Esprima is created and maintained by [Ariya Hidayat](http://twitter.com/ariyahidayat), with the help of [many contributors](https://github.com/ariya/esprima/contributors). **Esprima-FB** is a fork of the [Harmony branch](https://github.com/ariya/esprima/tree/harmony) of Esprima that implements [JSX specification](https://github.com/facebook/jsx) on top of ECMAScript syntax. ### Features - Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm)) - Experimental support for ES6/Harmony (module, class, destructuring, ...) - Full support for [JSX syntax extensions](https://github.com/facebook/jsx). - Sensible [syntax tree format](https://github.com/facebook/jsx/blob/master/AST.md) compatible with Mozilla [Parser AST](https://developer.mozilla.org/en/SpiderMonkey/Parser_API) - Optional tracking of syntax node location (index-based and line-column) - Heavily tested (> 650 [unit tests](http://esprima.org/test/) with [full code coverage](http://esprima.org/test/coverage.html)) - Ongoing support for ES6/Harmony (module, class, destructuring, ...) ### Versioning rules In order to follow semver rules and keep reference to original Esprima versions at the same time, we left 3 digits of each version part to refer to upstream harmony branch. We then take the most significant digit. **Example:** 4001.3001.0000-dev-harmony-fb aligns with 1.1.0-dev-harmony (aka 001.001.000-dev-harmony) in upstream, with our own changes on top. Esprima-FB serves as a **building block** for JSX language tools and transpiler implementations (such as [React](https://github.com/facebook/react) or [JSXDOM](https://github.com/vjeux/jsxdom)). Esprima-FB runs on many popular web browsers, as well as other ECMAScript platforms such as [Rhino](http://www.mozilla.org/rhino) and [Node.js](https://npmjs.org/package/esprima).

* * # The array notation * * It is often desirable to inline Injected functions and that's when setting the `$inject` property is very * inconvenient. In these situations using the array notation to specify the dependencies in a way that survives * minification is a better choice: * * 
 *   // We wish to write this (not minification / obfuscation safe)

`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.

 *
* * - 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('

* * 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](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 `$q.defer()`. * * The purpose of the deferred object is to expose the associated Promise instance as well as apis * that can be used for signaling the successful or unsuccessful completion of the task. * * **Methods** * * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection * constructed via `$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`. * * **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)` – regardless of when the promise was or will be resolved * or rejected 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. * * This method *returns a new promise* which is resolved or rejected via the return value of the * `successCallback` or `errorCallback`. * * * # Chaining promises * * Because calling `then` api 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 it's 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 promises are recognized by the templating engine in angular, which means that in templates * you can treat promises attached to a scope as if they were the resulting values. * - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains * all the important functionality needed for common async tasks. */ function $QProvider() { this.$get = ['$rootScope', '$exceptionHandler', function($rootScope, $exceptionHandler) { return qFactory(function(callback) { $rootScope.$evalAsync(callback); }, $exceptionHandler); }]; } /** * Constructs a promise manager. * * @param {function(function)} nextTick Function for executing functions in the next turn. * @param {function(...*)} exceptionHandler Function into which unexpected exceptions are passed for * debugging purposes. * @returns {object} Promise manager. */ function qFactory(nextTick, exceptionHandler) { /** * @ngdoc * @name ng.$q#defer * @methodOf ng.$q * @description * Creates a `Deferred` object which represents a task which will finish in the future. * * @returns {Deferred} Returns a new instance of deferred. */ var defer = function() { var pending = [], value, deferred; deferred = { resolve: function(val) { if (pending) { var callbacks = pending; pending = undefined; value = ref(val); if (callbacks.length) { nextTick(function() { var callback; for (var i = 0, ii = callbacks.length; i < ii; i++) { callback = callbacks[i]; value.then(callback[0], callback[1]); } }); } } }, reject: function(reason) { deferred.resolve(reject(reason)); }, promise: { then: function(callback, errback) { var result = defer(); var wrappedCallback = function(value) { try { result.resolve((callback || defaultCallback)(value)); } catch(e) { exceptionHandler(e); result.reject(e); } }; var wrappedErrback = function(reason) { try { result.resolve((errback || defaultErrback)(reason)); } catch(e) { exceptionHandler(e); result.reject(e); } }; if (pending) { pending.push([wrappedCallback, wrappedErrback]); } else { value.then(wrappedCallback, wrappedErrback); } return result.promise; } } }; return deferred; }; var ref = function(value) { if (value && value.then) return value; return { then: function(callback) { var result = defer(); nextTick(function() { result.resolve(callback(value)); }); return result.promise; } }; }; /** * @ngdoc * @name ng.$q#reject * @methodOf ng.$q * @description * Creates a promise that is resolved as rejected with the specified `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`. * * 
     *   $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
     *     });
     *
* * 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: * * 
     *   $http.get('/someUrl').success(successCallback);
     *   $http.post('/someUrl', data).success(successCallback);
     *
* * Complete list of shortcut methods: * * - {@link ng.$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. * * 
     *   // 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
     *     }
     *   });

* * * # 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 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: * 
     * ['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 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.}` – 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.}` – * 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 $cacheFactory}, this cache will be used for * caching. * - **timeout** – `{number}` – timeout in milliseconds. * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 * requests with credentials} for more information. * * @returns {HttpPromise} Returns a {@link ng.$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. This is primarily meant to be used for debugging purposes. * * * @example

/**
 * @ngdoc directive
 * @name ng.directive:ngCloak
 *
 * @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 typically a fine-grained application is
 * prefered in order to benefit from progressive rendering of the browser view.
 *
 * `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and
 *  `angular.min.js` files. Following is the css rule:
 *
 * 
 * [ng\:cloak], [ng-cloak], .ng-cloak {
 *   display: none;
 * }
 * 

 *
 * When this css rule is loaded by the browser, all html elements (including their children) that
 * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
 * during the compilation of the template it deletes the `ngCloak` element attribute, which
 * makes the compiled element visible.
 *
 * For the best result, `angular.js` script must be loaded in the head section of the html file;
 * 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 `ngCloak` directive as shown in the example below.
 *
 * @element ANY
 *
 * @example

 * The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular

 *
 * MVC components in angular:
 *
 * * Model — The Model is data in scope properties; scopes are attached to the DOM.
 * * View — The template (HTML with data bindings) is rendered into the View.
 * * Controller — The `ngController` directive specifies a Controller class; the class has
 *   methods that typically express the business logic behind the application.
 *
 * Note that an alternative way to define controllers is via the `{@link ng.$route}`
 * service.

 * 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.

/**
 * @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 and the rules 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 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:
 *
 * 
 * 
 * 
 *

 *
 * 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 correspoding strings.
 * @param {number=} offset Offset to deduct from the total number.
 *
 * @example
    
      
        
        

          Person 1:

          Person 2:

          Number of People:


          
          Without Offset:

/**
 * @ngdoc directive
 * @name ng.directive:ngRepeat
 *
 * @description
 * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
 * instance gets its own scope, where the given loop variable is set to the current collection item,
 * and `$index` is set to the item index or key.
 *
 * Special properties are exposed on the local scope of each template instance, including:
 *
 *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
 *   * `$first` – `{boolean}` – true if the repeated element is first in the iterator.
 *   * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.
 *   * `$last` – `{boolean}` – true if the repeated element is last in the iterator.
 *
 *
 * @element ANY
 * @scope
 * @priority 1000
 * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. Two
 *   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: `track in cd.tracks`.
 *
 *   * `(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}`.
 *
 * @example
 * This example initializes the scope to a list of names and
 * then uses `ngRepeat` to display every person:
