This repository contains a boilerplate Ruby CLI class that can be used to implement a basic zero-dependency CLI for other Ruby libraries.

• Zero-dependencies, making it ideal for adding a CLI to small libraries.
• Correctly handles Ctrl^C and broken pipe exceptions.
• Catches any other exceptions and prints a bug report.
• Defines the CLI as a class, making it easy to test.
• Comes with boilerplate RSpec tests.

If you want to build a CLI for a large Ruby app or framework, and don't mind adding an extra dependency for a CLI library/framework, I recommend the following Ruby CLI libraries:

• cmdparse
• dry-cli
• command_kit
