Make a backup of your current nvim folder if necessary:

mv ~/.config/nvim ~/.config/nvim.backup

Download neovim-lua with git and copy the nvim folder in the ${HOME}/.config directory:

git clone https://github.com/brainfucksec/neovim-lua.git
cd neovim-lua/
cp -Rv nvim ~/.config/

Install packer.nvim for install and manage the plugins:

git clone --depth 1 https://github.com/wbthomason/packer.nvim\

Run Neovim with PackerSync command:

nvim +PackerSync

LSP Configuration

sudo npm install -g bash-language-server pyright vscode-langservers-extracted typescript typescript-language-server

Install additional packages for plugins support:

C, C++:

clang for use LSP with clangd.
ctags to view tags with Tagbar.

Python:

pynvim

Open a source file of one of the supported languages with Neovim, and run command :LspInfo for testing the LSP support.

The color scheme is defined in the following files (default: OneDark):

Neovim UI - nvim/lua/core/settings.lua:

-- Load nvim color scheme:
...color_scheme = pcall(require, 'onedark')
require('onedark').setup {
    style = 'darker'
}
require('onedark').load()

Statusline - nvim/lua/plugins/feline.lua:

-- Set colorscheme (from core/colors.lua/colorscheme_name)
local colors = require('core/colors').onedark_dark

Configuration check

Open nvim and run command checkhealth, you should not see any error in the output (except for the one related to the Python 2 interpreter if don’t have it):

:checkhealth

You can also use the startuptime option to read the nvim startup logs:

nvim --startuptime > /tmp/nvim-start.log

nvim /tmp/nvim-start.log

Disclaimer

As all my setups I try to follow the KISS principle, probably some concepts may not be valid for everyone. Then feel free to take what you need but don’t install anything without checking first!

Thanks to all the authors of the sources mentioned above, to all the others from whom I “stole” some configs and thanks to the users of /r/Neovim subreddit for the support of the configuration :)
