Grammar for (Glasgow) Haskell
Is this available as a happy file (or something similar)? I tried searching the 6.10.1 source package for *.y, but the three files I found don't seem to be what I'm looking for. What I want to try to do is to generate C wrappers to call GHC-compiled code by parsing foreign export declarations. But I figure just searching the code for a regular expression on the lines of foreign[ ]+export is going to be over-simplistic. But I'd rather not type in all the Haskell grammar myself (I'm lazy - you wouldn't expect any other sort of person on this list, I assume :-) ). -- Colin Adams Preston Lancashire

ls compiler/parser reveals... Lexer.x Parser.y.pp However you might get further using the ghc api package. Duncan
