Signals that a remote operation cannot be conducted, probably due to not being connected (or just not finding host).

Run an instance of the gem program.

Gem::GemRunner is only intended for internal use by RubyGems itself. It does not form any public API and may change at any time for any reason.

If you would like to duplicate functionality of ‘gem` commands, use the classes they call directly.

Top level class for building the gem repository index.

The installer installs the files contained in the .gem into the Gem.home.

Gem::Installer does the work of putting files in all the right places on the filesystem including unpacking the gem into its gem dir, installing the gemspec in the specifications dir, storing the cached gem in the cache dir, and installing either wrappers or symlinks for executables.

The installer invokes pre and post install hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_install and Gem.post_install for details.

Create a package based upon a Gem::Specification. Gem packages, as well as zip files and tar/gzipped packages can be produced by this task.

In addition to the Rake targets generated by Rake::PackageTask, a Gem::PackageTask will also generate the following tasks:

“package_dir/name-version.gem”

Create a RubyGems package with the given name and version.

Example using a Gem::Specification:

require 'rubygems'
require 'rubygems/package_task'

spec = Gem::Specification.new do |s|
  s.summary = "Ruby based make-like utility."
  s.name = 'rake'
  s.version = PKG_VERSION
  s.requirements << 'none'
  s.files = PKG_FILES
  s.description = <<-EOF
Rake is a Make-like program implemented in Ruby. Tasks
and dependencies are specified in standard Ruby syntax.
  EOF
end

Gem::PackageTask.new(spec) do |pkg|
  pkg.need_zip = true
  pkg.need_tar = true
end

Gem::PathSupport facilitates the GEM_HOME and GEM_PATH environment settings to the rest of RubyGems.

RemoteFetcher handles the details of fetching gems and gem information from a remote source.

A RequestSet groups a request to activate a set of dependencies.

nokogiri = Gem::Dependency.new 'nokogiri', '~> 1.6'
pg = Gem::Dependency.new 'pg', '~> 0.14'

set = Gem::RequestSet.new nokogiri, pg

requests = set.resolve

p requests.map { |r| r.full_name }
#=> ["nokogiri-1.6.0", "mini_portile-0.5.1", "pg-0.17.0"]

Given a set of Gem::Dependency objects as needed and a way to query the set of available specs via set, calculates a set of ActivationRequest objects which indicate all the specs that should be activated to meet the all the requirements.

SpecFetcher handles metadata updates from remote gem repositories.

RubyGemTestCase provides a variety of methods for testing rubygems and gem-related behavior in a sandbox. Through RubyGemTestCase you can install and uninstall gems, fetch remote gems through a stub fetcher and be assured your normal set of gems is not affected.

Tests are always run at a safe level of 1.

A fake Gem::RemoteFetcher for use in tests or to avoid real live HTTP requests when testing code that uses RubyGems.

Example:

@fetcher = Gem::FakeFetcher.new
@fetcher.data['http://gems.example.com/yaml'] = source_index.to_yaml
Gem::RemoteFetcher.fetcher = @fetcher

# invoke RubyGems code

paths = @fetcher.paths
assert_equal 'http://gems.example.com/yaml', paths.shift
assert paths.empty?, paths.join(', ')

See RubyGems’ tests for more examples of FakeFetcher.

An Uninstaller.

The uninstaller fires pre and post uninstall hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_uninstall and Gem.post_uninstall for details.

The UriFormatter handles URIs from user-input and escaping.

uf = Gem::UriFormatter.new 'example.com'

p uf.normalize #=> 'http://example.com'

Subclass of StreamUI that instantiates the user interaction using STDIN, STDOUT, and STDERR.

Any result of command execution is a Filter.

This class includes Enumerable, therefore a Filter object can use all Enumerable facilities.
