Another quick update: PackR received an update today that means that when
you use its
:shrink_vars mode, it won’t minify any variables called
$super is used to implement inheritance and your class
definitions will break if you change its name.
I didn’t really want to make PackR inconsistent with Dean’s original, but without this feature Prototype code is essentially unpackable beyond basic whitespace-stripping, and given that Ruby/Rails users are likely to be using Prototype, I figured it was worth the addition. It also lets you specify your own protected variable names – I’ll be updating the docs soon.
To update, just
gem install packr or
ruby script/plugin install http://svn.jcoglan.com/packr/trunk/packr
