Javascript file Concatenation and Compression

Currently there are several way to do this, you can see this one:

YUI Compressor
[http://www.julienlecomte.net/blog/2008/10/80/]

The YUI Compressor uses a slightly modified version of the parser used in the Rhino JavaScript engine.However, it is Java based tool and you need compile/run etc. Actually it is the best mini tool I found so far.

If you use Apatan/Eclipse, maybe you need think this one.

JSConcatenation
[http://www.rockstarapps.com/pmwiki/pmwiki.php?n=JsLex.JSConcatenation]

Using this tool, will make your easy to mini your file into any output as your like. Rockstarapps.com has an aptana 'feature' that you download via aptanas internal software update engine. It allows for many other things but I was only interested in the JS tools it offers.

It is very straight forward, select files in the resources pane or better yet select your script tags right in an HTML document and "right click--> rockstarapps -->concatenate javascript". It produces an xyz.all.js file (with comments), a xyz.all.min.js file (without comments, linebreaks and spaces) an xyz.all.ycomp.js file (minified and yui compressed), AND it even includes a xyz.all.ycomp.js.gz (Gzipped).
