## What it is
A pure Go implementation of a GNU-Readline-style library providing line editing for interactive command-line programs. It supports keyboard shortcuts, history persistence, tab completion, and custom prompts across platforms.

## Use cases
- add readline-style line editing to a Go CLI
- implement tab completion in an interactive shell written in Go
- persist command history in a REPL
- build an interactive prompt with keyboard shortcuts
- replace cgo readline dependency with pure Go

## When to choose
- you need readline-like input editing in a Go program without cgo
- you want cross-platform line editing, history, and completion out of the box

## When to avoid
- you need a full-featured shell framework rather than a line-editing library
- your project is not written in Go

## Facets
- artifact type: library
- maturity: stable
- function: cli, developer-tools, terminal-ui
- domain: developer-tools
- platform: go, cross-platform, cli
- tags: readline, line-editing, interactive-terminal, history, tab-completion, command-line
