s.clover:
hvac sounds interesting but at that time at least it was not clear whether it was stable or would continue to be maintained.
xhtml and HStringTemplate were overkill for what I wanted, so I wound up just using the FastCGI and CGI toolkits themselves. They are surprisingly nice, and with a little bit of wrappers around them for things like validating forms, have worked exceptionally well.
I'm in a position now where I can make a reasonable promise that hvac will not only be maintained but undergoing continued development. I just, for example, hooked in some basic postgresql support yesterday (although the changes are not tested/pushed to the repo yet). (Speaking of which, I noticed that the HDBC postgresql bindings don't set seState on an error -- is this intentional, or something that should be fixed up?)
Sterling, Would you like to add some text on hvac and your other web libs to our web programming wiki/faq, http://haskell.org/haskellwiki/Practical_web_programming_in_Haskell Ideally, in a few months time, with enough additions, the full story will be covered on this wiki page, and it will be a great boon to developers wanting to work in Haskell, in this hot area. -- Don
