YUI Compressor

This fork adds Ant tasks to compress css and JavaScript files. Using these tasks is easier and faster than using the <java> task equivalent and spawning a new process for each file to process.

Usage:

You first need to define the new task inside a target element or directly in the project element of your Ant build script with:

<taskdef
        resource="com/yahoo/platform/yui/compressor/ant/antlib.xml"
        classpath="/path/to/yuicompressor.jar"/>

Or:

<taskdef
        name="jscompressor"
    classname="com.yahoo.platform.yui.compressor.JavaScriptCompressorTask"
    classpath="/path/to/yuicompressor.jar"/>
<taskdef
        name="csscompressor"
    classname="com.yahoo.platform.yui.compressor.CssCompressorTask"
    classpath="/path/to/yuicompressor.jar"/>

The tasks are then available with all the command line options and the same default (the following shows their default values):

<jscompressor srcfile="script.js" dstfile="script.min.js"
        linebreak="-1" charset="UTF-8"
        nomunge="no" preservesemicolons="no" disableoptimizations="no"/>

<csscompressor srcfile="style.css" dstfile="style.min.js"
        linebreak="-1" charset="UTF-8"/>

You can use these tasks to compress file in place:

<!-- build/js/script.js content is now compress.
         Make sure to keep a copy of the source! -->
<jscompressor srcfile="build/js/script.js"/>

<!-- all files in build/ and its subfolders are compress.
         Make sure to keep a copy of the source! -->
<jscompressor>
    <fileset dir="build/">
                <include name="**/*.js"/>
        </fileset>
</jscompressor>

To creating a compressed copies with a different extension:

<!-- Create a compress copy of build/js/script.js
         in build/js/script.min.js. -->
<jscompressor srcfile="build/js/script.js" extension="min.js"/>

<!-- The same but for all the js files in build/
         and its subfolder. -->
<jscompressor extension="min.js">
    <fileset dir="build/">
                <include name="**/*.js"/>
        </fileset>
</jscompressor>

Or to creating compressed copies in a different directory:

<!-- Create a compress copy of src/js/script.js
         in build/js/script.js. -->
<jscompressor srcfile="src/js/script.js" dstdir="build/js/"/>

<!-- Create a compress copy from all the js files in src/
        and its subfolder, to the build/ folder. -->
<jscompressor dstdir="build/">
    <fileset dir="src/">
                <include name="**/*.js"/>
        </fileset>
</jscompressor>

To do:

• Add support for file list and concatenation.
