Ruby CLI Development

Build Ruby CLI tools using Thor for commands and Zeitwerk for autoloading.

Quick Navigation

• Starting a new CLI gem from scratch? See references/bootstrap.md
• Adding commands or subcommands? See references/patterns.md
• Thor syntax reference? See references/patterns.md
• Rich terminal UI with Gum? See references/gum.md

Core Principles

• Use compact class declarations: class GemName::Cli::Main < GemName::Cli::Base
• Use extend self instead of module_function for utility modules
• Keep the Base class lean - add helpers as patterns emerge
