Inconsistent rendering of type signatures #251

Closed Lysxia closed 6 years ago

Lysxia commented 6 years ago

Here are three results for withExceptT which seem to have the same source but all of them have type signatures with distinct parenthesizations, one incorrect.

Haddock provides the type signatures, and previous versions of Haddock were a bit buggy. Looking at the incorrect line, it's also present in https://hackage.haskell.org/package/mtl-2.2.2/docs/mtl.txt - so doesn't seem like a bug Hoogle can do much about. I suggest the only thing I can do is make sure transformers comes before mtl in the ranking, at least then the first answer will be correct.

I added a nasty hack that puts transformers above mtl so from tomorrow evening it will have at least a correct answer first. I don't think there's much to do until mtl re-uploads correct docs.

Thanks! That seems like the best solution for now.
