YUI Compressor 2.4.6 发布，引入批处理多个文件功能

YUI Compressor 2.4.6 发布了。这个版本主要更新了Compressor对 CSS minification 的处理，并引入了单一命令批处理多个文件的功能。

YUI Compressor 是一个用来压缩 JS 和 CSS 文件的工具，采用Java开发。

该版本的亮点：

CSS minification

• Fixed numerous bugs that break the compressor and/or the resulting minified files.
• Added documentation on what exactly the minifier does and also which CSS hacks it tolerates.
• There’s a JavaScript port of CSS min in case it’s more suitable for your build process.Here’s also a test web UI that uses the JavaScript port, where you can experiment with the minifier.
• A significant number of new tests added (but you can add even more).
• Safe handling of some CSS features that are getting more adoption such as media queries and CSS3 transforms.

Batch processing

Compressor另一个显著改进就是支持单一命令批处理多个文件，这样能显著减少你处理文件的时间, 特别是当你有大量的文件需要压缩时。

示例：

the following commands minify all .js and .css files and write the minified files with a “-min.css” suffix.

$ java -jar yuicompressor.jar -o '.css$:-min.css' *.css
$ java -jar yuicompressor.jar -o '.js$:-min.js' *.js
