The InvalidRSSError
error is the base class for a variety of errors related to a poorly-formed RSS
feed. Rescue this error if you only care that a file could be invalid, but don’t care how it is invalid.
Gem::DependencyList
is used for installing and uninstalling gems in the correct order to avoid conflicts.
Raised when attempting to uninstall a gem that isn’t in GEM_HOME.
Potentially raised when a specification is validated.
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
Top level class for building the gem repository index.
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.
The UriFormatter
handles URIs from user-input and escaping.
uf = Gem::UriFormatter.new 'example.com' p uf.normalize #=> 'http://example.com'
Not a URI
component.
URI
is valid, bad usage is not.
