module Kernel # REFACTOR: This should be pulled out into some kind of hacks file. remove_method :gem if 'method' == defined? gem # from gem_prelude.rb on 1.9 ## # 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). # # 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.kind_of?
