modernizr/src/ModernizrProto.js

Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.

define(['tests'], function ( tests ) {
  var ModernizrProto = {
    // The current version, dummy
    _version: 'v3.0.0pre',

    // Any settings that don't work as separate modules
    // can go in here as configuration.
    _config: {
      classPrefix : '',
      enableClasses : true
    },

    // Queue of tests
    _q: [],

    // Stub these for people who are listening
    on: function( test, cb ) {
      // I don't really think people should do this, but we can
      // safe guard it a bit.
      // -- NOTE:: this gets WAY overridden in src/addTest for
      // actual async tests. This is in case people listen to
      // synchronous tests. I would leave it out, but the code
      // to *disallow* sync tests in the real version of this
      // function is actually larger than this.
      setTimeout(function() {
        cb(this[test]);
      }, 0);
    },

    addTest: function( name, fn, options ) {
      tests.push({name : name, fn : fn, options : options });
    },

    addAsyncTest: function (fn) {
      tests.push({name : null, fn : fn});
    }
  };
