I'm using haskell-src to build a haskell compiler. I've compiled hscolour and haskell-src to java classes and used the result to colorize and report parsing errors in an eclipse editor. I use 1.0.1.3 and it reports unterminated comments on the token before the {- token so it is mildy informative and possibly an error in the implementation. haskell-src serves me well but i would like some better error reporting as "parse error" is quite non informative. I would like to avoid building my own parser and so would like to know what the options are for parsing haskell sources with an improved error reporting. I've no idea how i should share screenshots so i've uploaded to the first site i've found: http://imageshack.us/photo/my-images/853/scr1g.png/ http://imageshack.us/photo/my-images/706/scr2a.png/
