This project is a Qt binding generator for Haskell based on the Smoke project from KDE. Smoke is a special Qt-oriented parser along with some extra metadata to provide some introspection information via some shared libraries accessible from C.

Dynamic languages can use Smoke to generate bindings at run-time on-demand. More static languages can use tools like humidor to generate the bindings statically ahead of time. The Smoke library also provides a convenient mechanism to call any Qt method through a plain C calling convention, rather than relying on a C++ calling convention.

The project isn't quite in a working state right now, but it generates a Haskell module for each Qt class, along with some typeclasses to establish the relevant subtyping relationships. The code to generate a typeclass for each method is nearly working. A few major TODO items:

• Map Haskell types to C, especially Text and some container types

• Finish generating method dispatchers

• Permit subclassing (possibly via TH) from Haskell; this is critical. Lessons learned from hsqml could be useful here for registering subclasses with the Qt metaobject system. Smoke also seems to provide a little support in this area.
