question: How to use pinned `lib` in flake-parts modules?

[gabyx]

I am wondering how to override the default argument lib such that I can pin it to my nixpkgs library (e.g. input.nixpkgs.lib)

Can I do this with?

{
  inputs,
  ...
}:
{
      _module.args.lib = inputs.nixpkgs.lib;
}

and then every module will use lib with my thing?

I guess mkFlake passes the lib it locks from the input?

Yeah flake input follows is the way to do it, if you really need to.

I've turned the lib module argument into its own little section just now: https://flake.parts/module-arguments.html#lib

@roberth : So you dont recommend doing:

    inputs.flake-parts.lib.mkFlake
      {
        inherit inputs;
        specialArgs = {
          inherit (inputs.nixpkgs) lib;
        };
      }

I just wanted sure I use the latest lib, from nixpkgs everywhere, but do not affect the flake-parts logic?
But, what I am doing works, but I think is bogus cause if I would use lib.mkOption (hypothetical different) it would not match woth flake-parts would expect in its call to lib.evalModules so its wrong I guess. correct?

I believe that's mostly equivalent to flake-parts.inputs.nixpkgs-lib.follows = "nixpkgs";, but slightly messier because the original nixpkgs-lib is still used in a few places.
That's generally not a big deal because versions of lib are usually* compatible.
