Overview

Represents a lazily loaded gem specification, where the full specification is on the source server in rubygems’ “quick” index. The proxy object is to be seeded with what we’re given from the source’s abbreviated index - the full specification will only be fetched when necessary.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &blk) ⇒ Object (private)

def method_missing(method, *args, &blk)
  _remote_specification.send(method, *args, &blk)

Instance Method Details

#<=>(other) ⇒ Object

Compare this specification against another object. Using sort_obj is compatible with Gem::Specification and other Bundler or RubyGems objects. Otherwise, use the default Object comparison.

def <=>(other)
  if other.respond_to?(:sort_obj)
    sort_obj <=> other.sort_obj
  else
    super
  end
end

#__swap__(spec) ⇒ Object

Because Rubyforge cannot be trusted to provide valid specifications once the remote gem is downloaded, the backend specification will be swapped out.

# File 'lib/bundler/remote_specification.rb', line 54

def __swap__(spec)
  SharedHelpers.ensure_same_dependencies(self, dependencies, spec.dependencies)
  @_remote_specification = spec
end

#fetch_platform ⇒ Object

Needed before installs, since the arch matters then and quick specs don’t bother to include the arch in the platform string

def git_version
  return unless loaded_from && source.is_a?(Bundler::Source::Git)
  " #{source.revision[0..6]}"
end

#respond_to?(method, include_all = false) ⇒ Boolean

Returns:

  • (Boolean)

def respond_to?(method, include_all = false)
  super || _remote_specification.respond_to?(method, include_all)
end

#sort_obj ⇒ Array

Create a delegate used for sorting. This strategy is copied from RubyGems 2.23 and ensures that Bundler’s specifications can be compared and sorted with RubyGems’ own specifications.

Returns:

  • (Array) —

    an object you can use to compare and sort this specification against other specifications
