Hi
I'd like to work on this too. But I I'm lacking some knowledge here.
At the moment cabal is using ReadP, right?
Am I also right that ReadP is lacking user friendly error messages compared to parsec?
I like the idea of using either { ; ; } or indentation. Thus you have best of both styles, C and python such like the haskell language.
So would it be ok to use parsec instead of ReadP?
Another advantage of Parsec is that then you'd be able to install a Hugs package without passing the -98 flag every time. ReadP requires forall, but Parsec doesn't unless you use the expression parser, which I doubt Cabal would require.
This will also make it easier to do a Yhc port of Cabal.
Actually I fixed that. The issue was that hugs's version of ReadP needed -98 and Cabal's 'compat' version didn't, so I just changed the ifdefs so that hugs always uses the compat implementation rather than it's own. Duncan
