Flake not working #824

dwarfmaster · 2020-08-16T12:21:47Z

When trying to use haskell.nix as a flake, I get the error attribute 'currentSystem' missing in pkgs/top-level/impure.nix. This is to be expected, since currentSystem is unavailable in flakes. But, from my understanding, the reason it tries to access it is because localSystem has not been passed as argument.

flake.nix

{
 description = "Builds the Untitled Language™ compiler";

  inputs = {
    haskell.url = github:input-output-hk/haskell.nix;
  };

  outputs = { self, haskell }:
    let

      system  = "x86_64-linux";
      pkgs    = haskell.legacyPackages.${system};

      project = pkgs.haskell-nix.project {
        src = pkgs.haskell-nix.haskellLib.cleanGit {
          name = "Untitled-Language";
          src  = ./.;
        };
        compiler-nix-name = "ghc8101";
      };
      drv     = project.components.exes.Untitled-Language;

      shell   = project.shellFor {
        packages     = hpkgs: with hpkgs; [ Untitled-Language ];
        withHoogle   = true;

        # Tools
        tools        = {
          cabal = "3.2.0.0";
          hlint = "2.2.11";
        };

        # Other packages
        builtInputs = with project.haskellPackages; [
        ];

        # Prevent cabal from choosing dependencies not provided by nix
        exactDeps   = true;
      };

    in {
      packages.${system}       = {
        untitled-language = drv;
      };
      defaultPackage.${system} = self.packages.${system}.untitled-language;
      devShell.${system}       = shell;
      apps.${system}           = {
        compiler = {
          type    = "app";
          program = "${self.defaultPackage.${system}}/bin/Untitled-Language";
      };

I'm not sure what is important, so I included everything.
