kanagawa colour scheme

[LaughingBubba]

Hi I'm trying to figure out how setup kanagawa colour scheme in nixvim.

There is a nix package for it: https://search.nixos.org/packages?channel=23.05&show=vimPlugins.kanagawa-nvim&from=0&size=50&sort=relevance&type=packages&query=kanagawa

I got gruvbox scheme working with a one liner in the default.nix file but kanagawa is eluding me.

flake.nix

{
  description = "A nixvim configuration";

  inputs = {
    nixvim.url = "github:pta2002/nixvim";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = {
    nixpkgs,
    nixvim,
    flake-utils,
    ...
  } @ inputs: let
    config = import ./config; # import the module directly
  in
    flake-utils.lib.eachDefaultSystem (system: let
      nixvimLib = nixvim.lib.${system};
      pkgs = import nixpkgs {inherit system;};
      nixvim' = nixvim.legacyPackages.${system};
      nvim = nixvim'.makeNixvimWithModule {
        inherit pkgs;
        module = config;
      };
    in {
      checks = {
        # Run `nix flake check .` to verify that your config is not broken
        default = nixvimLib.check.mkTestDerivationFromNvim {
          inherit nvim;
          name = "A nixvim configuration";
        };
      };
     ### ADDED 
      programs.nixvim = {
        extraPlugins = [ pkgs.vimPlugins.kanagawa-nvim ];
        colorscheme = "kanagawa-nvim";
      };
     ###
      packages = {
        # Lets you run `nix run .` to start nixvim
        default = nvim;
      };
    });
}

./config/default.nix

{
  # Import all your configuration modules here
  imports = [
    ./bufferline.nix
  ];
  #colorschemes.gruvbox.enable = true;

 ### Doesn't recognise scheme
  #colorschemes.kanagawa-nvim.enable = true;
}

Hi !
This is normal. Indeed, nixvim supports a few colorschemes for which we have wrapped the options.
It is not because one colorscheme plugin (or any vim plugin in general) is packages in nixpkgs that it is wrapped in nixvim.
You can, however, add any plugin packaged in nixpkgs in the nixvim.extraPlugins list.

I made a PR to add support for kanagawa though :)

To expand a little. This would work if you put it in the config, and you're also calling the colorscheme by the wrong name.

You can take the added part out of flake.nix and ./config/default.nix would look like:

{ pkgs, ... }:
{
  imports = [
    ./bufferline.nix
  ];
  extraPlugins = with pkgs; [ vimPlugins.kanagawa-nvim ];
  colorscheme = "kanagawa";
}

Thank you @siph for adding this precision.
The PR should be merged soon, so once merged, you will be able to simply set colorschemes.kanagawa.enable = true (and configure it if you wish).

Thanks for the prompt response. I cycled through a number of variations before posting which included "kanagawa" as the colorscheme. If figured I was missing something because programs wasn't declared anywhere and yet the README.md had programs.nixvim

The suggested code works just dandy thanks and thanks @GaetanLepage for the PR as well.

If you're making a standalone flake you won't need to use programs, that's for using it as a module in nixos or home-manager

@LaughingBubba the PR has just been merged ! If you are satisfied with the solution, could you please mark this thread as solved ?
