My own user-contributed packages as proposed in nix-community/NUR.

By importing ./nur-packages/nur, the NUR will be available as:

• config.nur option for the global NUR with the local override (it is safe to use if online)
• config.nurLocal option for the local NUR only (it is safe to use if offline)

In the first case, the rychly NUR repository is available locally and all other NUR repositories are fetched from the GIT NUR master branch. Also, all modules from the rychly NUR repository will be imported automatically.

{ ... }:

{

  imports = [
    ./nur-packages/nur
  ];

}

You can also add and use NUR as described in the docs.

After the importing NUR as described above, the NUR is available in modules via config.nur and config.nurLocal options.

There are several overlays available that can be imported with an expression like this:

{ config, ... }:

let

  overlays-custom = config.nurLocal.repos.rychly.overlays;

in {

  nixpkgs.overlays = [
    overlays-custom.<overlay-name>
  ];

}

After the importing NUR as described above, all modules from rychly NUR repository will be imported automatically.
