*
* This object provides a utility for producing rich Error messages within
* Angular. It can be called as follows:
*
* var exampleMinErr = minErr('example');
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
*
* The above creates an instance of minErr in the example namespace. The
* resulting error will have a namespaced error code of example.one. The
* resulting error will replace {0} with the value of foo, and {1} with the
* value of bar. The object is not restricted in the number of arguments it can
* take.
*
* If fewer arguments are specified than necessary for interpolation, the extra
* interpolation markers will be preserved in the final string.
*
* Since data will be parsed statically during a build step, some restrictions
* are applied with respect to how minErr instances are created and called.
* Instances should have names of the form namespaceMinErr for a minErr created
* using minErr('namespace') . Error codes, namespaces and template strings
* should all be static strings, not variables or general expressions.
*
* @param {string} module The namespace to use for the new minErr instance.

* @ngdoc directive
* @name ngApp
* @module ng
*
* @element ANY
* @param {angular.Module} ngApp an optional application
* {@link angular.module module} name to load.
*
* @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 `` or `` 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 and
* 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.
*
I can add: {{a}} + {{b}} = {{ a+b }}

* # Module
*
* A module is a collection of services, directives, 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

* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
*
* 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.
*
* To use jQuery, simply load it before `DOMContentLoaded` event fired.
*
* **Note:** all element references in Angular are always wrapped with jQuery or
* jqLite; they are never raw DOM references.
*
* ## 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/)
* - [`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/)
* - [`data()`](http://api.jquery.com/data/)
* - [`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.
* - `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.
* - `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

* @function
*
* @description
* Creates an injector function that can be used for retrieving services as well as for
* dependency injection (see {@link guide/di dependency injection}).
*
* @param {Array.} modules A list of module functions or their aliases. See
* {@link angular.module}. The `ng` module must be explicitly added.
* @returns {function()} Injector function. 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 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 = $('{{content.label}}');
* $(document.body).append($div);
*
* angular.element(document).injector().invoke(function($compile) {
* var scope = angular.element($div).scope();
* $compile($div)(scope);
* });

/**
* @ngdoc service
* @name $injector
* @function
*
* @description
*
* `$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
* $injector.invoke(['serviceA', function(serviceA){}]);
* ```
*
* ## Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition
* can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with
* minification, and obfuscation tools since these tools change the argument names.
*
* ## `$inject` Annotation
* By adding a `$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', '$route']);
* ```
*
* This method does not work with code minification / obfuscation. For this reason the following
* annotation strategies are supported.
*
* # The `$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.} fn Function for which dependent service names need to
* be retrieved as described above.
*
* @returns {Array.} The names of the services which the function requires.

/**
* @ngdoc object
* @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');

/**
* @ngdoc service
* @name $compile
* @function
*
* @description
* Compiles an HTML string or DOM into a template and produces a template function, which
* can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
*
* The compilation is a process of walking the DOM tree and matching DOM elements to
* {@link ng.$compileProvider#directive directives}.
*
*
* **Note:** This document is an in-depth reference of all directive options.
* For a gentle introduction to directives with examples of common use cases,
* see the {@link guide/directive directive guide}.
*
*
* ## Comprehensive Directive API
*
* There are many different options for a directive.
*
* The difference resides in the return value of the factory function.
* You can either return a "Directive Definition Object" (see below) that defines the directive properties,
* or just the `postLink` function (all other properties will have the default values).
*
*
* **Best Practice:** It's recommended to use the "directive definition object" form.
*
*
* Here's an example directive declared with a Directive Definition Object:
*
* ```js
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* priority: 0,
* template: '', // or // function(tElement, tAttrs) { ... },
* // or
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
* replace: false,
* transclude: false,
* restrict: 'A',
* scope: false,
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
* controllerAs: 'stringAlias',
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
* compile: function compile(tElement, tAttrs, transclude) {
* return {
* pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* post: function postLink(scope, iElement, iAttrs, controller) { ... }
* }
* // or
* // return function postLink( ... ) { ... }
* },
* // or
* // link: {
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* // post: function postLink(scope, iElement, iAttrs, controller) { ... }
* // }
* // or
* // link: function postLink( ... ) { ... }
* };
* return directiveDefinitionObject;
* });
* ```
*
*
* **Note:** Any unspecified options will use the default value. You can see the default values below.
*
*
* Therefore the above can be simplified as:
*
* ```js
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* link: function postLink(scope, iElement, iAttrs) { ... }
* };
* return directiveDefinitionObject;
* // or
* // return function postLink(scope, iElement, iAttrs) { ... }
* });
* ```
*
*
*
* ### Directive Definition Object
*
* The directive definition object provides instructions to the {@link ng.$compile
* compiler}. The attributes are:
*
* #### `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).
*
* #### `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 `` 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 `` 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.
*
* * `&` 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 `` 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 and 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})`.
*
*
*
* #### `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.
* The scope can be overridden by an optional first argument.
* `function([scope], cloneLinkingFn)`.
*
*
* #### `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's parents. Throw an error 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 default (attributes only) is used.
*
* * `E` - Element name: `
it('should auto compile', function() {
var textarea = $('textarea');
var output = $('div[compile]');
// The initial state reads 'Hello Angular'.
expect(output.getText()).toBe('Hello Angular');
textarea.clear();
textarea.sendKeys('{{name}}!');
expect(output.getText()).toBe('Angular!');
});
*
*
* @param {string|DOMElement} element Element or HTML string to compile into a template function.
* @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives.
* @param {number} maxPriority only apply directives lower than given priority (Only effects the
* root element(s), not their children)
* @returns {function(scope, cloneAttachFn=)} a link function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link ng.$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:
`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.
*
* 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('{{total}}
')(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('{{total}}
'),
* 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`
* ```
*
*
* For information on how the compiler works, see the
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

/**
* @ngdoc service
* @kind function
* @name $http
* @requires ng.$httpBackend
* @requires $cacheFactory
* @requires $rootScope
* @requires $q
* @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
* $http({method: 'GET', url: '/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.
* });
* ```
*
* 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}
*
*
* # 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.
*
*
* # Transforming Requests and Responses
*
* Both requests and responses can be transformed using transform functions. By default, Angular
* applies these transformations:
*
* Request transformations:
*
* - If the `data` property of the request configuration object contains an object, serialize it
* into JSON format.
*
* Response transformations:
*
* - If XSRF prefix is detected, strip it (see Security Considerations section below).
* - If JSON response is detected, deserialize it using a JSON parser.
*
* To globally augment or override the default transforms, modify the
* `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse`
* properties. These properties are by default an array of transform functions, which allows you
* to `push` or `unshift` a new transformation function into the transformation chain. You can
* also decide to completely override any default transformations by assigning your
* transformation functions to these properties directly without the array wrapper. These defaults
* are again available on the $http factory at run-time, which may be useful if you have run-time
* services you wish to be involved in your transformations.
*
* Similarly, to locally override the request/response transforms, augment the
* `transformRequest` and/or `transformResponse` properties of the configuration object passed
* into `$http`.
*
*
* # 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#properties_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 http `config` object. The function is free to
* modify the `config` or create a new one. The function needs to return the `config`
* directly or as a promise.
* * `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` or create a new one. The function needs to return the `response`
* directly or as a promise.
* * `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 || $q.when(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 || $q.when(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
* }
* };
* });
* ```
*
* # Response interceptors (DEPRECATED)
*
* Before you start creating interceptors, be sure to understand the
* {@link ng.$q $q and deferred/promise APIs}.
*
* For purposes of global error handling, authentication or any kind of synchronous or
* asynchronous preprocessing of received responses, it is desirable to be able to intercept
* responses for http requests before they are handed over to the application code that
* initiated these requests. The response interceptors leverage the {@link ng.$q
* promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
*
* The interceptors are service factories that are registered with the $httpProvider by
* adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
* injected with dependencies (if specified) and returns the interceptor — a function that
* takes a {@link ng.$q promise} and returns the original or a new promise.
*
* ```js
* // register the interceptor as a service
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
* return function(promise) {
* return promise.then(function(response) {
* // do something on success
* return response;
* }, function(response) {
* // do something on error
* if (canRecover(response)) {
* return responseOrNewPromise
* }
* return $q.reject(response);
* });
* }
* });
*
* $httpProvider.responseInterceptors.push('myHttpInterceptor');
*
*
* // register the interceptor via an anonymous factory
* $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
* return function(promise) {
* // 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))
* 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.}` – 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.}` –
* 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.
* - **transformResponse** –
* `{function(data, headersGetter)|Array.}` –
* transform function or an array of such functions. The transform function takes the http
* response body and headers and returns its transformed (typically deserialized) version.
* - **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 to set the `withCredentials` flag on the
* XHR object. See [requests with credentials]https://developer.mozilla.org/en/http_access_control#section_5
* for more information.
* - **responseType** - `{string}` - see
* [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
*
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
* standard `then` method and two http specific methods: `success` and `error`. The `then`
* method takes two arguments a success and an error callback which will be called with a
* response object. The `success` and `error` methods take a single argument - a function that
* will be called when the request succeeds or fails respectively. The arguments passed into
* these functions are destructured representation of the response object passed into the
* `then` method. The response object has these properties:
*
* - **data** – `{string|Object}` – The response body transformed with the transform
* functions.
* - **status** – `{number}` – HTTP status code of the response.
* - **headers** – `{function([headerName])}` – Header getter function.
* - **config** – `{Object}` – The configuration object that was used to generate the request.
* - **statusText** – `{string}` – HTTP status text of the response.
*
* @property {Array.
*
* @param {function()} fn A function that should be called repeatedly.
* @param {number} delay Number of milliseconds between each function call.
* @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
* indefinitely.
* @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
* will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
* @returns {promise} A promise which will be notified on each iteration.
*
* @example
*
*
*
*

*
* Blood 1 : {{blood_1}}

// 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"))
//
// We want to prevent this type of access. For the sake of performance, during the lexing phase we
// disallow any "dotted" access to any member named "constructor".
//
// For reflective calls (a[b]) we check that the value of the lookup is not the Function constructor
// while evaluating the expression, which is a stronger but more expensive test. Since reflective
// calls are expensive anyway, this is not such a big deal compared to static dereferencing.
//
// 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.
//
// A developer could foil the name check by aliasing the Function constructor under a different
// name on the scope.
//
// 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.

*
* **This feature is deprecated, see deprecation notes below for more info**
*
* If set to true (default is false), $parse will unwrap promises automatically when a promise is
* found at any part of the expression. In other words, if set to true, the expression will always
* result in a non-promise value.
*
* While the promise is unresolved, it's treated as undefined, but once resolved and fulfilled,
* the fulfillment value is used in place of the promise while evaluating the expression.
*
* **Deprecation notice**
*
* This is a feature that didn't prove to be wildly useful or popular, primarily because of the
* dichotomy between data access in templates (accessed as raw values) and controller code
* (accessed as promises).
*
* In most code we ended up resolving promises manually in controllers anyway and thus unifying
* the model access there.
*
* Other downsides of automatic promise unwrapping:
*
* - when building components it's often desirable to receive the raw promises
* - adds complexity and slows down expression evaluation
* - makes expression code pre-generation unattractive due to the amount of code that needs to be
* generated
* - makes IDE auto-completion and tool support hard
*
* **Warning Logs**
*
* If the unwrapping is enabled, Angular will log a warning about each expression that unwraps a
* promise (to reduce the noise, each expression is logged only once). To disable this logging use
* `$parseProvider.logPromiseWarnings(false)` api.

/**
* @ngdoc service
* @name $q
* @requires $rootScope
*
* @description
* A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
*
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
* interface for interacting with an object that represents the result of an action that is
* performed asynchronously, and may or may not be finished at any given point in time.
*
* From the perspective of dealing with error handling, deferred and promise APIs are to
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
*
* ```js
* // for the purpose of this example let's assume that variables `$q`, `scope` 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() {
* // since this fn executes async in a future turn of the event loop, we need to wrap
* // our code into an $apply call so that the model changes are properly observed.
* scope.$apply(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;
* }
*
* var promise = asyncGreet('Robin Hood');
* promise.then(function(greeting) {
* alert('Success: ' + greeting);
* }, function(reason) {
* alert('Failed: ' + reason);
* }, function(update) {
* alert('Got notification: ' + update);
* });
* ```
*
* 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 can not be resolved or rejected from the notifyCallback
* method.
*
* - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
*
* - `finally(callback)` – 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.
*
* Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as
* property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to
* make your code IE8 and Android 2.x compatible.
*
* # 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);
* }));
* ```

* 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 (shift) 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.

* - 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.
*
* The example below contains an illustration of using a function as your $watch listener
*
*
* # Example
* ```js
// let's assume that scope was dependency injected as the $rootScope
var scope = $rootScope;
scope.name = 'misko';
scope.counter = 0;
expect(scope.counter).toEqual(0);
scope.$watch('name', function(newValue, oldValue) {
scope.counter = scope.counter + 1;
});
expect(scope.counter).toEqual(0);
scope.$digest();
// no variable change
expect(scope.counter).toEqual(0);
scope.name = 'adam';
scope.$digest();
expect(scope.counter).toEqual(1);
// Using a listener function
var food;
scope.foodCounter = 0;
expect(scope.foodCounter).toEqual(0);
scope.$watch(
// This is the listener function
function() { return food; },
// This is the change handler
function(newValue, oldValue) {
if ( newValue !== oldValue ) {
// Only increment the counter if the value changed
scope.foodCounter = scope.foodCounter + 1;
}
}
);
// No digest has been run so the counter will be zero
expect(scope.foodCounter).toEqual(0);
// Run the digest but since food has not changed count will still be zero
scope.$digest();
expect(scope.foodCounter).toEqual(0);
// Update food and run digest. Now the counter will increment
food = 'cheeseburger';
scope.$digest();
expect(scope.foodCounter).toEqual(1);
* ```
*
*
*
* @param {(function()|string)} watchExpression Expression that is evaluated on each
* {@link ng.$rootScope.Scope#$digest $digest} cycle. A change in the return value triggers
* a call to the `listener`.

* @ngdoc method
* @name $rootScope.Scope#$watchCollection
* @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.

*
* @description

* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within

*
* If you want to be notified whenever `$digest()` is called,

*
* The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
* $sceDelegate} service. This allows one to get/set the whitelists and blacklists used to ensure
* that the URLs used for sourcing Angular templates are safe. Refer {@link
* ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist} and
* {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
*
* For the general details about this service in Angular, read the main page for {@link ng.$sce
* Strict Contextual Escaping (SCE)}.
*
* **Example**: Consider the following case.
*
* - your app is hosted at url `http://myapp.example.com/`
* - but some of your templates are hosted on other domains you control such as
* `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
* - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
*
* Here is what a secure configuration for this scenario might look like:
*
*
* angular.module('myApp', []).config(function($sceDelegateProvider) {
* $sceDelegateProvider.resourceUrlWhitelist([
* // Allow same origin resource loads.
* 'self',
* // Allow loading from our assets domain. Notice the difference between * and **.
* 'http://srv*.assets.example.com/**']);
*
* // The blacklist overrides the whitelist so the open redirect here is blocked.
* $sceDelegateProvider.resourceUrlBlacklist([
* 'http://myapp.example.com/clickThru**']);
* });
*

*
* @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), IE8 in quirks mode is not supported. In this mode, IE8 allows
* one to execute arbitrary javascript by the use of the expression() syntax. Refer
* to learn more about them.
* You can ensure your document is in standards mode and not quirks mode by adding ``
* 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:
*
*
*
*
*
*
* 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#parse $sce.parseAs} rather than `$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.$sce#trustAsResourceUrl wrap it} into a trusted value.
*
* *Please note*:
* The browser's
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
* policy apply in addition to this and may further restrict whether the template is successfully
* loaded. This means that without the right CORS policy, loading templates from a different domain
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some
* browsers.
*
* ## This feels like too much overhead for the developer?
*
* It's important to remember that SCE only applies to interpolation expressions.
*
* If your expressions are constant literals, they're automatically trusted and you don't need to
* call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
* ``) 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.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
*
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an
* application that's secure and can be audited to verify that with much more ease than bolting
* security onto an application later.
*
*
* ## What trusted context types are supported?
*
* | Context | Notes |
* |---------------------|----------------|
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. |
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
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}
*
* 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.) It's 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
* enough before coding your own. e.g. Ruby has
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
* Javascript lacks a similar built in function for escaping. Take a look at Google
* Closure library's [goog.string.regExpEscape(s)](
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
*
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.
*
* ## Show me an example using SCE.
*
* @example
User comments
By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
$sanitize is available. If $sanitize isn't available, this results in an error instead of an
exploit.
{{userComment.name}}:
var mySceApp = angular.module('mySceApp', ['ngSanitize']);
mySceApp.controller("myAppController", function myAppController($http, $templateCache, $sce) {
var self = this;
$http.get("test_data.json", {cache: $templateCache}).success(function(userComments) {
self.userComments = userComments;
});
self.explicitlyTrustedHtml = $sce.trustAsHtml(
'Hover over this text.');
});
[
{ "name": "Alice",
"htmlComment":
"Is anyone reading this?"
},
{ "name": "Bob",
"htmlComment": "Yes! Am I the only other one?"
}
]
describe('SCE doc demo', function() {
it('should sanitize untrusted values', function() {
expect(element(by.css('.htmlComment')).getInnerHtml())
.toBe('Is anyone reading this?');
});
it('should NOT sanitize explicitly trusted values', function() {
expect(element(by.id('explicitlyTrustedHtml')).getInnerHtml()).toBe(
'Hover over this text.');
});
});
*
*
*
* ## Can I disable SCE completely?
*
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
* for little coding overhead. It will be much harder to take an SCE disabled application and
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
* for cases where you have a lot of existing code that was written before SCE was introduced and
* you're migrating them a module at a time.
*
* That said, here's how you can completely disable SCE:
*
*
* angular.module('myAppWithSceDisabledmyApp', []).config(function($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.

*
* ```js
* // Filter registration
* function MyModule($provide, $filterProvider) {
* // create a service to demonstrate injection (not always needed)
* $provide.value('greet', function(name){

* $filterProvider.register('greet', function(greet){
* // return the filter function which uses the greet service
* // to generate salutation
* return function(text) {
* // filters need to be forgiving so check input validity
* return text && greet(text) || text;
* };
* });
* }
* ```
*
* The filter function is registered with the `$injector` under the filter name suffix with
* `Filter`.
*
* ```js
* it('should be the same instance', inject(
* function($filterProvider) {

* @ngdoc filter

* @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 evaluated as an expression and the resulting value is used for substring match against
* the contents of the `array`. All strings or objects with string properties in `array` that contain this string
* will be returned. 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. That's equivalent to the simple substring match with a `string`
* as described above.
*
* - `function(value)`: 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 the item should be included in filtered result.
*
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`.
* 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.
*

* 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' or ',sss'`: Millisecond in second, padded (000-999)
* * `'a'`: am/pm marker
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
*
* `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 quoted with single quotes (e.g.
* `"h 'in the morning'"`). In order to output single quote, use 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.
* @returns {string} Formatted string or the input if input is not recognized as date/millis.
