hstyle

Checks Haskell source code for style compliance.

Originally intended to automate style checking for the Snap project. But the project should be general enough to work with other style guides.

hstyle is a code style checker for Haskell programs. So far it's just a quick-and-dirty implementation of a few of the simplest requirements found in the Snap Framework's Haskell Style Guide. In the future we hope to build more sophisticated checking. The ultimate goal would be an automatic reformatter that generates gorgeous code--but that's a hard problem.
