I've implemented a twisted.web2 resource for accessing Trac via WSGI. You can see both a working example and the code at http://foss.eepatents.com/DynamicSite/browser/branches/kiss-web2/dynamicsite... There's a StanResource class there that I'm using and think is kind of cool, too. I use the following python code to provide my root resource for the foss.eepatents.com site. (A copy is at http://deadbeefbabe.org/paste/34 in case the email version is too mangled to be useful.) Obviously, you'll want to personalize it for your own use and not call the home page "Ed Suominen's Free & Open Source Software Projects." This will all be part of an upcoming release of DynamicSite, a flexible, reasonably user-friendly vhost implementation of twisted.web2. Hopefully I will remain inspired to package it all up now that I've scratched my particular itch. Since I believe in generous usage of docstrings (hint, hint to the Twisted devs), the code in the kiss-web2 branch should be fairly easy to use even in its current raw form. Those interested in what can be (over)done with Nevow, dynamic image generation, intelligent caching, etc. might want to browse through the current revision (SVN:47) of trunk before I replace it with the "keep it simple stupid" twisted.web2 branch. Best regards, Ed Suominen
