A Rails rake file for compressing your Javascript with YUI
Here is a quick rake file I threw together to use with my Ruby YUI 2.0 (I-refuse-to-make-a-gem-
edition).
This of course should be used with the Ruby YUI Compressor I posted about the other day.
This script will tar/gzip all of your javascripts just incase something stupid happens. So you have a little safety net.

Wanna use it?
1. Drop it in your lib/tasks folder or wherever your Rakefile looks
You can compress 'everything' or specific files.
If you want to only compress specific Javascript files do:
1 2 3 | rake js:generate
# Edit your config/yui.yml file
rake js:yui |
If you want to compress "everything" (It actually won't compress files that contain ".min.". You can remove the regexp's if you don't like it.)
1 | rake js:yui COMPRESS=ALL |
Yay, now your raking it in (Pun harhar) w/ your web2.0 yui compressed rails app. Woot woot.
