Nix / NixOS

I don't really like flake-parts or flakelight. I think that part of this is sheer brutalism (I don't mind writing bare Nix) but part of it is a desire to not rely on flakes which don't carry their own weight, following Wirth's principle for compilers.

How can you say this and still use flake-utils? All it does is manage your systems. You can write your own one-liner for that

eachSystem = f: lib.genAttrs systems (system: f nixpkgs.legacyPackages.${system});

Where systems is automatically supplied as a flake input (I think), or you can supply your own list of systems to support. You can then use it like this:

devShells = eachSystem (pkgs: {
    default = # your devshell
}

You can of course modify eachSystem to have more function parameters other than pkgs.

See this blog which initially inspired me not to use flake-utils
