What is Maverix?

\n\n

Maverix is a maccish bootstrap theme and application boilerplate. It gives your web-apps a\n native look and feel and bundles\n AngularJS and other components such as jQuery,\n Flot and rangeslider.js\n

\n\n

It is perfect to be used for apps that are based on HTML App Containers such as:\n

\n

\n
\n

Design Decisions

\n\n
\n

Closest possible to native

\n\n\n

All controls and Elements are carefully designed to perfectly fit into the native mac environment.

\n\n

Non Responsive (for now...)

\n\n

Desktop Apps don't need to run on thousands of different devices and\n viewports. You are the master of setting a minimum-viewport and the app won't get smaller than this. If\n you\n are\n using Maverix Theme in a traditional web-app it is also okay for Admin Backends that don't need\n responsive\n layout.\n

\n\n

Built on Bootstrap and Less

\n\n

Twitters Bootstrap comes bundled with tons of useful styles and add ons and\n allows beginners and masters to get started quickly (grid positioning, etc.). The maverix styles are\n enhancing bootstrap and are written in\n less.css\n

\n\n

Webkit first

\n\n

\n Maverix Theme is primarily made to enable app container based web-apps to look like native OS X Apps.\n So webkit is the primary engine when releasing new components. However this doesn't mean that other\n browsers\n are totally unsupported. Maverix Theme is tested on Safari, Firefox and Chrome on OS X.\n

\n
\n
\n

Bundled with AngularJS

\n\n

AngularJS is one of the best Javascript App Frameworks\n available today and so Maverix Theme comes bundled with AngularJS including fully working routing to get you\n started fast. Anyways, AngularJS usage is optional.

\n\n

Heading One

\n

The Heading One style should be used rarely and only on specifically crafted pages. Make Sure it fits well if you\n decide to make use of it ;).

\n

Heading Two

\n

Headind Two is the default heading for this Theme. If you only present text after Heading Two you can also add an\n \".indent\" class to the text container(e.g. p-tag).

\n

This looks like this

\n

This text is intended and looks awesome below a Heading Two.

\n
\n

Heading Three

\n

Use heading three only if necessary and only to add some extra grouping below a Heading Two. Usually it fits better\n to use nav-tabs to for grouping and then make use of Heading Twos.

This\n * module will be loaded into the {@link auto.$injector} when the application is bootstrapped and\n * should contain the application code needed or have dependencies on other modules that will\n * contain the code. See {@link angular.module} for more information.\n *\n * In the example below if the `ngApp` directive were not placed on the `html` element then the\n * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`\n * would not be resolved to `3`.\n *\n * `ngApp` is the easiest, and most common, way to bootstrap an application.\n *\n \n \n

If jQuery is not available, `angular.element`\n * delegates to Angular's built-in subset of jQuery, called \"jQuery lite\" or \"jqLite.\"\n *\n *
jqLite is a tiny, API-compatible subset of jQuery that allows\n * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most\n * commonly needed functionality with the goal of having a very small footprint.
\n *\n * To use jQuery, simply load it before `DOMContentLoaded` event fired.\n *\n *
**Note:** all element references in Angular are always wrapped with jQuery or\n * jqLite; they are never raw DOM references.
\n *\n * ## Angular's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/)\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/)\n * - [`attr()`](http://api.jquery.com/attr/)\n * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData\n * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n * - [`clone()`](http://api.jquery.com/clone/)\n * - [`contents()`](http://api.jquery.com/contents/)\n * - [`css()`](http://api.jquery.com/css/)\n * - [`data()`](http://api.jquery.com/data/)\n * - [`empty()`](http://api.jquery.com/empty/)\n * - [`eq()`](http://api.jquery.com/eq/)\n * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [`hasClass()`](http://api.jquery.com/hasClass/)\n * - [`html()`](http://api.jquery.com/html/)\n * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors\n * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n * - [`prepend()`](http://api.jquery.com/prepend/)\n * - [`prop()`](http://api.jquery.com/prop/)\n * - [`ready()`](http://api.jquery.com/ready/)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/)\n * - [`removeClass()`](http://api.jquery.com/removeClass/)\n * - [`removeData()`](http://api.jquery.com/removeData/)\n * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n * - [`text()`](http://api.jquery.com/text/)\n * - [`toggleClass()`](http://api.jquery.com/toggleClass/)\n * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.\n * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces\n * - [`val()`](http://api.jquery.com/val/)\n * - [`wrap()`](http://api.jquery.com/wrap/)\n *\n * ## jQuery/jqLite Extras\n * Angular also provides the following additional methods and events to both jQuery and jqLite:\n *\n * ### Events\n * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n * element before it is removed.\n *\n * ### Methods\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n * retrieves controller associated with the `ngController` directive. If `name` is provided as\n * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n * `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n * element or its parent.\n * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n * current element. This getter should be used only on elements that contain a directive which starts a new isolate\n * scope. Calling `scope()` on this element always returns the original non-isolate scope.\n * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n * parent element is reached.\n *\n * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n * @returns {Object} jQuery object.\n */\n\nvar jqCache = JQLite.cache = {},\n jqName = JQLite.expando = 'ng-' + new Date().getTime(),\n jqId = 1,\n addEventListenerFn = (window.document.addEventListener\n ? function(element, type, fn) {element.addEventListener(type, fn, false);}\n : function(element, type, fn) {element.attachEvent('on' + type, fn);}),\n removeEventListenerFn = (window.document.removeEventListener\n ? function(element, type, fn) {element.removeEventListener(type, fn, false); }\n : function(element, type, fn) {element.detachEvent('on' + type, fn); });\n\n/*\n * !!!

\n * **Note:** This document is an in-depth reference of all directive options.\n * For a gentle introduction to directives with examples of common use cases,\n * see the {@link guide/directive directive guide}.\n *
\n *\n * ## Comprehensive Directive API\n *\n * There are many different options for a directive.\n *\n * The difference resides in the return value of the factory function.\n * You can either return a \"Directive Definition Object\" (see below) that defines the directive properties,\n * or just the `postLink` function (all other properties will have the default values).\n *\n *
\n * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n *
\n *\n * Here's an example directive declared with a Directive Definition Object:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * priority: 0,\n * template: '
', // or // function(tElement, tAttrs) { ... },\n * // or\n * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },\n * replace: false,\n * transclude: false,\n * restrict: 'A',\n * scope: false,\n * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n * controllerAs: 'stringAlias',\n * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n * compile: function compile(tElement, tAttrs, transclude) {\n * return {\n * pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n * post: function postLink(scope, iElement, iAttrs, controller) { ... }\n * }\n * // or\n * // return function postLink( ... ) { ... }\n * },\n * // or\n * // link: {\n * // pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n * // post: function postLink(scope, iElement, iAttrs, controller) { ... }\n * // }\n * // or\n * // link: function postLink( ... ) { ... }\n * };\n * return directiveDefinitionObject;\n * });\n * ```\n *\n *
\n * **Note:** Any unspecified options will use the default value. You can see the default values below.\n *
\n *\n * Therefore the above can be simplified as:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * link: function postLink(scope, iElement, iAttrs) { ... }\n * };\n * return directiveDefinitionObject;\n * // or\n * // return function postLink(scope, iElement, iAttrs) { ... }\n * });\n * ```\n *\n *\n *\n * ### Directive Definition Object\n *\n * The directive definition object provides instructions to the {@link ng.$compile\n * compiler}. The attributes are:\n *\n * #### `priority`\n * When there are multiple directives defined on a single DOM element, sometimes it\n * is necessary to specify the order in which the directives are applied. The `priority` is used\n * to sort the directives before their `compile` functions get called. Priority is defined as a\n * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n * are also run in priority order, but post-link functions are run in reverse order. The order\n * of directives with the same priority is undefined. The default priority is `0`.\n *\n * #### `terminal`\n * If set to true then the current `priority` will be the last set of directives\n * which will execute (any directives at the current priority will still execute\n * as the order of execution on same `priority` is undefined).\n *\n * #### `scope`\n * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the\n * same element request a new scope, only one new scope is created. The new scope rule does not\n * apply for the root of the template since the root of the template always gets a new scope.\n *\n * **If set to `{}` (object hash),** then a new \"isolate\" scope is created. The 'isolate' scope differs from\n * normal scope in that it does not prototypically inherit from the parent scope. This is useful\n * when creating reusable components, which should not accidentally read or modify data in the\n * parent scope.\n *\n * The 'isolate' scope takes an object hash which defines a set of local scope properties\n * derived from the parent scope. These local properties are useful for aliasing values for\n * templates. Locals definition is a hash of local scope property to its source:\n *\n * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n * always a string since DOM attributes are strings. If no `attr` name is specified then the\n * attribute name is assumed to be the same as the local name.\n * Given `` and widget definition\n * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect\n * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the\n * `localName` property on the widget scope. The `name` is read from the parent scope (not\n * component scope).\n *\n * * `=` or `=attr` - set up bi-directional binding between a local scope property and the\n * parent scope property of name defined via the value of the `attr` attribute. If no `attr`\n * name is specified then the attribute name is assumed to be the same as the local name.\n * Given `` and widget definition of\n * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the\n * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected\n * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent\n * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You\n * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional.\n *\n * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.\n * If no `attr` name is specified then the attribute name is assumed to be the same as the\n * local name. Given `` and widget definition of\n * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to\n * a function wrapper for the `count = count + value` expression. Often it's desirable to\n * pass data from the isolated scope via an expression and to the parent scope, this can be\n * done by passing a map of local variable names and values into the expression wrapper fn.\n * For example, if the expression is `increment(amount)` then we can specify the amount value\n * by calling the `localFn` as `localFn({amount: 22})`.\n *\n *\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and it is shared with other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$scope` - Current scope associated with the element\n * * `$element` - Current element\n * * `$attrs` - Current attributes object for the element\n * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope.\n * The scope can be overridden by an optional first argument.\n * `function([scope], cloneLinkingFn)`.\n *\n *\n * #### `require`\n * Require another directive and inject its controller as the fourth argument to the linking function. The\n * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the\n * injected argument will be an array in corresponding order. If no such directive can be\n * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:\n *\n * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.\n * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.\n * * `^` - Locate the required controller by searching the element's parents. Throw an error if not found.\n * * `?^` - Attempt to locate the required controller by searching the element's parents or pass `null` to the\n * `link` fn if not found.\n *\n *\n * #### `controllerAs`\n * Controller alias at the directive scope. An alias for the controller so it\n * can be referenced at the directive template. The directive needs to define a scope for this\n * configuration to be used. Useful in the case when directive is used as component.\n *\n *\n * #### `restrict`\n * String of subset of `EACM` which restricts the directive to a specific directive\n * declaration style. If omitted, the default (attributes only) is used.\n *\n * * `E` - Element name: ``\n * * `A` - Attribute (default): `
`\n * * `C` - Class: `
`\n * * `M` - Comment: ``\n *\n *\n * #### `template`\n * replace the current element with the contents of the HTML. The replacement process\n * migrates all of the attributes / classes from the old element to the new one. See the\n * {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive\n * Directives Guide} for an example.\n *\n * You can specify `template` as a string representing the template or as a function which takes\n * two arguments `tElement` and `tAttrs` (described in the `compile` function api below) and\n * returns a string value representing the template.\n *\n *\n * #### `templateUrl`\n * Same as `template` but the template is loaded from the specified URL. Because\n * the template loading is asynchronous the compilation/linking is suspended until the template\n * is loaded.\n *\n * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n * a string value representing the url. In either case, the template URL is passed through {@link\n * api/ng.$sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n *\n *\n * #### `replace`\n * specify where the template should be inserted. Defaults to `false`.\n *\n * * `true` - the template will replace the current element.\n * * `false` - the template will replace the contents of the current element.\n *\n *\n * #### `transclude`\n * compile the content of the element and make it available to the directive.\n * Typically used with {@link ng.directive:ngTransclude\n * ngTransclude}. The advantage of transclusion is that the linking function receives a\n * transclusion function which is pre-bound to the correct scope. In a typical setup the widget\n * creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`\n * scope. This makes it possible for the widget to have private state, and the transclusion to\n * be bound to the parent (pre-`isolate`) scope.\n *\n * * `true` - transclude the content of the directive.\n * * `'element'` - transclude the whole element including any directives defined at lower priority.\n *\n *\n * #### `compile`\n *\n * ```js\n * function compile(tElement, tAttrs, transclude) { ... }\n * ```\n *\n * The compile function deals with transforming the template DOM. Since most directives do not do\n * template transformation, it is not used often. Examples that require compile functions are\n * directives that transform template DOM, such as {@link\n * api/ng.directive:ngRepeat ngRepeat}, or load the contents\n * asynchronously, such as {@link ngRoute.directive:ngView ngView}. The\n * compile function takes the following arguments.\n *\n * * `tElement` - template element - The element where the directive has been declared. It is\n * safe to do template transformation on the element and child elements only.\n *\n * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n * between all directive compile functions.\n *\n * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n *\n *
\n * **Note:** The template instance and the link instance may be different objects if the template has\n * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n * should be done in a linking function rather than in a compile function.\n *
\n\n *
\n * **Note:** The compile function cannot handle directives that recursively use themselves in their\n * own templates or compile functions. Compiling these directives results in an infinite loop and a\n * stack overflow errors.\n *\n * This can be avoided by manually using $compile in the postLink function to imperatively compile\n * a directive's template instead of relying on automatic template compilation via `template` or\n * `templateUrl` declaration or manual compilation inside the compile function.\n *
\n *\n *
\n * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n * to the link function instead.\n *
\n\n * A compile function can have a return value which can be either a function or an object.\n *\n * * returning a (post-link) function - is equivalent to registering the linking function via the\n * `link` property of the config object when the compile function is empty.\n *\n * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n * control when a linking function should be called during the linking phase. See info about\n * pre-linking and post-linking functions below.\n *\n *\n * #### `link`\n * This property is used only if the `compile` property is not defined.\n *\n * ```js\n * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n * ```\n *\n * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n * executed after the template has been cloned. This is where most of the directive logic will be\n * put.\n *\n * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n *\n * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n * manipulate the children of the element only in `postLink` function since the children have\n * already been linked.\n *\n * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n * between all directive linking functions.\n *\n * * `controller` - a controller instance - A controller instance if at least one directive on the\n * element defines a controller. The controller is shared among all the directives, which allows\n * the directives to use the controllers as a communication channel.\n *\n * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n * The scope can be overridden by an optional first argument. This is the same as the `$transclude`\n * parameter of directive controllers.\n * `function([scope], cloneLinkingFn)`.\n *\n *\n * #### Pre-linking function\n *\n * Executed before the child elements are linked. Not safe to do DOM transformation since the\n * compiler linking function will fail to locate the correct elements for linking.\n *\n * #### Post-linking function\n *\n * Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function.\n *\n * \n * ### Attributes\n *\n * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n * `link()` or `compile()` functions. It has a variety of uses.\n *\n * accessing *Normalized attribute names:*\n * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.\n * the attributes object allows for normalized access to\n * the attributes.\n *\n * * *Directive inter-communication:* All directives share the same instance of the attributes\n * object which allows the directives to use the attributes object as inter directive\n * communication.\n *\n * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n * allowing other directives to read the interpolated value.\n *\n * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n * the only way to easily get the actual value because during the linking phase the interpolation\n * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n *\n * ```js\n * function linkingFn(scope, elm, attrs, ctrl) {\n * // get the attribute value\n * console.log(attrs.ngModel);\n *\n * // change the attribute\n * attrs.$set('ngModel', 'new value');\n *\n * // observe changes to interpolated attribute\n * attrs.$observe('ngModel', function(value) {\n * console.log('ngModel has changed value to ' + value);\n * });\n * }\n * ```\n *\n * Below is an example using `$compileProvider`.\n *\n *
\n * **Note**: Typically directives are registered with `module.directive`. The example below is\n * to illustrate how `$compile` works.\n *

Where:\n *\n * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n * called as:
`cloneAttachFn(clonedElement, scope)` where:\n *\n * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n * * `scope` - is the current scope with which the linking function is working with.\n *\n * Calling the linking function returns the element of the template. It is either the original\n * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n *\n * After linking the view is not updated until after a call to $digest which typically is done by\n * Angular automatically.\n *\n * If you need access to the bound view, there are two ways to do it:\n *\n * - If you are not asking the linking function to clone the template, create the DOM element(s)\n * before you send them to the compiler and keep this reference around.\n * ```js\n * var element = $compile('

{{total}}

')(scope);\n * ```\n *\n * - if on the other hand, you need the element to be cloned, the view reference from the original\n * example would not point to the clone, but rather to the original template that was cloned. In\n * this case, you can access the clone via the cloneAttachFn:\n * ```js\n * var templateElement = angular.element('

{{total}}

'),\n * scope = ....;\n *\n * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {\n * //attach the clone to DOM document at the right place\n * });\n *\n * //now we have reference to the cloned DOM via `clonedElement`\n * ```\n *\n *\n * For information on how the compiler works, see the\n * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.\n */\n\nvar $compileMinErr = minErr('$compile');\n\n/**\n * @ngdoc provider\n * @name $compileProvider\n * @function\n *\n * @description\n */\n$CompileProvider.$inject = ['$provide', '$$sanitizeUriProvider'];\nfunction $CompileProvider($provide, $$sanitizeUriProvider) {\n var hasDirectives = {},\n Suffix = 'Directive',\n COMMENT_DIRECTIVE_REGEXP = /^\\s*directive\\:\\s*([\\d\\w\\-_]+)\\s+(.*)$/,\n CLASS_DIRECTIVE_REGEXP = /(([\\d\\w\\-_]+)(?:\\:([^;]+))?;?)/;\n\n // Ref: http://developers.whatwg.org/webappapis.html#event-handler-idl-attributes\n // The assumption is that future DOM event attribute names will begin with\n // 'on' and be composed of only English letters.\n var EVENT_HANDLER_ATTR_REGEXP = /^(on[a-z]+|formaction)$/;\n\n /**\n * @ngdoc method\n * @name $compileProvider#directive\n * @function\n *\n * @description\n * Register a new directive with the compiler.\n *\n * @param {string|Object} name Name of the directive in camel-case (i.e. ngBind which\n * will match as ng-bind), or an object map of directives where the keys are the\n * names and the values are the factories.\n * @param {Function|Array} directiveFactory An injectable directive factory function.

While for simple usage patterns this doesn't matter much, for advanced usage\n * it is important to familiarize yourself with these APIs and the guarantees they provide.\n *\n *\n * # General usage\n * The `$http` service is a function which takes a single argument — a configuration object —\n * that is used to generate an HTTP request and returns a {@link ng.$q promise}\n * with two $http specific methods: `success` and `error`.\n *\n * ```js\n * $http({method: 'GET', url: '/someUrl'}).\n * success(function(data, status, headers, config) {\n * // this callback will be called asynchronously\n * // when the response is available\n * }).\n * error(function(data, status, headers, config) {\n * // called asynchronously if an error occurs\n * // or server returns response with an error status.\n * });\n * ```\n *\n * Since the returned value of calling the $http function is a `promise`, you can also use\n * the `then` method to register callbacks, and these callbacks will receive a single argument –\n * an object representing the response. See the API signature and type info below for more\n * details.\n *\n * A response status code between 200 and 299 is considered a success status and\n * will result in the success callback being called. Note that if the response is a redirect,\n * XMLHttpRequest will transparently follow it, meaning that the error callback will not be\n * called for such responses.\n *\n * # Writing Unit Tests that use $http\n * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n * request using trained responses.\n *\n * ```\n * $httpBackend.expectGET(...);\n * $http.get(...);\n * $httpBackend.flush();\n * ```\n *\n * # Shortcut methods\n *\n * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n * request data must be passed in for POST/PUT requests.\n *\n * ```js\n * $http.get('/someUrl').success(successCallback);\n * $http.post('/someUrl', data).success(successCallback);\n * ```\n *\n * Complete list of shortcut methods:\n *\n * - {@link ng.$http#get $http.get}\n * - {@link ng.$http#head $http.head}\n * - {@link ng.$http#post $http.post}\n * - {@link ng.$http#put $http.put}\n * - {@link ng.$http#delete $http.delete}\n * - {@link ng.$http#jsonp $http.jsonp}\n *\n *\n * # Setting HTTP Headers\n *\n * The $http service will automatically add certain HTTP headers to all requests. These defaults\n * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n * object, which currently contains this default configuration:\n *\n * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n * - `Accept: application/json, text/plain, * / *`\n * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n * - `Content-Type: application/json`\n * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n * - `Content-Type: application/json`\n *\n * To add or overwrite these defaults, simply add or remove a property from these configuration\n * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n * with the lowercased HTTP method name as the key, e.g.\n * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.\n *\n * The defaults can also be set at runtime via the `$http.defaults` object in the same\n * fashion. For example:\n *\n * ```\n * module.run(function($http) {\n * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'\n * });\n * ```\n *\n * In addition, you can supply a `headers` property in the config object passed when\n * calling `$http(config)`, which overrides the defaults without changing them globally.\n *\n *\n * # Transforming Requests and Responses\n *\n * Both requests and responses can be transformed using transform functions. By default, Angular\n * applies these transformations:\n *\n * Request transformations:\n *\n * - If the `data` property of the request configuration object contains an object, serialize it\n * into JSON format.\n *\n * Response transformations:\n *\n * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n * - If JSON response is detected, deserialize it using a JSON parser.\n *\n * To globally augment or override the default transforms, modify the\n * `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse`\n * properties. These properties are by default an array of transform functions, which allows you\n * to `push` or `unshift` a new transformation function into the transformation chain. You can\n * also decide to completely override any default transformations by assigning your\n * transformation functions to these properties directly without the array wrapper. These defaults\n * are again available on the $http factory at run-time, which may be useful if you have run-time\n * services you wish to be involved in your transformations.\n *\n * Similarly, to locally override the request/response transforms, augment the\n * `transformRequest` and/or `transformResponse` properties of the configuration object passed\n * into `$http`.\n *\n *\n * # Caching\n *\n * To enable caching, set the request configuration `cache` property to `true` (to use default\n * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).\n * When the cache is enabled, `$http` stores the response from the server in the specified\n * cache. The next time the same request is made, the response is served from the cache without\n * sending a request to the server.\n *\n * Note that even if the response is served from cache, delivery of the data is asynchronous in\n * the same way that real requests are.\n *\n * If there are multiple GET requests for the same URL that should be cached using the same\n * cache, but the cache is not populated yet, only one request to the server will be made and\n * the remaining requests will be fulfilled using the response from the first request.\n *\n * You can change the default cache to a new object (built with\n * {@link ng.$cacheFactory `$cacheFactory`}) by updating the\n * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set\n * their `cache` property to `true` will now use this cache object.\n *\n * If you set the default cache to `false` then only requests that specify their own custom\n * cache object will be cached.\n *\n * # Interceptors\n *\n * Before you start creating interceptors, be sure to understand the\n * {@link ng.$q $q and deferred/promise APIs}.\n *\n * For purposes of global error handling, authentication, or any kind of synchronous or\n * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n * able to intercept requests before they are handed to the server and\n * responses before they are handed over to the application code that\n * initiated these requests. The interceptors leverage the {@link ng.$q\n * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n *\n * The interceptors are service factories that are registered with the `$httpProvider` by\n * adding them to the `$httpProvider.interceptors` array. The factory is called and\n * injected with dependencies (if specified) and returns the interceptor.\n *\n * There are two kinds of interceptors (and two kinds of rejection interceptors):\n *\n * * `request`: interceptors get called with http `config` object. The function is free to\n * modify the `config` or create a new one. The function needs to return the `config`\n * directly or as a promise.\n * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n * * `response`: interceptors get called with http `response` object. The function is free to\n * modify the `response` or create a new one. The function needs to return the `response`\n * directly or as a promise.\n * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n *\n *\n * ```js\n * // register the interceptor as a service\n * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n * return {\n * // optional method\n * 'request': function(config) {\n * // do something on success\n * return config || $q.when(config);\n * },\n *\n * // optional method\n * 'requestError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * },\n *\n *\n *\n * // optional method\n * 'response': function(response) {\n * // do something on success\n * return response || $q.when(response);\n * },\n *\n * // optional method\n * 'responseError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * }\n * };\n * });\n *\n * $httpProvider.interceptors.push('myHttpInterceptor');\n *\n *\n * // alternatively, register the interceptor via an anonymous factory\n * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n * return {\n * 'request': function(config) {\n * // same as above\n * },\n *\n * 'response': function(response) {\n * // same as above\n * }\n * };\n * });\n * ```\n *\n * # Response interceptors (DEPRECATED)\n *\n * Before you start creating interceptors, be sure to understand the\n * {@link ng.$q $q and deferred/promise APIs}.\n *\n * For purposes of global error handling, authentication or any kind of synchronous or\n * asynchronous preprocessing of received responses, it is desirable to be able to intercept\n * responses for http requests before they are handed over to the application code that\n * initiated these requests. The response interceptors leverage the {@link ng.$q\n * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.\n *\n * The interceptors are service factories that are registered with the $httpProvider by\n * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and\n * injected with dependencies (if specified) and returns the interceptor — a function that\n * takes a {@link ng.$q promise} and returns the original or a new promise.\n *\n * ```js\n * // register the interceptor as a service\n * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n * return function(promise) {\n * return promise.then(function(response) {\n * // do something on success\n * return response;\n * }, function(response) {\n * // do something on error\n * if (canRecover(response)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(response);\n * });\n * }\n * });\n *\n * $httpProvider.responseInterceptors.push('myHttpInterceptor');\n *\n *\n * // register the interceptor via an anonymous factory\n * $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {\n * return function(promise) {\n * // same as above\n * }\n * });\n * ```\n *\n *\n * # Security Considerations\n *\n * When designing web applications, consider security threats from:\n *\n * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n *\n * Both server and the client must cooperate in order to eliminate these threats. Angular comes\n * pre-configured with strategies that address these issues, but for this to work backend server\n * cooperation is required.\n *\n * ## JSON Vulnerability Protection\n *\n * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * allows third party website to turn your JSON resource URL into\n * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n * Angular will automatically strip the prefix before processing it as JSON.\n *\n * For example if your server needs to return:\n * ```js\n * ['one','two']\n * ```\n *\n * which is vulnerable to attack, your server can return:\n * ```js\n * )]}',\n * ['one','two']\n * ```\n *\n * Angular will strip the prefix, before processing the JSON.\n *\n *\n * ## Cross Site Request Forgery (XSRF) Protection\n *\n * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which\n * an unauthorized site can gain your user's private data. Angular provides a mechanism\n * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie\n * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only\n * JavaScript that runs on your domain could read the cookie, your server can be assured that\n * the XHR came from JavaScript running on your domain. The header will not be set for\n * cross-domain requests.\n *\n * To take advantage of this, your server needs to set a token in a JavaScript readable session\n * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n * that only JavaScript running on your domain could have sent the request. The token must be\n * unique for each user and must be verifiable by the server (to prevent the JavaScript from\n * making up its own tokens). We recommend that the token is a digest of your site's\n * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n * for added security.\n *\n * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName\n * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,\n * or the per-request config object.\n *\n *\n * @param {object} config Object describing the request to be made and how it should be\n * processed. The object has following properties:\n *\n * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.\n * - **params** – `{Object.}` – Map of strings or objects which will be turned\n * to `?key1=value1&key2=value2` after the url.

For the sake of performance, during the lexing phase we\n// disallow any \"dotted\" access to any member named \"constructor\".\n//\n// For reflective calls (a[b]) we check that the value of the lookup is not the Function constructor\n// while evaluating the expression, which is a stronger but more expensive test. Since reflective\n// calls are expensive anyway, this is not such a big deal compared to static dereferencing.\n//\n// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits\n// against the expression language, but not to prevent exploits that were enabled by exposing\n// sensitive JavaScript or browser apis on Scope.

The payoff\n * comes in the way of guarantees that promise and deferred APIs make, see\n * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.\n *\n * Additionally the promise api allows for composition that is very hard to do with the\n * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n * section on serial or parallel joining of promises.\n *\n *\n * # The Deferred API\n *\n * A new instance of deferred is constructed by calling `$q.defer()`.\n *\n * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n * that can be used for signaling the successful or unsuccessful completion, as well as the status\n * of the task.\n *\n * **Methods**\n *\n * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n * constructed via `$q.reject`, the promise will be rejected instead.\n * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n * resolving it with a rejection constructed via `$q.reject`.\n * - `notify(value)` - provides updates on the status of the promise's execution. This may be called\n * multiple times before the promise is either resolved or rejected.\n *\n * **Properties**\n *\n * - promise – `{Promise}` – promise object associated with this deferred.\n *\n *\n * # The Promise API\n *\n * A new promise instance is created when a deferred instance is created and can be retrieved by\n * calling `deferred.promise`.\n *\n * The purpose of the promise object is to allow for interested parties to get access to the result\n * of the deferred task when it completes.\n *\n * **Methods**\n *\n * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or\n * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously\n * as soon as the result is available. The callbacks are called with a single argument: the result\n * or rejection reason. Additionally, the notify callback may be called zero or more times to\n * provide a progress indication, before the promise is resolved or rejected.\n *\n * This method *returns a new promise* which is resolved or rejected via the return value of the\n * `successCallback`, `errorCallback`. It also notifies via the return value of the\n * `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback\n * method.\n *\n * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`\n *\n * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise,\n * but to do so without modifying the final value. This is useful to release resources or do some\n * clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n * more information.\n *\n * Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as\n * property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to\n * make your code IE8 and Android 2.x compatible.\n *\n * # Chaining promises\n *\n * Because calling the `then` method of a promise returns a new derived promise, it is easily\n * possible to create a chain of promises:\n *\n * ```js\n * promiseB = promiseA.then(function(result) {\n * return result + 1;\n * });\n *\n * // promiseB will be resolved immediately after promiseA is resolved and its value\n * // will be the result of promiseA incremented by 1\n * ```\n *\n * It is possible to create chains of any length and since a promise can be resolved with another\n * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n * the promises at any point in the chain. This makes it possible to implement powerful APIs like\n * $http's response interceptors.\n *\n *\n * # Differences between Kris Kowal's Q and $q\n *\n * There are two main differences:\n *\n * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n * mechanism in angular, which means faster propagation of resolution or rejection into your\n * models and avoiding unnecessary browser repaints, which would result in flickering UI.\n * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n * all the important functionality needed for common async tasks.\n *\n * # Testing\n *\n * ```js\n * it('should simulate promise', inject(function($q, $rootScope) {\n * var deferred = $q.defer();\n * var promise = deferred.promise;\n * var resolvedValue;\n *\n * promise.then(function(value) { resolvedValue = value; });\n * expect(resolvedValue).toBeUndefined();\n *\n * // Simulate resolving of promise\n * deferred.resolve(123);\n * // Note that the 'then' function does not get called synchronously.\n * // This is because we want the promise API to always be async, whether or not\n * // it got called synchronously or asynchronously.\n * expect(resolvedValue).toBeUndefined();\n *\n * // Propagate promise resolution to 'then' functions using $apply().\n * $rootScope.$apply();\n * expect(resolvedValue).toEqual(123);\n * }));\n * ```\n */\nfunction $QProvider() {\n\n this.$get = ['$rootScope', '$exceptionHandler', function($rootScope, $exceptionHandler) {\n return qFactory(function(callback) {\n $rootScope.$evalAsync(callback);\n }, $exceptionHandler);\n }];\n}\n\n\n/**\n * Constructs a promise manager.\n *\n * @param {function(Function)} nextTick Function for executing functions in the next turn.\n * @param {function(...*)} exceptionHandler Function into which unexpected exceptions are passed for\n * debugging purposes.\n * @returns {object} Promise manager.\n */\nfunction qFactory(nextTick, exceptionHandler) {\n\n /**\n * @ngdoc method\n * @name $q#defer\n * @function\n *\n * @description\n * Creates a `Deferred` object which represents a task which will finish in the future.\n *\n * @returns {Deferred} Returns a new instance of deferred.\n */\n var defer = function() {\n var pending = [],\n value, deferred;\n\n deferred = {\n\n resolve: function(val) {\n if (pending) {\n var callbacks = pending;\n pending = undefined;\n value = ref(val);\n\n if (callbacks.length) {\n nextTick(function() {\n var callback;\n for (var i = 0, ii = callbacks.length; i < ii; i++) {\n callback = callbacks[i];\n value.then(callback[0], callback[1], callback[2]);\n }\n });\n }\n }\n },\n\n\n reject: function(reason) {\n deferred.resolve(createInternalRejectedPromise(reason));\n },\n\n\n notify: function(progress) {\n if (pending) {\n var callbacks = pending;\n\n if (pending.length) {\n nextTick(function() {\n var callback;\n for (var i = 0, ii = callbacks.length; i < ii; i++) {\n callback = callbacks[i];\n callback[2](progress);\n }\n });\n }\n }\n },\n\n\n promise: {\n then: function(callback, errback, progressback) {\n var result = defer();\n\n var wrappedCallback = function(value) {\n try {\n result.resolve((isFunction(callback) ?

One example of\n * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer\n * to these contexts as privileged or SCE contexts.\n *\n * As of version 1.2, Angular ships with SCE enabled by default.\n *\n * Note: When enabled (the default), IE8 in quirks mode is not supported. In this mode, IE8 allows\n * one to execute arbitrary javascript by the use of the expression() syntax. Refer\n * to learn more about them.\n * You can ensure your document is in standards mode and not quirks mode by adding ``\n * to the top of your HTML document.\n *\n * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for\n * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.\n *\n * Here's an example of a binding in a privileged context:\n *\n * 
\n *     \n *     
\n *
\n *\n * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE\n * disabled, this application allows the user to render arbitrary HTML into the DIV.\n * In a more realistic example, one may be rendering user comments, blog articles, etc. via\n * bindings. (HTML is just one example of a context where rendering user controlled input creates\n * security vulnerabilities.)\n *\n * For the case of HTML, you might use a library, either on the client side, or on the server side,\n * to sanitize unsafe HTML before binding to the value and rendering it in the document.\n *\n * How would you ensure that every place that used these types of bindings was bound to a value that\n * was sanitized by your library (or returned as safe for rendering by your server?) How can you\n * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some\n * properties/fields and forgot to update the binding to the sanitized value?\n *\n * To be secure by default, you want to ensure that any such bindings are disallowed unless you can\n * determine that something explicitly says it's safe to use a value for binding in that\n * context. You can then audit your code (a simple grep would do) to ensure that this is only done\n * for those values that you can easily tell are safe - because they were received from your server,\n * sanitized by your library, etc. You can organize your codebase to help with this - perhaps\n * allowing only the files in a specific directory to do this. Ensuring that the internal API\n * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.\n *\n * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}\n * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to\n * obtain values that will be accepted by SCE / privileged contexts.\n *\n *\n * ## How does it work?\n *\n * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted\n * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link\n * ng.$sce#parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the\n * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.\n *\n * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link\n * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly\n * simplified):\n *\n * 
\n *   var ngBindHtmlDirective = ['$sce', function($sce) {\n *     return function(scope, element, attr) {\n *       scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {\n *         element.html(value || '');\n *       });\n *     };\n *   }];\n *
\n *\n * ## Impact on loading templates\n *\n * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as\n * `templateUrl`'s specified by {@link guide/directive directives}.\n *\n * By default, Angular only loads templates from the same domain and protocol as the application\n * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl\n * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or\n * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist\n * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.\n *\n * *Please note*:\n * The browser's\n * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)\n * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)\n * policy apply in addition to this and may further restrict whether the template is successfully\n * loaded. This means that without the right CORS policy, loading templates from a different domain\n * won't work on all browsers. Also, loading templates from `file://` URL does not work on some\n * browsers.\n *\n * ## This feels like too much overhead for the developer?\n *\n * It's important to remember that SCE only applies to interpolation expressions.\n *\n * If your expressions are constant literals, they're automatically trusted and you don't need to\n * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.\n * `
implicitly trusted'\">
`) just works.\n *\n * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them\n * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.\n *\n * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load\n * templates in `ng-include` from your application's domain without having to even know about SCE.\n * It blocks loading templates from other domains or loading templates over http from an https\n * served document. You can change these by setting your own custom {@link\n * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link\n * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.\n *\n * This significantly reduces the overhead. It is far easier to pay the small overhead and have an\n * application that's secure and can be audited to verify that with much more ease than bolting\n * security onto an application later.\n *\n * \n * ## What trusted context types are supported?\n *\n * | Context | Notes |\n * |---------------------|----------------|\n * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. |\n * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |\n * | `$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. |\n * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |\n *\n * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} \n *\n * Each element in these arrays must be one of the following:\n *\n * - **'self'**\n * - The special **string**, `'self'`, can be used to match against all URLs of the **same\n * domain** as the application document using the **same protocol**.\n * - **String** (except the special value `'self'`)\n * - The string is matched against the full *normalized / absolute URL* of the resource\n * being tested (substring matches are not good enough.)\n * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters\n * match themselves.\n * - `*`: matches zero or more occurrences of any character other than one of the following 6\n * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use\n * in a whitelist.\n * - `**`: matches zero or more occurrences of *any* character. As such, it's not\n * not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g.\n * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might\n * not have been the intention.) It's usage at the very end of the path is ok. (e.g.\n * http://foo.example.com/templates/**).\n * - **RegExp** (*see caveat below*)\n * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax\n * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to\n * accidentally introduce a bug when one updates a complex expression (imho, all regexes should\n * have good test coverage.). For instance, the use of `.` in the regex is correct only in a\n * small number of cases. A `.` character in the regex used when matching the scheme or a\n * subdomain could be matched against a `:` or literal `.` that was likely not intended. It\n * is highly recommended to use the string patterns and only fall back to regular expressions\n * if they as a last resort.\n * - The regular expression must be an instance of RegExp (i.e. not a string.) It is\n * matched against the **entire** *normalized / absolute URL* of the resource being tested\n * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags\n * present on the RegExp (such as multiline, global, ignoreCase) are ignored.\n * - If you are generating your JavaScript from some other templating engine (not\n * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),\n * remember to escape your regular expression (and be aware that you might need more than\n * one level of escaping depending on your templating engine and the way you interpolated\n * the value.) Do make use of your platform's escaping mechanism as it might be good\n * enough before coding your own. e.g. Ruby has\n * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)\n * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).\n * Javascript lacks a similar built in function for escaping. Take a look at Google\n * Closure library's [goog.string.regExpEscape(s)](\n * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).\n *\n * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.\n *\n * ## Show me an example using SCE.\n *\n * @example\n\n\n

\n *   angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {\n *     // Completely disable SCE.  For demonstration purposes only!\n *     // Do not use in new projects.\n *     $sceProvider.enabled(false);\n *   });\n *

It must return an object that will be accepted by\n * getTrusted() for a compatible contextEnum and return this value.\n *\n * - valueOf(value)\n * For values that were not produced by trustAs(), return them as is. For values that were\n * produced by trustAs(), return the corresponding input value to trustAs. Basically, if\n * trustAs is wrapping the given values into some type, this operation unwraps it when given\n * such a value.\n *\n * - getTrusted(contextEnum, value)\n * This function should return the a value that is safe to use in the context specified by\n * contextEnum or throw and exception otherwise.\n *\n * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be\n * opaque or wrapped in some holder object. That happens to be an implementation detail. For\n * instance, an implementation could maintain a registry of all trusted objects by context. In\n * such a case, trustAs() would return the same object that was passed in. getTrusted() would\n * return the same object passed in if it was found in the registry under a compatible context or\n * throw an exception otherwise. An implementation might only wrap values some of the time based\n * on some criteria. getTrusted() might return a value and not throw an exception for special\n * constants or objects even if not wrapped. All such implementations fulfill this contract.\n *\n *\n * A note on the inheritance model for SCE contexts\n * ------------------------------------------------\n * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This\n * is purely an implementation details.\n *\n * The contract is simply this:\n *\n * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)\n * will also succeed.\n *\n * Inheritance happens to capture this in a natural way.

This approach has wide\n * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See\n * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n *\n * Implementation Notes for IE\n * ---------------------------\n * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other\n * browsers. However, the parsed components will not be set if the URL assigned did not specify\n * them. (e.g. if you assign a.href = \"foo\", then a.protocol, a.host, etc. will be empty.) We\n * work around that by performing the parsing in a 2nd step by taking a previously normalized\n * URL (e.g. by assigning to a.href) and assigning it a.href again.

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

Use this\n * directive to avoid the undesirable flicker effect caused by the html template display.\n *\n * The directive can be applied to the `` element, but the preferred usage is to apply\n * multiple `ngCloak` directives to small portions of the page to permit progressive rendering\n * of the browser view.\n *\n * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and\n * `angular.min.js`.\n * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).\n *\n * ```css\n * [ng\\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {\n *   display: none !important;\n * }\n * ```\n *\n * When this css rule is loaded by the browser, all html elements (including their children) that\n * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive\n * during the compilation of the template it deletes the `ngCloak` element attribute, making\n * the compiled element visible.\n *\n * For the best result, the `angular.js` script must be loaded in the head section of the html\n * document; alternatively, the css rule above must be included in the external stylesheet of the\n * application.\n *\n * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they\n * cannot match the `[ng\\:cloak]` selector. To work around this limitation, you must add the css\n * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.\n *\n * @element ANY\n *\n * @example\n   \n     \n

This is a key aspect of how angular\n * supports the principles behind the Model-View-Controller design pattern.\n *\n * MVC components in angular:\n *\n * * Model — The Model is scope properties; scopes are attached to the DOM where scope properties\n *   are accessed through bindings.\n * * View — The template (HTML with data bindings) that is rendered into the View.\n * * Controller — The `ngController` directive specifies a Controller class; the class contains business\n *   logic behind the application to decorate the scope with functions and values\n *\n * Note that you can also attach controllers to the DOM by declaring it in a route definition\n * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller\n * again using `ng-controller` in the template itself.  This will cause the controller to be attached\n * and executed twice.\n *\n * @element ANY\n * @scope\n * @param {expression} ngController Name of a globally accessible constructor function or an\n *     {@link guide/expression expression} that on the current scope evaluates to a\n *     constructor function. The controller instance can be published into a scope property\n *     by specifying `as propertyName`.\n *\n * @example\n * Here is a simple form for editing user contact information. Adding, removing, clearing, and\n * greeting are methods declared on the controller (see source tab). These methods can\n * easily be called from the angular markup. Notice that the scope becomes the `this` for the\n * controller's instance. This allows for easy access to the view data from the controller. Also\n * notice that any changes to the data are automatically reflected in the View without the need\n * for a manual update. The example is shown in two different declaration styles you may use\n * according to preference.\n   \n     \n      \n

If the expression assigned to `ngIf` evaluates to a false\n * value then the element is removed from the DOM, otherwise a clone of the\n * element is reinserted into the DOM.\n *\n * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the\n * element in the DOM rather than changing its visibility via the `display` css property.  A common\n * case when this difference is significant is when using css selectors that rely on an element's\n * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.\n *\n * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope\n * is created when the element is restored.  The scope created within `ngIf` inherits from\n * its parent scope using\n * [prototypal inheritance](https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance).\n * An important implication of this is if `ngModel` is used within `ngIf` to bind to\n * a javascript primitive defined in the parent scope. In this case any modifications made to the\n * variable within the child scope will override (hide) the value in the parent scope.\n *\n * Also, `ngIf` recreates elements using their compiled state. An example of this behavior\n * is if an element's class attribute is directly modified after it's compiled, using something like\n * jQuery's `.addClass()` method, and the element is later removed.

You configure ngPluralize directive\n * by specifying the mappings between\n * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)\n * and the strings to be displayed.\n *\n * # Plural categories and explicit number rules\n * There are two\n * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)\n * in Angular's default en-US locale: \"one\" and \"other\".\n *\n * While a plural category may match many numbers (for example, in en-US locale, \"other\" can match\n * any number that is not 1), an explicit number rule can only match one number. For example, the\n * explicit number rule for \"3\" matches the number 3. There are examples of plural categories\n * and explicit number rules throughout the rest of this documentation.\n *\n * # Configuring ngPluralize\n * You configure ngPluralize by providing 2 attributes: `count` and `when`.\n * You can also provide an optional attribute, `offset`.\n *\n * The value of the `count` attribute can be either a string or an {@link guide/expression\n * Angular expression}; these are evaluated on the current scope for its bound value.\n *\n * The `when` attribute specifies the mappings between plural categories and the actual\n * string to be displayed. The value of the attribute should be a JSON object.\n *\n * The following example shows how to configure ngPluralize:\n *\n * ```html\n * \n * \n *```\n *\n * In the example, `\"0: Nobody is viewing.\"` is an explicit number rule. If you did not\n * specify this rule, 0 would be matched to the \"other\" category and \"0 people are viewing\"\n * would be shown instead of \"Nobody is viewing\". You can specify an explicit number rule for\n * other numbers, for example 12, so that instead of showing \"12 people are viewing\", you can\n * show \"a dozen people are viewing\".\n *\n * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted\n * into pluralized strings. In the previous example, Angular will replace `{}` with\n * `{{personCount}}`. The closed braces `{}` is a placeholder\n * for {{numberExpression}}.\n *\n * # Configuring ngPluralize with offset\n * The `offset` attribute allows further customization of pluralized text, which can result in\n * a better user experience. For example, instead of the message \"4 people are viewing this document\",\n * you might display \"John, Kate and 2 others are viewing this document\".\n * The offset attribute allows you to offset a number by any desired value.\n * Let's take a look at an example:\n *\n * ```html\n * \n * \n * ```\n *\n * Notice that we are still using two plural categories(one, other), but we added\n * three explicit number rules 0, 1 and 2.\n * When one person, perhaps John, views the document, \"John is viewing\" will be shown.\n * When three people view the document, no explicit number rule is found, so\n * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.\n * In this case, plural category 'one' is matched and \"John, Marry and one other person are viewing\"\n * is shown.\n *\n * Note that when you specify offsets, you must provide explicit number rules for\n * numbers from 0 up to and including the offset. If you use an offset of 3, for example,\n * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for\n * plural categories \"one\" and \"other\".\n *\n * @param {string|expression} count The variable to be bound to.\n * @param {string} when The mapping between plural category to its corresponding strings.\n * @param {number=} offset Offset to deduct from the total number.\n *\n * @example\n    \n      \n        \n        
\n          Person 1:
\n          Person 2:
\n          Number of People:

Each template\n * instance gets its own scope, where the given loop variable is set to the current collection item,\n * and `$index` is set to the item index or key.\n *\n * Special properties are exposed on the local scope of each template instance, including:\n *\n * | Variable  | Type            | Details                                                                     |\n * |-----------|-----------------|-----------------------------------------------------------------------------|\n * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |\n * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |\n * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |\n * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |\n * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |\n * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |\n *\n * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.\n * This may be useful when, for instance, nesting ngRepeats.\n *\n * # Special repeat start and end points\n * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending\n * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.\n * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)\n * up to and including the ending HTML tag where **ng-repeat-end** is placed.\n *\n * The example below makes use of this feature:\n * ```html\n *   
\n *     Header {{ item }}\n *   
\n *   
\n *     Body {{ item }}\n *   
\n *   
\n *     Footer {{ item }}\n *   
\n * ```\n *\n * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:\n * ```html\n *   
\n *     Header A\n *   
\n *   
\n *     Body A\n *   
\n *   
\n *     Footer A\n *   
\n *   
\n *     Header B\n *   
\n *   
\n *     Body B\n *   
\n *   
\n *     Footer B\n *   
\n * ```\n *\n * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such\n * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).\n *\n * @animations\n * **.enter** - when a new item is added to the list or when an item is revealed after a filter\n *\n * **.leave** - when an item is removed from the list or when an item is filtered out\n *\n * **.move** - when an adjacent item is filtered out causing a reorder or when the item contents are reordered\n *\n * @element ANY\n * @scope\n * @priority 1000\n * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These\n *   formats are currently supported:\n *\n *   * `variable in expression` – where variable is the user defined loop variable and `expression`\n *     is a scope expression giving the collection to enumerate.\n *\n *     For example: `album in artist.albums`.\n *\n *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,\n *     and `expression` is the scope expression giving the collection to enumerate.\n *\n *     For example: `(name, age) in {'adam':10, 'amalie':12}`.\n *\n *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function\n *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function\n *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have\n *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are\n *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,\n *     before specifying a tracking expression.\n *\n *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements\n *     will be associated by item identity in the array.\n *\n *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique\n *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements\n *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM\n *     element in the same way in the DOM.\n *\n *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this\n *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`\n *     property is same.\n *\n *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter\n *     to items in conjunction with a tracking expression.\n *\n * @example\n * This example initializes the scope to a list of names and\n * then uses `ngRepeat` to display every person:\n  \n    \n

In other words, you define a container element\n * (where you place the directive), place an expression on the **`on=\"...\"` attribute**\n * (or the **`ng-switch=\"...\"` attribute**), define any inner elements inside of the directive and place\n * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on\n * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default\n * attribute is displayed.\n *\n * 
\n * Be aware that the attribute values to match against cannot be expressions. They are interpreted\n * as literal string values to match against.\n * For example, **`ng-switch-when=\"someVal\"`** will match against the string `\"someVal\"` not against the\n * value of the expression `$scope.someVal`.\n *
