Config

Your nixvim config

{pkgs, lib, nixvim, ...}: {home-manager.users.usr1 = {
   imports = [
      nixvim.homeManagerModules.nixvim
   ];
};

[pta2002]

I think this might be related to #66... Have you tried just setting plugins.nixvim.enable = true?

[gilice]

was not related to nixvim but some weird behaviour of home-manager itself

[gador]

@gilice did you figure out what exactly caused the error?

[gilice]

@gador take this with two packets of salt because I didn't care enough to reproduce it.

What seemed to be happening was that if I add a home-manager module at a top-level, eg,

home-manager.users.user1 = {
  imports = [nixvim.homeManagerModules.nixvim];
};

it seems to work. However, if I put it somewhere in a file that is imported, adding one level of nesting:

configuration.nix

home-manager.users.user1 = {
  imports = [
    ./editr-config.nix
  ];
};

and then in

editr-config.nix

{pkgs, lib}: {
   imports = [nixvim.homeManagerModules.nixvim];
}

it throws the error message.

[nixos-discourse]

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

https://discourse.nixos.org/t/cannot-get-nixvim-to-install-as-a-module-in-home-manager/49643/2

[eclairevoyant]

However, if I put it somewhere in a file that is imported

It's because you didn't pass the top-level input into the module system via extraSpecialArgs; nixvim needs to come from somewhere, and you didn't provide it.

Only pkgs, lib, config, options, etc come for free, your custom args need to be provided explicitly.
