Hello,
I'm wondering how can I use Happstack's MACID in my application without
breaking everything.
I have a monad like that:
type Comm = StateT Communication IO
type GameState a = StateT Game Comm a
and many functions like:
foo :: GameState ()
foo = do
lift $ putComm
modify <someAction>
The state of the game is stored in Game.
Comm is used as an abstraction to communicate over several channels with
players.
Whereas MACID asks to use:
type *Update* state =
Evhttp://happstack.com/docs/0.5.0/happstack-state/Happstack-State.html#t%3AEv(
StateThttp://happstack.com/docs/0.5.0/mtl/Control-Monad-State-Lazy.html#t%3AStateTstate
STM http://happstack.com/docs/0.5.0/base/GHC-Conc.html#t%3ASTM)
How can I use this without modifying everything??
I understand that MACID must record the <someAction> from above but the
message should not.
Thanks for help!
