+ * @ngdoc directive
+ * @name ngBind
+ * @restrict AC
  *
  * @description
+ * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
+ * with the value of a given expression, and to update the text content when the value of that
+ * expression changes.
+ *
+ * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
+ * `{{ expression }}` which is similar but less verbose.
  *
- * `NgModelController` provides API for the `ng-model` directive. The controller contains
- * services for data-binding, validation, CSS updates, and value formatting and parsing. It
- * purposefully does not contain any logic which deals with DOM rendering or listening to
- * DOM events. Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding.
+ * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
+ * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
+ * element attribute, it makes the bindings invisible to the user while the page is loading.
  *
- * ## Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
+ * An alternative solution to this problem would be using the
+ * {@link ng.directive:ngCloak ngCloak} directive.
  *
- * Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.  This will not work on older browsers.
  *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to to provide unsafe content if it marks
- * that content using the `$sce` service.
+ * @element ANY
+ * @param {expression} ngBind {@link guide/expression Expression} to evaluate.
  *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;
-        background-color: white;
-        min-height: 20px;
-      }
+ * @example
+ * Enter a name in the Live Preview text box; the greeting below the text box changes instantly.

+ * @ngdoc directive
+ * @name ngClass
+ * @restrict AC
+ *
+ * @description
+ * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
+ * an expression that represents all classes to be added.
+ *
+ * The directive operates in three different ways, depending on which of three types the expression
+ * evaluates to:
+ *
+ * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
+ * names.
+ *
+ * 2. If the expression evaluates to an array, each element of the array should be a string that is
+ * one or more space-delimited class names.
+ *
+ * 3. If the expression evaluates to an object, then for each key-value pair of the
+ * object with a truthy value the corresponding key is used as a class name.
+ *
+ * The directive won't add duplicate classes if a particular class was already set.
+ *
+ * When the expression changes, the previously added classes are removed and only then the
+ * new classes are added.
+ *
+ * @animations
+ * **add** - happens just before the class is applied to the elements
+ *
+ * **remove** - happens just before the class is removed from the element
+ *
+ * @element ANY
+ * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
+ *   of the evaluation can be a string representing space delimited class
+ *   names, an array, or a map of class names to boolean values. In the case of a map, the
+ *   names of the properties whose values are truthy will be added as css classes to the
+ *   element.
+ *
+ * @example Example that demonstrates basic bindings via ngClass directive.

-   * @name ngModel.NgModelController#$setViewValue
-   *
-   * @description
-   * Update the view value.
-   *
-   * This method should be called when an input directive want to change the view value; typically,
-   * this is done from within a DOM event handler.
-   *
-   * For example {@link ng.directive:input input} calls it when the value of the input changes and
-   * {@link ng.directive:select select} calls it when an option is selected.
-   *
-   * If the new `value` is an object (rather than a string or a number), we should make a copy of the
-   * object before passing it to `$setViewValue`.  This is because `ngModel` does not perform a deep
-   * watch of objects, it only looks for a change of identity. If you only change the property of
-   * the object then ngModel will not realise that the object has changed and will not invoke the
-   * `$parsers` and `$validators` pipelines.
-   *
-   * For this reason, you should not change properties of the copy once it has been passed to
-   * `$setViewValue`. Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * When this method is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute.
-   *
-   * Lastly, all the registered change listeners, in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   *
-   * Note that calling this function does not trigger a `$digest`.

- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations.

+ * This directive can be applied only within the scope of an
+ * {@link ng.directive:ngRepeat ngRepeat}.
  *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}

- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid` is set if the model is valid.
- *  - `ng-invalid` is set if the model is invalid.
- *  - `ng-pristine` is set if the model is pristine.
- *  - `ng-dirty` is set if the model is dirty.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes are: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
+ * @element ANY
+ * @param {expression} ngClassEven {@link guide/expression Expression} to eval. The
+ *   result of the evaluation can be a string representing space delimited class names or an array.
  *

+/**
+ * @ngdoc directive
+ * @name ngCloak
+ * @restrict AC
  *
- * ## Binding to a getter/setter
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
  *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different than what the model exposes
- * to the view.
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
+ * of the browser view.
  *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
+ * `angular.min.js`.
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
  *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
+ * ```css
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * ```
  *
- * The following example shows how to use `ngModel` with a getter/setter:
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
+ * the compiled element visible.
+ *
+ * For the best result, the `angular.js` script must be loaded in the head section of the html
+ * document; alternatively, the css rule above must be included in the external stylesheet of the
+ * application.
+ *

 /**
  * @ngdoc directive
- * @name ngChange
+ * @name ngController
  *
  * @description
- * Evaluate the given expression when the user changes the input.
- * The expression is evaluated immediately, unlike the JavaScript onchange event
- * which only triggers at the end of a change (usually, when the user leaves the
- * form element or presses the return key).
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
  *
- * The `ngChange` expression is only evaluated when a change in the input value causes
- * a new value to be committed to the model.
+ * MVC components in angular:
  *
- * It will not be evaluated:
- * * if the value returned from the `$parsers` transformation pipeline has not changed
- * * if the input has continued to be invalid since the model will stay `null`
- * * if the model is changed programmatically and not by a change to the input value
+ * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
+ *   are accessed through bindings.
+ * * View — The template (HTML with data bindings) that is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
+ *   logic behind the application to decorate the scope with functions and values
  *
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
+ * again using `ng-controller` in the template itself.  This will cause the controller to be attached
+ * and executed twice.
  *
- * Note, this directive requires `ngModel` to be present.
+ * @element ANY
+ * @scope
+ * @priority 500
+ * @param {expression} ngController Name of a constructor function registered with the current
+ * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
+ * that on the current scope evaluates to a constructor function.
  *
- * @element input
- * @param {expression} ngChange {@link guide/expression Expression} to evaluate upon change
- * in input value.
+ * The controller instance can be published into a scope property by specifying
+ * `ng-controller="as propertyName"`.
+ *
+ * If the current `$controllerProvider` is configured to use globals (via
+ * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
+ * also be the name of a globally accessible constructor function (not recommended).
  *
  * @example
- * <example name="ngChange-directive" module="changeExample">
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Any changes to the data are automatically reflected
+ * in the View without the need for a manual update.
+ *
+ * Two different declaration styles are included below:
+ *
+ * * one binds methods and properties directly onto the controller using `this`:
+ * `ng-controller="SettingsController1 as settings"`
+ * * one injects `$scope` into the controller:
+ * `ng-controller="SettingsController2"`
+ *
+ * The second option is more common in the Angular community, and is generally used in boilerplates
+ * and in this guide. However, there are advantages to binding properties directly to the controller
+ * and avoiding scope.
+ *
+ * * Using `controller as` makes it obvious which controller you are accessing in the template when
+ * multiple controllers apply to an element.
+ * * If you are writing your controllers as classes you have easier access to the properties and
+ * methods, which will appear on the scope, from inside the controller code.
+ * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
+ * inheritance masking primitives.
+ *
+ * This example demonstrates the `controller as` syntax.

 /**
  * @ngdoc directive
- * @name ngList
+ * @name ngCsp
  *
+ * @element html
  * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+ * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
  *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- *   list item is respected. This implies that the user of the directive is responsible for
- *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- *   when joining the list items back together) and whitespace around each list item is stripped
- *   before it is added to the model.
+ * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
  *
- * ### Example with Validation
+ * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
+ * For Angular to be CSP compatible there are only two things that we need to do differently:
  *
- * <example name="ngList-directive" module="listExample">
- *   <file name="app.js">
- *      angular.module('listExample', [])
- *        .controller('ExampleController', ['$scope', function($scope) {
- *          $scope.names = ['morpheus', 'neo', 'trinity'];
- *        }]);
- *   </file>
- *   <file name="index.html">
- *    <form name="myForm" ng-controller="ExampleController">
- *      List: <input name="namesInput" ng-model="names" ng-list required>
- *      <span class="error" ng-show="myForm.namesInput.$error.required">
- *        Required!</span>
- *      <br>
- *      <tt>names = {{names}}</tt><br/>
- *      <tt>myForm.namesInput.$valid = {{myForm.namesInput.$valid}}</tt><br/>
- *      <tt>myForm.namesInput.$error = {{myForm.namesInput.$error}}</tt><br/>
- *      <tt>myForm.$valid = {{myForm.$valid}}</tt><br/>
- *      <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br/>
- *     </form>
- *   </file>
- *   <file name="protractor.js" type="protractor">
- *     var listInput = element(by.model('names'));
- *     var names = element(by.exactBinding('names'));
- *     var valid = element(by.binding('myForm.namesInput.$valid'));
- *     var error = element(by.css('span.error'));
+ * - don't use `Function` constructor to generate optimized value getters
+ * - don't inject custom stylesheet into the document
  *
- *     it('should initialize to model', function() {
- *       expect(names.getText()).toContain('["morpheus","neo","trinity"]');
- *       expect(valid.getText()).toContain('true');
- *       expect(error.getCssValue('display')).toBe('none');
- *     });
+ * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
+ * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
+ * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
+ * be raised.
  *
- *     it('should be invalid if empty', function() {
- *       listInput.clear();
- *       listInput.sendKeys('');
+ * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
+ * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
+ * To make those directives work in CSP mode, include the `angular-csp.css` manually.
  *
- *       expect(names.getText()).toContain('');
- *       expect(valid.getText()).toContain('false');
- *       expect(error.getCssValue('display')).not.toBe('none');
- *     });
- *   </file>
- * </example>
+ * Angular tries to autodetect if CSP is active and automatically turn on the CSP-safe mode. This
+ * autodetection however triggers a CSP error to be logged in the console:
  *
- * ### Example - splitting on whitespace
- * <example name="ngList-directive-newlines">
- *   <file name="index.html">
- *    <textarea ng-model="list" ng-list="&#10;" ng-trim="false"></textarea>
- *    <pre>{{ list | json }}</pre>
- *   </file>
- *   <file name="protractor.js" type="protractor">
- *     it("should split the text by newlines", function() {
- *       var listInput = element(by.model('list'));
- *       var output = element(by.binding('list | json'));
- *       listInput.sendKeys('abc\ndef\nghi');
- *       expect(output.getText()).toContain('[\n  "abc",\n  "def",\n  "ghi"\n]');
- *     });
- *   </file>
- * </example>
+ * ```
+ * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
+ * script in the following Content Security Policy directive: "default-src 'self'". Note that
+ * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
+ * ```
  *
- * @element input
- * @param {string=} ngList optional delimiter that should be used to split the value.

 /**
  * @ngdoc directive
- * @name ngModelOptions
+ * @name ngDblclick
  *
  * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that the actual update only
- * takes place when a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different than the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
+ * The `ngDblclick` directive allows you to specify custom behavior on a dblclick event.
  *
- * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
+ * @element ANY
+ * @priority 0
+ * @param {expression} ngDblclick {@link guide/expression Expression} to evaluate upon
+ * a dblclick. (The Event object is available as `$event`)
  *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
+ * @example
+   <example>
+     <file name="index.html">
+      <button ng-dblclick="count = count + 1" ng-init="count=0">
+        Increment (on double click)
+      </button>

+/**
+ * @ngdoc directive
+ * @name ngMousedown
  *
- * `ngModelOptions` has an effect on the element it's declared on and its descendants.
+ * @description
+ * The ngMousedown directive allows you to specify custom behavior on mousedown event.
  *
- * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
- *   - `updateOn`: string specifying which event should be the input bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 500, 'blur': 0} }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . Right now, the only supported value is `'UTC'`,
- *     otherwise the default timezone of the browser will be used.
+ * @element ANY
+ * @priority 0
+ * @param {expression} ngMousedown {@link guide/expression Expression} to evaluate upon
+ * mousedown. ({@link guide/expression#-event- Event object is available as `$event`})

+     <file name="index.html">

-  The following example shows how to override immediate updates. Changes on the inputs within the
-  form will update the model only when the control loses focus (blur event). If `escape` key is
-  pressed while the input field is focused, the value is reset to the value in the current model.

  *
  * @description
- * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
- * with the value of a given expression, and to update the text content when the value of that
- * expression changes.
- *
- * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
- * `{{ expression }}` which is similar but less verbose.
- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the page is loading.
- *
- * An alternative solution to this problem would be using the

  * @description
- * Creates a binding that will innerHTML the result of evaluating the `expression` into the current

- * is available, for example, by including {@link ngSanitize} in your module's dependencies (not in

- * include "angular-sanitize.js" in your application.
+ * Specify custom behavior on mouseleave event.
  *
- * You may also bypass sanitization for values you know are safe. To do so, bind to
- * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example

- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
+ * Note: As the `focus` event is executed synchronously when calling `input.focus()`
+ * AngularJS executes the expression using `scope.$evalAsync` if the event is fired
+ * during an `$apply` to ensure a consistent state.
  *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.

- * one or more space-delimited class names.
+ * @example
+ * See {@link ng.directive:ngClick ngClick}
+ */
+
+/**
+ * @ngdoc directive
+ * @name ngBlur
  *
- * 3. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
+ * @description
+ * Specify custom behavior on blur event.
  *
- * The directive won't add duplicate classes if a particular class was already set.
+ * A [blur event](https://developer.mozilla.org/en-US/docs/Web/Events/blur) fires when
+ * an element has lost focus.
  *
- * When the expression changes, the previously added classes are removed and only then the
- * new classes are added.
+ * Note: As the `blur` event is executed synchronously also during DOM manipulations
+ * (e.g. removing a focussed input),
+ * AngularJS executes the expression using `scope.$evalAsync` if the event is fired
+ * during an `$apply` to ensure a consistent state.

-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link ng.$animate#addClass $animate.addClass} and
-   {@link ng.$animate#removeClass $animate.removeClass}.

 /**
  * @ngdoc directive
- * @name ngCloak
- * @restrict AC
+ * @name ngIf
+ * @restrict A
  *
  * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
  *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property.  A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
  *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored.  The scope created within `ngIf` inherits from
+ * its parent scope using
+ * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
  *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
+ * is if an element's class attribute is directly modified after it's compiled, using something like
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
+ * the added class will be lost because the original compiled state is used to regenerate the element.
  *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
+ * and `leave` effects.
  *
- * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
- * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
- * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.
+ * @animations
+ * enter - happens just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container
+ * leave - happens just before the `ngIf` contents are removed from the DOM
  *
  * @element ANY
+ * @scope
+ * @priority 600
+ * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
+ *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
+ *     element is added to the DOM tree.
  *
  * @example
-   <example>
-     <file name="index.html">
-        <div id="template1" ng-cloak>{{ 'hello' }}</div>
-        <div id="template2" ng-cloak class="ng-cloak">{{ 'hello IE7' }}</div>

  * @ngdoc directive
- * @name ngController
+ * @name ngInclude
+ * @restrict ECA
  *
  * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
+ * Fetches, compiles and includes an external HTML fragment.
  *
- * MVC components in angular:
+ * By default, the template URL is restricted to the same domain and protocol as the
+ * application document. This is done by calling {@link $sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on it. To load templates from other domains or protocols
+ * you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist them} or
+ * {@link $sce#trustAsResourceUrl wrap them} as trusted values. Refer to Angular's {@link
+ * ng.$sce Strict Contextual Escaping}.
  *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
+ * In addition, 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 may further restrict whether the template is successfully loaded.
+ * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
+ * access on some browsers.
  *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
+ * @animations
+ * enter - animation is used to bring new content into the browser.
+ * leave - animation is used to animate existing content away.
+ *
+ * The enter and leave animation occur concurrently.
  *
- * @element ANY
  * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
+ * @priority 400
  *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
+ * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
+ *                 make sure you wrap it in **single** quotes, e.g. `src="'myPartialTemplate.html'"`.
+ * @param {string=} onload Expression to evaluate when a new partial is loaded.
  *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not recommended).
+ * @param {string=} autoscroll Whether `ngInclude` should call {@link ng.$anchorScroll
+ *                  $anchorScroll} to scroll the viewport after the content is loaded.
+ *
+ *                  - If the attribute is not set, disable scrolling.
+ *                  - If the attribute is set without value, enable scrolling.
+ *                  - Otherwise enable scrolling only if the expression evaluates to truthy value.
  *
  * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.

- * The second option is more common in the Angular community, and is generally used in boilerplates

- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when

- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
- *
- * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
- *
- * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
- * For Angular to be CSP compatible there are only two things that we need to do differently:
- *
- * - don't use `Function` constructor to generate optimized value getters
- * - don't inject custom stylesheet into the document
- *
- * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
- * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
- * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
- * be raised.
- *
- * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
- * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
- * To make those directives work in CSP mode, include the `angular-csp.css` manually.
- *
- * Angular tries to autodetect if CSP is active and automatically turn on the CSP-safe mode. This
- * autodetection however triggers a CSP error to be logged in the console:
+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+ * listening to DOM events.
+ * Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding to control elements.
+ * Angular provides this DOM logic for most {@link input `input`} elements.
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
  *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
+ * @example
+ * ### Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
  *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on the root element of the application or on the `angular.js` script tag, whichever
- * appears first in the html document.
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.
  *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+ * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+ * that content using the `$sce` service.
  *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
-  * @example

-      // csp mode in our http server!

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * enter - happens just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container
- * leave - happens just before the `ngIf` contents are removed from the DOM
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
- *     element is added to the DOM tree.
- *
- * @example

+   * Update the view value.
+   *
+   * This method should be called when an input directive want to change the view value; typically,
+   * this is done from within a DOM event handler.
+   *
+   * For example {@link ng.directive:input input} calls it when the value of the input changes and
+   * {@link ng.directive:select select} calls it when an option is selected.
+   *
+   * If the new `value` is an object (rather than a string or a number), we should make a copy of the
+   * object before passing it to `$setViewValue`.  This is because `ngModel` does not perform a deep
+   * watch of objects, it only looks for a change of identity. If you only change the property of
+   * the object then ngModel will not realise that the object has changed and will not invoke the
+   * `$parsers` and `$validators` pipelines.
+   *
+   * For this reason, you should not change properties of the copy once it has been passed to
+   * `$setViewValue`. Otherwise you may cause the model value on the scope to change incorrectly.
+   *
+   * When this method is called, the new `value` will be staged for committing through the `$parsers`
+   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+   * value sent directly for processing, finally to be applied to `$modelValue` and then the
+   * **expression** specified in the `ng-model` attribute.
+   *
+   * Lastly, all the registered change listeners, in the `$viewChangeListeners` list, are called.
+   *
+   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+   * and the `default` trigger is not listed, all those actions will remain pending until one of the
+   * `updateOn` events is triggered on the DOM element.
+   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+   * directive is used with a custom debounce for this particular event.

+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a

  *
- * @param {Object} angularEvent Synthetic event object.
- * @param {String} src URL of content to load.
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations.
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:
+ *
+ *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+ *
+ * For basic examples, how to use `ngModel`, see:
+ *
+ *  - {@link ng.directive:input input}
+ *    - {@link input[text] text}
+ *    - {@link input[checkbox] checkbox}
+ *    - {@link input[radio] radio}
+ *    - {@link input[number] number}
+ *    - {@link input[email] email}
+ *    - {@link input[url] url}
+ *    - {@link input[date] date}
+ *    - {@link input[datetime-local] datetime-local}
+ *    - {@link input[time] time}
+ *    - {@link input[month] month}
+ *    - {@link input[week] week}
+ *  - {@link ng.directive:select select}
+ *  - {@link ng.directive:textarea textarea}
+ *
+ * # CSS classes
+ * The following CSS classes are added and removed on the associated input/select/textarea element
+ * depending on the validity of the model.
+ *
+ *  - `ng-valid`: the model is valid
+ *  - `ng-invalid`: the model is invalid
+ *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+ *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+ *  - `ng-pristine`: the control hasn't been interacted with yet
+ *  - `ng-dirty`: the control has been interacted with
+ *  - `ng-touched`: the control has been blurred
+ *  - `ng-untouched`: the control hasn't been blurred
+ *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ * ## Animation Hooks
+ *
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
+ * on the input element which is attached to the model. These classes are: `.ng-pristine`, `.ng-dirty`,
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style an input element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * <pre>
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-input {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-input.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
+ * </pre>
+ *
+ * @example
+ * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
+     <file name="index.html">
+       <script>
+        angular.module('inputExample', [])
+          .controller('ExampleController', ['$scope', function($scope) {
+            $scope.val = '1';
+          }]);
+       </script>
+       <style>
+         .my-input {
+           -webkit-transition:all linear 0.5s;
+           transition:all linear 0.5s;
+           background: transparent;
+         }
+         .my-input.ng-invalid {
+           color:white;
+           background: red;
+         }
+       </style>
+       Update input to see transitions when valid/invalid.
+       Integer is a valid value.
+       <form name="testForm" ng-controller="ExampleController">
+         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input" />
+       </form>
+     </file>
+ * </example>
+ *
+ * ## Binding to a getter/setter
+ *
+ * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+ * function that returns a representation of the model when called with zero arguments, and sets
+ * the internal state of a model when called with an argument. It's sometimes useful to use this
+ * for models that have an internal representation that's different than what the model exposes
+ * to the view.
+ *
+ * <div class="alert alert-success">
+ * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
+ * frequently than other parts of your code.
+ * </div>
+ *
+ * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+ * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+ * a `<form>`, which will enable this behavior for all `<input>`s within it. See
+ * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
+ *
+ * The following example shows how to use `ngModel` with a getter/setter:
+ *
+ * @example
+ * <example name="ngModel-getter-setter" module="getterSetterExample">
+     <file name="index.html">
+       <div ng-controller="ExampleController">
+         <form name="userForm">
+           Name:
+           <input type="text" name="userName"
+                  ng-model="user.name"
+                  ng-model-options="{ getterSetter: true }" />
+         </form>
+         <pre>user.name = <span ng-bind="user.name()"></span></pre>
+       </div>
+     </file>
+     <file name="app.js">
+       angular.module('getterSetterExample', [])
+         .controller('ExampleController', ['$scope', function($scope) {
+           var _name = 'Brian';
+           $scope.user = {
+             name: function(newName) {
+              // Note that newName can be undefined for two reasons:
+              // 1. Because it is called as a getter and thus called with no arguments
+              // 2. Because the property should actually be set to undefined. This happens e.g. if the
+              //    input is invalid
+              return arguments.length ? (_name = newName) : _name;
+             }

 /**
  * @ngdoc directive
- * @name ngInit
- * @restrict AC
+ * @name ngModelOptions
  *
  * @description
- * The `ngInit` directive allows you to evaluate an expression in the
- * current scope.
+ * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
+ * events that will trigger a model update and/or a debouncing delay so that the actual update only
+ * takes place when a timer expires; this timer will be reset after another change takes place.
  *
- * <div class="alert alert-error">
- * The only appropriate use of `ngInit` is for aliasing special properties of
- * {@link ng.directive:ngRepeat `ngRepeat`}, as seen in the demo below. Besides this case, you
- * should use {@link guide/controller controllers} rather than `ngInit`
- * to initialize values on a scope.
- * </div>
- * <div class="alert alert-warning">
- * **Note**: If you have assignment in `ngInit` along with {@link ng.$filter `$filter`}, make
- * sure you have parenthesis for correct precedence:
- * <pre class="prettyprint">
- *   <div ng-init="test1 = (data | orderBy:'name')"></div>
- * </pre>
- * </div>
+ * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
+ * be different than the value in the actual model. This means that if you update the model you
+ * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
+ * order to make sure it is synchronized with the model and that any debounced action is canceled.
  *
- * @priority 450
+ * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
+ * method is by making sure the input is placed inside a form that has a `name` attribute. This is
+ * important because `form` controllers are published to the related scope under the name in their
+ * `name` attribute.
  *
- * @element ANY
- * @param {expression} ngInit {@link guide/expression Expression} to eval.
+ * Any pending changes will take place immediately when an enclosing form is submitted via the
+ * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * `ngModelOptions` has an effect on the element it's declared on and its descendants.
+ *
+ * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
+ *   - `updateOn`: string specifying which event should the input be bound to. You can set several
+ *     events using an space delimited list. There is a special event called `default` that
+ *     matches the default events belonging of the control.
+ *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+ *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+ *     custom value for each event. For example:
+ *     `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 500, 'blur': 0} }"`
+ *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+ *     not validate correctly instead of the default behavior of setting the model to undefined.
+ *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+       `ngModel` as getters/setters.
+ *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+ *     `<input type="date">`, `<input type="time">`, ... . Right now, the only supported value is `'UTC'`,
+ *     otherwise the default timezone of the browser will be used.

+  The following example shows how to override immediate updates. Changes on the inputs within the
+  form will update the model only when the control loses focus (blur event). If `escape` key is
+  pressed while the input field is focused, the value is reset to the value in the current model.

  * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
  * This may be useful when, for instance, nesting ngRepeats.
  *
+ * # Iterating over object properties
+ *
+ * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
+ * syntax:
+ *
+ * ```js
+ * <div ng-repeat="(key, value) in myObj"> ... </div>
+ * ```
+ *
+ * You need to be aware that the JavaScript specification does not define what order
+ * it will return the keys for an object. In order to have a guaranteed deterministic order
+ * for the keys, Angular versions up to and including 1.3 **sort the keys alphabetically**.
+ *
+ * If this is not desired, the recommended workaround is to convert your object into an array
+ * that is sorted into the order that you prefer before providing it to `ngRepeat`.  You could
+ * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
+ * or implement a `$watch` on the object yourself.
+ *
+ * In version 1.4 we will remove the sorting, since it seems that browsers generally follow the
+ * strategy of providing keys in the order in which they were defined, although there are exceptions
+ * when keys are deleted and reinstated.
+ *
+ *
+ * # Tracking and Duplicates
+ *
+ * When the contents of the collection change, `ngRepeat` makes the corresponding changes to the DOM:
+ *
+ * * When an item is added, a new instance of the template is added to the DOM.
+ * * When an item is removed, its template instance is removed from the DOM.
+ * * When items are reordered, their respective templates are reordered in the DOM.
+ *
+ * By default, `ngRepeat` does not allow duplicate items in arrays. This is because when
+ * there are duplicates, it is not possible to maintain a one-to-one mapping between collection
+ * items and DOM elements.
+ *
+ * If you do need to repeat duplicate items, you can substitute the default tracking behavior
+ * with your own using the `track by` expression.
+ *
+ * For example, you may track items by the index of each item in the collection, using the
+ * special scope property `$index`:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * You may use arbitrary expressions in `track by`, including references to custom functions
+ * on the scope:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * If you are working with objects that have an identifier property, you can track
+ * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
+ * will not have to rebuild the DOM elements for items it has already rendered, even if the
+ * JavaScript objects in the collection have been substituted for new ones:
+ * ```html
+ *    <div ng-repeat="model in collection track by model.id">
+ *      {{model.name}}
+ *    </div>
+ * ```
+ *
+ * When no `track by` expression is provided, it is equivalent to tracking by the built-in
+ * `$id` function, which tracks items by their identity:
+ * ```html
+ *    <div ng-repeat="obj in collection track by $id(obj)">
+ *      {{obj.prop}}
+ *    </div>
+ * ```
+ *
  * # Special repeat start and end points
  * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
  * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.

+ *
+ * <div class="alert alert-warning">
+ * Do not use `select` **`as`** and **`track by`** in the same expression. They are not designed to work together.
  * </div>
  *
- * **Note:** Using `select as` together with `trackexpr` is not recommended.
- * Reasoning:
- * - Example: &lt;select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected"&gt;
- *   values: [{id: 1, label: 'aLabel', subItem: {name: 'aSubItem'}}, {id: 2, label: 'bLabel', subItem: {name: 'bSubItem'}}],
- *   $scope.selected = {name: 'aSubItem'};
- * - track by is always applied to `value`, with the purpose of preserving the selection,
- *   (to `item` in this case)
- * - to calculate whether an item is selected we do the following:
- *   1. apply `track by` to the values in the array, e.g.
- *      In the example: [1,2]
- *   2. apply `track by` to the already selected value in `ngModel`:
- *      In the example: this is not possible, as `track by` refers to `item.id`, but the selected
- *      value from `ngModel` is `{name: aSubItem}`.
+ * Consider the following example:
+ *
+ * ```html
+ * <select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected">
+ * ```
+ *
+ * ```js
+ * $scope.values = [{
+ *   id: 1,
+ *   label: 'aLabel',
+ *   subItem: { name: 'aSubItem' }
+ * }, {
+ *   id: 2,
+ *   label: 'bLabel',
+ *   subItem: { name: 'bSubItem' }
+ * }];
+ *
+ * $scope.selected = { name: 'aSubItem' };
+ * ```
+ *
+ * With the purpose of preserving the selection, the **`track by`** expression is always applied to the element
+ * of the data source (to `item` in this example). To calculate whether an element is selected, we do the
+ * following:
+ *
+ * 1. Apply **`track by`** to the elements in the array. In the example: `[1, 2]`
+ * 2. Apply **`track by`** to the already selected value in `ngModel`.
+ *    In the example: this is not possible as **`track by`** refers to `item.id`, but the selected
+ *    value from `ngModel` is `{name: 'aSubItem'}`, so the **`track by`** expression is applied to
+ *    a wrong object, the selected element can't be found, `<select>` is always reset to the "not
+ *    selected" option.
