jsmin bails on extremely large libraries. about minify HOT 4 CLOSED

not quite sure why it is invalid. it's a perfectly valid point. a better 
alternative to jsmin and the pre mentioned 
script is http://joliclic.free.fr/php/javascript-packer/en/

JSMin doesn't "bail" on large libraries. The problem you're seeing is that 
Prototype,
Scriptaculous, and some other libraries are written with bad coding practices 
that
JSMin doesn't tolerate. The rule of thumb is that if JSLint throws warnings, 
you're
likely to run into problems with JSMin.

Packer is a reasonable alternative to JSMin, but whether or not it's better is
arguable. They both have their advantages and disadvantages.

I'd advise against using your regexp-based minification function. JavaScript is 
a
notoriously difficult language to parse correctly, and those regexps are 
absolutely
guaranteed to introduce errors (especially the 'remove extra spaces' regexp, 
which
doesn't take strings into account).

I believe I read someone now maintains JSMin-friendly versions of these 
libraries 
(or you can get pre-minified versions). Regardless, in version 2.x you can use 
the 
PHP5 Packer (or any other code) for certain files if you want. The 
configuration is 
a little tricky, but ask on the google groups.
