(Probably) due to https://github.com/nix-community/nixvim/commit/efb004a61fb0173a2e5625c401ef6738ff2bea55 (from @khaneliman specifically https://github.com/nix-community/nixvim/blob/ee6ee48bbe1ffa88fd4b2af7d68ab0315bc817f0/plugins/git/gitgutter.nix#L196) the following error is observed:

       … while evaluating the option `home-manager.users.gador.programs.nixvim.extraPackages':

       … while calling anonymous lambda

Minimal, Reproducible Example (MRE)

programs.nixvim = {
    enable = true;
    plugins.gitgutter = {
      enable = true;
    };
};

[MattSturgeon]

Yeah, looks like it should be

extraPackages = [
  cfg.gitPackage
  cfg.grepPackage
]; 

[khaneliman]

Yeah, looks like it should be

extraPackages = [
  cfg.gitPackage
  cfg.grepPackage
]; 

grepPackage is a local variable, not a config option.
