== Home Manager

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

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

Followed by importing the HM module.

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

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

[source,nix]
----
{
  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;
      };
    };
  };
}
----

=== Custom vim/neovim plugins

It is possible to add custom plugins to your configuration by using the `vim.startPlugins` option and the this flake's lua DAG library. 

Start by adding it to startPlugins. This example uses nvim-surround, but the process will be similar for other plugins as well.

[source,nix]
----
{
  programs.neovim-flake = {
    enable = true;
    settings = {
      vim.startPlugins = [ pkgs.vimPlugins.nvim-surround ];
    };
  };
}
----

Followed by requiring the plugin, should it need one, in the lua DAG. Please note that you're able to name the DAG to however you want, the name will add a `--SECTION <name>` in the init.vim, under which it will be initialized. `lib.nvim.dag.entryAfter ["name"]` could also be used to initialize a plugin only after a previous plugin has beeni initialize
Your final setup will likely look like this, where nvim-flake refers to your flake input or fetch.

[source,nix]
----
{
  programs.neovim-flake = {
    enable = true;
    settings = {
      vim.startPlugins = [ pkgs.vimPlugins.nvim-surround ];
      luaConfigRC.nvim-surround = nvim-flake.lib.nvim.dag.entryAnywhere '' # nvim-flake is a reference to the flake. Please change this accordingly to your config.
        require("nvim-surround").setup()
      '';
    };
  };
}
