Neovim is an hyperextensible Vim-based text editor

Steps

Installation

To install Neovim here you will find the ways to install Neovim according to your system.

I will use homebrew to install Neovim.

Configuration

Create the directory:

mkdir -p ~/.config/nvim

The folder structure

This is the folder structure we will use:

├── init.lua

    └── <YOUR_NAME>
        ├── core                -> The directory with basis configuration
        ├── plugins             -> The directory with custom plugin configuration
        └── plugins-setup.lua   -> The list of plugins

Setup the options

Create the options.lua file:

vim ~/.config/nvim/lua/<YOUR_NAME>/core/options.lua

Add the following options:

local opt = vim.opt

-- line numbers
opt.relativenumber = true
opt.number = true

-- tabs & indentation
opt.tabstop = 2
opt.shiftwidth = 2
opt.expandtab = true

-- add - as word
opt.iskeyword:append("-")

opt.lazyredraw = true

Setup the plugins

Create the plugins-setup.lua file:

touch ~/.config/nvim/lua/<YOUR_NAME>/plugins-setup.lua
