This guide provides best practices and patterns for developing sophisticated, user-friendly command-line interface (CLI) tools in Rust, drawing examples from the sapphire-cli
project.
- Discoverability: Easy to find commands and options (e.g.,
--help
). - Feedback: Keep the user informed about what's happening (e.g., spinners, progress bars, status messages).
- Clarity: Use clear language, consistent terminology, and well-formatted output.
- Robustness: Handle errors gracefully and provide informative error messages.
