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, * / *` + * - `X-Requested-With: XMLHttpRequest` + * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from this configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with name equal to the lower-cased http method name, e.g. + * `$httpProvider.defaults.headers.get['My-Header']='value'`. + * + * Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar + * fassion as described above. + * + * + * # 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 config 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 override these transformation locally, specify transform functions as `transformRequest` + * and/or `transformResponse` properties of the config object. To globally override the default + * transforms, override the `$httpProvider.defaults.transformRequest` and + * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`. + * + * + * # Caching + * + * To enable caching set the configuration property `cache` to `true`. When the cache is + * enabled, `$http` stores the response from the server in local cache. Next time 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 for the first request. + * + * + * # Response interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication or any kind of synchronous or + * asynchronous preprocessing of received responses, it is desirable to be able to intercept + * responses for http requests before they are handed over to the application code that + * initiated these requests. The response interceptors leverage the {@link ng.$q + * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. + * + * The interceptors are service factories that are registered with the $httpProvider by + * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor — a function that + * takes a {@link ng.$q promise} and returns the original or a new promise. + * + * <pre> + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return function(promise) { + * return promise.then(function(response) { + * // do something on success + * }, function(response) { + * // do something on error + * if (canRecover(response)) { + * return responseOrNewPromise + * } + * return $q.reject(response); + * }); + * } + * }); + * + * $httpProvider.responseInterceptors.push('myHttpInterceptor'); + * + * + * // register the interceptor via an anonymous factory + * $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) { + * return function(promise) { + * // same as above + * } + * }); + * </pre> + * + * + * # Security Considerations + * + * When designing web applications, consider security threats from: + * + * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability... + * 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... + * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into + * {@link http://en.wikipedia.org/wiki/JSON#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: + * <pre> + * ['one','two'] + * </pre> + * + * which is vulnerable to attack, your server can return: + * <pre> + * )]}', + * ['one','two'] + * </pre> + * + * 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 following mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * called `XSRF-TOKEN` and sets it as the 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. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET 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 read the token. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript making + * up its own tokens). We recommend that the token is a digest of your site's authentication + * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. + * + * + * @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.<string|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 representing HTTP headers to send to the server. + * - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – + * 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.<function(data, headersGetter)>}` – + * 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 $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number}` – timeout in milliseconds. + * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the + * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 + * requests with credentials} for more information. + * - **responseType** - `{string}` - see {@link + * https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}. + * + * @returns {HttpPromise} Returns a {@link ng.$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.<Object>} pendingRequests Array of config objects for currently pending + * requests.

You configure ngPluralize directive + * by specifying the mappings between + * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_ru... + * 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_ru... + * plural categories} in Angular's default en-US locale: "one" and "other". + * + * While a pural 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. You will see the use of plural categories + * and explicit number rules throughout later parts 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 so that Angular + * can interpret it correctly. + * + * The following example shows how to configure ngPluralize: + * + * <pre> + * <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + * 'one': '1 person is viewing.', + * 'other': '{} people are viewing.'}"> + * </ng-pluralize> + *</pre> + * + * 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 + * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder + * for <span ng-non-bindable>{{numberExpression}}</span>. + * + * # 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: + * + * <pre> + * <ng-pluralize count="personCount" offset=2 + * when="{'0': 'Nobody is viewing.', + * '1': '{{person1}} is viewing.', + * '2': '{{person1}} and {{person2}} are viewing.', + * 'one': '{{person1}}, {{person2}} and one other person are viewing.', + * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + * </ng-pluralize> + * </pre> + * + * 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 correspoding strings. + * @param {number=} offset Offset to deduct from the total number. + * + * @example + doc:example + doc:source + <script> + function Ctrl($scope) { + $scope.person1 = 'Igor'; + $scope.person2 = 'Misko'; + $scope.personCount = 1; + } + </script> + <div ng-controller="Ctrl"> + Person 1:<input type="text" ng-model="person1" value="Igor" /><br/> + Person 2:<input type="text" ng-model="person2" value="Misko" /><br/> + Number of People:<input type="text" ng-model="personCount" value="1" /><br/> + + <!--- Example with simple pluralization rules for en locale ---> + Without Offset: + <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + 'one': '1 person is viewing.', + 'other': '{} people are viewing.'}"> + </ng-pluralize><br> + + <!--- Example with offset ---> + With Offset(2): + <ng-pluralize count="personCount" offset=2 + when="{'0': 'Nobody is viewing.', + '1': '{{person1}} is viewing.', + '2': '{{person1}} and {{person2}} are viewing.', + 'one': '{{person1}}, {{person2}} and one other person are viewing.', + 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + </ng-pluralize> + </div> + </doc:source> + doc:scenario + it('should show correct pluralized string', function() { + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('1 person is viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor is viewing.'); + + using('.doc-example-live').input('personCount').enter('0'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('Nobody is viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Nobody is viewing.'); + + using('.doc-example-live').input('personCount').enter('2'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('2 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor and Misko are viewing.'); + + using('.doc-example-live').input('personCount').enter('3'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('3 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and one other person are viewing.'); + + using('.doc-example-live').input('personCount').enter('4'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('4 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and 2 other people are viewing.'); + }); + + it('should show data-binded names', function() { + using('.doc-example-live').input('personCount').enter('4'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and 2 other people are viewing.'); + + using('.doc-example-live').input('person1').enter('Di'); + using('.doc-example-live').input('person2').enter('Vojta'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Di, Vojta and 2 other people are viewing.'); + }); + </doc:scenario> + </doc:example> + */ +var ngPluralizeDirective = ['$locale', '$interpolate', function($locale, $interpolate) { + var BRACE = /{}/g; + return { + restrict: 'EA', + link: function(scope, element, attr) { + var numberExp = attr.count, + whenExp = element.attr(attr.$attr.when), // this is because we have {{}} in attrs + offset = attr.offset || 0, + whens = scope.$eval(whenExp), + whensExpFns = {}, + startSymbol = $interpolate.startSymbol(), + endSymbol = $interpolate.endSymbol(); + + forEach(whens, function(expression, key) { + whensExpFns[key] = + $interpolate(expression.replace(BRACE, startSymbol + numberExp + '-' + + offset + endSymbol)); + }); + + scope.$watch(function() { + var value = parseFloat(scope.$eval(numberExp)); + + if (!isNaN(value)) { + //if explicit number rule such as 1, 2, 3... is defined, just use it.

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`.

While for simple usage patters this doesn't matter much, for advanced usage, + * it is important to familiarize yourself with these apis and 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`. + * + * <pre> + * $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 status + * // code outside of the <200, 400) range + * }); + * </pre> + * + * Since the returned value of calling the $http function is a Promise object, 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. + * + * + * # Shortcut methods + * + * Since all invocation of the $http service require definition of the http method and url and + * POST and PUT requests require response body/data to be provided as well, shortcut methods + * were created to simplify using the api: + * + * <pre> + * $http.get('/someUrl').success(successCallback); + * $http.post('/someUrl', data).success(successCallback); + * </pre> + * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * + * + * # Setting HTTP Headers + * + * The $http service will automatically add certain http headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `X-Requested-With: XMLHttpRequest` + * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from this configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with name equal to the lower-cased http method name, e.g. + * `$httpProvider.defaults.headers.get['My-Header']='value'`. + * + * Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar + * fassion as described above. + * + * + * # Transforming Requests and Responses + * + * Both requests and responses can be transformed using transform functions. By default, Angular + * applies these transformations: + * + * Request transformations: + * + * - if the `data` property of the request config object contains an object, serialize it into + * JSON format. + * + * Response transformations: + * + * - if XSRF prefix is detected, strip it (see Security Considerations section below) + * - if json response is detected, deserialize it using a JSON parser + * + * To override these transformation locally, specify transform functions as `transformRequest` + * and/or `transformResponse` properties of the config object. To globally override the default + * transforms, override the `$httpProvider.defaults.transformRequest` and + * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`. + * + * + * # Caching + * + * To enable caching set the configuration property `cache` to `true`. When the cache is + * enabled, `$http` stores the response from the server in local cache. Next time the + * response is served from the cache without sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same url that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response for the first request. + * + * + * # Response interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication or any kind of synchronous or + * asynchronous preprocessing of received responses, it is desirable to be able to intercept + * responses for http requests before they are handed over to the application code that + * initiated these requests. The response interceptors leverage the {@link ng.$q + * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. + * + * The interceptors are service factories that are registered with the $httpProvider by + * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor — a function that + * takes a {@link ng.$q promise} and returns the original or a new promise. + * + * <pre> + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return function(promise) { + * return promise.then(function(response) { + * // do something on success + * }, function(response) { + * // do something on error + * if (canRecover(response)) { + * return responseOrNewPromise + * } + * return $q.reject(response); + * }); + * } + * }); + * + * $httpProvider.responseInterceptors.push('myHttpInterceptor'); + * + * + * // register the interceptor via an anonymous factory + * $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) { + * return function(promise) { + * // same as above + * } + * }); + * </pre> + * + * + * # Security Considerations + * + * When designing web applications, consider security threats from: + * + * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability... + * 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... + * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into + * {@link http://en.wikipedia.org/wiki/JSON#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: + * <pre> + * ['one','two'] + * </pre> + * + * which is vulnerable to attack, your server can return: + * <pre> + * )]}', + * ['one','two'] + * </pre> + * + * 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 following mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * called `XSRF-TOKEN` and sets it as the 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. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET 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 read the token. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript making + * up its own tokens). We recommend that the token is a digest of your site's authentication + * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. + * + * + * @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.<string|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 representing HTTP headers to send to the server. + * - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – + * 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.<function(data, headersGetter)>}` – + * 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 $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number}` – timeout in milliseconds. + * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the + * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 + * requests with credentials} for more information. + * - **responseType** - `{string}` - see {@link + * https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}. + * + * @returns {HttpPromise} Returns a {@link ng.$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.<Object>} pendingRequests Array of config objects for currently pending + * requests.

You configure ngPluralize directive + * by specifying the mappings between + * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_ru... + * 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_ru... + * plural categories} in Angular's default en-US locale: "one" and "other". + * + * While a pural 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. You will see the use of plural categories + * and explicit number rules throughout later parts 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 so that Angular + * can interpret it correctly. + * + * The following example shows how to configure ngPluralize: + * + * <pre> + * <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + * 'one': '1 person is viewing.', + * 'other': '{} people are viewing.'}"> + * </ng-pluralize> + *</pre> + * + * 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 + * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder + * for <span ng-non-bindable>{{numberExpression}}</span>. + * + * # 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: + * + * <pre> + * <ng-pluralize count="personCount" offset=2 + * when="{'0': 'Nobody is viewing.', + * '1': '{{person1}} is viewing.', + * '2': '{{person1}} and {{person2}} are viewing.', + * 'one': '{{person1}}, {{person2}} and one other person are viewing.', + * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + * </ng-pluralize> + * </pre> + * + * 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 correspoding strings. + * @param {number=} offset Offset to deduct from the total number. + * + * @example + doc:example + doc:source + <script> + function Ctrl($scope) { + $scope.person1 = 'Igor'; + $scope.person2 = 'Misko'; + $scope.personCount = 1; + } + </script> + <div ng-controller="Ctrl"> + Person 1:<input type="text" ng-model="person1" value="Igor" /><br/> + Person 2:<input type="text" ng-model="person2" value="Misko" /><br/> + Number of People:<input type="text" ng-model="personCount" value="1" /><br/> + + <!--- Example with simple pluralization rules for en locale ---> + Without Offset: + <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + 'one': '1 person is viewing.', + 'other': '{} people are viewing.'}"> + </ng-pluralize><br> + + <!--- Example with offset ---> + With Offset(2): + <ng-pluralize count="personCount" offset=2 + when="{'0': 'Nobody is viewing.', + '1': '{{person1}} is viewing.', + '2': '{{person1}} and {{person2}} are viewing.', + 'one': '{{person1}}, {{person2}} and one other person are viewing.', + 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + </ng-pluralize> + </div> + </doc:source> + doc:scenario + it('should show correct pluralized string', function() { + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('1 person is viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor is viewing.'); + + using('.doc-example-live').input('personCount').enter('0'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('Nobody is viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Nobody is viewing.'); + + using('.doc-example-live').input('personCount').enter('2'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('2 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor and Misko are viewing.'); + + using('.doc-example-live').input('personCount').enter('3'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('3 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and one other person are viewing.'); + + using('.doc-example-live').input('personCount').enter('4'); + expect(element('.doc-example-live ng-pluralize:first').text()). + toBe('4 people are viewing.'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and 2 other people are viewing.'); + }); + + it('should show data-binded names', function() { + using('.doc-example-live').input('personCount').enter('4'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Igor, Misko and 2 other people are viewing.'); + + using('.doc-example-live').input('person1').enter('Di'); + using('.doc-example-live').input('person2').enter('Vojta'); + expect(element('.doc-example-live ng-pluralize:last').text()). + toBe('Di, Vojta and 2 other people are viewing.'); + }); + </doc:scenario> + </doc:example> + */ +var ngPluralizeDirective = ['$locale', '$interpolate', function($locale, $interpolate) { + var BRACE = /{}/g; + return { + restrict: 'EA', + link: function(scope, element, attr) { + var numberExp = attr.count, + whenExp = element.attr(attr.$attr.when), // this is because we have {{}} in attrs + offset = attr.offset || 0, + whens = scope.$eval(whenExp), + whensExpFns = {}, + startSymbol = $interpolate.startSymbol(), + endSymbol = $interpolate.endSymbol(); + + forEach(whens, function(expression, key) { + whensExpFns[key] = + $interpolate(expression.replace(BRACE, startSymbol + numberExp + '-' + + offset + endSymbol)); + }); + + scope.$watch(function() { + var value = parseFloat(scope.$eval(numberExp)); + + if (!isNaN(value)) { + //if explicit number rule such as 1, 2, 3... is defined, just use it.
