Overview

Command-line interface for the duoruby executable.

Commands:

  • help — prints usage information

  • version — prints the gem version

  • serve — starts the HTTP/WebSocket server (accepts --host and --port options)

  • launch — starts the server and opens a native webview window

All commands return an integer exit code. duoruby/server is required lazily by serve to avoid loading Falcon/Async for other commands.

Examples:

Programmatic use (mirrors the exe/duoruby entry point)

exit DuoRuby::CLI.new(ARGV, input: $stdin, output: $stdout).call
