Package won't compile

[meditans]

Hi, is this package still mantained? It fails when I try to compile the 0.5 version for hackage with a bunch of errors in the pretty.hs file.

I have the same issue, such a shame for this awesome tool!

Could you copy paste the errors here?

I have the same issue. It's reproducible. Apparently, Language.Haskell.Exts.Syntax changed in version 1.16.x of the haskell-src-exts package. It seems like the Syntax.hs file is a big copy-paste of their file with some hacks here and there.

This project needs a stack.yaml with working resolver. This would guarantee correct compilation at all times.
