that the gem authors released since the last time you ran \fBbundle update \-\-all\fR\.
.
.SH "UPDATING A LIST OF GEMS"
Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\.
.
.P
For instance, in the scenario above, imagine that \fBnokogiri\fR releases version \fB1\.4\.4\fR, and you want to update it \fIwithout\fR updating Rails and all of its dependencies\. To do this, run \fBbundle update nokogiri\fR\.
.
.P
Bundler will update \fBnokogiri\fR and any of its dependencies, but leave alone Rails and its dependencies\.
.
.SH "OVERLAPPING DEPENDENCIES"
Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same second\-level dependency\. For instance, consider the case of \fBthin\fR and \fBrack\-perftools\-profiler\fR\.
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
gem "thin"
gem "rack\-perftools\-profiler"
.
.fi
.
.IP "" 0
.
.P
The \fBthin\fR gem depends on \fBrack >= 1\.0\fR, while \fBrack\-perftools\-profiler\fR depends on \fBrack ~> 1\.0\fR\. If you run bundle install, you get:
.
.IP "" 4
.
.nf
Fetching source index for https://rubygems\.org/

Installing thin (1\.2\.7) with native extensions
Using bundler (1\.0\.0\.rc\.3)
.
.fi
.
.IP "" 0
.
.P
In this case, the two gems have their own set of dependencies, but they share \fBrack\fR in common\. If you run \fBbundle update thin\fR, bundler will update \fBdaemons\fR, \fBeventmachine\fR and \fBrack\fR, which are dependencies of \fBthin\fR, but not \fBopen4\fR or \fBperftools\.rb\fR, which are dependencies of \fBrack\-perftools_profiler\fR\. Note that \fBbundle update thin\fR will update \fBrack\fR even though it\'s \fIalso\fR a dependency of \fBrack\-perftools_profiler\fR\.
.
.P
In short, by default, when you update a gem using \fBbundle update\fR, bundler will update all dependencies of that gem, including those that are also dependencies of another gem\.
.
.P
To prevent updating indirect dependencies, prior to version 1\.14 the only option was the \fBCONSERVATIVE UPDATING\fR behavior in bundle install(1) \fIbundle\-install\.1\.html\fR:
.
.P
In this scenario, updating the \fBthin\fR version manually in the Gemfile(5), and then running bundle install(1) \fIbundle\-install\.1\.html\fR will only update \fBdaemons\fR and \fBeventmachine\fR, but not \fBrack\fR\. For more information, see the \fBCONSERVATIVE UPDATING\fR section of bundle install(1) \fIbundle\-install\.1\.html\fR\.
.
.P
Starting with 1\.14, specifying the \fB\-\-conservative\fR option will also prevent indirect dependencies from being updated\.
.
.SH "PATCH LEVEL OPTIONS"
Version 1\.14 introduced 4 patch\-level options that will influence how gem versions are resolved\. One of the following options can be used: \fB\-\-patch\fR, \fB\-\-minor\fR or \fB\-\-major\fR\. \fB\-\-strict\fR can be added to further influence resolution\.
.
.TP
\fB\-\-patch\fR
Prefer updating only to next patch version\.
.
.TP
\fB\-\-minor\fR
Prefer updating only to next minor version\.
.
.TP
\fB\-\-major\fR
Prefer updating to next major version (default)\.
.
.TP
\fB\-\-strict\fR
Do not allow any gem to be updated past latest \fB\-\-patch\fR | \fB\-\-minor\fR | \fB\-\-major\fR\.
.
.P
When Bundler is resolving what versions to use to satisfy declared requirements in the Gemfile or in parent gems, it looks up all available versions, filters out any versions that don\'t satisfy the requirement, and then, by default, sorts them from newest to oldest, considering them in that order\.
.
.P
Providing one of the patch level options (e\.g\. \fB\-\-patch\fR) changes the sort order of the satisfying versions, causing Bundler to consider the latest \fB\-\-patch\fR or \fB\-\-minor\fR version available before other versions\. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph\.
.
.P
For example, if gem \'foo\' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
.
.P
If the \fB\-\-patch\fR option is used, the order of preference will change to "1\.0\.4, 1\.0\.3, 1\.0\.2, 1\.1\.1, 1\.1\.0, 2\.0\.0"\.
.
.P
If the \fB\-\-minor\fR option is used, the order of preference will change to "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2, 2\.0\.0"\.

Combining the \fB\-\-strict\fR option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far\.
.
.P
To continue the previous example, if both \fB\-\-patch\fR and \fB\-\-strict\fR options are used, the available versions for resolution would be "1\.0\.4, 1\.0\.3, 1\.0\.2"\. If \fB\-\-minor\fR and \fB\-\-strict\fR are used, it would be "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
.
.P
Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available\. If the gem requirement for \fBfoo\fR in the Gemfile is \'~> 1\.0\', that will accomplish the same thing as providing the \fB\-\-minor\fR and \fB\-\-strict\fR options\.

In case 1, bar is upgraded to 2\.1\.1, a minor version increase, because the dependency from foo 1\.4\.5 required it\.

In case 2, only foo is requested to be unlocked, but bar is also allowed to move because it\'s not a declared dependency in the Gemfile\.
.

In case 3, bar goes up a whole major release, because a minor increase is preferred now for foo, and when it goes to 1\.5\.1, it requires 3\.0\.0 of bar\.
.
.P
In case 4, foo is preferred up to a minor version, but 1\.5\.1 won\'t work because the \-\-strict flag removes bar 3\.0\.0 from consideration since it\'s a major increment\.
.
.P
In case 5, both foo and bar have any minor or major increments removed from consideration because of the \-\-strict flag, so the most they can move is up to 1\.4\.4 and 2\.0\.4\.

===========================================================================
## SYNOPSIS
`bundle pristine`
## DESCRIPTION
`pristine` restores the installed gems in the bundle to their pristine condition
using the local gem cache from RubyGems. For git gems, a forced checkout will be performed.
For further explanation, `bundle pristine` ignores unpacked files on disk. In other
words, this command utilizes the local `.gem` cache or the gem's git repository
as if one were installing from scratch.
Note: the Bundler gem cannot be restored to its original state with `pristine`.
One also cannot use `bundle pristine` on gems with a 'path' option in the Gemfile,
because bundler has no original copy it can restore from.
When is it practical to use `bundle pristine`?
It comes in handy when a developer is debugging a gem. `bundle pristine` is a
great way to get rid of experimental changes to a gem that one may not want.
Why use `bundle pristine` over `gem pristine --all`?
Both commands are very similar.
For context: `bundle pristine`, without arguments, cleans all gems from the lockfile.
Meanwhile, `gem pristine --all` cleans all installed gems for that Ruby version.
If a developer forgets which gems in their project they might
have been debugging, the Rubygems `gem pristine [GEMNAME]` command may be inconvenient.
One can avoid waiting for `gem pristine --all`, and instead run `bundle pristine`.

=============================================================
## SYNOPSIS
`bundle binstubs` <GEM_NAME> [--force] [--path PATH] [--standalone]
## DESCRIPTION
Binstubs are scripts that wrap around executables. Bundler creates a
small Ruby file (a binstub) that loads Bundler, runs the command,
and puts it into `bin/`. Binstubs are a shortcut-or alternative-
to always using `bundle exec`. This gives you a file that can be run
directly, and one that will always run the correct gem version
used by the application.
For example, if you run `bundle binstubs rspec-core`, Bundler will create
the file `bin/rspec`. That file will contain enough code to load Bundler,
tell it to load the bundled gems, and then run rspec.
This command generates binstubs for executables in `GEM_NAME`.
Binstubs are put into `bin`, or the `--path` directory if one has been set.
Calling binstubs with [GEM [GEM]] will create binstubs for all given gems.
## OPTIONS
* `--force`:
Overwrite existing binstubs if they exist.
* `--path`:
The location to install the specified binstubs to. This defaults to `bin`.
* `--standalone`:
Makes binstubs that can work without depending on Rubygems or Bundler at
runtime.
* `--shebang`:
Specify a different shebang executable name than the default (default 'ruby')
* `--all`:
Create binstubs for all gems in the bundle.

========================================================================
## SYNOPSIS
A `Gemfile` describes the gem dependencies required to execute associated
Ruby code.
Place the `Gemfile` in the root of the directory containing the associated
code. For instance, in a Rails application, place the `Gemfile` in the same
directory as the `Rakefile`.
## SYNTAX
A `Gemfile` is evaluated as Ruby code, in a context which makes available
a number of methods used to describe the gem requirements.
## GLOBAL SOURCES
At the top of the `Gemfile`, add a line for the `Rubygems` source that contains
the gems listed in the `Gemfile`.
source "https://rubygems.org"
It is possible, but not recommended as of Bundler 1.7, to add multiple global
`source` lines. Each of these `source`s `MUST` be a valid Rubygems repository.
Sources are checked for gems following the heuristics described in
[SOURCE PRIORITY][]. If a gem is found in more than one global source, Bundler
will print a warning after installing the gem indicating which source was used,
and listing the other sources where the gem is available. A specific source can
be selected for gems that need to use a non-standard repository, suppressing
this warning, by using the [`:source` option](#SOURCE) or a
[`source` block](#BLOCK-FORM-OF-SOURCE-GIT-PATH-GROUP-and-PLATFORMS).
### CREDENTIALS
Some gem sources require a username and password. Use [bundle config(1)](bundle-config.1.html) to set
the username and password for any of the sources that need it. The command must
be run once on each computer that will install the Gemfile, but this keeps the
credentials from being stored in plain text in version control.
bundle config gems.example.com user:password
For some sources, like a company Gemfury account, it may be easier to
include the credentials in the Gemfile as part of the source URL.
source "https://user:password@gems.example.com"
Credentials in the source URL will take precedence over credentials set using
`config`.
## RUBY
If your application requires a specific Ruby version or engine, specify your
requirements using the `ruby` method, with the following arguments.
All parameters are `OPTIONAL` unless otherwise specified.
### VERSION (required)
The version of Ruby that your application requires. If your application
requires an alternate Ruby engine, such as JRuby, Rubinius or TruffleRuby, this
should be the Ruby version that the engine is compatible with.
ruby "1.9.3"
### ENGINE
Each application _may_ specify a Ruby engine. If an engine is specified, an
engine version _must_ also be specified.
What exactly is an Engine?
- A Ruby engine is an implementation of the Ruby language.
- For background: the reference or original implementation of the Ruby
programming language is called
[Matz's Ruby Interpreter](https://en.wikipedia.org/wiki/Ruby_MRI), or MRI
for short. This is named after Ruby creator Yukihiro Matsumoto,
also known as Matz. MRI is also known as CRuby, because it is written in C.
MRI is the most widely used Ruby engine.
- [Other implementations](https://www.ruby-lang.org/en/about/) of Ruby exist.
Some of the more well-known implementations include
[Rubinius](https://rubinius.com/), and [JRuby](http://jruby.org/).
Rubinius is an alternative implementation of Ruby written in Ruby.
JRuby is an implementation of Ruby on the JVM, short for Java Virtual Machine.
### ENGINE VERSION
Each application _may_ specify a Ruby engine version. If an engine version is
specified, an engine _must_ also be specified. If the engine is "ruby" the
engine version specified _must_ match the Ruby version.
ruby "1.8.7", :engine => "jruby", :engine_version => "1.6.7"
### PATCHLEVEL
Each application _may_ specify a Ruby patchlevel.
ruby "2.0.0", :patchlevel => "247"
## GEMS
Specify gem requirements using the `gem` method, with the following arguments.
All parameters are `OPTIONAL` unless otherwise specified.
### NAME (required)
For each gem requirement, list a single _gem_ line.
gem "nokogiri"
### VERSION
Each _gem_ `MAY` have one or more version specifiers.
gem "nokogiri", ">= 1.4.2"
gem "RedCloth", ">= 4.1.0", "< 4.2.0"
### REQUIRE AS
Each _gem_ `MAY` specify files that should be used when autorequiring via
`Bundler.require`. You may pass an array with multiple files or `true` if the file
you want `required` has the same name as _gem_ or `false` to
prevent any file from being autorequired.
gem "redis", :require => ["redis/connection/hiredis", "redis"]
gem "webmock", :require => false
gem "byebug", :require => true
The argument defaults to the name of the gem. For example, these are identical:
gem "nokogiri"
gem "nokogiri", :require => "nokogiri"
gem "nokogiri", :require => true
### GROUPS
Each _gem_ `MAY` specify membership in one or more groups. Any _gem_ that does
not specify membership in any group is placed in the `default` group.
gem "rspec", :group => :test
gem "wirble", :groups => [:development, :test]
The Bundler runtime allows its two main methods, `Bundler.setup` and
`Bundler.require`, to limit their impact to particular groups.
# setup adds gems to Ruby's load path
Bundler.setup # defaults to all groups
require "bundler/setup" # same as Bundler.setup
Bundler.setup(:default) # only set up the _default_ group
Bundler.setup(:test) # only set up the _test_ group (but `not` _default_)
Bundler.setup(:default, :test) # set up the _default_ and _test_ groups, but no others
# require requires all of the gems in the specified groups
Bundler.require # defaults to the _default_ group
Bundler.require(:default) # identical
Bundler.require(:default, :test) # requires the _default_ and _test_ groups
Bundler.require(:test) # requires the _test_ group
The Bundler CLI allows you to specify a list of groups whose gems `bundle install` should
not install with the `without` configuration.
To specify multiple groups to ignore, specify a list of groups separated by spaces.
bundle config set --local without test
bundle config set --local without development test
Also, calling `Bundler.setup` with no parameters, or calling `require "bundler/setup"`
will setup all groups except for the ones you excluded via `--without` (since they
are not available).
Note that on `bundle install`, bundler downloads and evaluates all gems, in order to
create a single canonical list of all of the required gems and their dependencies.
This means that you cannot list different versions of the same gems in different
groups. For more details, see [Understanding Bundler](https://bundler.io/rationale.html).
### PLATFORMS
If a gem should only be used in a particular platform or set of platforms, you can
specify them. Platforms are essentially identical to groups, except that you do not
need to use the `--without` install-time flag to exclude groups of gems for other
platforms.
There are a number of `Gemfile` platforms:
* `ruby`:
C Ruby (MRI), Rubinius or TruffleRuby, but `NOT` Windows
* `mri`:
Same as _ruby_, but only C Ruby (MRI)
* `mingw`:
Windows 32 bit 'mingw32' platform (aka RubyInstaller)
* `x64_mingw`:
Windows 64 bit 'mingw32' platform (aka RubyInstaller x64)
* `rbx`:
Rubinius
* `jruby`:
JRuby
* `truffleruby`:
TruffleRuby
* `mswin`:
Windows
You can restrict further by platform and version for all platforms *except* for
`rbx`, `jruby`, `truffleruby` and `mswin`.
To specify a version in addition to a platform, append the version number without
the delimiter to the platform. For example, to specify that a gem should only be
used on platforms with Ruby 2.3, use:
ruby_23
The full list of platforms and supported versions includes:
* `ruby`:
1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6
* `mri`:
1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6
* `mingw`:
1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6
* `x64_mingw`:
2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6
As with groups, you can specify one or more platforms:
gem "weakling", :platforms => :jruby
gem "ruby-debug", :platforms => :mri_18
gem "nokogiri", :platforms => [:mri_18, :jruby]
All operations involving groups ([`bundle install`](bundle-install.1.html), `Bundler.setup`,
`Bundler.require`) behave exactly the same as if any groups not
matching the current platform were explicitly excluded.
### SOURCE
You can select an alternate Rubygems repository for a gem using the ':source'
option.
gem "some_internal_gem", :source => "https://gems.example.com"
This forces the gem to be loaded from this source and ignores any global sources
declared at the top level of the file. If the gem does not exist in this source,
it will not be installed.
Bundler will search for child dependencies of this gem by first looking in the
source selected for the parent, but if they are not found there, it will fall
back on global sources using the ordering described in [SOURCE PRIORITY][].
Selecting a specific source repository this way also suppresses the ambiguous
gem warning described above in
[GLOBAL SOURCES (#source)](#GLOBAL-SOURCES).
Using the `:source` option for an individual gem will also make that source
available as a possible global source for any other gems which do not specify
explicit sources. Thus, when adding gems with explicit sources, it is
recommended that you also ensure all other gems in the Gemfile are using
explicit sources.
### GIT
If necessary, you can specify that a gem is located at a particular
git repository using the `:git` parameter. The repository can be accessed via
several protocols:
* `HTTP(S)`:
gem "rails", :git => "https://github.com/rails/rails.git"
* `SSH`:
gem "rails", :git => "git@github.com:rails/rails.git"
* `git`:
gem "rails", :git => "git://github.com/rails/rails.git"
If using SSH, the user that you use to run `bundle install` `MUST` have the
appropriate keys available in their `$HOME/.ssh`.
`NOTE`: `http://` and `git://` URLs should be avoided if at all possible. These
protocols are unauthenticated, so a man-in-the-middle attacker can deliver
malicious code and compromise your system. HTTPS and SSH are strongly
preferred.
The `group`, `platforms`, and `require` options are available and behave
exactly the same as they would for a normal gem.
A git repository `SHOULD` have at least one file, at the root of the
directory containing the gem, with the extension `.gemspec`. This file
`MUST` contain a valid gem specification, as expected by the `gem build`
command.
If a git repository does not have a `.gemspec`, bundler will attempt to
create one, but it will not contain any dependencies, executables, or
C extension compilation instructions. As a result, it may fail to properly
integrate into your application.
If a git repository does have a `.gemspec` for the gem you attached it
to, a version specifier, if provided, means that the git repository is
only valid if the `.gemspec` specifies a version matching the version
specifier. If not, bundler will print a warning.
gem "rails", "2.3.8", :git => "https://github.com/rails/rails.git"
# bundle install will fail, because the .gemspec in the rails
# repository's master branch specifies version 3.0.0
If a git repository does `not` have a `.gemspec` for the gem you attached
it to, a version specifier `MUST` be provided. Bundler will use this
version in the simple `.gemspec` it creates.
Git repositories support a number of additional options.
* `branch`, `tag`, and `ref`:
You `MUST` only specify at most one of these options. The default
is `:branch => "master"`. For example:
gem "rails", :git => "https://github.com/rails/rails.git", :branch => "5-0-stable"
gem "rails", :git => "https://github.com/rails/rails.git", :tag => "v5.0.0"
gem "rails", :git => "https://github.com/rails/rails.git", :ref => "4aded"
* `submodules`:
For reference, a [git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules)
lets you have another git repository within a subfolder of your repository.
Specify `:submodules => true` to cause bundler to expand any
submodules included in the git repository
If a git repository contains multiple `.gemspecs`, each `.gemspec`
represents a gem located at the same place in the file system as
the `.gemspec`.
|~rails [git root]
| |-rails.gemspec [rails gem located here]
|~actionpack
| |-actionpack.gemspec [actionpack gem located here]
|~activesupport
| |-activesupport.gemspec [activesupport gem located here]
|...
To install a gem located in a git repository, bundler changes to
the directory containing the gemspec, runs `gem build name.gemspec`
and then installs the resulting gem. The `gem build` command,
which comes standard with Rubygems, evaluates the `.gemspec` in
the context of the directory in which it is located.
### GIT SOURCE
A custom git source can be defined via the `git_source` method. Provide the source's name
as an argument, and a block which receives a single argument and interpolates it into a
string to return the full repo address:
git_source(:stash){ |repo_name| "https://stash.corp.acme.pl/#{repo_name}.git" }
gem 'rails', :stash => 'forks/rails'
In addition, if you wish to choose a specific branch:
gem "rails", :stash => "forks/rails", :branch => "branch_name"
### GITHUB
`NOTE`: This shorthand should be avoided until Bundler 2.0, since it
currently expands to an insecure `git://` URL. This allows a
man-in-the-middle attacker to compromise your system.
If the git repository you want to use is hosted on GitHub and is public, you can use the
:github shorthand to specify the github username and repository name (without the
trailing ".git"), separated by a slash. If both the username and repository name are the
same, you can omit one.
gem "rails", :github => "rails/rails"
gem "rails", :github => "rails"
Are both equivalent to
gem "rails", :git => "git://github.com/rails/rails.git"
Since the `github` method is a specialization of `git_source`, it accepts a `:branch` named argument.
You can also directly pass a pull request URL:
gem "rails", :github => "https://github.com/rails/rails/pull/43753"
Which is equivalent to:
gem "rails", :github => "rails/rails", branch: "refs/pull/43753/head"
### GIST
If the git repository you want to use is hosted as a Github Gist and is public, you can use
the :gist shorthand to specify the gist identifier (without the trailing ".git").
gem "the_hatch", :gist => "4815162342"
Is equivalent to:
gem "the_hatch", :git => "https://gist.github.com/4815162342.git"
Since the `gist` method is a specialization of `git_source`, it accepts a `:branch` named argument.
### BITBUCKET
If the git repository you want to use is hosted on Bitbucket and is public, you can use the
:bitbucket shorthand to specify the bitbucket username and repository name (without the
trailing ".git"), separated by a slash. If both the username and repository name are the
same, you can omit one.
gem "rails", :bitbucket => "rails/rails"
gem "rails", :bitbucket => "rails"
Are both equivalent to
gem "rails", :git => "https://rails@bitbucket.org/rails/rails.git"
Since the `bitbucket` method is a specialization of `git_source`, it accepts a `:branch` named argument.
### PATH
You can specify that a gem is located in a particular location
on the file system. Relative paths are resolved relative to the
directory containing the `Gemfile`.
Similar to the semantics of the `:git` option, the `:path`
option requires that the directory in question either contains
a `.gemspec` for the gem, or that you specify an explicit
version that bundler should use.
Unlike `:git`, bundler does not compile C extensions for
gems specified as paths.
gem "rails", :path => "vendor/rails"
If you would like to use multiple local gems directly from the filesystem, you can set a global `path` option to the path containing the gem's files. This will automatically load gemspec files from subdirectories.
path 'components' do
gem 'admin_ui'
gem 'public_ui'
end
## BLOCK FORM OF SOURCE, GIT, PATH, GROUP and PLATFORMS
The `:source`, `:git`, `:path`, `:group`, and `:platforms` options may be
applied to a group of gems by using block form.
source "https://gems.example.com" do
gem "some_internal_gem"
gem "another_internal_gem"
end
git "https://github.com/rails/rails.git" do
gem "activesupport"
gem "actionpack"
end
platforms :ruby do
gem "ruby-debug"
gem "sqlite3"
end
group :development, :optional => true do
gem "wirble"
gem "faker"
end
In the case of the group block form the :optional option can be given
to prevent a group from being installed unless listed in the `--with`
option given to the `bundle install` command.
In the case of the `git` block form, the `:ref`, `:branch`, `:tag`,
and `:submodules` options may be passed to the `git` method, and
all gems in the block will inherit those options.
The presence of a `source` block in a Gemfile also makes that source
available as a possible global source for any other gems which do not specify
explicit sources. Thus, when defining source blocks, it is
recommended that you also ensure all other gems in the Gemfile are using
explicit sources, either via source blocks or `:source` directives on
individual gems.
## INSTALL_IF
The `install_if` method allows gems to be installed based on a proc or lambda.
This is especially useful for optional gems that can only be used if certain
software is installed or some other conditions are met.
install_if -> { RUBY_PLATFORM =~ /darwin/ } do
gem "pasteboard"
end
## GEMSPEC
The [`.gemspec`](http://guides.rubygems.org/specification-reference/) file is where
you provide metadata about your gem to Rubygems. Some required Gemspec
attributes include the name, description, and homepage of your gem. This is
also where you specify the dependencies your gem needs to run.
If you wish to use Bundler to help install dependencies for a gem while it is
being developed, use the `gemspec` method to pull in the dependencies listed in
the `.gemspec` file.
The `gemspec` method adds any runtime dependencies as gem requirements in the
default group. It also adds development dependencies as gem requirements in the
`development` group. Finally, it adds a gem requirement on your project (`:path
=> '.'`). In conjunction with `Bundler.setup`, this allows you to require project
files in your test code as you would if the project were installed as a gem; you
need not manipulate the load path manually or require project files via relative
paths.
The `gemspec` method supports optional `:path`, `:glob`, `:name`, and `:development_group`
options, which control where bundler looks for the `.gemspec`, the glob it uses to look
for the gemspec (defaults to: "{,*,*/*}.gemspec"), what named `.gemspec` it uses
(if more than one is present), and which group development dependencies are included in.
When a `gemspec` dependency encounters version conflicts during resolution, the
local version under development will always be selected -- even if there are
remote versions that better match other requirements for the `gemspec` gem.
## SOURCE PRIORITY
When attempting to locate a gem to satisfy a gem requirement,
bundler uses the following priority order:
1. The source explicitly attached to the gem (using `:source`, `:path`, or
`:git`)
2. For implicit gems (dependencies of explicit gems), any source, git, or path
repository declared on the parent. This results in bundler prioritizing the
ActiveSupport gem from the Rails git repository over ones from
`rubygems.org`
3. The sources specified via global `source` lines, searching each source in
your `Gemfile` from last added to first added.

.SH "NAME"
\fBGemfile\fR \- A format for describing gem dependencies for Ruby programs
.
.SH "SYNOPSIS"
A \fBGemfile\fR describes the gem dependencies required to execute associated Ruby code\.
.

Place the \fBGemfile\fR in the root of the directory containing the associated code\. For instance, in a Rails application, place the \fBGemfile\fR in the same directory as the \fBRakefile\fR\.
.
.SH "SYNTAX"
A \fBGemfile\fR is evaluated as Ruby code, in a context which makes available a number of methods used to describe the gem requirements\.

It is possible, but not recommended as of Bundler 1\.7, to add multiple global \fBsource\fR lines\. Each of these \fBsource\fRs \fBMUST\fR be a valid Rubygems repository\.
.
.P
Sources are checked for gems following the heuristics described in \fISOURCE PRIORITY\fR\. If a gem is found in more than one global source, Bundler will print a warning after installing the gem indicating which source was used, and listing the other sources where the gem is available\. A specific source can be selected for gems that need to use a non\-standard repository, suppressing this warning, by using the \fI\fB:source\fR option\fR or a \fI\fBsource\fR block\fR\.
.
.SS "CREDENTIALS"
Some gem sources require a username and password\. Use bundle config(1) \fIbundle\-config\.1\.html\fR to set the username and password for any of the sources that need it\. The command must be run once on each computer that will install the Gemfile, but this keeps the credentials from being stored in plain text in version control\.

Also, calling \fBBundler\.setup\fR with no parameters, or calling \fBrequire "bundler/setup"\fR will setup all groups except for the ones you excluded via \fB\-\-without\fR (since they are not available)\.
.
.P
Note that on \fBbundle install\fR, bundler downloads and evaluates all gems, in order to create a single canonical list of all of the required gems and their dependencies\. This means that you cannot list different versions of the same gems in different groups\. For more details, see Understanding Bundler \fIhttps://bundler\.io/rationale\.html\fR\.
.
.SS "PLATFORMS"
If a gem should only be used in a particular platform or set of platforms, you can specify them\. Platforms are essentially identical to groups, except that you do not need to use the \fB\-\-without\fR install\-time flag to exclude groups of gems for other platforms\.
.
.P
There are a number of \fBGemfile\fR platforms:
.

\fBruby\fR
C Ruby (MRI), Rubinius or TruffleRuby, but \fBNOT\fR Windows

.SS "SOURCE"
You can select an alternate Rubygems repository for a gem using the \':source\' option\.
.
.IP "" 4
.
.nf
gem "some_internal_gem", :source => "https://gems\.example\.com"
.
.fi
.
.IP "" 0
.
.P
This forces the gem to be loaded from this source and ignores any global sources declared at the top level of the file\. If the gem does not exist in this source, it will not be installed\.
.
.P
Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on global sources using the ordering described in \fISOURCE PRIORITY\fR\.
.
.P
Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in \fIGLOBAL SOURCES (#source)\fR\.
.
.P
Using the \fB:source\fR option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources\.
.
.SS "GIT"
If necessary, you can specify that a gem is located at a particular git repository using the \fB:git\fR parameter\. The repository can be accessed via several protocols:
.
.TP
\fBHTTP(S)\fR
gem "rails", :git => "https://github\.com/rails/rails\.git"

If using SSH, the user that you use to run \fBbundle install\fR \fBMUST\fR have the appropriate keys available in their \fB$HOME/\.ssh\fR\.
.
.P
\fBNOTE\fR: \fBhttp://\fR and \fBgit://\fR URLs should be avoided if at all possible\. These protocols are unauthenticated, so a man\-in\-the\-middle attacker can deliver malicious code and compromise your system\. HTTPS and SSH are strongly preferred\.
.
.P
The \fBgroup\fR, \fBplatforms\fR, and \fBrequire\fR options are available and behave exactly the same as they would for a normal gem\.
.
.P
A git repository \fBSHOULD\fR have at least one file, at the root of the directory containing the gem, with the extension \fB\.gemspec\fR\. This file \fBMUST\fR contain a valid gem specification, as expected by the \fBgem build\fR command\.
.
.P
If a git repository does not have a \fB\.gemspec\fR, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions\. As a result, it may fail to properly integrate into your application\.
.
.P
If a git repository does have a \fB\.gemspec\fR for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the \fB\.gemspec\fR specifies a version matching the version specifier\. If not, bundler will print a warning\.

Git repositories support a number of additional options\.
.
.TP
\fBbranch\fR, \fBtag\fR, and \fBref\fR
You \fBMUST\fR only specify at most one of these options\. The default is \fB:branch => "master"\fR\. For example:

.
.TP
\fBsubmodules\fR
For reference, a git submodule \fIhttps://git\-scm\.com/book/en/v2/Git\-Tools\-Submodules\fR lets you have another git repository within a subfolder of your repository\. Specify \fB:submodules => true\fR to cause bundler to expand any submodules included in the git repository
.

To install a gem located in a git repository, bundler changes to the directory containing the gemspec, runs \fBgem build name\.gemspec\fR and then installs the resulting gem\. The \fBgem build\fR command, which comes standard with Rubygems, evaluates the \fB\.gemspec\fR in the context of the directory in which it is located\.
.
.SS "GIT SOURCE"
A custom git source can be defined via the \fBgit_source\fR method\. Provide the source\'s name as an argument, and a block which receives a single argument and interpolates it into a string to return the full repo address:

If the git repository you want to use is hosted on GitHub and is public, you can use the :github shorthand to specify the github username and repository name (without the trailing "\.git"), separated by a slash\. If both the username and repository name are the same, you can omit one\.

Similar to the semantics of the \fB:git\fR option, the \fB:path\fR option requires that the directory in question either contains a \fB\.gemspec\fR for the gem, or that you specify an explicit version that bundler should use\.

In the case of the \fBgit\fR block form, the \fB:ref\fR, \fB:branch\fR, \fB:tag\fR, and \fB:submodules\fR options may be passed to the \fBgit\fR method, and all gems in the block will inherit those options\.
.
.P
The presence of a \fBsource\fR block in a Gemfile also makes that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when defining source blocks, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources, either via source blocks or \fB:source\fR directives on individual gems\.
.
.SH "INSTALL_IF"
The \fBinstall_if\fR method allows gems to be installed based on a proc or lambda\. This is especially useful for optional gems that can only be used if certain software is installed or some other conditions are met\.

.SH "GEMSPEC"
The \fB\.gemspec\fR \fIhttp://guides\.rubygems\.org/specification\-reference/\fR file is where you provide metadata about your gem to Rubygems\. Some required Gemspec attributes include the name, description, and homepage of your gem\. This is also where you specify the dependencies your gem needs to run\.
.
.P
If you wish to use Bundler to help install dependencies for a gem while it is being developed, use the \fBgemspec\fR method to pull in the dependencies listed in the \fB\.gemspec\fR file\.
.
.P
The \fBgemspec\fR method adds any runtime dependencies as gem requirements in the default group\. It also adds development dependencies as gem requirements in the \fBdevelopment\fR group\. Finally, it adds a gem requirement on your project (\fB:path => \'\.\'\fR)\. In conjunction with \fBBundler\.setup\fR, this allows you to require project files in your test code as you would if the project were installed as a gem; you need not manipulate the load path manually or require project files via relative paths\.
.
.P
The \fBgemspec\fR method supports optional \fB:path\fR, \fB:glob\fR, \fB:name\fR, and \fB:development_group\fR options, which control where bundler looks for the \fB\.gemspec\fR, the glob it uses to look for the gemspec (defaults to: "{,\fI,\fR/*}\.gemspec"), what named \fB\.gemspec\fR it uses (if more than one is present), and which group development dependencies are included in\.
.
.P
When a \fBgemspec\fR dependency encounters version conflicts during resolution, the local version under development will always be selected \-\- even if there are remote versions that better match other requirements for the \fBgemspec\fR gem\.
.
.SH "SOURCE PRIORITY"
When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order:
.
.IP "1." 4
The source explicitly attached to the gem (using \fB:source\fR, \fB:path\fR, or \fB:git\fR)
.
.IP "2." 4
For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent\. This results in bundler prioritizing the ActiveSupport gem from the Rails git repository over ones from \fBrubygems\.org\fR
.
.IP "3." 4
The sources specified via global \fBsource\fR lines, searching each source in your \fBGemfile\fR from last added to first added\.

========================================================================
## SYNOPSIS
`bundle init` [--gemspec=FILE]
## DESCRIPTION
Init generates a default [`Gemfile(5)`][Gemfile(5)] in the current working directory. When
adding a [`Gemfile(5)`][Gemfile(5)] to a gem with a gemspec, the `--gemspec` option will
automatically add each dependency listed in the gemspec file to the newly
created [`Gemfile(5)`][Gemfile(5)].
## OPTIONS
* `--gemspec`:
Use the specified .gemspec to create the [`Gemfile(5)`][Gemfile(5)]
## FILES
Included in the default [`Gemfile(5)`][Gemfile(5)]
generated is the line `# frozen_string_literal: true`. This is a magic comment
supported for the first time in Ruby 2.3. The presence of this line
results in all string literals in the file being implicitly frozen.

=====================================================
## SYNOPSIS
`bundle config` [list|get|set|unset] [<name> [<value>]]
## DESCRIPTION
This command allows you to interact with Bundler's configuration system.
Bundler loads configuration settings in this order:
1. Local config (`<project_root>/.bundle/config` or `$BUNDLE_APP_CONFIG/config`)
2. Environmental variables (`ENV`)
3. Global config (`~/.bundle/config`)
4. Bundler default config
Executing `bundle config list` with will print a list of all bundler
configuration for the current bundle, and where that configuration
was set.
Executing `bundle config get <name>` will print the value of that configuration
setting, and where it was set.
Executing `bundle config set <name> <value>` will set that configuration to the
value specified for all bundles executed as the current user. The configuration
will be stored in `~/.bundle/config`. If <name> already is set, <name> will be
overridden and user will be warned.
Executing `bundle config set --global <name> <value>` works the same as above.
Executing `bundle config set --local <name> <value>` will set that configuration
in the directory for the local application. The configuration will be stored in
`<project_root>/.bundle/config`. If `BUNDLE_APP_CONFIG` is set, the configuration
will be stored in `$BUNDLE_APP_CONFIG/config`.
Executing `bundle config unset <name>` will delete the configuration in both
local and global sources.
Executing `bundle config unset --global <name>` will delete the configuration
only from the user configuration.
Executing `bundle config unset --local <name> <value>` will delete the
configuration only from the local application.
Executing bundle with the `BUNDLE_IGNORE_CONFIG` environment variable set will
cause it to ignore all configuration.
## REMEMBERING OPTIONS
Flags passed to `bundle install` or the Bundler runtime, such as `--path foo` or
`--without production`, are remembered between commands and saved to your local
application's configuration (normally, `./.bundle/config`).
However, this will be changed in bundler 3, so it's better not to rely on this
behavior. If these options must be remembered, it's better to set them using
`bundle config` (e.g., `bundle config set --local path foo`).
The options that can be configured are:
* `bin`:
Creates a directory (defaults to `~/bin`) and place any executables from the
gem there. These executables run in Bundler's context. If used, you might add
this directory to your environment's `PATH` variable. For instance, if the
`rails` gem comes with a `rails` executable, this flag will create a
`bin/rails` executable that ensures that all referred dependencies will be
resolved using the bundled gems.
* `deployment`:
In deployment mode, Bundler will 'roll-out' the bundle for
`production` use. Please check carefully if you want to have this option
enabled in `development` or `test` environments.
* `path`:
The location to install the specified gems to. This defaults to Rubygems'
setting. Bundler shares this location with Rubygems, `gem install ...` will
have gem installed there, too. Therefore, gems installed without a
`--path ...` setting will show up by calling `gem list`. Accordingly, gems
installed to other locations will not get listed.
* `without`:
A space-separated list of groups referencing gems to skip during installation.
* `with`:
A space-separated list of groups referencing gems to include during installation.
## BUILD OPTIONS
You can use `bundle config` to give Bundler the flags to pass to the gem
installer every time bundler tries to install a particular gem.
A very common example, the `mysql` gem, requires Snow Leopard users to
pass configuration flags to `gem install` to specify where to find the
`mysql_config` executable.
gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Since the specific location of that executable can change from machine
to machine, you can specify these flags on a per-machine basis.
bundle config set --global build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config
After running this command, every time bundler needs to install the
`mysql` gem, it will pass along the flags you specified.
## CONFIGURATION KEYS
Configuration keys in bundler have two forms: the canonical form and the
environment variable form.
For instance, passing the `--without` flag to [bundle install(1)](bundle-install.1.html)
prevents Bundler from installing certain groups specified in the Gemfile(5). Bundler
persists this value in `app/.bundle/config` so that calls to `Bundler.setup`
do not try to find gems from the `Gemfile` that you didn't install. Additionally,
subsequent calls to [bundle install(1)](bundle-install.1.html) remember this setting
and skip those groups.
The canonical form of this configuration is `"without"`. To convert the canonical
form to the environment variable form, capitalize it, and prepend `BUNDLE_`. The
environment variable form of `"without"` is `BUNDLE_WITHOUT`.
Any periods in the configuration keys must be replaced with two underscores when
setting it via environment variables. The configuration key `local.rack` becomes
the environment variable `BUNDLE_LOCAL__RACK`.
## LIST OF AVAILABLE KEYS
The following is a list of all configuration keys and their purpose. You can
learn more about their operation in [bundle install(1)](bundle-install.1.html).
* `allow_deployment_source_credential_changes` (`BUNDLE_ALLOW_DEPLOYMENT_SOURCE_CREDENTIAL_CHANGES`):

* `bin` (`BUNDLE_BIN`):
Install executables from gems in the bundle to the specified directory.
Defaults to `false`.
* `cache_all` (`BUNDLE_CACHE_ALL`):

configured on bundler 1 and bundler 2, but will be the default on bundler 3.
* `cache_all_platforms` (`BUNDLE_CACHE_ALL_PLATFORMS`):
Cache gems for all platforms.
* `cache_path` (`BUNDLE_CACHE_PATH`):
The directory that bundler will place cached gems in when running
<code>bundle package</code>, and that bundler will look in when installing gems.
Defaults to `vendor/cache`.
* `clean` (`BUNDLE_CLEAN`):
Whether Bundler should run `bundle clean` automatically after
`bundle install`.

Allow installing gems even if they do not match the checksum provided by
RubyGems.
* `disable_exec_load` (`BUNDLE_DISABLE_EXEC_LOAD`):
Stop Bundler from using `load` to launch an executable in-process in
`bundle exec`.
* `disable_local_branch_check` (`BUNDLE_DISABLE_LOCAL_BRANCH_CHECK`):
Allow Bundler to use a local git override without a branch specified in the
Gemfile.
* `disable_local_revision_check` (`BUNDLE_DISABLE_LOCAL_REVISION_CHECK`):

* `disable_shared_gems` (`BUNDLE_DISABLE_SHARED_GEMS`):
Stop Bundler from accessing gems installed to RubyGems' normal location.
* `disable_version_check` (`BUNDLE_DISABLE_VERSION_CHECK`):
Stop Bundler from checking if a newer Bundler version is available on
rubygems.org.
* `force_ruby_platform` (`BUNDLE_FORCE_RUBY_PLATFORM`):
Ignore the current machine's platform and install only `ruby` platform gems.
As a result, gems with native extensions will be compiled from source.
* `frozen` (`BUNDLE_FROZEN`):
Disallow changes to the `Gemfile`. When the `Gemfile` is changed and the
lockfile has not been updated, running Bundler commands will be blocked.
Defaults to `true` when `--deployment` is used.
* `gem.github_username` (`BUNDLE_GEM__GITHUB_USERNAME`):

Sets the `--key` parameter for `gem push` when using the `rake release`
command with a private gemstash server.
* `gemfile` (`BUNDLE_GEMFILE`):
The name of the file that bundler should use as the `Gemfile`. This location
of this file also sets the root of the project, which is used to resolve
relative paths in the `Gemfile`, among other things. By default, bundler
will search up from the current working directory until it finds a
`Gemfile`.
* `global_gem_cache` (`BUNDLE_GLOBAL_GEM_CACHE`):
Whether Bundler should cache all gems globally, rather than locally to the
installing Ruby installation.

Whether Bundler should leave outdated gems unpruned when caching.
* `path` (`BUNDLE_PATH`):
The location on disk where all gems in your bundle will be located regardless
of `$GEM_HOME` or `$GEM_PATH` values. Bundle gems not found in this location
will be installed by `bundle install`. Defaults to `Gem.dir`. When --deployment
is used, defaults to vendor/bundle.
* `path.system` (`BUNDLE_PATH__SYSTEM`):
Whether Bundler will install gems into the default system path (`Gem.dir`).

The location where RubyGems installs binstubs. Defaults to `Gem.bindir`.
* `timeout` (`BUNDLE_TIMEOUT`):
The seconds allowed before timing out for network requests. Defaults to `10`.
* `update_requires_all_flag` (`BUNDLE_UPDATE_REQUIRES_ALL_FLAG`):
Require passing `--all` to `bundle update` when everything should be updated,
and disallow passing no options to `bundle update`.
* `user_agent` (`BUNDLE_USER_AGENT`):
The custom user agent fragment Bundler includes in API requests.
* `with` (`BUNDLE_WITH`):
A `:`-separated list of groups whose gems bundler should install.
* `without` (`BUNDLE_WITHOUT`):
A `:`-separated list of groups whose gems bundler should not install.
In general, you should set these settings per-application by using the applicable
flag to the [bundle install(1)](bundle-install.1.html) or [bundle package(1)](bundle-package.1.html) command.
You can set them globally either via environment variables or `bundle config`,
whichever is preferable for your setup. If you use both, environment variables
will take preference over global settings.
## LOCAL GIT REPOS
Bundler also allows you to work against a git repository locally
instead of using the remote version. This can be achieved by setting
up a local override:
bundle config set --local local.GEM_NAME /path/to/local/git/repository
For example, in order to use a local Rack repository, a developer could call:
bundle config set --local local.rack ~/Work/git/rack
Now instead of checking out the remote git repository, the local
override will be used. Similar to a path source, every time the local
git repository change, changes will be automatically picked up by
Bundler. This means a commit in the local git repo will update the
revision in the `Gemfile.lock` to the local git repo revision. This
requires the same attention as git submodules. Before pushing to
the remote, you need to ensure the local override was pushed, otherwise
you may point to a commit that only exists in your local machine.
You'll also need to CGI escape your usernames and passwords as well.
Bundler does many checks to ensure a developer won't work with
invalid references. Particularly, we force a developer to specify
a branch in the `Gemfile` in order to use this feature. If the branch
specified in the `Gemfile` and the current branch in the local git
repository do not match, Bundler will abort. This ensures that
a developer is always working against the correct branches, and prevents
accidental locking to a different branch.
Finally, Bundler also ensures that the current revision in the
`Gemfile.lock` exists in the local git repository. By doing this, Bundler
forces you to fetch the latest changes in the remotes.
## MIRRORS OF GEM SOURCES
Bundler supports overriding gem sources with mirrors. This allows you to
configure rubygems.org as the gem source in your Gemfile while still using your
mirror to fetch gems.
bundle config set --global mirror.SOURCE_URL MIRROR_URL
For example, to use a mirror of rubygems.org hosted at rubygems-mirror.org:
bundle config set --global mirror.http://rubygems.org http://rubygems-mirror.org
Each mirror also provides a fallback timeout setting. If the mirror does not
respond within the fallback timeout, Bundler will try to use the original
server instead of the mirror.
bundle config set --global mirror.SOURCE_URL.fallback_timeout TIMEOUT
For example, to fall back to rubygems.org after 3 seconds:
bundle config set --global mirror.https://rubygems.org.fallback_timeout 3
The default fallback timeout is 0.1 seconds, but the setting can currently
only accept whole seconds (for example, 1, 15, or 30).
## CREDENTIALS FOR GEM SOURCES
Bundler allows you to configure credentials for any gem source, which allows
you to avoid putting secrets into your Gemfile.
bundle config set --global SOURCE_HOSTNAME USERNAME:PASSWORD
For example, to save the credentials of user `claudette` for the gem source at
`gems.longerous.com`, you would run:
bundle config set --global gems.longerous.com claudette:s00pers3krit
Or you can set the credentials as an environment variable like this:
export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit"
For gems with a git source with HTTP(S) URL you can specify credentials like so:
bundle config set --global https://github.com/rubygems/rubygems.git username:password
Or you can set the credentials as an environment variable like so:
export BUNDLE_GITHUB__COM=username:password
This is especially useful for private repositories on hosts such as Github,
where you can use personal OAuth tokens:
export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x-oauth-basic
Note that any configured credentials will be redacted by informative commands
such as `bundle config list` or `bundle config get`, unless you use the
`--parseable` flag. This is to avoid unintentionally leaking credentials when
copy-pasting bundler output.
Also note that to guarantee a sane mapping between valid environment variable
names and valid host names, bundler makes the following transformations:
* Any `-` characters in a host name are mapped to a triple dash (`___`) in the
corresponding environment variable.
* Any `.` characters in a host name are mapped to a double dash (`__`) in the
corresponding environment variable.
This means that if you have a gem server named `my.gem-host.com`, you'll need to
use the `BUNDLE_MY__GEM___HOST__COM` variable to configure credentials for it
through ENV.
## CONFIGURE BUNDLER DIRECTORIES
Bundler's home, config, cache and plugin directories are able to be configured
through environment variables. The default location for Bundler's home directory is
`~/.bundle`, which all directories inherit from by default. The following
outlines the available environment variables and their default values
BUNDLE_USER_HOME : $HOME/.bundle
BUNDLE_USER_CACHE : $BUNDLE_USER_HOME/cache
BUNDLE_USER_CONFIG : $BUNDLE_USER_HOME/config
BUNDLE_USER_PLUGIN : $BUNDLE_USER_HOME/plugin

## SYNOPSIS
`bundle check` [--dry-run]
[--gemfile=FILE]
[--path=PATH]
## DESCRIPTION
`check` searches the local machine for each of the gems requested in the
Gemfile. If all gems are found, Bundler prints a success message and exits with
a status of 0.
If not, the first missing gem is listed and Bundler exits status 1.
## OPTIONS
* `--dry-run`:
Locks the [`Gemfile(5)`][Gemfile(5)] before running the command.
* `--gemfile`:
Use the specified gemfile instead of the [`Gemfile(5)`][Gemfile(5)].
* `--path`:
Specify a different path than the system default (`$BUNDLE_PATH` or `$GEM_HOME`).
Bundler will remember this value for future installs on this machine.

\fBbundle config\fR [list|get|set|unset] [\fIname\fR [\fIvalue\fR]]
.
.SH "DESCRIPTION"
This command allows you to interact with Bundler\'s configuration system\.
.
.P
Bundler loads configuration settings in this order:
.
.IP "1." 4
Local config (\fB<project_root>/\.bundle/config\fR or \fB$BUNDLE_APP_CONFIG/config\fR)
.
.IP "2." 4
Environmental variables (\fBENV\fR)
.
.IP "3." 4
Global config (\fB~/\.bundle/config\fR)
.
.IP "4." 4
Bundler default config
.
.IP "" 0
.
.P
Executing \fBbundle config list\fR with will print a list of all bundler configuration for the current bundle, and where that configuration was set\.
.
.P
Executing \fBbundle config get <name>\fR will print the value of that configuration setting, and where it was set\.
.
.P
Executing \fBbundle config set <name> <value>\fR will set that configuration to the value specified for all bundles executed as the current user\. The configuration will be stored in \fB~/\.bundle/config\fR\. If \fIname\fR already is set, \fIname\fR will be overridden and user will be warned\.
.
.P
Executing \fBbundle config set \-\-global <name> <value>\fR works the same as above\.
.
.P
Executing \fBbundle config set \-\-local <name> <value>\fR will set that configuration in the directory for the local application\. The configuration will be stored in \fB<project_root>/\.bundle/config\fR\. If \fBBUNDLE_APP_CONFIG\fR is set, the configuration will be stored in \fB$BUNDLE_APP_CONFIG/config\fR\.
.
.P
Executing \fBbundle config unset <name>\fR will delete the configuration in both local and global sources\.
.
.P
Executing \fBbundle config unset \-\-global <name>\fR will delete the configuration only from the user configuration\.
.
.P
Executing \fBbundle config unset \-\-local <name> <value>\fR will delete the configuration only from the local application\.
.
.P
Executing bundle with the \fBBUNDLE_IGNORE_CONFIG\fR environment variable set will cause it to ignore all configuration\.
.
.SH "REMEMBERING OPTIONS"
Flags passed to \fBbundle install\fR or the Bundler runtime, such as \fB\-\-path foo\fR or \fB\-\-without production\fR, are remembered between commands and saved to your local application\'s configuration (normally, \fB\./\.bundle/config\fR)\.
.
.P
However, this will be changed in bundler 3, so it\'s better not to rely on this behavior\. If these options must be remembered, it\'s better to set them using \fBbundle config\fR (e\.g\., \fBbundle config set \-\-local path foo\fR)\.
.
.P
The options that can be configured are:
.
.TP
\fBbin\fR
Creates a directory (defaults to \fB~/bin\fR) and place any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\.
.
.TP
\fBdeployment\fR
In deployment mode, Bundler will \'roll\-out\' the bundle for \fBproduction\fR use\. Please check carefully if you want to have this option enabled in \fBdevelopment\fR or \fBtest\fR environments\.
.
.TP
\fBpath\fR
The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\.
.
.TP
\fBwithout\fR
A space\-separated list of groups referencing gems to skip during installation\.
.
.TP
\fBwith\fR
A space\-separated list of groups referencing gems to include during installation\.
.
.SH "BUILD OPTIONS"
You can use \fBbundle config\fR to give Bundler the flags to pass to the gem installer every time bundler tries to install a particular gem\.
.
.P
A very common example, the \fBmysql\fR gem, requires Snow Leopard users to pass configuration flags to \fBgem install\fR to specify where to find the \fBmysql_config\fR executable\.
.
.IP "" 4
.
.nf
gem install mysql \-\- \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config
.
.fi
.
.IP "" 0
.
.P
Since the specific location of that executable can change from machine to machine, you can specify these flags on a per\-machine basis\.
.
.IP "" 4
.
.nf
bundle config set \-\-global build\.mysql \-\-with\-mysql\-config=/usr/local/mysql/bin/mysql_config
.
.fi
.
.IP "" 0
.
.P
After running this command, every time bundler needs to install the \fBmysql\fR gem, it will pass along the flags you specified\.
.
.SH "CONFIGURATION KEYS"
Configuration keys in bundler have two forms: the canonical form and the environment variable form\.
.
.P
For instance, passing the \fB\-\-without\fR flag to bundle install(1) \fIbundle\-install\.1\.html\fR prevents Bundler from installing certain groups specified in the Gemfile(5)\. Bundler persists this value in \fBapp/\.bundle/config\fR so that calls to \fBBundler\.setup\fR do not try to find gems from the \fBGemfile\fR that you didn\'t install\. Additionally, subsequent calls to bundle install(1) \fIbundle\-install\.1\.html\fR remember this setting and skip those groups\.
.
.P
The canonical form of this configuration is \fB"without"\fR\. To convert the canonical form to the environment variable form, capitalize it, and prepend \fBBUNDLE_\fR\. The environment variable form of \fB"without"\fR is \fBBUNDLE_WITHOUT\fR\.
.
.P
Any periods in the configuration keys must be replaced with two underscores when setting it via environment variables\. The configuration key \fBlocal\.rack\fR becomes the environment variable \fBBUNDLE_LOCAL__RACK\fR\.
.
.SH "LIST OF AVAILABLE KEYS"
The following is a list of all configuration keys and their purpose\. You can learn more about their operation in bundle install(1) \fIbundle\-install\.1\.html\fR\.

.P
In general, you should set these settings per\-application by using the applicable flag to the bundle install(1) \fIbundle\-install\.1\.html\fR or bundle package(1) \fIbundle\-package\.1\.html\fR command\.
.
.P
You can set them globally either via environment variables or \fBbundle config\fR, whichever is preferable for your setup\. If you use both, environment variables will take preference over global settings\.
.
.SH "LOCAL GIT REPOS"
Bundler also allows you to work against a git repository locally instead of using the remote version\. This can be achieved by setting up a local override:
.
.IP "" 4
.
.nf
bundle config set \-\-local local\.GEM_NAME /path/to/local/git/repository
.
.fi
.
.IP "" 0
.
.P
For example, in order to use a local Rack repository, a developer could call:
.
.IP "" 4
.
.nf
bundle config set \-\-local local\.rack ~/Work/git/rack
.
.fi
.
.IP "" 0
.
.P
Now instead of checking out the remote git repository, the local override will be used\. Similar to a path source, every time the local git repository change, changes will be automatically picked up by Bundler\. This means a commit in the local git repo will update the revision in the \fBGemfile\.lock\fR to the local git repo revision\. This requires the same attention as git submodules\. Before pushing to the remote, you need to ensure the local override was pushed, otherwise you may point to a commit that only exists in your local machine\. You\'ll also need to CGI escape your usernames and passwords as well\.
.
.P
Bundler does many checks to ensure a developer won\'t work with invalid references\. Particularly, we force a developer to specify a branch in the \fBGemfile\fR in order to use this feature\. If the branch specified in the \fBGemfile\fR and the current branch in the local git repository do not match, Bundler will abort\. This ensures that a developer is always working against the correct branches, and prevents accidental locking to a different branch\.
.
.P
Finally, Bundler also ensures that the current revision in the \fBGemfile\.lock\fR exists in the local git repository\. By doing this, Bundler forces you to fetch the latest changes in the remotes\.
.
.SH "MIRRORS OF GEM SOURCES"
Bundler supports overriding gem sources with mirrors\. This allows you to configure rubygems\.org as the gem source in your Gemfile while still using your mirror to fetch gems\.
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.SOURCE_URL MIRROR_URL
.
.fi
.
.IP "" 0
.
.P
For example, to use a mirror of rubygems\.org hosted at rubygems\-mirror\.org:
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.http://rubygems\.org http://rubygems\-mirror\.org
.
.fi
.
.IP "" 0
.
.P
Each mirror also provides a fallback timeout setting\. If the mirror does not respond within the fallback timeout, Bundler will try to use the original server instead of the mirror\.
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.SOURCE_URL\.fallback_timeout TIMEOUT
.
.fi
.
.IP "" 0

For example, to fall back to rubygems\.org after 3 seconds:
.
.IP "" 4
.
.nf
bundle config set \-\-global mirror\.https://rubygems\.org\.fallback_timeout 3
.
.fi
.
.IP "" 0
.
.P
The default fallback timeout is 0\.1 seconds, but the setting can currently only accept whole seconds (for example, 1, 15, or 30)\.
.
.SH "CREDENTIALS FOR GEM SOURCES"
Bundler allows you to configure credentials for any gem source, which allows you to avoid putting secrets into your Gemfile\.
.
.IP "" 4
.
.nf
bundle config set \-\-global SOURCE_HOSTNAME USERNAME:PASSWORD
.
.fi
.
.IP "" 0
.
.P
For example, to save the credentials of user \fBclaudette\fR for the gem source at \fBgems\.longerous\.com\fR, you would run:
.
.IP "" 4
.
.nf
bundle config set \-\-global gems\.longerous\.com claudette:s00pers3krit
.
.fi
.
.IP "" 0
.
.P
Or you can set the credentials as an environment variable like this:
.
.IP "" 4
.
.nf
export BUNDLE_GEMS__LONGEROUS__COM="claudette:s00pers3krit"
.
.fi
.
.IP "" 0
.
.P
For gems with a git source with HTTP(S) URL you can specify credentials like so:
.
.IP "" 4
.
.nf
bundle config set \-\-global https://github\.com/rubygems/rubygems\.git username:password
.
.fi
.
.IP "" 0
.
.P
Or you can set the credentials as an environment variable like so:
.
.IP "" 4
.
.nf
export BUNDLE_GITHUB__COM=username:password
.
.fi
.
.IP "" 0
.
.P
This is especially useful for private repositories on hosts such as Github, where you can use personal OAuth tokens:
.
.IP "" 4
.
.nf
export BUNDLE_GITHUB__COM=abcd0123generatedtoken:x\-oauth\-basic
.
.fi
.
.IP "" 0
.
.P
Note that any configured credentials will be redacted by informative commands such as \fBbundle config list\fR or \fBbundle config get\fR, unless you use the \fB\-\-parseable\fR flag\. This is to avoid unintentionally leaking credentials when copy\-pasting bundler output\.
.
.P
Also note that to guarantee a sane mapping between valid environment variable names and valid host names, bundler makes the following transformations:
.
.IP "\(bu" 4
Any \fB\-\fR characters in a host name are mapped to a triple dash (\fB___\fR) in the corresponding environment variable\.
.
.IP "\(bu" 4
Any \fB\.\fR characters in a host name are mapped to a double dash (\fB__\fR) in the corresponding environment variable\.
.
.IP "" 0
.
.P
This means that if you have a gem server named \fBmy\.gem\-host\.com\fR, you\'ll need to use the \fBBUNDLE_MY__GEM___HOST__COM\fR variable to configure credentials for it through ENV\.
.
.SH "CONFIGURE BUNDLER DIRECTORIES"
Bundler\'s home, config, cache and plugin directories are able to be configured through environment variables\.

## SYNOPSIS
`bundle clean` [--dry-run] [--force]
## DESCRIPTION
This command will remove all unused gems in your bundler directory. This is
useful when you have made many changes to your gem dependencies.
## OPTIONS
* `--dry-run`:
Print the changes, but do not clean the unused gems.
* `--force`:
Force a clean even if `--path` is not set.

## DESCRIPTION
Install the gems specified in your Gemfile(5). If this is the first
time you run bundle install (and a `Gemfile.lock` does not exist),
Bundler will fetch all remote sources, resolve dependencies and
install all needed gems.
If a `Gemfile.lock` does exist, and you have not updated your Gemfile(5),
Bundler will fetch all remote sources, but use the dependencies
specified in the `Gemfile.lock` instead of resolving dependencies.
If a `Gemfile.lock` does exist, and you have updated your Gemfile(5),
Bundler will use the dependencies in the `Gemfile.lock` for all gems
that you did not update, but will re-resolve the dependencies of
gems that you did update. You can find more information about this
update process below under [CONSERVATIVE UPDATING][].
## OPTIONS
The `--clean`, `--deployment`, `--frozen`, `--no-prune`, `--path`, `--shebang`,
`--system`, `--without` and `--with` options are deprecated because they only
make sense if they are applied to every subsequent `bundle install` run
automatically and that requires `bundler` to silently remember them. Since
`bundler` will no longer remember CLI flags in future versions, `bundle config`
(see bundle-config(1)) should be used to apply them permanently.
* `--binstubs[=<directory>]`:
Binstubs are scripts that wrap around executables. Bundler creates a small Ruby
file (a binstub) that loads Bundler, runs the command, and puts it in `bin/`.
This lets you link the binstub inside of an application to the exact gem
version the application needs.
Creates a directory (defaults to `~/bin`) and places any executables from the
gem there. These executables run in Bundler's context. If used, you might add
this directory to your environment's `PATH` variable. For instance, if the
`rails` gem comes with a `rails` executable, this flag will create a
`bin/rails` executable that ensures that all referred dependencies will be
resolved using the bundled gems.
* `--clean`:
On finishing the installation Bundler is going to remove any gems not present
in the current Gemfile(5). Don't worry, gems currently in use will not be
removed.
This option is deprecated in favor of the `clean` setting.
* `--deployment`:
In [deployment mode][DEPLOYMENT MODE], Bundler will 'roll-out' the bundle for
production or CI use. Please check carefully if you want to have this option
enabled in your development environment.
This option is deprecated in favor of the `deployment` setting.
* `--redownload`:
Force download every gem, even if the required versions are already available
locally.
* `--frozen`:
Do not allow the Gemfile.lock to be updated after this install. Exits
non-zero if there are going to be changes to the Gemfile.lock.
This option is deprecated in favor of the `frozen` setting.
* `--full-index`:
Bundler will not call Rubygems' API endpoint (default) but download and cache
a (currently big) index file of all gems. Performance can be improved for
large bundles that seldom change by enabling this option.
* `--gemfile=<gemfile>`:
The location of the Gemfile(5) which Bundler should use. This defaults
to a Gemfile(5) in the current working directory. In general, Bundler
will assume that the location of the Gemfile(5) is also the project's
root and will try to find `Gemfile.lock` and `vendor/cache` relative
to this location.
* `--jobs=[<number>]`, `-j[<number>]`:
The maximum number of parallel download and install jobs. The default
is `1`.
* `--local`:
Do not attempt to connect to `rubygems.org`. Instead, Bundler will use the
gems already present in Rubygems' cache or in `vendor/cache`. Note that if an
appropriate platform-specific gem exists on `rubygems.org` it will not be
found.
* `--no-cache`:
Do not update the cache in `vendor/cache` with the newly bundled gems. This
does not remove any gems in the cache but keeps the newly bundled gems from
being cached during the install.
* `--no-prune`:
Don't remove stale gems from the cache when the installation finishes.
This option is deprecated in favor of the `no_prune` setting.
* `--path=<path>`:
The location to install the specified gems to. This defaults to Rubygems'
setting. Bundler shares this location with Rubygems, `gem install ...` will
have gem installed there, too. Therefore, gems installed without a
`--path ...` setting will show up by calling `gem list`. Accordingly, gems
installed to other locations will not get listed.
This option is deprecated in favor of the `path` setting.
* `--quiet`:
Do not print progress information to the standard output. Instead, Bundler
will exit using a status code (`$?`).
* `--retry=[<number>]`:
Retry failed network or git requests for <number> times.
* `--shebang=<ruby-executable>`:
Uses the specified ruby executable (usually `ruby`) to execute the scripts
created with `--binstubs`. In addition, if you use `--binstubs` together with
`--shebang jruby` these executables will be changed to execute `jruby`
instead.
This option is deprecated in favor of the `shebang` setting.
* `--standalone[=<list>]`:
Makes a bundle that can work without depending on Rubygems or Bundler at
runtime. A space separated list of groups to install has to be specified.
Bundler creates a directory named `bundle` and installs the bundle there. It
also generates a `bundle/bundler/setup.rb` file to replace Bundler's own setup
in the manner required. Using this option implicitly sets `path`, which is a
[remembered option][REMEMBERED OPTIONS].
* `--system`:
Installs the gems specified in the bundle to the system's Rubygems location.
This overrides any previous configuration of `--path`.
This option is deprecated in favor of the `system` setting.
* `--trust-policy=[<policy>]`:
Apply the Rubygems security policy <policy>, where policy is one of
`HighSecurity`, `MediumSecurity`, `LowSecurity`, `AlmostNoSecurity`, or
`NoSecurity`. For more details, please see the Rubygems signing documentation
linked below in [SEE ALSO][].
* `--with=<list>`:
A space-separated list of groups referencing gems to install. If an
optional group is given it is installed. If a group is given that is
in the remembered list of groups given to --without, it is removed
from that list.
This option is deprecated in favor of the `with` setting.
* `--without=<list>`:
A space-separated list of groups referencing gems to skip during installation.
If a group is given that is in the remembered list of groups given
to --with, it is removed from that list.
This option is deprecated in favor of the `without` setting.
## DEPLOYMENT MODE
Bundler's defaults are optimized for development. To switch to
defaults optimized for deployment and for CI, use the `--deployment`
flag. Do not activate deployment mode on development machines, as it
will cause an error when the Gemfile(5) is modified.
1. A `Gemfile.lock` is required.
To ensure that the same versions of the gems you developed with
and tested with are also used in deployments, a `Gemfile.lock`
is required.
This is mainly to ensure that you remember to check your
`Gemfile.lock` into version control.
2. The `Gemfile.lock` must be up to date
In development, you can modify your Gemfile(5) and re-run
`bundle install` to [conservatively update][CONSERVATIVE UPDATING]
your `Gemfile.lock` snapshot.
In deployment, your `Gemfile.lock` should be up-to-date with
changes made in your Gemfile(5).
3. Gems are installed to `vendor/bundle` not your default system location
In development, it's convenient to share the gems used in your
application with other applications and other scripts that run on
the system.
In deployment, isolation is a more important default. In addition,
the user deploying the application may not have permission to install
gems to the system, or the web server may not have permission to
read them.
As a result, `bundle install --deployment` installs gems to
the `vendor/bundle` directory in the application. This may be
overridden using the `--path` option.
## SUDO USAGE
By default, Bundler installs gems to the same location as `gem install`.
In some cases, that location may not be writable by your Unix user. In
that case, Bundler will stage everything in a temporary directory,
then ask you for your `sudo` password in order to copy the gems into
their system location.
From your perspective, this is identical to installing the gems
directly into the system.
You should never use `sudo bundle install`. This is because several
other steps in `bundle install` must be performed as the current user:
* Updating your `Gemfile.lock`
* Updating your `vendor/cache`, if necessary
* Checking out private git repositories using your user's SSH keys
Of these three, the first two could theoretically be performed by
`chown`ing the resulting files to `$SUDO_USER`. The third, however,
can only be performed by invoking the `git` command as
the current user. Therefore, git gems are downloaded and installed
into `~/.bundle` rather than $GEM_HOME or $BUNDLE_PATH.
As a result, you should run `bundle install` as the current user,
and Bundler will ask for your password if it is needed to put the
gems into their final location.
## INSTALLING GROUPS
By default, `bundle install` will install all gems in all groups
in your Gemfile(5), except those declared for a different platform.
However, you can explicitly tell Bundler to skip installing
certain groups with the `--without` option. This option takes
a space-separated list of groups.
While the `--without` option will skip _installing_ the gems in the
specified groups, it will still _download_ those gems and use them to
resolve the dependencies of every gem in your Gemfile(5).
This is so that installing a different set of groups on another
machine (such as a production server) will not change the
gems and versions that you have already developed and tested against.
`Bundler offers a rock-solid guarantee that the third-party
code you are running in development and testing is also the
third-party code you are running in production. You can choose
to exclude some of that code in different environments, but you
will never be caught flat-footed by different versions of
third-party code being used in different environments.`
For a simple illustration, consider the following Gemfile(5):
source 'https://rubygems.org'
gem 'sinatra'
group :production do
gem 'rack-perftools-profiler'
end
In this case, `sinatra` depends on any version of Rack (`>= 1.0`), while
`rack-perftools-profiler` depends on 1.x (`~> 1.0`).
When you run `bundle install --without production` in development, we
look at the dependencies of `rack-perftools-profiler` as well. That way,
you do not spend all your time developing against Rack 2.0, using new
APIs unavailable in Rack 1.x, only to have Bundler switch to Rack 1.2
when the `production` group _is_ used.
This should not cause any problems in practice, because we do not
attempt to `install` the gems in the excluded groups, and only evaluate
as part of the dependency resolution process.
This also means that you cannot include different versions of the same
gem in different groups, because doing so would result in different
sets of dependencies used in development and production. Because of
the vagaries of the dependency resolution process, this usually
affects more than the gems you list in your Gemfile(5), and can
(surprisingly) radically change the gems you are using.
## THE GEMFILE.LOCK
When you run `bundle install`, Bundler will persist the full names
and versions of all gems that you used (including dependencies of
the gems specified in the Gemfile(5)) into a file called `Gemfile.lock`.
Bundler uses this file in all subsequent calls to `bundle install`,
which guarantees that you always use the same exact code, even
as your application moves across machines.
Because of the way dependency resolution works, even a
seemingly small change (for instance, an update to a point-release
of a dependency of a gem in your Gemfile(5)) can result in radically
different gems being needed to satisfy all dependencies.
As a result, you `SHOULD` check your `Gemfile.lock` into version
control, in both applications and gems. If you do not, every machine that
checks out your repository (including your production server) will resolve all
dependencies again, which will result in different versions of
third-party code being used if `any` of the gems in the Gemfile(5)
or any of their dependencies have been updated.
When Bundler first shipped, the `Gemfile.lock` was included in the `.gitignore`
file included with generated gems. Over time, however, it became clear that
this practice forces the pain of broken dependencies onto new contributors,
while leaving existing contributors potentially unaware of the problem. Since
`bundle install` is usually the first step towards a contribution, the pain of
broken dependencies would discourage new contributors from contributing. As a
result, we have revised our guidance for gem authors to now recommend checking
in the lock for gems.
## CONSERVATIVE UPDATING
When you make a change to the Gemfile(5) and then run `bundle install`,
Bundler will update only the gems that you modified.
In other words, if a gem that you `did not modify` worked before
you called `bundle install`, it will continue to use the exact
same versions of all dependencies as it used before the update.
Let's take a look at an example. Here's your original Gemfile(5):
source 'https://rubygems.org'
gem 'actionpack', '2.3.8'
gem 'activemerchant'
In this case, both `actionpack` and `activemerchant` depend on
`activesupport`. The `actionpack` gem depends on `activesupport 2.3.8`
and `rack ~> 1.1.0`, while the `activemerchant` gem depends on
`activesupport >= 2.3.2`, `braintree >= 2.0.0`, and `builder >= 2.0.0`.
When the dependencies are first resolved, Bundler will select
`activesupport 2.3.8`, which satisfies the requirements of both
gems in your Gemfile(5).
Next, you modify your Gemfile(5) to:
source 'https://rubygems.org'
gem 'actionpack', '3.0.0.rc'
gem 'activemerchant'
The `actionpack 3.0.0.rc` gem has a number of new dependencies,
and updates the `activesupport` dependency to `= 3.0.0.rc` and
the `rack` dependency to `~> 1.2.1`.
When you run `bundle install`, Bundler notices that you changed
the `actionpack` gem, but not the `activemerchant` gem. It
evaluates the gems currently being used to satisfy its requirements:
* `activesupport 2.3.8`:
also used to satisfy a dependency in `activemerchant`,
which is not being updated
* `rack ~> 1.1.0`:
not currently being used to satisfy another dependency
Because you did not explicitly ask to update `activemerchant`,
you would not expect it to suddenly stop working after updating
`actionpack`. However, satisfying the new `activesupport 3.0.0.rc`
dependency of actionpack requires updating one of its dependencies.
Even though `activemerchant` declares a very loose dependency
that theoretically matches `activesupport 3.0.0.rc`, Bundler treats
gems in your Gemfile(5) that have not changed as an atomic unit
together with their dependencies. In this case, the `activemerchant`
dependency is treated as `activemerchant 1.7.1 + activesupport 2.3.8`,
so `bundle install` will report that it cannot update `actionpack`.
To explicitly update `actionpack`, including its dependencies
which other gems in the Gemfile(5) still depend on, run
`bundle update actionpack` (see `bundle update(1)`).
`Summary`: In general, after making a change to the Gemfile(5) , you
should first try to run `bundle install`, which will guarantee that no
other gem in the Gemfile(5) is impacted by the change. If that
does not work, run [bundle update(1)](bundle-update.1.html).

=================================================================
## SYNOPSIS
`bundle platform` [--ruby]
## DESCRIPTION
`platform` will display information from your Gemfile, Gemfile.lock, and Ruby
VM about your platform.
For instance, using this Gemfile(5):
source "https://rubygems.org"
ruby "1.9.3"
gem "rack"
If you run `bundle platform` on Ruby 1.9.3, it will display the following output:
Your platform is: x86_64-linux
Your app has gems that work on these platforms:
* ruby
Your Gemfile specifies a Ruby version requirement:
* ruby 1.9.3
Your current platform satisfies the Ruby version requirement.
`platform` will list all the platforms in your `Gemfile.lock` as well as the
`ruby` directive if applicable from your Gemfile(5). It will also let you know
if the `ruby` directive requirement has been met. If `ruby` directive doesn't
match the running Ruby VM, it will tell you what part does not.
## OPTIONS
* `--ruby`:
It will display the ruby directive information, so you don't have to
parse it from the Gemfile(5).

.SH "SYNOPSIS"
\fBbundle pristine\fR
.
.SH "DESCRIPTION"
\fBpristine\fR restores the installed gems in the bundle to their pristine condition using the local gem cache from RubyGems\. For git gems, a forced checkout will be performed\.
.
.P
For further explanation, \fBbundle pristine\fR ignores unpacked files on disk\. In other words, this command utilizes the local \fB\.gem\fR cache or the gem\'s git repository as if one were installing from scratch\.
.
.P
Note: the Bundler gem cannot be restored to its original state with \fBpristine\fR\. One also cannot use \fBbundle pristine\fR on gems with a \'path\' option in the Gemfile, because bundler has no original copy it can restore from\.
.
.P
When is it practical to use \fBbundle pristine\fR?
.
.P
It comes in handy when a developer is debugging a gem\. \fBbundle pristine\fR is a great way to get rid of experimental changes to a gem that one may not want\.
.
.P
Why use \fBbundle pristine\fR over \fBgem pristine \-\-all\fR?
.
.P
Both commands are very similar\. For context: \fBbundle pristine\fR, without arguments, cleans all gems from the lockfile\. Meanwhile, \fBgem pristine \-\-all\fR cleans all installed gems for that Ruby version\.
.
.P
If a developer forgets which gems in their project they might have been debugging, the Rubygems \fBgem pristine [GEMNAME]\fR command may be inconvenient\. One can avoid waiting for \fBgem pristine \-\-all\fR, and instead run \fBbundle pristine\fR\.

.
.SH "DESCRIPTION"
Install the gems specified in your Gemfile(5)\. If this is the first time you run bundle install (and a \fBGemfile\.lock\fR does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems\.
.
.P
If a \fBGemfile\.lock\fR does exist, and you have not updated your Gemfile(5), Bundler will fetch all remote sources, but use the dependencies specified in the \fBGemfile\.lock\fR instead of resolving dependencies\.
.
.P
If a \fBGemfile\.lock\fR does exist, and you have updated your Gemfile(5), Bundler will use the dependencies in the \fBGemfile\.lock\fR for all gems that you did not update, but will re\-resolve the dependencies of gems that you did update\. You can find more information about this update process below under \fICONSERVATIVE UPDATING\fR\.
.
.SH "OPTIONS"
The \fB\-\-clean\fR, \fB\-\-deployment\fR, \fB\-\-frozen\fR, \fB\-\-no\-prune\fR, \fB\-\-path\fR, \fB\-\-shebang\fR, \fB\-\-system\fR, \fB\-\-without\fR and \fB\-\-with\fR options are deprecated because they only make sense if they are applied to every subsequent \fBbundle install\fR run automatically and that requires \fBbundler\fR to silently remember them\. Since \fBbundler\fR will no longer remember CLI flags in future versions, \fBbundle config\fR (see bundle\-config(1)) should be used to apply them permanently\.
.
.TP
\fB\-\-binstubs[=<directory>]\fR
Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it in \fBbin/\fR\. This lets you link the binstub inside of an application to the exact gem version the application needs\.
.
.IP
Creates a directory (defaults to \fB~/bin\fR) and places any executables from the gem there\. These executables run in Bundler\'s context\. If used, you might add this directory to your environment\'s \fBPATH\fR variable\. For instance, if the \fBrails\fR gem comes with a \fBrails\fR executable, this flag will create a \fBbin/rails\fR executable that ensures that all referred dependencies will be resolved using the bundled gems\.
.
.TP
\fB\-\-clean\fR
On finishing the installation Bundler is going to remove any gems not present in the current Gemfile(5)\. Don\'t worry, gems currently in use will not be removed\.
.
.IP
This option is deprecated in favor of the \fBclean\fR setting\.
.
.TP
\fB\-\-deployment\fR
In \fIdeployment mode\fR, Bundler will \'roll\-out\' the bundle for production or CI use\. Please check carefully if you want to have this option enabled in your development environment\.
.
.IP
This option is deprecated in favor of the \fBdeployment\fR setting\.
.
.TP
\fB\-\-redownload\fR
Force download every gem, even if the required versions are already available locally\.
.
.TP
\fB\-\-frozen\fR
Do not allow the Gemfile\.lock to be updated after this install\. Exits non\-zero if there are going to be changes to the Gemfile\.lock\.
.
.IP
This option is deprecated in favor of the \fBfrozen\fR setting\.
.
.TP
\fB\-\-full\-index\fR
Bundler will not call Rubygems\' API endpoint (default) but download and cache a (currently big) index file of all gems\. Performance can be improved for large bundles that seldom change by enabling this option\.
.
.TP
\fB\-\-gemfile=<gemfile>\fR
The location of the Gemfile(5) which Bundler should use\. This defaults to a Gemfile(5) in the current working directory\. In general, Bundler will assume that the location of the Gemfile(5) is also the project\'s root and will try to find \fBGemfile\.lock\fR and \fBvendor/cache\fR relative to this location\.
.
.TP
\fB\-\-jobs=[<number>]\fR, \fB\-j[<number>]\fR
The maximum number of parallel download and install jobs\. The default is \fB1\fR\.
.
.TP
\fB\-\-local\fR
Do not attempt to connect to \fBrubygems\.org\fR\. Instead, Bundler will use the gems already present in Rubygems\' cache or in \fBvendor/cache\fR\. Note that if an appropriate platform\-specific gem exists on \fBrubygems\.org\fR it will not be found\.
.
.TP
\fB\-\-no\-cache\fR
Do not update the cache in \fBvendor/cache\fR with the newly bundled gems\. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install\.
.
.TP
\fB\-\-no\-prune\fR
Don\'t remove stale gems from the cache when the installation finishes\.
.
.IP
This option is deprecated in favor of the \fBno_prune\fR setting\.
.
.TP
\fB\-\-path=<path>\fR
The location to install the specified gems to\. This defaults to Rubygems\' setting\. Bundler shares this location with Rubygems, \fBgem install \.\.\.\fR will have gem installed there, too\. Therefore, gems installed without a \fB\-\-path \.\.\.\fR setting will show up by calling \fBgem list\fR\. Accordingly, gems installed to other locations will not get listed\.
.
.IP
This option is deprecated in favor of the \fBpath\fR setting\.
.
.TP
\fB\-\-quiet\fR
Do not print progress information to the standard output\. Instead, Bundler will exit using a status code (\fB$?\fR)\.
.
.TP
\fB\-\-retry=[<number>]\fR
Retry failed network or git requests for \fInumber\fR times\.
.
.TP
\fB\-\-shebang=<ruby\-executable>\fR
Uses the specified ruby executable (usually \fBruby\fR) to execute the scripts created with \fB\-\-binstubs\fR\. In addition, if you use \fB\-\-binstubs\fR together with \fB\-\-shebang jruby\fR these executables will be changed to execute \fBjruby\fR instead\.
.
.IP
This option is deprecated in favor of the \fBshebang\fR setting\.
.
.TP
\fB\-\-standalone[=<list>]\fR
Makes a bundle that can work without depending on Rubygems or Bundler at runtime\. A space separated list of groups to install has to be specified\. Bundler creates a directory named \fBbundle\fR and installs the bundle there\. It also generates a \fBbundle/bundler/setup\.rb\fR file to replace Bundler\'s own setup in the manner required\. Using this option implicitly sets \fBpath\fR, which is a [remembered option][REMEMBERED OPTIONS]\.
.
.TP
\fB\-\-system\fR
Installs the gems specified in the bundle to the system\'s Rubygems location\. This overrides any previous configuration of \fB\-\-path\fR\.
.
.IP
This option is deprecated in favor of the \fBsystem\fR setting\.
.
.TP
\fB\-\-trust\-policy=[<policy>]\fR
Apply the Rubygems security policy \fIpolicy\fR, where policy is one of \fBHighSecurity\fR, \fBMediumSecurity\fR, \fBLowSecurity\fR, \fBAlmostNoSecurity\fR, or \fBNoSecurity\fR\. For more details, please see the Rubygems signing documentation linked below in \fISEE ALSO\fR\.
.
.TP
\fB\-\-with=<list>\fR
A space\-separated list of groups referencing gems to install\. If an optional group is given it is installed\. If a group is given that is in the remembered list of groups given to \-\-without, it is removed from that list\.
.
.IP
This option is deprecated in favor of the \fBwith\fR setting\.
.
.TP
\fB\-\-without=<list>\fR
A space\-separated list of groups referencing gems to skip during installation\. If a group is given that is in the remembered list of groups given to \-\-with, it is removed from that list\.
.
.IP
This option is deprecated in favor of the \fBwithout\fR setting\.
.
.SH "DEPLOYMENT MODE"
Bundler\'s defaults are optimized for development\. To switch to defaults optimized for deployment and for CI, use the \fB\-\-deployment\fR flag\. Do not activate deployment mode on development machines, as it will cause an error when the Gemfile(5) is modified\.
.
.IP "1." 4
A \fBGemfile\.lock\fR is required\.
.
.IP
To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a \fBGemfile\.lock\fR is required\.
.
.IP
This is mainly to ensure that you remember to check your \fBGemfile\.lock\fR into version control\.
.
.IP "2." 4
The \fBGemfile\.lock\fR must be up to date
.
.IP
In development, you can modify your Gemfile(5) and re\-run \fBbundle install\fR to \fIconservatively update\fR your \fBGemfile\.lock\fR snapshot\.
.
.IP
In deployment, your \fBGemfile\.lock\fR should be up\-to\-date with changes made in your Gemfile(5)\.
.
.IP "3." 4
Gems are installed to \fBvendor/bundle\fR not your default system location
.
.IP
In development, it\'s convenient to share the gems used in your application with other applications and other scripts that run on the system\.
.
.IP
In deployment, isolation is a more important default\. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them\.
.
.IP
As a result, \fBbundle install \-\-deployment\fR installs gems to the \fBvendor/bundle\fR directory in the application\. This may be overridden using the \fB\-\-path\fR option\.
.
.IP "" 0
.
.SH "SUDO USAGE"
By default, Bundler installs gems to the same location as \fBgem install\fR\.
.
.P
In some cases, that location may not be writable by your Unix user\. In that case, Bundler will stage everything in a temporary directory, then ask you for your \fBsudo\fR password in order to copy the gems into their system location\.
.
.P
From your perspective, this is identical to installing the gems directly into the system\.
.
.P
You should never use \fBsudo bundle install\fR\. This is because several other steps in \fBbundle install\fR must be performed as the current user:
.
.IP "\(bu" 4
Updating your \fBGemfile\.lock\fR
.
.IP "\(bu" 4
Updating your \fBvendor/cache\fR, if necessary
.
.IP "\(bu" 4
Checking out private git repositories using your user\'s SSH keys
.
.IP "" 0
.
.P
Of these three, the first two could theoretically be performed by \fBchown\fRing the resulting files to \fB$SUDO_USER\fR\. The third, however, can only be performed by invoking the \fBgit\fR command as the current user\. Therefore, git gems are downloaded and installed into \fB~/\.bundle\fR rather than $GEM_HOME or $BUNDLE_PATH\.
.
.P
As a result, you should run \fBbundle install\fR as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location\.
.
.SH "INSTALLING GROUPS"
By default, \fBbundle install\fR will install all gems in all groups in your Gemfile(5), except those declared for a different platform\.
.
.P
However, you can explicitly tell Bundler to skip installing certain groups with the \fB\-\-without\fR option\. This option takes a space\-separated list of groups\.
.
.P
While the \fB\-\-without\fR option will skip \fIinstalling\fR the gems in the specified groups, it will still \fIdownload\fR those gems and use them to resolve the dependencies of every gem in your Gemfile(5)\.
.
.P
This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against\.
.
.P
\fBBundler offers a rock\-solid guarantee that the third\-party code you are running in development and testing is also the third\-party code you are running in production\. You can choose to exclude some of that code in different environments, but you will never be caught flat\-footed by different versions of third\-party code being used in different environments\.\fR
.
.P
For a simple illustration, consider the following Gemfile(5):
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'sinatra\'
group :production do
gem \'rack\-perftools\-profiler\'
end
.
.fi
.
.IP "" 0
.
.P
In this case, \fBsinatra\fR depends on any version of Rack (\fB>= 1\.0\fR), while \fBrack\-perftools\-profiler\fR depends on 1\.x (\fB~> 1\.0\fR)\.
.
.P
When you run \fBbundle install \-\-without production\fR in development, we look at the dependencies of \fBrack\-perftools\-profiler\fR as well\. That way, you do not spend all your time developing against Rack 2\.0, using new APIs unavailable in Rack 1\.x, only to have Bundler switch to Rack 1\.2 when the \fBproduction\fR group \fIis\fR used\.
.
.P
This should not cause any problems in practice, because we do not attempt to \fBinstall\fR the gems in the excluded groups, and only evaluate as part of the dependency resolution process\.
.
.P
This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production\. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using\.
.
.SH "THE GEMFILE\.LOCK"
When you run \fBbundle install\fR, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called \fBGemfile\.lock\fR\.
.
.P
Bundler uses this file in all subsequent calls to \fBbundle install\fR, which guarantees that you always use the same exact code, even as your application moves across machines\.
.
.P
Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point\-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies\.
.
.P
As a result, you \fBSHOULD\fR check your \fBGemfile\.lock\fR into version control, in both applications and gems\. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third\-party code being used if \fBany\fR of the gems in the Gemfile(5) or any of their dependencies have been updated\.
.
.P
When Bundler first shipped, the \fBGemfile\.lock\fR was included in the \fB\.gitignore\fR file included with generated gems\. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem\. Since \fBbundle install\fR is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing\. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems\.
.
.SH "CONSERVATIVE UPDATING"
When you make a change to the Gemfile(5) and then run \fBbundle install\fR, Bundler will update only the gems that you modified\.
.
.P
In other words, if a gem that you \fBdid not modify\fR worked before you called \fBbundle install\fR, it will continue to use the exact same versions of all dependencies as it used before the update\.
.
.P
Let\'s take a look at an example\. Here\'s your original Gemfile(5):
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'actionpack\', \'2\.3\.8\'
gem \'activemerchant\'
.
.fi
.
.IP "" 0
.
.P
In this case, both \fBactionpack\fR and \fBactivemerchant\fR depend on \fBactivesupport\fR\. The \fBactionpack\fR gem depends on \fBactivesupport 2\.3\.8\fR and \fBrack ~> 1\.1\.0\fR, while the \fBactivemerchant\fR gem depends on \fBactivesupport >= 2\.3\.2\fR, \fBbraintree >= 2\.0\.0\fR, and \fBbuilder >= 2\.0\.0\fR\.
.
.P
When the dependencies are first resolved, Bundler will select \fBactivesupport 2\.3\.8\fR, which satisfies the requirements of both gems in your Gemfile(5)\.
.
.P
Next, you modify your Gemfile(5) to:
.
.IP "" 4
.
.nf
source \'https://rubygems\.org\'
gem \'actionpack\', \'3\.0\.0\.rc\'
gem \'activemerchant\'
.
.fi
.
.IP "" 0
.
.P
The \fBactionpack 3\.0\.0\.rc\fR gem has a number of new dependencies, and updates the \fBactivesupport\fR dependency to \fB= 3\.0\.0\.rc\fR and the \fBrack\fR dependency to \fB~> 1\.2\.1\fR\.
.
.P
When you run \fBbundle install\fR, Bundler notices that you changed the \fBactionpack\fR gem, but not the \fBactivemerchant\fR gem\. It evaluates the gems currently being used to satisfy its requirements:
.
.TP
\fBactivesupport 2\.3\.8\fR
also used to satisfy a dependency in \fBactivemerchant\fR, which is not being updated
.
.TP
\fBrack ~> 1\.1\.0\fR
not currently being used to satisfy another dependency
.
.P
Because you did not explicitly ask to update \fBactivemerchant\fR, you would not expect it to suddenly stop working after updating \fBactionpack\fR\. However, satisfying the new \fBactivesupport 3\.0\.0\.rc\fR dependency of actionpack requires updating one of its dependencies\.
.
.P
Even though \fBactivemerchant\fR declares a very loose dependency that theoretically matches \fBactivesupport 3\.0\.0\.rc\fR, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies\. In this case, the \fBactivemerchant\fR dependency is treated as \fBactivemerchant 1\.7\.1 + activesupport 2\.3\.8\fR, so \fBbundle install\fR will report that it cannot update \fBactionpack\fR\.
.
.P
To explicitly update \fBactionpack\fR, including its dependencies which other gems in the Gemfile(5) still depend on, run \fBbundle update actionpack\fR (see \fBbundle update(1)\fR)\.
.
.P
\fBSummary\fR: In general, after making a change to the Gemfile(5) , you should first try to run \fBbundle install\fR, which will guarantee that no other gem in the Gemfile(5) is impacted by the change\. If that does not work, run bundle update(1) \fIbundle\-update\.1\.html\fR\.

Copy all of the \fB\.gem\fR files needed to run the application into the \fBvendor/cache\fR directory\. In the future, when running [bundle install(1)][bundle\-install], use the gems in the cache in preference to the ones on \fBrubygems\.org\fR\.

.
.SH "SUPPORT FOR MULTIPLE PLATFORMS"
When using gems that have different packages for different platforms, Bundler supports caching of gems for other platforms where the Gemfile has been resolved (i\.e\. present in the lockfile) in \fBvendor/cache\fR\. This needs to be enabled via the \fB\-\-all\-platforms\fR option\. This setting will be remembered in your local bundler configuration\.
.
.SH "REMOTE FETCHING"
By default, if you run \fBbundle install(1)\fR](bundle\-install\.1\.html) after running bundle cache(1) \fIbundle\-cache\.1\.html\fR, bundler will still connect to \fBrubygems\.org\fR to check whether a platform\-specific gem exists for any of the gems in \fBvendor/cache\fR\.
.
.P
For instance, consider this Gemfile(5):
.
.IP "" 4
.
.nf
source "https://rubygems\.org"
gem "nokogiri"
.
.fi
.
.IP "" 0
.
.P
If you run \fBbundle cache\fR under C Ruby, bundler will retrieve the version of \fBnokogiri\fR for the \fB"ruby"\fR platform\. If you deploy to JRuby and run \fBbundle install\fR, bundler is forced to check to see whether a \fB"java"\fR platformed \fBnokogiri\fR exists\.
.
.P
Even though the \fBnokogiri\fR gem for the Ruby platform is \fItechnically\fR acceptable on JRuby, it has a C extension that does not run on JRuby\. As a result, bundler will, by default, still connect to \fBrubygems\.org\fR to check whether it has a version of one of your gems more specific to your platform\.
.
.P
This problem is also not limited to the \fB"java"\fR platform\. A similar (common) problem can happen when developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux\.
.
.P
If you know for sure that the gems packaged in \fBvendor/cache\fR are appropriate for the platform you are on, you can run \fBbundle install \-\-local\fR to skip checking for more appropriate gems, and use the ones in \fBvendor/cache\fR\.
.
.P
One way to be sure that you have the right platformed versions of all your gems is to run \fBbundle cache\fR on an identical machine and check in the gems\. For instance, you can run \fBbundle cache\fR on an identical staging box during your staging process, and check in the \fBvendor/cache\fR before deploying to production\.
.
.P
By default, bundle cache(1) \fIbundle\-cache\.1\.html\fR fetches and also installs the gems to the default location\. To package the dependencies to \fBvendor/cache\fR without installing them to the local install location, you can run \fBbundle cache \-\-no\-install\fR\.

=====================================================================
## SYNOPSIS
`bundle update` <*gems> [--all]
[--group=NAME]
[--source=NAME]
[--local]
[--ruby]
[--bundler[=VERSION]]
[--full-index]
[--jobs=JOBS]
[--quiet]
[--patch|--minor|--major]
[--redownload]
[--strict]
[--conservative]
## DESCRIPTION
Update the gems specified (all gems, if `--all` flag is used), ignoring
the previously installed gems specified in the `Gemfile.lock`. In
general, you should use [bundle install(1)](bundle-install.1.html) to install the same exact
gems and versions across machines.
You would use `bundle update` to explicitly update the version of a
gem.
## OPTIONS
* `--all`:
Update all gems specified in Gemfile.
* `--group=<name>`, `-g=[<name>]`:
Only update the gems in the specified group. For instance, you can update all gems
in the development group with `bundle update --group development`. You can also
call `bundle update rails --group test` to update the rails gem and all gems in
the test group, for example.
* `--source=<name>`:
The name of a `:git` or `:path` source used in the Gemfile(5). For
instance, with a `:git` source of `http://github.com/rails/rails.git`,
you would call `bundle update --source rails`

## UPDATING ALL GEMS
If you run `bundle update --all`, bundler will ignore
any previously installed gems and resolve all dependencies again
based on the latest versions of all gems available in the sources.
Consider the following Gemfile(5):
source "https://rubygems.org"
gem "rails", "3.0.0.rc"
gem "nokogiri"
When you run [bundle install(1)](bundle-install.1.html) the first time, bundler will resolve
all of the dependencies, all the way down, and install what you need:
Fetching gem metadata from https://rubygems.org/.........
Resolving dependencies...
Installing builder 2.1.2
Installing abstract 1.0.0
Installing rack 1.2.8
Using bundler 1.7.6
Installing rake 10.4.0

Installing mime-types 1.25.1
Installing i18n 0.4.2
Installing mini_portile 0.6.1
Installing tzinfo 0.3.42
Installing rack-mount 0.6.14
Installing rack-test 0.5.7
Installing treetop 1.4.15
Installing thor 0.14.6
Installing activesupport 3.0.0.rc
Installing erubis 2.6.6
Installing activemodel 3.0.0.rc
Installing arel 0.4.0
Installing mail 2.2.20
Installing activeresource 3.0.0.rc
Installing actionpack 3.0.0.rc
Installing activerecord 3.0.0.rc
Installing actionmailer 3.0.0.rc
Installing railties 3.0.0.rc
Installing rails 3.0.0.rc
Installing nokogiri 1.6.5
Bundle complete! 2 Gemfile dependencies, 26 gems total.
Use `bundle show [gemname]` to see where a bundled gem is installed.
As you can see, even though you have two gems in the Gemfile(5), your application
needs 26 different gems in order to run. Bundler remembers the exact versions
it installed in `Gemfile.lock`. The next time you run [bundle install(1)](bundle-install.1.html), bundler skips
the dependency resolution and installs the same gems as it installed last time.
After checking in the `Gemfile.lock` into version control and cloning it on another
machine, running [bundle install(1)](bundle-install.1.html) will _still_ install the gems that you installed
last time. You don't need to worry that a new release of `erubis` or `mail` changes
the gems you use.
However, from time to time, you might want to update the gems you are using to the
newest versions that still match the gems in your Gemfile(5).
To do this, run `bundle update --all`, which will ignore the `Gemfile.lock`, and resolve
all the dependencies again. Keep in mind that this process can result in a significantly
different set of the 25 gems, based on the requirements of new gems that the gem
authors released since the last time you ran `bundle update --all`.
## UPDATING A LIST OF GEMS
Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the
gems that you specified locked to the versions in the `Gemfile.lock`.
For instance, in the scenario above, imagine that `nokogiri` releases version `1.4.4`, and
you want to update it _without_ updating Rails and all of its dependencies. To do this,
run `bundle update nokogiri`.
Bundler will update `nokogiri` and any of its dependencies, but leave alone Rails and
its dependencies.
## OVERLAPPING DEPENDENCIES
Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same
second-level dependency. For instance, consider the case of `thin` and
`rack-perftools-profiler`.
source "https://rubygems.org"
gem "thin"
gem "rack-perftools-profiler"
The `thin` gem depends on `rack >= 1.0`, while `rack-perftools-profiler` depends
on `rack ~> 1.0`. If you run bundle install, you get:
Fetching source index for https://rubygems.org/
Installing daemons (1.1.0)
Installing eventmachine (0.12.10) with native extensions
Installing open4 (1.0.1)
Installing perftools.rb (0.4.7) with native extensions
Installing rack (1.2.1)
Installing rack-perftools_profiler (0.0.2)
Installing thin (1.2.7) with native extensions
Using bundler (1.0.0.rc.3)
In this case, the two gems have their own set of dependencies, but they share
`rack` in common. If you run `bundle update thin`, bundler will update `daemons`,
`eventmachine` and `rack`, which are dependencies of `thin`, but not `open4` or
`perftools.rb`, which are dependencies of `rack-perftools_profiler`. Note that
`bundle update thin` will update `rack` even though it's _also_ a dependency of
`rack-perftools_profiler`.
In short, by default, when you update a gem using `bundle update`, bundler will
update all dependencies of that gem, including those that are also dependencies
of another gem.
To prevent updating indirect dependencies, prior to version 1.14 the only option
was the `CONSERVATIVE UPDATING` behavior in [bundle install(1)](bundle-install.1.html):
In this scenario, updating the `thin` version manually in the Gemfile(5),
and then running [bundle install(1)](bundle-install.1.html) will only update `daemons` and `eventmachine`,
but not `rack`. For more information, see the `CONSERVATIVE UPDATING` section
of [bundle install(1)](bundle-install.1.html).
Starting with 1.14, specifying the `--conservative` option will also prevent indirect
dependencies from being updated.
## PATCH LEVEL OPTIONS
Version 1.14 introduced 4 patch-level options that will influence how gem
versions are resolved. One of the following options can be used: `--patch`,
`--minor` or `--major`. `--strict` can be added to further influence resolution.
* `--patch`:
Prefer updating only to next patch version.
* `--minor`:
Prefer updating only to next minor version.
* `--major`:
Prefer updating to next major version (default).
* `--strict`:
Do not allow any gem to be updated past latest `--patch` | `--minor` | `--major`.
When Bundler is resolving what versions to use to satisfy declared
requirements in the Gemfile or in parent gems, it looks up all
available versions, filters out any versions that don't satisfy
the requirement, and then, by default, sorts them from newest to
oldest, considering them in that order.
Providing one of the patch level options (e.g. `--patch`) changes the
sort order of the satisfying versions, causing Bundler to consider the
latest `--patch` or `--minor` version available before other versions.
Note that versions outside the stated patch level could still be
resolved to if necessary to find a suitable dependency graph.
For example, if gem 'foo' is locked at 1.0.2, with no gem requirement
defined in the Gemfile, and versions 1.0.3, 1.0.4, 1.1.0, 1.1.1, 2.0.0
all exist, the default order of preference by default (`--major`) will
be "2.0.0, 1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2".
If the `--patch` option is used, the order of preference will change to
"1.0.4, 1.0.3, 1.0.2, 1.1.1, 1.1.0, 2.0.0".
If the `--minor` option is used, the order of preference will change to
"1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2, 2.0.0".
Combining the `--strict` option with any of the patch level options
will remove any versions beyond the scope of the patch level option,
to ensure that no gem is updated that far.
To continue the previous example, if both `--patch` and `--strict`
options are used, the available versions for resolution would be
"1.0.4, 1.0.3, 1.0.2". If `--minor` and `--strict` are used, it would
be "1.1.1, 1.1.0, 1.0.4, 1.0.3, 1.0.2".
Gem requirements as defined in the Gemfile will still be the first
determining factor for what versions are available. If the gem
requirement for `foo` in the Gemfile is '~> 1.0', that will accomplish
the same thing as providing the `--minor` and `--strict` options.
## PATCH LEVEL EXAMPLES
Given the following gem specifications:
foo 1.4.3, requires: ~> bar 2.0
foo 1.4.4, requires: ~> bar 2.0
foo 1.4.5, requires: ~> bar 2.1
foo 1.5.0, requires: ~> bar 2.1
foo 1.5.1, requires: ~> bar 3.0
bar with versions 2.0.3, 2.0.4, 2.1.0, 2.1.1, 3.0.0
Gemfile:
gem 'foo'
Gemfile.lock:
foo (1.4.3)
bar (~> 2.0)
bar (2.0.3)
Cases:
# Command Line Result
------------------------------------------------------------
1 bundle update --patch 'foo 1.4.5', 'bar 2.1.1'
2 bundle update --patch foo 'foo 1.4.5', 'bar 2.1.1'
3 bundle update --minor 'foo 1.5.1', 'bar 3.0.0'
4 bundle update --minor --strict 'foo 1.5.0', 'bar 2.1.1'
5 bundle update --patch --strict 'foo 1.4.4', 'bar 2.0.4'
In case 1, bar is upgraded to 2.1.1, a minor version increase, because
the dependency from foo 1.4.5 required it.
In case 2, only foo is requested to be unlocked, but bar is also
allowed to move because it's not a declared dependency in the Gemfile.
In case 3, bar goes up a whole major release, because a minor increase
is preferred now for foo, and when it goes to 1.5.1, it requires 3.0.0
of bar.
In case 4, foo is preferred up to a minor version, but 1.5.1 won't work
because the --strict flag removes bar 3.0.0 from consideration since
it's a major increment.
In case 5, both foo and bar have any minor or major increments removed
from consideration because of the --strict flag, so the most they can
move is up to 1.4.4 and 2.0.4.
## RECOMMENDED WORKFLOW
In general, when working with an application managed with bundler, you should
use the following workflow:
* After you create your Gemfile(5) for the first time, run
$ bundle install
* Check the resulting `Gemfile.lock` into version control
$ git add Gemfile.lock
* When checking out this repository on another development machine, run
$ bundle install
* When checking out this repository on a deployment machine, run
$ bundle install --deployment
* After changing the Gemfile(5) to reflect a new or update dependency, run
$ bundle install
* Make sure to check the updated `Gemfile.lock` into version control
$ git add Gemfile.lock
* If [bundle install(1)](bundle-install.1.html) reports a conflict, manually update the specific
gems that you changed in the Gemfile(5)
$ bundle update rails thin
* If you want to update all the gems to the latest possible versions that
still match the gems listed in the Gemfile(5), run
$ bundle update --all

## SYNOPSIS
`bundle lock` [--update]
[--local]
[--print]
[--lockfile=PATH]
[--full-index]
[--add-platform]
[--remove-platform]
[--patch]
[--minor]
[--major]
[--strict]

## DESCRIPTION
Lock the gems specified in Gemfile.
## OPTIONS
* `--update=<*gems>`:
Ignores the existing lockfile. Resolve then updates lockfile. Taking a list
of gems or updating all gems if no list is given.
* `--local`:
Do not attempt to connect to `rubygems.org`. Instead, Bundler will use the
gems already present in Rubygems' cache or in `vendor/cache`. Note that if a
appropriate platform-specific gem exists on `rubygems.org` it will not be
found.
* `--print`:
Prints the lockfile to STDOUT instead of writing to the file system.
* `--lockfile=<path>`:
The path where the lockfile should be written to.
* `--full-index`:
Fall back to using the single-file index of all gems.
* `--add-platform`:
Add a new platform to the lockfile, re-resolving for the addition of that
platform.
* `--remove-platform`:
Remove a platform from the lockfile.
* `--patch`:
If updating, prefer updating only to next patch version.
* `--minor`:
If updating, prefer updating only to next minor version.
* `--major`:
If updating, prefer updating to next major version (default).
* `--strict`:
If updating, do not allow any gem to be updated past latest --patch | --minor | --major.
* `--conservative`:
If updating, use bundle install conservative update behavior and do not allow shared dependencies to be updated.
## UPDATING ALL GEMS
If you run `bundle lock` with `--update` option without list of gems, bundler will
ignore any previously installed gems and resolve all dependencies again based
on the latest versions of all gems available in the sources.
## UPDATING A LIST OF GEMS
Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of
the gems that you specified locked to the versions in the `Gemfile.lock`.
For instance, you only want to update `nokogiri`, run `bundle lock --update nokogiri`.
Bundler will update `nokogiri` and any of its dependencies, but leave the rest of the
gems that you specified locked to the versions in the `Gemfile.lock`.
## SUPPORTING OTHER PLATFORMS
If you want your bundle to support platforms other than the one you're running
locally, you can run `bundle lock --add-platform PLATFORM` to add PLATFORM to
the lockfile, force bundler to re-resolve and consider the new platform when
picking gems, all without needing to have a machine that matches PLATFORM handy
to install those platform-specific gems on.
For a full explanation of gem platforms, see `gem help platform`.

================================================================
## SYNOPSIS
`bundle exec` [--keep-file-descriptors] <command>
## DESCRIPTION
This command executes the command, making all gems specified in the
[`Gemfile(5)`][Gemfile(5)] available to `require` in Ruby programs.
Essentially, if you would normally have run something like
`rspec spec/my_spec.rb`, and you want to use the gems specified
in the [`Gemfile(5)`][Gemfile(5)] and installed via [bundle install(1)](bundle-install.1.html), you
should run `bundle exec rspec spec/my_spec.rb`.
Note that `bundle exec` does not require that an executable is
available on your shell's `$PATH`.
## OPTIONS
* `--keep-file-descriptors`:
Exec in Ruby 2.0 began discarding non-standard file descriptors. When this
flag is passed, exec will revert to the 1.9 behaviour of passing all file
descriptors to the new process.
## BUNDLE INSTALL --BINSTUBS
If you use the `--binstubs` flag in [bundle install(1)](bundle-install.1.html), Bundler will
automatically create a directory (which defaults to `app_root/bin`)
containing all of the executables available from gems in the bundle.
After using `--binstubs`, `bin/rspec spec/my_spec.rb` is identical
to `bundle exec rspec spec/my_spec.rb`.
## ENVIRONMENT MODIFICATIONS
`bundle exec` makes a number of changes to the shell environment,
then executes the command you specify in full.
* make sure that it's still possible to shell out to `bundle`
from inside a command invoked by `bundle exec` (using
`$BUNDLE_BIN_PATH`)
* put the directory containing executables (like `rails`, `rspec`,
`rackup`) for your bundle on `$PATH`
* make sure that if bundler is invoked in the subshell, it uses
the same `Gemfile` (by setting `BUNDLE_GEMFILE`)
* add `-rbundler/setup` to `$RUBYOPT`, which makes sure that
Ruby programs invoked in the subshell can see the gems in
the bundle
It also modifies Rubygems:
* disallow loading additional gems not in the bundle
* modify the `gem` method to be a no-op if a gem matching
the requirements is in the bundle, and to raise a
`Gem::LoadError` if it's not
* Define `Gem.refresh` to be a no-op, since the source
index is always frozen when using bundler, and to
prevent gems from the system leaking into the environment
* Override `Gem.bin_path` to use the gems in the bundle,
making system executables work
* Add all gems in the bundle into Gem.loaded_specs
Finally, `bundle exec` also implicitly modifies `Gemfile.lock` if the lockfile
and the Gemfile do not match. Bundler needs the Gemfile to determine things
such as a gem's groups, `autorequire`, and platforms, etc., and that
information isn't stored in the lockfile. The Gemfile and lockfile must be
synced in order to `bundle exec` successfully, so `bundle exec`
updates the lockfile beforehand.
### Loading
By default, when attempting to `bundle exec` to a file with a ruby shebang,
Bundler will `Kernel.load` that file instead of using `Kernel.exec`. For the
vast majority of cases, this is a performance improvement. In a rare few cases,
this could cause some subtle side-effects (such as dependence on the exact
contents of `$0` or `__FILE__`) and the optimization can be disabled by enabling
the `disable_exec_load` setting.
### Shelling out
Any Ruby code that opens a subshell (like `system`, backticks, or `%x{}`) will
automatically use the current Bundler environment. If you need to shell out to
a Ruby command that is not part of your current bundle, use the
`with_clean_env` method with a block. Any subshells created inside the block
will be given the environment present before Bundler was activated. For
example, Homebrew commands run Ruby, but don't work inside a bundle:
Bundler.with_clean_env do
`brew install wget`
end
Using `with_clean_env` is also necessary if you are shelling out to a different
bundle. Any Bundler commands run in a subshell will inherit the current
Gemfile, so commands that need to run in the context of a different bundle also
need to use `with_clean_env`.
Bundler.with_clean_env do
Dir.chdir "/other/bundler/project" do
`bundle exec ./script`
end
end
Bundler provides convenience helpers that wrap `system` and `exec`, and they
can be used like this:
Bundler.clean_system('brew install wget')
Bundler.clean_exec('brew install wget')
## RUBYGEMS PLUGINS
At present, the Rubygems plugin system requires all files
named `rubygems_plugin.rb` on the load path of _any_ installed
gem when any Ruby code requires `rubygems.rb`. This includes
executables installed into the system, like `rails`, `rackup`,
and `rspec`.
Since Rubygems plugins can contain arbitrary Ruby code, they
commonly end up activating themselves or their dependencies.
For instance, the `gemcutter 0.5` gem depended on `json_pure`.
If you had that version of gemcutter installed (even if
you _also_ had a newer version without this problem), Rubygems
would activate `gemcutter 0.5` and `json_pure <latest>`.
If your Gemfile(5) also contained `json_pure` (or a gem
with a dependency on `json_pure`), the latest version on
your system might conflict with the version in your
Gemfile(5), or the snapshot version in your `Gemfile.lock`.
If this happens, bundler will say:
You have already activated json_pure 1.4.6 but your Gemfile
requires json_pure 1.4.3. Consider using bundle exec.
In this situation, you almost certainly want to remove the
underlying gem with the problematic gem plugin. In general,
the authors of these plugins (in this case, the `gemcutter`
gem) have released newer versions that are more careful in
their plugins.
You can find a list of all the gems containing gem plugins
by running
ruby -rrubygems -e "puts Gem.find_files('rubygems_plugin.rb')"
At the very least, you should remove all but the newest
version of each gem plugin, and also remove all gem plugins
that you aren't using (`gem uninstall gem_name`).

====================================================================
## SYNOPSIS
`bundle gem` <GEM_NAME> [OPTIONS]
## DESCRIPTION
Generates a directory named `GEM_NAME` with a `Rakefile`, `GEM_NAME.gemspec`,
and other supporting files and directories that can be used to develop a
rubygem with that name.
Run `rake -T` in the resulting project for a list of Rake tasks that can be used
to test and publish the gem to rubygems.org.
The generated project skeleton can be customized with OPTIONS, as explained
below. Note that these options can also be specified via Bundler's global
configuration file using the following names:
* `gem.coc`
* `gem.mit`
* `gem.test`
## OPTIONS
* `--exe` or `-b` or `--bin`:
Specify that Bundler should create a binary executable (as `exe/GEM_NAME`)
in the generated rubygem project. This binary will also be added to the
`GEM_NAME.gemspec` manifest. This behavior is disabled by default.
* `--no-exe`:
Do not create a binary (overrides `--exe` specified in the global config).
* `--coc`:
Add a `CODE_OF_CONDUCT.md` file to the root of the generated project. If
this option is unspecified, an interactive prompt will be displayed and the
answer will be saved in Bundler's global config for future `bundle gem` use.
* `--no-coc`:
Do not create a `CODE_OF_CONDUCT.md` (overrides `--coc` specified in the
global config).
* `--ext`:
Add boilerplate for C extension code to the generated project. This behavior
is disabled by default.
* `--no-ext`:
Do not add C extension code (overrides `--ext` specified in the global
config).
* `--mit`:
Add an MIT license to a `LICENSE.txt` file in the root of the generated
project. Your name from the global git config is used for the copyright
statement. If this option is unspecified, an interactive prompt will be
displayed and the answer will be saved in Bundler's global config for future
`bundle gem` use.
* `--no-mit`:
Do not create a `LICENSE.txt` (overrides `--mit` specified in the global
config).
* `-t`, `--test=minitest`, `--test=rspec`, `--test=test-unit`:
Specify the test framework that Bundler should use when generating the
project. Acceptable values are `minitest`, `rspec` and `test-unit`. The
`GEM_NAME.gemspec` will be configured and a skeleton test/spec directory will
be created based on this option. Given no option is specified:
When Bundler is configured to generate tests, this defaults to Bundler's
global config setting `gem.test`.
When Bundler is configured to not generate tests, an interactive prompt will
be displayed and the answer will be used for the current rubygem project.
When Bundler is unconfigured, an interactive prompt will be displayed and
the answer will be saved in Bundler's global config for future `bundle gem`
use.
* `--ci`, `--ci=github`, `--ci=travis`, `--ci=gitlab`, `--ci=circle`:
Specify the continuous integration service that Bundler should use when
generating the project. Acceptable values are `github`, `travis`, `gitlab`
and `circle`. A configuration file will be generated in the project directory.
Given no option is specified:
When Bundler is configured to generate CI files, this defaults to Bundler's
global config setting `gem.ci`.
When Bundler is configured to not generate CI files, an interactive prompt
will be displayed and the answer will be used for the current rubygem project.
When Bundler is unconfigured, an interactive prompt will be displayed and
the answer will be saved in Bundler's global config for future `bundle gem`
use.
* `--linter`, `--linter=rubocop`, `--linter=standard`:
Specify the linter and code formatter that Bundler should add to the
project's development dependencies. Acceptable values are `rubocop` and
`standard`. A configuration file will be generated in the project directory.
Given no option is specified:
When Bundler is configured to add a linter, this defaults to Bundler's
global config setting `gem.linter`.
When Bundler is configured not to add a linter, an interactive prompt
will be displayed and the answer will be used for the current rubygem project.
When Bundler is unconfigured, an interactive prompt will be displayed and
the answer will be saved in Bundler's global config for future `bundle gem`
use.
* `-e`, `--edit[=EDITOR]`:
Open the resulting GEM_NAME.gemspec in EDITOR, or the default editor if not
specified. The default is `$BUNDLER_EDITOR`, `$VISUAL`, or `$EDITOR`.

.TH "BUNDLE\-EXEC" "1" "December 2021" "" ""
.
.SH "NAME"
\fBbundle\-exec\fR \- Execute a command in the context of the bundle
.
.SH "SYNOPSIS"
\fBbundle exec\fR [\-\-keep\-file\-descriptors] \fIcommand\fR
.
.SH "DESCRIPTION"
This command executes the command, making all gems specified in the [\fBGemfile(5)\fR][Gemfile(5)] available to \fBrequire\fR in Ruby programs\.
.
.P
Essentially, if you would normally have run something like \fBrspec spec/my_spec\.rb\fR, and you want to use the gems specified in the [\fBGemfile(5)\fR][Gemfile(5)] and installed via bundle install(1) \fIbundle\-install\.1\.html\fR, you should run \fBbundle exec rspec spec/my_spec\.rb\fR\.
.
.P
Note that \fBbundle exec\fR does not require that an executable is available on your shell\'s \fB$PATH\fR\.
.
.SH "OPTIONS"
.
.TP
\fB\-\-keep\-file\-descriptors\fR
Exec in Ruby 2\.0 began discarding non\-standard file descriptors\. When this flag is passed, exec will revert to the 1\.9 behaviour of passing all file descriptors to the new process\.
.
.SH "BUNDLE INSTALL \-\-BINSTUBS"
If you use the \fB\-\-binstubs\fR flag in bundle install(1) \fIbundle\-install\.1\.html\fR, Bundler will automatically create a directory (which defaults to \fBapp_root/bin\fR) containing all of the executables available from gems in the bundle\.
.
.P
After using \fB\-\-binstubs\fR, \fBbin/rspec spec/my_spec\.rb\fR is identical to \fBbundle exec rspec spec/my_spec\.rb\fR\.
.
.SH "ENVIRONMENT MODIFICATIONS"
\fBbundle exec\fR makes a number of changes to the shell environment, then executes the command you specify in full\.
.
.IP "\(bu" 4
make sure that it\'s still possible to shell out to \fBbundle\fR from inside a command invoked by \fBbundle exec\fR (using \fB$BUNDLE_BIN_PATH\fR)
.
.IP "\(bu" 4
put the directory containing executables (like \fBrails\fR, \fBrspec\fR, \fBrackup\fR) for your bundle on \fB$PATH\fR
.
.IP "\(bu" 4
make sure that if bundler is invoked in the subshell, it uses the same \fBGemfile\fR (by setting \fBBUNDLE_GEMFILE\fR)
.
.IP "\(bu" 4
add \fB\-rbundler/setup\fR to \fB$RUBYOPT\fR, which makes sure that Ruby programs invoked in the subshell can see the gems in the bundle
.
.IP "" 0
.
.P
It also modifies Rubygems:
.
.IP "\(bu" 4
disallow loading additional gems not in the bundle
.
.IP "\(bu" 4
modify the \fBgem\fR method to be a no\-op if a gem matching the requirements is in the bundle, and to raise a \fBGem::LoadError\fR if it\'s not
.
.IP "\(bu" 4
Define \fBGem\.refresh\fR to be a no\-op, since the source index is always frozen when using bundler, and to prevent gems from the system leaking into the environment
.
.IP "\(bu" 4
Override \fBGem\.bin_path\fR to use the gems in the bundle, making system executables work
.
.IP "\(bu" 4
Add all gems in the bundle into Gem\.loaded_specs
.
.IP "" 0
.
.P
Finally, \fBbundle exec\fR also implicitly modifies \fBGemfile\.lock\fR if the lockfile and the Gemfile do not match\. Bundler needs the Gemfile to determine things such as a gem\'s groups, \fBautorequire\fR, and platforms, etc\., and that information isn\'t stored in the lockfile\. The Gemfile and lockfile must be synced in order to \fBbundle exec\fR successfully, so \fBbundle exec\fR updates the lockfile beforehand\.
.
.SS "Loading"
By default, when attempting to \fBbundle exec\fR to a file with a ruby shebang, Bundler will \fBKernel\.load\fR that file instead of using \fBKernel\.exec\fR\. For the vast majority of cases, this is a performance improvement\. In a rare few cases, this could cause some subtle side\-effects (such as dependence on the exact contents of \fB$0\fR or \fB__FILE__\fR) and the optimization can be disabled by enabling the \fBdisable_exec_load\fR setting\.
.
.SS "Shelling out"
Any Ruby code that opens a subshell (like \fBsystem\fR, backticks, or \fB%x{}\fR) will automatically use the current Bundler environment\. If you need to shell out to a Ruby command that is not part of your current bundle, use the \fBwith_clean_env\fR method with a block\. Any subshells created inside the block will be given the environment present before Bundler was activated\. For example, Homebrew commands run Ruby, but don\'t work inside a bundle:
.
.IP "" 4
.
.nf
Bundler\.with_clean_env do
`brew install wget`
end
.
.fi
.
.IP "" 0
.
.P
Using \fBwith_clean_env\fR is also necessary if you are shelling out to a different bundle\. Any Bundler commands run in a subshell will inherit the current Gemfile, so commands that need to run in the context of a different bundle also need to use \fBwith_clean_env\fR\.
.
.IP "" 4
.
.nf
Bundler\.with_clean_env do
Dir\.chdir "/other/bundler/project" do
`bundle exec \./script`
end
end
.
.fi
.
.IP "" 0
.
.P
Bundler provides convenience helpers that wrap \fBsystem\fR and \fBexec\fR, and they can be used like this:
.
.IP "" 4
.
.nf
Bundler\.clean_system(\'brew install wget\')
Bundler\.clean_exec(\'brew install wget\')
.
.fi
.
.IP "" 0
.
.SH "RUBYGEMS PLUGINS"
At present, the Rubygems plugin system requires all files named \fBrubygems_plugin\.rb\fR on the load path of \fIany\fR installed gem when any Ruby code requires \fBrubygems\.rb\fR\. This includes executables installed into the system, like \fBrails\fR, \fBrackup\fR, and \fBrspec\fR\.
.
.P
Since Rubygems plugins can contain arbitrary Ruby code, they commonly end up activating themselves or their dependencies\.
.
.P
For instance, the \fBgemcutter 0\.5\fR gem depended on \fBjson_pure\fR\. If you had that version of gemcutter installed (even if you \fIalso\fR had a newer version without this problem), Rubygems would activate \fBgemcutter 0\.5\fR and \fBjson_pure <latest>\fR\.
.
.P
If your Gemfile(5) also contained \fBjson_pure\fR (or a gem with a dependency on \fBjson_pure\fR), the latest version on your system might conflict with the version in your Gemfile(5), or the snapshot version in your \fBGemfile\.lock\fR\.
.
.P
If this happens, bundler will say:
.
.IP "" 4
.
.nf
You have already activated json_pure 1\.4\.6 but your Gemfile
requires json_pure 1\.4\.3\. Consider using bundle exec\.
.
.fi
.
.IP "" 0
.
.P
In this situation, you almost certainly want to remove the underlying gem with the problematic gem plugin\. In general, the authors of these plugins (in this case, the \fBgemcutter\fR gem) have released newer versions that are more careful in their plugins\.
.
.P
You can find a list of all the gems containing gem plugins by running
.
.IP "" 4
.
.nf
ruby \-rrubygems \-e "puts Gem\.find_files(\'rubygems_plugin\.rb\')"
.
.fi
.
.IP "" 0
.
.P
At the very least, you should remove all but the newest version of each gem plugin, and also remove all gem plugins that you aren\'t using (\fBgem uninstall gem_name\fR)\.

##
# Persistent connections for Net::HTTP
#
# Bundler::Persistent::Net::HTTP::Persistent maintains persistent connections across all the
# servers you wish to talk to. For each host:port you communicate with a
# single persistent connection is created.
#
# Connections will be shared across threads through a connection pool to
# increase reuse of connections.
#
# You can shut down any remaining HTTP connections when done by calling
# #shutdown.
#
# Example:
#
# require 'bundler/vendor/net-http-persistent/lib/net/http/persistent'
#
# uri = Bundler::URI 'http://example.com/awesome/web/service'
#
# http = Bundler::Persistent::Net::HTTP::Persistent.new
#
# # perform a GET
# response = http.request uri
#
# # or
#
# get = Net::HTTP::Get.new uri.request_uri
# response = http.request get
#
# # create a POST
# post_uri = uri + 'create'
# post = Net::HTTP::Post.new post_uri.path
# post.set_form_data 'some' => 'cool data'
#
# # perform the POST, the Bundler::URI is always required
# response http.request post_uri, post
#
# Note that for GET, HEAD and other requests that do not have a body you want
# to use Bundler::URI#request_uri not Bundler::URI#path. The request_uri contains the query
# params which are sent in the body for other requests.
#
# == TLS/SSL
#
# TLS connections are automatically created depending upon the scheme of the
# Bundler::URI. TLS connections are automatically verified against the default
# certificate store for your computer. You can override this by changing
# verify_mode or by specifying an alternate cert_store.
#
# Here are the TLS settings, see the individual methods for documentation:
#
# #certificate :: This client's certificate
# #ca_file :: The certificate-authorities
# #ca_path :: Directory with certificate-authorities
# #cert_store :: An SSL certificate store
# #ciphers :: List of SSl ciphers allowed
# #private_key :: The client's SSL private key
# #reuse_ssl_sessions :: Reuse a previously opened SSL session for a new
# connection
# #ssl_timeout :: Session lifetime
# #ssl_version :: Which specific SSL version to use
# #verify_callback :: For server certificate verification
# #verify_depth :: Depth of certificate verification
# #verify_mode :: How connections should be verified
#
# == Proxies
#
# A proxy can be set through #proxy= or at initialization time by providing a
# second argument to ::new. The proxy may be the Bundler::URI of the proxy server or
# <code>:ENV</code> which will consult environment variables.
#
# See #proxy= and #proxy_from_env for details.
#
# == Headers
#
# Headers may be specified for use in every request. #headers are appended to
# any headers on the request. #override_headers replace existing headers on
# the request.
#
# The difference between the two can be seen in setting the User-Agent. Using
# <code>http.headers['User-Agent'] = 'MyUserAgent'</code> will send "Ruby,
# MyUserAgent" while <code>http.override_headers['User-Agent'] =
# 'MyUserAgent'</code> will send "MyUserAgent".
#
# == Tuning
#
# === Segregation
#
# Each Bundler::Persistent::Net::HTTP::Persistent instance has its own pool of connections. There
# is no sharing with other instances (as was true in earlier versions).
#
# === Idle Timeout
#
# If a connection hasn't been used for this number of seconds it will
# automatically be reset upon the next use to avoid attempting to send to a
# closed connection. The default value is 5 seconds. nil means no timeout.
# Set through #idle_timeout.
#
# Reducing this value may help avoid the "too many connection resets" error
# when sending non-idempotent requests while increasing this value will cause
# fewer round-trips.
#
# === Read Timeout
#
# The amount of time allowed between reading two chunks from the socket. Set
# through #read_timeout
#
# === Max Requests
#

# command cannot be guessed by name, it can also be supplied as second argument.
#
# You can also supply the arguments, options and configuration values for
# the command to be invoked, if none is given, the same values used to
# initialize the invoker are used to initialize the invoked.
#
# When no name is given, it will invoke the default command of the current class.
#
# ==== Examples
#
# class A < Bundler::Thor
# def foo
# invoke :bar
# invoke "b:hello", ["Erik"]
# end
#
# def bar
# invoke "b:hello", ["Erik"]
# end
# end
#
# class B < Bundler::Thor
# def hello(name)
# puts "hello #{name}"
# end
# end
#
# You can notice that the method "foo" above invokes two commands: "bar",
# which belongs to the same class and "hello" which belongs to the class B.
#
# By using an invocation system you ensure that a command is invoked only once.
# In the example above, invoking "foo" will invoke "b:hello" just once, even
# if it's invoked later by "bar" method.
#
# When class A invokes class B, all arguments used on A initialization are
# supplied to B. This allows lazy parse of options. Let's suppose you have
# some rspec commands:
#
# class Rspec < Bundler::Thor::Group
# class_option :mock_framework, :type => :string, :default => :rr
#
# def invoke_mock_framework
# invoke "rspec:#{options[:mock_framework]}"

# As you noticed, it invokes the given mock framework, which might have its
# own options:
#
# class Rspec::RR < Bundler::Thor::Group
# class_option :style, :type => :string, :default => :mock
# end
#
# Since it's not rspec concern to parse mock framework options, when RR
# is invoked all options are parsed again, so RR can extract only the options
# that it's going to use.
#
# If you want Rspec::RR to be initialized with its own set of options, you
# have to do that explicitly:
#
# invoke "rspec:rr", [], :style => :foo
#
# Besides giving an instance, you can also give a class to invoke:
#
# invoke Rspec::RR, [], :style => :foo

# Copies recursively the files from source directory to root directory.
# If any of the files finishes with .tt, it's considered to be a template
# and is placed in the destination without the extension .tt. If any
# empty directory is found, it's copied and all .empty_directory files are
# ignored. If any file name is wrapped within % signs, the text within
# the % signs will be executed as a method and replaced with the returned
# value. Let's suppose a doc directory with the following files:
#
# doc/
# components/.empty_directory
# README
# rdoc.rb.tt
# %app_name%.rb
#
# When invoked as:
#

# It will create a doc directory in the destination with the following

# Besides, arguments are used inside your code as an accessor (self.argument),
# while options are all kept in a hash (self.options).

# Finally, arguments cannot have type :default or :boolean but can be
# optional (supplying :optional => :true or :required => false), although
# you cannot have a required argument after a non-required argument. If you
# try it, an error is raised.

# puts "diagnostic output" if options[:verbose]
# Kernel.exec(*args)

# Here +exec+ can be called with +--verbose+ to get diagnostic output,
# e.g.:
#
# $ thor exec --verbose echo foo
# diagnostic output
# foo
#
# But if +--verbose+ is given after +echo+, it is passed to +echo+ instead:

# Bundler::URI is a module providing classes to handle Uniform Resource Identifiers
# (RFC2396[http://tools.ietf.org/html/rfc2396]).
#
# == Features
#
# * Uniform way of handling URIs.
# * Flexibility to introduce custom Bundler::URI schemes.
# * Flexibility to have an alternate Bundler::URI::Parser (or just different patterns
# and regexp's).
#
# == Basic example
#
# require 'bundler/vendor/uri/lib/uri'
#
# uri = Bundler::URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
# #=> #<Bundler::URI::HTTP http://foo.com/posts?id=30&limit=5#time=1305298413>
#
# uri.scheme #=> "http"
# uri.host #=> "foo.com"
# uri.path #=> "/posts"
# uri.query #=> "id=30&limit=5"
# uri.fragment #=> "time=1305298413"
#
# uri.to_s #=> "http://foo.com/posts?id=30&limit=5#time=1305298413"
#
# == Adding custom URIs
#
# module Bundler::URI
# class RSYNC < Generic
# DEFAULT_PORT = 873
# end
# @@schemes['RSYNC'] = RSYNC
# end
# #=> Bundler::URI::RSYNC
#
# Bundler::URI.scheme_list
# #=> {"FILE"=>Bundler::URI::File, "FTP"=>Bundler::URI::FTP, "HTTP"=>Bundler::URI::HTTP,
# # "HTTPS"=>Bundler::URI::HTTPS, "LDAP"=>Bundler::URI::LDAP, "LDAPS"=>Bundler::URI::LDAPS,
# # "MAILTO"=>Bundler::URI::MailTo, "RSYNC"=>Bundler::URI::RSYNC}
#
# uri = Bundler::URI("rsync://rsync.foo.com")
# #=> #<Bundler::URI::RSYNC rsync://rsync.foo.com>

#
# Bundler::URI::Parser.new([opts])
#
# == Args
#
# The constructor accepts a hash as options for parser.
# Keys of options are pattern names of Bundler::URI components
# and values of options are pattern strings.
# The constructor generates set of regexps for parsing URIs.
#
# You can use the following keys:
#
# * :ESCAPED (Bundler::URI::PATTERN::ESCAPED in default)
# * :UNRESERVED (Bundler::URI::PATTERN::UNRESERVED in default)
# * :DOMLABEL (Bundler::URI::PATTERN::DOMLABEL in default)
# * :TOPLABEL (Bundler::URI::PATTERN::TOPLABEL in default)
# * :HOSTNAME (Bundler::URI::PATTERN::HOSTNAME in default)
#
# == Examples
#
# p = Bundler::URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})")
# u = p.parse("http://example.jp/%uABCD") #=> #<Bundler::URI::HTTP http://example.jp/%uABCD>
# Bundler::URI.parse(u.to_s) #=> raises Bundler::URI::InvalidURIError
#
# s = "http://example.com/ABCD"
# u1 = p.parse(s) #=> #<Bundler::URI::HTTP http://example.com/ABCD>

# uri = Bundler::URI::HTTP.build([nil, "www.example.com", nil, "/path",

#--
# tsort.rb - provides a module for topological sorting and strongly connected components.
#++
#
#
# TSort implements topological sorting using Tarjan's algorithm for
# strongly connected components.
#
# TSort is designed to be able to be used with any object which can be
# interpreted as a directed graph.
#
# TSort requires two methods to interpret an object as a graph,
# tsort_each_node and tsort_each_child.
#
# * tsort_each_node is used to iterate for all nodes over a graph.
# * tsort_each_child is used to iterate for child nodes of a given node.
#
# The equality of nodes are defined by eql? and hash since
# TSort uses Hash internally.
#
# == A Simple Example
#
# The following example demonstrates how to mix the TSort module into an
# existing class (in this case, Hash). Here, we're treating each key in
# the hash as a node in the graph, and so we simply alias the required
# #tsort_each_node method to Hash's #each_key method. For each key in the
# hash, the associated value is an array of the node's child nodes. This
# choice in turn leads to our implementation of the required #tsort_each_child
# method, which fetches the array of child nodes and then iterates over that
# array using the user-supplied block.
#
# require 'tsort'
#
# class Hash
# include TSort
# alias tsort_each_node each_key
# def tsort_each_child(node, &block)
# fetch(node).each(&block)
# end
# end
#
# {1=>[2, 3], 2=>[3], 3=>[], 4=>[]}.tsort
# #=> [3, 2, 1, 4]
#
# {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components
# #=> [[4], [2, 3], [1]]
#
# == A More Realistic Example
#
# A very simple `make' like tool can be implemented as follows:
#
# require 'tsort'
#
# class Make
# def initialize
# @dep = {}
# @dep.default = []
# end
#
# def rule(outputs, inputs=[], &block)
# triple = [outputs, inputs, block]
# outputs.each {|f| @dep[f] = [triple]}
# @dep[triple] = inputs
# end
#
# def build(target)
# each_strongly_connected_component_from(target) {|ns|
# if ns.length != 1
# fs = ns.delete_if {|n| Array === n}
# raise TSort::Cyclic.new("cyclic dependencies: #{fs.join ', '}")
# end
# n = ns.first
# if Array === n
# outputs, inputs, block = n
# inputs_time = inputs.map {|f| File.mtime f}.max
# begin
# outputs_time = outputs.map {|f| File.mtime f}.min
# rescue Errno::ENOENT
# outputs_time = nil
# end
# if outputs_time == nil ||
# inputs_time != nil && outputs_time <= inputs_time
# sleep 1 if inputs_time != nil && inputs_time.to_i == Time.now.to_i
# block.call
# end
# end
# }
# end
#
# def tsort_each_child(node, &block)
# @dep[node].each(&block)
# end
# include TSort
# end
#
# def command(arg)
# print arg, "\n"
# system arg
# end
#
# m = Make.new
# m.rule(%w[t1]) { command 'date > t1' }
# m.rule(%w[t2]) { command 'date > t2' }
# m.rule(%w[t3]) { command 'date > t3' }
# m.rule(%w[t4], %w[t1 t3]) { command 'cat t1 t3 > t4' }
# m.rule(%w[t5], %w[t4 t2]) { command 'cat t4 t2 > t5' }
# m.build('t5')
#
# == Bugs
#
# * 'tsort.rb' is wrong name because this library uses
# Tarjan's algorithm for strongly connected components.
# Although 'strongly_connected_components.rb' is correct but too long.

# Runs the install procedures for a specific Gemfile.
#
# Firstly, this method will check to see if `Bundler.bundle_path` exists
# and if not then Bundler will create the directory. This is usually the same
# location as RubyGems which typically is the `~/.gem` directory
# unless other specified.
#
# Secondly, it checks if Bundler has been configured to be "frozen".
# Frozen ensures that the Gemfile and the Gemfile.lock file are matching.
# This stops a situation where a developer may update the Gemfile but may not run
# `bundle install`, which leads to the Gemfile.lock file not being correctly updated.
# If this file is not correctly updated then any other developer running
# `bundle install` will potentially not install the correct gems.
#
# Thirdly, Bundler checks if there are any dependencies specified in the Gemfile.
# If there are no dependencies specified then Bundler returns a warning message stating
# so and this method returns.
#
# Fourthly, Bundler checks if the Gemfile.lock exists, and if so
# then proceeds to set up a definition based on the Gemfile and the Gemfile.lock.
# During this step Bundler will also download information about any new gems
# that are not in the Gemfile.lock and resolve any dependencies if needed.
#
# Fifthly, Bundler resolves the dependencies either through a cache of gems or by remote.
# This then leads into the gems being installed, along with stubs for their executables,
# but only if the --binstubs option has been passed or Bundler.options[:bin] has been set
# earlier.
#
# Sixthly, a new Gemfile.lock is created from the installed gems to ensure that the next time
# that a user runs `bundle install` they will receive any updates from this process.
#
# Finally, if the user has specified the standalone flag, Bundler will generate the needed
# require paths and save them in a `setup.rb` file. See `bundle standalone --help` for more
# information.

To resolve this issue:
1. delete the downloaded gem located at: `#{spec.gem_dir}/#{spec.full_name}.gem`
2. run `bundle install`
If you wish to continue installing the downloaded gem, and are certain it does not pose a \

1. run `bundle config set --local disable_checksum_validation true` to turn off checksum verification
2. run `bundle install`

## Our Pledge
We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
* Focusing on what is best not just for us as individuals, but for the overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at <%= config[:email] %>. All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series of actions.
**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within the community.

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/<%= config[:namespaced_path] %>`. To experiment with that code, run `bin/console` for an interactive prompt.
TODO: Delete this and the text above, and describe your gem
## Installation
Add this line to your application's Gemfile:
```ruby
gem '<%= config[:name] %>'
```
And then execute:
$ bundle install
Or install it yourself as:
$ gem install <%= config[:name] %>
## Usage
TODO: Write usage instructions here
## Development
After checking out the repo, run `bin/setup` to install dependencies.<% if config[:test] %> Then, run `rake <%= config[:test].sub('mini', '').sub('rspec', 'spec') %>` to run the tests.<% end %> You can also run `bin/console` for an interactive prompt that will allow you to experiment.<% if config[:bin] %> Run `bundle exec <%= config[:name] %>` to use the gem in this directory, ignoring other installed copies of this gem.<% end %>
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).

##
# RDoc produces documentation for Ruby source files by parsing the source and
# extracting the definition for classes, modules, methods, includes and
# requires. It associates these with optional documentation contained in an
# immediately preceding comment block then renders the result using an output
# formatter.
#
# For a simple introduction to writing or generating documentation using RDoc
# see the README.
#
# == Roadmap
#
# If you think you found a bug in RDoc see CONTRIBUTING@Bugs
#
# If you want to use RDoc to create documentation for your Ruby source files,
# see RDoc::Markup and refer to <tt>rdoc --help</tt> for command line usage.
#
# If you want to set the default markup format see
# RDoc::Markup@Supported+Formats
#
# If you want to store rdoc configuration in your gem (such as the default
# markup format) see RDoc::Options@Saved+Options
#
# If you want to write documentation for Ruby files see RDoc::Parser::Ruby
#
# If you want to write documentation for extensions written in C see
# RDoc::Parser::C
#
# If you want to generate documentation using <tt>rake</tt> see RDoc::Task.
#
# If you want to drive RDoc programmatically, see RDoc::RDoc.
#
# If you want to use the library to format text blocks into HTML or other
# formats, look at RDoc::Markup.
#
# If you want to make an RDoc plugin such as a generator or directive handler
# see RDoc::RDoc.
#
# If you want to write your own output generator see RDoc::Generator.
#
# If you want an overview of how RDoc works see CONTRIBUTING

##
# RDoc uses generators to turn parsed source code in the form of an
# RDoc::CodeObject tree into some form of output. RDoc comes with the HTML
# generator RDoc::Generator::Darkfish and an ri data generator
# RDoc::Generator::RI.
#
# == Registering a Generator
#
# Generators are registered by calling RDoc::RDoc.add_generator with the class
# of the generator:
#
# class My::Awesome::Generator
# RDoc::RDoc.add_generator self
# end
#
# == Adding Options to +rdoc+
#
# Before option processing in +rdoc+, RDoc::Options will call ::setup_options
# on the generator class with an RDoc::Options instance. The generator can
# use RDoc::Options#option_parser to add command-line options to the +rdoc+
# tool. See RDoc::Options@Custom+Options for an example and see OptionParser
# for details on how to add options.
#
# You can extend the RDoc::Options instance with additional accessors for your
# generator.
#
# == Generator Instantiation
#
# After parsing, RDoc::RDoc will instantiate a generator by calling
# #initialize with an RDoc::Store instance and an RDoc::Options instance.
#
# The RDoc::Store instance holds documentation for parsed source code. In
# RDoc 3 and earlier the RDoc::TopLevel class held this data. When upgrading
# a generator from RDoc 3 and earlier you should only need to replace
# RDoc::TopLevel with the store instance.
#
# RDoc will then call #generate on the generator instance. You can use the
# various methods on RDoc::Store and in the RDoc::CodeObject tree to create
# your desired output format.

All class names may be abbreviated to their minimum unambiguous form.
If a name is ambiguous, all valid options will be listed.
A '.' matches either class or instance methods, while #method
matches only instance and ::method matches only class methods.
README and other files may be displayed by prefixing them with the gem name
they're contained in. If the gem name is followed by a ':' all files in the
gem will be shown. The file name extension may be omitted where it is
unambiguous.
For example:
#{opt.program_name} Fil
#{opt.program_name} File
#{opt.program_name} File.new
#{opt.program_name} zip
#{opt.program_name} rdoc:README
Note that shell quoting or escaping may be required for method names
containing punctuation:
#{opt.program_name} 'Array.[]'
#{opt.program_name} compact\\!
To see the default directories #{opt.program_name} will search, run:
#{opt.program_name} --list-doc-dirs
Specifying the --system, --site, --home, --gems, or --doc-dir options
will limit ri to searching only the specified directories.
ri options may be set in the RI environment variable.

# RDoc::Markdown as described by the [markdown syntax][syntax].
#
# To choose Markdown as your only default format see
# RDoc::Options@Saved+Options for instructions on setting up a `.doc_options`
# file to store your project default.
#
# ## Usage
#
# Here is a brief example of using this parse to read a markdown file by hand.
#
# data = File.read("README.md")
# formatter = RDoc::Markup::ToHtml.new(RDoc::Options.new, nil)

#

#
# ## Extensions
#
# The following markdown extensions are supported by the parser, but not all
# are used in RDoc output by default.
#
# ### RDoc
#
# The RDoc Markdown parser has the following built-in behaviors that cannot be
# disabled.
#
# Underscores embedded in words are never interpreted as emphasis. (While the
# [markdown dingus][dingus] emphasizes in-word underscores, neither the
# Markdown syntax nor MarkdownTest mention this behavior.)
#
# For HTML output, RDoc always auto-links bare URLs.
#
# ### Break on Newline
#
# The break_on_newline extension converts all newlines into hard line breaks
# as in [Github Flavored Markdown][GFM]. This extension is disabled by
# default.
#
# ### CSS
#
# The #css extension enables CSS blocks to be included in the output, but they
# are not used for any built-in RDoc output format. This extension is disabled
# by default.
#
# Example:
#
# <style type="text/css">
# h1 { font-size: 3em }
# </style>
#
# ### Definition Lists
#
# The definition_lists extension allows definition lists using the [PHP
# Markdown Extra syntax][PHPE], but only one label and definition are supported
# at this time. This extension is enabled by default.
#
# Example:
#
# ```
# cat
# : A small furry mammal
# that seems to sleep a lot
#
# ant
# : A little insect that is known
# to enjoy picnics
#
# ```
#
# Produces:
#
# cat
# : A small furry mammal
# that seems to sleep a lot
#
# ant
# : A little insect that is known
# to enjoy picnics
#
# ### Strike
#
# Example:
#
# ```
# This is ~~striked~~.
# ```
#
# Produces:
#
# This is ~~striked~~.
#
# ### Github
#
# The #github extension enables a partial set of [Github Flavored Markdown]
# [GFM]. This extension is enabled by default.
#
# Supported github extensions include:
#
# #### Fenced code blocks
#
# Use ` ``` ` around a block of code instead of indenting it four spaces.
#
# #### Syntax highlighting
#
# Use ` ``` ruby ` as the start of a code fence to add syntax highlighting.
# (Currently only `ruby` syntax is supported).
#
# ### HTML
#
# Enables raw HTML to be included in the output. This extension is enabled by
# default.
#
# Example:
#
# <table>
# ...
# </table>
#
# ### Notes
#
# The #notes extension enables footnote support. This extension is enabled by
# default.
#
# Example:
#
# Here is some text[^1] including an inline footnote ^[for short footnotes]
#
# ...
#
# [^1]: With the footnote text down at the bottom
#
# Produces:
#
# Here is some text[^1] including an inline footnote ^[for short footnotes]
#
# [^1]: With the footnote text down at the bottom
#
# ## Limitations
#
# * Link titles are not used
# * Footnotes are collapsed into a single paragraph

# RDoc::Parser::C attempts to parse C extension files. It looks for

# +rb_define_method+ and so on. It tries to find the corresponding
# C source for the methods and extract comments, but if we fail
# we don't worry too much.
#
# The comments associated with a Ruby method are extracted from the C
# comment block associated with the routine that _implements_ that
# method, that is to say the method whose name is given in the
# +rb_define_method+ call. For example, you might write:
#
# /*
# * Returns a new array that is a one-dimensional flattening of this
# * array (recursively). That is, for every element that is an array,
# * extract its elements into the new array.
# *
# * s = [ 1, 2, 3 ] #=> [1, 2, 3]
# * t = [ 4, 5, 6, [7, 8] ] #=> [4, 5, 6, [7, 8]]
# * a = [ s, t, 9, 10 ] #=> [[1, 2, 3], [4, 5, 6, [7, 8]], 9, 10]
# * a.flatten #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# ...
#
# void
# Init_Array(void)
# {

# rb_define_method(rb_cArray, "flatten", rb_ary_flatten, 0);
#
# Here RDoc will determine from the +rb_define_method+ line that there's a
# method called "flatten" in class Array, and will look for the implementation
# in the method +rb_ary_flatten+. It will then use the comment from that
# method in the HTML output. This method must be in the same source file
# as the +rb_define_method+.
#
# The comment blocks may include special directives:
#
# [Document-class: +name+]
# Documentation for the named class.
#
# [Document-module: +name+]
# Documentation for the named module.
#
# [Document-const: +name+]
# Documentation for the named +rb_define_const+.
#
# Constant values can be supplied on the first line of the comment like so:
#
# /* 300: The highest possible score in bowling */
# rb_define_const(cFoo, "PERFECT", INT2FIX(300));
#
# The value can contain internal colons so long as they are escaped with a \
#
# [Document-global: +name+]
# Documentation for the named +rb_define_global_const+
#
# [Document-variable: +name+]
# Documentation for the named +rb_define_variable+
#
# [Document-method\: +method_name+]
# Documentation for the named method. Use this when the method name is
# unambiguous.
#
# [Document-method\: <tt>ClassName::method_name</tt>]
# Documentation for a singleton method in the given class. Use this when
# the method name alone is ambiguous.
#
# [Document-method\: <tt>ClassName#method_name</tt>]
# Documentation for a instance method in the given class. Use this when the
# method name alone is ambiguous.
#
# [Document-attr: +name+]
# Documentation for the named attribute.
#
# [call-seq: <i>text up to an empty line</i>]
# Because C source doesn't give descriptive names to Ruby-level parameters,
# you need to document the calling sequence explicitly
#
# In addition, RDoc assumes by default that the C method implementing a
# Ruby function is in the same source file as the rb_define_method call.
# If this isn't the case, add the comment:
#
# rb_define_method(....); // in filename
#
# As an example, we might have an extension that defines multiple classes
# in its Init_xxx method. We could document them using
#
# /*
# * Document-class: MyClass
# *
# * Encapsulate the writing and reading of the configuration
# * file. ...
# */
#
# /*
# * Document-method: read_value

# * constants
# * aliases
# * private, public, protected
# * private_class_function, public_class_function

# * module_function

#
# == Method Arguments
#
#--
# NOTE: I don't think this works, needs tests, remove the paragraph following
# this block when known to work
#
# The parser extracts the arguments from the method definition. You can
# override this with a custom argument definition using the :args: directive:
#
# ##
# # This method tries over and over until it is tired
#
# def go_go_go(thing_to_try, tries = 10) # :args: thing_to_try
# puts thing_to_try
# go_go_go thing_to_try, tries - 1
# end
#
# If you have a more-complex set of overrides you can use the :call-seq:
# directive:
#++
#
# The parser extracts the arguments from the method definition. You can
# override this with a custom argument definition using the :call-seq:
# directive:
#
# ##
# # This method can be called with a range or an offset and length
# #
# # :call-seq:
# # my_method(Range)
# # my_method(offset, length)
#
# def my_method(*args)
# end
#
# The parser extracts +yield+ expressions from method bodies to gather the
# yielded argument names. If your method manually calls a block instead of
# yielding or you want to override the discovered argument names use
# the :yields: directive:
#
# ##
# # My method is awesome
#
# def my_method(&block) # :yields: happy, times
# block.call 1, 2
# end
#
# == Metaprogrammed Methods
#
# To pick up a metaprogrammed method, the parser looks for a comment starting
# with '##' before an identifier:
#
# ##
# # This is a meta-programmed method!
#
# add_my_method :meta_method, :arg1, :arg2
#
# The parser looks at the token after the identifier to determine the name, in
# this example, :meta_method. If a name cannot be found, a warning is printed
# and 'unknown is used.
#
# You can force the name of a method using the :method: directive:
#
# ##
# # :method: some_method!
#
# By default, meta-methods are instance methods. To indicate that a method is
# a singleton method instead use the :singleton-method: directive:
#
# ##
# # :singleton-method:
#
# You can also use the :singleton-method: directive with a name:
#
# ##
# # :singleton-method: some_method!
#
# You can define arguments for metaprogrammed methods via either the
# :call-seq:, :arg: or :args: directives.
#
# Additionally you can mark a method as an attribute by
# using :attr:, :attr_reader:, :attr_writer: or :attr_accessor:. Just like
# for :method:, the name is optional.
#
# ##
# # :attr_reader: my_attr_name
#
# == Hidden methods and attributes
#
# You can provide documentation for methods that don't appear using
# the :method:, :singleton-method: and :attr: directives:
#
# ##
# # :attr_writer: ghost_writer
# # There is an attribute here, but you can't see it!
#
# ##
# # :method: ghost_method
# # There is a method here, but you can't see it!
#
# ##
# # this is a comment for a regular method
#
# def regular_method() end
#
# Note that by default, the :method: directive will be ignored if there is a
# standard rdocable item following it.

# The JsonIndex generator is designed to complement an HTML generator and
# produces a JSON search index. This generator is derived from sdoc by
# Vladimir Kolesnikov and contains verbatim code written by him.
#
# This generator is designed to be used with a regular HTML generator:
#
# class RDoc::Generator::Darkfish
# def initialize options
# # ...
# @base_dir = Pathname.pwd.expand_path
#
# @json_index = RDoc::Generator::JsonIndex.new self, options
# end
#
# def generate
# # ...
# @json_index.generate
# end
# end
#
# == Index Format
#
# The index is output as a JSON file assigned to the global variable
# +search_data+. The structure is:
#
# var search_data = {
# "index": {
# "searchIndex":
# ["a", "b", ...],
# "longSearchIndex":
# ["a", "a::b", ...],
# "info": [
# ["A", "A", "A.html", "", ""],
# ["B", "A::B", "A::B.html", "", ""],
# ...
# ]
# }
# }
#
# The same item is described across the +searchIndex+, +longSearchIndex+ and
# +info+ fields. The +searchIndex+ field contains the item's short name, the
# +longSearchIndex+ field contains the full_name (when appropriate) and the
# +info+ field contains the item's name, full_name, path, parameters and a
# snippet of the item's comment.

# Generates a POT file.
#
# Here is a translator work flow with the generator.
#
# == Create .pot
#
# You create .pot file by pot formatter:
#
# % rdoc --format pot
#
# It generates doc/rdoc.pot.
#
# == Create .po
#
# You create .po file from doc/rdoc.pot. This operation is needed only
# the first time. This work flow assumes that you are a translator
# for Japanese.
#
# You create locale/ja/rdoc.po from doc/rdoc.pot. You can use msginit
# provided by GNU gettext or rmsginit provided by gettext gem. This
# work flow uses gettext gem because it is more portable than GNU
# gettext for Rubyists. Gettext gem is implemented by pure Ruby.
#
# % gem install gettext
# % mkdir -p locale/ja
# % rmsginit --input doc/rdoc.pot --output locale/ja/rdoc.po --locale ja
#
# Translate messages in .po
#
# You translate messages in .po by a PO file editor. po-mode.el exists
# for Emacs users. There are some GUI tools such as GTranslator.
# There are some Web services such as POEditor and Tansifex. You can
# edit by your favorite text editor because .po is a text file.
# Generate localized documentation
#
# You can generate localized documentation with locale/ja/rdoc.po:
#
# % rdoc --locale ja
#
# You can find documentation in Japanese in doc/. Yay!
#
# == Update translation
#
# You need to update translation when your application is added or
# modified messages.
#
# You can update .po by the following command lines:
#
# % rdoc --format pot
# % rmsgmerge --update locale/ja/rdoc.po doc/rdoc.pot
#
# You edit locale/ja/rdoc.po to translate new messages.

*
* PREAMBLE
* The goals of the Open Font License (OFL) are to stimulate worldwide
* development of collaborative font projects, to support the font creation
* efforts of academic and linguistic communities, and to provide a free and

* with others.
*
* The OFL allows the licensed fonts to be used, studied, modified and
* redistributed freely as long as they are not sold by themselves. The
* fonts, including any derivative works, can be bundled, embedded,
* redistributed and/or sold with any software provided that any reserved
* names are not used by derivative works. The fonts and derivatives,
* however, cannot be released under any other type of license. The
* requirement for fonts to remain under this license does not apply
* to any document created using the fonts or their derivatives.
*

*
* 3) No Modified Version of the Font Software may use the Reserved Font

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2013-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

Licensed under the SIL Open Font License, Version 1.1.LatoRegulartyPolandLukaszDziedzic: Lato Regular: 2013Lato RegularVersion 1.105; Western+Polish opensourceLato-RegularLato is a trademark of tyPoland Lukasz Dziedzic.tyPoland Lukasz DziedzicLukasz DziedzicLato is a sanserif typeface family designed in the Summer 2010 by Warsaw-based designer Lukasz Dziedzic ("Lato" means "Summer" in Polish). It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2010-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2010-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

It tries to carefully balance some potentially conflicting priorities: it should seem quite "transparent" when used in body text but would display some original traits when used in larger sizes. The classical proportions, particularly visible in the uppercase, give the letterforms familiar harmony and elegance. At the same time, its sleek sanserif look makes evident the fact that Lato was designed in 2010, even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness.http://www.typoland.com/http://www.typoland.com/designers/Lukasz_Dziedzic/Copyright (c) 2013-2013 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato".

# RDoc::Task creates the following rake tasks to generate and clean up RDoc
# output:
#
# [rdoc]
# Main task for this RDoc task.
#
# [clobber_rdoc]
# Delete all the rdoc files. This target is automatically added to the main
# clobber target.
#
# [rerdoc]
# Rebuild the rdoc files from scratch, even if they are not out of date.
#
# Simple Example:
#
# require 'rdoc/task'
#
# RDoc::Task.new do |rdoc|
# rdoc.main = "README.rdoc"
# rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
# end
#
# The +rdoc+ object passed to the block is an RDoc::Task object. See the
# attributes list for the RDoc::Task class for available customization options.
#
# == Specifying different task names
#
# You may wish to give the task a different name, such as if you are
# generating two sets of documentation. For instance, if you want to have a
# development set of documentation including private methods:
#
# require 'rdoc/task'
#
# RDoc::Task.new :rdoc_dev do |rdoc|
# rdoc.main = "README.doc"
# rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
# rdoc.options << "--all"
# end
#
# The tasks would then be named :<em>rdoc_dev</em>,
# :clobber_<em>rdoc_dev</em>, and :re<em>rdoc_dev</em>.
#
# If you wish to have completely different task names, then pass a Hash as
# first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
# <tt>:rerdoc</tt> options, you can customize the task names to your liking.
#
# For example:
#
# require 'rdoc/task'
#
# RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean",
# :rerdoc => "rdoc:force")
#
# This will create the tasks <tt>:rdoc</tt>, <tt>:rdoc:clean</tt> and
# <tt>:rdoc:force</tt>.

# RDoc::Options handles the parsing and storage of options
#
# == Saved Options
#
# You can save some options like the markup format in the
# <tt>.rdoc_options</tt> file in your gem. The easiest way to do this is:
#
# rdoc --markup tomdoc --write-options
#
# Which will automatically create the file and fill it with the options you
# specified.
#
# The following options will not be saved since they interfere with the user's
# preferences or with the normal operation of RDoc:
#
# * +--coverage-report+
# * +--dry-run+
# * +--encoding+
# * +--force-update+
# * +--format+
# * +--pipe+
# * +--quiet+
# * +--template+
# * +--verbose+
#
# == Custom Options
#
# Generators can hook into RDoc::Options to add generator-specific command
# line options.
#
# When <tt>--format</tt> is encountered in ARGV, RDoc calls ::setup_options on
# the generator class to add extra options to the option parser. Options for
# custom generators must occur after <tt>--format</tt>. <tt>rdoc --help</tt>
# will list options for all installed generators.
#
# Example:
#
# class RDoc::Generator::Spellcheck
# RDoc::RDoc.add_generator self
#
# def self.setup_options rdoc_options
# op = rdoc_options.option_parser
#
# op.on('--spell-dictionary DICTIONARY',
# RDoc::Options::Path) do |dictionary|
# rdoc_options.spell_dictionary = dictionary
# end
# end
# end
#
# Of course, RDoc::Options does not respond to +spell_dictionary+ by default
# so you will need to add it:
#
# class RDoc::Options
#
# ##
# # The spell dictionary used by the spell-checking plugin.
#
# attr_accessor :spell_dictionary
#
# end
#
# == Option Validators
#
# OptionParser validators will validate and cast user input values. In
# addition to the validators that ship with OptionParser (String, Integer,
# Float, TrueClass, FalseClass, Array, Regexp, Date, Time, URI, etc.),
# RDoc::Options adds Path, PathArray and Template.
class RDoc::Options
##
# The deprecated options.

Usage: #{opt.program_name} [options] [names...]
Files are parsed, and the information they contain collected, before any
output is produced. This allows cross references between all files to be
resolved. If a name is a directory, it is traversed. If no names are
specified, all Ruby files in the current directory (and subdirectories) are
processed.
How RDoc generates output depends on the output formatter being used, and on
the options you give.
Options can be specified via the RDOCOPT environment variable, which
functions similar to the RUBYOPT environment variable for ruby.
$ export RDOCOPT="--show-hash"
will make rdoc show hashes in method links by default. Command-line options
always will override those in RDOCOPT.
Available formatters:
#{generator_descriptions}
RDoc understands the following file formats:

# :markup: tomdoc
# A parser for TomDoc based on TomDoc 1.0.0-rc1 (02adef9b5a)
#
# The TomDoc specification can be found at:
#
# http://tomdoc.org
#
# The latest version of the TomDoc specification can be found at:
#
# https://github.com/mojombo/tomdoc/blob/master/tomdoc.md
#
# To choose TomDoc as your only default format see RDoc::Options@Saved+Options
# for instructions on setting up a <code>.rdoc_options</code> file to store
# your project default.
#
# There are a few differences between this parser and the specification. A
# best-effort was made to follow the specification as closely as possible but
# some choices to deviate were made.
#
# A future version of RDoc will warn when a MUST or MUST NOT is violated and
# may warn when a SHOULD or SHOULD NOT is violated. RDoc will always try
# to emit documentation even if given invalid TomDoc.
#
# Here are some implementation choices this parser currently makes:
#
# This parser allows rdoc-style inline markup but you should not depended on
# it.
#
# This parser allows a space between the comment and the method body.
#
# This parser does not require the default value to be described for an
# optional argument.
#
# This parser does not examine the order of sections. An Examples section may
# precede the Arguments section.
#
# This class is documented in TomDoc format. Since this is a subclass of the
# RDoc markup parser there isn't much to see here, unfortunately.

# RDoc::Markup parses plain text documents and attempts to decompose them into
# their constituent parts. Some of these parts are high-level: paragraphs,
# chunks of verbatim text, list entries and the like. Other parts happen at
# the character level: a piece of bold text, a word in code font. This markup
# is similar in spirit to that used on WikiWiki webs, where folks create web
# pages using a simple set of formatting rules.
#
# RDoc::Markup and other markup formats do no output formatting, this is
# handled by the RDoc::Markup::Formatter subclasses.
#
# = Supported Formats
#
# Besides the RDoc::Markup format, the following formats are built in to RDoc:
#
# markdown::
# The markdown format as described by
# http://daringfireball.net/projects/markdown/. See RDoc::Markdown for
# details on the parser and supported extensions.
# rd::
# The rdtool format. See RDoc::RD for details on the parser and format.
# tomdoc::
# The TomDoc format as described by http://tomdoc.org/. See RDoc::TomDoc
# for details on the parser and supported extensions.
#
# You can choose a markup format using the following methods:
#
# per project::
# If you build your documentation with rake use RDoc::Task#markup.
#
# If you build your documentation by hand run:
#
# rdoc --markup your_favorite_format --write-options
#
# and commit <tt>.rdoc_options</tt> and ship it with your packaged gem.
# per file::
# At the top of the file use the <tt>:markup:</tt> directive to set the
# default format for the rest of the file.
# per comment::
# Use the <tt>:markup:</tt> directive at the top of a comment you want
# to write in a different format.
#
# = RDoc::Markup
#
# RDoc::Markup is extensible at runtime: you can add \new markup elements to
# be recognized in the documents that RDoc::Markup parses.
#
# RDoc::Markup is intended to be the basis for a family of tools which share
# the common requirement that simple, plain-text should be rendered in a
# variety of different output formats and media. It is envisaged that
# RDoc::Markup could be the basis for formatting RDoc style comment blocks,
# Wiki entries, and online FAQs.
#
# == Synopsis
#
# This code converts +input_string+ to HTML. The conversion takes place in
# the +convert+ method, so you can use the same RDoc::Markup converter to
# convert multiple input strings.
#
# require 'rdoc'
#
# h = RDoc::Markup::ToHtml.new(RDoc::Options.new)
#
# puts h.convert(input_string)
#
# You can extend the RDoc::Markup parser to recognize new markup
# sequences, and to add regexp handling. Here we make WikiWords significant to
# the parser, and also make the sequences {word} and \<no>text...</no> signify
# strike-through text. We then subclass the HTML output class to deal
# with these:
#
# require 'rdoc'
#
# class WikiHtml < RDoc::Markup::ToHtml
# def handle_regexp_WIKIWORD(target)
# "<font color=red>" + target.text + "</font>"
# end
# end
#
# markup = RDoc::Markup.new
# markup.add_word_pair("{", "}", :STRIKE)
# markup.add_html("no", :STRIKE)
#
# markup.add_regexp_handling(/\b([A-Z][a-z]+[A-Z]\w+)/, :WIKIWORD)
#
# wh = WikiHtml.new RDoc::Options.new, markup
# wh.add_tag(:STRIKE, "<strike>", "</strike>")
#
# puts "<body>#{wh.convert ARGF.read}</body>"
#
# == Encoding
#
# Where Encoding support is available, RDoc will automatically convert all
# documents to the same output encoding. The output encoding can be set via
# RDoc::Options#encoding and defaults to Encoding.default_external.
#
# = \RDoc Markup Reference
#
# == Block Markup
#
# === Paragraphs and Verbatim
#
# The markup engine looks for a document's natural left margin. This is
# used as the initial margin for the document.
#
# Consecutive lines starting at this margin are considered to be a
# paragraph. Empty lines separate paragraphs.
#
# Any line that starts to the right of the current margin is treated
# as verbatim text. This is useful for code listings:
#
# 3.times { puts "Ruby" }
#
# In verbatim text, two or more blank lines are collapsed into one,
# and trailing blank lines are removed:
#
# This is the first line
#
#
# This is the second non-blank line,
# after 2 blank lines in the source markup.
#
#
# There were two trailing blank lines right above this paragraph, that
# have been removed. In addition, the verbatim text has been shifted
# left, so the amount of indentation of verbatim text is unimportant.
#
# For HTML output RDoc makes a small effort to determine if a verbatim section
# contains Ruby source code. If so, the verbatim block will be marked up as
# HTML. Triggers include "def", "class", "module", "require", the "hash
# rocket"# (=>) or a block call with a parameter.
#
# === Headers
#
# A line starting with an equal sign (=) is treated as a
# heading. Level one headings have one equals sign, level two headings
# have two, and so on until level six, which is the maximum
# (seven hyphens or more result in a level six heading).
#
# For example, the above header was obtained with:
#
# === Headers
#
# In HTML output headers have an id matching their name. The above example's
# HTML is:
#
# <h3 id="label-Headers">Headers</h3>
#
# If a heading is inside a method body the id will be prefixed with the
# method's id. If the above header where in the documentation for a method
# such as:
#
# ##
# # This method does fun things
# #
# # = Example
# #
# # Example of fun things goes here ...
#
# def do_fun_things
# end
#
# The header's id would be:
#
# <h1 id="method-i-do_fun_things-label-Example">Example</h1>
#
# The label can be linked-to using <tt>SomeClass@Headers</tt>. See
# {Links}[RDoc::Markup@Links] for further details.
#
# === Rules
#
# A line starting with three or more hyphens (at the current indent)
# generates a horizontal rule.
#
# ---
#
# produces:
#
# ---
#
# === Simple Lists
#
# If a paragraph starts with a "*", "-", "<digit>." or "<letter>.",
# then it is taken to be the start of a list. The margin is increased to be
# the first non-space following the list start flag. Subsequent lines
# should be indented to this new margin until the list ends. For example:
#
# * this is a list with three paragraphs in
# the first item. This is the first paragraph.
#
# And this is the second paragraph.
#
# 1. This is an indented, numbered list.
# 2. This is the second item in that list
#
# This is the third conventional paragraph in the
# first list item.
#
# * This is the second item in the original list
#
# produces:
#
# * this is a list with three paragraphs in
# the first item. This is the first paragraph.
#
# And this is the second paragraph.
#
# 1. This is an indented, numbered list.
# 2. This is the second item in that list
#
# This is the third conventional paragraph in the
# first list item.
#
# * This is the second item in the original list
#
# === Labeled Lists
#
# You can also construct labeled lists, sometimes called description
# or definition lists. Do this by putting the label in square brackets
# and indenting the list body:
#
# [cat] a small furry mammal
# that seems to sleep a lot
#
# [ant] a little insect that is known
# to enjoy picnics
#
# produces:
#
# [cat] a small furry mammal
# that seems to sleep a lot
#
# [ant] a little insect that is known
# to enjoy picnics
#
# If you want the list bodies to line up to the left of the labels,
# use two colons:
#
# cat:: a small furry mammal
# that seems to sleep a lot
#
# ant:: a little insect that is known
# to enjoy picnics
#
# produces:
#
# cat:: a small furry mammal
# that seems to sleep a lot
#
# ant:: a little insect that is known
# to enjoy picnics
#
# Notice that blank lines right after the label are ignored in labeled lists:
#
# [one]
#
# definition 1
#
# [two]
#
# definition 2
#
# produces the same output as
#
# [one] definition 1
# [two] definition 2
#
#
# === Lists and Verbatim
#
# If you want to introduce a verbatim section right after a list, it has to be
# less indented than the list item bodies, but more indented than the list
# label, letter, digit or bullet. For instance:
#
# * point 1
#
# * point 2, first paragraph
#
# point 2, second paragraph
# verbatim text inside point 2
# point 2, third paragraph
# verbatim text outside of the list (the list is therefore closed)
# regular paragraph after the list
#
# produces:
#
# * point 1
#
# * point 2, first paragraph
#
# point 2, second paragraph
# verbatim text inside point 2
# point 2, third paragraph
# verbatim text outside of the list (the list is therefore closed)
# regular paragraph after the list
#
# == Text Markup
#
# === Bold, Italic, Typewriter Text
#
# You can use markup within text (except verbatim) to change the
# appearance of parts of that text. Out of the box, RDoc::Markup
# supports word-based and general markup.
#
# Word-based markup uses flag characters around individual words:
#
# <tt>\*_word_\*</tt>:: displays _word_ in a *bold* font
# <tt>\__word_\_</tt>:: displays _word_ in an _emphasized_ font
# <tt>\+_word_\+</tt>:: displays _word_ in a +code+ font
#
# General markup affects text between a start delimiter and an end
# delimiter. Not surprisingly, these delimiters look like HTML markup.
#
# <tt>\<b>_text_</b></tt>:: displays _text_ in a *bold* font
# <tt>\<em>_text_</em></tt>:: displays _text_ in an _emphasized_ font
# (alternate tag: <tt>\<i></tt>)
# <tt>\<tt>_text_\</tt></tt>:: displays _text_ in a +code+ font
# (alternate tag: <tt>\<code></tt>)
#
# Unlike conventional Wiki markup, general markup can cross line
# boundaries. You can turn off the interpretation of markup by
# preceding the first character with a backslash (see <i>Escaping
# Text Markup</i>, below).
#
# === Links
#
# Links to starting with +http:+, +https:+, +mailto:+, +ftp:+ or +www.+
# are recognized. An HTTP url that references an external image is converted
# into an inline image element.
#
# Classes and methods will be automatically linked to their definition. For
# example, <tt>RDoc::Markup</tt> will link to this documentation. By default
# methods will only be automatically linked if they contain an <tt>_</tt> (all
# methods can be automatically linked through the <tt>--hyperlink-all</tt>
# command line option).
#
# Single-word methods can be linked by using the <tt>#</tt> character for
# instance methods or <tt>::</tt> for class methods. For example,
# <tt>#convert</tt> links to #convert. A class or method may be combined like
# <tt>RDoc::Markup#convert</tt>.
#
# A heading inside the documentation can be linked by following the class
# or method by an <tt>@</tt> then the heading name.
# <tt>RDoc::Markup@Links</tt> will link to this section like this:
# RDoc::Markup@Links. Spaces in headings with multiple words must be escaped
# with <tt>+</tt> like <tt>RDoc::Markup@Escaping+Text+Markup</tt>.
# Punctuation and other special characters must be escaped like CGI.escape.
#
# The <tt>@</tt> can also be used to link to sections. If a section and a
# heading share the same name the section is preferred for the link.
#
# Links can also be of the form <tt>label[url]</tt>, in which case +label+ is
# used in the displayed text, and +url+ is used as the target. If +label+
# contains multiple words, put it in braces: <tt>{multi word label}[url]</tt>.
# The +url+ may be an +http:+-type link or a cross-reference to a class,
# module or method with a label.
#
# Links with the <code>rdoc-image:</code> scheme will create an image tag for
# HTML output. Only fully-qualified URLs are supported.
#
# Links with the <tt>rdoc-ref:</tt> scheme will link to the referenced class,
# module, method, file, etc. If the referenced item is does not exist
# no link will be generated and <tt>rdoc-ref:</tt> will be removed from the
# resulting text.
#
# Links starting with <tt>rdoc-label:label_name</tt> will link to the
# +label_name+. You can create a label for the current link (for
# bidirectional links) by supplying a name for the current link like
# <tt>rdoc-label:label-other:label-mine</tt>.
#
# Links starting with +link:+ refer to local files whose path is relative to
# the <tt>--op</tt> directory. Use <tt>rdoc-ref:</tt> instead of
# <tt>link:</tt> to link to files generated by RDoc as the link target may
# be different across RDoc generators.
#
# Example links:
#
# https://github.com/ruby/rdoc
# mailto:user@example.com
# {RDoc Documentation}[http://rdoc.rubyforge.org]
# {RDoc Markup}[rdoc-ref:RDoc::Markup]
#
# === Escaping Text Markup
#
# Text markup can be escaped with a backslash, as in \<tt>, which was obtained
# with <tt>\\<tt></tt>. Except in verbatim sections and between \<tt> tags,
# to produce a backslash you have to double it unless it is followed by a
# space, tab or newline. Otherwise, the HTML formatter will discard it, as it
# is used to escape potential links:
#
# * The \ must be doubled if not followed by white space: \\.
# * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
# * This is a link to {ruby-lang}[www.ruby-lang.org].
# * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org].
# * This will not be linked to \RDoc::RDoc#document
#
# generates:
#
# * The \ must be doubled if not followed by white space: \\.
# * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
# * This is a link to {ruby-lang}[www.ruby-lang.org]
# * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org]
# * This will not be linked to \RDoc::RDoc#document
#
# Inside \<tt> tags, more precisely, leading backslashes are removed only if
# followed by a markup character (<tt><*_+</tt>), a backslash, or a known link
# reference (a known class or method). So in the example above, the backslash
# of <tt>\S</tt> would be removed if there was a class or module named +S+ in
# the current context.
#
# This behavior is inherited from RDoc version 1, and has been kept for
# compatibility with existing RDoc documentation.
#
# === Conversion of characters
#
# HTML will convert two/three dashes to an em-dash. Other common characters are
# converted as well:
#
# em-dash:: -- or ---
# ellipsis:: ...
#
# single quotes:: 'text' or `text'
# double quotes:: "text" or ``text''
#
# copyright:: (c)
# registered trademark:: (r)
#
# produces:
#
# em-dash:: -- or ---
# ellipsis:: ...
#
# single quotes:: 'text' or `text'
# double quotes:: "text" or ``text''
#
# copyright:: (c)
# registered trademark:: (r)
#
#
# == Documenting Source Code
#
# Comment blocks can be written fairly naturally, either using <tt>#</tt> on
# successive lines of the comment, or by including the comment in
# a <tt>=begin</tt>/<tt>=end</tt> block. If you use the latter form,
# the <tt>=begin</tt> line _must_ be flagged with an +rdoc+ tag:
#
# =begin rdoc
# Documentation to be processed by RDoc.
#
# ...
# =end
#
# RDoc stops processing comments if it finds a comment line starting
# with <tt>--</tt> right after the <tt>#</tt> character (otherwise,
# it will be treated as a rule if it has three dashes or more).
# This can be used to separate external from internal comments,
# or to stop a comment being associated with a method, class, or module.
# Commenting can be turned back on with a line that starts with <tt>++</tt>.
#
# ##
# # Extract the age and calculate the date-of-birth.
# #--
# # FIXME: fails if the birthday falls on February 29th
# #++
# # The DOB is returned as a Time object.
#
# def get_dob(person)
# # ...
# end
#
# Names of classes, files, and any method names containing an underscore or
# preceded by a hash character are automatically linked from comment text to
# their description. This linking works inside the current class or module,
# and with ancestor methods (in included modules or in the superclass).
#
# Method parameter lists are extracted and displayed with the method
# description. If a method calls +yield+, then the parameters passed to yield
# will also be displayed:
#
# def fred
# ...
# yield line, address
#
# This will get documented as:
#
# fred() { |line, address| ... }
#
# You can override this using a comment containing ':yields: ...' immediately
# after the method definition
#
# def fred # :yields: index, position
# # ...
#
# yield line, address
#
# which will get documented as
#
# fred() { |index, position| ... }
#
# +:yields:+ is an example of a documentation directive. These appear
# immediately after the start of the document element they are modifying.
#
# RDoc automatically cross-references words with underscores or camel-case.
# To suppress cross-references, prefix the word with a \ character. To
# include special characters like "<tt>\n</tt>", you'll need to use
# two \ characters in normal text, but only one in \<tt> text:
#
# "\\n" or "<tt>\n</tt>"
#
# produces:
#
# "\\n" or "<tt>\n</tt>"
#
# == Directives
#
# Directives are keywords surrounded by ":" characters.
#
# === Controlling what is documented
#
# [+:nodoc:+ / <tt>:nodoc: all</tt>]
# This directive prevents documentation for the element from
# being generated. For classes and modules, methods, aliases,
# constants, and attributes directly within the affected class or
# module also will be omitted. By default, though, modules and
# classes within that class or module _will_ be documented. This is
# turned off by adding the +all+ modifier.
#
# module MyModule # :nodoc:
# class Input
# end
# end
#
# module OtherModule # :nodoc: all
# class Output
# end
# end
#
# In the above code, only class <tt>MyModule::Input</tt> will be documented.
#
# The +:nodoc:+ directive, like +:enddoc:+, +:stopdoc:+ and +:startdoc:+
# presented below, is local to the current file: if you do not want to
# document a module that appears in several files, specify +:nodoc:+ on each
# appearance, at least once per file.
#
# [+:stopdoc:+ / +:startdoc:+]
# Stop and start adding new documentation elements to the current container.
# For example, if a class has a number of constants that you don't want to
# document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the
# last. If you don't specify a +:startdoc:+ by the end of the container,
# disables documentation for the rest of the current file.
#
# [+:doc:+]
# Forces a method or attribute to be documented even if it wouldn't be
# otherwise. Useful if, for example, you want to include documentation of a
# particular private method.
#
# [+:enddoc:+]
# Document nothing further at the current level: directives +:startdoc:+ and
# +:doc:+ that appear after this will not be honored for the current container
# (file, class or module), in the current file.
#
# [+:notnew:+ / +:not_new:+ / +:not-new:+ ]
# Only applicable to the +initialize+ instance method. Normally RDoc
# assumes that the documentation and parameters for +initialize+ are
# actually for the +new+ method, and so fakes out a +new+ for the class.
# The +:notnew:+ directive stops this. Remember that +initialize+ is private,
# so you won't see the documentation unless you use the +-a+ command line
# option.
#
# === Method arguments
#
# [+:arg:+ or +:args:+ _parameters_]
# Overrides the default argument handling with exactly these parameters.
#
# ##
# # :args: a, b
#
# def some_method(*a)
# end
#
# [+:yield:+ or +:yields:+ _parameters_]
# Overrides the default yield discovery with these parameters.
#
# ##
# # :yields: key, value
#
# def each_thing &block
# @things.each(&block)
# end
#
# [+:call-seq:+]
# Lines up to the next blank line or lines with a common prefix in the
# comment are treated as the method's calling sequence, overriding the
# default parsing of method parameters and yield arguments.
#
# Multiple lines may be used.
#
# # :call-seq:
# # ARGF.readlines(sep=$/) -> array
# # ARGF.readlines(limit) -> array
# # ARGF.readlines(sep, limit) -> array
# #
# # ARGF.to_a(sep=$/) -> array
# # ARGF.to_a(limit) -> array
# # ARGF.to_a(sep, limit) -> array
# #
# # The remaining lines are documentation ...
#
# === Sections
#
# Sections allow you to group methods in a class into sensible containers. If
# you use the sections 'Public', 'Internal' and 'Deprecated' (the three
# allowed method statuses from TomDoc) the sections will be displayed in that
# order placing the most useful methods at the top. Otherwise, sections will
# be displayed in alphabetical order.
#
# [+:category:+ _section_]
# Adds this item to the named +section+ overriding the current section. Use
# this to group methods by section in RDoc output while maintaining a
# sensible ordering (like alphabetical).
#
# # :category: Utility Methods
# #
# # CGI escapes +text+
#
# def convert_string text
# CGI.escapeHTML text
# end
#
# An empty category will place the item in the default category:
#
# # :category:
# #
# # This method is in the default category
#
# def some_method
# # ...
# end
#
# Unlike the :section: directive, :category: is not sticky. The category
# only applies to the item immediately following the comment.
#
# Use the :section: directive to provide introductory text for a section of
# documentation.
#
# [+:section:+ _title_]
# Provides section introductory text in RDoc output. The title following
# +:section:+ is used as the section name and the remainder of the comment
# containing the section is used as introductory text. A section's comment
# block must be separated from following comment blocks. Use an empty title
# to switch to the default section.
#
# The :section: directive is sticky, so subsequent methods, aliases,
# attributes, and classes will be contained in this section until the
# section is changed. The :category: directive will override the :section:
# directive.
#
# A :section: comment block may have one or more lines before the :section:
# directive. These will be removed, and any identical lines at the end of
# the block are also removed. This allows you to add visual cues to the
# section.
#
# Example:
#
# # ----------------------------------------
# # :section: My Section
# # This is the section that I wrote.
# # See it glisten in the noon-day sun.
# # ----------------------------------------
#
# ##
# # Comment for some_method
#
# def some_method
# # ...
# end
#
# === Other directives
#
# [+:markup:+ _type_]
# Overrides the default markup type for this comment with the specified
# markup type. For Ruby files, if the first comment contains this directive
# it is applied automatically to all comments in the file.
#
# Unless you are converting between markup formats you should use a
# <code>.rdoc_options</code> file to specify the default documentation
# format for your entire project. See RDoc::Options@Saved+Options for
# instructions.
#
# At the top of a file the +:markup:+ directive applies to the entire file:
#
# # coding: UTF-8
# # :markup: TomDoc
#
# # TomDoc comment here ...
#
# class MyClass
# # ...
#
# For just one comment:
#
# # ...
# end
#
# # :markup: RDoc
# #
# # This is a comment in RDoc markup format ...
#
# def some_method
# # ...
#
# See Markup@CONTRIBUTING for instructions on adding a new markup format.
#
# [+:include:+ _filename_]
# Include the contents of the named file at this point. This directive
# must appear alone on one line, possibly preceded by spaces. In this
# position, it can be escaped with a \ in front of the first colon.
#
# The file will be searched for in the directories listed by the +--include+
# option, or in the current directory by default. The contents of the file
# will be shifted to have the same indentation as the ':' at the start of
# the +:include:+ directive.
#
# [+:title:+ _text_]
# Sets the title for the document. Equivalent to the <tt>--title</tt>
# command line parameter. (The command line parameter overrides any :title:
# directive in the source).
#
# [+:main:+ _name_]
# Equivalent to the <tt>--main</tt> command line parameter.

# RubyGems is the Ruby standard for publishing and managing third party
# libraries.
#
# For user documentation, see:
#
# * <tt>gem help</tt> and <tt>gem help [command]</tt>
# * {RubyGems User Guide}[https://guides.rubygems.org/]
# * {Frequently Asked Questions}[https://guides.rubygems.org/faqs]
#
# For gem developer documentation see:
#
# * {Creating Gems}[https://guides.rubygems.org/make-your-own-gem]

# * {RubyGems API}[https://www.rubydoc.info/github/rubygems/rubygems] (also available from
# <tt>gem server</tt>)
#
# == RubyGems Plugins
#
# RubyGems will load plugins in the latest version of each installed gem or
# $LOAD_PATH. Plugins must be named 'rubygems_plugin' (.rb, .so, etc) and
# placed at the root of your gem's #require_path. Plugins are installed at a
# special location and loaded on boot.
#
# For an example plugin, see the {Graph gem}[https://github.com/seattlerb/graph]
# which adds a `gem graph` command.
#
# == RubyGems Defaults, Packaging
#
# RubyGems defaults are stored in lib/rubygems/defaults.rb. If you're packaging
# RubyGems or implementing Ruby you can change RubyGems' defaults.
#
# For RubyGems packagers, provide lib/rubygems/defaults/operating_system.rb
# and override any defaults from lib/rubygems/defaults.rb.
#
# For Ruby implementers, provide lib/rubygems/defaults/#{RUBY_ENGINE}.rb and
# override any defaults from lib/rubygems/defaults.rb.
#
# If you need RubyGems to perform extra work on install or uninstall, your
# defaults override file can set pre/post install and uninstall hooks.
# See Gem::pre_install, Gem::pre_uninstall, Gem::post_install,
# Gem::post_uninstall.
#
# == Bugs
#
# You can submit bugs to the
# {RubyGems bug tracker}[https://github.com/rubygems/rubygems/issues]
# on GitHub

# A semi-compatible DSL for the Bundler Gemfile and Isolate gem dependencies
# files.
#
# To work with both the Bundler Gemfile and Isolate formats this
# implementation takes some liberties to allow compatibility with each, most
# notably in #source.
#
# A basic gem dependencies file will look like the following:
#
# source 'https://rubygems.org'
#
# gem 'rails', '3.2.14a
# gem 'devise', '~> 2.1', '>= 2.1.3'
# gem 'cancan'
# gem 'airbrake'
# gem 'pg'
#
# RubyGems recommends saving this as gem.deps.rb over Gemfile or Isolate.
#
# To install the gems in this Gemfile use `gem install -g` to install it and
# create a lockfile. The lockfile will ensure that when you make changes to
# your gem dependencies file a minimum amount of change is made to the
# dependencies of your gems.
#
# RubyGems can activate all the gems in your dependencies file at startup
# using the RUBYGEMS_GEMDEPS environment variable or through Gem.use_gemdeps.
# See Gem.use_gemdeps for details and warnings.
#
# See `gem help install` and `gem help gem_dependencies` for further details.

EOF
GEM_DEPENDENCIES = <<-EOF.freeze
A gem dependencies file allows installation of a consistent set of gems across
multiple environments. The RubyGems implementation is designed to be
compatible with Bundler's Gemfile format. You can see additional
documentation on the format at:
http://bundler.io
RubyGems automatically looks for these gem dependencies files:
* gem.deps.rb
* Gemfile
* Isolate
These files are looked up automatically using `gem install -g`, or you can
specify a custom file.
When the RUBYGEMS_GEMDEPS environment variable is set to a gem dependencies
file the gems from that file will be activated at startup time. Set it to a
specific filename or to "-" to have RubyGems automatically discover the gem
dependencies file by walking up from the current directory.
You can also activate gem dependencies at program startup using
Gem.use_gemdeps.
NOTE: Enabling automatic discovery on multiuser systems can lead to execution
of arbitrary code when used from directories outside your control.
Gem Dependencies
================
Use #gem to declare which gems you directly depend upon:
gem 'rake'
To depend on a specific set of versions:
gem 'rake', '~> 10.3', '>= 10.3.2'
RubyGems will require the gem name when activating the gem using
the RUBYGEMS_GEMDEPS environment variable or Gem::use_gemdeps. Use the
require: option to override this behavior if the gem does not have a file of
that name or you don't want to require those files:
gem 'my_gem', require: 'other_file'
To prevent RubyGems from requiring any files use:
gem 'my_gem', require: false
To load dependencies from a .gemspec file:
gemspec
RubyGems looks for the first .gemspec file in the current directory. To
override this use the name: option:
gemspec name: 'specific_gem'
To look in a different directory use the path: option:
gemspec name: 'specific_gem', path: 'gemspecs'
To depend on a gem unpacked into a local directory:
gem 'modified_gem', path: 'vendor/modified_gem'
To depend on a gem from git:
gem 'private_gem', git: 'git@my.company.example:private_gem.git'
To depend on a gem from github:
gem 'private_gem', github: 'my_company/private_gem'
To depend on a gem from a github gist:
gem 'bang', gist: '1232884'
Git, github and gist support the ref:, branch: and tag: options to specify a
commit reference or hash, branch or tag respectively to use for the gem.
Setting the submodules: option to true for git, github and gist dependencies
causes fetching of submodules when fetching the repository.
You can depend on multiple gems from a single repository with the git method:
git 'https://github.com/rails/rails.git' do
gem 'activesupport'
gem 'activerecord'
end
Gem Sources
===========
RubyGems uses the default sources for regular `gem install` for gem
dependencies files. Unlike bundler, you do need to specify a source.
You can override the sources used for downloading gems with:
source 'https://gem_server.example'
You may specify multiple sources. Unlike bundler the prepend: option is not
supported. Sources are used in-order, to prepend a source place it at the
front of the list.
Gem Platform
============
You can restrict gem dependencies to specific platforms with the #platform
and #platforms methods:
platform :ruby_21 do
gem 'debugger'
end
See the bundler Gemfile manual page for a list of platforms supported in a gem
dependencies file.:
http://bundler.io/v1.6/man/gemfile.5.html
Ruby Version and Engine Dependency
==================================
You can specify the version, engine and engine version of ruby to use with
your gem dependencies file. If you are not running the specified version
RubyGems will raise an exception.
To depend on a specific version of ruby:
ruby '2.1.2'
To depend on a specific ruby engine:
ruby '1.9.3', engine: 'jruby'
To depend on a specific ruby engine version:
ruby '1.9.3', engine: 'jruby', engine_version: '1.7.11'
Grouping Dependencies
=====================
Gem dependencies may be placed in groups that can be excluded from install.
Dependencies required for development or testing of your code may be excluded
when installed in a production environment.
A #gem dependency may be placed in a group using the group: option:
gem 'minitest', group: :test
To install dependencies from a gemfile without specific groups use the
`--without` option for `gem install -g`:
$ gem install -g --without test
The group: option also accepts multiple groups if the gem fits in multiple
categories.
Multiple groups may be excluded during install by comma-separating the groups for `--without` or by specifying `--without` multiple times.
The #group method can also be used to place gems in groups:
group :test do
gem 'minitest'
gem 'minitest-emoji'
end
The #group method allows multiple groups.
The #gemspec development dependencies are placed in the :development group by
default. This may be overridden with the :development_group option:
gemspec development_group: :other
EOF
PLATFORMS = <<-'EOF'.freeze
RubyGems platforms are composed of three parts, a CPU, an OS, and a
version. These values are taken from values in rbconfig.rb. You can view
your current platform by running `gem environment`.
RubyGems matches platforms as follows:
* The CPU must match exactly unless one of the platforms has
"universal" as the CPU or the local CPU starts with "arm" and the gem's
CPU is exactly "arm" (for gems that support generic ARM architecture).
* The OS must match exactly.
* The versions must match exactly unless one of the versions is nil.
For commands that install, uninstall and list gems, you can override what
RubyGems thinks your platform is with the --platform option. The platform
you pass must match "#{cpu}-#{os}" or "#{cpu}-#{os}-#{version}". On mswin
platforms, the version is the compiler version, not the OS version. (Ruby
compiled with VC6 uses "60" as the compiler version, VC8 uses "80".)
For the ARM architecture, gems with a platform of "arm-linux" should run on a
reasonable set of ARM CPUs and not depend on instructions present on a limited
subset of the architecture. For example, the binary should run on platforms
armv5, armv6hf, armv6l, armv7, etc. If you use the "arm-linux" platform
please test your gem on a variety of ARM hardware before release to ensure it
functions correctly.
Example platforms:
x86-freebsd # Any FreeBSD version on an x86 CPU
universal-darwin-8 # Darwin 8 only gems that run on any CPU
x86-mswin32-80 # Windows gems compiled with VC8
armv7-linux # Gem complied for an ARMv7 CPU running linux
arm-linux # Gem compiled for any ARM CPU running linux
When building platform gems, set the platform in the gem specification to
Gem::Platform::CURRENT. This will correctly mark the gem with your ruby's
platform.

The install command installs local or remote gem into a gem repository.
For gems with executables ruby installs a wrapper file into the executable
directory by default. This can be overridden with the --no-wrappers option.
The wrapper allows you to choose among alternate gem versions using _version_.
For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer
version is also installed.
Gem Dependency Files
====================
RubyGems can install a consistent set of gems across multiple environments
using `gem install -g` when a gem dependencies file (gem.deps.rb, Gemfile or
Isolate) is present. If no explicit file is given RubyGems attempts to find
one in the current directory.
When the RUBYGEMS_GEMDEPS environment variable is set to a gem dependencies
file the gems from that file will be activated at startup time. Set it to a
specific filename or to "-" to have RubyGems automatically discover the gem
dependencies file by walking up from the current directory.
NOTE: Enabling automatic discovery on multiuser systems can lead to
execution of arbitrary code when used from directories outside your control.
Extension Install Failures
==========================
If an extension fails to compile during gem installation the gem
specification is not written out, but the gem remains unpacked in the
repository. You may need to specify the path to the library's headers and
libraries to continue. You can do this by adding a -- between RubyGems'
options and the extension's build options:
$ gem install some_extension_gem
[build fails]
Gem files will remain installed in \\
/path/to/gems/some_extension_gem-1.0 for inspection.
Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out
$ gem install some_extension_gem -- --with-extension-lib=/path/to/lib
[build succeeds]
$ gem list some_extension_gem
*** LOCAL GEMS ***
some_extension_gem (1.0)
$
If you correct the compilation errors by editing the gem files you will need
to write the specification by hand. For example:
$ gem install some_extension_gem
[build fails]
Gem files will remain installed in \\
/path/to/gems/some_extension_gem-1.0 for inspection.
Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out
$ [cd /path/to/gems/some_extension_gem-1.0]
$ [edit files or what-have-you and run make]
$ gem spec ../../cache/some_extension_gem-1.0.gem --ruby > \\

The cert command manages signing keys and certificates for creating signed
gems. Your signing certificate and private key are typically stored in
~/.gem/gem-public_cert.pem and ~/.gem/gem-private_key.pem respectively.
To build a certificate for signing gems:
gem cert --build you@example
If you already have an RSA key, or are creating a new certificate for an
existing key:
gem cert --build you@example --private-key /path/to/key.pem
If you wish to trust a certificate you can add it to the trust list with:
gem cert --add /path/to/cert.pem
You can list trusted certificates with:
gem cert --list
or:
gem cert --list cert_subject_substring
If you wish to remove a previously trusted certificate:
gem cert --remove cert_subject_substring
To sign another gem author's certificate:
gem cert --sign /path/to/other_cert.pem
For further reading on signing gems see `ri Gem::Security`.

RubyGems fetches gems from the sources you have configured (stored in your
~/.gemrc).
The default source is https://rubygems.org, but you may have other sources
configured. This guide will help you update your sources or configure
yourself to use your own gem server.
Without any arguments the sources lists your currently configured sources:
$ gem sources
*** CURRENT SOURCES ***
https://rubygems.org
This may list multiple sources or non-rubygems sources. You probably
configured them before or have an old `~/.gemrc`. If you have sources you
do not recognize you should remove them.
RubyGems has been configured to serve gems via the following URLs through
its history:
* http://gems.rubyforge.org (RubyGems 1.3.6 and earlier)
* https://rubygems.org/ (RubyGems 1.3.7 through 1.8.25)
* https://rubygems.org (RubyGems 2.0.1 and newer)
Since all of these sources point to the same set of gems you only need one
of them in your list. https://rubygems.org is recommended as it brings the
protections of an SSL connection to gem downloads.
To add a source use the --add argument:
$ gem sources --add https://rubygems.org
https://rubygems.org added to sources
RubyGems will check to see if gems can be installed from the source given
before it is added.
To remove a source use the --remove argument:
$ gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources

The lock command will generate a list of +gem+ statements that will lock down
the versions for the gem given in the command line. It will specify exact
versions in the requirements list to ensure that the gems loaded will always
be consistent. A full recursive search of all effected gems will be
generated.
Example:
gem lock rails-1.0.0 > lockdown.rb
will produce in lockdown.rb:
require "rubygems"
gem 'rails', '= 1.0.0'
gem 'rake', '= 0.7.0.1'
gem 'activesupport', '= 1.2.5'
gem 'activerecord', '= 1.13.2'
gem 'actionpack', '= 1.11.2'
gem 'actionmailer', '= 1.1.5'
gem 'actionwebservice', '= 1.0.0'
Just load lockdown.rb from your application to ensure that the current
versions are loaded. Make sure that lockdown.rb is loaded *before* any
other require statements.
Notice that rails 1.0.0 only requires that rake 0.6.2 or better be used.
Rake-0.7.0.1 is the most recent version installed that satisfies that, so we
lock it down to the exact version.

The environment command lets you query rubygems for its configuration for
use in shell scripts or as a debugging aid.
The RubyGems environment can be controlled through command line arguments,
gemrc files, environment variables and built-in defaults.
Command line argument defaults and some RubyGems defaults can be set in a
~/.gemrc file for individual users and a gemrc in the SYSTEM CONFIGURATION
DIRECTORY for all users. These files are YAML files with the following YAML
keys:
:sources: A YAML array of remote gem repositories to install gems from
:verbose: Verbosity of the gem command. false, true, and :really are the
levels
:update_sources: Enable/disable automatic updating of repository metadata
:backtrace: Print backtrace when RubyGems encounters an error
:gempath: The paths in which to look for gems
:disable_default_gem_server: Force specification of gem server host on push
<gem_command>: A string containing arguments for the specified gem command
Example:
:verbose: false
install: --no-wrappers
update: --no-wrappers
:disable_default_gem_server: true
RubyGems' default local repository can be overridden with the GEM_PATH and
GEM_HOME environment variables. GEM_HOME sets the default repository to
install into. GEM_PATH allows multiple local repositories to be searched for
gems.
If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
proxy server.
If you would like to push gems to a private gem server the RUBYGEMS_HOST
environment variable can be set to the URI for that server.
If you are packaging RubyGems all of RubyGems' defaults are in
lib/rubygems/defaults.rb. You may override these in
lib/rubygems/defaults/operating_system.rb

# = Signing gems
#
# The Gem::Security implements cryptographic signatures for gems. The section
# below is a step-by-step guide to using signed gems and generating your own.
#
# == Walkthrough
#
# === Building your certificate
#
# In order to start signing your gems, you'll need to build a private key and
# a self-signed certificate. Here's how:
#
# # build a private key and certificate for yourself:
# $ gem cert --build you@example.com
#
# This could take anywhere from a few seconds to a minute or two, depending on
# the speed of your computer (public key algorithms aren't exactly the
# speediest crypto algorithms in the world). When it's finished, you'll see
# the files "gem-private_key.pem" and "gem-public_cert.pem" in the current
# directory.
#
# First things first: Move both files to ~/.gem if you don't already have a
# key and certificate in that directory. Ensure the file permissions make the
# key unreadable by others (by default the file is saved securely).
#
# Keep your private key hidden; if it's compromised, someone can sign packages
# as you (note: PKI has ways of mitigating the risk of stolen keys; more on
# that later).
#
# === Signing Gems
#
# In RubyGems 2 and newer there is no extra work to sign a gem. RubyGems will
# automatically find your key and certificate in your home directory and use
# them to sign newly packaged gems.
#
# If your certificate is not self-signed (signed by a third party) RubyGems
# will attempt to load the certificate chain from the trusted certificates.
# Use <code>gem cert --add signing_cert.pem</code> to add your signers as
# trusted certificates. See below for further information on certificate
# chains.
#
# If you build your gem it will automatically be signed. If you peek inside
# your gem file, you'll see a couple of new files have been added:
#
# $ tar tf your-gem-1.0.gem
# metadata.gz
# metadata.gz.sig # metadata signature
# data.tar.gz
# data.tar.gz.sig # data signature
# checksums.yaml.gz
# checksums.yaml.gz.sig # checksums signature
#
# === Manually signing gems
#
# If you wish to store your key in a separate secure location you'll need to
# set your gems up for signing by hand. To do this, set the
# <code>signing_key</code> and <code>cert_chain</code> in the gemspec before
# packaging your gem:
#
# s.signing_key = '/secure/path/to/gem-private_key.pem'
# s.cert_chain = %w[/secure/path/to/gem-public_cert.pem]
#
# When you package your gem with these options set RubyGems will automatically
# load your key and certificate from the secure paths.
#
# === Signed gems and security policies
#
# Now let's verify the signature. Go ahead and install the gem, but add the
# following options: <code>-P HighSecurity</code>, like this:
#
# # install the gem with using the security policy "HighSecurity"
# $ sudo gem install your.gem -P HighSecurity
#
# The <code>-P</code> option sets your security policy -- we'll talk about
# that in just a minute. Eh, what's this?
#
# $ gem install -P HighSecurity your-gem-1.0.gem
# ERROR: While executing gem ... (Gem::Security::Exception)
# root cert /CN=you/DC=example is not trusted
#
# The culprit here is the security policy. RubyGems has several different
# security policies. Let's take a short break and go over the security
# policies. Here's a list of the available security policies, and a brief
# description of each one:
#
# * NoSecurity - Well, no security at all. Signed packages are treated like
# unsigned packages.
# * LowSecurity - Pretty much no security. If a package is signed then
# RubyGems will make sure the signature matches the signing
# certificate, and that the signing certificate hasn't expired, but
# that's it. A malicious user could easily circumvent this kind of
# security.
# * MediumSecurity - Better than LowSecurity and NoSecurity, but still
# fallible. Package contents are verified against the signing
# certificate, and the signing certificate is checked for validity,
# and checked against the rest of the certificate chain (if you don't
# know what a certificate chain is, stay tuned, we'll get to that).
# The biggest improvement over LowSecurity is that MediumSecurity
# won't install packages that are signed by untrusted sources.
# Unfortunately, MediumSecurity still isn't totally secure -- a
# malicious user can still unpack the gem, strip the signatures, and
# distribute the gem unsigned.
# * HighSecurity - Here's the bugger that got us into this mess.
# The HighSecurity policy is identical to the MediumSecurity policy,
# except that it does not allow unsigned gems. A malicious user
# doesn't have a whole lot of options here; they can't modify the
# package contents without invalidating the signature, and they can't
# modify or remove signature or the signing certificate chain, or
# RubyGems will simply refuse to install the package. Oh well, maybe
# they'll have better luck causing problems for CPAN users instead :).
#
# The reason RubyGems refused to install your shiny new signed gem was because
# it was from an untrusted source. Well, your code is infallible (naturally),
# so you need to add yourself as a trusted source:
#
# # add trusted certificate
# gem cert --add ~/.gem/gem-public_cert.pem
#
# You've now added your public certificate as a trusted source. Now you can
# install packages signed by your private key without any hassle. Let's try
# the install command above again:
#
# # install the gem with using the HighSecurity policy (and this time
# # without any shenanigans)
# $ gem install -P HighSecurity your-gem-1.0.gem
# Successfully installed your-gem-1.0
# 1 gem installed
#
# This time RubyGems will accept your signed package and begin installing.
#
# While you're waiting for RubyGems to work it's magic, have a look at some of
# the other security commands by running <code>gem help cert</code>:
#
# Options:
# -a, --add CERT Add a trusted certificate.
# -l, --list [FILTER] List trusted certificates where the
# subject contains FILTER
# -r, --remove FILTER Remove trusted certificates where the
# subject contains FILTER
# -b, --build EMAIL_ADDR Build private key and self-signed
# certificate for EMAIL_ADDR
# -C, --certificate CERT Signing certificate for --sign
# -K, --private-key KEY Key for --sign or --build
# -A, --key-algorithm ALGORITHM Select key algorithm for --build from RSA, DSA, or EC. Defaults to RSA.
# -s, --sign CERT Signs CERT with the key from -K
# and the certificate from -C
# -d, --days NUMBER_OF_DAYS Days before the certificate expires
# -R, --re-sign Re-signs the certificate from -C with the key from -K
#
# We've already covered the <code>--build</code> option, and the
# <code>--add</code>, <code>--list</code>, and <code>--remove</code> commands
# seem fairly straightforward; they allow you to add, list, and remove the
# certificates in your trusted certificate list. But what's with this
# <code>--sign</code> option?
#
# === Certificate chains
#
# To answer that question, let's take a look at "certificate chains", a
# concept I mentioned earlier. There are a couple of problems with
# self-signed certificates: first of all, self-signed certificates don't offer
# a whole lot of security. Sure, the certificate says Yukihiro Matsumoto, but
# how do I know it was actually generated and signed by matz himself unless he
# gave me the certificate in person?
#
# The second problem is scalability. Sure, if there are 50 gem authors, then
# I have 50 trusted certificates, no problem. What if there are 500 gem
# authors? 1000? Having to constantly add new trusted certificates is a
# pain, and it actually makes the trust system less secure by encouraging
# RubyGems users to blindly trust new certificates.
#
# Here's where certificate chains come in. A certificate chain establishes an
# arbitrarily long chain of trust between an issuing certificate and a child
# certificate. So instead of trusting certificates on a per-developer basis,
# we use the PKI concept of certificate chains to build a logical hierarchy of
# trust. Here's a hypothetical example of a trust hierarchy based (roughly)
# on geography:
#
# --------------------------
# | rubygems@rubygems.org |
# --------------------------
# |
# -----------------------------------
# | |
# ---------------------------- -----------------------------
# | seattlerb@seattlerb.org | | dcrubyists@richkilmer.com |
# ---------------------------- -----------------------------
# | | | |
# --------------- ---------------- ----------- --------------
# | drbrain | | zenspider | | pabs@dc | | tomcope@dc |
# --------------- ---------------- ----------- --------------
#
#
# Now, rather than having 4 trusted certificates (one for drbrain, zenspider,
# pabs@dc, and tomecope@dc), a user could actually get by with one
# certificate, the "rubygems@rubygems.org" certificate.
#
# Here's how it works:
#
# I install "rdoc-3.12.gem", a package signed by "drbrain". I've never heard
# of "drbrain", but his certificate has a valid signature from the
# "seattle.rb@seattlerb.org" certificate, which in turn has a valid signature
# from the "rubygems@rubygems.org" certificate. Voila! At this point, it's
# much more reasonable for me to trust a package signed by "drbrain", because
# I can establish a chain to "rubygems@rubygems.org", which I do trust.
#
# === Signing certificates
#
# The <code>--sign</code> option allows all this to happen. A developer
# creates their build certificate with the <code>--build</code> option, then
# has their certificate signed by taking it with them to their next regional
# Ruby meetup (in our hypothetical example), and it's signed there by the
# person holding the regional RubyGems signing certificate, which is signed at
# the next RubyConf by the holder of the top-level RubyGems certificate. At
# each point the issuer runs the same command:
#
# # sign a certificate with the specified key and certificate
# # (note that this modifies client_cert.pem!)
# $ gem cert -K /mnt/floppy/issuer-priv_key.pem -C issuer-pub_cert.pem
# --sign client_cert.pem
#
# Then the holder of issued certificate (in this case, your buddy "drbrain"),
# can start using this signed certificate to sign RubyGems. By the way, in
# order to let everyone else know about his new fancy signed certificate,
# "drbrain" would save his newly signed certificate as
# <code>~/.gem/gem-public_cert.pem</code>
#
# Obviously this RubyGems trust infrastructure doesn't exist yet. Also, in
# the "real world", issuers actually generate the child certificate from a
# certificate request, rather than sign an existing certificate. And our
# hypothetical infrastructure is missing a certificate revocation system.
# These are that can be fixed in the future...
#
# At this point you should know how to do all of these new and interesting
# things:
#
# * build a gem signing key and certificate
# * adjust your security policy
# * modify your trusted certificate list
# * sign a certificate
#
# == Manually verifying signatures
#
# In case you don't trust RubyGems you can verify gem signatures manually:
#
# 1. Fetch and unpack the gem
#
# gem fetch some_signed_gem
# tar -xf some_signed_gem-1.0.gem
#
# 2. Grab the public key from the gemspec
#
# gem spec some_signed_gem-1.0.gem cert_chain | \
# ruby -ryaml -e 'puts YAML.load($stdin)' > public_key.crt
#
# 3. Generate a SHA1 hash of the data.tar.gz
#
# openssl dgst -sha1 < data.tar.gz > my.hash
#
# 4. Verify the signature
#
# openssl rsautl -verify -inkey public_key.crt -certin \
# -in data.tar.gz.sig > verified.hash
#
# 5. Compare your hash to the verified hash
#
# diff -s verified.hash my.hash
#
# 6. Repeat 5 and 6 with metadata.gz
#
# == OpenSSL Reference
#
# The .pem files generated by --build and --sign are PEM files. Here's a
# couple of useful OpenSSL commands for manipulating them:
#
# # convert a PEM format X509 certificate into DER format:
# # (note: Windows .cer files are X509 certificates in DER format)
# $ openssl x509 -in input.pem -outform der -out output.der
#
# # print out the certificate in a human-readable format:
# $ openssl x509 -in input.pem -noout -text
#
# And you can do the same thing with the private key file as well:
#
# # convert a PEM format RSA key into DER format:
# $ openssl rsa -in input_key.pem -outform der -out output_key.der
#
# # print out the key in a human readable format:
# $ openssl rsa -in input_key.pem -noout -text
#
# == Bugs/TODO
#
# * There's no way to define a system-wide trust list.
# * custom security policies (from a YAML file, etc)
# * Simple method to generate a signed certificate request
# * Support for OCSP, SCVP, CRLs, or some other form of cert status check
# (list is in order of preference)
# * Support for encrypted private keys
# * Some sort of semi-formal trust hierarchy (see long-winded explanation
# above)
# * Path discovery (for gem certificate chains that don't have a self-signed
# root) -- by the way, since we don't have this, THE ROOT OF THE CERTIFICATE
# CHAIN MUST BE SELF SIGNED if Policy#verify_root is true (and it is for the
# MediumSecurity and HighSecurity policies)
# * Better explanation of X509 naming (ie, we don't have to use email
# addresses)
# * Honor AIA field (see note about OCSP above)
# * Honor extension restrictions
# * Might be better to store the certificate chain as a PKCS#7 or PKCS#12
# file, instead of an array embedded in the metadata.

##
# The Version class processes string versions into comparable
# values. A version string should normally be a series of numbers
# separated by periods. Each part (digits separated by periods) is
# considered its own number, and these are used for sorting. So for
# instance, 3.10 sorts higher than 3.2 because ten is greater than
# two.
#
# If any part contains letters (currently only a-z are supported) then
# that version is considered prerelease. Versions with a prerelease
# part in the Nth part sort less than versions with N-1
# parts. Prerelease parts are sorted alphabetically using the normal
# Ruby string sorting rules. If a prerelease part contains both
# letters and numbers, it will be broken into multiple parts to
# provide expected sort behavior (1.0.a10 becomes 1.0.a.10, and is
# greater than 1.0.a9).
#
# Prereleases sort between real releases (newest to oldest):
#
# 1. 1.0
# 2. 1.0.b1
# 3. 1.0.a.2
# 4. 0.9
#
# If you want to specify a version restriction that includes both prereleases
# and regular releases of the 1.x series this is the best way:
#
# s.add_dependency 'example', '>= 1.0.0.a', '< 2.0.0'
#
# == How Software Changes
#
# Users expect to be able to specify a version constraint that gives them
# some reasonable expectation that new versions of a library will work with
# their software if the version constraint is true, and not work with their
# software if the version constraint is false. In other words, the perfect
# system will accept all compatible versions of the library and reject all
# incompatible versions.
#
# Libraries change in 3 ways (well, more than 3, but stay focused here!).
#
# 1. The change may be an implementation detail only and have no effect on
# the client software.
# 2. The change may add new features, but do so in a way that client software
# written to an earlier version is still compatible.
# 3. The change may change the public interface of the library in such a way
# that old software is no longer compatible.
#
# Some examples are appropriate at this point. Suppose I have a Stack class
# that supports a <tt>push</tt> and a <tt>pop</tt> method.
#
# === Examples of Category 1 changes:
#
# * Switch from an array based implementation to a linked-list based
# implementation.
# * Provide an automatic (and transparent) backing store for large stacks.
#
# === Examples of Category 2 changes might be:
#
# * Add a <tt>depth</tt> method to return the current depth of the stack.
# * Add a <tt>top</tt> method that returns the current top of stack (without
# changing the stack).
# * Change <tt>push</tt> so that it returns the item pushed (previously it
# had no usable return value).
#
# === Examples of Category 3 changes might be:
#
# * Changes <tt>pop</tt> so that it no longer returns a value (you must use
# <tt>top</tt> to get the top of the stack).
# * Rename the methods to <tt>push_item</tt> and <tt>pop_item</tt>.
#
# == RubyGems Rational Versioning
#
# * Versions shall be represented by three non-negative integers, separated
# by periods (e.g. 3.1.4). The first integers is the "major" version
# number, the second integer is the "minor" version number, and the third
# integer is the "build" number.
#
# * A category 1 change (implementation detail) will increment the build
# number.
#
# * A category 2 change (backwards compatible) will increment the minor
# version number and reset the build number.
#
# * A category 3 change (incompatible) will increment the major build number
# and reset the minor and build numbers.
#
# * Any "public" release of a gem should have a different version. Normally
# that means incrementing the build number. This means a developer can
# generate builds all day long, but as soon as they make a public release,
# the version must be updated.
#
# === Examples
#
# Let's work through a project lifecycle using our Stack example from above.
#
# Version 0.0.1:: The initial Stack class is release.
# Version 0.0.2:: Switched to a linked=list implementation because it is
# cooler.
# Version 0.1.0:: Added a <tt>depth</tt> method.
# Version 1.0.0:: Added <tt>top</tt> and made <tt>pop</tt> return nil
# (<tt>pop</tt> used to return the old top item).
# Version 1.1.0:: <tt>push</tt> now returns the value pushed (it used it
# return nil).
# Version 1.1.1:: Fixed a bug in the linked list implementation.
# Version 1.1.2:: Fixed a bug introduced in the last fix.
#
# Client A needs a stack with basic push/pop capability. They write to the
# original interface (no <tt>top</tt>), so their version constraint looks like:
#
# gem 'stack', '>= 0.0'
#
# Essentially, any version is OK with Client A. An incompatible change to
# the library will cause them grief, but they are willing to take the chance
# (we call Client A optimistic).
#
# Client B is just like Client A except for two things: (1) They use the
# <tt>depth</tt> method and (2) they are worried about future
# incompatibilities, so they write their version constraint like this:
#
# gem 'stack', '~> 0.1'
#
# The <tt>depth</tt> method was introduced in version 0.1.0, so that version
# or anything later is fine, as long as the version stays below version 1.0
# where incompatibilities are introduced. We call Client B pessimistic
# because they are worried about incompatible future changes (it is OK to be
# pessimistic!).
#
# == Preventing Version Catastrophe:
#
# From: http://blog.zenspider.com/2008/10/rubygems-howto-preventing-cata.html
#
# Let's say you're depending on the fnord gem version 2.y.z. If you
# specify your dependency as ">= 2.0.0" then, you're good, right? What
# happens if fnord 3.0 comes out and it isn't backwards compatible
# with 2.y.z? Your stuff will break as a result of using ">=". The
# better route is to specify your dependency with an "approximate" version
# specifier ("~>"). They're a tad confusing, so here is how the dependency
# specifiers work:
#
# Specification From ... To (exclusive)
# ">= 3.0" 3.0 ... ∞
# "~> 3.0" 3.0 ... 4.0
# "~> 3.0.0" 3.0.0 ... 3.1
# "~> 3.5" 3.5 ... 4.0
# "~> 3.5.0" 3.5.0 ... 3.6
# "~> 3" 3.0 ... 4.0
#
# For the last example, single-digit versions are automatically extended with
# a zero to give a sensible result.

#
# === Introduction
#
# Gem::OptionParser is a class for command-line option analysis. It is much more
# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
# solution.
#
# === Features
#
# 1. The argument specification and the code to handle it are written in the
# same place.
# 2. It can output an option summary; you don't need to maintain this string
# separately.
# 3. Optional and mandatory arguments are specified very gracefully.
# 4. Arguments can be automatically converted to a specified class.
# 5. Arguments can be restricted to a certain set.
#
# All of these features are demonstrated in the examples below. See
# #make_switch for full documentation.
#
# === Minimal example
#
# require 'rubygems/optparse/lib/optparse'
#
# options = {}
# Gem::OptionParser.new do |parser|
# parser.banner = "Usage: example.rb [options]"
#
# parser.on("-v", "--[no-]verbose", "Run verbosely") do |v|
# options[:verbose] = v
# end
# end.parse!
#
# p options
# p ARGV
#
# === Generating Help
#
# Gem::OptionParser can be used to automatically generate help for the commands you
# write:
#
# require 'rubygems/optparse/lib/optparse'
#
# Options = Struct.new(:name)
#
# class Parser
# def self.parse(options)
# args = Options.new("world")
#
# opt_parser = Gem::OptionParser.new do |parser|
# parser.banner = "Usage: example.rb [options]"
#
# parser.on("-nNAME", "--name=NAME", "Name to say hello to") do |n|
# args.name = n
# end
#
# parser.on("-h", "--help", "Prints this help") do
# puts parser
# exit
# end
# end
#
# opt_parser.parse!(options)
# return args
# end
# end
# options = Parser.parse %w[--help]
#
# #=>
# # Usage: example.rb [options]
# # -n, --name=NAME Name to say hello to
# # -h, --help Prints this help
#
# === Required Arguments
#
# For options that require an argument, option specification strings may include an
# option name in all caps. If an option is used without the required argument,
# an exception will be raised.
#
# require 'rubygems/optparse/lib/optparse'
#
# options = {}
# Gem::OptionParser.new do |parser|
# parser.on("-r", "--require LIBRARY",
# "Require the LIBRARY before executing your script") do |lib|
# puts "You required #{lib}!"
# end
# end.parse!
#
# Used:
#
# $ ruby optparse-test.rb -r
# optparse-test.rb:9:in `<main>': missing argument: -r (Gem::OptionParser::MissingArgument)
# $ ruby optparse-test.rb -r my-library
# You required my-library!
#
# === Type Coercion
#
# Gem::OptionParser supports the ability to coerce command line arguments
# into objects for us.
#
# Gem::OptionParser comes with a few ready-to-use kinds of type
# coercion. They are:
#
# - Date -- Anything accepted by +Date.parse+
# - DateTime -- Anything accepted by +DateTime.parse+
# - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+
# - URI -- Anything accepted by +URI.parse+
# - Shellwords -- Anything accepted by +Shellwords.shellwords+
# - String -- Any non-empty string
# - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040)
# - Float -- Any float. (e.g. 10, 3.14, -100E+13)
# - Numeric -- Any integer, float, or rational (1, 3.4, 1/3)
# - DecimalInteger -- Like +Integer+, but no octal format.
# - OctalInteger -- Like +Integer+, but no decimal format.
# - DecimalNumeric -- Decimal integer or float.
# - TrueClass -- Accepts '+, yes, true, -, no, false' and
# defaults as +true+
# - FalseClass -- Same as +TrueClass+, but defaults to +false+
# - Array -- Strings separated by ',' (e.g. 1,2,3)
# - Regexp -- Regular expressions. Also includes options.
#
# We can also add our own coercions, which we will cover below.
#
# ==== Using Built-in Conversions
#
# As an example, the built-in +Time+ conversion is used. The other built-in
# conversions behave in the same way.
# Gem::OptionParser will attempt to parse the argument
# as a +Time+. If it succeeds, that time will be passed to the
# handler block. Otherwise, an exception will be raised.
#
# require 'rubygems/optparse/lib/optparse'
# require 'rubygems/optparse/lib/optparse/time'
# Gem::OptionParser.new do |parser|
# parser.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
# p time
# end
# end.parse!
#
# Used:
#
# $ ruby optparse-test.rb -t nonsense
# ... invalid argument: -t nonsense (Gem::OptionParser::InvalidArgument)
# $ ruby optparse-test.rb -t 10-11-12
# 2010-11-12 00:00:00 -0500
# $ ruby optparse-test.rb -t 9:30
# 2014-08-13 09:30:00 -0400
#
# ==== Creating Custom Conversions
#
# The +accept+ method on Gem::OptionParser may be used to create converters.
# It specifies which conversion block to call whenever a class is specified.
# The example below uses it to fetch a +User+ object before the +on+ handler receives it.
#
# require 'rubygems/optparse/lib/optparse'
#
# User = Struct.new(:id, :name)
#
# def find_user id
# not_found = ->{ raise "No User Found for id #{id}" }
# [ User.new(1, "Sam"),
# User.new(2, "Gandalf") ].find(not_found) do |u|
# u.id == id
# end
# end
#
# op = Gem::OptionParser.new
# op.accept(User) do |user_id|
# find_user user_id.to_i
# end
#
# op.on("--user ID", User) do |user|
# puts user
# end
#
# op.parse!
#
# Used:
#
# $ ruby optparse-test.rb --user 1
# #<struct User id=1, name="Sam">
# $ ruby optparse-test.rb --user 2
# #<struct User id=2, name="Gandalf">
# $ ruby optparse-test.rb --user 3
# optparse-test.rb:15:in `block in find_user': No User Found for id 3 (RuntimeError)
#
# === Store options to a Hash
#
# The +into+ option of +order+, +parse+ and so on methods stores command line options into a Hash.
#
# require 'rubygems/optparse/lib/optparse'

# Can be used for quick navigation to the rdoc documentation. You can then
# define a search shortcut for your browser. E.g. in Firefox connect
# 'shortcut:rdoc' to http://localhost:8808/rdoc?q=%s template. Then you can
# directly open the ActionPack documentation by typing 'rdoc actionp'. If
# there are multiple hits for the search term, they are presented as a list
# with links.
#
# Search algorithm aims for an intuitive search:
# 1. first try to find the gems and documentation folders which name
# starts with the search term
# 2. search for entries, that *contain* the search term
# 3. show all the gems
#
# If there is only one search hit, user is immediately redirected to the
# documentation for the particular gem, otherwise a list with results is
# shown.
#
# === Additional trick - install documentation for Ruby core
#
# Note: please adjust paths accordingly use for example 'locate yaml.rb' and
# 'gem environment' to identify directories, that are specific for your
# local installation
#
# 1. install Ruby sources
# cd /usr/src
# sudo apt-get source ruby
#
# 2. generate documentation
# rdoc -o /usr/lib/ruby/gems/1.8/doc/core/rdoc \
# /usr/lib/ruby/1.8 ruby1.8-1.8.7.72

# By typing 'rdoc core' you can now access the core documentation
