# frozen_string_literal: true module Kernel ## # Use Kernel#gem to activate a specific version of +gem_name+. # # +requirements+ is a list of version requirements that the # specified gem must match, most commonly "= example.version.number". See # Gem::Requirement for how to specify a version requirement. # # If you will be activating the latest version of a gem, there is no need to # call Kernel#gem, Kernel#require will do the right thing for you. # # Kernel#gem returns true if the gem was activated, otherwise false. If the # gem could not be found, didn't match the version requirements, or a # different version was already activated, an exception will be raised. # # Kernel#gem should be called *before* any require statements (otherwise # RubyGems may load a conflicting library version). # # Kernel#gem only loads prerelease versions when prerelease +requirements+ # are given: # # gem 'rake', '>= 1.1.a', '< 2' # # In older RubyGems versions, the environment variable GEM_SKIP could be # used to skip activation of specified gems, for example to test out changes # that haven't been installed yet. Now RubyGems defers to -I and the # RUBYLIB environment variable to skip activation of a gem. # # Example: # # GEM_SKIP=libA:libB ruby -I../libA -I../libB ./mycode.rb def gem(gem_name, *requirements) # :doc: skip_list = (ENV["GEM_SKIP"] || "").split(/:/) raise Gem::LoadError, "skipping #{gem_name}" if skip_list.include? gem_name if gem_name.is_a? Gem::Dependency unless Gem::Deprecate.skip warn "#{Gem.location_of_caller.join ":"}:Warning: Kernel.gem no longer "\ "accepts a Gem::Dependency object, please pass the name "\ "and requirements directly" end requirements = gem_name.requirement gem_name = gem_name.name end dep = Gem::Dependency.new(gem_name, *requirements) loaded = Gem.loaded_specs[gem_name] return false if loaded && dep.matches_spec?(loaded) spec = dep.to_spec if spec if Gem::LOADED_SPECS_MUTEX.owned? spec.activate else Gem::LOADED_SPECS_MUTEX.synchronize { spec.activate } end end end private :gem end
