WordPress Developer Function Reference
I’ve been sitting on this one for a while, because I’ve been waiting to finish a few features. This one feature is still not complete, but I did something today using Google’s new Coop system that merits a little attention.
You may have visited RedAlt before for various reasons. RedAlt houses a cross-reference of WordPress source code, not just for the trunk (current in-development code), but for both the 2.0 branch (which is the current in-release version), and 1.5.2. These are generated with PHPXref, a tool (written in Perl?) that parses the PHP source code and creates all the links to output and such. So that’s pretty cool. There are a few installations of the XRef’ed WordPress code in various places on the net, but I’m not sure that all of those sites provide XRefs for prior WordPress versions, which may be of use if you’re still using the stable versions of old.
