class Bundler::RemoteSpecification

Parent:: Object
Included modules:: Bundler::MatchPlatform, Comparable

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.

new(name, version, platform, spec_fetcher) Show source

# File lib/bundler/remote_specification.rb, line 16
def initialize(name, version, platform, spec_fetcher)
  @name         = name
  @version      = Gem::Version.create version
  @platform     = platform
  @spec_fetcher = spec_fetcher
  @dependencies = nil
end

Public Instance Methods

<=>(other) Show source

# File lib/bundler/remote_specification.rb, line 41
def <=>(other)
  if other.respond_to?(:sort_obj)
    sort_obj <=> other.sort_obj
  else
    super
  end
end

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.

Calls superclass method Object#<=>

__swap__(spec) Show source

# File lib/bundler/remote_specification.rb, line 52
def __swap__(spec)
  SharedHelpers.ensure_same_dependencies(self, dependencies, spec.dependencies)
  @_remote_specification = spec
end

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

dependencies() Show source

# File lib/bundler/remote_specification.rb, line 74
def dependencies
  @dependencies ||= begin
    deps = method_missing(:dependencies)

    # allow us to handle when the specs dependencies are an array of array of string
    # see https://github.com/bundler/bundler/issues/5797
    deps = deps.map {|d| d.is_a?(Gem::Dependency) ? d : Gem::Dependency.new(*d) }

    deps
  end
end

fetch_platform() Show source

# File lib/bundler/remote_specification.rb, line 26
def fetch_platform
  @platform = _remote_specification.platform
end

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

full_name() Show source

# File lib/bundler/remote_specification.rb, line 30
def full_name
  if platform == Gem::Platform::RUBY || platform.nil?
    "#{@name}-#{@version}"
  else
    "#{@name}-#{@version}-#{platform}"
  end
end

git_version() Show source

# File lib/bundler/remote_specification.rb, line 86
def git_version
  return unless loaded_from && source.is_a?(Bundler::Source::Git)
  " #{source.revision[0..6]}"
end

respond_to?(method, include_all = false) Show source

# File lib/bundler/remote_specification.rb, line 107
def respond_to?(method, include_all = false)
  super || _remote_specification.respond_to?(method, include_all)
end

Calls superclass method Object#respond_to?

sort_obj() Show source

# File lib/bundler/remote_specification.rb, line 66
def sort_obj
  [@name, @version, @platform == Gem::Platform::RUBY ? -1 : 1]
end

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.

@see #<=> @see Gem::Specification#sort_obj

@return [Array] an object you can use to compare and sort this

specification against other specifications

to_s() Show source

# File lib/bundler/remote_specification.rb, line 70
def to_s
  "#<#{self.class} name=#{name} version=#{version} platform=#{platform}>"
end
