Class App

App is responsible for resource location, and path management.

Adding paths

Additional paths for Templates and Plugins are configured with Configure now. See config/app.php for an example. The App.paths.plugins and App.paths.templates variables are used to configure paths for plugins and templates respectively. All class based resources should be mapped using your application's autoloader.

Inspecting loaded paths

You can inspect the currently loaded paths using App::path('Controller') for example to see loaded controller paths.

It is also possible to inspect paths for plugin classes, for instance, to get the path to a plugin's helpers you would call App::path('View/Helper', 'MyPlugin')

Locating plugins

Plugins can be located with App as well. Using Plugin::path('DebugKit') for example, will give you the full path to the DebugKit plugin.
