This module integrates an AngularJS application written in pure +-- javascript into a Yesod application. (As of January 2014, there is some experiemental +-- development work on Fay bindings to AngularJS, but unfortunately it is not currently usable.) +-- +-- An AngularJS application consists of several pieces: +-- +-- * Javascript code consisting of controllers, directives, and services attached to Angular +-- modules. The goal of this javascript is to produce a domain specific language extending HTML. +-- 'embedNgModule' uses the static subsite to serve this javascript code, serving a minimized +-- and compressed file during production and serving individual files during development. +-- +-- * Directive Templates. In Angular, directives should be the only components which manipulate the +-- DOM. This can happen in the directive javascript code or through a directive HTML template. +-- 'embedNgModule' supports templates written in Hamlet, converting the Hamlet to HTML at compile +-- time before embedding the HTML into the generated javascript. +-- +-- * The View. In Angular, the view is written in the DSL extending HTML. Normal Yesod +-- Handlers and Widgets work great for the view (so nothing needed from this module). Note that your +-- Yesod Widgets will not have any julius or attached javascript code, the javascript is entirely +-- managed by 'embedNgModule'. +-- +-- * Testing. Angular makes testing (both unit and end-to-end) easy. For unit and mid-level +-- testing, the normal Angular test runner is the best. +-- 'hamletTestTemplate' assists with integrating Hamlet directive templates into karma. +-- For end2end testing, the "Test.WebDriver.Commands.Angular" module in the +-- package works well. +-- +-- There is an +-- +-- in the source code which shows an application, unit testing with karma, and end2end +-- testing with webdriver. +module Yesod.EmbeddedStatic.AngularJavascript( + -- * File Layout + -- $filelayout + + -- ** Javascript + -- $jsformat + + -- ** Directives + -- $dirformat + + -- * Generators + embedNgModule + , embedNgModules + + -- * Custom Directive Template Processing + , embedNgModuleWithoutTemplates + , embedNgModulesWithoutTemplates + , directiveTemplates + , directiveTemplatesWithSettings + , directiveWidget + + -- * Testing + , hamletTestTemplate +) where + +import Control.Applicative +import Control.Monad (forM, unless) +import Data.Aeson (encode, decode, toJSON, Value) +import Data.Default (def) +import Data.List (isPrefixOf, sort) +import Data.Monoid ((<>), mconcat) +import Language.Haskell.TH +import Network.Mime (MimeType) +import System.Directory (getDirectoryContents, doesDirectoryExist, doesFileExist) +import System.FilePath +import Text.Blaze.Renderer.Text (renderMarkup) +import Text.Julius +import Text.Hamlet (HamletSettings, defaultHamletSettings, shamletFile) +import Text.Hamlet.RT (parseHamletRT, renderHamletRT) +import Yesod.Core.Widget (whamletFileWithSettings, WidgetT, whamlet) +import Yesod.EmbeddedStatic.Generators +import Yesod.EmbeddedStatic.Types +import Yesod.EmbeddedStatic.AngularJsMangle + +import qualified Data.ByteString.Lazy as BL +import qualified Data.Text as T +import qualified Data.Text.Lazy as TL +import qualified Data.Text.Lazy.IO as TL +import qualified Data.Text.Lazy.Encoding as TL + +------------------------------------------------------------------------------- +-- Generator +------------------------------------------------------------------------------- + +loadModule :: FilePath -> IO ([FilePath], [FilePath], Value) -- (javascript files, hamlet files, module dependency) +loadModule dir = do + content <- getDirectoryContents dir + let files = sort $ filter (\m -> takeExtension m == ".js") content + let tmpls = sort $ filter (\m -> takeExtension m == ".hamlet") content + + deps <- if "module-deps.json" `elem` content + then do ct <- BL.readFile $ dir "module-deps.json" + case decode ct of + Just x -> return x + Nothing -> return $ toJSON ([] :: [String]) + else return $ toJSON ([] :: [String]) + + return (files, tmpls, deps) + +procTemplate :: FilePath -> IO (String, TL.Text) +procTemplate f = do + ct <- TL.readFile f + ham <- parseHamletRT defaultHamletSettings $ TL.unpack ct + html <- renderHamletRT ham [] (\() _ -> error "No url allowed") + + let jsF = replaceExtension f ".js" + e <- doesFileExist jsF + unless e $ error $ "Unable to find " ++ jsF + mid <- parseDirectiveFile jsF + name <- case mid of + Nothing -> error $ "Unable to find templateUrl in " ++ jsF + Just (x, _) -> return x + + return (name, renderMarkup html) + +toCache :: [(String, TL.Text)] -> BL.ByteString +toCache [] = BL.empty +toCache ts = BL.concat $ [header] ++ concatMap go ts ++ [footer] + where + header = "module.run(['$templateCache', function($templateCache) {\n" + footer = "}]);\n" + go (name, html) = [ "$templateCache.put(" + , encode name + , "," + , encode html + , ");\n" + ] + +productionModule :: Bool -> String -> FilePath -> (BL.ByteString -> IO BL.ByteString) -> IO BL.ByteString +productionModule inclTempl name dir mini = do + putStrLn $ "Building AngularJS module " ++ name ++ " (" ++ dir ++ ")" + (files, tmpls, deps) <- loadModule dir + ct <- mapM cleanupDIFile $ map (dir) files + tCt <- if inclTempl + then toCache <$> mapM procTemplate (map (dir) tmpls) + else return BL.empty + let fileCt = "(function(module) {" + <> BL.concat ct + <> tCt + <> "})(angular.module(" + <> encode name + <> "," + <> encode deps + <> "));" + mini fileCt + +develModule :: Bool -> String -> FilePath -> IO BL.ByteString +develModule inclTempl name dir = do + (jsFiles, tmpls, deps) <- loadModule dir + let files = if inclTempl then jsFiles ++ tmpls else jsFiles + + let script = [julius| +(function() { + /* We want to defer bootstrap until all scripts are loaded */ + if (!/^NG_DEFER_BOOTSTRAP!/.test(window.name)) { + window.name = "NG_DEFER_BOOTSTRAP!" + window.name;

This can be used to clean up any 3rd party bindings to the DOM + * element before it is removed. + * + * ### Methods + * - `controller(name)` - retrieves the controller of the current element or its parent. By default + * retrieves controller associated with the `ngController` directive. If `name` is provided as + * camelCase directive name, then the controller for this directive will be retrieved (e.g. + * `'ngModel'`). + * - `injector()` - retrieves the injector of the current element or its parent. + * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current + * element or its parent. + * - `isolateScope()` - retrieves an isolate {@link api/ng.$rootScope.Scope scope} if one is attached directly to the + * current element. This getter should be used only on elements that contain a directive which starts a new isolate + * scope. Calling `scope()` on this element always returns the original non-isolate scope. + * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top + * parent element is reached. + * + * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. + * @returns {Object} jQuery object. + */ + +var jqCache = JQLite.cache = {}, + jqName = JQLite.expando = 'ng-' + new Date().getTime(), + jqId = 1, + addEventListenerFn = (window.document.addEventListener + ? function(element, type, fn) {element.addEventListener(type, fn, false);} + : function(element, type, fn) {element.attachEvent('on' + type, fn);}), + removeEventListenerFn = (window.document.removeEventListener + ? function(element, type, fn) {element.removeEventListener(type, fn, false); } + : function(element, type, fn) {element.detachEvent('on' + type, fn); }); + +function jqNextId() { return ++jqId; } + + +var SPECIAL_CHARS_REGEXP = /([\:\-\_]+(.))/g; +var MOZ_HACK_REGEXP = /^moz([A-Z])/; +var jqLiteMinErr = minErr('jqLite'); + +/** + * Converts snake_case to camelCase. + * Also there is special case for Moz prefix starting with upper case letter. + * @param name Name to normalize + */ +function camelCase(name) { + return name. + replace(SPECIAL_CHARS_REGEXP, function(_, separator, letter, offset) { + return offset ? letter.toUpperCase() : letter; + }). + replace(MOZ_HACK_REGEXP, 'Moz$1'); +} + +///////////////////////////////////////////// +// jQuery mutation patch +// +// In conjunction with bindJQuery intercepts all jQuery's DOM destruction apis and fires a +// $destroy event on all DOM nodes being removed. +// +///////////////////////////////////////////// + +function jqLitePatchJQueryRemove(name, dispatchThis, filterElems, getterIfNoArguments) { + var originalJqFn = jQuery.fn[name]; + originalJqFn = originalJqFn.$original || originalJqFn; + removePatch.$original = originalJqFn; + jQuery.fn[name] = removePatch; + + function removePatch(param) { + // jshint -W040 + var list = filterElems && param ?

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

While for simple usage patterns this doesn't matter much, for advanced usage + * it is important to familiarize yourself with these APIs and the guarantees they provide. + * + * + * # General usage + * The `$http` service is a function which takes a single argument — a configuration object — + * that is used to generate an HTTP request and returns a {@link ng.$q promise} + * with two $http specific methods: `success` and `error`. + * + * 
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }).
+     *     error(function(data, status, headers, config) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     *
+ * + * Since the returned value of calling the $http function is a `promise`, you can also use + * the `then` method to register callbacks, and these callbacks will receive a single argument – + * an object representing the response. See the API signature and type info below for more + * details. + * + * A response status code between 200 and 299 is considered a success status and + * will result in the success callback being called. Note that if the response is a redirect, + * XMLHttpRequest will transparently follow it, meaning that the error callback will not be + * called for such responses. + * + * # Calling $http from outside AngularJS + * The `$http` service will not actually send the request until the next `$digest()` is + * executed. Normally this is not an issue, since almost all the time your call to `$http` will + * be from within a `$apply()` block. + * If you are calling `$http` from outside Angular, then you should wrap it in a call to + * `$apply` to cause a $digest to occur and also to handle errors in the block correctly. + * + * ``` + * $scope.$apply(function() { + * $http(...); + * }); + * ``` + * + * # Writing Unit Tests that use $http + * When unit testing you are mostly responsible for scheduling the `$digest` cycle. If you do + * not trigger a `$digest` before calling `$httpBackend.flush()` then the request will not have + * been made and `$httpBackend.expect(...)` expectations will fail. The solution is to run the + * code that calls the `$http()` method inside a $apply block as explained in the previous + * section. + * + * ``` + * $httpBackend.expectGET(...); + * $scope.$apply(function() { + * $http.get(...); + * }); + * $httpBackend.flush(); + * ``` + * + * # Shortcut methods + * + * Since all invocations of the $http service require passing in an HTTP method and URL, and + * POST/PUT requests require request data to be provided as well, shortcut methods + * were created: + * + * 
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     *
+ * + * Complete list of shortcut methods: + * + * - {@link ng.$http#methods_get $http.get} + * - {@link ng.$http#methods_head $http.head} + * - {@link ng.$http#methods_post $http.post} + * - {@link ng.$http#methods_put $http.put} + * - {@link ng.$http#methods_delete $http.delete} + * - {@link ng.$http#methods_jsonp $http.jsonp} + * + * + * # Setting HTTP Headers + * + * The $http service will automatically add certain HTTP headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * + * # Transforming Requests and Responses + * + * Both requests and responses can be transformed using transform functions. By default, Angular + * applies these transformations: + * + * Request transformations: + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations: + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If JSON response is detected, deserialize it using a JSON parser. + * + * To globally augment or override the default transforms, modify the + * `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse` + * properties. These properties are by default an array of transform functions, which allows you + * to `push` or `unshift` a new transformation function into the transformation chain. You can + * also decide to completely override any default transformations by assigning your + * transformation functions to these properties directly without the array wrapper. + * + * Similarly, to locally override the request/response transforms, augment the + * `transformRequest` and/or `transformResponse` properties of the configuration object passed + * into `$http`. + * + * + * # Caching + * + * To enable caching, set the request configuration `cache` property to `true` (to use default + * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}). + * When the cache is enabled, `$http` stores the response from the server in the specified + * cache. The next time the same request is made, the response is served from the cache without + * sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same URL that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response from the first request. + * + * You can change the default cache to a new object (built with + * {@link ng.$cacheFactory `$cacheFactory`}) by updating the + * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set + * their `cache` property to `true` will now use this cache object. + * + * If you set the default cache to `false` then only requests that specify their own custom + * cache object will be cached. + * + * # Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests.

+ * + * + * # Security Considerations + * + * When designing web applications, consider security threats from: + * + * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON vulnerability} + * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} + * + * Both server and the client must cooperate in order to eliminate these threats. Angular comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ## JSON Vulnerability Protection + * + * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx + * JSON vulnerability} allows third party website to turn your JSON resource URL into + * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * Angular will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * 
+     * ['one','two']
+     *
+ * + * which is vulnerable to attack, your server can return: + * 
+     * )]}',
+     * ['one','two']
+     *
+ * + * Angular will strip the prefix, before processing the JSON. + * + * + * ## Cross Site Request Forgery (XSRF) Protection + * + * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which + * an unauthorized site can gain your user's private data. Angular provides a mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only + * JavaScript that runs on your domain could read the cookie, your server can be assured that + * the XHR came from JavaScript running on your domain. The header will not be set for + * cross-domain requests. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure + * that only JavaScript running on your domain could have sent the request. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt} + * for added security. + * + * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName + * properties of either $httpProvider.defaults, or the per-request config object. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. + * - **params** – `{Object.}` – Map of strings or objects which will be turned + * to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be + * JSONified. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server. If the return value of a function is null, the + * header will not be sent. + * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. + * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. + * - **transformRequest** – + * `{function(data, headersGetter)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * request body and headers and returns its transformed (typically serialized) version. + * - **transformResponse** – + * `{function(data, headersGetter)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * response body and headers and returns its transformed (typically deserialized) version. + * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the + * GET request, otherwise if a cache instance built with + * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} + * that should abort the request when resolved. + * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the + * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 + * requests with credentials} for more information. + * - **responseType** - `{string}` - see {@link + * https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}. + * + * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the + * standard `then` method and two http specific methods: `success` and `error`. The `then` + * method takes two arguments a success and an error callback which will be called with a + * response object. The `success` and `error` methods take a single argument - a function that + * will be called when the request succeeds or fails respectively. The arguments passed into + * these functions are destructured representation of the response object passed into the + * `then` method. The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with the transform + * functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used to generate the request. + * + * @property {Array.} pendingRequests Array of config objects for currently pending + * requests.

+ * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * + * # The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promises execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * # The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback`. It also notifies via the return value of the + * `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback + * method. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as + * property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to + * make your code IE8 compatible. + * + * # Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * 
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ *
+ * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * # Differences between Kris Kowal's Q and $q + * + * There are three main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in angular, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * # Testing + * + *

(Since `watchExpression` + * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a + * change is detected, be prepared for multiple calls to your listener.) + * + * After a watcher is registered with the scope, the `listener` fn is called asynchronously + * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the + * watcher. In rare cases, this is undesirable because the listener is called when the result + * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you + * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the + * listener was called due to initialization. + * + * The example below contains an illustration of using a function as your $watch listener + * + * + * # Example + *

One example of + * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer + * to these contexts as privileged or SCE contexts. + * + * As of version 1.2, Angular ships with SCE enabled by default. + * + * Note: When enabled (the default), IE8 in quirks mode is not supported. In this mode, IE8 allows + * one to execute arbitrary javascript by the use of the expression() syntax. Refer + * to learn more about them. + * You can ensure your document is in standards mode and not quirks mode by adding `` + * to the top of your HTML document. + * + * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for + * security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * Here's an example of a binding in a privileged context: + * + * 
+ *     
+ *     

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

This approach has wide + * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See + * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html + * + * Implementation Notes for IE + * --------------------------- + * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other + * browsers. However, the parsed components will not be set if the URL assigned did not specify + * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We + * work around that by performing the parsing in a 2nd step by taking a previously normalized + * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the + * properties such as protocol, hostname, port, etc. + * + * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one + * uses the inner HTML approach to assign the URL as part of an HTML snippet - + * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL. + * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception. + * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that + * method and IE < 8 is unsupported. + * + * References: + * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement + * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html + * http://url.spec.whatwg.org/#urlutils + * https://github.com/angular/angular.js/pull/2902 + * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/ + * + * @function + * @param {string} url The URL to be parsed. + * @description Normalizes and parses a URL. + * @returns {object} Returns the normalized URL as a dictionary. + * + * | member name | Description | + * |---------------|----------------| + * | href | A normalized version of the provided URL if it was not an absolute URL | + * | protocol | The protocol including the trailing colon | + * | host | The host and port (if the port is non-default) of the normalizedUrl | + * | search | The search params, minus the question mark | + * | hash | The hash string, minus the hash symbol + * | hostname | The hostname + * | port | The port, without ":" + * | pathname | The pathname, beginning with "/" + * + */ +function urlResolve(url, base) { + var href = url; + + if (msie) { + // Normalize before parse.

+   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 ngAnimate.$animate#methods_addclass $animate.addClass} and
+   {@link ngAnimate.$animate#methods_removeclass $animate.removeClass}.

+ * @ngdoc directive
+ * @name ng.directive:ngCloak
+ * @restrict AC
+ *
+ * @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 `` 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.
+ *
+ * `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}).
+ *
+ * 
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * 

+ *
+ * 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.
+ *
+ * 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 `ngCloak` in addition to the `ngCloak` directive as shown in the example below.
+ *
+ * @element ANY
+ *

+ * @ngdoc directive
+ * @name ng.directive:ngController
+ *
+ * @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.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is scope properties; 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.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ngController Name of a globally accessible constructor function or an
+ *     {@link guide/expression expression} that on the current scope evaluates to a
+ *     constructor function. The controller instance can be published into a scope property
+ *     by specifying `as propertyName`.
+ *
+ * @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. Notice that the scope becomes the `this` for the
+ * controller's instance. This allows for easy access to the view data from the controller. Also
+ * notice that any changes to the data are automatically reflected in the View without the need
+ * for a manual update. The example is shown in two different declaration styles you may use
+ * according to preference.

+ * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
+ *
+ * This is necessary when developing things like Google Chrome Extensions.
+ *
+ * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
+ * For us to be compatible, we just need to implement the "getterFn" in $parse without violating
+ * any of these restrictions.
+ *
+ * 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.
+ *
+ * In order to use this feature put the `ngCsp` directive on the root element of the application.
+ *
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ *
+ * @example
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.

+ * @ngdoc directive

+ * @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
+ * {@link https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance 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

+ * @ngdoc directive
+ * @name ng.directive:ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * 
+ * 
+ * 
+ *

+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * `{{personCount}}`. The closed braces `{}` is a placeholder
+ * for {{numberExpression}}.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * 
+ * 
+ * 
+ * 

+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its corresponding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example
+    
+      
+        
+        

+          Person 1:

+          Person 2:

+          Number of People:

+
+          
+          Without Offset:
+          
+          

+
+          
+          With Offset(2):

+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ * | Variable  | Type            | Details                                                                     |
+ * |-----------|-----------------|-----------------------------------------------------------------------------|
+ * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+ * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+ * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+ * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+ * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+ *
+ *
+ * # 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.
+ * 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)
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+ *
+ * The example below makes use of this feature:
+ * 
+ *   

+ *     Header {{ item }}
+ *   

+ *   

+ *     Body {{ item }}
+ *   

+ *   

+ *     Footer {{ item }}
+ *   

+ * 

+ *
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+ * 
+ *   

+ *     Header A
+ *   

+ *   

+ *     Body A
+ *   

+ *   

+ *     Footer A
+ *   

+ *   

+ *     Header B
+ *   

+ *   

+ *     Body B
+ *   

+ *   

+ *     Footer B
+ *

+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
+ *
+ * @animations
+ * enter - when a new item is added to the list or when an item is revealed after a filter
+ * leave - when an item is removed from the list or when an item is filtered out
+ * move - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `album in artist.albums`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
+ *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function
+ *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have
+ *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
+ *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,
+ *     before specifying a tracking expression.
+ *
+ *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements
+ *     will be associated by item identity in the array.
+ *
+ *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
+ *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
+ *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
+ *     element in the same way in the DOM.
+ *
+ *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
+ *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
+ *     property is same.
+ *
+ *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
+ *     to items in conjunction with a tracking expression.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ngRepeat` to display every person:

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngShow
+ *
+ * @description
+ * The `ngShow` directive shows or hides the given HTML element based on the expression
+ * provided to the ngShow attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * 
+ * 
+ * 

+ *
+ * 
+ * 

+ * 

+ *
+ * When the ngShow expression evaluates to false then the ng-hide CSS class is added to the class attribute
+ * on the element causing it to become hidden. When true, the ng-hide CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding .ng-hide
+ *
+ * If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
+ * restating the styles for the .ng-hide class in CSS:
+ * 
+ * .ng-hide {
+ *   //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
+ *   display:block!important;
+ *
+ *   //this is just another form of hiding an element
+ *   position:absolute;
+ *   top:-9999px;
+ *   left:-9999px;
+ * }
+ * 

+ *
+ * Just remember to include the important flag so the CSS override will function.
+ *
+ * ## A note about animations with ngShow
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass except that
+ * you must also include the !important flag to override the display property
+ * so that you can perform an animation when the element is hidden during the time of the animation.
+ *
+ * 
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ *   transition:0.5s linear all;
+ *   display:block!important;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * 

+ *
+ * @animations
+ * addClass: .ng-hide - happens after the ngShow expression evaluates to a truthy value and the just before contents are set to visible
+ * removeClass: .ng-hide - happens after the ngShow expression evaluates to a non truthy value and just before the contents are set to hidden
+ *
+ * @element ANY
+ * @param {expression} ngShow If the {@link guide/expression expression} is truthy
+ *     then the element is shown or hidden respectively.

+ * The `ngHide` directive shows or hides the given HTML element based on the expression
+ * provided to the ngHide attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * 
+ * 
+ * 

+ *
+ * 
+ * 

+ * 

+ *
+ * When the ngHide expression evaluates to true then the .ng-hide CSS class is added to the class attribute
+ * on the element causing it to become hidden. When false, the ng-hide CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding .ng-hide
+ *
+ * If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
+ * restating the styles for the .ng-hide class in CSS:
+ * 
+ * .ng-hide {
+ *   //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
+ *   display:block!important;
+ *
+ *   //this is just another form of hiding an element
+ *   position:absolute;
+ *   top:-9999px;
+ *   left:-9999px;
+ * }
+ * 

+ *
+ * Just remember to include the important flag so the CSS override will function.
+ *
+ * ## A note about animations with ngHide
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass, except that
+ * you must also include the !important flag to override the display property so
+ * that you can perform an animation when the element is hidden during the time of the animation.
+ *
+ * 
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ *   transition:0.5s linear all;
+ *   display:block!important;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * 

+ *
+ * @animations
+ * removeClass: .ng-hide - happens after the ngHide expression evaluates to a truthy value and just before the contents are set to hidden
+ * addClass: .ng-hide - happens after the ngHide expression evaluates to a non truthy value and just before the contents are set to visible
+ *
+ * @element ANY
+ * @param {expression} ngHide If the {@link guide/expression expression} is truthy then
+ *     the element is shown or hidden respectively.
+ *
+ * @example
+  
+    
+      Click me: 

+

+ * @description
+ * The ngSwitch directive is used to conditionally swap DOM structure on your template based on a scope expression.
+ * Elements within ngSwitch but without ngSwitchWhen or ngSwitchDefault directives will be preserved at the location
+ * as specified in the template.
+ *
+ * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+ * from the template cache), ngSwitch simply choses one of the nested elements and makes it visible based on which element
+ * matches the value obtained from the evaluated expression. In other words, you define a container element
+ * (where you place the directive), place an expression on the **on="..." attribute**
+ * (or the **ng-switch="..." attribute**), define any inner elements inside of the directive and place
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+ * attribute is displayed.
+ *
+ * @animations
+ * enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
+ * leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM
+ *

+ *

+ * @scope

+ * @param {*} ngSwitch|on expression to match against ng-switch-when.
+ * @paramDescription
+ * On child elements add:
+ *
+ * * `ngSwitchWhen`: the case statement to match against. If match then this
+ *   case will be displayed. If the same match appears multiple times, all the
+ *   elements will be displayed.
+ * * `ngSwitchDefault`: the default case when no other case match. If there
+ *   are multiple default cases, all of them will be displayed when no other
+ *   case match.
