# Task row (Notchset): prompt.md (v2.1.0)

- id: `task-row` · version 2.1.0 · block · pro (Pro)
- category: Data
- build: one set of files for every shadcn style
- install: `npx shadcn@latest add @notchset-pro/task-row`
- npm dependencies: none
- registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json, @notchset/checkbox, @notchset/status-glyph
- docs: https://notchset.dev/blocks/task-row
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

One task on one line: its status glyph (which finishes it), the title with its small marks, then only the columns the page doesn't already say, and when it's due, late in the error colour. Selection is plain, the keyboard's row ringed in ink; the host binds J, K, X and Enter..

## 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/blocks/task-row.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`, `checkbox`, `status-glyph`.
- Builds: one set of files, the same for every shadcn style.
- Exports to keep: `TaskMark`, `TaskRow`, 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-bad-ink`, `--ns-font-mono`, `--ns-gutter`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-line-soft`, `--ns-row`, `--ns-row-compact`, `--ns-selected`, `--ns-text-meta`, `--ns-text-small`, `--ns-time-color`, `--ns-warn`.
- 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 { TaskMark, TaskRow } from "@/components/ui/notchset/blocks/task-row";
```

## Parts
- A single export that takes props.

## Match the original
- Read `components/ui/notchset/blocks/task-row.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
- checkbox (`checkbox`), installed with it: reuse it, don't rebuild it
- status-glyph (`status-glyph`), 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 { MessageSquare } from "lucide-react";
import { TaskMark, TaskRow } from "@/components/ui/notchset/blocks/task-row";
import type { TaskStatus } from "@/components/ui/notchset/status-glyph";

const TASKS = [
  { id: "RP-49", title: "Recalculate ETA when a job runs long", status: "review" as TaskStatus, due: "Yesterday", late: true, comments: 4 },
  { id: "RP-57", title: "Undo for route edits", status: "doing" as TaskStatus, due: "Today", late: false, comments: 0 },
  { id: "RP-60", title: "Explain why a stop moved", status: "todo" as TaskStatus, due: "Oct 27", late: false, comments: 1 },
];

export default function TaskRowDemo() {
  const [tasks, setTasks] = React.useState(TASKS);
  const [sel, setSel] = React.useState<string[]>([]);
  const [open, setOpen] = React.useState<string | null>(null);
  return (
    <div className="w-full max-w-[720px]">
      {tasks.map((t) => (
        <TaskRow
          key={t.id}
          id={t.id}
          code={t.id}
          title={t.title}
          status={t.status}
          due={t.status === "done" ? "Done today" : t.due}
          late={t.late && t.status !== "done"}
          meta={t.comments ? <TaskMark icon={<MessageSquare aria-hidden />}>{t.comments}</TaskMark> : undefined}
          context={<span className="truncate">Route planner v2</span>}
          active={open === t.id}
          selected={sel.includes(t.id)}
          onSelect={() => setSel((s) => (s.includes(t.id) ? s.filter((x) => x !== t.id) : [...s, t.id]))}
          onOpen={() => setOpen(t.id)}
          onComplete={() => setTasks((ts) => ts.map((x) => (x.id === t.id ? { ...x, status: "done" } : x)))}
        />
      ))}
      <p className="m-0 px-[var(--ns-gutter)] pt-2 text-[length:var(--ns-text-small)] text-[var(--ns-ink-3)]">{open ? `Opened ${open}` : sel.length ? `${sel.length} selected` : "Tick a glyph to finish a task"}</p>
    </div>
  );
}
```

This example also uses the npm package `lucide-react`. Installing this item doesn't bring them; to paste the example as it is: `npx shadcn@latest add @notchset-pro/task-row`. The `@notchset-pro` items are Pro: they need the registries in components.json and the key (Setup).

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `id` | `string` |  | Required. |
| `title` | `string` |  | Required. |
| `status` | `TaskStatus` |  | Required. |
| `onOpen` | `() => void` |  | Required. |
| `onComplete` | `() => void` |  |  |
| `code` | `string` |  | the task's key shown before the title ("RP-49"), when the page lists many projects' work |
| `meta` | `React.ReactNode` |  | small marks after the title: repeats, subtasks, comments, blocked |
| `context` | `React.ReactNode` |  | where it belongs (a project), quiet, after the title |
| `cells` | `React.ReactNode` |  | further columns, each sized by its own class (a status, an assignee, a priority) |
| `due` | `string` |  |  |
| `late` | `boolean` |  |  |
| `selected` | `boolean` |  | shows the select box; selected rows are plain, never the Signature |
| `onSelect` | `(additive: boolean) => void` |  |  |
| `active` | `boolean` |  | the row the keyboard is on |
| `density` | `"comfortable" \| "compact"` | `"comfortable"` |  |
| `landed` | `boolean` |  | a row you just made or moved: marked where it landed, once |
| `onContextMenu` | `(e: React.MouseEvent) => void` |  |  |

## 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 @notchset-pro/task-row
```

Pro item: needs the `@notchset-pro` registry in `components.json` and `NOTCHSET_TOKEN` in `.env.local` (https://notchset.dev/account). Setup: https://notchset.dev/docs/pro. 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.
