/**

* @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#methods_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:
*
*
* 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, $transclude, otherInjectables) { ... },
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
* compile: function compile(tElement, tAttrs, transclude) {
* return {
* pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* post: function postLink(scope, iElement, iAttrs, controller) { ... }
* }
* // or
* // return function postLink( ... ) { ... }
* },
* // or
* // link: {
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... },
* // post: function postLink(scope, iElement, iAttrs, controller) { ... }
* // }
* // or
* // link: function postLink( ... ) { ... }
* };
* return directiveDefinitionObject;
* });
*
*
*
* **Note:** Any unspecified options will use the default value. You can see the default values below.
*
*
* Therefore the above can be simplified as:
*
*
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* link: function postLink(scope, iElement, iAttrs) { ... }
* };
* return directiveDefinitionObject;
* // or
* // return function postLink(scope, iElement, iAttrs) { ... }
* });
*
*
*
*
* ### Directive Definition Object
*
* The directive definition object provides instructions to the {@link api/ng.$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: ``
* * `A` - Attribute (default): `
`
* * `C` - Class: `
`
* * `M` - Comment: ``
*
*
* #### `template`
* replace the current element with the contents of the HTML. The replacement process
* migrates all of the attributes / classes from the old element to the new one. See the
* {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive
* Directives Guide} for an example.
*
* You can specify `template` as a string representing the template 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 template.
*
*
* #### `templateUrl`
* Same as `template` but the template is loaded from the specified URL. Because
* the template loading is asynchronous the compilation/linking is suspended until the template
* is loaded.
*
* 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
* api/ng.$sce#methods_getTrustedResourceUrl $sce.getTrustedResourceUrl}.
*
*
* #### `replace`
* specify where the template should be inserted. Defaults to `false`.
*
* * `true` - the template will replace the current element.
* * `false` - the template will replace the contents of the current element.
*
*
* #### `transclude`
* compile the content of the element and make it available to the directive.
* Typically used with {@link api/ng.directive:ngTransclude
* ngTransclude}. The advantage of transclusion is that the linking function receives a
* transclusion function which is pre-bound to the correct scope. In a typical setup the widget
* creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
* scope. This makes it possible for the widget to have private state, and the transclusion to
* be bound to the parent (pre-`isolate`) scope.
*
* * `true` - transclude the content of the directive.
* * `'element'` - transclude the whole element including any directives defined at lower priority.
*
*
* #### `compile`
*
*
* 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. Examples that require compile functions are
* directives that transform template DOM, such as {@link
* api/ng.directive:ngRepeat ngRepeat}, or load the contents
* asynchronously, such as {@link api/ngRoute.directive:ngView ngView}. 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)`
*
*
* **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.
*
*
*
* **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.
*
* 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.
*
*
* 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 api/ng.$rootScope.Scope Scope} - The scope to be used by the
* directive for registering {@link api/ng.$rootScope.Scope#methods_$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.
* The scope can be overridden by an optional first argument. This is the same as the `$transclude`
* parameter of directive controllers.
* `function([scope], cloneLinkingFn)`.
*
*
* #### Pre-linking function
*
* Executed before the child elements are linked. Not safe to do DOM transformation since the
* compiler linking function will fail to locate the correct elements for linking.
*
* #### Post-linking function
*
* Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function.
*
*
* ### Attributes
*
* The {@link api/ng.$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 `$observe` to observe the value changes of attributes
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
* the only way to easily get the actual value because during the linking phase the interpolation
* hasn't been evaluated yet and so the value is at this time set to `undefined`.
*
*
* function linkingFn(scope, elm, attrs, ctrl) {
* // get the attribute value
* console.log(attrs.ngModel);
*
* // change the attribute
* attrs.$set('ngModel', 'new value');
*
* // observe changes to interpolated attribute
* attrs.$observe('ngModel', function(value) {
* console.log('ngModel has changed value to ' + value);
* });
* }
*
*
* Below is an example using `$compileProvider`.
*
*
* **Note**: Typically directives are registered with `module.directive`. The example below is
* to illustrate how `$compile` works.
*
*
it('should auto compile', function() {
expect(element('div[compile]').text()).toBe('Hello Angular');
input('html').enter('{{name}}!');
expect(element('div[compile]').text()).toBe('Angular!');
});
*
*
* @param {string|DOMElement} element Element or HTML string to compile into a template function.
* @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
* @param {number} maxPriority only apply directives lower then given priority (Only effects the
* root element(s), not their children)
* @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link ng.$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.
*
* 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:
*
* 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.
