Map from option/keyword string to object with completion.
Raises when ambiguously completable string is encountered.
Raises when switch is undefined.
A set of rule and position in it’s RHS. Note that the number of pointers is more than rule’s RHS array, because pointer points right edge of the final symbol when reducing.
BasicSpecification
is an abstract class which implements some common code used by both Specification and StubSpecification.
Base exception class for RubyGems. All exception raised by RubyGems are a subclass of this one.
Raised by Gem::Resolver
when a Gem::Dependency::Conflict reaches the toplevel. Indicates which dependencies were incompatible through conflict
and conflicting_dependencies
Potentially raised when a specification is validated.
Used to raise parsing and loading errors
Raised by the DependencyInstaller when a specific gem cannot be found
Represents an error communicating via HTTP.
Raised by Gem::Validator
when something is not right in a gem.
The Specification
class contains the information for a gem. Typically defined in a .gemspec file or a Rakefile, and looks like this:
Gem::Specification.new do |s| s.name = 'example' s.version = '0.1.0' s.licenses = ['MIT'] s.summary = "This is an example!" s.description = "Much longer explanation of the example!" s.authors = ["Ruby Coder"] s.email = 'rubycoder@example.com' s.files = ["lib/example.rb"] s.homepage = 'https://rubygems.org/gems/example' s.metadata = { "source_code_uri" => "https://github.com/example/example" } end
Starting in RubyGems 2.0, a Specification
can hold arbitrary metadata. See metadata
for restrictions on the format and size of metadata items you may add to a specification.
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.
Net::HTTP
exception class. You cannot use Net::HTTPExceptions
directly; instead, you must use its subclasses.
Keyword completion module. This allows partial arguments to be specified and resolved against a list of acceptable values.
