🚪 tobira.nvim

Learn the next Vim command from your own editing habits — not a cheat sheet.

tobira watches how you actually edit, and when it spots a pattern you could do better, it quietly shows you the one command that would have helped. No quizzes. No interruptions.

✨ Features

• 👀 Fully passive — reads keystrokes via vim.on_key(); no config required, zero impact on your existing mappings
• 🎯 38 detected patterns — repeated f, hammering j, dw→i instead of cw, insert-mode habits like <BS> spam or bouncing in and out with <Esc>i, and more across motion, edit, search, window, fold, mark, and macro
• 💬 One suggestion at a time — shown after a natural pause, capped per session, with a cooldown between auto-suggestions — never a popup quiz
• 📈 Mastery-aware — once you've used a command ~100 times, tobira stops suggesting it and moves on
• 🪜 Level-aware — beginner commands surface first, advanced ones once you're ready
• 🗺️ 149 commands in the learning graph, covering the full Neovim command surface

⚡️ Requirements

• Neovim 0.9+
• nvim-notify (optional — if installed, tobira's suggestion window matches its color scheme)

🚀 Usage

Command	Description
:Tobira	Show the next suggestion now (ignores cooldown). Press q / Esc to dismiss.
:TobiraGuide	Toggle the cheatsheet panel
:TobiraProgress	Show skill tree with mastery glyphs and a cursor-driven detail preview. x = suppress, p = pin, g/s = jump to guide/stats, q/Esc = close.
:TobiraStats	Show usage stats: command distribution (never/tried/familiar/mastered) and efficiency gap suggestions
:TobiraReset	Clear all usage data
:checkhealth tobira	Diagnose your install — Neovim version, data directory, usage.json validity, lang config

Full documentation is available in Neovim via :help tobira.

Guide panel

:TobiraGuide opens a cheatsheet on the right side of the screen. Commands you've already mastered are automatically hidden, so only your next targets are shown — and if one of them fades from use after you'd gotten comfortable with it, it reappears with a ⟳ (forgotten) marker instead of staying hidden forever. Pinned commands always appear at the top, marked ●. Covers all 7 categories: motion, edit, search, window, fold, mark, and macro — each capped to 3 unmastered commands (preferring ones you've never tried) so the panel stays a compact reference to glance at while you keep coding, with a +N more line if a category has more to show. Opens automatically on first launch.

Usage stats

:TobiraStats leads with the one section that actually changes what you do next — Try these next, commands you're using heavily whose neighbors you've never tried — followed by a mastery bar and your top commands. Total keystrokes and how many commands you've discovered sit in a quiet line at the bottom: fun to see, but not the point. g / p jump straight to Guide / Progress.

Skill progress

:TobiraProgress shows your current level and the full command learning graph as a calm grid — mastery glyphs only, no clutter. Move the cursor onto any command and a preview strip below the grid fills in with its usage sparkline, count, status, and how far it is from the next star. The header shows your overall {n} / {total} mastered ratio, and each category shows its own {done} / {total}.

Glyph	Meaning
(blank)	Not yet tried
☆	Tried (1+ uses)
★	Familiar (100+ uses)
★★	Practiced (1000+ uses)
★★★	Mastered (5000+ uses)
⟳	Forgotten — recent use has fallen off well below its earlier pace
✗	Suppressed — you don't want this suggested
●	Pinned — always shown, in both :TobiraGuide and :TobiraProgress

Keys inside :TobiraProgress: x toggles suppress on the command under the cursor, p toggles pin, g / s jump to Guide / Stats, q / Esc closes.

⚙️ Configuration

All options are optional — the defaults work out of the box.

require("tobira").setup({
  lang                = 'en',    -- 'en' | 'ja' | 'zh' | 'es' | 'fr' | 'de'
  idle_delay          = 1500,    -- ms of inactivity before showing an ambient suggestion
  idle_suggestions    = true,    -- enable ambient idle suggestions
  suggestion_cooldown = 300,     -- s between automatic suggestions (default: 5 min)
  max_shown           = 2,       -- max times to suggest the same command per session
})

❓ FAQ

Will tobira slow down my Neovim?

It is designed to stay passive and lightweight. tobira reads keystrokes with vim.on_key() and keeps the hot path minimal; it does not run file I/O for every keystroke. Usage data is flushed when Neovim exits.

Does it send my keystrokes anywhere?

No. tobira stores usage data locally in Neovim's data directory under tobira/usage.json. It does not upload your keystrokes or send them to a remote service.

Can I use it alongside hardtime.nvim?

Yes. hardtime.nvim blocks repeated habits, while tobira watches your normal editing and suggests what to learn next. They solve different parts of the same problem and can complement each other.

A suggestion keeps appearing even though I know the command. What should I do?

Open :TobiraProgress, move to the command, and press x to suppress it. You can also keep using the command normally; once it reaches the familiar threshold, tobira stops treating it as a beginner suggestion.

How do I reset my data?

Run :TobiraReset. This clears tobira's local usage data so suggestions start from a fresh profile.
