Hi,
I think I figured out what code I need to write to get the AST of a haskell
module (pasted below). Basically, I need to get the typed parsetrees of all
Haskell base libraries to do some analysis. But the that "parse" function
seems to produce a "parse error" for each one of the base libraries. In fact,
it only works ok if I use a simple test file which contains "n = 3". Any ideas?
parse :: String -> HsModule
parse syntax =
case parseModule syntax of
(ParseOk ast) -> ast
(ParseFailed loc msg) -> error $ (show loc)
main = do
file_content <- readFile targetFile
let ast = parse file_content
print ast
Thanks.

You will be more likely to get an answer on the ghc-users mailing list
(cc'ed). The ghc developers rarely follow -cafe.
