[solved] error when using opts (stable vs unstable branch)

[oliver-cfc]

Firstly, I'm new to nix/flakes/home-manager so assume I don't know what I'm talking about.

My setup is flakes/home-manager. I have nixvim in the inputs and outputs in flake.nix and I import inputs.nixvim.homeManagerModules.nixvim in my home.nix. Then I import nixvim.nix (a file I created)

All this is working until I put opts in nixvim.nix
The full nixvim.nix is:

{
  programs.nixvim = {
    enable = true;

    defaultEditor = true;
    viAlias = true;
    vimAlias = true;

    colorschemes.catppuccin.enable = true;

    plugins = {
      lualine.enable = true;
      bufferline.enable = true;
      treesitter.enable = true;
      which-key = {
        enable = true;
      };
    };

    opts = {};

  };
}

but this gives me an error when I try to 'home-manager switch --flake....'

error: The option `programs.nixvim.opts' does not exist. Definition values:
       - In `/nix/store/vkaad2fza7r8y418kjk9bcl97b2llg17-source/home-manager/pkgs/nixvim/nixvim.nix': { }

If I hash out the opts line, all it builds/switches as expected.

What am I missing?

The opts option used to be called options. If you are using a NixOS stable branch of nixvim or your flake.lock hasn't been updated in a while then opts won't exist.

[oliver-cfc]

that was it exactly - stable branch. Switched opts for options and everything built as expected.
Thanks!
