NixOS Module

The NixOS module allows us to customize the different vim options from inside the NixOS configuration without having to call for the wrapper yourself. It is the recommended way to use nvf alongside the home-manager module depending on your needs.

To use it, we first add the input flake.

{
  inputs = {
    obsidian-nvim.url = "github:epwalsh/obsidian.nvim";
    nvf = {
      url = "github:notashelf/nvf";
      # you can override input nixpkgs
      inputs.nixpkgs.follows = "nixpkgs";
      # you can also override individual plugins
      # for example:
      inputs.obsidian-nvim.follows = "obsidian-nvim"; # <- this will use the obsidian-nvim from your inputs
    };
  };
}

Followed by importing the NixOS module somewhere in your configuration.

{
  # assuming nvf is in your inputs and inputs is in the argset
  # see example below
  imports = [ inputs.nvf.nixosModules.default ];
}

Example Installation

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nvf.url = "github:notashelf/nvf";
  };

  outputs = { nixpkgs, nvf, ... }: let
  system = "x86_64-linux"; in {
    # ↓ this is your host output in the flake schema
    nixosConfigurations."yourUsername»" = nixpkgs.lib.nixosSystem {
      modules = [
        nvf.nixosModules.default # <- this imports the NixOS module that provides the options
        ./configuration.nix # <- your host entrypoint
      ];
    };
  };
}

Once the module is properly imported by your host, you will be able to use the programs.nvf module option anywhere in your configuration in order to configure nvf.

  programs.nvf = {
    enable = true;
    # your settings need to go into the settings attribute set
    # most settings are documented in the appendix
    settings = {
      vim.viAlias = false;
      vim.vimAlias = true;
      vim.lsp = {
        enable = true;
      };
    };
  };
}

::: {.note}

nvf exposes a lot of options, most of which are not referenced in the installation sections of the manual. You may find all available options in the appendix
