Ratatui Ruby TUI Development

About

This skill provides expert guidance for developing high-performance terminal user interfaces (TUIs) in Ruby by leveraging the Ratatui library. It covers the entire development lifecycle, from managed terminal setup and teardown to complex layout design using constraints and styling. Developers can use it to build either full-screen applications or 'inline' rich CLI components, utilizing a comprehensive widget library, event-driven pattern matching for input, and the Tea Model-View-Update architecture for robust state management.

Key Features

• Managed terminal lifecycle handling with automatic screen setup and teardown
• Dual operating modes for full-screen TUIs or inline CLI rich moments
• Extensive widget catalog including Tables, Lists, Gauges, and Charts
• 13 GitHub stars
• Advanced testing suite with snapshot comparisons and event injection
• Flexible layout system using percentage, length, and fill constraints

Use Cases

• Enhancing standard CLI scripts with rich inline progress indicators and spinners
• Developing interactive terminal dashboards for real-time system monitoring
• Building complex, state-managed terminal applications using the Tea (MVU) pattern
