// Base AngularJS 1.1.4 Fiddle + jQuery
// http://stackoverflow.com/questions/16368066/angularjs-extending-module-with-own-types-providers

var app = angular.module('myApp', []);

// Provide some basic injectables for testing
app.constant('nameString', 'NAME');
app.constant('ageString', 'AGE');
app.constant('foodString', 'FAVORITE FOOD');

// Create the dialog provider
app.provider('dialog', function($provide, $injector) {
  var dialogs = {};

  this.register = function(name, configFn) {
    // Create a new service
    $provide.factory(name, function($window, $q) {
      dialogs[name] = function() {
        // Get data based on DI injected version of configFn
        var data = $injector.invoke(configFn);
        // faking async here since prompt is really synchronous
        var deferred = $q.defer();
        var response = $window.prompt(data.text);
        deferred.resolve(response);
        return deferred.promise;
      };
      return dialogs[name];
    });
  };

  // Injecting the service itself gives you a function that
  // allows you to access a dialog by name, much like $filter
  this.$get = function() {
    return function(name) {
      return dialogs[name];
    };
  };
});

// Providing dialog injectables via app.config
app.config(function(dialogProvider) {
  dialogProvider.register('askFood', function(foodString) {
    return { text: 'What is your ' + foodString + '?' }
  });
});

// Alternatively, shortcut to accessing the dialogProvider via app.dialog
app.dialog = function(name, configFn) {
  app.config(function(dialogProvider) {
    dialogProvider.register(name, configFn);
  });
};
    
app.dialog('askName', function(nameString) {
  return { text: 'What is your ' + nameString + '?' }
});

app.dialog('askAge', function(ageString) {
  return { text: 'What is your ' + ageString + '?' }
});

app.controller('MainController',
               function($scope, askName, askAge, askFood, dialog) {
  var setLastResponse = function(result) {
