Being frustrated with GHC version mismatches when I wanted to use HIE through hie-nix, I created this little project to provide Nix builds for all GHC versions. This is very useful when you have a lot of Haskell projects and don’t want to keep them all in sync with your HIE version. Linux caches are available through cachix.
You are the hero we need but don’t deserve!
Let me know if I can help with this. Haskell derivations can become such a mess sometimes.
