Re: [Haskell-cafe] Calling Haskell from other languages?
Quoth Colin Paul Adams <colin@colina.demon.co.uk>: | Is there a way to call Haskell code from other languages? I have looked on | the wiki, and as far as I can see, it only talks about the other way | round (when Haskell is the main program). There sure is a way to call from other languages - cf. "foreign export" - but don't know how hard it would be to make Haskell live without its "main", which performs a lot of runtime initialization. For me (with nhc98) it's a lot easier to use a Haskell "main" that's just a brief wrapper: module Main (main) where import NHC.FFI foreign import ccall "cmain" cmain :: IO () main = cmain (... where "cmain" is an external entry point in the C code, which can then call Haskell as required.)
