# Toolbar (Notchset): prompt.md (v1.0.0)

- id: `toolbar` · version 1.0.0 · component · pro (Pro)
- category: Actions
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/toolbar`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/toolbar
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

Icon keys joined in an ink frame on a plate. A press fills the key with ink and drops its icon a pixel; each tooltip drops on a leader line to an ink tag with its shortcut, after 390ms on hover and 90ms on keyboard focus.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/notchset/toolbar.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `MoreGlyph`, `Toolbar`, `ToolbarKey`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { MoreGlyph, Toolbar, ToolbarKey } from "@/components/ui/notchset/toolbar";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `Toolbar` | `toolbar` | The joined keys. |
| `ToolbarKey` | `toolbar-key` | One icon key. |
| `Tooltip` | `toolbar-tooltip` | The ink tag under a key. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/toolbar.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- toolbar, icon buttons, action bar, icon keys, tooltip shortcuts, Notchset
- A row of actions on one object: re-run, open, copy, share

### Not when
- Text actions: use buttons

## Mistakes
- Label every key: the tooltip shows the same words

## Usage

```tsx
"use client";

import { MoreGlyph, Toolbar, ToolbarKey } from "@/components/ui/notchset/toolbar";

export function RunToolbar({ rerun, more }: { rerun: () => void; more: () => void }) {
  return (
    <Toolbar legend="RUN_8F3A1 · ACTIONS" aria-label="Run actions">
      <ToolbarKey label="Re-run" kbd="R" icon={<span aria-hidden>↻</span>} onClick={rerun} />
      <ToolbarKey label="More" icon={<MoreGlyph />} separated onClick={more} />
    </Toolbar>
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `legend` | `string` |  | The legend above the toolbar; its node flashes on any press. |
| `aria-label` | `string` |  | Names the toolbar. |
| `ToolbarKey label` | `string` |  | The key's name and tooltip. |
| `ToolbarKey kbd` | `string` |  | The shortcut in the tooltip (display; set aria-keyshortcuts for single keys). |
| `ToolbarKey icon` | `ReactNode` |  | A 16px icon. |
| `ToolbarKey separated` | `boolean` |  | An ink divider before this key. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| ← → | Move between keys |
| Home / End | First or last key |
| Enter / Space | Press |

## Performance

- One roving tab stop; keys are plain buttons with CSS transitions.

## Responsive

- Keys keep their size; the toolbar scrolls horizontally rather than wrap on narrow screens.
- 44px keys on touch screens.

## Motion inventory

| Interaction | What moves |
|---|---|
| Press | Ink fill; the icon drops 1px and scales to .9 in 40ms, springing back over 240ms |
| Tooltip | The leader draws (scaleY) after 300ms on hover; the tag fades and drops 3px after 390ms (90ms on focus) |

## Accessibility contract (preserve when editing)
- role=toolbar with roving tabindex; every key has aria-label
- Tooltips are visual; the name is the key's label

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/toolbar
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
