The code is unaltered (only moved down so that it isn't with the scope of the main @class block). ve.dm.TransactionProcessor.processors. New: * @mixins: Classes mixed into the current class. * @event: Events that can be emitted by a class. These are also inherited by subclasses. (+ @param, @return and @preventable). So ve.Node#event-attach is inherited to ve.dm.BreakNode, just like @method is. * @singleton: Plain objects such as ve, ve.dm, ve.ce were missing documentation causing a tree error. Documented those as a JSDuck singleton, which they but just weren't documented yet. NB: Members of @singleton don't need @static (if present, triggers a compiler warning). * @chainable: Shorthand for "@return this". We were using "@return {classname}" which is ambiguous (returns the same instance or another instance?), @chainable is specifically for "@return this". Creates proper labels in the generated HTML pages. Removed: * @mixin: (not to be confused with @mixins). Not supported by JSDuck. Every class is standalone anyway. Where needed marked them @class + @abstract instead. Change-Id: I6a7c9e8ee8f995731bc205d666167874eb2ebe23

Refactor ve.js utilities and improve documentation Refactor: * ve.indexOf Renamed from ve.inArray. This was named after the jQuery method which in turn has a longer story about why it is so unfortunately named. It doesn't return a boolean, but an index. Hence the native method being called indexOf as well. * ve.bind Renamed from ve.proxy. I considered making it use Function.prototype.bind if available. As it performs better than $.proxy (which doesn't use to the native bind if available). However since bind needs to be bound itself in order to use it detached, it turns out with the "call()" and "bind()" it is slower than the $.proxy shim: http://jsperf.com/function-bind-shim-perf It would've been like this: ve.bind = Function.prototype.bind ? Function.prototype.call.bind( Function.prototype.bind ) : $.proxy; But instead sticking to ve.bind = $.proxy; * ve.extendObject Documented the parts of jQuery.extend that we use. This makes it easier to replace in the future. Documentation: * Added function documentation blocks. * Added annotations to functions that we will be able to remove in the future in favour of the native methods. With "@until + when/how". In this case "ES5". Meaning, whenever we drop support for browsers that don't support ES5. Although in the developer community ES5 is still fairly fresh, browsers have been aware for it long enough that thee moment we're able to drop it may be sooner than we think. The only blocker so far is IE8. The rest of the browsers have had it long enough that the traffic we need to support of non-IE supports it. Misc.: * Removed 'node: true' from .jshintrc since Parsoid is no longer in this repo and thus no more nodejs files. - This unraveled two lint errors: Usage of 'module' and 'console'. (both were considered 'safe globals' due to nodejs, but not in browser code). * Replaced usage (before renaming): - $.inArray -> ve.inArray - Function.prototype.bind -> ve.proxy - Array.isArray -> ve.isArray - [].indexOf -> ve.inArray - $.fn.bind/live/delegate/unbind/die/delegate -> $.fn.on/off Change-Id: Idcf1fa6a685b6ed3d7c99ffe17bd57a7bc586a2c
