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. ________________________________________ From: Malcolm Wallace [malcolm.wallace@me.com] Sent: Monday, January 03, 2011 12:44 AM To: Jane Ren; GHC-users List Cc: haskell-cafe@haskell.org Subject: Re: GHC ParseTree Module You will be more likely to get an answer on the ghc-users mailing list (cc'ed).

Hi,
Does anyone know what GHC module gets the AST and type info of some source code? This is the GHC module that converts all of Haskell into an AST with a small number of pattern cases, where each AST node is annotated with the Haskell type.
