Replace build system with a faster new one that uses Node and UglifyJS and generates smaller minified files. Also removes builds through rake/ant since having 3 different build systems was too much to maintain (make was the only one consistently kept up-to-date). Fixes #7973.

[jQuery](http://jquery.com/) - New Wave Javascript
|
||||
================================
|
||||
==================================================
|
||||
|
||||
What you need to build your own jQuery
|
||||
---------------------------------------
|
||||
* Make sure that you have Java installed (if you want to build a minified version of jQuery).
|
||||
If not, [go to this page](http://java.sun.com/javase/downloads/index.jsp) and download "Java Runtime Environment (JRE) 5.0"
|
||||
--------------------------------------
|
||||
|
||||
Build Options
|
||||
--------------
|
||||
In order to build jQuery, you need to have GNU make 3.8 or later, Node.js 0.2 or later, and git 1.7 or later.
|
||||
(Earlier versions might work OK, but are not tested.)
|
||||
|
||||
You now have **three** options for building jQuery:
|
||||
Windows users have two options:
|
||||
|
||||
* **`make`**: If you have access to common UNIX commands (like `make`, `mkdir`, `rm`, `cat`, and `echo`) then simply type `make` to build all the components.
|
||||
1. Install [msysgit](https://code.google.com/p/msysgit/) (Full installer for official Git),
|
||||
[GNU make for Windows](http://gnuwin32.sourceforge.net/packages/make.htm), and a
|
||||
[binary version of Node.js](http://node-js.prcn.co.cc/). Make sure all three packages are installed to the same
|
||||
location (by default, this is C:\Program Files\Git).
|
||||
2. Install [Cygwin](http://cygwin.com/) (remember to install the git and make packages) and follow the
|
||||
[Node.js build instructions](https://github.com/ry/node/wiki/Building-node.js-on-Cygwin-%28Windows%29) or install
|
||||
the [binary version of Node.js](http://node-js.prcn.co.cc/).
|
||||
|
||||
* **`rake`**: If you have Ruby Rake installed (on either Windows or UNIX/Linux), you can simply type `rake` to build all the components.
|
||||
Mac OS users should install Xcode (comes on your Mac OS install DVD, or downloadable from
|
||||
[Apple's Xcode site](http://developer.apple.com/technologies/xcode.html)) and
|
||||
[http://mxcl.github.com/homebrew/](Homebrew). 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 make, git, and node, or build from source
|
||||
if you swing that way. Easy-peasy.
|
||||
|
||||
* **`ant`**: If you have Ant installed (or are on Windows and don't have access to make). You can download Ant from here: [http://ant.apache.org/bindownload.cgi].
|
||||
|
||||
How to build your own jQuery
|
||||
-----------------------------
|
||||
----------------------------
|
||||
|
||||
*Note: If you are using either `rake` or `ant`, substitute your chosen method in place of `make` in the examples below. They work identically for all intents and purposes. Quick reference is also available for `rake` by typing `rake -T` in the `jquery` directory.*
|
||||
First, clone a copy of the main jQuery git repo by running `git clone git://github.com/jquery/jquery.git`.
|
||||
|
||||
In the main directory of the distribution (the one that this file is in), type
|
||||
the following to make all versions of jQuery:
|
||||
Then, to get a complete, minified, jslinted version of jQuery, simply `cd` to the `jquery` directory and type
|
||||
`make`. If you don't have Node installed and/or want to make a basic, uncompressed, unlinted version of jQuery, use
|
||||
`make jquery` instead of `make`.
|
||||
|
||||
make
|
||||
The built version of jQuery will be put in the `dist/` subdirectory.
|
||||
|
||||
*Here are the individual items that are buildable from the Makefile:*
|
||||
To remove all built files, run `make clean`.
|
||||
|
||||
make init
|
||||
|
||||
Pull in all the external dependencies (QUnit, Sizzle) for the project.
|
||||
|
||||
make jquery
|
||||
|
||||
The standard, uncompressed, jQuery code.
|
||||
Makes: `./dist/jquery.js`
|
||||
|
||||
make min
|
||||
|
||||
A compressed version of jQuery (made the Closure Compiler).
|
||||
Makes: `./dist/jquery.min.js`
|
||||
|
||||
make lint
|
||||
|
||||
Tests a build of jQuery against JSLint, looking for potential errors or bits of confusing code.
|
||||
|
||||
make selector
|
||||
|
||||
Builds the selector library for jQuery from Sizzle.
|
||||
Makes: `./src/selector.js`
|
||||
|
||||
Finally, you can remove all the built files using the command:
|
||||
|
||||
make clean
|
||||
|
||||
Building to a different directory
|
||||
----------------------------------
|
||||
---------------------------------
|
||||
|
||||
If you want to build jQuery to a directory that is different from the default location, you can...
|
||||
If you want to build jQuery to a directory that is different from the default location, you can specify the PREFIX
|
||||
directory: `make PREFIX=/home/jquery/test/ [command]`
|
||||
|
||||
**Make only:** Specify the PREFIX directory, for example:
|
||||
|
||||
make PREFIX=/home/john/test/ [command]
|
||||
|
||||
With this example, the output files would be contained in `/home/john/test/dist/`
|
||||
With this example, the output files would end up in `/home/jquery/test/dist/`.
|
||||
|
||||
**Rake only:** Define the DIST_DIR directory, for example:
|
||||
|
||||
rake DIST_DIR=/home/john/test/ [command]
|
||||
|
||||
With this example, the output files would be contained in `/home/john/test/`
|
||||
Troubleshooting
|
||||
---------------
|
||||
|
||||
*In both examples, `[command]` is optional.*
|
||||
Sometimes, the various git repositories get into an inconsistent state where builds don't complete properly
|
||||
(usually this results in the jquery.js or jquery.min.js being 0 bytes). If this happens, run `make clean`, then
|
||||
run `make` again.
|
||||
|
||||
**Ant only:** You cannot currently build to another directory when using Ant.
|
||||
