Cloud9 IDE Touch Enabler Monkeypatch

apf_release.prepend.js

/**
 * A proof of concept monkeypatch to make Cloud9 IDE work on a tablet. 
 * Since i'm an extremely lazy bastard I prepended this snippet directly in package/client/js/apf_release.js
 *
 * What does it do?
 * - It fires a doubleclick for a 2-finger tap
 * - It fires a mousewheel up / down event for a 2-finger swipe up / down.
 *
 * How does it work? 
 * Prepend the functions below to <cloud9>/package/client/js/apf_release.js, save, load in tablet.
 * - 2-finger tap a file to open it from the tree
 * - 2-finger swipe up/down to scroll up/down
 *
 * Why 2-finger events?
 * - I Didn't want to mess with any existing bindings.
 *
 * Tested on Galaxy Tab 10.1

// fire mousewheel events for swipe up/down
  document.body.addEventListener('touchmove', function(e) {
     var touch = e.touches[0];
     if ( !touch || e.touches.length < 2 || Math.abs(touch.clientY - startY) < 10) return; // filter small movement
      var direction = (touch.clientY - startY) > 0 ? 'up': 'down',
       me = document.createEvent("MouseEvents"),
       wheelData = (direction == 'up') ? 10 : -10;
       me.initMouseEvent("mousewheel", true, true, window, wheelData, 0,  0,  0,  0, false, false, false, false, 0, touch.target  );

Just started using cloud 9, how should I set this up?

Fantastic work! Any interested in tests from an iPad?

Might also be worth making this available as an extension https://github.com/ajaxorg/cloud9/wiki/List-of-3rd-party-extensions

Two years later and they still haven't made this a standard feature. And the code (assuming it still works the way it is here, or with something just as simple) is right here.

How can you be SO CLOSE to an implementation of functionality on a completely new device and yet not actually take the little leap to get there?
