The Advanced Theme Construction Kit, which integrates a derivative of the Yahoo grids CSS library within a Drupal framework, was updated and released for Drupal 6 today.
After religiously following the changes to Drupal 6's theme-layer for many months now, as well as actively coding a Drupal 6 module for the past month and a half, I was thinking that upgrading ATCK was going to be a snap...
In some ways it was, but the Drupal 5 to Drupal 6 theme conversion was by far the most complicated theme update I've seen since being involved with Drupal (4.5 onward). As it turns out the Drupal 5 template.php file for ATCK was almost completely useless, and it was with great thanks that I (again) borrowed heavily from Hunchbaque's template.php in order to get the desired granularity for classes/id's.
One area I did depart from core and the Hunchbaque theme on is the handling of css files. Allowing for the possibility that there is something that I'm 'missing', I can't say that I'm currently very happy with Drupal's new method of adding stylesheets via .info files, nor with the functions that Hunchbaque currently uses in it's template.php to add IE-only css. The core method of stylesheet handling makes stylesheets a bit of a pain to refresh, and I found both methods to be unreliable with respect to conditionally adding stylesheets.
In the end 'old fashioned' conditional statements were implemented within page.tpl.php, and a custom function added to template.php. Along with being reliable, this combo provides the ability to tell Drupal to NOT import specific core css files (e.g., if you don't want the node.css file loaded - simply add a line to the function inside ATCK's template.php and node.css never gets loaded).
The most satisfying part of the upgrade was that the centerpiece of ATCK, the Yahoo Grids-inspired CSS library, did not require a single change. So this part has proven to indeed be modular and Drupal version independent. :-)
Future development plans for ATCK
* Possibly add the edit functionality that the Zen theme has introduced to make managing blocks and views easier.
