Alternative Haskell package set

hspkgs - an alternative haskell package set

The goal is to provide a reusable, bleeding edge, set of packages based on nixpkgs that works with the most recent ghc version. Some packages may includes un-merged PR to make it work. Feel free to add your own workarounds.

Features

Packages:

• ghc-9.2.5
• weeder-2.4.1
• calligraphy-0.1.3
• apply-refact-0.10.0.0
• kubernetes-client-0.3.2.0

Helpers:

• mk-nixgl-command : run a program with nixGL
• mk-static-haskell : build a static binary with musl
• run-hoogle : a devshell with a run command to start the service

Usage

Use the output overlays.hspkgs, for example in your flake:

{
  inputs = {
    nixpkgs.url =
      "github:NixOS/nixpkgs/d46be5b0e8baad998f8277e04370f0fd30dde11b";
    hspkgs.url = "github:podenv/hspkgs";
  };

  outputs = { self, nixpkgs, hspkgs }:
    let
      pkgs = import nixpkgs {
        system = "x86_64-linux";
        overlays = [ hspkgs.overlays.hspkgs ];
      };
      pkg = pkgs.hspkgs.callCabal2nix "my-project" self { };
      exe = pkgs.haskell.lib.justStaticExecutables pkg;
    in {
      packages."x86_64-linux".default = exe;
      devShell."x86_64-linux" = pkgs.hspkgs.shellFor {
        packages = p: [ pkg ];
        buildInputs = [
          pkgs.cabal-install
          pkgs.haskell-language-server
          pkgs.weeder
        ];
      };
    };
}

Follow the same upstream nixpkgs, see demo in run-monomer:

{
  inputs = {
    hspkgs.url = "github:podenv/hspkgs/PIN_COMMIT";
  };

  outputs = { self, hspkgs }:
    let
      pkgs = hspkgs.pkgs;
      pkg = pkgs.hspkgs.callCabal2nix "my-project" self {};
    in {};
}
