System Documentation

What problem does it solve?

Develop proper, reliable command-line interfaces by providing structured guidance on argument parsing, subcommands, IO handling, testing, and distribution.

Core Features & Use Cases

  • Guidance on choosing when to use CLI vs TUI vs GUI and selecting appropriate libraries for argument parsing.
  • Patterns for streams (stdout/stderr), exit codes, interactive vs non-interactive modes, configuration, and signal handling.
  • Concrete usage examples such as scaffolding a CLI with subcommands, tests, and a distribution plan.

Quick Start

Start by outlining a small CLI tool that uses a modern parsing library, supports subcommands, handles stdin and stdout, includes basic error handling and tests, and demonstrates distribution.
