Old Method

Prior to version 0.5, the method of adding new plugins was adding the plugin package to vim.startPlugins and add its configuration as a DAG under vim.configRC or vim.luaConfigRC. Users who have not yet updated to 0.5, or prefer a more hands-on approach may use the old method where the load order of the plugins is determined by DAGs.

Adding plugins

To add a plugin to neovim-flake's runtime, you may add it

{pkgs, ...}: {
  # add a package from nixpkgs to startPlugins
  vim.startPlugins = [
    pkgs.vimPlugins.aerial-nvim  ];
}

And to configure the added plugin, you can use the luaConfigRC option to provide configuration as a DAG using the neovim-flake extended library.

{inputs, ...}: let
  # assuming you have an input called neovim-flake pointing at the neovim-flake repo
  inherit (inputs.neovim-flake.lib.nvim.dag) entryAnywhere;
in {
  vim.luaConfigRC.aerial-nvim= entryAnywhere ''
    require('aerial').setup {
      -- your configuration here
    }
  '';
}
