## What it is
A Go library providing an interface to Unix pseudo-terminals (PTYs). It lets Go programs start commands like exec.Command attached to a PTY, enabling interactive terminal emulation and shell embedding.

## Use cases
- run a shell command attached to a pseudo-terminal in Go
- embed an interactive bash session in a Go application
- capture output of programs that require a TTY
- build a terminal emulator or SSH-like tool in Go
- resize and manage PTY file descriptors from Go
- test CLI tools that behave differently with a TTY

## When to choose
- you need to run or automate interactive terminal programs from Go
- you're building terminal multiplexers, SSH servers, or test harnesses in Go
- you want a small, stable, widely-adopted Go PTY library

## When to avoid
- you need Windows PTY/conpty support as a first-class feature
- you're not working in Go
- you only need simple non-interactive command execution without a TTY

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, cli, concurrency
- domain: developer-tools, operating-systems
- platform: bsd, go, cross-platform
- tags: pty, pseudo-terminal, tty, terminal, process-execution, unix, command-line, linux, macos
