Hack CLI Library
================

[](#hack-cli-library)

[![Continuous Integration](https://github.com/hhvm/hh-clilib/actions/workflows/build-and-test.yml/badge.svg)](https://github.com/hhvm/hh-clilib/actions/workflows/build-and-test.yml)

This library provides basic command-line handling, including:

- parsing of `ARGV`
- interactive TTY detection
- color TTY detection

It aims for as much code as possible to be in strict mode.
