I've been having fun poking around Textmate. I spent today picking through the internals to create my own syntax coloring for PHP and Smarty. Smarty ( http://smarty.php.net/ ) is a templating system for PHP.

Anyone is welcome to download and modify at as they please. Of note : a complete php function list is included in the php syntax file. I'm quite please with the Smarty coloring, all html elements are in cool and muted tones, and all smarty template logic is in saturated and warm tones -- it's rather easy to see what's what.
