# Contributing to jQuery
1. [Getting Involved](#getting-involved)
2. [Questions and Discussion](#questions-and-discussion)
3. [How To Report Bugs](#how-to-report-bugs)
4. [Tips for Bug Patching](#tips-for-bug-patching)
Note: This is the code development repository for *jQuery Core* only. Before opening an issue or making a pull request, be sure you're in the right place.
* jQuery plugin issues should be reported to the author of the plugin.
* jQuery Core API documentation issues can be filed [at the API repo](http://github.com/jquery/api.jquery.com/issues).
* Bugs or suggestions for other jQuery Foundation projects should be filed in [their respective repos](http://github.com/jquery/).
## Getting Involved
We've put together [a short guide with tips, tricks, and ideas on getting started](http://contribute.jquery.org/open-source/). We're always looking for help identifying bugs, writing and reducing test cases, and documentation.
More information on how to contribute to this and other jQuery Foundation projects is at [contribute.jquery.org](http://contribute.jquery.org). Please review our [commit & pull request guide](http://contribute.jquery.org/commits-and-pull-requests/) and [style guides](http://contribute.jquery.org/style-guide/) for instructions on how to maintain a fork and submit patches. Before we can merge any pull request, we'll also need you to sign our [contributor license agreement](http://contribute.jquery.org/cla/).
## Questions and Discussion
### Forum and IRC
jQuery is so popular that many developers have knowledge of its capabilities and limitations. Most questions about using jQuery can be answered on popular forums such as [Stack Overflow](http://stackoverflow.com). Please start there when you have questions, even if you think you've found a bug.
The jQuery Core team watches the [jQuery Development Forum](http://forum.jquery.com/developing-jquery-core). If you have longer posts or questions that can't be answered in places such as Stack Overflow, please feel free to post them there. If you think you've found a bug, please [file it in the bug tracker](#how-to-report-bugs). The Core team can be found in the [#jquery-dev](http://webchat.freenode.net/?channels=jquery-dev) IRC channel on irc.freenode.net.
### Weekly Status Meetings
The jQuery Core team has a weekly meeting to discuss the progress of current work. The meeting is held in the [#jquery-meeting](http://webchat.freenode.net/?channels=jquery-meeting) IRC channel on irc.freenode.net at [Noon EST](http://www.timeanddate.com/worldclock/fixedtime.html?month=1&day=17&year=2011&hour=12&min=0&sec=0&p1=43) on Mondays.
[jQuery Core Meeting Notes](http://meetings.jquery.org/category/core/)
## How to Report Bugs
### Make sure it is a jQuery bug
Most bugs reported to our bug tracker are actually bugs in user code, not in jQuery code. Keep in mind that just because your code throws an error inside of jQuery, this does *not* mean the bug is a jQuery bug.
Ask for help first in the [Using jQuery Forum](http://forum.jquery.com/using-jquery) or another discussion forum like [Stack Overflow](http://stackoverflow.com/). You will get much quicker support, and you will help avoid tying up the jQuery team with invalid bug reports.
### Disable browser extensions
Make sure you have reproduced the bug with all browser extensions and add-ons disabled, as these can sometimes cause things to break in interesting and unpredictable ways. Try using incognito, stealth or anonymous browsing modes.
### Try the latest version of jQuery
Bugs in old versions of jQuery may have already been fixed. In order to avoid reporting known issues, make sure you are always testing against the [latest build](http://code.jquery.com/jquery.js). We cannot fix bugs in older released files, if a bug has been fixed in a subsequent version of jQuery the site should upgrade.
### Simplify the test case
When experiencing a problem, [reduce your code](http://webkit.org/quality/reduction.html) to the bare minimum required to reproduce the issue. This makes it *much* easier to isolate and fix the offending code. Bugs reported without reduced test cases take on average 9001% longer to fix than bugs that are submitted with them, so you really should try to do this if at all possible.
### Search for related or duplicate issues
Go to the [jQuery Core issue tracker](https://github.com/jquery/jquery/issues) and make sure the problem hasn't already been reported. If not, create a new issue there and include your test case.
## Tips For Bug Patching
We *love* when people contribute back to the project by patching the bugs they find. Since jQuery is used by so many people, we are cautious about the patches we accept and want to be sure they don't have a negative impact on the millions of people using jQuery each day. For that reason it can take a while for any suggested patch to work its way through the review and release process. The reward for you is knowing that the problem you fixed will improve things for millions of sites and billions of visits per day.
### Build a Local Copy of jQuery
Create a fork of the jQuery repo on github at http://github.com/jquery/jquery
Change directory to your web root directory, whatever that might be:
```bash
$ cd /path/to/your/www/root/
```
Clone your jQuery fork to work locally
```bash
$ git clone git@github.com:username/jquery.git
```
Change directory to the newly created dir jquery/
```bash
$ cd jquery
```
Add the jQuery master as a remote. I label mine "upstream"
```bash
$ git remote add upstream git://github.com/jquery/jquery.git
```
Get in the habit of pulling in the "upstream" master to stay up to date as jQuery receives new commits
```bash
$ git pull upstream master
```
Run the build script
```bash
$ npm run build
```
Run the Grunt tools:
```bash
$ grunt && grunt watch
```
Now open the jQuery test suite in a browser at http://localhost/test. If there is a port, be sure to include it.
Success! You just built and tested jQuery!
### Test Suite Tips...
During the process of writing your patch, you will run the test suite MANY times. You can speed up the process by narrowing the running test suite down to the module you are testing by either double clicking the title of the test or appending it to the url. The following examples assume you're working on a local repo, hosted on your localhost server.
Example:
http://localhost/test/?filter=css
This will only run the "css" module tests. This will significantly speed up your development and debugging.
**ALWAYS RUN THE FULL SUITE BEFORE COMMITTING AND PUSHING A PATCH!**
### Browser support
Remember that jQuery supports multiple browsers and their versions; any contributed code must work in all of them. You can refer to the [browser support page](http://jquery.com/browser-support/) for the current list of supported browsers.
Note that browser support differs depending on whether you are targeting the `master` or `1.x` branch.

[jQuery](http://jquery.com/) — New Wave JavaScript
==================================================
Contribution Guides
--------------------------------------
In the spirit of open source software development, jQuery always encourages community code contribution. To help you get started and before you jump into writing code, be sure to read these important contribution guidelines thoroughly:
1. [Getting Involved](http://contribute.jquery.org/)
2. [Core Style Guide](http://contribute.jquery.org/style-guide/js/)
3. [Writing Code for jQuery Foundation Projects](http://contribute.jquery.org/code/)
Environments in which to use jQuery
--------------------------------------
- [Browser support](http://jquery.com/browser-support/) differs between the master branch and the 1.x branch. Specifically, the master branch does not support legacy browsers such as IE6-8. The jQuery team continues to provide support for legacy browsers on the 1.x branch. Use the latest 1.x release if support for those browsers is required. See [browser support](http://jquery.com/browser-support/) for more info.
- To use jQuery in Node, browser extensions, and other non-browser environments, use only master branch releases (2.x). The 1.x branch does not support these environments.
What you need to build your own jQuery
--------------------------------------
In order to build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported.
For Windows, you have to download and install [git](http://git-scm.com/downloads) and [Node.js](http://nodejs.org/download/).
OS X users should install [Homebrew](http://brew.sh/). Once Homebrew is installed, run `brew install git` to install git,
and `brew install node` to install Node.js.
Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source
if you swing that way. Easy-peasy.
How to build your own jQuery
----------------------------
Clone a copy of the main jQuery git repo by running:
```bash
git clone git://github.com/jquery/jquery.git
```
Enter the jquery directory and run the build script:
```bash
cd jquery && npm run build
```
The built version of jQuery will be put in the `dist/` subdirectory, along with the minified copy and associated map file.
If you want to create custom build or help with jQuery development, it would be better to install [grunt command line interface](https://github.com/gruntjs/grunt-cli) as a global package:
```
npm install -g grunt-cli
```
Make sure you have `grunt` installed by testing:
```
grunt -V
```
Now by running the `grunt` command, in the jquery directory, you can build a full version of jQuery, just like with an `npm run build` command:
```
grunt
```
There are many other tasks available for jQuery Core:
```
grunt -help
```
### Modules
Special builds can be created that exclude subsets of jQuery functionality.
This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used.
For example, an app that only used JSONP for `$.ajax()` and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules.
Any module may be excluded except for `core`, and `selector`. To exclude a module, pass its path relative to the `src` folder (without the `.js` extension).
Some example modules that can be excluded are:
- **ajax**: All AJAX functionality: `$.ajax()`, `$.get()`, `$.post()`, `$.ajaxSetup()`, `.load()`, transports, and ajax event shorthands such as `.ajaxStart()`.
- **ajax/xhr**: The XMLHTTPRequest AJAX transport only.
- **ajax/script**: The `<script>` AJAX transport only; used to retrieve scripts.
- **ajax/jsonp**: The JSONP AJAX transport only; depends on the ajax/script transport.
- **css**: The `.css()` method plus non-animated `.show()`, `.hide()` and `.toggle()`. Also removes **all** modules depending on css (including **effects**, **dimensions**, and **offset**).
- **deprecated**: Methods documented as deprecated but not yet removed.
- **dimensions**: The `.width()` and `.height()` methods, including `inner-` and `outer-` variations.
- **effects**: The `.animate()` method and its shorthands such as `.slideUp()` or `.hide("slow")`.
- **event**: The `.on()` and `.off()` methods and all event functionality. Also removes `event/alias`.
- **event/alias**: All event attaching/triggering shorthands like `.click()` or `.mouseover()`.
- **event/focusin**: Cross-browser support for the focusin and focusout events.
- **event/trigger**: The `.trigger()` and `.triggerHandler()` methods. Used by **alias** and **focusin** modules.
- **offset**: The `.offset()`, `.position()`, `.offsetParent()`, `.scrollLeft()`, and `.scrollTop()` methods.
- **wrap**: The `.wrap()`, `.wrapAll()`, `.wrapInner()`, and `.unwrap()` methods.
- **core/ready**: Exclude the ready module if you place your scripts at the end of the body. Any ready callbacks bound with `jQuery()` will simply be called immediately. However, `jQuery(document).ready()` will not be a function and `.on("ready", ...)` or similar will not be triggered.
- **deferred**: Exclude jQuery.Deferred. This also removes jQuery.Callbacks. *Note* that modules that depend on jQuery.Deferred(AJAX, effects, core/ready) will not be removed and will still expect jQuery.Deferred to be there. Include your own jQuery.Deferred implementation or exclude those modules as well (`grunt custom:-deferred,-ajax,-effects,-core/ready`).
- **exports/global**: Exclude the attachment of global jQuery variables ($ and jQuery) to the window.
- **exports/amd**: Exclude the AMD definition.
As a special case, you may also replace Sizzle by using a special flag `grunt custom:-sizzle`.
- **sizzle**: The Sizzle selector engine. When this module is excluded, it is replaced by a rudimentary selector engine based on the browser's `querySelectorAll` method that does not support jQuery selector extensions or enhanced semantics. See the [selector-native.js](https://github.com/jquery/jquery/blob/master/src/selector-native.js) file for details.
*Note*: Excluding Sizzle will also exclude all jQuery selector extensions (such as `effects/animatedSelector` and `css/hiddenVisibleSelectors`).
*Note*: Removing Sizzle is not supported on the `1.x` branch.
The build process shows a message for each dependent module it excludes or includes.
##### AMD name
As an option, you can set the module name for jQuery's AMD definition. By default, it is set to "jquery", which plays nicely with plugins and third-party libraries, but there may be cases where you'd like to change this. Simply set the `"amd"` option:
```bash
grunt custom --amd="custom-name"
```
Or, to define anonymously, set the name to an empty string.
```bash
grunt custom --amd=""
```
#### Custom Build Examples
To create a custom build, first check out the version:
```bash
git pull; git checkout VERSION
```
where VERSION is the version you want to customize. Then, make sure all Node dependencies are installed:
```bash
npm install
```
Create the custom build using the `grunt custom` option, listing the modules to be excluded.
Exclude all **ajax** functionality:
```bash
grunt custom:-ajax
```
Excluding **css** removes modules depending on CSS: **effects**, **offset**, **dimensions**.
```bash
grunt custom:-css
```
Exclude a bunch of modules:
```bash
grunt custom:-ajax,-css,-deprecated,-dimensions,-effects,-event/alias,-offset,-wrap
```
For questions or requests regarding custom builds, please start a thread on the [Developing jQuery Core](https://forum.jquery.com/developing-jquery-core) section of the forum. Due to the combinatorics and custom nature of these builds, they are not regularly tested in jQuery's unit test process.
Running the Unit Tests
--------------------------------------
Make sure you have the necessary dependencies:
```bash
npm install
```
Start `grunt watch` or `npm start` to auto-build jQuery as you work:
```bash
grunt watch
```
Run the unit tests with a local server that supports PHP. Ensure that you run the site from the root directory, not the "test" directory. No database is required. Pre-configured php local servers are available for Windows and Mac. Here are some options:
- Windows: [WAMP download](http://www.wampserver.com/en/)
- Mac: [MAMP download](http://www.mamp.info/en/index.html)
- Linux: [Setting up LAMP](https://www.linux.com/learn/tutorials/288158-easy-lamp-server-installation)
- [Mongoose (most platforms)](http://code.google.com/p/mongoose/)
Building to a different directory
---------------------------------
To copy the built jQuery files from `/dist` to another directory:
```bash
grunt && grunt dist:/path/to/special/location/
```
With this example, the output files would be:
```bash
/path/to/special/location/jquery.js
/path/to/special/location/jquery.min.js
```
To add a permanent copy destination, create a file in `dist/` called ".destination.json". Inside the file, paste and customize the following:
```json
{
"/Absolute/path/to/other/destination": true
}
```
Additionally, both methods can be combined.
Essential Git
-------------
As the source code is handled by the Git version control system, it's useful to know some features used.
### Cleaning ###
If you want to purge your working directory back to the status of upstream, the following commands can be used (remember everything you've worked on is gone after these):
```bash
git reset --hard upstream/master
git clean -fdx
```
### Rebasing ###
For feature/topic branches, you should always use the `--rebase` flag to `git pull`, or if you are usually handling many temporary "to be in a github pull request" branches, run the following to automate this:
```bash
git config branch.autosetuprebase local
```
(see `man git-config` for more information)
### Handling merge conflicts ###
If you're getting merge conflicts when merging, instead of editing the conflicted files manually, you can use the feature
`git mergetool`. Even though the default tool `xxdiff` looks awful/old, it's rather useful.
The following are some commands that can be used there:
* `Ctrl + Alt + M` - automerge as much as possible
* `b` - jump to next merge conflict
* `s` - change the order of the conflicted lines
* `u` - undo a merge
* `left mouse button` - mark a block to be the winner
* `middle mouse button` - mark a line to be the winner
* `Ctrl + S` - save
* `Ctrl + Q` - quit
[QUnit](http://api.qunitjs.com) Reference
-----------------
### Test methods ###
```js
expect( numAssertions );
stop();
start();
```
Note: QUnit's eventual addition of an argument to stop/start is ignored in this test suite so that start and stop can be passed as callbacks without worrying about their parameters
### Test assertions ###
```js
ok( value, [message] );
equal( actual, expected, [message] );
notEqual( actual, expected, [message] );
deepEqual( actual, expected, [message] );
notDeepEqual( actual, expected, [message] );
strictEqual( actual, expected, [message] );
notStrictEqual( actual, expected, [message] );
throws( block, [expected], [message] );
```
Test Suite Convenience Methods Reference (See [test/data/testinit.js](https://github.com/jquery/jquery/blob/master/test/data/testinit.js))
------------------------------
### Returns an array of elements with the given IDs ###
```js
q( ... );
```
Example:
```js
q("main", "foo", "bar");
=> [ div#main, span#foo, input#bar ]
```
### Asserts that a selection matches the given IDs ###
```js
t( testName, selector, [ "array", "of", "ids" ] );
```
Example:
```js
t("Check for something", "//[a]", ["foo", "bar"]);
```
### Fires a native DOM event without going through jQuery ###
```js
fireNative( node, eventType )
```
Example:
```js
fireNative( jQuery("#elem")[0], "click" );
```
### Add random number to url to stop caching ###
```js
url( "some/url.php" );
```
Example:
```js
url("data/test.html");
=> "data/test.html?10538358428943"
url("data/test.php?foo=bar");
=> "data/test.php?foo=bar&10538358345554"
```
### Load tests in an iframe ###
Loads a given page constructing a url with fileName: `"./data/" + fileName + ".html"`
and fires the given callback on jQuery ready (using the jQuery loading from that page)
and passes the iFrame's jQuery to the callback.
```js
testIframe( fileName, testName, callback );
```
Callback arguments:
```js
callback( jQueryFromIFrame, iFrameWindow, iFrameDocument );
```
### Load tests in an iframe (window.iframeCallback) ###
Loads a given page constructing a url with fileName: `"./data/" + fileName + ".html"`
The given callback is fired when window.iframeCallback is called by the page.
The arguments passed to the callback are the same as the
arguments passed to window.iframeCallback, whatever that may be.
```js
testIframeWithCallback( testName, fileName, callback );
```
