The function's name must be lowercase. +In the definition, the first argument is the less object, and subsequent arguments are from the less function call. +Values passed to the function are types defined within less, the return value may be either one of them or primitive. +See the LESS documentation for more information on the available types. + +#### report +Choices: `'min'`, `'gzip'` +Default: `'min'` + +Either report only minification result or report minification and gzip results. +This is useful to see exactly how well clean-css is performing but using `'gzip'` will make the task take 5-10x longer to complete.

Although originally designed for +use with [node.js](http://nodejs.org), it can also be used directly in the +browser. Also supports [component](https://github.com/component/component). + +Async provides around 20 functions that include the usual 'functional' +suspects (map, reduce, filter, each…) as well as some common patterns +for asynchronous control flow (parallel, series, waterfall…). All these +functions assume you follow the node.js convention of providing a single +callback as the last argument of your async function. + + +## Quick Examples + +```javascript +async.map(['file1','file2','file3'], fs.stat, function(err, results){ + // results is now an array of stats for each file +}); + +async.filter(['file1','file2','file3'], fs.exists, function(results){ + // results now equals an array of the existing files +}); + +async.parallel([ + function(){ ... }, + function(){ ... } +], callback); + +async.series([ + function(){ ... }, + function(){ ... } +]); +``` + +There are many more functions available so take a look at the docs below for a +full list. This module aims to be comprehensive, so if you feel anything is +missing please create a GitHub issue for it. + +## Common Pitfalls + +### Binding a context to an iterator + +This section is really about bind, not about async. If you are wondering how to +make async execute your iterators in a given context, or are confused as to why +a method of another library isn't working as an iterator, study this example: + +```js +// Here is a simple object with an (unnecessarily roundabout) squaring method +var AsyncSquaringLibrary = { + squareExponent: 2, + square: function(number, callback){ + var result = Math.pow(number, this.squareExponent); + setTimeout(function(){ + callback(null, result); + }, 200); + } +}; + +async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){ + // result is [NaN, NaN, NaN] + // This fails because the `this.squareExponent` expression in the square + // function is not evaluated in the context of AsyncSquaringLibrary, and is + // therefore undefined. +}); + +async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){ + // result is [1, 4, 9] + // With the help of bind we can attach a context to the iterator before + // passing it to async. Now the square function will be executed in its + // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent` + // will be as expected. +}); +``` + +## Download + +The source is available for download from +[GitHub](http://github.com/caolan/async). +Alternatively, you can install using Node Package Manager (npm): + + npm install async + +__Development:__ [async.js](https://github.com/caolan/async/raw/master/lib/async.js) - 29.6kb Uncompressed + +## In the Browser + +So far it's been tested in IE6, IE7, IE8, FF3.6 and Chrome 5.

Results will always be passed + but if an error occurred, no other tasks will be performed, and the results + object will only contain partial results. + + +__Example__ + +```js +async.auto({ + get_data: function(callback){ + // async code to get some data + }, + make_folder: function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + }, + write_file: ['get_data', 'make_folder', function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + callback(null, filename); + }], + email_link: ['write_file', function(callback, results){ + // once the file is written let's email a link to it... + // results.write_file contains the filename returned by write_file. + }] +}); +``` + +This is a fairly trivial example, but to do this using the basic parallel and +series functions would look like this: + +```js +async.parallel([ + function(callback){ + // async code to get some data + }, + function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + } +], +function(err, results){ + async.series([ + function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + }, + function(callback){ + // once the file is written let's email a link to it... + } + ]); +}); +``` + +For a complicated series of async tasks using the auto function makes adding +new tasks much easier and makes the code more readable. + + +--------------------------------------- + + +### iterator(tasks) + +Creates an iterator function which calls the next function in the array, +returning a continuation to call the next one after that. It's also possible to +'peek' the next iterator by doing iterator.next(). + +This function is used internally by the async module but can be useful when +you want to manually control the flow of functions in series. + +__Arguments__ + +* tasks - An array of functions to run. + +__Example__ + +```js +var iterator = async.iterator([ + function(){ sys.p('one'); }, + function(){ sys.p('two'); }, + function(){ sys.p('three'); } +]); + +node> var iterator2 = iterator(); +'one' +node> var iterator3 = iterator2(); +'two' +node> iterator3(); +'three' +node> var nextfn = iterator2.next(); +node> nextfn(); +'three' +``` + +--------------------------------------- + + +### apply(function, arguments..) + +Creates a continuation function with some arguments already applied, a useful +shorthand when combined with other control flow functions. Any arguments +passed to the returned function are added to the arguments originally passed +to apply. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to automatically apply when the + continuation is called. + +__Example__ + +```js +// using apply + +async.parallel([ + async.apply(fs.writeFile, 'testfile1', 'test1'), + async.apply(fs.writeFile, 'testfile2', 'test2'), +]); + + +// the same process without using apply + +async.parallel([ + function(callback){ + fs.writeFile('testfile1', 'test1', callback); + }, + function(callback){ + fs.writeFile('testfile2', 'test2', callback); + } +]); +``` + +It's possible to pass any number of additional arguments when calling the +continuation: + +```js +node> var fn = async.apply(sys.puts, 'one'); +node> fn('two', 'three'); +one +two +three +``` + +--------------------------------------- + + +### nextTick(callback) + +Calls the callback on a later loop around the event loop. In node.js this just +calls process.nextTick, in the browser it falls back to setImmediate(callback) +if available, otherwise setTimeout(callback, 0), which means other higher priority +events may precede the execution of the callback. + +This is used internally for browser-compatibility purposes. + +__Arguments__ + +* callback - The function to call on a later loop around the event loop. + +__Example__ + +```js +var call_order = []; +async.nextTick(function(){ + call_order.push('two'); + // call_order now equals ['one','two'] +}); +call_order.push('one') +``` + + +### times(n, callback) + +Calls the callback n times and accumulates results in the same manner +you would use with async.map. + +__Arguments__ + +* n - The number of times to run the function. +* callback - The function to call n times. + +__Example__ + +```js +// Pretend this is some complicated async factory +var createUser = function(id, callback) { + callback(null, { + id: 'user' + id + }) +} +// generate 5 users +async.times(5, function(n, next){ + createUser(n, function(err, user) { + next(err, user) + }) +}, function(err, users) { + // we should now have 5 users +}); +``` + + +### timesSeries(n, callback) + +The same as times only the iterator is applied to each item in the array in +series. The next iterator is only called once the current one has completed +processing. The results array will be in the same order as the original. + + +## Utils + + +### memoize(fn, [hasher]) + +Caches the results of an async function. When creating a hash to store function +results against, the callback is omitted from the hash and an optional hash +function can be used. + +The cache of results is exposed as the `memo` property of the function returned +by `memoize`. + +__Arguments__ + +* fn - the function you to proxy and cache results from. +* hasher - an optional function for generating a custom hash for storing + results, it has all the arguments applied to it apart from the callback, and + must be synchronous. + +__Example__ + +```js +var slow_fn = function (name, callback) { + // do something + callback(null, result); +}; +var fn = async.memoize(slow_fn); + +// fn can now be used as if it were slow_fn +fn('some name', function () { + // callback +}); +``` + + +### unmemoize(fn) + +Undoes a memoized function, reverting it to the original, unmemoized +form. Comes handy in tests. + +__Arguments__ + +* fn - the memoized function + + +### log(function, arguments) + +Logs the result of an async function to the console. Only works in node.js or +in browsers that support console.log and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.log is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, 'hello ' + name); + }, 1000); +}; +``` +```js +node> async.log(hello, 'world'); +'hello world' +``` + +--------------------------------------- + + +### dir(function, arguments) + +Logs the result of an async function to the console using console.dir to +display the properties of the resulting object. Only works in node.js or +in browsers that support console.dir and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.dir is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, {hello: name}); + }, 1000); +}; +``` +```js +node> async.dir(hello, 'world'); +{hello: 'world'} +``` + +--------------------------------------- + + +### noConflict() + +Changes the value of async back to its original value, returning a reference to the +async object. diff --git a/node_modules/grunt-contrib-less/node_modules/async/component.json b/node_modules/grunt-contrib-less/node_modules/async/component.json new file mode 100644 index 0000000..bbb0115 --- /dev/null +++ b/node_modules/grunt-contrib-less/node_modules/async/component.json @@ -0,0 +1,11 @@ +{ + "name": "async", + "repo": "caolan/async", + "description": "Higher-order functions and common patterns for asynchronous code", + "version": "0.1.23", + "keywords": [], + "dependencies": {}, + "development": {}, + "main": "lib/async.js", + "scripts": [ "lib/async.js" ] +} diff --git a/node_modules/grunt-contrib-less/node_modules/async/lib/async.js b/node_modules/grunt-contrib-less/node_modules/async/lib/async.js new file mode 100755 index 0000000..1eebb15 --- /dev/null +++ b/node_modules/grunt-contrib-less/node_modules/async/lib/async.js @@ -0,0 +1,958 @@ +/*global setImmediate: false, setTimeout: false, console: false */ +(function () { + + var async = {};

Each function can optionally depend on other functions being completed +first, and each function is run as soon as its requirements are satisfied. + +If any of the functions pass an error to their callback, it will not +complete (so any other functions depending on it will not run), and the main +`callback` is immediately called with the error. Functions also receive an +object containing the results of functions which have completed so far. + +Note, all functions are called with a `results` object as a second argument, +so it is unsafe to pass functions in the `tasks` object which cannot handle the +extra argument. + +For example, this snippet of code: + +```js +async.auto({ + readData: async.apply(fs.readFile, 'data.txt', 'utf-8') +}, callback); +``` + +will have the effect of calling `readFile` with the results object as the last +argument, which will fail: + +```js +fs.readFile('data.txt', 'utf-8', cb, {}); +``` + +Instead, wrap the call to `readFile` in a function which does not forward the +`results` object: + +```js +async.auto({ + readData: function(cb, results){ + fs.readFile('data.txt', 'utf-8', cb); + } +}, callback); +``` + +__Arguments__ + +* `tasks` - An object. Each of its properties is either a function or an array of + requirements, with the function itself the last item in the array. The object's key + of a property serves as the name of the task defined by that property, + i.e. can be used when specifying requirements for other tasks. + The function receives two arguments: (1) a `callback(err, result)` which must be + called when finished, passing an `error` (which can be `null`) and the result of + the function's execution, and (2) a `results` object, containing the results of + the previously executed functions. +* `callback(err, results)` - An optional callback which is called when all the + tasks have been completed. It receives the `err` argument if any `tasks` + pass an error to their callback. Results are always returned; however, if + an error occurs, no further `tasks` will be performed, and the results + object will only contain partial results. + + +__Example__ + +```js +async.auto({ + get_data: function(callback){ + console.log('in get_data'); + // async code to get some data + callback(null, 'data', 'converted to array'); + }, + make_folder: function(callback){ + console.log('in make_folder'); + // async code to create a directory to store a file in + // this is run at the same time as getting the data + callback(null, 'folder'); + }, + write_file: ['get_data', 'make_folder', function(callback, results){ + console.log('in write_file', JSON.stringify(results)); + // once there is some data and the directory exists, + // write the data to a file in the directory + callback(null, 'filename'); + }], + email_link: ['write_file', function(callback, results){ + console.log('in email_link', JSON.stringify(results)); + // once the file is written let's email a link to it... + // results.write_file contains the filename returned by write_file. + callback(null, {'file':results.write_file, 'email':'user@example.com'}); + }] +}, function(err, results) { + console.log('err = ', err); + console.log('results = ', results); +}); +``` + +This is a fairly trivial example, but to do this using the basic parallel and +series functions would look like this: + +```js +async.parallel([ + function(callback){ + console.log('in get_data'); + // async code to get some data + callback(null, 'data', 'converted to array'); + }, + function(callback){ + console.log('in make_folder'); + // async code to create a directory to store a file in + // this is run at the same time as getting the data + callback(null, 'folder'); + } +], +function(err, results){ + async.series([ + function(callback){ + console.log('in write_file', JSON.stringify(results)); + // once there is some data and the directory exists, + // write the data to a file in the directory + results.push('filename'); + callback(null); + }, + function(callback){ + console.log('in email_link', JSON.stringify(results)); + // once the file is written let's email a link to it... + callback(null, {'file':results.pop(), 'email':'user@example.com'}); + } + ]); +}); +``` + +For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding +new tasks much easier (and the code more readable). + + +--------------------------------------- + + +### retry([times = 5], task, [callback]) + +Attempts to get a successful response from `task` no more than `times` times before +returning an error. If the task is successful, the `callback` will be passed the result +of the successfull task. If all attemps fail, the callback will be passed the error and +result (if any) of the final attempt. + +__Arguments__ + +* `times` - An integer indicating how many times to attempt the `task` before giving up. Defaults to 5. +* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)` + which must be called when finished, passing `err` (which can be `null`) and the `result` of + the function's execution, and (2) a `results` object, containing the results of + the previously executed functions (if nested inside another control flow). +* `callback(err, results)` - An optional callback which is called when the + task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`. + +The [`retry`](#retry) function can be used as a stand-alone control flow by passing a +callback, as shown below: + +```js +async.retry(3, apiMethod, function(err, result) { + // do something with the result +}); +``` + +It can also be embeded within other control flow functions to retry individual methods +that are not as reliable, like this: + +```js +async.auto({ + users: api.getUsers.bind(api), + payments: async.retry(3, api.getPayments.bind(api)) +}, function(err, results) { + // do something with the results +}); +``` + + +--------------------------------------- + + +### iterator(tasks) + +Creates an iterator function which calls the next function in the `tasks` array, +returning a continuation to call the next one after that. It's also possible to +“peek” at the next iterator with `iterator.next()`. + +This function is used internally by the `async` module, but can be useful when +you want to manually control the flow of functions in series. + +__Arguments__ + +* `tasks` - An array of functions to run. + +__Example__ + +```js +var iterator = async.iterator([ + function(){ sys.p('one'); }, + function(){ sys.p('two'); }, + function(){ sys.p('three'); } +]); + +node> var iterator2 = iterator(); +'one' +node> var iterator3 = iterator2(); +'two' +node> iterator3(); +'three' +node> var nextfn = iterator2.next(); +node> nextfn(); +'three' +``` + +--------------------------------------- + + +### apply(function, arguments..) + +Creates a continuation function with some arguments already applied. + +Useful as a shorthand when combined with other control flow functions. Any arguments +passed to the returned function are added to the arguments originally passed +to apply. + +__Arguments__ + +* `function` - The function you want to eventually apply all arguments to. +* `arguments...` - Any number of arguments to automatically apply when the + continuation is called. + +__Example__ + +```js +// using apply + +async.parallel([ + async.apply(fs.writeFile, 'testfile1', 'test1'), + async.apply(fs.writeFile, 'testfile2', 'test2'), +]); + + +// the same process without using apply + +async.parallel([ + function(callback){ + fs.writeFile('testfile1', 'test1', callback); + }, + function(callback){ + fs.writeFile('testfile2', 'test2', callback); + } +]); +``` + +It's possible to pass any number of additional arguments when calling the +continuation: + +```js +node> var fn = async.apply(sys.puts, 'one'); +node> fn('two', 'three'); +one +two +three +``` + +--------------------------------------- + + +### nextTick(callback) + +Calls `callback` on a later loop around the event loop. In Node.js this just +calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)` +if available, otherwise `setTimeout(callback, 0)`, which means other higher priority +events may precede the execution of `callback`. + +This is used internally for browser-compatibility purposes. + +__Arguments__ + +* `callback` - The function to call on a later loop around the event loop. + +__Example__ + +```js +var call_order = []; +async.nextTick(function(){ + call_order.push('two'); + // call_order now equals ['one','two'] +}); +call_order.push('one') +``` + + +### times(n, callback) + +Calls the `callback` function `n` times, and accumulates results in the same manner +you would use with [`map`](#map). + +__Arguments__ + +* `n` - The number of times to run the function. +* `callback` - The function to call `n` times. + +__Example__ + +```js +// Pretend this is some complicated async factory +var createUser = function(id, callback) { + callback(null, { + id: 'user' + id + }) +} +// generate 5 users +async.times(5, function(n, next){ + createUser(n, function(err, user) { + next(err, user) + }) +}, function(err, users) { + // we should now have 5 users +}); +``` + + +### timesSeries(n, callback) + +The same as [`times`](#times), only the iterator is applied to each item in `arr` in +series. The next `iterator` is only called once the current one has completed. +The results array will be in the same order as the original. + + +## Utils + + +### memoize(fn, [hasher]) + +Caches the results of an `async` function. When creating a hash to store function +results against, the callback is omitted from the hash and an optional hash +function can be used. + +The cache of results is exposed as the `memo` property of the function returned +by `memoize`. + +__Arguments__ + +* `fn` - The function to proxy and cache results from. +* `hasher` - Tn optional function for generating a custom hash for storing + results. It has all the arguments applied to it apart from the callback, and + must be synchronous. + +__Example__ + +```js +var slow_fn = function (name, callback) { + // do something + callback(null, result); +}; +var fn = async.memoize(slow_fn); + +// fn can now be used as if it were slow_fn +fn('some name', function () { + // callback +}); +``` + + +### unmemoize(fn) + +Undoes a [`memoize`](#memoize)d function, reverting it to the original, unmemoized +form. Handy for testing. + +__Arguments__ + +* `fn` - the memoized function + + +### log(function, arguments) + +Logs the result of an `async` function to the `console`. Only works in Node.js or +in browsers that support `console.log` and `console.error` (such as FF and Chrome). +If multiple arguments are returned from the async function, `console.log` is +called on each argument in order. + +__Arguments__ + +* `function` - The function you want to eventually apply all arguments to. +* `arguments...` - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, 'hello ' + name); + }, 1000); +}; +``` +```js +node> async.log(hello, 'world'); +'hello world' +``` + +--------------------------------------- + + +### dir(function, arguments) + +Logs the result of an `async` function to the `console` using `console.dir` to +display the properties of the resulting object. Only works in Node.js or +in browsers that support `console.dir` and `console.error` (such as FF and Chrome). +If multiple arguments are returned from the async function, `console.dir` is +called on each argument in order. + +__Arguments__ + +* `function` - The function you want to eventually apply all arguments to. +* `arguments...` - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, {hello: name});

This means if you attempt to parse a string like +`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be: + +```javascript +{ + a: { + b: { + c: { + d: { + e: { + f: { + '[g][h][i]': 'j' + } + } + } + } + } + } +} +``` + +This depth can be overridden by passing a `depth` option to `Qs.parse(string, depth)`: + +```javascript +Qs.parse('a[b][c][d][e][f][g][h][i]=j', 1); +// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } } +``` + +The depth limit mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. + +### Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +Qs.parse('a[]=b&a[]=c'); +// { a: ['b', 'c'] } +``` + +You may specify an index as well: + +```javascript +Qs.parse('a[1]=c&a[0]=b'); +// { a: ['b', 'c'] } +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number +to create an array.

All can be used as pure functions and don't need to be "bound". + +parseDate(string[,strict]) +----------------- + +Parse a cookie date string into a `Date`. Parses according to RFC6265 Section 5.1.1, not `Date.parse()`. If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. "Thu, 01 Jan 1970 00:00:010 GMT" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid). + +formatDate(date) +---------------- + +Format a Date into a RFC1123 string (the RFC6265-recommended format). + +canonicalDomain(str) +-------------------- + +Transforms a domain-name into a canonical domain-name. The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265). For the most part, this function is idempotent (can be run again on its output without ill effects). + +domainMatch(str,domStr[,canonicalize=true]) +------------------------------------------- + +Answers "does this real domain match the domain in a cookie?". The `str` is the "current" domain-name and the `domStr` is the "cookie" domain-name. Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a "suffix match". + +The `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not. + +defaultPath(path) +----------------- + +Given a current request/response path, gives the Path apropriate for storing in a cookie. This is basically the "directory" of a "file" in the path, but is specified by Section 5.1.4 of the RFC. + +The `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.). This is the `.pathname` property of node's `uri.parse()` output. + +pathMatch(reqPath,cookiePath) +----------------------------- + +Answers "does the request-path path-match a given cookie-path?" as per RFC6265 Section 5.1.4. Returns a boolean. + +This is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`. + +parse(header[,strict=false]) +---------------------------- + +alias for `Cookie.parse(header[,strict])` + +fromJSON(string) +---------------- + +alias for `Cookie.fromJSON(string)` + +getPublicSuffix(hostname) +------------------------- + +Returns the public suffix of this hostname. The public suffix is the shortest domain-name upon which a cookie can be set. Returns `null` if the hostname cannot have cookies set for it. + +For example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`. + +For further information, see http://publicsuffix.org/. This module derives its list from that site. + +cookieCompare(a,b) +------------------ + +For use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). Longest `.path`s go first, then sorted oldest to youngest. + +``` javascript +var cookies = [ /* unsorted array of Cookie objects */ ]; +cookies = cookies.sort(cookieCompare); +``` + +permuteDomain(domain) +--------------------- + +Generates a list of all possible domains that `domainMatch()` the parameter. May be handy for implementing cookie stores. + + +permutePath(path) +----------------- + +Generates a list of all possible paths that `pathMatch()` the parameter. May be handy for implementing cookie stores. + +Cookie +====== + +Cookie.parse(header[,strict=false]) +----------------------------------- + +Parses a single Cookie or Set-Cookie HTTP header into a `Cookie` object. Returns `undefined` if the string can't be parsed. If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265. Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off. + +Here's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response: + +``` javascript +if (res.headers['set-cookie'] instanceof Array) + cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); }); +else + cookies = [Cookie.parse(res.headers['set-cookie'])]; +``` + +Cookie.fromJSON(string) +----------------------- + +Convert a JSON string to a `Cookie` object. Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects. + +Properties +========== + + * _key_ - string - the name or key of the cookie (default "") + * _value_ - string - the value of the cookie (default "") + * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `"Infinity"`). See `setExpires()` + * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie. May also be set to strings `"Infinity"` and `"-Infinity"` for non-expiry and immediate-expiry, respectively. See `setMaxAge()` + * _domain_ - string - the `Domain=` attribute of the cookie + * _path_ - string - the `Path=` of the cookie + * _secure_ - boolean - the `Secure` cookie flag + * _httpOnly_ - boolean - the `HttpOnly` cookie flag + * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside) + +After a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes: + + * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied) + * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one. + * _created_ - `Date` - when this cookie was added to the jar + * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented. Using `cookiejar.getCookies(...)` will update this attribute. + +Construction([{options}]) +------------ + +Receives an options object that can contain any Cookie properties, uses the default for unspecified properties. + +.toString() +----------- + +encode to a Set-Cookie header value. The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`. + +.cookieString() +--------------- + +encode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '='). + +.setExpires(String) +------------------- + +sets the expiry based on a date-string passed through `parseDate()`. If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `"Infinity"` (a string) is set. + +.setMaxAge(number) +------------------- + +sets the maxAge in seconds. Coerces `-Infinity` to `"-Infinity"` and `Infinity` to `"Infinity"` so it JSON serializes correctly. + +.expiryTime([now=Date.now()]) +----------------------------- + +.expiryDate([now=Date.now()]) +----------------------------- + +expiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object. Note that in both cases the `now` parameter should be milliseconds. + +Max-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute. + +If Expires (`.expires`) is set, that's returned. + +Otherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for "Tue, 19 Jan 2038 03:14:07 GMT" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents). + +.TTL([now=Date.now()]) +--------- + +compute the TTL relative to `now` (milliseconds). The same precedence rules as for `expiryTime`/`expiryDate` apply. + +The "number" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired. Otherwise a time-to-live in milliseconds is returned. + +.canonicalizedDoman() +--------------------- + +.cdomain() +---------- + +return the canonicalized `.domain` field. This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters. + +.validate() +----------- + +Status: *IN PROGRESS*. Works for a few things, but is by no means comprehensive. + +validates cookie attributes for semantic correctness. Useful for "lint" checking any Set-Cookie headers you generate. For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct: + +``` javascript +if (cookie.validate() === true) { + // it's tasty +} else { + // yuck! +} +``` + +CookieJar +========= + +Construction([store = new MemoryCookieStore()][, rejectPublicSuffixes]) +------------ + +Simply use `new CookieJar()`. If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used. + + +Attributes +---------- + + * _rejectPublicSuffixes_ - boolean - reject cookies with domains like "com" and "co.uk" (default: `true`) + +Since eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods. + +.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie)) +------------------------------------------------------------------- + +Attempt to set the cookie in the cookie jar. If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through. The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties. + +The `options` object can be omitted and can have the following properties: + + * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies. + * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`. + * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies + * _strict_ - boolean - default `false` - perform extra checks + * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains. CookieStore errors aren't ignored by this option. + +As per the RFC, the `.hostOnly` property is set if there was no "Domain=" parameter in the cookie string (or `.domain` was null on the Cookie object). The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case. Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual). + +.setCookieSync(cookieOrString, currentUrl, [{options}]) +------------------------------------------------------- + +Synchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.storeCookie(cookie, [{options},] cb(err,cookie)) +------------------------------------------------- + +__REMOVED__ removed in lieu of the CookieStore API below + +.getCookies(currentUrl, [{options},] cb(err,cookies)) +----------------------------------------------------- + +Retrieve the list of cookies that can be sent in a Cookie header for the current url. + +If an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed. The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given. + +The `options` object can be omitted and can have the following properties: + + * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies. + * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`. + * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies + * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store. Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially). + * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it). + +The `.lastAccessed` property of the returned cookies will have been updated. + +.getCookiesSync(currentUrl, [{options}]) +---------------------------------------- + +Synchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.getCookieString(...) +--------------------- + +Accepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback. Simply maps the `Cookie` array via `.cookieString()`. + +.getCookieStringSync(...) +------------------------- + +Synchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.getSetCookieStrings(...) +------------------------- + +Returns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`. Simply maps the cookie array via `.toString()`. + +.getSetCookieStringsSync(...) +----------------------------- + +Synchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +Store +===== + +Base class for CookieJar stores. + +# CookieStore API + +The storage model for each `CookieJar` instance can be replaced with a custom implementation. The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file. The API uses continuation-passing-style to allow for asynchronous stores. + +Stores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`. Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used. + +All `domain` parameters will have been normalized before calling. + +The Cookie store must have all of the following methods. + +store.findCookie(domain, path, key, cb(err,cookie)) +--------------------------------------------------- + +Retrieve a cookie with the given domain, path and key (a.k.a. name). The RFC maintains that exactly one of these cookies should exist in a store. If the store is using versioning, this means that the latest/newest such cookie should be returned. + +Callback takes an error and the resulting `Cookie` object. If no cookie is found then `null` MUST be passed instead (i.e. not an error). + +store.findCookies(domain, path, cb(err,cookies)) +------------------------------------------------ + +Locates cookies matching the given domain and path. This is most often called in the context of `cookiejar.getCookies()` above. + +If no cookies are found, the callback MUST be passed an empty array. + +The resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method. However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done. + +As of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`. If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only). + +store.putCookie(cookie, cb(err)) +-------------------------------- + +Adds a new cookie to the store. The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur. + +The `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties. + +Pass an error if the cookie cannot be stored. + +store.updateCookie(oldCookie, newCookie, cb(err)) +------------------------------------------------- + +Update an existing cookie. The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`. The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store. + +The `.lastAccessed` property will always be different between the two objects and `.created` will always be the same. Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion). + +Stores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie. If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object. + +The `newCookie` and `oldCookie` objects MUST NOT be modified. + +Pass an error if the newCookie cannot be stored. + +store.removeCookie(domain, path, key, cb(err)) +---------------------------------------------- + +Remove a cookie from the store (see notes on `findCookie` about the uniqueness constraint). + +The implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie. + +store.removeCookies(domain, path, cb(err)) +------------------------------------------ + +Removes matching cookies from the store. The `path` paramter is optional, and if missing means all paths in a domain should be removed. + +Pass an error ONLY if removing any existing cookies failed. + +# TODO + + * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()` + * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891 + * better tests for `validate()`? + +# Copyright and License + +(tl;dr: MIT with some MPL/1.1) + +Copyright 2012- GoInstant, Inc. and other contributors.

Note that node.js v0.6.2+ bundles punycode by default.\n\nWhy the name? NPM modules `cookie`, `cookies` and `cookiejar` were already taken.\n\n# API\n\ntough\n=====\n\nFunctions on the module you get from `require('tough-cookie')`. All can be used as pure functions and don't need to be \"bound\".\n\nparseDate(string[,strict])\n-----------------\n\nParse a cookie date string into a `Date`. Parses according to RFC6265 Section 5.1.1, not `Date.parse()`. If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. \"Thu, 01 Jan 1970 00:00:010 GMT\" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid).\n\nformatDate(date)\n----------------\n\nFormat a Date into a RFC1123 string (the RFC6265-recommended format).\n\ncanonicalDomain(str)\n--------------------\n\nTransforms a domain-name into a canonical domain-name. The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265). For the most part, this function is idempotent (can be run again on its output without ill effects).\n\ndomainMatch(str,domStr[,canonicalize=true])\n-------------------------------------------\n\nAnswers \"does this real domain match the domain in a cookie?\". The `str` is the \"current\" domain-name and the `domStr` is the \"cookie\" domain-name. Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a \"suffix match\".\n\nThe `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not.\n\ndefaultPath(path)\n-----------------\n\nGiven a current request/response path, gives the Path apropriate for storing in a cookie. This is basically the \"directory\" of a \"file\" in the path, but is specified by Section 5.1.4 of the RFC.\n\nThe `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.). This is the `.pathname` property of node's `uri.parse()` output.\n\npathMatch(reqPath,cookiePath)\n-----------------------------\n\nAnswers \"does the request-path path-match a given cookie-path?\" as per RFC6265 Section 5.1.4. Returns a boolean.\n\nThis is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.\n\nparse(header[,strict=false])\n----------------------------\n\nalias for `Cookie.parse(header[,strict])`\n\nfromJSON(string)\n----------------\n\nalias for `Cookie.fromJSON(string)`\n\ngetPublicSuffix(hostname)\n-------------------------\n\nReturns the public suffix of this hostname. The public suffix is the shortest domain-name upon which a cookie can be set. Returns `null` if the hostname cannot have cookies set for it.\n\nFor example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.\n\nFor further information, see http://publicsuffix.org/. This module derives its list from that site.\n\ncookieCompare(a,b)\n------------------\n\nFor use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). Longest `.path`s go first, then sorted oldest to youngest.\n\n``` javascript\nvar cookies = [ /* unsorted array of Cookie objects */ ];\ncookies = cookies.sort(cookieCompare);\n```\n\npermuteDomain(domain)\n---------------------\n\nGenerates a list of all possible domains that `domainMatch()` the parameter. May be handy for implementing cookie stores.\n\n\npermutePath(path)\n-----------------\n\nGenerates a list of all possible paths that `pathMatch()` the parameter. May be handy for implementing cookie stores.\n\nCookie\n======\n\nCookie.parse(header[,strict=false])\n-----------------------------------\n\nParses a single Cookie or Set-Cookie HTTP header into a `Cookie` object. Returns `undefined` if the string can't be parsed. If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265. Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off.\n\nHere's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:\n\n``` javascript\nif (res.headers['set-cookie'] instanceof Array)\n cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); });\nelse\n cookies = [Cookie.parse(res.headers['set-cookie'])];\n```\n\nCookie.fromJSON(string)\n-----------------------\n\nConvert a JSON string to a `Cookie` object. Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects.\n\nProperties\n==========\n\n * _key_ - string - the name or key of the cookie (default \"\")\n * _value_ - string - the value of the cookie (default \"\")\n * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `\"Infinity\"`). See `setExpires()`\n * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie. May also be set to strings `\"Infinity\"` and `\"-Infinity\"` for non-expiry and immediate-expiry, respectively. See `setMaxAge()`\n * _domain_ - string - the `Domain=` attribute of the cookie\n * _path_ - string - the `Path=` of the cookie\n * _secure_ - boolean - the `Secure` cookie flag\n * _httpOnly_ - boolean - the `HttpOnly` cookie flag\n * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)\n\nAfter a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:\n\n * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)\n * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.\n * _created_ - `Date` - when this cookie was added to the jar\n * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented. Using `cookiejar.getCookies(...)` will update this attribute.\n\nConstruction([{options}])\n------------\n\nReceives an options object that can contain any Cookie properties, uses the default for unspecified properties.\n\n.toString()\n-----------\n\nencode to a Set-Cookie header value. The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.\n\n.cookieString()\n---------------\n\nencode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').\n\n.setExpires(String)\n-------------------\n\nsets the expiry based on a date-string passed through `parseDate()`. If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `\"Infinity\"` (a string) is set.\n\n.setMaxAge(number)\n-------------------\n\nsets the maxAge in seconds. Coerces `-Infinity` to `\"-Infinity\"` and `Infinity` to `\"Infinity\"` so it JSON serializes correctly.\n\n.expiryTime([now=Date.now()])\n-----------------------------\n\n.expiryDate([now=Date.now()])\n-----------------------------\n\nexpiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object. Note that in both cases the `now` parameter should be milliseconds.\n\nMax-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute.\n\nIf Expires (`.expires`) is set, that's returned.\n\nOtherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for \"Tue, 19 Jan 2038 03:14:07 GMT\" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).\n\n.TTL([now=Date.now()])\n---------\n\ncompute the TTL relative to `now` (milliseconds). The same precedence rules as for `expiryTime`/`expiryDate` apply.\n\nThe \"number\" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired. Otherwise a time-to-live in milliseconds is returned.\n\n.canonicalizedDoman()\n---------------------\n\n.cdomain()\n----------\n\nreturn the canonicalized `.domain` field. This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.\n\n.validate()\n-----------\n\nStatus: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.\n\nvalidates cookie attributes for semantic correctness. Useful for \"lint\" checking any Set-Cookie headers you generate. For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:\n\n``` javascript\nif (cookie.validate() === true) {\n // it's tasty\n} else {\n // yuck!\n}\n```\n\nCookieJar\n=========\n\nConstruction([store = new MemoryCookieStore()][, rejectPublicSuffixes])\n------------\n\nSimply use `new CookieJar()`. If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.\n\n\nAttributes\n----------\n\n * _rejectPublicSuffixes_ - boolean - reject cookies with domains like \"com\" and \"co.uk\" (default: `true`)\n\nSince eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.\n\n.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))\n-------------------------------------------------------------------\n\nAttempt to set the cookie in the cookie jar. If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through. The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties.\n\nThe `options` object can be omitted and can have the following properties:\n\n * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.\n * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n * _strict_ - boolean - default `false` - perform extra checks\n * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains. CookieStore errors aren't ignored by this option.\n\nAs per the RFC, the `.hostOnly` property is set if there was no \"Domain=\" parameter in the cookie string (or `.domain` was null on the Cookie object). The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case. Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).\n\n.setCookieSync(cookieOrString, currentUrl, [{options}])\n-------------------------------------------------------\n\nSynchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.storeCookie(cookie, [{options},] cb(err,cookie))\n-------------------------------------------------\n\n__REMOVED__ removed in lieu of the CookieStore API below\n\n.getCookies(currentUrl, [{options},] cb(err,cookies))\n-----------------------------------------------------\n\nRetrieve the list of cookies that can be sent in a Cookie header for the current url.\n\nIf an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed. The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.\n\nThe `options` object can be omitted and can have the following properties:\n\n * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.\n * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store. Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).\n * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it).\n\nThe `.lastAccessed` property of the returned cookies will have been updated.\n\n.getCookiesSync(currentUrl, [{options}])\n----------------------------------------\n\nSynchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getCookieString(...)\n---------------------\n\nAccepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback. Simply maps the `Cookie` array via `.cookieString()`.\n\n.getCookieStringSync(...)\n-------------------------\n\nSynchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getSetCookieStrings(...)\n-------------------------\n\nReturns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`. Simply maps the cookie array via `.toString()`.\n\n.getSetCookieStringsSync(...)\n-----------------------------\n\nSynchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\nStore\n=====\n\nBase class for CookieJar stores.\n\n# CookieStore API\n\nThe storage model for each `CookieJar` instance can be replaced with a custom implementation. The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file. The API uses continuation-passing-style to allow for asynchronous stores.\n\nStores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`. Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used.\n\nAll `domain` parameters will have been normalized before calling.\n\nThe Cookie store must have all of the following methods.\n\nstore.findCookie(domain, path, key, cb(err,cookie))\n---------------------------------------------------\n\nRetrieve a cookie with the given domain, path and key (a.k.a. name). The RFC maintains that exactly one of these cookies should exist in a store. If the store is using versioning, this means that the latest/newest such cookie should be returned.\n\nCallback takes an error and the resulting `Cookie` object. If no cookie is found then `null` MUST be passed instead (i.e. not an error).\n\nstore.findCookies(domain, path, cb(err,cookies))\n------------------------------------------------\n\nLocates cookies matching the given domain and path. This is most often called in the context of `cookiejar.getCookies()` above.\n\nIf no cookies are found, the callback MUST be passed an empty array.\n\nThe resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method. However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.\n\nAs of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`. If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).\n\nstore.putCookie(cookie, cb(err))\n--------------------------------\n\nAdds a new cookie to the store. The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.\n\nThe `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.\n\nPass an error if the cookie cannot be stored.\n\nstore.updateCookie(oldCookie, newCookie, cb(err))\n-------------------------------------------------\n\nUpdate an existing cookie. The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`. The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.\n\nThe `.lastAccessed` property will always be different between the two objects and `.created` will always be the same. Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion).\n\nStores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie. If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.\n\nThe `newCookie` and `oldCookie` objects MUST NOT be modified.\n\nPass an error if the newCookie cannot be stored.\n\nstore.removeCookie(domain, path, key, cb(err))\n----------------------------------------------\n\nRemove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).\n\nThe implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.\n\nstore.removeCookies(domain, path, cb(err))\n------------------------------------------\n\nRemoves matching cookies from the store. The `path` paramter is optional, and if missing means all paths in a domain should be removed.\n\nPass an error ONLY if removing any existing cookies failed.\n\n# TODO\n\n * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()`\n * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891\n * better tests for `validate()`?\n\n# Copyright and License\n\n(tl;dr: MIT with some MPL/1.1)\n\nCopyright 2012- GoInstant, Inc. and other contributors.

If that is you, but still want to author +in AMD style modules to get dynamic require([]), better direct source usage and +powerful loader plugin support in the browser, then this tool can help. + +#### amdefine/intercept usage + +Just require it in your top level app module (for example index.js, server.js): + +```javascript +require('amdefine/intercept'); +``` + +The module does not return a value, so no need to assign the result to a local +variable. + +Then just require() code as you normally would with Node's require(). Any .js +loaded after the intercept require will have the amdefine check injected in +the .js source as it is loaded. It does not modify the source on disk, just +prepends some content to the text of the module as it is loaded by Node. + +#### How amdefine/intercept works + +It overrides the `Module._extensions['.js']` in Node to automatically prepend +the amdefine snippet above. So, it will affect any .js file loaded by your +app. + +## define() usage + +It is best if you use the anonymous forms of define() in your module: + +```javascript +define(function (require) { + var dependency = require('dependency'); +}); +``` + +or + +```javascript +define(['dependency'], function (dependency) { + +}); +``` + +## RequireJS optimizer integration. + +Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html) +will have support for stripping the `if (typeof define !== 'function')` check +mentioned above, so you can include this snippet for code that runs in the +browser, but avoid taking the cost of the if() statement once the code is +optimized for deployment. + +## Node 0.4 Support + +If you want to support Node 0.4, then add `require` as the second parameter to amdefine: + +```javascript +//Only if you want Node 0.4. If using 0.5 or later, use the above snippet. +if (typeof define !== 'function') { var define = require('amdefine')(module, require) } +``` + +## Limitations + +### Synchronous vs Asynchronous + +amdefine creates a define() function that is callable by your code. It will +execute and trace dependencies and call the factory function *synchronously*, +to keep the behavior in line with Node's synchronous dependency tracing. + +The exception: calling AMD's callback-style require() from inside a factory +function. The require callback is called on process.nextTick(): + +```javascript +define(function (require) { + require(['a'], function(a) { + //'a' is loaded synchronously, but + //this callback is called on process.nextTick(). + }); +}); +``` + +### Loader Plugins + +Loader plugins are supported as long as they call their load() callbacks +synchronously. So ones that do network requests will not work. However plugins +like [text](http://requirejs.org/docs/api.html#text) can load text files locally. + +The plugin API's `load.fromText()` is **not supported** in amdefine, so this means +transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs) +will not work. This may be fixable, but it is a bit complex, and I do not have +enough node-fu to figure it out yet. See the source for amdefine.js if you want +to get an idea of the issues involved. + +## Tests + +To run the tests, cd to **tests** and run: + +``` +node all.js +node all-intercept.js +``` + +## License + +New BSD and MIT.

It does not modify the source on disk, just\nprepends some content to the text of the module as it is loaded by Node.\n\n#### How amdefine/intercept works\n\nIt overrides the `Module._extensions['.js']` in Node to automatically prepend\nthe amdefine snippet above. So, it will affect any .js file loaded by your\napp.\n\n## define() usage\n\nIt is best if you use the anonymous forms of define() in your module:\n\n```javascript\ndefine(function (require) {\n var dependency = require('dependency');\n});\n```\n\nor\n\n```javascript\ndefine(['dependency'], function (dependency) {\n\n});\n```\n\n## RequireJS optimizer integration. \n\nVersion 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html)\nwill have support for stripping the `if (typeof define !== 'function')` check\nmentioned above, so you can include this snippet for code that runs in the\nbrowser, but avoid taking the cost of the if() statement once the code is\noptimized for deployment.\n\n## Node 0.4 Support\n\nIf you want to support Node 0.4, then add `require` as the second parameter to amdefine:\n\n```javascript\n//Only if you want Node 0.4. If using 0.5 or later, use the above snippet.\nif (typeof define !== 'function') { var define = require('amdefine')(module, require) }\n```\n\n## Limitations\n\n### Synchronous vs Asynchronous\n\namdefine creates a define() function that is callable by your code. It will\nexecute and trace dependencies and call the factory function *synchronously*,\nto keep the behavior in line with Node's synchronous dependency tracing.\n\nThe exception: calling AMD's callback-style require() from inside a factory\nfunction. The require callback is called on process.nextTick():\n\n```javascript\ndefine(function (require) {\n require(['a'], function(a) {\n //'a' is loaded synchronously, but\n //this callback is called on process.nextTick().\n });\n});\n```\n\n### Loader Plugins\n\nLoader plugins are supported as long as they call their load() callbacks\nsynchronously. So ones that do network requests will not work. However plugins\nlike [text](http://requirejs.org/docs/api.html#text) can load text files locally.\n\nThe plugin API's `load.fromText()` is **not supported** in amdefine, so this means\ntranspiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs)\nwill not work. This may be fixable, but it is a bit complex, and I do not have\nenough node-fu to figure it out yet. See the source for amdefine.js if you want\nto get an idea of the issues involved.\n\n## Tests\n\nTo run the tests, cd to **tests** and run:\n\n```\nnode all.js\nnode all-intercept.js\n```\n\n## License\n\nNew BSD and MIT.

Setting this option to `false` speeds up the reaction time of the watch (usually 500ms faster for most) and allows subsequent task runs to share the same context. Not spawning task runs can make the watch more prone to failing so please use as needed. + +Example: +```js +watch: { + scripts: { + files: ['**/*.js'], + tasks: ['jshint'], + options: { + spawn: false, + }, + }, +}, +``` + +*For backwards compatibility the option `nospawn` is still available and will do the opposite of `spawn`.* + +#### options.interrupt +Type: `Boolean` +Default: false + +As files are modified this watch task will spawn tasks in child processes.

You can override this message by supplying your own function: + +```js +watch: { + options: { + dateFormat: function(time) { + grunt.log.writeln('The watch finished in ' + time + 'ms at' + (new Date()).toString()); + grunt.log.writeln('Waiting for more changes...'); + }, + }, + scripts: { + files: '**/*.js', + tasks: 'jshint', + }, +}, +``` + +#### options.atBegin +Type: `Boolean` +Default: false + +This option will trigger the run of each specified task at startup of the watcher. + +#### options.livereload +Type: `Boolean|Number|Object` +Default: false + +Set to `true` or set `livereload: 1337` to a port number to enable live reloading. Default and recommended port is `35729`. + +If enabled a live reload server will be started with the watch task per target. Then after the indicated tasks have ran, the live reload server will be triggered with the modified files. + +Example: +```js +watch: { + css: { + files: '**/*.sass', + tasks: ['sass'], + options: { + livereload: true, + }, + }, +}, +``` + +It's possible to get livereload working over https connections. To do this, pass an object to `livereload` with a `key` and `cert` paths specified. + +Example: +```js +watch: { + css: { + files: '**/*.sass', + tasks: ['sass'], + options: { + livereload: { + port: 9000, + key: grunt.file.read('path/to/ssl.key'), + cert: grunt.file.read('path/to/ssl.crt') + // you can pass in any other options you'd like to the https server, as listed here: http://nodejs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener + } + }, + }, +}, +``` + + +#### options.cwd +Type: `String|Object` +Default: `process.cwd()` + +Ability to set the current working directory. Defaults to `process.cwd()`. Can either be a string to set the cwd to match files and spawn tasks. Or an object to set each independently. Such as `options: { cwd: { files: 'match/files/from/here', spawn: 'but/spawn/files/from/here' } }`. + +#### options.livereloadOnError +Type: `Boolean` +Default: `true` + +Option to prevent the livereload if the executed tasks encountered an error. If set to `false`, the livereload will only be triggered if all tasks completed successfully. + +### Examples + +```js +// Simple config to run jshint any time a file is added, changed or deleted +grunt.initConfig({ + watch: { + files: ['**/*'], + tasks: ['jshint'], + }, +}); +``` + +```js +// Advanced config. Run specific tasks when specific files are added, changed or deleted. +grunt.initConfig({ + watch: { + gruntfile: { + files: 'Gruntfile.js', + tasks: ['jshint:gruntfile'], + }, + src: { + files: ['lib/*.js', 'css/**/*.scss', '!lib/dontwatch.js'], + tasks: ['default'], + }, + test: { + files: '<%= jshint.test.src %>', + tasks: ['jshint:test', 'qunit'], + }, + }, +}); +``` + +#### Using the `watch` event +This task will emit a `watch` event when watched files are modified. This is useful if you would like a simple notification when files are edited or if you're using this task in tandem with another task. Here is a simple example using the `watch` event: + +```js +grunt.initConfig({ + watch: { + scripts: { + files: ['lib/*.js'], + }, + }, +}); +grunt.event.on('watch', function(action, filepath, target) { + grunt.log.writeln(target + ': ' + filepath + ' has ' + action); +}); +``` + +**The `watch` event is not intended for replacing the standard Grunt API for configuring and running tasks. If you're trying to run tasks from within the `watch` event you're more than likely doing it wrong. Please read [configuring tasks](http://gruntjs.com/configuring-tasks).** + +##### Compiling Files As Needed +A very common request is to only compile files as needed. Here is an example that will only lint changed files with the `jshint` task: + +```js +grunt.initConfig({ + watch: { + scripts: { + files: ['lib/*.js'], + tasks: ['jshint'], + options: { + spawn: false, + }, + }, + }, + jshint: { + all: { + src: ['lib/*.js'], + }, + }, +}); + +// on watch events configure jshint:all to only run on changed file +grunt.event.on('watch', function(action, filepath) { + grunt.config('jshint.all.src', filepath); +}); +``` + +If you need to dynamically modify your config, the `spawn` option must be disabled to keep the watch running under the same context. + +If you save multiple files simultaneously you may opt for a more robust method: + +```js +var changedFiles = Object.create(null); +var onChange = grunt.util._.debounce(function() { + grunt.config('jshint.all.src', Object.keys(changedFiles)); + changedFiles = Object.create(null); +}, 200); +grunt.event.on('watch', function(action, filepath) { + changedFiles[filepath] = action; + onChange(); +}); +``` + +#### Live Reloading +Live reloading is built into the watch task. Set the option `livereload` to `true` to enable on the default port `35729` or set to a custom port: `livereload: 1337`. + +The simplest way to add live reloading to all your watch targets is by setting `livereload` to `true` at the task level. This will run a single live reload server and trigger the live reload for all your watch targets: + +```js +grunt.initConfig({ + watch: { + options: { + livereload: true, + }, + css: { + files: ['public/scss/*.scss'], + tasks: ['compass'], + }, + }, +}); +``` + +You can also configure live reload for individual watch targets or run multiple live reload servers. Just be sure if you're starting multiple servers they operate on different ports: + +```js +grunt.initConfig({ + watch: { + css: { + files: ['public/scss/*.scss'], + tasks: ['compass'], + options: { + // Start a live reload server on the default port 35729 + livereload: true, + }, + }, + another: { + files: ['lib/*.js'], + tasks: ['anothertask'], + options: { + // Start another live reload server on port 1337 + livereload: 1337, + }, + }, + dont: { + files: ['other/stuff/*'], + tasks: ['dostuff'], + }, + }, +}); +``` + +##### Enabling Live Reload in Your HTML +Once you've started a live reload server you'll be able to access the live reload script. To enable live reload on your page, add a script tag before your closing `` tag pointing to the `livereload.js` script: + +```html + +``` + +Feel free to add this script to your template situation and toggle with some sort of `dev` flag. + +##### Using Live Reload with the Browser Extension +Instead of adding a script tag to your page, you can live reload your page by installing a browser extension. Please visit [how do I install and use the browser extensions](http://feedback.livereload.com/knowledgebase/articles/86242-how-do-i-install-and-use-the-browser-extensions-) for help installing an extension for your browser. + +Once installed please use the default live reload port `35729` and the browser extension will automatically reload your page without needing the ` + +``` + +## Documentation + +### Collections + +* [each](#each) +* [eachSeries](#eachSeries) +* [eachLimit](#eachLimit) +* [map](#map) +* [mapSeries](#mapSeries) +* [mapLimit](#mapLimit) +* [filter](#filter) +* [filterSeries](#filterSeries) +* [reject](#reject) +* [rejectSeries](#rejectSeries) +* [reduce](#reduce) +* [reduceRight](#reduceRight) +* [detect](#detect) +* [detectSeries](#detectSeries) +* [sortBy](#sortBy) +* [some](#some) +* [every](#every) +* [concat](#concat) +* [concatSeries](#concatSeries) + +### Control Flow + +* [series](#series) +* [parallel](#parallel) +* [parallelLimit](#parallellimittasks-limit-callback) +* [whilst](#whilst) +* [doWhilst](#doWhilst) +* [until](#until) +* [doUntil](#doUntil) +* [forever](#forever) +* [waterfall](#waterfall) +* [compose](#compose) +* [applyEach](#applyEach) +* [applyEachSeries](#applyEachSeries) +* [queue](#queue) +* [cargo](#cargo) +* [auto](#auto) +* [iterator](#iterator) +* [apply](#apply) +* [nextTick](#nextTick) +* [times](#times) +* [timesSeries](#timesSeries) + +### Utils + +* [memoize](#memoize) +* [unmemoize](#unmemoize) +* [log](#log) +* [dir](#dir) +* [noConflict](#noConflict) + + +## Collections + + + +### each(arr, iterator, callback) + +Applies an iterator function to each item in an array, in parallel. +The iterator is called with an item from the list and a callback for when it +has finished.

If any of +the functions pass an error to their callback, that function will not complete +(so any other functions depending on it will not run) and the main callback +will be called immediately with the error. Functions also receive an object +containing the results of functions which have completed so far. + +Note, all functions are called with a results object as a second argument, +so it is unsafe to pass functions in the tasks object which cannot handle the +extra argument. For example, this snippet of code: + +```js +async.auto({ + readData: async.apply(fs.readFile, 'data.txt', 'utf-8') +}, callback); +``` + +will have the effect of calling readFile with the results object as the last +argument, which will fail: + +```js +fs.readFile('data.txt', 'utf-8', cb, {}); +``` + +Instead, wrap the call to readFile in a function which does not forward the +results object: + +```js +async.auto({ + readData: function(cb, results){ + fs.readFile('data.txt', 'utf-8', cb); + } +}, callback); +``` + +__Arguments__ + +* tasks - An object literal containing named functions or an array of + requirements, with the function itself the last item in the array. The key + used for each function or array is used when specifying requirements. The + function receives two arguments: (1) a callback(err, result) which must be + called when finished, passing an error (which can be null) and the result of + the function's execution, and (2) a results object, containing the results of + the previously executed functions. +* callback(err, results) - An optional callback which is called when all the + tasks have been completed. The callback will receive an error as an argument + if any tasks pass an error to their callback. Results will always be passed + but if an error occurred, no other tasks will be performed, and the results + object will only contain partial results. + + +__Example__ + +```js +async.auto({ + get_data: function(callback){ + // async code to get some data + }, + make_folder: function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + }, + write_file: ['get_data', 'make_folder', function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + callback(null, filename); + }], + email_link: ['write_file', function(callback, results){ + // once the file is written let's email a link to it... + // results.write_file contains the filename returned by write_file. + }] +}); +``` + +This is a fairly trivial example, but to do this using the basic parallel and +series functions would look like this: + +```js +async.parallel([ + function(callback){ + // async code to get some data + }, + function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + } +], +function(err, results){ + async.series([ + function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + }, + function(callback){ + // once the file is written let's email a link to it... + } + ]); +}); +``` + +For a complicated series of async tasks using the auto function makes adding +new tasks much easier and makes the code more readable. + + +--------------------------------------- + + +### iterator(tasks) + +Creates an iterator function which calls the next function in the array, +returning a continuation to call the next one after that. It's also possible to +'peek' the next iterator by doing iterator.next(). + +This function is used internally by the async module but can be useful when +you want to manually control the flow of functions in series. + +__Arguments__ + +* tasks - An array of functions to run. + +__Example__ + +```js +var iterator = async.iterator([ + function(){ sys.p('one'); }, + function(){ sys.p('two'); }, + function(){ sys.p('three'); } +]); + +node> var iterator2 = iterator(); +'one' +node> var iterator3 = iterator2(); +'two' +node> iterator3(); +'three' +node> var nextfn = iterator2.next(); +node> nextfn(); +'three' +``` + +--------------------------------------- + + +### apply(function, arguments..) + +Creates a continuation function with some arguments already applied, a useful +shorthand when combined with other control flow functions. Any arguments +passed to the returned function are added to the arguments originally passed +to apply. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to automatically apply when the + continuation is called. + +__Example__ + +```js +// using apply + +async.parallel([ + async.apply(fs.writeFile, 'testfile1', 'test1'), + async.apply(fs.writeFile, 'testfile2', 'test2'), +]); + + +// the same process without using apply + +async.parallel([ + function(callback){ + fs.writeFile('testfile1', 'test1', callback); + }, + function(callback){ + fs.writeFile('testfile2', 'test2', callback); + } +]); +``` + +It's possible to pass any number of additional arguments when calling the +continuation: + +```js +node> var fn = async.apply(sys.puts, 'one'); +node> fn('two', 'three'); +one +two +three +``` + +--------------------------------------- + + +### nextTick(callback) + +Calls the callback on a later loop around the event loop. In node.js this just +calls process.nextTick, in the browser it falls back to setImmediate(callback) +if available, otherwise setTimeout(callback, 0), which means other higher priority +events may precede the execution of the callback. + +This is used internally for browser-compatibility purposes. + +__Arguments__ + +* callback - The function to call on a later loop around the event loop. + +__Example__ + +```js +var call_order = []; +async.nextTick(function(){ + call_order.push('two'); + // call_order now equals ['one','two'] +}); +call_order.push('one') +``` + + +### times(n, callback) + +Calls the callback n times and accumulates results in the same manner +you would use with async.map. + +__Arguments__ + +* n - The number of times to run the function. +* callback - The function to call n times. + +__Example__ + +```js +// Pretend this is some complicated async factory +var createUser = function(id, callback) { + callback(null, { + id: 'user' + id + }) +} +// generate 5 users +async.times(5, function(n, next){ + createUser(n, function(err, user) { + next(err, user) + }) +}, function(err, users) { + // we should now have 5 users +}); +``` + + +### timesSeries(n, callback) + +The same as times only the iterator is applied to each item in the array in +series. The next iterator is only called once the current one has completed +processing. The results array will be in the same order as the original. + + +## Utils + + +### memoize(fn, [hasher]) + +Caches the results of an async function. When creating a hash to store function +results against, the callback is omitted from the hash and an optional hash +function can be used. + +The cache of results is exposed as the `memo` property of the function returned +by `memoize`. + +__Arguments__ + +* fn - the function you to proxy and cache results from. +* hasher - an optional function for generating a custom hash for storing + results, it has all the arguments applied to it apart from the callback, and + must be synchronous. + +__Example__ + +```js +var slow_fn = function (name, callback) { + // do something + callback(null, result); +}; +var fn = async.memoize(slow_fn); + +// fn can now be used as if it were slow_fn +fn('some name', function () { + // callback +}); +``` + + +### unmemoize(fn) + +Undoes a memoized function, reverting it to the original, unmemoized +form. Comes handy in tests. + +__Arguments__ + +* fn - the memoized function + + +### log(function, arguments) + +Logs the result of an async function to the console. Only works in node.js or +in browsers that support console.log and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.log is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, 'hello ' + name); + }, 1000); +}; +``` +```js +node> async.log(hello, 'world'); +'hello world' +``` + +--------------------------------------- + + +### dir(function, arguments) + +Logs the result of an async function to the console using console.dir to +display the properties of the resulting object. Only works in node.js or +in browsers that support console.dir and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.dir is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, {hello: name});

The Right Way, and the Wrong Way. + +The Wrong Way is to sit down and write an option parser. We've all done +that. + +The Right Way is to write some complex configurable program with so many +options that you go half-insane just trying to manage them all, and put +it off with duct-tape solutions until you see exactly to the core of the +problem, and finally snap and write an awesome option parser. + +If you want to write an option parser, don't write an option parser. +Write a package manager, or a source control system, or a service +restarter, or an operating system. You probably won't end up with a +good one of those, but if you don't give up, and you are relentless and +diligent enough in your procrastination, you may just end up with a very +nice option parser. + +## USAGE + + // my-program.js + var nopt = require("nopt") + , Stream = require("stream").Stream + , path = require("path") + , knownOpts = { "foo" : [String, null] + , "bar" : [Stream, Number] + , "baz" : path + , "bloo" : [ "big", "medium", "small" ] + , "flag" : Boolean + , "pick" : Boolean + , "many" : [String, Array] + } + , shortHands = { "foofoo" : ["--foo", "Mr. Foo"] + , "b7" : ["--bar", "7"] + , "m" : ["--bloo", "medium"] + , "p" : ["--pick"] + , "f" : ["--flag"] + } + // everything is optional. + // knownOpts and shorthands default to {} + // arg list defaults to process.argv + // slice defaults to 2 + , parsed = nopt(knownOpts, shortHands, process.argv, 2) + console.log(parsed) + +This would give you support for any of the following: + +```bash +$ node my-program.js --foo "blerp" --no-flag +{ "foo" : "blerp", "flag" : false } + +$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag +{ bar: 7, foo: "Mr. Hand", flag: true } + +$ node my-program.js --foo "blerp" -f -----p +{ foo: "blerp", flag: true, pick: true } + +$ node my-program.js -fp --foofoo +{ foo: "Mr. Foo", flag: true, pick: true } + +$ node my-program.js --foofoo -- -fp # -- stops the flag parsing. +{ foo: "Mr. Foo", argv: { remain: ["-fp"] } } + +$ node my-program.js --blatzk 1000 -fp # unknown opts are ok. +{ blatzk: 1000, flag: true, pick: true } + +$ node my-program.js --blatzk true -fp # but they need a value +{ blatzk: true, flag: true, pick: true } + +$ node my-program.js --no-blatzk -fp # unless they start with "no-" +{ blatzk: false, flag: true, pick: true } + +$ node my-program.js --baz b/a/z # known paths are resolved. +{ baz: "/Users/isaacs/b/a/z" } + +# if Array is one of the types, then it can take many +# values, and will always be an array.

No parsing is done. +* path: A file system path. Gets resolved against cwd if not absolute. +* url: A url. If it doesn't parse, it isn't accepted. +* Number: Must be numeric. +* Date: Must parse as a date. If it does, and `Date` is one of the options, + then it will return a Date object, not a string. +* Boolean: Must be either `true` or `false`. If an option is a boolean, + then it does not need a value, and its presence will imply `true` as + the value. To negate boolean flags, do `--no-whatever` or `--whatever + false` +* NaN: Means that the option is strictly not allowed. Any value will + fail. +* Stream: An object matching the "Stream" class in node. Valuable + for use when validating programmatically. (npm uses this to let you + supply any WriteStream on the `outfd` and `logfd` config options.) +* Array: If `Array` is specified as one of the types, then the value + will be parsed as a list of options. This means that multiple values + can be specified, and that the value will always be an array. + +If a type is an array of values not on this list, then those are +considered valid values. For instance, in the example above, the +`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`, +and any other value will be rejected. + +When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be +interpreted as their JavaScript equivalents, and numeric values will be +interpreted as a number. + +You can also mix types and values, or multiple types, in a list. For +instance `{ blah: [Number, null] }` would allow a value to be set to +either a Number or null. When types are ordered, this implies a +preference, and the first type that can be used to properly interpret +the value will be used. + +To define a new type, add it to `nopt.typeDefs`. Each item in that +hash is an object with a `type` member and a `validate` method. The +`type` member is an object that matches what goes in the type list. The +`validate` method is a function that gets called with `validate(data, +key, val)`. Validate methods should assign `data[key]` to the valid +value of `val` if it can be handled properly, or return boolean +`false` if it cannot. + +You can also call `nopt.clean(data, types, typeDefs)` to clean up a +config object and remove its invalid properties. + +## Error Handling + +By default, nopt outputs a warning to standard error when invalid +options are found. You can change this behavior by assigning a method +to `nopt.invalidHandler`. This method will be called with +the offending `nopt.invalidHandler(key, val, types)`. + +If no `nopt.invalidHandler` is assigned, then it will console.error +its whining.

When namespaces/wildcards are enabled, events can either be +strings (`foo.bar`) separated by a delimiter or arrays (`['foo', 'bar']`). The +delimiter is also configurable as a constructor option. + +An event name passed to any event emitter method can contain a wild card (the +`*` character). If the event name is a string, a wildcard may appear as `foo.*`. +If the event name is an array, the wildcard may appear as `['foo', '*']`. + +If either of the above described events were passed to the `on` method, +subsequent emits such as the following would be observed... + +```javascript + emitter.emit('foo.bazz'); + emitter.emit(['foo', 'bar']); +``` + + +### emitter.addListener(event, listener) +### emitter.on(event, listener) + +Adds a listener to the end of the listeners array for the specified event. + +```javascript + server.on('data', function(value1, value2, value3, ...) { + console.log('The event was raised!'); + }); +``` + +```javascript + server.on('data', function(value) { + console.log('The event was raised!'); + }); +``` + +### emitter.onAny(listener) + +Adds a listener that will be fired when any event is emitted. + +```javascript + server.onAny(function(value) { + console.log('All events trigger this.'); + }); +``` + +### emitter.offAny(listener) + +Removes the listener that will be fired when any event is emitted. + +```javascript + server.offAny(function(value) { + console.log('The event was raised!'); + }); +``` + +#### emitter.once(event, listener) + +Adds a **one time** listener for the event.

When an error is encountered, the + glob object is in an undefined state, and should be discarded. +* `aborted` Boolean which is set to true when calling `abort()`. There + is no way at this time to continue a glob search after aborting, but + you can re-use the statCache to avoid having to duplicate syscalls. +* `statCache` Collection of all the stat results the glob search + performed. +* `cache` Convenience object. Each field has the following possible + values: + * `false` - Path does not exist + * `true` - Path exists + * `1` - Path exists, and is not a directory + * `2` - Path exists, and is a directory + * `[file, entries, ...]` - Path exists, is a directory, and the + array value is the results of `fs.readdir` + +### Events + +* `end` When the matching is finished, this is emitted with all the + matches found. If the `nonull` option is set, and no match was found, + then the `matches` list contains the original pattern. The matches + are sorted, unless the `nosort` flag is set. +* `match` Every time a match is found, this is emitted with the matched. +* `error` Emitted when an unexpected error is encountered, or whenever + any fs error occurs if `options.strict` is set. +* `abort` When `abort()` is called, this event is raised. + +### Methods + +* `abort` Stop the search. + +### Options + +All the options that can be passed to Minimatch can also be passed to +Glob to change pattern matching behavior. Also, some have been added, +or have glob-specific ramifications. + +All options are false by default, unless otherwise noted. + +All options are added to the glob object, as well. + +* `cwd` The current working directory in which to search. Defaults + to `process.cwd()`. +* `root` The place where patterns starting with `/` will be mounted + onto. Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix + systems, and `C:\` or some such on Windows.) +* `dot` Include `.dot` files in normal matches and `globstar` matches. + Note that an explicit dot in a portion of the pattern will always + match dot files. +* `nomount` By default, a pattern starting with a forward-slash will be + "mounted" onto the root setting, so that a valid filesystem path is + returned. Set this flag to disable that behavior. +* `mark` Add a `/` character to directory matches. Note that this + requires additional stat calls. +* `nosort` Don't sort the results. +* `stat` Set to true to stat *all* results. This reduces performance + somewhat, and is completely unnecessary, unless `readdir` is presumed + to be an untrustworthy indicator of file existence. It will cause + ELOOP to be triggered one level sooner in the case of cyclical + symbolic links. +* `silent` When an unusual error is encountered + when attempting to read a directory, a warning will be printed to + stderr. Set the `silent` option to true to suppress these warnings. +* `strict` When an unusual error is encountered + when attempting to read a directory, the process will just continue on + in search of other matches. Set the `strict` option to raise an error + in these cases. +* `cache` See `cache` property above. Pass in a previously generated + cache object to save some fs calls. +* `statCache` A cache of results of filesystem information, to prevent + unnecessary stat calls. While it should not normally be necessary to + set this, you may pass the statCache from one glob() call to the + options object of another, if you know that the filesystem will not + change between calls. (See "Race Conditions" below.) +* `sync` Perform a synchronous glob search. +* `nounique` In some cases, brace-expanded patterns can result in the + same file showing up multiple times in the result set. By default, + this implementation prevents duplicates in the result set. + Set this flag to disable that behavior. +* `nonull` Set to never return an empty set, instead returning a set + containing the pattern itself. This is the default in glob(3). +* `nocase` Perform a case-insensitive match. Note that case-insensitive + filesystems will sometimes result in glob returning results that are + case-insensitively matched anyway, since readdir and stat will not + raise an error. +* `debug` Set to enable debug logging in minimatch and glob. +* `globDebug` Set to enable debug logging in glob, but not minimatch. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between node-glob and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then glob returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. + +## Windows + +**Please only use forward-slashes in glob expressions.** + +Though windows uses either `/` or `\` as its path separator, only `/` +characters are used by this glob implementation. You must use +forward-slashes **only** in glob expressions. Back-slashes will always +be interpreted as escape characters, not path separators. + +Results from absolute patterns such as `/foo/*` are mounted onto the +root setting using `path.join`. On windows, this will by default result +in `/foo/*` matching `C:\foo\bar.txt`. + +## Race Conditions + +Glob searching, by its very nature, is susceptible to race conditions, +since it relies on directory walking and such. + +As a result, it is possible that a file that exists when glob looks for +it may have been deleted or modified by the time it returns the result. + +As part of its internal implementation, this program caches all stat +and readdir calls that it makes, in order to cut down on system +overhead. However, this also makes it even more susceptible to races, +especially if the cache or statCache objects are reused between glob +calls. + +Users are thus advised not to use a glob result as a guarantee of +filesystem state in the face of rapid changes. For the vast majority +of operations, this is never a problem. diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/g.js b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/g.js new file mode 100644 index 0000000..be122df --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/g.js @@ -0,0 +1,9 @@ +var Glob = require("../").Glob + +var pattern = "test/a/**/[cg]/../[cg]" +console.log(pattern) + +var mg = new Glob(pattern, {mark: true, sync:true}, function (er, matches) { + console.log("matches", matches) +}) +console.log("after") diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/usr-local.js b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/usr-local.js new file mode 100644 index 0000000..327a425 --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/examples/usr-local.js @@ -0,0 +1,9 @@ +var Glob = require("../").Glob + +var pattern = "{./*/*,/*,/usr/local/*}" +console.log(pattern) + +var mg = new Glob(pattern, {mark: true}, function (er, matches) { + console.log("matches", matches) +}) +console.log("after") diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/glob.js b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/glob.js new file mode 100644 index 0000000..f646c44 --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/glob.js @@ -0,0 +1,728 @@ +// Approach: +// +// 1.

It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n superclass\n* new version overwrites current prototype while old one preserves any\n existing fields on it\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/isaacs/inherits/issues" + }, + "_id": "inherits@2.0.1", + "dist": { + "shasum": "b17d08d326b4423e568eff719f91b0b1cbdf69f1", + "tarball": "http://registry.npmjs.org/inherits/-/inherits-2.0.1.tgz" + }, + "_from": "inherits@2", + "_npmVersion": "1.3.8", + "_npmUser": { + "name": "isaacs", + "email": "i@izs.me" + }, + "maintainers": [ + { + "name": "isaacs", + "email": "i@izs.me" + } + ], + "directories": {}, + "_shasum": "b17d08d326b4423e568eff719f91b0b1cbdf69f1", + "_resolved": "https://registry.npmjs.org/inherits/-/inherits-2.0.1.tgz", + "homepage": "https://github.com/isaacs/inherits" +} diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/inherits/test.js b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/inherits/test.js new file mode 100644 index 0000000..fc53012 --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/inherits/test.js @@ -0,0 +1,25 @@ +var inherits = require('./inherits.js') +var assert = require('assert') + +function test(c) { + assert(c.constructor === Child) + assert(c.constructor.super_ === Parent) + assert(Object.getPrototypeOf(c) === Child.prototype) + assert(Object.getPrototypeOf(Object.getPrototypeOf(c)) === Parent.prototype) + assert(c instanceof Child) + assert(c instanceof Parent) +} + +function Child() { + Parent.call(this) + test(this) +} + +function Parent() {} + +inherits(Child, Parent) + +var c = new Child +test(c) + +console.log('ok') diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/.npmignore b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/.npmignore new file mode 100644 index 0000000..3c3629e --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/.npmignore @@ -0,0 +1 @@ +node_modules diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/LICENSE b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/LICENSE new file mode 100644 index 0000000..05a4010 --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/LICENSE @@ -0,0 +1,23 @@ +Copyright 2009, 2010, 2011 Isaac Z.

Each item in the row + corresponds to a single path-part. For example, the pattern + `{a,b/c}/d` would expand to a set of patterns like: + + [ [ a, d ] + , [ b, c, d ] ] + + If a portion of the pattern doesn't have any "magic" in it + (that is, it's something like `"foo"` rather than `fo*o?`), then it + will be left as a string rather than converted to a regular + expression. + +* `regexp` Created by the `makeRe` method. A single regular expression + expressing the entire pattern. This is useful in cases where you wish + to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. +* `negate` True if the pattern is negated. +* `comment` True if the pattern is a comment. +* `empty` True if the pattern is `""`. + +### Methods + +* `makeRe` Generate the `regexp` member if necessary, and return it. + Will return `false` if the pattern is invalid. +* `match(fname)` Return true if the filename matches the pattern, or + false otherwise. +* `matchOne(fileArray, patternArray, partial)` Take a `/`-split + filename, and match it against a single row in the `regExpSet`. This + method is mainly for internal use, but is exposed so that it can be + used by a glob-walker that needs to avoid excessive filesystem calls. + +All other methods are internal, and will be called as necessary. + +## Functions + +The top-level exported function has a `cache` property, which is an LRU +cache set to store 100 items. So, calling these methods repeatedly +with the same pattern and options will use the same Minimatch object, +saving the cost of parsing it multiple times. + +### minimatch(path, pattern, options) + +Main export. Tests a path against the pattern using the options. + +```javascript +var isJS = minimatch(file, "*.js", { matchBase: true }) +``` + +### minimatch.filter(pattern, options) + +Returns a function that tests its +supplied argument, suitable for use with `Array.filter`. Example: + +```javascript +var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) +``` + +### minimatch.match(list, pattern, options) + +Match against the list of +files, in the style of fnmatch or glob. If nothing is matched, and +options.nonull is set, then return a list containing the pattern itself. + +```javascript +var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) +``` + +### minimatch.makeRe(pattern, options) + +Make a regular expression object from the pattern. + +## Options + +All options are `false` by default. + +### debug + +Dump a ton of stuff to stderr. + +### nobrace + +Do not expand `{a,b}` and `{1..3}` brace sets. + +### noglobstar + +Disable `**` matching against multiple folder names. + +### dot + +Allow patterns to match filenames starting with a period, even if +the pattern does not explicitly have a period in that spot. + +Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` +is set. + +### noext + +Disable "extglob" style patterns like `+(a|b)`. + +### nocase + +Perform a case-insensitive match. + +### nonull + +When a match is not found by `minimatch.match`, return a list containing +the pattern itself if this option is set. When not set, an empty list +is returned if there are no matches. + +### matchBase + +If set, then patterns without slashes will be matched +against the basename of the path if it contains slashes. For example, +`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. + +### nocomment + +Suppress the behavior of treating `#` at the start of a pattern as a +comment. + +### nonegate + +Suppress the behavior of treating a leading `!` character as negation. + +### flipNegate + +Returns from negate expressions the same as if they were not negated. +(Ie, true on a hit, false on a miss.) + + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between minimatch and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then minimatch.match returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. diff --git a/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/minimatch.js b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/minimatch.js new file mode 100644 index 0000000..4539678 --- /dev/null +++ b/node_modules/grunt/node_modules/findup-sync/node_modules/glob/node_modules/minimatch/minimatch.js @@ -0,0 +1,1061 @@ +;(function (require, exports, module, platform) { + +if (module) module.exports = minimatch +else exports.minimatch = minimatch + +if (!require) { + require = function (id) { + switch (id) { + case "sigmund": return function sigmund (obj) { + return JSON.stringify(obj) + } + case "path": return { basename: function (f) { + f = f.split(/[\/\\]/) + var e = f.pop() + if (!e) e = f.pop() + return e + }} + case "lru-cache": return function LRUCache () { + // not quite an LRU, but still space-limited. + var cache = {} + var cnt = 0 + this.set = function (k, v) { + cnt ++ + if (cnt >= 100) cache = {} + cache[k] = v + } + this.get = function (k) { return cache[k] } + } + } + } +} + +minimatch.Minimatch = Minimatch + +var LRU = require("lru-cache") + , cache = minimatch.cache = new LRU({max: 100}) + , GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} + , sigmund = require("sigmund") + +var path = require("path") + // any single thing other than / + // don't need to escape / when using new RegExp() + , qmark = "[^/]" + + // * => any number of characters + , star = qmark + "*?" + + // ** when dots are allowed.

Items are not pro-actively pruned out + as they age, but if you try to get an item that is too old, it'll + drop it and return undefined instead of giving it to you. +* `length` Function that is used to calculate the length of stored + items.

The default is + `function(n){return 1}`, which is fine if you want to store `n` + like-sized things. +* `dispose` Function that is called on items when they are dropped + from the cache. This can be handy if you want to close file + descriptors or do other cleanup tasks when items are no longer + accessible. Called with `key, value`. It's called *before* + actually removing the item from the internal cache, so if you want + to immediately put it back in, you'll have to do that in a + `nextTick` or `setTimeout` callback or it won't do anything. +* `stale` By default, if you set a `maxAge`, it'll only actually pull + stale items out of the cache when you `get(key)`. (That is, it's + not pre-emptively doing a `setTimeout` or anything.) If you set + `stale:true`, it'll return the stale value before deleting it.

Just with one string! + +``` javascript +require('js-yaml'); + +// Get document, or throw exception on error +try { + var doc = require('/home/ixti/example.yml'); + console.log(doc); +} catch (e) { + console.log(e); +} +``` + + +### load (string [ , options ]) + +Parses `string` as single YAML document.

The action keyword argument specifies how the command-line arguments +should be handled. The supported actions are: + +- ```store``` - Just stores the argument’s value. This is the default action. +- ```storeConst``` - Stores value, specified by the const keyword argument. + (Note that the const keyword argument defaults to the rather unhelpful None.) + The 'storeConst' action is most commonly used with optional arguments, that + specify some sort of flag. +- ```storeTrue``` and ```storeFalse``` - Stores values True and False + respectively. These are special cases of 'storeConst'. +- ```append``` - Stores a list, and appends each argument value to the list. + This is useful to allow an option to be specified multiple times. +- ```appendConst``` - Stores a list, and appends value, specified by the + const keyword argument to the list. (Note, that the const keyword argument defaults + is None.) The 'appendConst' action is typically used when multiple arguments need + to store constants to the same list. +- ```count``` - Counts the number of times a keyword argument occurs. For example, + used for increasing verbosity levels. +- ```help``` - Prints a complete help message for all the options in the current + parser and then exits. By default a help action is automatically added to the parser. + See ArgumentParser for details of how the output is created. +- ```version``` - Prints version information and exit. Expects a `version=` + keyword argument in the addArgument() call. + +Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action) + + +Sub-commands +============ + +ArgumentParser.addSubparsers() + +Many programs split their functionality into a number of sub-commands, for +example, the svn program can invoke sub-commands like `svn checkout`, `svn update`, +and `svn commit`. Splitting up functionality this way can be a particularly good +idea when a program performs several different functions which require different +kinds of command-line arguments. `ArgumentParser` supports creation of such +sub-commands with `addSubparsers()` method. The `addSubparsers()` method is +normally called with no arguments and returns an special action object. +This object has a single method `addParser()`, which takes a command name and +any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object +that can be modified as usual. + +Example: + +sub_commands.js +```javascript +#!/usr/bin/env node +'use strict'; + +var ArgumentParser = require('../lib/argparse').ArgumentParser; +var parser = new ArgumentParser({ + version: '0.0.1', + addHelp:true, + description: 'Argparse examples: sub-commands', +}); + +var subparsers = parser.addSubparsers({ + title:'subcommands', + dest:"subcommand_name" +}); + +var bar = subparsers.addParser('c1', {addHelp:true}); +bar.addArgument( + [ '-f', '--foo' ], + { + action: 'store', + help: 'foo3 bar3' + } +); +var bar = subparsers.addParser( + 'c2', + {aliases:['co'], addHelp:true} +); +bar.addArgument( + [ '-b', '--bar' ], + { + action: 'store', + type: 'int', + help: 'foo3 bar3' + } +); + +var args = parser.parseArgs(); +console.dir(args); + +``` + +Details in [original sub-commands guide](http://docs.python.org/dev/library/argparse.html#sub-commands) + + +Contributors +============ + +- [Eugene Shkuropat](https://github.com/shkuropat) +- [Paul Jacobson](https://github.com/hpaulj) + +[others](https://github.com/nodeca/argparse/graphs/contributors) + +License +======= + +Copyright (c) 2012 [Vitaly Puzrin](https://github.com/puzrin). +Released under the MIT license.
