Raised when removing a gem with the uninstall command fails
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:
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.
S3URISigner implements AWS SigV4 for S3 Source to avoid a dependency on the aws-sdk-* gems More on AWS SigV4: docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html
SpecFetcher handles metadata updates from remote gem repositories.
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.
Raised by Timeout.timeout when the block times out.
Base class for all URI exceptions.
Not a URI.
URI is valid, bad usage is not.
