Eventx design review, status update agenda
  1. Intro, history
  2. Goals
  • Performance
  • Memory usage
  • Size
  • Build to customize
  1. General design overview
  • Events are stateless, nameless
  • Publish events statically or on an instance
  • Subscriptions are managed on the target

WIP IO implementation using transports with send(requestObj, callback(err, data)) and a generic io(requestObj[, callback]) that returns promises.

// sm-io is an alias for sm-io-core and sm-io-xhr. The two modules don't require one another.

Getting an idea of what the expectation of behavior between on() and after() phase of a stopped event is.
var child = new Y.EventTarget({ emitFacade: true }),
parent = new Y.EventTarget({ emitFacade: true }),
grandparent = new Y.EventTarget({ emitFacade: true });
child.addTarget(parent);
parent.addTarget(grandparent);
child.publish('foo', {
defaultFn: function () { console.log("default function"); }
});

Publish a custom event that respects promises returned from the defaultFn.
function promiseFire(data) {
var event = this,
target = this.host;
event._firing = event._firing.then(function () {
return new Y.Promise(function (resolve, reject) {
// Execute on() subscribers
var e = Y.merge({
preventDefault: function () {
this.prevented = true;

YUI 3 data binding. First pass. Supports lots of stuff that I don't have time to document at this very moment. Maybe you can figure it out from the code?
YUI.add('data-bind', function (Y) {
Y.DataBind = function (config) {
if (!Y.Base || !(this instanceof Y.Base)) {
// Being used as a standalone class
this.initializer(config);
// alias instance.destroy() to destructor for convenience
this.destroy = this.destructor;
}
};

Potential patch for 'tap' synthetic event's notifier custom event to allow e.preventDefault() or e.stopPropagation() to have that effect on the subsequent 'click' event.
notifier.handle.evt.fire = function (e) {
var subs = this._subscribers.concat(this._afters),
args = Y.Array(arguments, 0, true),
i, len, halt;
for (i = 0, len = subs.length; i < len; ++i) {
halt = subs[i].notify(args, this);
// stopImmediatePropagation
if (halt === false || e.stopped > 1) {

Patch for 3.6.0pr2 and pr3 DataTable
Y.DataTable.BodyView.prototype._afterModelListChange = function (e) {
var handles = this._eventHandles;
if (handles.dataChange) {
handles.dataChange.detach();
delete handles.dataChange; // <-- this line is missing in the core code
this.bindUI();
}
if (this.tbodyNode) {
