hsc2hs translates metalanguage such as that to the code GHC expects.

[Haskell-cafe] FFI / enums

2011-11-07 Thread Johannes Waldmann 
Does this work with  "ghc -XForeignFunctionInterface" ?
http://en.wikibooks.org/wiki/Haskell/FFI#Enumerations

I am getting a syntax error right after "#{".
But then, the description is for "hsc2hs" (not  ghc).

And it mentions macros, while C meanwhile has "real" enums.
Well, at leat one can write  "enum match { foo, bar }".

The FFI Addendum does not mention enums at all.

So - what's the agreeable way to do this? - Thanks, J.W.
