Show HN: Tap – Interactive CLI Prompts for Go (Clack Port)

4 points

9 months ago

I’ve been working on a new Go library called Tap: https://github.com/yarlson/tap. It’s a Go port of the TypeScript library Clack https://clack.cc/, bringing its simple, interactive command-line prompts to Go.

Why: I often found myself rewriting input handling, spinners, and progress bars when building CLI tools. Existing options in Go felt either too barebones or too heavyweight. Tap aims to provide a middle ground: ergonomic, event-driven prompts with minimal dependencies.

What works today:

- Text and password input

- Confirm and single-select menus (generic, type-safe)

- Spinners and progress bars

- Styled intro/outro/cancel messages

- Built-in testing utilities

What’s coming next:

- Multi-select

- Autocomplete

- Grouped prompts and themes

Status: Early stage. APIs may change. Core features are tested but it’s not production-ready yet.

I’d love feedback on API design, missing features, and cross-platform quirks.
