Where is a good guide for Drupal themeing?

Question

I'm new to Drupal, and frankly after reading through the Drupal documentation, their guide to themeing isn't all that helpful. Maybe I'm just misunderstanding, but it seems like there are certain variables you always have access to and different functions you can define to override or implement behavior.

Long story short, I'd like to be able to trace through the Drual themeing code to understand hwo it works. Doesn't seem like it should be all that difficult, but I'm having a hard time finding a good reference. Anyone know of one?

Answer 2

There are a few different resources you can use that might help out:

• You can use the irc channel on freenode: #drupal-themes
• A module that I hear a lot of themers like is the Devel module - http://drupal.org/project/devel. This is what will allow you to trace through the code and see what variables, function calls, etc. are being used.
