Preface

If your problem is caused by a bug in neovim-flake then it should be reported on the neovim-flake issue tracker. Alongside bug reports, feature requests are also welcome over neovim-flake pull requests.

Chapter 1. Try it out

$ cachix use neovim-flake # Optional: it'll save you CPU resources and time
$ nix run github:notashelf/neovim-flake

1.1. Nix

By default LSP support for Nix is enabled alongside all complementary Neovim plugins. By running nix run ., which is the default package, you will build Neovim with this config.

1.2. Tidal

Tidal is an alternative config that adds vim-tidal on top of the plugins from the Nix configuration.

1.3. Maximal

Maximal is the ultimate configuration that will enable basically everything. Keep in mind, however, that this will pull a lot of dependencies.

You are strongly recommended to use the binary cache if you would like to try the Maximal configuration.

1.4. Using Prebuilt Configs

$ nix run github:notashelf/neovim-flake#nix
$ nix run github:notashelf/neovim-flake#tidal
$ nix run github:notashelf/neovim-flake#maximal

Chapter 2. Default Configs

While you can configure neovim-flake yourself using the builder, here are a few default configurations you can use.

2.1. Tidal Cycles

$ nix run github:notashelf/neovim-flake#tidal file.tidal

Utilizing vim-tidal and mitchmindtree’s fantastic tidalcycles.nix start playing with tidal cycles in a single command.

In your tidal file, type a cycle e.g. d1 $ s "drum" and then press ctrl+enter. Super collider with superdirt, and a modified GHCI with tidal will start up and begin playing. Note, you need jack enabled on your system. If you are using pipewire, its as easy as setting services.pipewire.jack.enable = true.

2.2. Nix

$ nix run github:notashelf/neovim-flake#nix test.nix

Enables all the of neovim plugins, with language support for specifically Nix. This lets you see what a fully configured neovim setup looks like without downloading a whole bunch of language servers and associated tools.

2.3. Maximal

$ nix shell github:notashelf/neovim-flake#maximal test.nix

It is the same fully configured neovim as with the Nix config, but with every supported language enabled.

Note

Running the maximal config will download a lot of packages as it is downloading language servers, formatters, and more.

Chapter 3. Custom Configuration

Custom configuration is done with the neovimConfiguration function. It takes in the configuration as a module. The output of the configuration function is an attrset.

{
  options = "The options that were available to configure";
  config = "The outputted configuration";
  pkgs = "The package set used to evaluate the module";
  neovim = "The built neovim package";
}

The following is an example of a barebones vim configuration with the default theme enabled.

{
  inputs.neovim-flake = {
    url = "github:notashelf/neovim-flake";
    inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = {nixpkgs, neovim-flake, ...}: let
    system = "x86_64-linux";
    pkgs = nixpkgs.legacyPackages.${system};
    configModule = {
      # Add any custom options (and feel free to upstream them!)
      # options = ...

      config.vim = {
        theme.enable = true;
      };
    };

    customNeovim = neovim-flake.lib.neovimConfiguration {
      modules = [configModule];
      inherit pkgs;
    };
  in {
    packages.${system}.neovim = customNeovim.neovim;
  };
}

Chapter 4. Home Manager

The Home Manager module allows us to customize the different vim options. To use it, we first add the input flake.

{
  neovim-flake = {
    url = github:notashelf/neovim-flake;
    # you can override input nixpkgs
    inputs.nixpkgs.follows = "nixpkgs";
  };
}

Followed by importing the HM module.

{
  imports = [ neovim-flake.homeManagerModules.default ];
}

Then we should be able to use the given module. E.g.

{
  programs.neovim-flake = {

    enable = true;
    # your settings need to go into the settings attrset
    settings = {
      vim.viAlias = false;
      vim.vimAlias = true;
      vim.lsp = {
        enable = true;
      };
    };
  };
}

Chapter 5. Language Support

Language specific support means there is a combination of language specific plugins, treesitter support, nvim-lspconfig language servers, and null-ls integration. This gets you capabilities ranging from autocompletion to formatting to diagnostics. The following languages have sections under the vim.languages attribute. See the configuration docs for details.

Adding support for more languages, and improving support for existing ones are great places where you can contribute with a PR.
