You can add more neovim plugins to your Better Vim setup using lazy.nvim which is the default plugin manager for Better Vim. This guide shows you how to install any vim/neovim plugin using the plugin manager and the Better Vim modules.

​

1. Adding the plugin

The first step to install a plugin to your Better Vim config is add it to the plugins list. lazy.nvim uses Github to install and manage plugins. For example, if we want to install the todo-comments plugin we can change the entry plugins in better-vim.lua:

return {
  plugins = {
    "folke/todo-comments.nvim",
  },
}

You don’t need to pass the entire url of the repository, instead, we just pass the username/repository to the plugin manager. Usually, the installation instructions of the plugin show how to install the plugin using lazy.nvim and other package managers. If lazy.nvim is not present, the installation via Packer is pretty simmilar, with some differences that you can see here.

If the plugin has some dependencies, you can use the dependencies entry in the plugin table:

return {
  plugins = {
    "nvim-lua/plenary.nvim",
    { "folke/todo-comments.nvim", dependencies = "nvim-lua/plenary.nvim" },
  },
}

​

2. Setting up the plugin

Some plugins (like todo-comments) requires a setup or an initial config to work. You can do this using the entry config in the plugin table:

return {
  plugins = {
    "nvim-lua/plenary.nvim",
    {
      "folke/todo-comments.nvim",
      dependencies = "nvim-lua/plenary.nvim",
      config = function()
        require("todo-comments").setup {}
      end,
    },
  },
}

Using the .setup method is a common way to configure plugins in Vim from Lua. If .setup is the only function you need to call to setup your plugin, and/or pass some properties to it, instead of creating a new function, requiring the plugin and calling the .setup method, you can just use the entry opts instead:

return {
  plugins = {
    "nvim-lua/plenary.nvim",
    {
      "folke/todo-comments.nvim",
      dependencies = "nvim-lua/plenary.nvim",
      opts = {},
    },
  },
}

After all that, reopen your neovim and plugins will be installed asynchronously.

You can see all of them using the command :Lazy 🎉

​

Updating plugins

To update all your plugins, just run:

:Lazy sync

Or open the :Lazy interface and press Shift + S.

​

Uninstalling plugins

If you want to uninstall any plugin, remove the plugin from the plugins entry in better-vim.lua, reopen neovim and run this command inside Neovim:

:Lazy sync

After a new reopen, the plugin will be uninstalled. To cleanup removed plugins, you can type :Lazy to open Lazy interface, then press Shift + X, or just type :Lazy clean.
