-# Async.js
-
-Async is a utility module which provides straight-forward, powerful functions
-for working with asynchronous JavaScript. 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

-
-## In the Browser
-
-So far it's been tested in IE6, IE7, IE8, FF3.6 and Chrome 5. Usage:
-
-```html
-<script type="text/javascript" src="async.js"></script>
-<script type="text/javascript">
-
- async.map(data, asyncProcess, function(err, results){
- alert(results);
- });
-
-</script>

-<a name="forEach" />
-<a name="each" />
-### 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 the iterator passes an error to this callback, the main
-callback for the each function is immediately called with the error.
-
-Note, that since this function applies the iterator to each item in parallel
-there is no guarantee that the iterator functions will complete in order.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err) which must be called once it has
- completed. If no error has occured, the callback should be run without
- arguments or with an explicit null argument.
-* callback(err) - A callback which is called after all the iterator functions
- have finished, or an error has occurred.
-
-__Example__
-
-```js
-// assuming openFiles is an array of file names and saveFile is a function
-// to save the modified contents of that file:
-
-async.each(openFiles, saveFile, function(err){
- // if any of the saves produced an error, err would equal that error
-});
-```
-
----------------------------------------
-
-<a name="forEachSeries" />
-<a name="eachSeries" />
-### eachSeries(arr, iterator, callback)
-
-The same as each 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. This means the iterator functions will complete in order.
-
-
----------------------------------------
-
-<a name="forEachLimit" />
-<a name="eachLimit" />
-### eachLimit(arr, limit, iterator, callback)
-
-The same as each only no more than "limit" iterators will be simultaneously
-running at any time.
-
-Note that the items are not processed in batches, so there is no guarantee that
- the first "limit" iterator functions will complete before any others are
-started.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* limit - The maximum number of iterators to run at any time.
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err) which must be called once it has
- completed. If no error has occured, the callback should be run without
- arguments or with an explicit null argument.
-* callback(err) - A callback which is called after all the iterator functions
- have finished, or an error has occurred.
-
-__Example__
-
-```js
-// Assume documents is an array of JSON objects and requestApi is a
-// function that interacts with a rate-limited REST api.
-
-async.eachLimit(documents, 20, requestApi, function(err){
- // if any of the saves produced an error, err would equal that error
-});
-```
-
----------------------------------------
-
-<a name="map" />
-### map(arr, iterator, callback)
-
-Produces a new array of values by mapping each value in the given array through
-the iterator function. The iterator is called with an item from the array and a
-callback for when it has finished processing. The callback takes 2 arguments,
-an error and the transformed item from the array. If the iterator passes an
-error to this callback, the main callback for the map function is immediately
-called with the error.
-
-Note, that since this function applies the iterator to each item in parallel
-there is no guarantee that the iterator functions will complete in order, however
-the results array will be in the same order as the original array.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err, transformed) which must be called once
- it has completed with an error (which can be null) and a transformed item.
-* callback(err, results) - A callback which is called after all the iterator
- functions have finished, or an error has occurred. Results is an array of the
- transformed items from the original array.
-
-__Example__
-
-```js
-async.map(['file1','file2','file3'], fs.stat, function(err, results){
- // results is now an array of stats for each file
-});
-```
-
----------------------------------------
-
-<a name="mapSeries" />
-### mapSeries(arr, iterator, callback)
-
-The same as map 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.
-
-
----------------------------------------
-
-<a name="mapLimit" />
-### mapLimit(arr, limit, iterator, callback)
-
-The same as map only no more than "limit" iterators will be simultaneously
-running at any time.
-
-Note that the items are not processed in batches, so there is no guarantee that
- the first "limit" iterator functions will complete before any others are
-started.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* limit - The maximum number of iterators to run at any time.
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err, transformed) which must be called once
- it has completed with an error (which can be null) and a transformed item.
-* callback(err, results) - A callback which is called after all the iterator
- functions have finished, or an error has occurred. Results is an array of the
- transformed items from the original array.
-
-__Example__
-
-```js
-async.mapLimit(['file1','file2','file3'], 1, fs.stat, function(err, results){
- // results is now an array of stats for each file
-});
-```
-
----------------------------------------
-
-<a name="filter" />
-### filter(arr, iterator, callback)
-
-__Alias:__ select
-
-Returns a new array of all the values which pass an async truth test.
-_The callback for each iterator call only accepts a single argument of true or
-false, it does not accept an error argument first!_ This is in-line with the
-way node libraries work with truth tests like fs.exists. This operation is
-performed in parallel, but the results array will be in the same order as the
-original.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A truth test to apply to each item in the array.
- The iterator is passed a callback(truthValue) which must be called with a
- boolean argument once it has completed.
-* callback(results) - A callback which is called after all the iterator
- functions have finished.
-
-__Example__
-
-```js
-async.filter(['file1','file2','file3'], fs.exists, function(results){
- // results now equals an array of the existing files
-});
-```
-
----------------------------------------
-
-<a name="filterSeries" />
-### filterSeries(arr, iterator, callback)
-
-__alias:__ selectSeries
-
-The same as filter 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.
-
----------------------------------------
-
-<a name="reject" />
-### reject(arr, iterator, callback)
-
-The opposite of filter. Removes values that pass an async truth test.
-
----------------------------------------
-
-<a name="rejectSeries" />
-### rejectSeries(arr, iterator, callback)
-
-The same as reject, only the iterator is applied to each item in the array
-in series.
-
-
----------------------------------------
-
-<a name="reduce" />
-### reduce(arr, memo, iterator, callback)
-
-__aliases:__ inject, foldl
-
-Reduces a list of values into a single value using an async iterator to return
-each successive step. Memo is the initial state of the reduction. This
-function only operates in series. For performance reasons, it may make sense to
-split a call to this function into a parallel map, then use the normal
-Array.prototype.reduce on the results. This function is for situations where
-each step in the reduction needs to be async, if you can get the data before
-reducing it then it's probably a good idea to do so.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* memo - The initial state of the reduction.
-* iterator(memo, item, callback) - A function applied to each item in the
- array to produce the next step in the reduction. The iterator is passed a
- callback(err, reduction) which accepts an optional error as its first
- argument, and the state of the reduction as the second. If an error is
- passed to the callback, the reduction is stopped and the main callback is
- immediately called with the error.
-* callback(err, result) - A callback which is called after all the iterator
- functions have finished. Result is the reduced value.
-
-__Example__
-
-```js
-async.reduce([1,2,3], 0, function(memo, item, callback){
- // pointless async:
- process.nextTick(function(){
- callback(null, memo + item)
- });
-}, function(err, result){
- // result is now equal to the last value of memo, which is 6
-});
-```
-
----------------------------------------
-
-<a name="reduceRight" />
-### reduceRight(arr, memo, iterator, callback)
-
-__Alias:__ foldr
-
-Same as reduce, only operates on the items in the array in reverse order.
-
-
----------------------------------------
-
-<a name="detect" />
-### detect(arr, iterator, callback)
-
-Returns the first value in a list that passes an async truth test. The
-iterator is applied in parallel, meaning the first iterator to return true will
-fire the detect callback with that result. That means the result might not be
-the first item in the original array (in terms of order) that passes the test.
-
-If order within the original array is important then look at detectSeries.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A truth test to apply to each item in the array.
- The iterator is passed a callback(truthValue) which must be called with a
- boolean argument once it has completed.
-* callback(result) - A callback which is called as soon as any iterator returns
- true, or after all the iterator functions have finished. Result will be
- the first item in the array that passes the truth test (iterator) or the
- value undefined if none passed.
-
-__Example__
-
-```js
-async.detect(['file1','file2','file3'], fs.exists, function(result){
- // result now equals the first file in the list that exists
-});
-```
-
----------------------------------------
-
-<a name="detectSeries" />
-### detectSeries(arr, iterator, callback)
-
-The same as detect, only the iterator is applied to each item in the array
-in series. This means the result is always the first in the original array (in
-terms of array order) that passes the truth test.
-
-
----------------------------------------
-
-<a name="sortBy" />
-### sortBy(arr, iterator, callback)
-
-Sorts a list by the results of running each value through an async iterator.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err, sortValue) which must be called once it
- has completed with an error (which can be null) and a value to use as the sort
- criteria.
-* callback(err, results) - A callback which is called after all the iterator
- functions have finished, or an error has occurred. Results is the items from
- the original array sorted by the values returned by the iterator calls.
-
-__Example__
-
-```js
-async.sortBy(['file1','file2','file3'], function(file, callback){
- fs.stat(file, function(err, stats){
- callback(err, stats.mtime);
- });
-}, function(err, results){
- // results is now the original array of files sorted by
- // modified date
-});
-```
-
----------------------------------------
-
-<a name="some" />
-### some(arr, iterator, callback)
-
-__Alias:__ any
-
-Returns true if at least one element in the array satisfies an async test.
-_The callback for each iterator call only accepts a single argument of true or
-false, it does not accept an error argument first!_ This is in-line with the
-way node libraries work with truth tests like fs.exists. Once any iterator
-call returns true, the main callback is immediately called.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A truth test to apply to each item in the array.
- The iterator is passed a callback(truthValue) which must be called with a
- boolean argument once it has completed.
-* callback(result) - A callback which is called as soon as any iterator returns
- true, or after all the iterator functions have finished. Result will be
- either true or false depending on the values of the async tests.
-
-__Example__
-
-```js
-async.some(['file1','file2','file3'], fs.exists, function(result){
- // if result is true then at least one of the files exists
-});
-```
-
----------------------------------------
-
-<a name="every" />
-### every(arr, iterator, callback)
-
-__Alias:__ all
-
-Returns true if every element in the array satisfies an async test.
-_The callback for each iterator call only accepts a single argument of true or
-false, it does not accept an error argument first!_ This is in-line with the
-way node libraries work with truth tests like fs.exists.
-
-__Arguments__
-
-* arr - An array to iterate over.
-* iterator(item, callback) - A truth test to apply to each item in the array.
- The iterator is passed a callback(truthValue) which must be called with a
- boolean argument once it has completed.
-* callback(result) - A callback which is called after all the iterator
- functions have finished. Result will be either true or false depending on
- the values of the async tests.
-
-__Example__
-
-```js
-async.every(['file1','file2','file3'], fs.exists, function(result){
- // if result is true then every file exists
-});
-```
-
----------------------------------------
-
-<a name="concat" />
-### concat(arr, iterator, callback)
-
-Applies an iterator to each item in a list, concatenating the results. Returns the
-concatenated list. The iterators are called in parallel, and the results are
-concatenated as they return. There is no guarantee that the results array will
-be returned in the original order of the arguments passed to the iterator function.
-
-__Arguments__
-
-* arr - An array to iterate over
-* iterator(item, callback) - A function to apply to each item in the array.
- The iterator is passed a callback(err, results) which must be called once it
- has completed with an error (which can be null) and an array of results.
-* callback(err, results) - A callback which is called after all the iterator
- functions have finished, or an error has occurred. Results is an array containing
- the concatenated results of the iterator function.
-
-__Example__
-
-```js
-async.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files){
- // files is now a list of filenames that exist in the 3 directories
-});
-```
-
----------------------------------------
-
-<a name="concatSeries" />
-### concatSeries(arr, iterator, callback)
-
-Same as async.concat, but executes in series instead of parallel.
-
-
-## Control Flow
-
-<a name="series" />
-### series(tasks, [callback])
-
-Run an array of functions in series, each one running once the previous
-function has completed. If any functions in the series pass an error to its
-callback, no more functions are run and the callback for the series is
-immediately called with the value of the error. Once the tasks have completed,
-the results are passed to the final callback as an array.
-
-It is also possible to use an object instead of an array. Each property will be
-run as a function and the results will be passed to the final callback as an object
-instead of an array. This can be a more readable way of handling results from
-async.series.
-
-
-__Arguments__
-
-* tasks - An array or object containing functions to run, each function is passed
- a callback(err, result) it must call on completion with an error (which can
- be null) and an optional result value.
-* callback(err, results) - An optional callback to run once all the functions
- have completed. This function gets a results array (or object) containing all
- the result arguments passed to the task callbacks.
-
-__Example__
-
-```js
-async.series([
- function(callback){
- // do some stuff ...
- callback(null, 'one');
- },
- function(callback){
- // do some more stuff ...
- callback(null, 'two');
- }
-],
-// optional callback
-function(err, results){
- // results is now equal to ['one', 'two']
-});
-
-
-// an example using an object instead of an array
-async.series({
- one: function(callback){
- setTimeout(function(){
- callback(null, 1);
- }, 200);
- },
- two: function(callback){
- setTimeout(function(){
- callback(null, 2);
- }, 100);
- }
-},
-function(err, results) {
- // results is now equal to: {one: 1, two: 2}
-});
-```
-
----------------------------------------
-
-<a name="parallel" />
-### parallel(tasks, [callback])
-
-Run an array of functions in parallel, without waiting until the previous
-function has completed. If any of the functions pass an error to its
-callback, the main callback is immediately called with the value of the error.
-Once the tasks have completed, the results are passed to the final callback as an
-array.
-
-It is also possible to use an object instead of an array. Each property will be
-run as a function and the results will be passed to the final callback as an object
-instead of an array. This can be a more readable way of handling results from
-async.parallel.
-
-
-__Arguments__
-
-* tasks - An array or object containing functions to run, each function is passed
- a callback(err, result) it must call on completion with an error (which can
- be null) and an optional result value.
-* callback(err, results) - An optional callback to run once all the functions
- have completed. This function gets a results array (or object) containing all
- the result arguments passed to the task callbacks.
-
-__Example__
-
-```js
-async.parallel([
- function(callback){
- setTimeout(function(){
- callback(null, 'one');
- }, 200);
- },
- function(callback){
- setTimeout(function(){
- callback(null, 'two');
- }, 100);
- }
-],
-// optional callback
-function(err, results){
- // the results array will equal ['one','two'] even though
- // the second function had a shorter timeout.
-});
-
-
-// an example using an object instead of an array
-async.parallel({
- one: function(callback){
- setTimeout(function(){
- callback(null, 1);
- }, 200);
- },
- two: function(callback){
- setTimeout(function(){
- callback(null, 2);
- }, 100);
- }
-},
-function(err, results) {
- // results is now equals to: {one: 1, two: 2}
-});
-```
-
----------------------------------------
-
-<a name="parallel" />
-### parallelLimit(tasks, limit, [callback])
-
-The same as parallel only the tasks are executed in parallel with a maximum of "limit"
-tasks executing at any time.
-
-Note that the tasks are not executed in batches, so there is no guarantee that
-the first "limit" tasks will complete before any others are started.
-
-__Arguments__
-
-* tasks - An array or object containing functions to run, each function is passed
- a callback(err, result) it must call on completion with an error (which can
- be null) and an optional result value.
-* limit - The maximum number of tasks to run at any time.
-* callback(err, results) - An optional callback to run once all the functions
- have completed. This function gets a results array (or object) containing all
- the result arguments passed to the task callbacks.
-
----------------------------------------
-
-<a name="whilst" />
-### whilst(test, fn, callback)
-
-Repeatedly call fn, while test returns true. Calls the callback when stopped,
-or an error occurs.
-
-__Arguments__
-
-* test() - synchronous truth test to perform before each execution of fn.
-* fn(callback) - A function to call each time the test passes. The function is
- passed a callback(err) which must be called once it has completed with an
- optional error argument.
-* callback(err) - A callback which is called after the test fails and repeated
- execution of fn has stopped.
-
-__Example__
-
-```js
-var count = 0;
-
-async.whilst(
- function () { return count < 5; },
- function (callback) {
- count++;
- setTimeout(callback, 1000);
- },
- function (err) {
- // 5 seconds have passed
- }
-);
-```
-
----------------------------------------
-
-<a name="doWhilst" />
-### doWhilst(fn, test, callback)
-
-The post check version of whilst. To reflect the difference in the order of operations `test` and `fn` arguments are switched. `doWhilst` is to `whilst` as `do while` is to `while` in plain JavaScript.
-
----------------------------------------
-
-<a name="until" />
-### until(test, fn, callback)
-
-Repeatedly call fn, until test returns true. Calls the callback when stopped,
-or an error occurs.
-
-The inverse of async.whilst.
-
----------------------------------------
-
-<a name="doUntil" />
-### doUntil(fn, test, callback)
-
-Like doWhilst except the test is inverted. Note the argument ordering differs from `until`.
-
----------------------------------------
-
-<a name="forever" />
-### forever(fn, callback)
-
-Calls the asynchronous function 'fn' repeatedly, in series, indefinitely.
-If an error is passed to fn's callback then 'callback' is called with the
-error, otherwise it will never be called.
-
----------------------------------------
-
-<a name="waterfall" />
-### waterfall(tasks, [callback])
-
-Runs an array of functions in series, each passing their results to the next in
-the array. However, if any of the functions pass an error to the callback, the
-next function is not executed and the main callback is immediately called with
-the error.
-
-__Arguments__
-
-* tasks - An array of functions to run, each function is passed a
- callback(err, result1, result2, ...) it must call on completion. The first
- argument is an error (which can be null) and any further arguments will be
- passed as arguments in order to the next task.
-* callback(err, [results]) - An optional callback to run once all the functions
- have completed. This will be passed the results of the last task's callback.
-
-
-
-__Example__
-
-```js
-async.waterfall([
- function(callback){
- callback(null, 'one', 'two');
- },
- function(arg1, arg2, callback){
- callback(null, 'three');
- },
- function(arg1, callback){
- // arg1 now equals 'three'
- callback(null, 'done');
- }
-], function (err, result) {
- // result now equals 'done'
-});
-```
-
----------------------------------------
-<a name="compose" />
-### compose(fn1, fn2...)
-
-Creates a function which is a composition of the passed asynchronous
-functions. Each function consumes the return value of the function that
-follows. Composing functions f(), g() and h() would produce the result of
-f(g(h())), only this version uses callbacks to obtain the return values.
-
-Each function is executed with the `this` binding of the composed function.
-
-__Arguments__
-
-* functions... - the asynchronous functions to compose
-
-
-__Example__
-
-```js
-function add1(n, callback) {
- setTimeout(function () {
- callback(null, n + 1);
- }, 10);
-}
-
-function mul3(n, callback) {
- setTimeout(function () {
- callback(null, n * 3);
- }, 10);
-}
-
-var add1mul3 = async.compose(mul3, add1);
-
-add1mul3(4, function (err, result) {
- // result now equals 15
-});
-```
-
----------------------------------------
-<a name="applyEach" />
-### applyEach(fns, args..., callback)
-
-Applies the provided arguments to each function in the array, calling the
-callback after all functions have completed. If you only provide the first
-argument then it will return a function which lets you pass in the
-arguments as if it were a single function call.
-
-__Arguments__
-
-* fns - the asynchronous functions to all call with the same arguments
-* args... - any number of separate arguments to pass to the function
-* callback - the final argument should be the callback, called when all
- functions have completed processing
-
-
-__Example__
-
-```js
-async.applyEach([enableSearch, updateSchema], 'bucket', callback);
-
-// partial application example:
-async.each(
- buckets,
- async.applyEach([enableSearch, updateSchema]),
- callback
-);
-```
-
----------------------------------------
-
-<a name="applyEachSeries" />
-### applyEachSeries(arr, iterator, callback)
-
-The same as applyEach only the functions are applied in series.
-
----------------------------------------
-
-<a name="queue" />
-### queue(worker, concurrency)
-
-Creates a queue object with the specified concurrency. Tasks added to the
-queue will be processed in parallel (up to the concurrency limit). If all
-workers are in progress, the task is queued until one is available. Once
-a worker has completed a task, the task's callback is called.
-
-__Arguments__
-
-* worker(task, callback) - An asynchronous function for processing a queued
- task, which must call its callback(err) argument when finished, with an
- optional error as an argument.
-* concurrency - An integer for determining how many worker functions should be
- run in parallel.
-
-__Queue objects__
-
-The queue object returned by this function has the following properties and
-methods:
-
-* length() - a function returning the number of items waiting to be processed.
-* concurrency - an integer for determining how many worker functions should be
- run in parallel. This property can be changed after a queue is created to
- alter the concurrency on-the-fly.
-* push(task, [callback]) - add a new task to the queue, the callback is called
- once the worker has finished processing the task.
- instead of a single task, an array of tasks can be submitted. the respective callback is used for every task in the list.
-* unshift(task, [callback]) - add a new task to the front of the queue.
-* saturated - a callback that is called when the queue length hits the concurrency and further tasks will be queued
-* empty - a callback that is called when the last item from the queue is given to a worker
-* drain - a callback that is called when the last item from the queue has returned from the worker
-
-__Example__
-
-```js
-// create a queue object with concurrency 2
-
-var q = async.queue(function (task, callback) {
- console.log('hello ' + task.name);
- callback();
-}, 2);
-
-
-// assign a callback
-q.drain = function() {
- console.log('all items have been processed');
-}
-
-// add some items to the queue
-
-q.push({name: 'foo'}, function (err) {
- console.log('finished processing foo');
-});
-q.push({name: 'bar'}, function (err) {
- console.log('finished processing bar');
-});
-
-// add some items to the queue (batch-wise)
-
-q.push([{name: 'baz'},{name: 'bay'},{name: 'bax'}], function (err) {
- console.log('finished processing bar');
-});
-
-// add some items to the front of the queue
-
-q.unshift({name: 'bar'}, function (err) {
- console.log('finished processing bar');
-});
-```
-
----------------------------------------
-
-<a name="cargo" />
-### cargo(worker, [payload])
-
-Creates a cargo object with the specified payload. Tasks added to the
-cargo will be processed altogether (up to the payload limit). If the
-worker is in progress, the task is queued until it is available. Once
-the worker has completed some tasks, each callback of those tasks is called.
-
-__Arguments__
-
-* worker(tasks, callback) - An asynchronous function for processing an array of
- queued tasks, which must call its callback(err) argument when finished, with
- an optional error as an argument.
-* payload - An optional integer for determining how many tasks should be
- processed per round; if omitted, the default is unlimited.
-
-__Cargo objects__
-
-The cargo object returned by this function has the following properties and
-methods:
-
-* length() - a function returning the number of items waiting to be processed.
-* payload - an integer for determining how many tasks should be
- process per round. This property can be changed after a cargo is created to
- alter the payload on-the-fly.
-* push(task, [callback]) - add a new task to the queue, the callback is called
- once the worker has finished processing the task.
- instead of a single task, an array of tasks can be submitted. the respective callback is used for every task in the list.
-* saturated - a callback that is called when the queue length hits the concurrency and further tasks will be queued
-* empty - a callback that is called when the last item from the queue is given to a worker
-* drain - a callback that is called when the last item from the queue has returned from the worker
-
-__Example__
-
-```js
-// create a cargo object with payload 2
-
-var cargo = async.cargo(function (tasks, callback) {
- for(var i=0; i<tasks.length; i++){
- console.log('hello ' + tasks[i].name);
- }
- callback();
-}, 2);
-
-
-// add some items
-
-cargo.push({name: 'foo'}, function (err) {
- console.log('finished processing foo');
-});
-cargo.push({name: 'bar'}, function (err) {
- console.log('finished processing bar');
-});
-cargo.push({name: 'baz'}, function (err) {
- console.log('finished processing baz');
-});
-```
-
----------------------------------------
-
-<a name="auto" />
-### auto(tasks, [callback])
-
-Determines the best order for running functions based on their requirements.
-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, 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.
-
-
----------------------------------------
-
-<a name="iterator" />
-### 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'
-```
-
----------------------------------------
-
-<a name="apply" />
-### 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
-```
-
----------------------------------------
-
-<a name="nextTick" />
-### 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')
-```
-
-<a name="times" />
-### 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
-});
-```
-
-<a name="timesSeries" />
-### 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
-
-<a name="memoize" />
-### 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
-});
-```
-
-<a name="unmemoize" />
-### unmemoize(fn)
-
-Undoes a memoized function, reverting it to the original, unmemoized
-form. Comes handy in tests.
-
-__Arguments__
-
-* fn - the memoized function
-
-<a name="log" />
-### 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'
-```
-
----------------------------------------
-
-<a name="dir" />
-### 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'}
-```
-
----------------------------------------
-
-<a name="noConflict" />
-### noConflict()
-
-Changes the value of async back to its original value, returning a reference to the
-async object.

-Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
-
-It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

-## Examples
-
-### Parallel Jobs
-
-Runs iterator over provided array in parallel. Stores output in the `result` array,
-on the matching positions. In unlikely event of an error from one of the jobs,
-will terminate rest of the active jobs (if abort function is provided)
-and return error along with salvaged data to the main callback function.
-
-#### Input Array
-
-```javascript
-var parallel = require('asynckit').parallel
- , assert = require('assert')
- ;
-
-var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
- , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
- , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
- , target = []
- ;
-
-parallel(source, asyncJob, function(err, result)
-{
- assert.deepEqual(result, expectedResult);
- assert.deepEqual(target, expectedTarget);
-});
-
-// async job accepts one element from the array
-// and a callback function
-function asyncJob(item, cb)
-{
- // different delays (in ms) per item
- var delay = item * 25;
-
- // pretend different jobs take different time to finish
- // and not in consequential order
- var timeoutId = setTimeout(function() {
- target.push(item);
- cb(null, item * 2);
- }, delay);
-
- // allow to cancel "leftover" jobs upon error
- // return function, invoking of which will abort this job
- return clearTimeout.bind(null, timeoutId);
-}
-```
-
-More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
-
-#### Input Object
-
-Also it supports named jobs, listed via object.
-
-```javascript
-var parallel = require('asynckit/parallel')
- , assert = require('assert')
- ;
-
-var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
- , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
- , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
- , expectedKeys = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
- , target = []
- , keys = []
- ;
-
-parallel(source, asyncJob, function(err, result)
-{
- assert.deepEqual(result, expectedResult);
- assert.deepEqual(target, expectedTarget);
- assert.deepEqual(keys, expectedKeys);
-});
-
-// supports full value, key, callback (shortcut) interface
-function asyncJob(item, key, cb)
-{
- // different delays (in ms) per item
- var delay = item * 25;
-
- // pretend different jobs take different time to finish
- // and not in consequential order
- var timeoutId = setTimeout(function() {
- keys.push(key);
- target.push(item);
- cb(null, item * 2);
- }, delay);
-
- // allow to cancel "leftover" jobs upon error
- // return function, invoking of which will abort this job
- return clearTimeout.bind(null, timeoutId);

-
-### Serial Jobs
-
-Runs iterator over provided array sequentially. Stores output in the `result` array,
-on the matching positions. In unlikely event of an error from one of the jobs,
-will not proceed to the rest of the items in the list
-and return error along with salvaged data to the main callback function.
-
-#### Input Array
-
-```javascript
-var serial = require('asynckit/serial')
- , assert = require('assert')
- ;
-
-var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
- , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
- , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
- , target = []
- ;
-
-serial(source, asyncJob, function(err, result)
-{
- assert.deepEqual(result, expectedResult);
- assert.deepEqual(target, expectedTarget);
-});
-
-// extended interface (item, key, callback)
-// also supported for arrays
-function asyncJob(item, key, cb)
-{
- target.push(key);
-
- // it will be automatically made async
- // even it iterator "returns" in the same event loop
- cb(null, item * 2);

-_Note: Since _object_ is an _unordered_ collection of properties,
-it may produce unexpected results with sequential iterations.
-Whenever order of the jobs' execution is important please use `serialOrdered` method._

-### Ordered Serial Iterations
-
-TBD
-
-For example [compare-property](compare-property) package.
-
-### Streaming interface
