Pure Lua Configuration

We recognize that you might not always want to configure your setup purely in Nix, sometimes doing things in Lua is simply the "superior" option. In such a case you might want to configure your Neovim instance using Lua, and nothing but Lua. It is also possible to mix Lua and Nix configurations through the following method.

Custom Configuration Directory

As of Neovim 0.9, {var}$NVIM_APPNAME is a variable expected by Neovim to decide on the configuration directory. nvf sets this variable as "nvf", meaning ~/.config/nvf will be regarded as the configuration directory by Neovim, similar to how ~/.config/nvim behaves in regular installations. This allows some degree of Lua configuration, backed by our low-level wrapper mnw. Creating a lua/ directory located in $NVIM_APPNAME ("nvf" by default) and placing your configuration in, e.g., ~/.config/nvf/lua/myconfig will allow you to require it as a part of the Lua module system through nvf's module system.

Let's assume your ~/.config/nvf/lua/myconfig/init.lua consists of the following:

-- init.lua
vim.keymap.set("n", " ", "<Nop>", { silent = true, remap = false })
vim.g.mapleader = " "

The following Nix configuration via will allow loading this

{
  # The attribute name "myconfig-dir" here is arbitrary. It is required to be
  # a *named* attribute by the DAG system, but the name is entirely up to you.
  vim.luaConfigRC.myconfig-dir = ''
    require("myconfig")

    -- Any additional Lua
  '';
}

After you load your custom configuration, you may use an init.lua located in your custom configuration directory to configure Neovim exactly as you would without a wrapper like nvf. If you want to place your require call in a specific position (i.e., before or after options you set in nvf) the DAG system will let you place your configuration in a location of your choosing.
