- Bumped nixpkgs, so that's a true GHC 9.4.2 and not 9.4.0, which was failing in cabal which because it was detecting <=9.4.1. - Fixed GHC 9.4 overrides for dependencies - Use the "default" GHC environment for tooling in the shell. Hence it rebuilds less. - I introduced a flake for cabal-hashes, hence it can be updated automatically (with `nix flake update`) and hence we can use `callHackage` for any hackage package.

Hello. Could you review? It fixs the nix build with all the ghc versions. Does not work on macos for some reasons that I don't understand. I'd like to see that merged before attempting further cleaning / fixing of the nix solution. |
