Depends on I468d4eb4 in core. Uses various hacks to trick the test runner into thinking an MW target is in use, when in fact we still use SA targets. Change-Id: If4611307d5d7aaee4af84f86ef82faf9078043b6

|
|
* Add a plugin module or function.
|
|
*
|
|
* Plugins are run after VisualEditor is loaded, but before it is initialized. This allows
|
|
* plugins to add classes and register them with the factories and registries.
|
|
*
|
|
* The parameter to this function can be a ResourceLoader module name or a function.
|
|
*
|
|
* If it's a module name, it will be loaded together with the VisualEditor core modules when
|
|
* VE is loaded. No special care is taken to ensure that the module runs after the VE
|
|
* classes are loaded, so if this is desired, the module should depend on
|
|
* ext.visualEditor.core .
|
|
*
|
|
* If it's a function, it will be invoked once the VisualEditor core modules and any
|
|
* plugin modules registered through this function have been loaded, but before the editor
|
|
* is intialized. The function takes one parameter, which is the ve.init.mw.Target instance
|
|
* that's initializing, and can optionally return a jQuery.Promise . VisualEditor will
|
|
* only be initialized once all promises returned by plugin functions have been resolved.
|
|
*
|
|
* @example
|
|
* // Register ResourceLoader module
|
|
* ve.libs.mw.addPlugin( 'ext.gadget.foobar' );
|
|
*
|
|
* // Register a callback
|
|
* ve.libs.mw.addPlugin( function ( target ) {
|
|
* ve.dm.Foobar = .....
|
|
* } );
|
|
*
|
|
* // Register a callback that loads another script
|
|
* ve.libs.mw.addPlugin( function () {
|
|
* return $.getScript( 'http://example.com/foobar.js' );
|
|
* } );
|
|
*
|
|
* @param {string|Function} plugin Module name or callback that optionally returns a promise
