Neovim Configuration from Scratch: init.lua, Keymaps & Autocmds | Episode 6

Описание: Build a modular Neovim configuration from scratch using pure Lua — no plugins needed! In Episode 6, we create init.lua as the entry point,
organize settings into separate modules with require(), and configure options, keymaps, and autocommands. Every setting is tested live so you
can see exactly what changes.

Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace.

What You'll Learn:
Config structure: init.lua entry point with require() loading modules from lua/
vim.g.mapleader: Set leader key (Space) before any leader mappings
vim.opt.number / relativenumber: Line numbers that show jump distance
vim.opt.tabstop / shiftwidth / expandtab: Control indentation (4 spaces)
vim.opt.ignorecase / smartcase: Case-insensitive unless you type uppercase
vim.opt.wrap / scrolloff: No wrapping, keep 8 lines of context
vim.opt.clipboard / undofile: System clipboard sharing, persistent undo
vim.keymap.set: Create keybindings with mode, key, action, and opts
Leader keymaps: Space+w save, Space+q quit, Escape clear search highlight
Scroll centering: Ctrl+d/u with zz keeps cursor centered on screen
Visual mode line moving: J/K to move selected lines up/down as a block
Split management: Leader+sv vertical, Leader+sh horizontal
nvim_create_autocmd("TextYankPost"): Flash highlight on yanked text
nvim_create_autocmd("BufWritePre"): Auto-trim trailing whitespace on save
nvim_create_autocmd("FileType"): Per-language settings (2-space indent for Lua)

Key Takeaways:
1. init.lua is the entry point — require() loads modules from lua/
2. vim.opt controls settings: numbers, tabs, search, clipboard
3. Set mapleader before defining any leader mappings
4. vim.keymap.set(mode, key, action, opts) creates bindings
5. nvim_create_autocmd(event, {callback}) automates actions on events

This is Episode 6 of the Neovim Tutorial Series. Episode 5 covers substitution and global commands. Next episode introduces plugin management
with lazy.nvim.
