* Custom gestures
* ==============================
*
* Gesture object
* --------------------
* The object structure of a gesture:

* { name: 'mygesture',
* index: 1337,
* defaults: {
* mygesture_option: true
* }
* handler: function(type, ev, inst) {
* // trigger gesture event
* inst.trigger(this.name, ev);
* }
* }
* @param {String} name
* this should be the name of the gesture, lowercase
* it is also being used to disable/enable the gesture per instance config.
*
* @param {Number} [index=1000]
* the index of the gesture, where it is going to be in the stack of gestures detection
* like when you build an gesture that depends on the drag gesture, it is a good
* idea to place it after the index of the drag gesture.
*
* @param {Object} [defaults={}]
* the default settings of the gesture. these are added to the instance settings,
* and can be overruled per instance. you can also add the name of the gesture,
* but this is also added by default (and set to true).
*
* @param {Function} handler
* this handles the gesture detection of your custom gesture and receives the
* following arguments:
*
* @param {Object} eventData
* event data containing the following properties:
* timeStamp {Number} time the event occurred
* target {HTMLElement} target element
* touches {Array} touches (fingers, pointers, mouse) on the screen
* pointerType {String} kind of pointer that was used. matches ionic.Gestures.POINTER_MOUSE|TOUCH
* center {Object} center position of the touches. contains pageX and pageY
* deltaTime {Number} the total time of the touches in the screen
* deltaX {Number} the delta on x axis we haved moved
* deltaY {Number} the delta on y axis we haved moved
* velocityX {Number} the velocity on the x
* velocityY {Number} the velocity on y
* angle {Number} the angle we are moving
* direction {String} the direction we are moving. matches ionic.Gestures.DIRECTION_UP|DOWN|LEFT|RIGHT
* distance {Number} the distance we haved moved
* scale {Number} scaling of the touches, needs 2 touches
* rotation {Number} rotation of the touches, needs 2 touches *
* eventType {String} matches ionic.Gestures.EVENT_START|MOVE|END
* srcEvent {Object} the source event, like TouchStart or MouseDown *
* startEvent {Object} contains the same properties as above,
* but from the first touch. this is used to calculate
* distances, deltaTime, scaling etc
*
* @param {ionic.Gestures.Instance} inst
* the instance we are doing the detection for. you can get the options from
* the inst.options object and trigger the gesture event by calling inst.trigger
*
*
* Handle gestures
* --------------------
* inside the handler you can get/set ionic.Gestures.detectionic.current. This is the current
* detection sessionic. It has the following properties
* @param {String} name
* contains the name of the gesture we have detected. it has not a real function,
* only to check in other gestures if something is detected.
* like in the drag gesture we set it to 'drag' and in the swipe gesture we can
* check if the current gesture is 'drag' by accessing ionic.Gestures.detectionic.current.name
*
* readonly
* @param {ionic.Gestures.Instance} inst
* the instance we do the detection for
*
* readonly
* @param {Object} startEvent
* contains the properties of the first gesture detection in this sessionic.
* Used for calculations about timing, distance, etc.
*
* readonly
* @param {Object} lastEvent
* contains all the properties of the last gesture detect in this sessionic.
*
* after the gesture detection session has been completed (user has released the screen)
* the ionic.Gestures.detectionic.current object is copied into ionic.Gestures.detectionic.previous,
* this is usefull for gestures like doubletap, where you need to know if the
* previous gesture was a tap
*
* options that have been set by the instance can be received by calling inst.options
*
* You can trigger a gesture event by calling inst.trigger("mygesture", event).
* The first param is the name of your gesture, the second the event argument
*
*
* Register gestures
* --------------------
* When an gesture is added to the ionic.Gestures.gestures object, it is auto registered
* at the setup of the first ionic.Gestures instance. You can also call ionic.Gestures.detectionic.register
* manually and pass your gesture object as a param

/**
* @ngdoc page
* @name tap
* @module ionic
* @description
* On touch devices such as a phone or tablet, some browsers implement a 300ms delay between
* the time the user stops touching the display and the moment the browser executes the
* click. This delay was initially introduced so the browser can know whether the user wants to
* double-tap to zoom in on the webpage. Basically, the browser waits roughly 300ms to see if
* the user is double-tapping, or just tapping on the display once.
*
* Out of the box, Ionic automatically removes the 300ms delay in order to make Ionic apps
* feel more "native" like. Resultingly, other solutions such as
* [fastclick](https://github.com/ftlabs/fastclick) and Angular's
* [ngTouch](https://docs.angularjs.org/api/ngTouch) should not be included, to avoid conflicts.
*
* Some browsers already remove the delay with certain settings, such as the CSS property
* `touch-events: none` or with specific meta tag viewport values. However, each of these
* browsers still handle clicks differently, such as when to fire off or cancel the event
* (like scrolling when the target is a button, or holding a button down).
* For browsers that already remove the 300ms delay, consider Ionic's tap system as a way to
* normalize how clicks are handled across the various devices so there's an expected response
* no matter what the device, platform or version. Additionally, Ionic will prevent
* ghostclicks which even browsers that remove the delay still experience.
*
* In some cases, third-party libraries may also be working with touch events which can interfere
* with the tap system. For example, mapping libraries like Google or Leaflet Maps often implement
* a touch detection system which conflicts with Ionic's tap system.
*
* ### Disabling the tap system
*
* To disable the tap for an element and all of its children elements,
* add the attribute `data-tap-disabled="true"`.
*
* ```html
* <div data-tap-disabled="true">
* <div id="google-map"></div>
* </div>
* ```
*
* ### Additional Notes:
*
* - Ionic tap works with Ionic's JavaScript scrolling
* - Elements can come and go from the DOM and Ionic tap doesn't keep adding and removing
* listeners
* - No "tap delay" after the first "tap" (you can tap as fast as you want, they all click)
* - Minimal events listeners, only being added to document
* - Correct focus in/out on each input type (select, textearea, range) on each platform/device
* - Shows and hides virtual keyboard correctly for each platform/device
* - Works with labels surrounding inputs
* - Does not fire off a click if the user moves the pointer too far
* - Adds and removes an 'activated' css class
* - Multiple [unit tests](https://github.com/driftyco/ionic/blob/master/test/unit/utils/tap.unit.js) for each scenario
*

IONIC TAP
---------------
- Both touch and mouse events are added to the document.body on DOM ready
- If a touch event happens, it does not use mouse event listeners
- On touchend, if the distance between start and end was small, trigger a click
- In the triggered click event, add a 'isIonicTap' property
- The triggered click receives the same x,y coordinates as as the end event
- On document.body click listener (with useCapture=true), only allow clicks with 'isIonicTap'
- Triggering clicks with mouse events work the same as touch, except with mousedown/mouseup
- Tapping inputs is disabled during scrolling

/**
* @ngdoc page
* @name keyboard
* @module ionic
* @description
* On both Android and iOS, Ionic will attempt to prevent the keyboard from
* obscuring inputs and focusable elements when it appears by scrolling them
* into view. In order for this to work, any focusable elements must be within
* a [Scroll View](http://ionicframework.com/docs/api/directive/ionScroll/)
* or a directive such as [Content](http://ionicframework.com/docs/api/directive/ionContent/)
* that has a Scroll View.
*
* It will also attempt to prevent the native overflow scrolling on focus,
* which can cause layout issues such as pushing headers up and out of view.
*
* The keyboard fixes work best in conjunction with the
* [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugins-keyboard),
* although it will perform reasonably well without. However, if you are using
* Cordova there is no reason not to use the plugin.
*
* ### Hide when keyboard shows
*
* To hide an element when the keyboard is open, add the class `hide-on-keyboard-open`.
*
* ```html
* <div class="hide-on-keyboard-open">
* <div id="google-map"></div>
* </div>
* ```
* ----------
*
* ### Plugin Usage
* Information on using the plugin can be found at
* [https://github.com/driftyco/ionic-plugins-keyboard](https://github.com/driftyco/ionic-plugins-keyboard).
*
* ----------
*
* ### Android Notes
* - If your app is running in fullscreen, i.e. you have
* `<preference name="Fullscreen" value="true" />` in your `config.xml` file
* you will need to set `ionic.Platform.isFullScreen = true` manually.
*
* - You can configure the behavior of the web view when the keyboard shows by setting
* [android:windowSoftInputMode](http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode)
* to either `adjustPan`, `adjustResize` or `adjustNothing` in your app's
* activity in `AndroidManifest.xml`. `adjustResize` is the recommended setting
* for Ionic, but if for some reason you do use `adjustPan` you will need to
* set `ionic.Platform.isFullScreen = true`.
*
* ```xml
* <activity android:windowSoftInputMode="adjustResize">
*
* ```
*
* ### iOS Notes
* - If the content of your app (including the header) is being pushed up and
* out of view on input focus, try setting `cordova.plugins.Keyboard.disableScroll(true)`.
* This does **not** disable scrolling in the Ionic scroll view, rather it
* disables the native overflow scrolling that happens automatically as a
* result of focusing on inputs below the keyboard.
*

* @ngdoc directive
* @name ngApp
* @module ng
*
* @element ANY
* @param {angular.Module} ngApp an optional application
* {@link angular.module module} name to load.
* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
* created in "strict-di" mode. This means that the application will fail to invoke functions which
* do not use explicit function annotation (and are thus unsuitable for minification), as described
* in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
* tracking down the root of these bugs.
*
* @description
*
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
* designates the **root element** of the application and is typically placed near the root element
* of the page - e.g. on the `<body>` or `<html>` tags.
*
* Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
* found in the document will be used to define the root element to auto-bootstrap as an
* application. To run multiple applications in an HTML document you must manually bootstrap them using
* {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
*
* You can specify an **AngularJS module** to be used as the root module for the application. This
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
* should contain the application code needed or have dependencies on other modules that will
* contain the code. See {@link angular.module} for more information.
*
* In the example below if the `ngApp` directive were not placed on the `html` element then the
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
* would not be resolved to `3`.
*
* `ngApp` is the easiest, and most common way to bootstrap an application.
*
<example module="ngAppDemo">
<file name="index.html">
<div ng-controller="ngAppDemoController">
I can add: {{a}} + {{b}} = {{ a+b }}
</div>
</file>
<file name="script.js">
angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
$scope.a = 1;
$scope.b = 2;
});
</file>
</example>
*
* Using `ngStrictDi`, you would see something like this:
*
<example ng-app-included="true">
<file name="index.html">
<div ng-app="ngAppStrictDemo" ng-strict-di>
<div ng-controller="GoodController1">
I can add: {{a}} + {{b}} = {{ a+b }}
<p>This renders because the controller does not fail to
instantiate, by using explicit annotation style (see
script.js for details)
</p>
</div>
<div ng-controller="GoodController2">
Name: <input ng-model="name"><br />
Hello, {{name}}!
<p>This renders because the controller does not fail to
instantiate, by using explicit annotation style
(see script.js for details)
</p>
</div>
<div ng-controller="BadController">
I can add: {{a}} + {{b}} = {{ a+b }}
<p>The controller could not be instantiated, due to relying
on automatic function annotations (which are disabled in
strict mode). As such, the content of this section is not
interpolated, and there should be an error in your web console.
</p>
</div>

*
* The `angular.module` is a global place for creating, registering and retrieving Angular
* modules.
* All modules (angular core or 3rd party) that should be available to an application must be
* registered using this mechanism.
*
* When passed two or more arguments, a new module is created. If passed only one argument, an
* existing module (the name passed as the first argument to `module`) is retrieved.
*
*
* # Module
*
* A module is a collection of services, directives, controllers, filters, and configuration information.
* `angular.module` is used to configure the {@link auto.$injector $injector}.
*
* ```js
* // Create a new module
* var myModule = angular.module('myModule', []);
*
* // register a new service
* myModule.value('appName', 'MyCoolApp');
*
* // configure existing services inside initialization blocks.
* myModule.config(['$locationProvider', function($locationProvider) {
* // Configure existing providers
* $locationProvider.hashPrefix('!');
* }]);
* ```
*
* Then you can create an injector and load your modules like this:
*
* ```js
* var injector = angular.injector(['ng', 'myModule'])
* ```
*
* However it's more likely that you'll just use
* {@link ng.directive:ngApp ngApp} or
* {@link angular.bootstrap} to simplify this process for you.
*
* @param {!string} name The name of the module to create or retrieve.
* @param {!Array.<string>=} requires If specified then new module is being created. If
* unspecified then the module is being retrieved for further configuration.
* @param {Function=} configFn Optional configuration function for the module. Same as
* {@link angular.Module#config Module#config()}.
* @returns {module} new module with the {@link angular.Module} api.

* @ngdoc function
* @name angular.element
* @module ng
* @kind function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
*
* If jQuery is available, `angular.element` is an alias for the
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
*
* <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
* Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
* commonly needed functionality with the goal of having a very small footprint.</div>
*
* To use jQuery, simply load it before `DOMContentLoaded` event fired.
*
* <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
* jqLite; they are never raw DOM references.</div>
*
* ## Angular's jqLite
* jqLite provides only the following jQuery methods:
*
* - [`addClass()`](http://api.jquery.com/addClass/)
* - [`after()`](http://api.jquery.com/after/)
* - [`append()`](http://api.jquery.com/append/)
* - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
* - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors
* - [`clone()`](http://api.jquery.com/clone/)
* - [`contents()`](http://api.jquery.com/contents/)
* - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`
* - [`data()`](http://api.jquery.com/data/)
* - [`detach()`](http://api.jquery.com/detach/)
* - [`empty()`](http://api.jquery.com/empty/)
* - [`eq()`](http://api.jquery.com/eq/)
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
* - [`hasClass()`](http://api.jquery.com/hasClass/)
* - [`html()`](http://api.jquery.com/html/)
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
* - [`prepend()`](http://api.jquery.com/prepend/)
* - [`prop()`](http://api.jquery.com/prop/)
* - [`ready()`](http://api.jquery.com/ready/)
* - [`remove()`](http://api.jquery.com/remove/)
* - [`removeAttr()`](http://api.jquery.com/removeAttr/)
* - [`removeClass()`](http://api.jquery.com/removeClass/)
* - [`removeData()`](http://api.jquery.com/removeData/)
* - [`replaceWith()`](http://api.jquery.com/replaceWith/)
* - [`text()`](http://api.jquery.com/text/)
* - [`toggleClass()`](http://api.jquery.com/toggleClass/)
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
* - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
* - [`val()`](http://api.jquery.com/val/)
* - [`wrap()`](http://api.jquery.com/wrap/)
*
* ## jQuery/jqLite Extras
* Angular also provides the following additional methods and events to both jQuery and jqLite:
*
* ### Events
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
* element before it is removed.
*
* ### Methods
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
* retrieves controller associated with the `ngController` directive. If `name` is provided as
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
* `'ngModel'`).
* - `injector()` - retrieves the injector of the current element or its parent.
* - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
* element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
* be enabled.
* - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
* current element. This getter should be used only on elements that contain a directive which starts a new isolate
* scope. Calling `scope()` on this element always returns the original non-isolate scope.
* Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
* parent element is reached.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.

* @ngdoc function
* @module ng
* @name angular.injector
* @kind function
*
* @description
* Creates an injector object that can be used for retrieving services as well as for
* dependency injection (see {@link guide/di dependency injection}).
*
* @param {Array.<string|Function>} modules A list of module functions or their aliases. See
* {@link angular.module}. The `ng` module must be explicitly added.
* @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
* disallows argument name annotation inference.
* @returns {injector} Injector object. See {@link auto.$injector $injector}.
*
* @example
* Typical usage
* ```js
* // create an injector
* var $injector = angular.injector(['ng']);
*
* // use the injector to kick off your application
* // use the type inference to auto inject arguments, or use implicit injection
* $injector.invoke(function($rootScope, $compile, $document) {
* $compile($document)($rootScope);
* $rootScope.$digest();
* });
* ```
*
* Sometimes you want to get access to the injector of a currently running Angular app
* from outside Angular. Perhaps, you want to inject and compile some markup after the
* application has been bootstrapped. You can do this using the extra `injector()` added
* to JQuery/jqLite elements. See {@link angular.element}.
*
* *This is fairly rare but could be the case if a third party library is injecting the
* markup.*
*
* In the following example a new block of HTML containing a `ng-controller`
* directive is added to the end of the document body by JQuery. We then compile and link
* it into the current AngularJS scope.
*
* ```js
* var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
* $(document.body).append($div);
*
* angular.element(document).injector().invoke(function($compile) {
* var scope = angular.element($div).scope();
* $compile($div)(scope);
* });
* ```

* @name $injector
*
* @description
*
* `$injector` is used to retrieve object instances as defined by
* {@link auto.$provide provider}, instantiate types, invoke methods,
* and load modules.
*
* The following always holds true:
*
* ```js
* var $injector = angular.injector();
* expect($injector.get('$injector')).toBe($injector);
* expect($injector.invoke(function($injector) {
* return $injector;
* })).toBe($injector);
* ```
*
* # Injection Function Annotation
*
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
* following are all valid ways of annotating function with injection arguments and are equivalent.
*
* ```js
* // inferred (only works if code not minified/obfuscated)
* $injector.invoke(function(serviceA){});
*
* // annotated
* function explicit(serviceA) {};
* explicit.$inject = ['serviceA'];
* $injector.invoke(explicit);
*
* // inline
* $injector.invoke(['serviceA', function(serviceA){}]);
* ```
*
* ## Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition
* can then be parsed and the function arguments can be extracted. This method of discovering
* annotations is disallowed when the injector is in strict mode.
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
* argument names.
*
* ## `$inject` Annotation
* By adding an `$inject` property onto a function the injection parameters can be specified.
*
* ## Inline
* As an array of injection names, where the last item in the array is the function to call.

/**
* @ngdoc method
* @name $injector#annotate
*
* @description
* Returns an array of service names which the function is requesting for injection. This API is
* used by the injector to determine which services need to be injected into the function when the
* function is invoked. There are three ways in which the function can be annotated with the needed
* dependencies.
*
* # Argument names
*
* The simplest form is to extract the dependencies from the arguments of the function. This is done
* by converting the function into a string using `toString()` method and extracting the argument
* names.
* ```js
* // Given
* function MyController($scope, $route) {
* // ...
* }
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* You can disallow this method by using strict injection mode.
*
* This method does not work with code minification / obfuscation. For this reason the following
* annotation strategies are supported.
*
* # The `$inject` property
*
* If a function has an `$inject` property and its value is an array of strings, then the strings
* represent names of services to be injected into the function.
* ```js
* // Given
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
* // ...
* }
* // Define function dependencies
* MyController['$inject'] = ['$scope', '$route'];
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* # The array notation
*
* It is often desirable to inline Injected functions and that's when setting the `$inject` property
* is very inconvenient. In these situations using the array notation to specify the dependencies in
* a way that survives minification is a better choice:
*
* ```js
* // We wish to write this (not minification / obfuscation safe)
* injector.invoke(function($compile, $rootScope) {
* // ...
* });
*
* // We are forced to write break inlining
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
* // ...
* };
* tmpFn.$inject = ['$compile', '$rootScope'];
* injector.invoke(tmpFn);
*
* // To better support inline function the inline annotation is supported
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
* // ...
* }]);
*
* // Therefore
* expect(injector.annotate(
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
* ).toEqual(['$compile', '$rootScope']);
* ```
*
* @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
* be retrieved as described above.
*
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
*
* @returns {Array.<string>} The names of the services which the function requires.

/**
* @ngdoc service
* @name $provide
*
* @description
*
* The {@link auto.$provide $provide} service has a number of methods for registering components
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on
* {@link angular.Module}.
*
* An Angular **service** is a singleton object created by a **service factory**. These **service
* factories** are functions which, in turn, are created by a **service provider**.
* The **service providers** are constructor functions. When instantiated they must contain a
* property called `$get`, which holds the **service factory** function.
*
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the
* correct **service provider**, instantiating it and then calling its `$get` **service factory**
* function to get the instance of the **service**.
*
* Often services have no configuration options and there is no need to add methods to the service
* provider. The provider will be no more than a constructor function with a `$get` property. For
* these cases the {@link auto.$provide $provide} service has additional helper methods to register
* services without specifying a provider.
*
* * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the
* {@link auto.$injector $injector}
* * {@link auto.$provide#constant constant(obj)} - registers a value/object that can be accessed by
* providers and services.
* * {@link auto.$provide#value value(obj)} - registers a value/object that can only be accessed by
* services, not providers.
* * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`,
* that will be wrapped in a **service provider** object, whose `$get` property will contain the
* given factory function.
* * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class`
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate
* a new object using the given constructor function.
*
* See the individual methods for more information and examples.
*/
/**
* @ngdoc method
* @name $provide#provider
* @description
*
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
* are constructor functions, whose instances are responsible for "providing" a factory for a
* service.
*
* Service provider names start with the name of the service they provide followed by `Provider`.
* For example, the {@link ng.$log $log} service has a provider called
* {@link ng.$logProvider $logProvider}.
*
* Service provider objects can have additional methods which allow configuration of the provider
* and its service. Importantly, you can configure what kind of service is created by the `$get`
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
* method {@link ng.$logProvider#debugEnabled debugEnabled}
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
* console or not.
*
* @param {string} name The name of the instance. NOTE: the provider will be available under `name +
'Provider'` key.
* @param {(Object|function())} provider If the provider is:
*
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
* - `Constructor`: a new instance of the provider will be created using
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
*
* @returns {Object} registered provider instance
* @example
*
* The following example shows how to create a simple event tracking service and register it using
* {@link auto.$provide#provider $provide.provider()}.
*
* ```js
* // Define the eventTracker provider
* function EventTrackerProvider() {
* var trackingUrl = '/track';
*
* // A provider method for configuring where the tracked events should been saved
* this.setTrackingUrl = function(url) {
* trackingUrl = url;
* };
*
* // The service factory function
* this.$get = ['$http', function($http) {
* var trackedEvents = {};
* return {
* // Call this to track an event
* event: function(event) {
* var count = trackedEvents[event] || 0;
* count += 1;
* trackedEvents[event] = count;
* return count;
* },
* // Call this to save the tracked events to the trackingUrl
* save: function() {
* $http.post(trackingUrl, trackedEvents);
* }
* };
* }];
* }
*
* describe('eventTracker', function() {
* var postSpy;
*
* beforeEach(module(function($provide) {
* // Register the eventTracker provider
* $provide.provider('eventTracker', EventTrackerProvider);
* }));
*
* beforeEach(module(function(eventTrackerProvider) {
* // Configure eventTracker provider
* eventTrackerProvider.setTrackingUrl('/custom-track');
* }));
*
* it('tracks events', inject(function(eventTracker) {
* expect(eventTracker.event('login')).toEqual(1);
* expect(eventTracker.event('login')).toEqual(2);
* }));
*
* it('saves to the tracking url', inject(function(eventTracker, $http) {
* postSpy = spyOn($http, 'post');
* eventTracker.event('login');
* eventTracker.save();
* expect(postSpy).toHaveBeenCalled();
* expect(postSpy.mostRecentCall.args[0]).not.toEqual('/track');
* expect(postSpy.mostRecentCall.args[0]).toEqual('/custom-track');

*
* `yOffset` can be specified in various ways:
* - **number**: A fixed number of pixels to be used as offset.<br /><br />
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
* a number representing the offset (in pixels).<br /><br />
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
* the top of the page to the element's bottom will be used as offset.<br />
* **Note**: The element will be taken into account only as long as its `position` is set to
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
* their height and/or positioning according to the viewport's size.

* **Note:** This document is an in-depth reference of all directive options.
* For a gentle introduction to directives with examples of common use cases,

* </div>
*
* ## Comprehensive Directive API
*
* There are many different options for a directive.
*
* The difference resides in the return value of the factory function.
* You can either return a "Directive Definition Object" (see below) that defines the directive properties,
* or just the `postLink` function (all other properties will have the default values).
*
* <div class="alert alert-success">
* **Best Practice:** It's recommended to use the "directive definition object" form.
* </div>
*
* Here's an example directive declared with a Directive Definition Object:
*
* ```js
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* priority: 0,
* template: '<div></div>', // or // function(tElement, tAttrs) { ... },
* // or
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
* transclude: false,
* restrict: 'A',
* templateNamespace: 'html',
* scope: false,
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
* controllerAs: 'stringAlias',
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
* compile: function compile(tElement, tAttrs, transclude) {
* return {
* pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* post: function postLink(scope, iElement, iAttrs, controller) { ... }
* }
* // or
* // return function postLink( ... ) { ... }
* },
* // or
* // link: {
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* // post: function postLink(scope, iElement, iAttrs, controller) { ... }
* // }
* // or
* // link: function postLink( ... ) { ... }
* };
* return directiveDefinitionObject;
* });
* ```
*
* <div class="alert alert-warning">
* **Note:** Any unspecified options will use the default value. You can see the default values below.
* </div>
*
* Therefore the above can be simplified as:
*
* ```js
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* link: function postLink(scope, iElement, iAttrs) { ... }
* };
* return directiveDefinitionObject;
* // or
* // return function postLink(scope, iElement, iAttrs) { ... }
* });
* ```
*
*
*
* ### Directive Definition Object
*
* The directive definition object provides instructions to the {@link ng.$compile
* compiler}. The attributes are:
*
* #### `multiElement`
* When this property is set to true, the HTML compiler will collect DOM nodes between
* nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
* together as the directive elements. It is recommended that this feature be used on directives
* which are not strictly behavioural (such as {@link ngClick}), and which
* do not manipulate or replace child nodes (such as {@link ngInclude}).
*
* #### `priority`
* When there are multiple directives defined on a single DOM element, sometimes it
* is necessary to specify the order in which the directives are applied. The `priority` is used
* to sort the directives before their `compile` functions get called. Priority is defined as a
* number. Directives with greater numerical `priority` are compiled first. Pre-link functions
* are also run in priority order, but post-link functions are run in reverse order. The order
* of directives with the same priority is undefined. The default priority is `0`.
*
* #### `terminal`
* If set to true then the current `priority` will be the last set of directives
* which will execute (any directives at the current priority will still execute
* as the order of execution on same `priority` is undefined). Note that expressions
* and other directives used in the directive's template will also be excluded from execution.
*
* #### `scope`
* **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
* same element request a new scope, only one new scope is created. The new scope rule does not
* apply for the root of the template since the root of the template always gets a new scope.
*
* **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
* normal scope in that it does not prototypically inherit from the parent scope. This is useful
* when creating reusable components, which should not accidentally read or modify data in the
* parent scope.
*
* The 'isolate' scope takes an object hash which defines a set of local scope properties
* derived from the parent scope. These local properties are useful for aliasing values for
* templates. Locals definition is a hash of local scope property to its source:
*
* * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
* always a string since DOM attributes are strings. If no `attr` name is specified then the
* attribute name is assumed to be the same as the local name.
* Given `<widget my-attr="hello {{name}}">` and widget definition
* of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
* the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
* `localName` property on the widget scope. The `name` is read from the parent scope (not
* component scope).
*
* * `=` or `=attr` - set up bi-directional binding between a local scope property and the
* parent scope property of name defined via the value of the `attr` attribute. If no `attr`
* name is specified then the attribute name is assumed to be the same as the local name.
* Given `<widget my-attr="parentModel">` and widget definition of
* `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
* value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
* in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
* scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
* can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If
* you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use
* `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).
*
* * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
* If no `attr` name is specified then the attribute name is assumed to be the same as the
* local name. Given `<widget my-attr="count = count + value">` and widget definition of
* `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
* a function wrapper for the `count = count + value` expression. Often it's desirable to
* pass data from the isolated scope via an expression to the parent scope, this can be
* done by passing a map of local variable names and values into the expression wrapper fn.
* For example, if the expression is `increment(amount)` then we can specify the amount value
* by calling the `localFn` as `localFn({amount: 22})`.
*
*
* #### `bindToController`
* When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will
* allow a component to have its properties bound to the controller, rather than to scope. When the controller
* is instantiated, the initial values of the isolate scope bindings are already available.
*
* #### `controller`
* Controller constructor function. The controller is instantiated before the
* pre-linking phase and it is shared with other directives (see
* `require` attribute). This allows the directives to communicate with each other and augment
* each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
*
* * `$scope` - Current scope associated with the element
* * `$element` - Current element
* * `$attrs` - Current attributes object for the element
* * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
* `function([scope], cloneLinkingFn, futureParentElement)`.
* * `scope`: optional argument to override the scope.
* * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.
* * `futureParentElement`:
* * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
* * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
* * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
* and when the `cloneLinkinFn` is passed,
* as those elements need to created and cloned in a special way when they are defined outside their
* usual containers (e.g. like `<svg>`).
* * See also the `directive.templateNamespace` property.
*
*
* #### `require`
* Require another directive and inject its controller as the fourth argument to the linking function. The
* `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
* injected argument will be an array in corresponding order. If no such directive can be
* found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:
*
* * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
* * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
* * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
* * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
* * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
* `null` to the `link` fn if not found.
* * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
* `null` to the `link` fn if not found.
*
*
* #### `controllerAs`
* Controller alias at the directive scope. An alias for the controller so it
* can be referenced at the directive template. The directive needs to define a scope for this
* configuration to be used. Useful in the case when directive is used as component.
*
*
* #### `restrict`
* String of subset of `EACM` which restricts the directive to a specific directive
* declaration style. If omitted, the defaults (elements and attributes) are used.
*
* * `E` - Element name (default): `<my-directive></my-directive>`
* * `A` - Attribute (default): `<div my-directive="exp"></div>`
* * `C` - Class: `<div class="my-directive: exp;"></div>`
* * `M` - Comment: `<!-- directive: my-directive exp -->`
*
*
* #### `templateNamespace`
* String representing the document type used by the markup in the template.
* AngularJS needs this information as those elements need to be created and cloned
* in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
*
* * `html` - All root nodes in the template are HTML. Root nodes may also be
* top-level elements such as `<svg>` or `<math>`.
* * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
* * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
*
* If no `templateNamespace` is specified, then the namespace is considered to be `html`.
*
* #### `template`
* HTML markup that may:
* * Replace the contents of the directive's element (default).
* * Replace the directive's element itself (if `replace` is true - DEPRECATED).
* * Wrap the contents of the directive's element (if `transclude` is true).
*
* Value may be:
*
* * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
* * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
* function api below) and returns a string value.
*
*
* #### `templateUrl`
* This is similar to `template` but the template is loaded from the specified URL, asynchronously.
*
* Because template loading is asynchronous the compiler will suspend compilation of directives on that element
* for later when the template has been resolved. In the meantime it will continue to compile and link
* sibling and parent elements as though this element had not contained any directives.
*
* The compiler does not suspend the entire compilation to wait for templates to be loaded because this
* would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
* case when only one deeply nested directive has `templateUrl`.
*
* Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
*
* You can specify `templateUrl` as a string representing the URL or as a function which takes two
* arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
* a string value representing the url. In either case, the template URL is passed through {@link
* $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
*
*
* #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
* specify what the template should replace. Defaults to `false`.
*
* * `true` - the template will replace the directive's element.
* * `false` - the template will replace the contents of the directive's element.
*
* The replacement process migrates all of the attributes / classes from the old element to the new
* one. See the {@link guide/directive#template-expanding-directive
* Directives Guide} for an example.
*
* There are very few scenarios where element replacement is required for the application function,
* the main one being reusable custom components that are used within SVG contexts
* (because SVG doesn't work with custom elements in the DOM tree).
*
* #### `transclude`
* Extract the contents of the element where the directive appears and make it available to the directive.
* The contents are compiled and provided to the directive as a **transclusion function**. See the
* {@link $compile#transclusion Transclusion} section below.
*
* There are two kinds of transclusion depending upon whether you want to transclude just the contents of the
* directive's element or the entire element:
*
* * `true` - transclude the content (i.e. the child nodes) of the directive's element.
* * `'element'` - transclude the whole of the directive's element including any directives on this
* element that defined at a lower priority than this directive. When used, the `template`
* property is ignored.
*
*
* #### `compile`
*
* ```js
* function compile(tElement, tAttrs, transclude) { ... }
* ```
*
* The compile function deals with transforming the template DOM. Since most directives do not do
* template transformation, it is not used often. The compile function takes the following arguments:
*
* * `tElement` - template element - The element where the directive has been declared. It is
* safe to do template transformation on the element and child elements only.
*
* * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
* between all directive compile functions.
*
* * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
*
* <div class="alert alert-warning">
* **Note:** The template instance and the link instance may be different objects if the template has
* been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
* apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
* should be done in a linking function rather than in a compile function.
* </div>
* <div class="alert alert-warning">
* **Note:** The compile function cannot handle directives that recursively use themselves in their
* own templates or compile functions. Compiling these directives results in an infinite loop and a
* stack overflow errors.
*
* This can be avoided by manually using $compile in the postLink function to imperatively compile
* a directive's template instead of relying on automatic template compilation via `template` or
* `templateUrl` declaration or manual compilation inside the compile function.
* </div>
*
* <div class="alert alert-error">
* **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
* e.g. does not know about the right outer scope. Please use the transclude function that is passed
* to the link function instead.
* </div>
* A compile function can have a return value which can be either a function or an object.
*
* * returning a (post-link) function - is equivalent to registering the linking function via the
* `link` property of the config object when the compile function is empty.
*
* * returning an object with function(s) registered via `pre` and `post` properties - allows you to
* control when a linking function should be called during the linking phase. See info about
* pre-linking and post-linking functions below.
*
*
* #### `link`
* This property is used only if the `compile` property is not defined.
*
* ```js
* function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
* ```
*
* The link function is responsible for registering DOM listeners as well as updating the DOM. It is
* executed after the template has been cloned. This is where most of the directive logic will be
* put.
*
* * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
* directive for registering {@link ng.$rootScope.Scope#$watch watches}.
*
* * `iElement` - instance element - The element where the directive is to be used. It is safe to
* manipulate the children of the element only in `postLink` function since the children have
* already been linked.
*
* * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
* between all directive linking functions.
*
* * `controller` - a controller instance - A controller instance if at least one directive on the
* element defines a controller. The controller is shared among all the directives, which allows
* the directives to use the controllers as a communication channel.
*
* * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
* This is the same as the `$transclude`
* parameter of directive controllers, see there for details.
* `function([scope], cloneLinkingFn, futureParentElement)`.
*
* #### Pre-linking function
*
* Executed before the child elements are linked. Not safe to do DOM transformation since the
* compiler linking function will fail to locate the correct elements for linking.
*
* #### Post-linking function
*
* Executed after the child elements are linked.
*
* Note that child elements that contain `templateUrl` directives will not have been compiled
* and linked since they are waiting for their template to load asynchronously and their own
* compilation and linking has been suspended until that occurs.
*
* It is safe to do DOM transformation in the post-linking function on elements that are not waiting
* for their async templates to be resolved.
*
*
* ### Transclusion
*
* Transclusion is the process of extracting a collection of DOM element from one part of the DOM and
* copying them to another part of the DOM, while maintaining their connection to the original AngularJS
* scope from where they were taken.
*
* Transclusion is used (often with {@link ngTransclude}) to insert the
* original contents of a directive's element into a specified place in the template of the directive.
* The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
* content has access to the properties on the scope from which it was taken, even if the directive
* has isolated scope.
* See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
*
* This makes it possible for the widget to have private state for its template, while the transcluded
* content has access to its originating scope.
*
* <div class="alert alert-warning">
* **Note:** When testing an element transclude directive you must not place the directive at the root of the
* DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
* Testing Transclusion Directives}.
* </div>
*
* #### Transclusion Functions
*
* When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
* function** to the directive's `link` function and `controller`. This transclusion function is a special
* **linking function** that will return the compiled contents linked to a new transclusion scope.
*
* <div class="alert alert-info">
* If you are just using {@link ngTransclude} then you don't need to worry about this function, since
* ngTransclude will deal with it for us.
* </div>
*
* If you want to manually control the insertion and removal of the transcluded content in your directive
* then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
* object that contains the compiled DOM, which is linked to the correct transclusion scope.
*
* When you call a transclusion function you can pass in a **clone attach function**. This function accepts
* two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
* content and the `scope` is the newly created transclusion scope, to which the clone is bound.
*
* <div class="alert alert-info">
* **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function
* since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
* </div>
*
* It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
* attach function**:
*
* ```js
* var transcludedContent, transclusionScope;
*
* $transclude(function(clone, scope) {
* element.append(clone);
* transcludedContent = clone;
* transclusionScope = scope;
* });
* ```
*
* Later, if you want to remove the transcluded content from your DOM then you should also destroy the
* associated transclusion scope:
*
* ```js
* transcludedContent.remove();
* transclusionScope.$destroy();
* ```
*
* <div class="alert alert-info">
* **Best Practice**: if you intend to add and remove transcluded content manually in your directive
* (by calling the transclude function to get the DOM and and calling `element.remove()` to remove it),
* then you are also responsible for calling `$destroy` on the transclusion scope.
* </div>
*
* The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
* automatically destroy their transluded clones as necessary so you do not need to worry about this if
* you are simply using {@link ngTransclude} to inject the transclusion into your directive.
*
*
* #### Transclusion Scopes
*
* When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
* scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
* when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
* was taken.
*
* For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
* like this:
*
* ```html
* <div ng-app>
* <div isolate>
* <div transclusion>
* </div>
* </div>
* </div>
* ```
*
* The `$parent` scope hierarchy will look like this:
*
* ```
* - $rootScope
* - isolate
* - transclusion
* ```
*
* but the scopes will inherit prototypically from different scopes to their `$parent`.
*
* ```
* - $rootScope
* - transclusion
* - isolate
* ```
*
*
* ### Attributes
*
* The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
* `link()` or `compile()` functions. It has a variety of uses.
*
* accessing *Normalized attribute names:*
* Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
* the attributes object allows for normalized access to
* the attributes.
*
* * *Directive inter-communication:* All directives share the same instance of the attributes
* object which allows the directives to use the attributes object as inter directive
* communication.
*
* * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
* allowing other directives to read the interpolated value.
*
* * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
* the only way to easily get the actual value because during the linking phase the interpolation
* hasn't been evaluated yet and so the value is at this time set to `undefined`.
*
* ```js
* function linkingFn(scope, elm, attrs, ctrl) {
* // get the attribute value
* console.log(attrs.ngModel);
*
* // change the attribute
* attrs.$set('ngModel', 'new value');
*
* // observe changes to interpolated attribute
* attrs.$observe('ngModel', function(value) {
* console.log('ngModel has changed value to ' + value);
* });
* }
* ```
*
* ## Example
*
* <div class="alert alert-warning">
* **Note**: Typically directives are registered with `module.directive`. The example below is
* to illustrate how `$compile` works.
* </div>
*
<example module="compileExample">
<file name="index.html">
<script>
angular.module('compileExample', [], function($compileProvider) {
// configure new 'compile' directive by passing a directive
// factory function. The factory function injects the '$compile'
$compileProvider.directive('compile', function($compile) {
// directive factory creates a link function
return function(scope, element, attrs) {
scope.$watch(
function(scope) {
// watch the 'compile' expression for changes
return scope.$eval(attrs.compile);
},
function(value) {
// when the 'compile' expression changes
// assign it into the current DOM
element.html(value);
// compile the new DOM and link it to the current
// scope.
// NOTE: we only compile .childNodes so that
// we don't get into infinite loop compiling ourselves
$compile(element.contents())(scope);
}
);
};
});
})
.controller('GreeterController', ['$scope', function($scope) {
$scope.name = 'Angular';
$scope.html = 'Hello {{name}}';
}]);
</script>
<div ng-controller="GreeterController">
<input ng-model="name"> <br>
<textarea ng-model="html"></textarea> <br>
<div compile="html"></div>
</div>
</file>
<file name="protractor.js" type="protractor">
it('should auto compile', function() {
var textarea = $('textarea');
var output = $('div[compile]');
// The initial state reads 'Hello Angular'.
expect(output.getText()).toBe('Hello Angular');
textarea.clear();
textarea.sendKeys('{{name}}!');
expect(output.getText()).toBe('Angular!');
});
</file>
</example>
*
*
* @param {string|DOMElement} element Element or HTML string to compile into a template function.
* @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
*
* <div class="alert alert-error">
* **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
* e.g. will not use the right outer scope. Please pass the transclude function as a
* `parentBoundTranscludeFn` to the link function instead.
* </div>
*
* @param {number} maxPriority only apply directives lower than given priority (Only effects the
* root element(s), not their children)
* @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
* called as: <br> `cloneAttachFn(clonedElement, scope)` where:
*
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
* * `scope` - is the current scope with which the linking function is working with.
*
* * `options` - An optional object hash with linking options. If `options` is provided, then the following
* keys may be used to control linking behavior:
*
* * `parentBoundTranscludeFn` - the transclude function made available to
* directives; if given, it will be passed through to the link functions of
* directives found in `element` during compilation.
* * `transcludeControllers` - an object hash with keys that map controller names
* to controller instances; if given, it will make the controllers
* available to directives.
* * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
* the cloned elements; only needed for transcludes that are allowed to contain non html
* elements (e.g. SVG elements). See also the directive.controller property.
*
* Calling the linking function returns the element of the template. It is either the original
* element passed in, or the clone of the element if the `cloneAttachFn` is provided.
*
* After linking the view is not updated until after a call to $digest which typically is done by
* Angular automatically.
*
* If you need access to the bound view, there are two ways to do it:
*
* - If you are not asking the linking function to clone the template, create the DOM element(s)
* before you send them to the compiler and keep this reference around.
* ```js
* var element = $compile('<p>{{total}}</p>')(scope);
* ```
*
* - if on the other hand, you need the element to be cloned, the view reference from the original
* example would not point to the clone, but rather to the original template that was cloned. In
* this case, you can access the clone via the cloneAttachFn:
* ```js
* var templateElement = angular.element('<p>{{total}}</p>'),
* scope = ....;
*
* var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
* //attach the clone to DOM document at the right place
* });
*
* //now we have reference to the cloned DOM via `clonedElement`
* ```
*

* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

* @description
* Any uncaught exception in angular expressions is delegated to this service.
* The default implementation simply delegates to `$log.error` which logs it into
* the browser console.
*
* In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
* {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
*
* ## Example:
*
* ```js
* angular.module('exceptionOverride', []).factory('$exceptionHandler', function() {
* return function(exception, cause) {
* exception.message += ' (caused by "' + cause + '")';
* throw exception;
* };
* });
* ```
*
* This example will override the normal action of `$exceptionHandler`, to make angular
* exceptions fail hard when they happen, instead of just logging to the console.
*
* <hr />
* Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
* methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
* (unless executed during a digest).
*
* If you wish, you can manually delegate exceptions, e.g.
* `try { ... } catch(e) { $exceptionHandler(e); }`
*
* @param {Error} exception Exception associated with the error.
* @param {string=} cause optional information about the context in which
* the error was thrown.

* @requires $injector
*
* @description
* The `$http` service is a core Angular service that facilitates communication with the remote
* HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
* object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
*
* For unit testing applications that use `$http` service, see
* {@link ngMock.$httpBackend $httpBackend mock}.
*
* For a higher level of abstraction, please check out the {@link ngResource.$resource
* $resource} service.
*
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
* it is important to familiarize yourself with these APIs and the guarantees they provide.
*
*
* ## General usage
* The `$http` service is a function which takes a single argument — a configuration object —
* that is used to generate an HTTP request and returns a {@link ng.$q promise}
* with two $http specific methods: `success` and `error`.
*
* ```js
* // Simple GET request example :
* $http.get('/someUrl').
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // called asynchronously if an error occurs
* // or server returns response with an error status.
* });
* ```
*
* ```js
* // Simple POST request example (passing data) :
* $http.post('/someUrl', {msg:'hello word!'}).
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // called asynchronously if an error occurs
* // or server returns response with an error status.
* });
* ```
*
*
* Since the returned value of calling the $http function is a `promise`, you can also use
* the `then` method to register callbacks, and these callbacks will receive a single argument –
* an object representing the response. See the API signature and type info below for more
* details.
*
* A response status code between 200 and 299 is considered a success status and
* will result in the success callback being called. Note that if the response is a redirect,
* XMLHttpRequest will transparently follow it, meaning that the error callback will not be
* called for such responses.
*
* ## Writing Unit Tests that use $http
* When unit testing (using {@link ngMock ngMock}), it is necessary to call
* {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
* request using trained responses.
*
* ```
* $httpBackend.expectGET(...);
* $http.get(...);
* $httpBackend.flush();
* ```
*
* ## Shortcut methods
*
* Shortcut methods are also available. All shortcut methods require passing in the URL, and
* request data must be passed in for POST/PUT requests.
*
* ```js
* $http.get('/someUrl').success(successCallback);
* $http.post('/someUrl', data).success(successCallback);
* ```
*
* Complete list of shortcut methods:
*
* - {@link ng.$http#get $http.get}
* - {@link ng.$http#head $http.head}
* - {@link ng.$http#post $http.post}
* - {@link ng.$http#put $http.put}
* - {@link ng.$http#delete $http.delete}
* - {@link ng.$http#jsonp $http.jsonp}
* - {@link ng.$http#patch $http.patch}
*
*
* ## Setting HTTP Headers
*
* The $http service will automatically add certain HTTP headers to all requests. These defaults
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
* object, which currently contains this default configuration:
*
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
* - `Accept: application/json, text/plain, * / *`
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
* - `Content-Type: application/json`
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
* - `Content-Type: application/json`
*
* To add or overwrite these defaults, simply add or remove a property from these configuration
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
* with the lowercased HTTP method name as the key, e.g.
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
*
* The defaults can also be set at runtime via the `$http.defaults` object in the same
* fashion. For example:
*
* ```
* module.run(function($http) {
* $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
* });
* ```
*
* In addition, you can supply a `headers` property in the config object passed when
* calling `$http(config)`, which overrides the defaults without changing them globally.
*
* To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
* Use the `headers` property, setting the desired header to `undefined`. For example:
*
* ```js
* var req = {
* method: 'POST',
* url: 'http://example.com',
* headers: {
* 'Content-Type': undefined
* },
* data: { test: 'test' },
* }
*
* $http(req).success(function(){...}).error(function(){...});
* ```
*
* ## Transforming Requests and Responses
*
* Both requests and responses can be transformed using transformation functions: `transformRequest`
* and `transformResponse`. These properties can be a single function that returns
* the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
* which allows you to `push` or `unshift` a new transformation function into the transformation chain.
*
* ### Default Transformations
*
* The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
* `defaults.transformResponse` properties. If a request does not provide its own transformations
* then these will be applied.
*
* You can augment or replace the default transformations by modifying these properties by adding to or
* replacing the array.
*
* Angular provides the following default transformations:
*
* Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
*
* - If the `data` property of the request configuration object contains an object, serialize it
* into JSON format.
*
* Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
*
* - If XSRF prefix is detected, strip it (see Security Considerations section below).
* - If JSON response is detected, deserialize it using a JSON parser.
*
*
* ### Overriding the Default Transformations Per Request
*
* If you wish override the request/response transformations only for a single request then provide
* `transformRequest` and/or `transformResponse` properties on the configuration object passed
* into `$http`.
*
* Note that if you provide these properties on the config object the default transformations will be
* overwritten. If you wish to augment the default transformations then you must include them in your
* local transformation array.
*
* The following code demonstrates adding a new response transformation to be run after the default response
* transformations have been run.
*
* ```js
* function appendTransform(defaults, transform) {
*
* // We can't guarantee that the default transformation is an array
* defaults = angular.isArray(defaults) ? defaults : [defaults];
*
* // Append the new transformation to the defaults
* return defaults.concat(transform);
* }
*
* $http({
* url: '...',
* method: 'GET',
* transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
* return doTransform(value);
* })
* });
* ```
*
*
* ## Caching
*
* To enable caching, set the request configuration `cache` property to `true` (to use default
* cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
* When the cache is enabled, `$http` stores the response from the server in the specified
* cache. The next time the same request is made, the response is served from the cache without
* sending a request to the server.
*
* Note that even if the response is served from cache, delivery of the data is asynchronous in
* the same way that real requests are.
*
* If there are multiple GET requests for the same URL that should be cached using the same
* cache, but the cache is not populated yet, only one request to the server will be made and
* the remaining requests will be fulfilled using the response from the first request.
*
* You can change the default cache to a new object (built with
* {@link ng.$cacheFactory `$cacheFactory`}) by updating the
* {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set
* their `cache` property to `true` will now use this cache object.
*
* If you set the default cache to `false` then only requests that specify their own custom
* cache object will be cached.
*
* ## Interceptors
*
* Before you start creating interceptors, be sure to understand the
* {@link ng.$q $q and deferred/promise APIs}.
*
* For purposes of global error handling, authentication, or any kind of synchronous or
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
* able to intercept requests before they are handed to the server and
* responses before they are handed over to the application code that
* initiated these requests. The interceptors leverage the {@link ng.$q
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
*
* The interceptors are service factories that are registered with the `$httpProvider` by
* adding them to the `$httpProvider.interceptors` array. The factory is called and
* injected with dependencies (if specified) and returns the interceptor.
*
* There are two kinds of interceptors (and two kinds of rejection interceptors):
*
* * `request`: interceptors get called with a http `config` object. The function is free to
* modify the `config` object or create a new one. The function needs to return the `config`
* object directly, or a promise containing the `config` or a new `config` object.
* * `requestError`: interceptor gets called when a previous interceptor threw an error or
* resolved with a rejection.
* * `response`: interceptors get called with http `response` object. The function is free to
* modify the `response` object or create a new one. The function needs to return the `response`
* object directly, or as a promise containing the `response` or a new `response` object.
* * `responseError`: interceptor gets called when a previous interceptor threw an error or
* resolved with a rejection.
*
*
* ```js
* // register the interceptor as a service
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
* return {
* // optional method
* 'request': function(config) {
* // do something on success
* return config;
* },
*
* // optional method
* 'requestError': function(rejection) {
* // do something on error
* if (canRecover(rejection)) {
* return responseOrNewPromise
* }
* return $q.reject(rejection);
* },
*
*
*
* // optional method
* 'response': function(response) {
* // do something on success
* return response;
* },
*
* // optional method
* 'responseError': function(rejection) {
* // do something on error
* if (canRecover(rejection)) {
* return responseOrNewPromise
* }
* return $q.reject(rejection);
* }
* };
* });
*
* $httpProvider.interceptors.push('myHttpInterceptor');
*
*
* // alternatively, register the interceptor via an anonymous factory
* $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
* return {
* 'request': function(config) {
* // same as above
* },
*
* 'response': function(response) {
* // same as above
* }
* };
* });
* ```
*
* ## Security Considerations
*
* When designing web applications, consider security threats from:
*
* - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
* - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
*
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
* pre-configured with strategies that address these issues, but for this to work backend server
* cooperation is required.
*
* ### JSON Vulnerability Protection
*
* A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
* allows third party website to turn your JSON resource URL into
* [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
* Angular will automatically strip the prefix before processing it as JSON.
*
* For example if your server needs to return:
* ```js
* ['one','two']
* ```
*
* which is vulnerable to attack, your server can return:
* ```js
* )]}',
* ['one','two']
* ```
*
* Angular will strip the prefix, before processing the JSON.
*
*
* ### Cross Site Request Forgery (XSRF) Protection
*
* [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
* an unauthorized site can gain your user's private data. Angular provides a mechanism
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
* (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
* JavaScript that runs on your domain could read the cookie, your server can be assured that
* the XHR came from JavaScript running on your domain. The header will not be set for
* cross-domain requests.
*
* To take advantage of this, your server needs to set a token in a JavaScript readable session
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
* that only JavaScript running on your domain could have sent the request. The token must be
* unique for each user and must be verifiable by the server (to prevent the JavaScript from
* making up its own tokens). We recommend that the token is a digest of your site's
* authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
* for added security.
*
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
* properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
* or the per-request config object.
*
*
* @param {object} config Object describing the request to be made and how it should be
* processed. The object has following properties:
*
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
* to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
* JSONified.
* - **data** – `{string|Object}` – Data to be sent as the request message data.
* - **headers** – `{Object}` – Map of strings or functions which return strings representing
* HTTP headers to send to the server. If the return value of a function is null, the
* header will not be sent.
* - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
* - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
* - **transformRequest** –
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* request body and headers and returns its transformed (typically serialized) version.
* See {@link ng.$http#overriding-the-default-transformations-per-request
* Overriding the Default Transformations}
* - **transformResponse** –
* `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
* transform function or an array of such functions. The transform function takes the http
* response body, headers and status and returns its transformed (typically deserialized) version.
* See {@link ng.$http#overriding-the-default-transformations-per-request
* Overriding the Default Transformations}
* - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
* GET request, otherwise if a cache instance built with
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
* caching.
* - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
* that should abort the request when resolved.
* - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
* XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
* for more information.
* - **responseType** - `{string}` - see
* [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
*
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
* standard `then` method and two http specific methods: `success` and `error`. The `then`
* method takes two arguments a success and an error callback which will be called with a
* response object. The `success` and `error` methods take a single argument - a function that
* will be called when the request succeeds or fails respectively. The arguments passed into
* these functions are destructured representation of the response object passed into the
* `then` method. The response object has these properties:
*
* - **data** – `{string|Object}` – The response body transformed with the transform
* functions.
* - **status** – `{number}` – HTTP status code of the response.
* - **headers** – `{function([headerName])}` – Header getter function.
* - **config** – `{Object}` – The configuration object that was used to generate the request.
* - **statusText** – `{string}` – HTTP status text of the response.
*
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
* requests. This is primarily meant to be used for debugging purposes.

* @ngdoc service

*
* @requires $parse

*
* @description
*
* Compiles a string with markup into an interpolation function. This service is used by the
* HTML {@link ng.$compile $compile} service for data binding. See
* {@link ng.$interpolateProvider $interpolateProvider} for configuring the
* interpolation markup.
*
*
* ```js
* var $interpolate = ...; // injected
* var exp = $interpolate('Hello {{name | uppercase}}!');
* expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!');
* ```
*
* `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
* `true`, the interpolation function will return `undefined` unless all embedded expressions
* evaluate to a value other than `undefined`.
*
* ```js
* var $interpolate = ...; // injected
* var context = {greeting: 'Hello', name: undefined };
*
* // default "forgiving" mode
* var exp = $interpolate('{{greeting}} {{name}}!');
* expect(exp(context)).toEqual('Hello !');
*
* // "allOrNothing" mode
* exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
* expect(exp(context)).toBeUndefined();
* context.name = 'Angular';
* expect(exp(context)).toEqual('Hello Angular!');
* ```
*
* `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
*
* ####Escaped Interpolation
* $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
* can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
* It will be rendered as a regular start/end marker, and will not be interpreted as an expression
* or binding.
*
* This enables web-servers to prevent script injection attacks and defacing attacks, to some
* degree, while also enabling code examples to work without relying on the
* {@link ng.directive:ngNonBindable ngNonBindable} directive.
*
* **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
* replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
* interpolation start/end markers with their escaped counterparts.**
*
* Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
* output when the $interpolate service processes the text. So, for HTML elements interpolated
* by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
* set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
* this is typically useful only when user-data is used in rendering a template from the server, or
* when otherwise untrusted data is used by a directive.
*
* <example>
* <file name="index.html">
* <div ng-init="username='A user'">
* <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
* </p>
* <p><strong>{{username}}</strong> attempts to inject code which will deface the
* application, but fails to accomplish their task, because the server has correctly
* escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
* characters.</p>
* <p>Instead, the result of the attempted script injection is visible, and can be removed
* from the database by an administrator.</p>
* </div>
* </file>
* </example>
*
* @param {string} text The text with markup to interpolate.
* @param {boolean=} mustHaveExpression if set to true then the interpolation string must have
* embedded expression in order to return an interpolation function. Strings with no
* embedded expression will return null for the interpolation function.
* @param {string=} trustedContext when provided, the returned function passes the interpolated
* result through {@link ng.$sce#getTrusted $sce.getTrusted(interpolatedResult,
* trustedContext)} before returning it. Refer to the {@link ng.$sce $sce} service that
* provides Strict Contextual Escaping for details.
* @param {boolean=} allOrNothing if `true`, then the returned function returns undefined
* unless all embedded expressions evaluate to a value other than `undefined`.
* @returns {function(context)} an interpolation function which is used to compute the
* interpolated string. The function has these parameters:

/**
* @ngdoc service
* @name $interval
*
* @description
* Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
* milliseconds.
*
* The return value of registering an interval function is a promise. This promise will be
* notified upon each tick of the interval, and will be resolved after `count` iterations, or
* run indefinitely if `count` is not defined. The value of the notification will be the
* number of iterations that have run.
* To cancel an interval, call `$interval.cancel(promise)`.
*
* In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
* move forward by `millis` milliseconds and trigger any functions scheduled to run in that
* time.
*
* <div class="alert alert-warning">
* **Note**: Intervals created by this service must be explicitly destroyed when you are finished
* with them. In particular they are not automatically destroyed when a controller's scope or a
* directive's element are destroyed.
* You should take this into consideration and make sure to always cancel the interval at the
* appropriate moment. See the example below for more details on how and when to do this.
* </div>
*
* @param {function()} fn A function that should be called repeatedly.
* @param {number} delay Number of milliseconds between each function call.
* @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
* indefinitely.
* @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
* will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
* @returns {promise} A promise which will be notified on each iteration.

// Sandboxing Angular Expressions
// ------------------------------
// Angular expressions are generally considered safe because these expressions only have direct
// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
// obtaining a reference to native JS functions such as the Function constructor.
//
// As an example, consider the following Angular expression:
//
// {}.toString.constructor('alert("evil JS code")')
//
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
// against the expression language, but not to prevent exploits that were enabled by exposing
// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
// practice and therefore we are not even trying to protect against interaction with an object
// explicitly exposed in this way.
//
// In general, it is not possible to access a Window object from an angular expression unless a
// window or some DOM object that has a reference to window is published onto a Scope.
// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
// native objects.

/**
* @ngdoc service
* @name $q
* @requires $rootScope
*
* @description
* A service that helps you run functions asynchronously, and use their return values (or exceptions)
* when they are done processing.
*
* This is an implementation of promises/deferred objects inspired by
* [Kris Kowal's Q](https://github.com/kriskowal/q).
*
* $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
* implementations, and the other which resembles ES6 promises to some degree.
*
* # $q constructor
*
* The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
* function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,
* see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
*
* While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are
* available yet.
*
* It can be used like so:
*
* ```js
* // for the purpose of this example let's assume that variables `$q` and `okToGreet`
* // are available in the current lexical scope (they could have been injected or passed in).
*
* function asyncGreet(name) {
* // perform some asynchronous operation, resolve or reject the promise when appropriate.
* return $q(function(resolve, reject) {
* setTimeout(function() {
* if (okToGreet(name)) {
* resolve('Hello, ' + name + '!');
* } else {
* reject('Greeting ' + name + ' is not allowed.');
* }
* }, 1000);
* });
* }
*
* var promise = asyncGreet('Robin Hood');
* promise.then(function(greeting) {
* alert('Success: ' + greeting);
* }, function(reason) {
* alert('Failed: ' + reason);
* });
* ```
*
* Note: progress/notify callbacks are not currently supported via the ES6-style interface.
*
* However, the more traditional CommonJS-style usage is still available, and documented below.
*
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
* interface for interacting with an object that represents the result of an action that is
* performed asynchronously, and may or may not be finished at any given point in time.
*
* From the perspective of dealing with error handling, deferred and promise APIs are to
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
*
* ```js
* // for the purpose of this example let's assume that variables `$q` and `okToGreet`
* // are available in the current lexical scope (they could have been injected or passed in).
*
* function asyncGreet(name) {
* var deferred = $q.defer();
*
* setTimeout(function() {
* deferred.notify('About to greet ' + name + '.');
*
* if (okToGreet(name)) {
* deferred.resolve('Hello, ' + name + '!');
* } else {
* deferred.reject('Greeting ' + name + ' is not allowed.');
* }
* }, 1000);
*
* return deferred.promise;
* }

*
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff
* comes in the way of guarantees that promise and deferred APIs make, see
* https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
*
* Additionally the promise api allows for composition that is very hard to do with the
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
* section on serial or parallel joining of promises.
*
* # The Deferred API
*
* A new instance of deferred is constructed by calling `$q.defer()`.
*
* The purpose of the deferred object is to expose the associated Promise instance as well as APIs
* that can be used for signaling the successful or unsuccessful completion, as well as the status
* of the task.
*
* **Methods**
*
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
* constructed via `$q.reject`, the promise will be rejected instead.
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
* resolving it with a rejection constructed via `$q.reject`.
* - `notify(value)` - provides updates on the status of the promise's execution. This may be called
* multiple times before the promise is either resolved or rejected.
*
* **Properties**
*
* - promise – `{Promise}` – promise object associated with this deferred.
*
*
* # The Promise API
*
* A new promise instance is created when a deferred instance is created and can be retrieved by
* calling `deferred.promise`.
*
* The purpose of the promise object is to allow for interested parties to get access to the result
* of the deferred task when it completes.
*
* **Methods**
*
* - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
* will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
* as soon as the result is available. The callbacks are called with a single argument: the result
* or rejection reason. Additionally, the notify callback may be called zero or more times to
* provide a progress indication, before the promise is resolved or rejected.
*
* This method *returns a new promise* which is resolved or rejected via the return value of the
* `successCallback`, `errorCallback`. It also notifies via the return value of the
* `notifyCallback` method. The promise cannot be resolved or rejected from the notifyCallback
* method.
*
* - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
*
* - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
* but to do so without modifying the final value. This is useful to release resources or do some
* clean-up that needs to be done whether the promise was rejected or resolved. See the [full
* specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
* more information.
*
* # Chaining promises
*
* Because calling the `then` method of a promise returns a new derived promise, it is easily
* possible to create a chain of promises:
*
* ```js
* promiseB = promiseA.then(function(result) {
* return result + 1;
* });
*
* // promiseB will be resolved immediately after promiseA is resolved and its value
* // will be the result of promiseA incremented by 1
* ```
*
* It is possible to create chains of any length and since a promise can be resolved with another
* promise (which will defer its resolution further), it is possible to pause/defer resolution of
* the promises at any point in the chain. This makes it possible to implement powerful APIs like
* $http's response interceptors.
*
*
* # Differences between Kris Kowal's Q and $q
*
* There are two main differences:
*
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
* mechanism in angular, which means faster propagation of resolution or rejection into your
* models and avoiding unnecessary browser repaints, which would result in flickering UI.
* - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
* all the important functionality needed for common async tasks.
*
* # Testing
*
* ```js
* it('should simulate promise', inject(function($q, $rootScope) {
* var deferred = $q.defer();
* var promise = deferred.promise;
* var resolvedValue;
*
* promise.then(function(value) { resolvedValue = value; });
* expect(resolvedValue).toBeUndefined();
*
* // Simulate resolving of promise
* deferred.resolve(123);
* // Note that the 'then' function does not get called synchronously.
* // This is because we want the promise API to always be async, whether or not
* // it got called synchronously or asynchronously.
* expect(resolvedValue).toBeUndefined();
*
* // Propagate promise resolution to 'then' functions using $apply().
* $rootScope.$apply();
* expect(resolvedValue).toEqual(123);
* }));
* ```
*
* @param {function(function, function)} resolver Function which is responsible for resolving or
* rejecting the newly created promise. The first parameter is a function which resolves the
* promise, the second parameter is a function which rejects the promise.
*
* @returns {Promise} The newly created promise.

* DESIGN NOTES
*
* The design decisions behind the scope are heavily favored for speed and memory consumption.
*
* The typical use of scope is to watch the expressions, which most of the time return the same
* value as last time so we optimize the operation.
*
* Closures construction is expensive in terms of speed as well as memory:
* - No closures, instead use prototypical inheritance for API
* - Internal state needs to be stored on scope directly, which means that private state is
* exposed as $$____ properties
*
* Loop operations are optimized by using while(count--) { ... }
* - this means that in order to keep the same order of execution as addition we have to add
* items to the array at the beginning (unshift) instead of at the end (push)
*
* Child scopes are created and removed often
* - Using an array would be slow since inserts in middle are expensive so we use linked list
*
* There are few watches then a lot of observers. This is why you don't want the observer to be
* implemented in the same way as watch. Watch requires return of initialization function which
* are expensive to construct.

/**
* @ngdoc method
* @name $rootScope.Scope#$watch
* @kind function
*
* @description
* Registers a `listener` callback to be executed whenever the `watchExpression` changes.
*
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
* $digest()} and should return the value that will be watched. (Since
* {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the
* `watchExpression` can execute multiple times per
* {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
* - The `listener` is called only when the value from the current `watchExpression` and the
* previous call to `watchExpression` are not equal (with the exception of the initial run,
* see below). Inequality is determined according to reference inequality,
* [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
* via the `!==` Javascript operator, unless `objectEquality == true`
* (see next point)
* - When `objectEquality == true`, inequality of the `watchExpression` is determined
* according to the {@link angular.equals} function. To save the value of the object for
* later comparison, the {@link angular.copy} function is used. This therefore means that
* watching complex objects will have adverse memory and performance implications.
* - The watch `listener` may change the model, which may trigger other `listener`s to fire.
* This is achieved by rerunning the watchers until no changes are detected. The rerun
* iteration limit is 10 to prevent an infinite loop deadlock.
*
*
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
* you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
* can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a
* change is detected, be prepared for multiple calls to your listener.)
*
* After a watcher is registered with the scope, the `listener` fn is called asynchronously
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
* watcher. In rare cases, this is undesirable because the listener is called when the result
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
* listener was called due to initialization.
*
*
*

expect(scope.counter).toEqual(1);
scope.$digest();
// but now it will not be called unless the value changes
expect(scope.counter).toEqual(1);
scope.name = 'adam';
scope.$digest();
expect(scope.counter).toEqual(2);
// Using a function as a watchExpression

* @ngdoc method

* @kind function
*
* @description
* Shallow watches the properties of an object and fires whenever any of the properties change
* (for arrays, this implies watching the array items; for object maps, this implies watching
* the properties). If a change is detected, the `listener` callback is fired.
*
* - The `obj` collection is observed via standard $watch operation and is examined on every
* call to $digest() to see if any items have been added, removed, or moved.
* - The `listener` is called whenever anything within the `obj` has changed. Examples include
* adding, removing, and moving items belonging to an object or array.
*
*
* # Example
* ```js
$scope.names = ['igor', 'matias', 'misko', 'james'];
$scope.dataCount = 4;
$scope.$watchCollection('names', function(newNames, oldNames) {
$scope.dataCount = newNames.length;
});
expect($scope.dataCount).toEqual(4);
$scope.$digest();
//still at 4 ... no changes
expect($scope.dataCount).toEqual(4);
$scope.names.pop();
$scope.$digest();
//now there's been a change
expect($scope.dataCount).toEqual(3);
* ```
*
*
* @param {string|function(scope)} obj Evaluated as {@link guide/expression expression}. The
* expression value should evaluate to an object or an array which is observed on each
* {@link ng.$rootScope.Scope#$digest $digest} cycle. Any shallow change within the
* collection will trigger a call to the `listener`.
*
* @param {function(newCollection, oldCollection, scope)} listener a callback function called
* when a change is detected.
* - The `newCollection` object is the newly modified data obtained from the `obj` expression
* - The `oldCollection` object is a copy of the former collection data.
* Due to performance considerations, the`oldCollection` value is computed only if the
* `listener` function declares two or more arguments.
* - The `scope` argument refers to the current scope.
*
* @returns {function()} Returns a de-registration function for this listener. When the
* de-registration function is executed, the internal watch operation is terminated.

/**
* @ngdoc method
* @name $rootScope.Scope#$digest
* @kind function
*
* @description
* Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
* its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
* the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
* until no more listeners are firing. This means that it is possible to get into an infinite
* loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
* iterations exceeds 10.
*
* Usually, you don't call `$digest()` directly in
* {@link ng.directive:ngController controllers} or in
* {@link ng.$compileProvider#directive directives}.
* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
* a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
*
* If you want to be notified whenever `$digest()` is called,
* you can register a `watchExpression` function with
* {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
*
* In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
*
* # Example
* ```js
var scope = ...;
scope.name = 'misko';
scope.counter = 0;
expect(scope.counter).toEqual(0);
scope.$watch('name', function(newValue, oldValue) {
scope.counter = scope.counter + 1;
});
expect(scope.counter).toEqual(0);
scope.$digest();
// the listener is always called during the first $digest loop after it was registered
expect(scope.counter).toEqual(1);
scope.$digest();
// but now it will not be called unless the value changes
expect(scope.counter).toEqual(1);
scope.name = 'adam';
scope.$digest();
expect(scope.counter).toEqual(2);

*
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
*
* The default instance of `$sceDelegate` should work out of the box with little pain. While you

* @description
*
* `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
*
* # Strict Contextual Escaping
*
* Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
* contexts to result in a value that is marked as safe to use for that context. One example of
* such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer
* to these contexts as privileged or SCE contexts.
*
* As of version 1.2, Angular ships with SCE enabled by default.
*
* Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow
* one to execute arbitrary javascript by the use of the expression() syntax. Refer
* <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
* You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
* to the top of your HTML document.
*
* SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
* security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
*
* Here's an example of a binding in a privileged context:
*
* ```
* <input ng-model="userHtml">
* <div ng-bind-html="userHtml"></div>
* ```
*
* Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
* disabled, this application allows the user to render arbitrary HTML into the DIV.
* In a more realistic example, one may be rendering user comments, blog articles, etc. via
* bindings. (HTML is just one example of a context where rendering user controlled input creates
* security vulnerabilities.)
*
* For the case of HTML, you might use a library, either on the client side, or on the server side,
* to sanitize unsafe HTML before binding to the value and rendering it in the document.
*
* How would you ensure that every place that used these types of bindings was bound to a value that
* was sanitized by your library (or returned as safe for rendering by your server?) How can you
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
* properties/fields and forgot to update the binding to the sanitized value?
*
* To be secure by default, you want to ensure that any such bindings are disallowed unless you can
* determine that something explicitly says it's safe to use a value for binding in that
* context. You can then audit your code (a simple grep would do) to ensure that this is only done
* for those values that you can easily tell are safe - because they were received from your server,
* sanitized by your library, etc. You can organize your codebase to help with this - perhaps
* allowing only the files in a specific directory to do this. Ensuring that the internal API
* exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
*
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
* (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
* obtain values that will be accepted by SCE / privileged contexts.
*
*
* ## How does it work?
*
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
* $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
* ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
* {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
*
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
* ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
* simplified):
*
* ```
* var ngBindHtmlDirective = ['$sce', function($sce) {
* return function(scope, element, attr) {
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
* element.html(value || '');
* });
* };
* }];
* ```
*
* ## Impact on loading templates
*
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
* `templateUrl`'s specified by {@link guide/directive directives}.
*
* By default, Angular only loads templates from the same domain and protocol as the application
* document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
* protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
* them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
*
* *Please note*:
* The browser's
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
* policy apply in addition to this and may further restrict whether the template is successfully
* loaded. This means that without the right CORS policy, loading templates from a different domain
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some
* browsers.
*
* ## This feels like too much overhead
*
* It's important to remember that SCE only applies to interpolation expressions.
*
* If your expressions are constant literals, they're automatically trusted and you don't need to
* call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
* `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
*
* Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
* through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
*
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
* templates in `ng-include` from your application's domain without having to even know about SCE.
* It blocks loading templates from other domains or loading templates over http from an https
* served document. You can change these by setting your own custom {@link
* ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
* ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
*
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an
* application that's secure and can be audited to verify that with much more ease than bolting
* security onto an application later.
*
* <a name="contexts"></a>
* ## What trusted context types are supported?
*
* | Context | Notes |
* |---------------------|----------------|
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
* | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
* | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |
*
* ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
*
* Each element in these arrays must be one of the following:
*
* - **'self'**
* - The special **string**, `'self'`, can be used to match against all URLs of the **same
* domain** as the application document using the **same protocol**.
* - **String** (except the special value `'self'`)
* - The string is matched against the full *normalized / absolute URL* of the resource
* being tested (substring matches are not good enough.)
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
* match themselves.
* - `*`: matches zero or more occurrences of any character other than one of the following 6
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use
* in a whitelist.
* - `**`: matches zero or more occurrences of *any* character. As such, it's not
* not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g.
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
* not have been the intention.) Its usage at the very end of the path is ok. (e.g.
* http://foo.example.com/templates/**).
* - **RegExp** (*see caveat below*)
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should
* have good test coverage.). For instance, the use of `.` in the regex is correct only in a
* small number of cases. A `.` character in the regex used when matching the scheme or a
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It
* is highly recommended to use the string patterns and only fall back to regular expressions
* if they as a last resort.
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is
* matched against the **entire** *normalized / absolute URL* of the resource being tested
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
* present on the RegExp (such as multiline, global, ignoreCase) are ignored.
* - If you are generating your JavaScript from some other templating engine (not
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
* remember to escape your regular expression (and be aware that you might need more than
* one level of escaping depending on your templating engine and the way you interpolated
* the value.) Do make use of your platform's escaping mechanism as it might be good

* ## Can I disable SCE completely?
*
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
* for little coding overhead. It will be much harder to take an SCE disabled application and
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
* for cases where you have a lot of existing code that was written before SCE was introduced and
* you're migrating them a module at a time.
*
* That said, here's how you can completely disable SCE:
*
* ```
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
* // Completely disable SCE. For demonstration purposes only!
* // Do not use in new projects.
* $sceProvider.enabled(false);
* });
* ```

/* Design notes on the default implementation for SCE.
*
* The API contract for the SCE delegate
* -------------------------------------
* The SCE delegate object must provide the following 3 methods:
*
* - trustAs(contextEnum, value)
* This method is used to tell the SCE service that the provided value is OK to use in the
* contexts specified by contextEnum. It must return an object that will be accepted by
* getTrusted() for a compatible contextEnum and return this value.
*
* - valueOf(value)
* For values that were not produced by trustAs(), return them as is. For values that were
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if
* trustAs is wrapping the given values into some type, this operation unwraps it when given
* such a value.
*
* - getTrusted(contextEnum, value)
* This function should return the a value that is safe to use in the context specified by
* contextEnum or throw and exception otherwise.
*
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
* opaque or wrapped in some holder object. That happens to be an implementation detail. For
* instance, an implementation could maintain a registry of all trusted objects by context. In
* such a case, trustAs() would return the same object that was passed in. getTrusted() would
* return the same object passed in if it was found in the registry under a compatible context or
* throw an exception otherwise. An implementation might only wrap values some of the time based
* on some criteria. getTrusted() might return a value and not throw an exception for special
* constants or objects even if not wrapped. All such implementations fulfill this contract.
*
*
* A note on the inheritance model for SCE contexts
* ------------------------------------------------
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
* is purely an implementation details.
*
* The contract is simply this:
*
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
* will also succeed.
*
* Inheritance happens to capture this in a natural way. In some future, we
* may not use inheritance anymore. That is OK because no code outside of
* sce.js and sceSpecs.js would need to be aware of this detail.

/**
*
* Implementation Notes for non-IE browsers
* ----------------------------------------
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
* results both in the normalizing and parsing of the URL. Normalizing means that a relative
* URL will be resolved into an absolute URL in the context of the application document.
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
* properties are all populated to reflect the normalized URL. This approach has wide
* compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
*
* Implementation Notes for IE
* ---------------------------
* IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
* browsers. However, the parsed components will not be set if the URL assigned did not specify
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
* work around that by performing the parsing in a 2nd step by taking a previously normalized
* URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
* properties such as protocol, hostname, port, etc.
*
* IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one
* uses the inner HTML approach to assign the URL as part of an HTML snippet -
* http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL.
* Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
* Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
* method and IE < 8 is unsupported.

* @ngdoc provider

* @description
*
* Filters are just functions which transform input to an output. However filters need to be
* Dependency Injected. To achieve this a filter definition consists of a factory function which is
* annotated with dependencies and is responsible for creating a filter function.
*
* ```js
* // Filter registration
* function MyModule($provide, $filterProvider) {
* // create a service to demonstrate injection (not always needed)
* $provide.value('greet', function(name){
* return 'Hello ' + name + '!';
* });
*
* // register a filter factory which uses the
* // greet service to demonstrate DI.
* $filterProvider.register('greet', function(greet){
* // return the filter function which uses the greet service
* // to generate salutation
* return function(text) {
* // filters need to be forgiving so check input validity
* return text && greet(text) || text;
* };
* });
* }
* ```
*
* The filter function is registered with the `$injector` under the filter name suffix with
* `Filter`.
*
* ```js
* it('should be the same instance', inject(
* function($filterProvider) {
* $filterProvider.register('reverse', function(){
* return ...;
* });
* },
* function($filter, reverseFilter) {
* expect($filter('reverse')).toBe(reverseFilter);

* @ngdoc filter

* @kind function
*
* @description
* Selects a subset of items from `array` and returns it as a new array.
*
* @param {Array} array The source array.
* @param {string|Object|function()} expression The predicate to be used for selecting items from
* `array`.
*
* Can be one of:
*
* - `string`: The string is used for matching against the contents of the `array`. All strings or
* objects with string properties in `array` that match this string will be returned. This also
* applies to nested object properties.
* The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
* which have property `name` containing "M" and property `phone` containing "1". A special
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any
* property of the object or its nested object properties. That's equivalent to the simple
* substring match with a `string` as described above. The predicate can be negated by prefixing
* the string with `!`.
* For example `{name: "!M"}` predicate will return an array of items which have property `name`
* not containing "M".
*
* Note that a named property will match properties on the same level only, while the special
* `$` property will match properties on the same level or deeper. E.g. an array item like
* `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
* **will** be matched by `{$: 'John'}`.
*
* - `function(value, index)`: A predicate function can be used to write arbitrary filters. The
* function is called for each element of `array`. The final result is an array of those
* elements that the predicate returned true for.
*
* @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
* determining if the expected value (from the filter expression) and actual value (from
* the object in the array) should be considered a match.
*
* Can be one of:
*
* - `function(actual, expected)`:
* The function will be given the object value and the predicate value to compare and
* should return true if both values should be considered equal.
*
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
* This is essentially strict comparison of expected and actual.
*
* - `false|undefined`: A short hand for a function which will look for a substring match in case
* insensitive way.

/**
* @ngdoc filter
* @name date
* @kind function
*
* @description
* Formats `date` to a string based on the requested `format`.
*
* `format` string can be composed of the following elements:
*
* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
* * `'MMMM'`: Month in year (January-December)
* * `'MMM'`: Month in year (Jan-Dec)
* * `'MM'`: Month in year, padded (01-12)
* * `'M'`: Month in year (1-12)
* * `'dd'`: Day in month, padded (01-31)
* * `'d'`: Day in month (1-31)
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
* * `'EEE'`: Day in Week, (Sun-Sat)
* * `'HH'`: Hour in day, padded (00-23)
* * `'H'`: Hour in day (0-23)
* * `'hh'`: Hour in AM/PM, padded (01-12)
* * `'h'`: Hour in AM/PM, (1-12)
* * `'mm'`: Minute in hour, padded (00-59)
* * `'m'`: Minute in hour (0-59)
* * `'ss'`: Second in minute, padded (00-59)
* * `'s'`: Second in minute (0-59)
* * `'sss'`: Millisecond in second, padded (000-999)
* * `'a'`: AM/PM marker
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
* * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
* * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
*
* `format` string can also be one of the following predefined
* {@link guide/i18n localizable formats}:
*
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
* (e.g. Sep 3, 2010 12:05:08 PM)
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
* * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
* (e.g. Friday, September 3, 2010)
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
*
* `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
* `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
* (e.g. `"h 'o''clock'"`).
*
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
* specified in the string input, the time is considered to be in the local timezone.
* @param {string=} format Formatting rules (see Description). If not specified,
* `mediumDate` is used.
* @param {string=} timezone Timezone to be used for formatting. Right now, only `'UTC'` is supported.
* If not specified, the timezone of the browser will be used.
* @returns {string} Formatted string or the input if input is not recognized as date/millis.

* @description
* Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
* for strings and numerically for numbers. Note: if you notice numbers are not being sorted
* correctly, make sure they are actually being saved as numbers and not strings.
*
* @param {Array} array The array to sort.
* @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be
* used by the comparator to determine the order of elements.
*
* Can be one of:
*
* - `function`: Getter function. The result of this function will be sorted using the
* `<`, `=`, `>` operator.
* - `string`: An Angular expression. The result of this expression is used to compare elements
* (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
* 3 first characters of a property called `name`). The result of a constant expression
* is interpreted as a property name to be used in comparisons (for example `"special name"`
* to sort object by the value of their `special name` property). An expression can be
* optionally prefixed with `+` or `-` to control ascending or descending sort order
* (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array
* element itself is used to compare where sorting.
* - `Array`: An array of function or string predicates. The first predicate in the array
* is used for sorting, but when two items are equivalent, the next predicate is used.
*
* If the predicate is missing or empty then it defaults to `'+'`.
*
* @param {boolean=} reverse Reverse the order of the array.

* @description
* Directive that instantiates
* {@link form.FormController FormController}.
*
* If the `name` attribute is specified, the form controller is published onto the current scope under
* this name.
*
* # Alias: {@link ng.directive:ngForm `ngForm`}
*
* In Angular forms can be nested. This means that the outer form is valid when all of the child
* forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
* Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
* `<form>` but can be nested. This allows you to have nested forms, which is very useful when
* using Angular validation directives in forms that are dynamically generated using the
* {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
* attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
* `ngForm` directive and nest these in an outer `form` element.
*
*
* # CSS classes
* - `ng-valid` is set if the form is valid.
* - `ng-invalid` is set if the form is invalid.
* - `ng-pristine` is set if the form is pristine.
* - `ng-dirty` is set if the form is dirty.
* - `ng-submitted` is set if the form was submitted.
*
* Keep in mind that ngAnimate can detect each of these classes when added and removed.
*
*
* # Submitting a form and preventing the default action
*
* Since the role of forms in client-side Angular applications is different than in classical
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full
* page reload that sends the data to the server. Instead some javascript logic should be triggered
* to handle the form submission in an application-specific way.
*
* For this reason, Angular prevents the default action (form submission to the server) unless the
* `<form>` element has an `action` attribute specified.
*
* You can use one of the following two ways to specify what javascript method should be called when
* a form is submitted:
*
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
* - {@link ng.directive:ngClick ngClick} directive on the first
* button or input field of type submit (input[type=submit])
*
* To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
* or {@link ng.directive:ngClick ngClick} directives.
* This is because of the following form submission rules in the HTML specification:
*
* - If a form has only one input field then hitting enter in this field triggers form submit
* (`ngSubmit`)
* - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
* doesn't trigger submit
* - if a form has one or more input fields and one or more buttons or input[type=submit] then
* hitting enter in any of the input fields will trigger the click handler on the *first* button or
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
*
* Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
* submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
* to have access to the updated model.
*
* ## Animation Hooks
*
* Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
* These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
* other validations that are performed within the form. Animations in ngForm are similar to how
* they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
* as JS animations.
*
* The following example shows a simple way to utilize CSS transitions to style a form element
* that has been rendered as invalid after it has been validated:
*
* <pre>
* //be sure to include ngAnimate as a module to hook into more
* //advanced animations
* .my-form {
* transition:0.5s linear all;
* background: white;
* }
* .my-form.ng-invalid {
* background: red;
* color:white;
* }
* </pre>
*
* @example
<example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
<file name="index.html">
<script>
angular.module('formExample', [])
.controller('FormController', ['$scope', function($scope) {

/**
* @ngdoc input
* @name input[text]
*
* @description
* Standard HTML text input with angular data binding, inherited by most of the `input` elements.
*
*
* @param {string} ngModel Assignable angular expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} required Adds `required` validation error key if the value is not entered.
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
* `required` when you want to data-bind to the `required` attribute.
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
* minlength.
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
* any length.
* @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
* that contains the regular expression body that will be converted to a regular expression
* as in the ngPattern directive.
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match
* a RegExp found by evaluating the Angular expression given in the attribute value.
* If the expression evaluates to a RegExp object then this is used directly.
* If the expression is a string then it will be converted to a RegExp after wrapping it in `^` and `$`
* characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
* @param {string=} ngChange Angular expression to be executed when input changes due to user
* interaction with the input element.
* @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
* This parameter is ignored for input[type=password] controls, which will never trim the
* input.
*

/**
* @ngdoc input
* @name input[date]
*
* @description
* Input with date validation and transformation. In browsers that do not yet support
* the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
* date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
* modern browsers do not yet support this input type, it is important to provide cues to users on the
* expected input format via a placeholder or label.
*
* The model must always be a Date object, otherwise Angular will throw an error.
* Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
*
* The timezone to be used to read/write the `Date` instance in the model can be defined using
* {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
*
* @param {string} ngModel Assignable angular expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
* valid ISO date string (yyyy-MM-dd).
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
* a valid ISO date string (yyyy-MM-dd).
* @param {string=} required Sets `required` validation error key if the value is not entered.
