How to configure Neovim for Windows 11 by using init.lua

Configuration Neovim by using init.lua on Windows 11

1. Create file init.lua in C:\Users\your_name\AppData\Local\nvim\init.lua

2. Add to file init.lua parameters for tabs (for Python I use 4 spaces for identation):
  vim.cmd("set expandtab")
  vim.cmd("set tabstop=4")
  vim.cmd("set softtabstop=4")
  vim.cmd("set shiftwidth=4")
 
3. Add to init.lua configuration for lazy.nvim package manager
https://lazy.folke.io/installation
https://github.com/folke/lazy.nvim?tab=readme-ov-file

4. Set color scheme:
https://github.com/catppuccin/nvim

5. Install lua (required for lazy.nvim):

6. Install, symilarly, luarocks
https://github.com/luarocks/luarocks/wiki/Installation-instructions-for-Windows

7. Add configuration for Telescope:
https://github.com/nvim-telescope/telescope.nvim

8. Add configuration for nvim-treesitter
https://github.com/nvim-treesitter/nvim-treesitter/wiki/Installation

9. Install C compiler for "nvim-treesitter" I'v installed "Mingw toolchain"
https://github.com/nvim-treesitter/nvim-treesitter/wiki/Windows-support

10. Install neo-tree and add shortcut Ctrl-n to open filetree
https://github.com/nvim-neo-tree/neo-tree.nvim
-- shortcut for neo-tree
vim.keymap.set('n', '<C-n>', ':Neotree filesystem reveal left<CR>', { desc = '' }) -- opening filetree Ctrl + n

init.lua

vim.cmd("set expandtab")
vim.cmd("set tabstop=4")
vim.cmd("set softtabstop=4")
vim.cmd("set shiftwidth=4")
vim.g.mapleader = " " --sets <leader> key as a space

-- Bootstrap lazy.nvim
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
  local lazyrepo = "https://github.com/folke/lazy.nvim.git"
  local out = vim.fn.system({ "git", "clone", "--filter=blob:none", "--branch=stable", lazyrepo, lazypath })
  if vim.v.shell_error ~= 0 then
    vim.api.nvim_echo({
      { "Failed to clone lazy.nvim:\n", "ErrorMsg" },
      { out, "WarningMsg" },
      { "\nPress any key to exit..." },
    }, true, {})
    vim.fn.getchar()
    os.exit(1)
  end
end
vim.opt.rtp:prepend(lazypath)

-- Make sure to setup `mapleader` and `maplocalleader` before
-- loading lazy.nvim so that mappings are correct.
-- This is also a good place to setup other settings (vim.opt)
vim.g.mapleader = " "
vim.g.maplocalleader = "\\"

-- Setup lazy.nvim

local configs = require("nvim-treesitter.configs")
configs.setup({

})


-- shortcuts for Telescope
local builtin = require('telescope.builtin')
vim.keymap.set('n', '<C-p>', builtin.find_files, { desc = 'Telescope find files' }) -- set shortcut Ctrl + p
vim.keymap.set('n', '<leader>fg', builtin.live_grep, { desc = 'Telescope live grep' }) -- call command live_grep after writting '<leader>fg'

-- shortcut for neo-tree

-- set colorscheme
require("catppuccin").setup()
vim.cmd.colorscheme "catppuccin"
