filearts.promise.js

// bluebird.js must be loaded, exposing $window.Promise

angular.module("filearts.promise", [])

.config(["$provide", "$window", function ($provide, $window) {
  
  $provide.decorator("$q", ["$delegate", "$rootScope", function ($delegate, $rootScope) {
    var Promise = $window.Promise;
    var $q = Promise;
    var defer = function () {
      var dfd = {};
      
      dfd.promise = new Promise(function(_resolve, _reject) {
        dfd.resolve = _resolve;     
        dfd.reject = _reject;
      });
    
      return dfd;
    };
    
    $q.defer = defer;
    $q.when = Promise.cast;
    
    return $q;
  }]);
  
}])

.run(["$rootScope", "$window", function ($rootScope, $window) {
  var Promise = $window.Promise;
  
  Promise.setScheduler(function (cb) {
    $rootScope.$evalAsync(cb);
  });
}]);
