I was impressed after your tip about
'Language.Haskell'. In a few minutes, I got my
dream Haskell formatter. Here it is, parsed by
itself. Thanks for your tip.
module Main (Main.main) where
{ import System.IO;
import Language.Haskell.Parser;
import Language.Haskell.Pretty;
import Text.PrettyPrint.HughesPJ;
main :: IO ();
main
= do
{ program <- getContents;
ParseOk parse <- return $
parseModule program;
estilo <- return $ Style PageMode 50 1.0;
modo <- return $
PPHsMode 0 0 0 0 0 3 True
PPSemiColon
False
True;
putStrLn $
prettyPrintStyleMode estilo modo
parse}}
