This project provides a custom Ant task for compressing JavaScript and CSS files using YUI Compressor.
More information here: http://www.simonbuckle.com/2011/02/20/yui-compressor-ant-task/
The name of the Ant task is "yuicompressor" (see the example below). It supports the following attributes:
| Attribute | Required | Default Value |
|---|---|---|
| linebreak | No | -1 |
| munge | No | true |
| preserveAllSemiColons | No | false |
| disableOptimizations | No | false |
| verbose | No | false |
| todir | Yes | N/A |
| encoding | No | UTF-8 |
A full description of the attributes (apart from todir) can be found on the YUI Compressor site: http://developer.yahoo.com/yui/compressor/
It also expects two child elements: fileset and mapper. These are required elements. The first specifies the list of files to compress; the second prescribes how they should be saved once minimised.
To build it run: ant package.
Here's an example build file that looks for all the JavaScript files in the test directory and minimises them:
<taskdef resource="yuicompressor.tasks" classpath="dist/yuicompressor-taskdef-1.0.jar"/>
<target name="example">
<yuicompressor linebreak="40" todir="/var/www">
<fileset dir="${basedir}/test" includes="*.js"/>
<mapper type="glob" from="*.js" to="*-min.js"/>
</yuicompressor>
</target>
Save the file as build.example.xml in the root directory of the project. To run it, type the following: ant -lib lib/yuicompressor-2.4.2.jar -f build.example.xml.
(The task relies on YUI Compressor so this must be specified using the -lib option.)
Here's another example that compresses both CSS and JavaScript files:
<taskdef resource="yuicompressor.tasks" classpath="dist/yuicompressor-taskdef-1.0.jar"/>
<target name="example">
<yuicompressor linebreak="40" todir="/var/www">
<fileset dir="${basedir}/test" includes="*.css,*.js"/>
<mapper>
<globmapper from="*.css" to="*-min.css"/>
<globmapper from="*.js" to="*-min.js"/>
</mapper>
</yuicompressor>
</target>
