# Range control (Notchset): prompt.md (v2.0.0)

- id: `range-control` · version 2.0.0 · component · free
- category: Charts
- build: one set of files for every shadcn style
- install: `npx shadcn@latest add https://notchset.dev/r/range-control.json`
- npm dependencies: none
- registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json, @notchset/rolling-number, @notchset/segmented-control
- docs: https://notchset.dev/components/range-control
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

Day, Week, Month, 6M, Year and YTD as one switch with the period's headline above it: "Avg 6 h 51 · this week, +9 min against last week". The figure rolls only when the period changes, still with less motion; a period the data can't reach is left out..

## Build it
- Stack: React 18.3 or 19, TypeScript, Tailwind CSS v4 utility classes on the foundation's roles, a components.json (imports use its aliases).
- Packages: none beyond React.
- Files: `components/ui/notchset/range-control.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`, `rolling-number`, `segmented-control`.
- Builds: one set of files, the same for every shadcn style.
- Exports to keep: `RangeControl`, and every exported type.
- CSS: the install adds the notchset foundation (its roles, keyframes and motion switch, reading your shadcn tokens for colour) 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.
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- This item reads `--ns-font-display`, `--ns-ink`, `--ns-ink-2`, `--ns-ok-ink`, `--ns-text-hero`, `--ns-text-small`, `--ns-warn-ink`, `--ns-weight-strong`.
- Retune it (on any ancestor) with the foundation's roles and hooks: `--ns-bad`, `--ns-bad-ink`, `--ns-band`, `--ns-band-edge`, `--ns-band-grade`, `--ns-band-optimal`, `--ns-beat`, `--ns-bezel`, `--ns-canvas`, `--ns-cat-1`, `--ns-cat-2`, `--ns-cat-3`, `--ns-cat-4`, `--ns-cat-5`, `--ns-cat-6`, `--ns-check`, `--ns-chip`, `--ns-control`, `--ns-control-pad`, `--ns-control-sm`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-dialog`, `--ns-dialog-lg`, `--ns-dialog-sm`, `--ns-ease`, `--ns-ease-in`, `--ns-ease-panel`, `--ns-ease-pop`, `--ns-field`, `--ns-flood-arc`, `--ns-flood-aurora`, `--ns-flood-behind-1`, `--ns-flood-behind-2`, `--ns-flood-bloom`, `--ns-flood-deep`, `--ns-flood-dial-bloom`, `--ns-flood-glass`, `--ns-flood-grain`, `--ns-flood-image`, `--ns-flood-ink`, `--ns-flood-ink-low`, `--ns-flood-light`, `--ns-flood-mid`, `--ns-flood-pale`, `--ns-flood-pane`, `--ns-flood-pane-edge`, `--ns-flood-pill-ink`, `--ns-flood-ribbon`, `--ns-flood-ribbon-core`, `--ns-flood-shadow`, `--ns-flood-sheen`, `--ns-flood-wash`, `--ns-font-body`, `--ns-font-display`, `--ns-font-mono`, `--ns-font-script`, `--ns-glass`, `--ns-glass-blur`, `--ns-glass-shadow`, `--ns-glow`, `--ns-grain`, `--ns-gutter`, `--ns-header`, `--ns-heat`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-ink-4`, `--ns-leading`, `--ns-lift`, `--ns-light-1`, `--ns-light-2`, `--ns-light-3`, `--ns-light-spread`, `--ns-light-strength`, `--ns-line`, `--ns-line-soft`, `--ns-lit-edge`, `--ns-menu-dy`, `--ns-menu-row`, `--ns-mesh`, `--ns-mesh-frost`, `--ns-ok`, `--ns-ok-ink`, `--ns-orb-body`, `--ns-orb-cool`, `--ns-orb-core`, `--ns-orb-dawn`, `--ns-orb-deep`, `--ns-orb-edge`, `--ns-orb-grain`, `--ns-orb-ground`, `--ns-orb-halo`, `--ns-orb-inner`, `--ns-orb-key`, `--ns-orb-lift`, `--ns-orb-limb`, `--ns-orb-limb-from`, `--ns-orb-rim`, `--ns-orb-skin-hi`, `--ns-orb-skin-lo`, `--ns-orb-skin-mid`, `--ns-orb-warm`, `--ns-panel`, `--ns-panel-w`, `--ns-prism-edge`, `--ns-prism-glint`, `--ns-prism-sheen`, `--ns-prism-tint`, `--ns-pulse`, `--ns-radius`, `--ns-radius-card`, `--ns-radius-full`, `--ns-radius-lg`, `--ns-radius-sm`, `--ns-radius-xl`, `--ns-raised`, `--ns-range`, `--ns-row`, `--ns-row-compact`, `--ns-segment`, `--ns-selected`, `--ns-series`, `--ns-series-core`, `--ns-series-lilac`, `--ns-series-tint`, `--ns-shadow-dialog`, `--ns-shadow-float`, `--ns-shadow-panel`, `--ns-sheet`, `--ns-sheet-bottom`, `--ns-side`, `--ns-signal`, `--ns-sleep-awake`, `--ns-sleep-deep`, `--ns-sleep-light`, `--ns-sleep-rem`, `--ns-space-1`, `--ns-space-2`, `--ns-space-3`, `--ns-space-4`, `--ns-space-5`, `--ns-space-6`, `--ns-space-8`, `--ns-space-section`, `--ns-stack-on`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-switch-h`, `--ns-switch-w`, `--ns-text-body`, `--ns-text-control`, `--ns-text-display`, `--ns-text-figure`, `--ns-text-headline`, `--ns-text-hero`, `--ns-text-lede`, `--ns-text-meta`, `--ns-text-page`, `--ns-text-record`, `--ns-text-small`, `--ns-text-strong`, `--ns-text-sub`, `--ns-text-title`, `--ns-tile-shadow`, `--ns-time-born`, `--ns-time-color`, `--ns-time-dialog`, `--ns-time-menu`, `--ns-time-page`, `--ns-time-panel`, `--ns-time-toast`, `--ns-tint`, `--ns-tint-ink`, `--ns-toast-bottom`, `--ns-toast-left`, `--ns-touch`, `--ns-tracking-display`, `--ns-tracking-headline`, `--ns-warn`, `--ns-warn-ink`, `--ns-wash-clay`, `--ns-wash-dusk`, `--ns-wash-graphite`, `--ns-wash-ink`, `--ns-wash-sage`, `--ns-wash-sand`, `--ns-weight-light`, `--ns-weight-medium`, `--ns-weight-regular`, `--ns-weight-strong`, `--ns-well`.
- Never add Tailwind colour classes inside the component.

```tsx
import { RangeControl, type RangePeriod } from "@/components/ui/notchset/range-control";
```

## Parts
- A single export that takes props.

## Match the original
- Read `components/ui/notchset/range-control.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

### Not when

## Built from
- rolling-number (`rolling-number`), installed with it: reuse it, don't rebuild it
- segmented-control (`segmented-control`), installed with it: reuse it, don't rebuild it

## Mistakes
- Recreating the component instead of installing it

## Usage

```tsx
"use client";
import * as React from "react";
import { RangeControl, type RangePeriod } from "@/components/ui/notchset/range-control";

const FIG: Record<RangePeriod, [string, string, string]> = {
  day: ["6 h 57", "last night", "Through the night"],
  week: ["6 h 51", "this week", "+9 min against last week"],
  month: ["6 h 48", "this month", "+4 min against last month"],
  "6m": ["6 h 44", "the last 6 months", "−2 min against the 6 months before"],
  year: ["6 h 46", "this year", "Same as the year before"],
  ytd: ["6 h 47", "the year to date", "+1 min against last year to date"],
};

export default function RangeControlDemo() {
  const [p, setP] = React.useState<RangePeriod>("week");
  const [figure, words, delta] = FIG[p];
  return (
    <div className="max-w-[720px]">
      <RangeControl value={p} onValueChange={setP} figure={figure} words={words} delta={delta} tone={delta.startsWith("+") ? "ok" : "neutral"} />
    </div>
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `value` | `RangePeriod` |  | Required. |
| `onValueChange` | `(p: RangePeriod) => void` |  | Required. |
| `options` | `RangePeriod[]` | `["day", "week", "month", "6m", "year", "ytd"]` | the periods this metric can show, in order |
| `figure` | `string` |  | the period's figure, "6 h 51" |
| `unit` | `string` |  | its unit, small beside it |
| `lead` | `string` | `"Avg"` | the label before it, "Avg" |
| `words` | `string` |  | "this week" |
| `delta` | `string` |  | "+9 min against last week", or why there's none |
| `tone` | `"ok" \| "bad" \| "neutral"` | `"neutral"` | which way the delta reads: ok (better), bad (worse) or neutral |
| `label` | `string` | `"Time range"` | names the switch for a screen reader |

## Customising
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- Dark mode follows the `.dark` class or `data-theme="dark"` on an ancestor (the shadcn and next-themes conventions).
- Update later: Commit or stash local changes first (or copy the files), so the update can be undone. Read https://notchset.dev/r/changelog.json for the new versions: a major version, an entry marked breaking or a merge says what to change. Then re-run the install with `--overwrite`, on a branch. It replaces the component's files, the shared helper files they import, and the item's CSS rules in the global stylesheet, so review the whole diff (components, shared files, CSS), re-apply your own edits, and run the app's typecheck, tests and build.

## Accessibility contract (preserve when editing)

## Install

```bash
npx shadcn@latest add https://notchset.dev/r/range-control.json
```

Or add the `@notchset` registry to components.json and run `npx shadcn@latest add @notchset/range-control`. Every components.json style gets the same files.

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