Vim

Vim is the universal text editor installed on every UNIX system. While Neovim innovates, Vim focuses on backward compatibility and stability.

When to Use

• SSH / Servers: It is always there. vi usually aliases to vim.
• Stability: Scripts written in 2005 still work.
• Resource Constraints: Runs on embedded routers.

Core Concepts

Modes

• Normal: Navigation (hjkl).
• Insert: Typing (i, a).
• Visual: Selection (v).
• Command: Ex commands (:w, :q).

Composability

Operator + Motion = Action. d (delete) + w (word) = dw. c (change) + i (inside) + " (quote) = ci".

Best Practices (2025)

Do:

• Learn the Basics: vimtutor is mandatory for every developer.
• Use .vimrc: Keep a minimal config for servers (line numbers, syntax on).
• Use Neovim for IDE: For daily coding, Neovim is preferred. Use Vim for quick edits.

Don't:

• Don't use arrow keys: Force yourself to use hjkl.
