Ratatui
Ratatui is a Rust framework and cross-platform terminal renderer used to build rich terminal user interfaces. It functions as a toolkit for creating interactive command-line displays, dashboards, and data visualizations.
The library employs an immediate mode rendering approach, where the interface is redrawn every frame based on the current application state. It uses a widget-based layout system to compose complex text-based interfaces.
The framework includes a rectangle-based layout engine and a backend-agnostic drawing system to decouple UI logic from specific terminal emulators. It further utilizes double-buffered output and state diffing to manage how characters are written to the screen.
Features
- Terminal User Interfaces - Provides a comprehensive framework for building rich, interactive, text-based user interfaces within a terminal environment.
- Terminal User Interface Frameworks - Offers a high-performance Rust toolkit for developing stateful, widget-based terminal user interfaces.
- Component Composition Primitives - Builds interfaces by nesting reusable widget components that implement a common rendering trait.
- Rectangle-Based Layouts - Provides a coordinate-based layout engine that manages screen areas using rectangles and constraints for widget positioning.
- Immediate-Mode Rendering - Employs a rendering paradigm that rebuilds the entire user interface from scratch on every frame.
- Immediate Mode UI Frameworks - Provides a rendering architecture where the entire interface is redrawn every frame based on application state.
- Terminal-Agnostic Renderers - Implements a backend-agnostic rendering engine that ensures consistent visual output across different terminal emulators.
- Backend-Agnostic Rendering Pipelines - Implements a rendering pipeline that abstracts terminal-specific output to ensure consistent layouts across different emulators.
- Double Buffering - Utilizes an off-screen memory buffer to prepare entire frames before committing them to the terminal display.
- State Diffing - Optimizes terminal updates by calculating the difference between the current and previous frames to reduce flicker and bandwidth.
- Terminal-Based Dashboards - Provides the necessary primitives and tools to build interactive, data-driven dashboards rendered in the terminal.
- Terminal Data Visualizations - Facilitates the creation of data-rich terminal displays and system state visualizations.
- Terminal Interface Design - Provides a structured system for implementing intuitive and accessible user interfaces for Rust-based terminal tools.
- TUI Libraries - Rust crate for terminal UIs.
