# frozen_string_literal: true ## # A semi-compatible DSL for the Bundler Gemfile and Isolate gem dependencies # files. # # To work with both the Bundler Gemfile and Isolate formats this # implementation takes some liberties to allow compatibility with each, most # notably in #source. # # A basic gem dependencies file will look like the following: # # source 'https://rubygems.org' # # gem 'rails', '3.2.14a # gem 'devise', '~> 2.1', '>= 2.1.3' # gem 'cancan' # gem 'airbrake' # gem 'pg' # # RubyGems recommends saving this as gem.deps.rb over Gemfile or Isolate. # # To install the gems in this Gemfile use `gem install -g` to install it and # create a lockfile. The lockfile will ensure that when you make changes to # your gem dependencies file a minimum amount of change is made to the # dependencies of your gems. # # RubyGems can activate all the gems in your dependencies file at startup # using the RUBYGEMS_GEMDEPS environment variable or through Gem.use_gemdeps. # See Gem.use_gemdeps for details and warnings. # # See `gem help install` and `gem help gem_dependencies` for further details. class Gem::RequestSet::GemDependencyAPI ENGINE_MAP = { # :nodoc: :jruby => %w[jruby], :jruby_18 => %w[jruby], :jruby_19 => %w[jruby], :maglev => %w[maglev], :mri => %w[ruby], :mri_18 => %w[ruby], :mri_19 => %w[ruby], :mri_20 => %w[ruby], :mri_21 => %w[ruby], :rbx => %w[rbx], :truffleruby => %w[truffleruby], :ruby => %w[ruby rbx maglev truffleruby], :ruby_18 => %w[ruby rbx maglev truffleruby], :ruby_19 => %w[ruby rbx maglev truffleruby], :ruby_20 => %w[ruby rbx maglev truffleruby], :ruby_21 => %w[ruby rbx maglev truffleruby], }.freeze mswin = Gem::Platform.new 'x86-mswin32' mswin64 = Gem::Platform.new 'x64-mswin64' x86_mingw = Gem::Platform.new 'x86-mingw32' x64_mingw = Gem::Platform.new 'x64-mingw32' PLATFORM_MAP = { # :nodoc: :jruby => Gem::Platform::RUBY, :jruby_18 => Gem::Platform::RUBY, :jruby_19 => Gem::Platform::RUBY, :maglev => Gem::Platform::RUBY, :mingw => x86_mingw, :mingw_18 => x86_mingw, :mingw_19 => x86_mingw, :mingw_20 => x86_mingw, :mingw_21 => x86_mingw, :mri => Gem::Platform::RUBY, :mri_18 => Gem::Platform::RUBY, :mri_19 => Gem::Platform::RUBY, :mri_20 => Gem::Platform::RUBY, :mri_21 => Gem::Platform::RUBY, :mswin => mswin, :mswin_18 => mswin, :mswin_19 => mswin, :mswin_20 => mswin, :mswin_21 => mswin, :mswin64 => mswin64, :mswin64_19 => mswin64, :mswin64_20 => mswin64, :mswin64_21 => mswin64, :rbx => Gem::Platform::RUBY, :ruby => Gem::Platform::RUBY, :ruby_18 => Gem::Platform::RUBY, :ruby_19 => Gem::Platform::RUBY, :ruby_20 => Gem::Platform::RUBY, :ruby_21 => Gem::Platform::RUBY, :truffleruby => Gem::Platform::RUBY, :x64_mingw => x64_mingw, :x64_mingw_20 => x64_mingw, :x64_mingw_21 => x64_mingw }.freeze gt_eq_0 = Gem::Requirement.new '>= 0' tilde_gt_1_8_0 = Gem::Requirement.new '~> 1.8.0' tilde_gt_1_9_0 = Gem::Requirement.new '~> 1.9.0' tilde_gt_2_0_0 = Gem::Requirement.new '~> 2.0.0' tilde_gt_2_1_0 = Gem::Requirement.new '~> 2.1.0' VERSION_MAP = { # :nodoc: :jruby => gt_eq_0, :jruby_18 => tilde_gt_1_8_0, :jruby_19 => tilde_gt_1_9_0, :maglev => gt_eq_0, :mingw => gt_eq_0, :mingw_18 => tilde_gt_1_8_0, :mingw_19 => tilde_gt_1_9_0, :mingw_20 => tilde_gt_2_0_0, :mingw_21 => tilde_gt_2_1_0, :mri => gt_eq_0, :mri_18 => tilde_gt_1_8_0, :mri_19 => tilde_gt_1_9_0, :mri_20 => tilde_gt_2_0_0, :mri_21 => tilde_gt_2_1_0, :mswin => gt_eq_0, :mswin_18 => tilde_gt_1_8_0, :mswin_19 => tilde_gt_1_9_0, :mswin_20 => tilde_gt_2_0_0, :mswin_21 => tilde_gt_2_1_0, :mswin64 => gt_eq_0, :mswin64_19 => tilde_gt_1_9_0, :mswin64_20 => tilde_gt_2_0_0, :mswin64_21 => tilde_gt_2_1_0, :rbx => gt_eq_0, :ruby => gt_eq_0, :ruby_18 => tilde_gt_1_8_0, :ruby_19 => tilde_gt_1_9_0, :ruby_20 => tilde_gt_2_0_0, :ruby_21 => tilde_gt_2_1_0, :truffleruby => gt_eq_0, :x64_mingw => gt_eq_0, :x64_mingw_20 => tilde_gt_2_0_0, :x64_mingw_21 => tilde_gt_2_1_0, }.freeze WINDOWS = { # :nodoc: :mingw => :only, :mingw_18 => :only, :mingw_19 => :only, :mingw_20 => :only, :mingw_21 => :only, :mri => :never, :mri_18 => :never, :mri_19 => :never, :mri_20 => :never, :mri_21 => :never, :mswin => :only, :mswin_18 => :only, :mswin_19 => :only, :mswin_20 => :only, :mswin_21 => :only, :mswin64 => :only, :mswin64_19 => :only, :mswin64_20 => :only, :mswin64_21 => :only, :rbx => :never, :ruby => :never, :ruby_18 => :never, :ruby_19 => :never, :ruby_20 => :never, :ruby_21 => :never, :x64_mingw => :only, :x64_mingw_20 => :only, :x64_mingw_21 => :only, }.freeze ## # The gems required by #gem statements in the gem.deps.rb file attr_reader :dependencies ## # A set of gems that are loaded via the +:git+ option to #gem attr_reader :git_set # :nodoc: ## # A Hash containing gem names and files to require from those gems. attr_reader :requires ## # A set of gems that are loaded via the +:path+ option to #gem attr_reader :vendor_set # :nodoc: ## # The groups of gems to exclude from installation attr_accessor :without_groups # :nodoc: ## # Creates a new GemDependencyAPI that will add dependencies to the # Gem::RequestSet +set+ based on the dependency API description in +path+. def initialize(set, path) @set = set @path = path @current_groups = nil @current_platforms = nil @current_repository = nil @dependencies = {} @default_sources = true @git_set = @set.git_set @git_sources = {} @installing = false @requires = Hash.new { |h, name| h[name] = [] } @vendor_set = @set.vendor_set @source_set = @set.source_set @gem_sources = {} @without_groups = [] git_source :github do |repo_name| repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?
