exporting events generated by makeAcidic

[Bob Hutchison]

Hi,

Is there a way to export the events/data constructors generated by makeAcidic? I've tried several variations with all but two ending up with anything from an out of scope data constructor to orphaned instance errors.

As it stands now I'm having to take one of two approaches:
- export everything in the module (e.g. "module MyModule where").
- define synonyms for the data constructors generated by makeAcid and export those.

The synonym approach is the best that I've come up with but is ugly and annoying since you have to keep the signature up-to-date if you're going to define a top-level signature for the synonym.

My knowledge of the available options in Haskell seems pretty shaky just now, any help will be appreciated. I know it has to do with template Haskell and when it's run (i.e. after the module declaration.) I've been running in circles and at this point, I expect the solution to be embarrassingly obvious.

Thanks,
Bob

I'm not sure I understand the problem/question. Can't you just do:

module MyAcid (MyState(..), MyEvent(..)) where

data MyState = ...

myEvent :: Query MyState Int
myEvent = ...

$(makeAcidic ''MyState ['myEvent])

Thanks! BTW, that's kinda what I meant by "embarrassingly obvious" :-(
