haskades

Utility to generate bindings for BlackBerry Cascades.

Autogeneration of bindings for creating BlackBerry Cascades apps with Haskell back ends.

Run as:

./haskades HaskadesBinding.hs haskades_run.cpp haskades_run.h < Types.hs

Where Types.hs is a Haskell file containing a a sum type declaration named SignalToUI and another named SignalFromUI which fully specify the communication possible between the UI layer (which you write in QML) and the Haskell backend. QML code can access these signals on the app context object. Haskell code can emit signals by using the emit function exported from the generated HaskadesBinding. The emit call is threadsafe.

Text, Lazy Text, and String all end up as QString so that QML can work with them properly, and vice-versa. UTCTime becomes QDateTime. Int, Double, and () are passed through fairly directly. Other types may have support added as there is need.
