Can't use my nixpkgs

[deemp]

It seems like it doesn't work with modern nixpkgs. At least when I use follows, I get

nix-repl> inputs.gitignore.lib.gitignoreSource
error: attribute 'lib' missing

       at /nix/store/qjw6nq34h4s78573nh70gsl2a2qz76mz-source/flake.nix:5:33:

            4|   outputs = { self, nixpkgs }: {
            5|     lib = import ./default.nix {
             |                                 ^
            6|       inherit (nixpkgs) lib;

       … while evaluating the attribute 'gitignore.lib.gitignoreSource'

       at /nix/store/qjw6nq34h4s78573nh70gsl2a2qz76mz-source/default.nix:36:10:

           36|   inherit
             |          ^
           37|     gitignoreSource

Could you please fix it, @roberth?

I can't reproduce this with

$ cd path/to/gitignore.nix/
$ # update to latest master
$ nix flake lock --recreate-lock-file
warning: updating lock file '/home/user/h/gitignore.nix/flake.lock':

Maybe the lock file was corrupted; perhaps by a merge conflict or rebase? Did you try nix flake lock --recreate-lock-file? If that doesn't solve the problem, I'll need a minimal but complete reproducing example.

Also, are you sure you need this? It seems that you're using flakes, so unless you're using path-based flakes with repos inside, you shouldn't need gitignore.nix.

Thanks! I figured out I wrongly used follows
