"To install Snap, simply use cabal. It’s up to you whether or not you want to use the Heist templating library. It is not required if you just want to use the rest of Snap."

But I haven't seen what other options are in place for simple templating. Presumably you could use Hamlet or something, if you wire it in.

It should include at least some basic string interpolation stuff so you can so simple output in a simple way.

Sorry you feel that way, at least it's optional. The idea is that we are interesting in doing DOM-level transformations bound to html tags and there just isn't a robust HTML5 DOM parser available for Haskell.

http://www.alsonkemp.com/programming/a-haml-parser-for-haske... is young (but not) but looks (pretty) hype.

What don't you like about XML-based templating?
