Use it when writing, debugging, or updating interactive CLI prompts, spinners, progress, and cancellation flows. **Install:** ```bash npx degit https://github.com/skilld-dev/skilld/tree/main/.claude/skills/bombshell-dev-clack ~/.claude/skills/bombshell-dev-clack ``` ## README # bombshell-dev/clack `@clack/prompts` **Version:** 1.0.1 (yesterday) **Deps:** picocolors@^1.0.0, sisteransi@^1.0.5, @clack/core@1.0.1 **Tags:** alpha: 1.0.0-alpha.10 (2 weeks ago), latest: 1.0.1 (yesterday) **References:** [package.json](./.skilld/pkg/package.json) • [README](./.skilld/pkg/README.md) • [GitHub Issues](./.skilld/issues/_INDEX.md) • [Releases](./.skilld/releases/_INDEX.md) ## Search Use `npx -y skilld search` instead of grepping `.skilld/` directories — hybrid semantic + keyword search across all indexed docs, issues, and releases. ```bash npx -y skilld search "query" -p @clack/prompts npx -y skilld search "issues:error handling" -p @clack/prompts npx -y skilld search "releases:deprecated" -p @clack/prompts ``` Filters: `docs:`, `issues:`, `releases:` prefix narrows by source type. ## API Changes ⚠️ **ESM-only** — v1.0 dropped CJS dual-publish, `require('@clack/prompts')` no longer works [source](./.skilld/releases/@clack/prompts@1.0.0.md) ⚠️ `spinner.stop(msg, 1)` / `spinner.stop(msg, 2)` — v1.0 replaced numeric codes with `spinner.cancel(msg)` and `spinner.error(msg)` [source](./.skilld/releases/@clack/prompts@1.0.0.md) ⚠️ `suggestion` prompt — added then removed in v1.0, use `path` prompt (autocomplete-based) instead [source](./.skilld/releases/@clack/prompts@1.0.0.md) ⚠️ `placeholder` in `text()` — v1.0 changed to visual-only hint, no longer used as tabbable/return value [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `autocomplete()` / `autocompleteMultiselect()` — new in v1.0, searchable select with `filter` option for custom/fuzzy matching [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `progress()` — new in v1.0, displays a progress bar with `start()`, `stop()`, `cancel()`, `error()` methods [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `taskLog()` — new in v1.0, scrolling log output cleared on success; supports `group()` for nested log sections [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `box()` — new in v1.0, renders boxed text similar to `note` [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `path()` — new in v1.0, autocomplete-based file path prompt [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `stream.step()` — new in v0.10, renders async iterable message streams (useful for LLM output) [source](./.skilld/releases/@clack/prompts@0.10.0.md) ✨ `spinner({ indicator: 'timer' })` — new in v0.10, shows elapsed time instead of dots animation [source](./.skilld/releases/@clack/prompts@0.10.0.md) ✨ `updateSettings({ aliases, messages })` — new in v0.9, configures global keybindings and i18n cancel/error messages [source](./.skilld/releases/@clack/prompts@0.9.0.md) ✨ `signal` option — new in v0.9, all prompts accept `AbortSignal` for programmatic cancellation [source](./.skilld/releases/@clack/prompts@0.9.0.md) ✨ `withGuide` option — new in v1.0, disables the default clack border on any prompt [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `spinner.clear()` — new in v1.0, stops and clears spinner output entirely [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✨ `confirm({ vertical: true })` — new in v1.0.1, arranges yes/no options vertically [source](./.skilld/releases/@clack/prompts@1.0.1.md) ## Best Practices ✅ Use `spinner.cancel()` and `spinner.error()` instead of stop codes — v1.0 replaced `stop(msg, code)` with distinct methods [source](./.skilld/releases/@clack/prompts@1.0.0.md) ```ts const s = spinner() s.start('Deploying') // s.stop('Done') // success // s.cancel('Aborted') // user cancelled (CTRL+C) // s.error('Failed') // error occurred // s.clear() // stop and clear all output ``` ✅ Pass `signal` to prompts for programmatic cancellation — all prompts accept `AbortSignal` since v0.9.0 [source](./.skilld/releases/@clack/prompts@0.9.0.md) ```ts const answer = await confirm({ message: 'Continue?', signal: AbortSignal.timeout(5000), }) ``` ✅ Use `group()` with `onCancel` instead of checking `isCancel` after every prompt — centralizes cancellation handling for multi-step flows [source](./.skilld/pkg/README.md) ```ts const result = await p.group({ name: () => p.text({ message: 'Name?' }), lang: () => p.select({ message: 'Language?', options }), }, { onCancel: () => { p.cancel('Cancelled.'); process.exit(0) }, }) ``` ✅ Use `updateSettings` for global i18n messages and key aliases — per-instance options override globals [source](./.skilld/releases/@clack/prompts@1.0.0.md) ```ts import { updateSettings } from '@clack/prompts' updateSettings({ aliases: { w: 'up', s: 'down' }, messages: { cancel: 'Cancelado', error: 'Error' }, }) ``` ✅ Use `stream` instead of `log` for LLM/async output — accepts sync and async iterables, renders incrementally [source](./.skilld/releases/@clack/prompts@0.10.0.md) ```ts await stream.step((async function* () { yield* generateLLMResponse(question) })()) ``` ✅ Use `taskLog` for subprocess output — renders lines continuously, clears on success, preserves on error [source](./.skilld/pkg/README.md) ```ts const tl = taskLog({ title: 'Building' }) for await (const line of buildProcess()) tl.message(line) success ? tl.success('Done') : tl.error('Failed') ``` ✅ Distinguish `placeholder` from `defaultValue` in `text()` — placeholder is visual-only hint, never returned as value (changed in v1.0); use `defaultValue` for the fallback return value [source](./.skilld/issues/issue-321.md) ```ts const name = await text({ message: 'Project name?', placeholder: 'my-app', // visual hint only, NOT returned defaultValue: 'my-app', // returned when user presses Enter without typing }) ``` ✅ v1.0 is ESM-only — CJS `require()` no longer works; use dynamic `import()` or switch to ESM [source](./.skilld/releases/@clack/prompts@1.0.0.md) ✅ Guard against empty `options` arrays in `select`/`multiselect` — passing `[]` throws `TypeError: Cannot read properties of undefined` [source](./.skilld/issues/issue-144.md) ✅ Vim keybindings (`h/j/k/l`) and `Escape` → cancel are enabled by default since v0.9.0 — `updateSettings` cannot disable defaults, only add aliases [source](./.skilld/releases/@clack/prompts@0.9.0.md)
