Hello,
I added a brief section to the happstack crash course on using MACID:
http://www.happstack.com/docs/crashcourse/HappstackState.html
That should hopefully get you started.
The example uses happstack state with happstack server. But there is
really no connection between the two.
Hope this helps! If you have additional questions, feel free to ask!

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 = Ev (StateT state STM)
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!
