This should help nix users start working on ziglings without the complexity of making sure they are on a supported version of zig and zls.

This should help nix users start working on `ziglings` without the complexity of making sure they are on a supported version of `zig` and `zls`.

Thank you for linking the other PRs for reference!

I do agree with your statement:

Thank you for the suggestion! However, we typically avoid including configuration details in our exercises to keep them focused and straightforward.

Yes, although it is trivial to just run nix shell 'github:mitchellh/zig-overlay#master', this PR also ensures that zls is available in the dev shell and also makes sure that it's zig input matches the zig version used/defined via mitchellh/zig-overlay either via an overlay or overrideAttrs.

e.g.

overrideAttrs

zls = inputs.zls-overlay.packages.${system}.zls.overrideAttrs (finalAttrs: previousAttrs: {
 nativeBuildInputs = [zig];
});

#...
zls = pkgs.stdenvNoCC.mkDerivation {
 name = "zls";
 version = "master";
 meta.mainProgram = "zls";
 src = fs.toSource {
 root = ./.;
 fileset = fs.intersection (fs.fromSource (pkgs.lib.sources.cleanSource ./.)) (
 fs.unions [
 ./src
 ./tests
 ./build.zig
 ./build.zig.zon
 ./deps.nix
 ]
 );
 };
 nativeBuildInputs = [zig];
