Class: Rails::Generator::Manifest

Manifest captures the actions a generator performs. Instantiate a manifest with an optional target object, hammer it with actions, then replay or rewind on the object of your choice.

Example:

  manifest = Manifest.new { |m|
    m.make_directory '/foo'
    m.create_file '/foo/bar.txt'
  }
  manifest.replay(creator)
  manifest.rewind(destroyer)
