Using Language.Haskell, such a program is almost trivial:
--
-- strip comments from haskell source
--
{- the main module -}
import Language.Haskell.Parser
import Language.Haskell.Pretty
main = interact $ \s -> case parseModule s of
ParseFailed loc str -> (show loc) ++ "\n"
ParseOk m -> (prettyPrint m) ++ "\n"
And running this program on itself:
$ runhaskell A.hs < A.hs
module Main (main) where
import Language.Haskell.Parser
import Language.Haskell.Pretty
main
= interact $
\ s ->
case parseModule s of
ParseFailed loc str -> (show loc) ++ "\n"
ParseOk m -> (prettyPrint m) ++ "\n"
Hehe, it also pretty prints :-)
