I was able to get `ghc-mod` building for both 8.0 and 8.2: https://github.com/jwiegley/nix-config/blob/master/overrides.nix#L249 Oddly, I need to use the `ghc802` branch for 8.2, and `master` for 8.0.

Oh, hey, that makes total sense @hvr! :)

@gilligan I haven't been using ghc-mod, so I have no working Nix expression for you yet.

Note that this same problem is an issue for recent Nix.

Just tried today. The disappearance of `proof-shell` is the first one that bit me.

@bmag This didn't work for me, btw. After your recommended setting, purpose still invokes ido rather than ivy.

@joeyh No, I'm not longer working on this project. You can remove me as a maintainer.

I would love to use hsenv, but I've never been able to get it to work for any of the meaningful projects I work on on my Mac, while cabal-dev...

I've switched to using hsenv, but am having the exact same problem. It can't find any of my installed packages, while GHC can in the same environment.

Agreed, cabal sandbox has been working great, just need to convert over our tooling to use it.
