Installs a gem along with all its dependencies from local and remote gems.
Gem::DependencyList is used for installing and uninstalling gems in the correct order to avoid conflicts.
Raised by Gem::Validator when something is not right in a gem.
Raised to indicate that a system exit should occur with the specified exit_code
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.
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"]
The SourceList represents the sources rubygems has been configured to use. A source may be created from an array of sources:
Gem::SourceList.from %w[https://rubygems.example https://internal.example]
Or by adding them:
sources = Gem::SourceList.new sources << 'https://rubygems.example'
The most common way to get a SourceList is Gem.sources.
Gem::StubSpecification reads the stub: line from the gemspec. This prevents us having to eval the entire gemspec in order to find out certain information.
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.
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'
Not a URI.
URI is valid, bad usage is not.
An HTTP request. This is consumed by service and do_* methods in WEBrick servlets
Base TCP server class. You must subclass GenericServer and provide a run method.
