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.
