Neovim

Neovim is the future of Vim. v0.11 (2025) brings built-in completion, enhanced LSP, and mature Tree-sitter integration.

When to Use

• Keyboard Centric: You never want to touch the mouse.
• Speed: You want an editor that starts in 20ms.
• Customization: You want to build your own editor using Lua.

Core Concepts

Lua Config (init.lua)

Configuration is code. Modules, loops, conditionals. vim.opt.number = true

LSP (Language Server Protocol)

Built-in client. Connects to pyright, tsserver, rust-analyzer natively.

Tree-sitter

Parsing library for syntax highlighting. Understanding code structure (AST), not just Regex.

Best Practices (2025)

Do:

• Use a Distro (Optional): LazyVim, AstroNvim, or NvChad are great starting points for 2025.
• Use lazy.nvim: The standard plugin manager.
• Use Built-ins: v0.11 has many features (commenting, diagnostics) that used to need plugins. Check :help news.

Don’t:

• Don’t copy huge configs: Understand every line you add to init.lua.
