Modernizr test for leap motion

modernizrLeap.js

function checkLeap () {
  // Hard dependency on websockets; quick exit if not supported
  if (!Modernizr.websockets) {
    Modernizr.addTest('leap', false);
  }

  // Try and connect to the leap daemon
  var ws = new WebSocket("ws://localhost:6437/");
  ws.onopen = function(event) {
    Modernizr.addTest('leap', true);
  };
  ws.onerror = function(event) {
    Modernizr.addTest('leap', false);
  };
}
checkLeap();

thanks for the response !
i really love the Modernizr.addTest('leap', true); really handy, and clever work on the quick exit, i'll make a real github repo out if and post it to the twitter modernizr, so if someone else need it they could use it.

you confirmed my guesses on the async test, but in this case i could not boil it down to a "simpler" test.

on an other topic, is Modernizr.load deprecated ? i had to use yepnope directly to dynamically load my leap script

Modernizr.load isn’t deprecated yet – but will be from v3.0.0. In v2.x you need to include it explicitly via the builder on http://modernizr.com/download though (in the “Extras” section on the right hand side).

ahh ok, i'm using the plain development version right now, planned on making a modular build later, i guess it is not included in it.

thanks for this wondefull tool by the way :)
