The Plugin class should be an object which provides the following methods:
- name - Used during initialisation to order the plugin (based on
the contents of <tt>config.plugins</tt>).
- valid? - Returns true if this plugin can be loaded.
- load_paths - Each path within the returned array will be added to the $LOAD_PATH.
- load - Finally ‘load’ the plugin.
These methods are expected by the Rails::Plugin::Locator and Rails::Plugin::Loader classes. The default implementation returns the lib directory as its load_paths, and evaluates init.rb when load is called.
You can also inspect the about.yml data programmatically:
railties/lib/rails/plugin/loader.rb railties/lib/rails/plugin/locator.rb railties/lib/rails/plugin.rb
