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

Universal Server & System Editing: Editing system configs, scripts, and code on any Unix/Linux server without installing external software.
Modal Text Manipulation: Composing text transformations with operator-motion grammar (dap, ci", gUiw).
Headless Macro Automation: Recording and replaying repetitive editing operations across hundreds of lines (qa, @a).
Git Commit & Merge Editing: Fast interactive editing for commit messages, interactive rebases, and diff conflict resolution.
