R3BL TUI is a Rust workspace for building modern command-line and text user interface applications.
Its main r3bl_tui crate provides a fully asynchronous framework spanning full-screen TUIs, partial TUIs, interactive selection prompts, REPLs, and terminal multiplexing.
The framework uses an immediate mode reactive architecture with a clean separation between rendering and state mutation. It brings concepts inspired by web and desktop development to terminal applications, including responsive layouts, declarative styling, and reusable components.
This is free and open source software.
Key Features
- Fully asynchronous architecture with a non-blocking main event loop.
- Build full-screen, partial, and hybrid TUI applications.
- Immediate mode reactive UI with unidirectional data flow.
- Responsive FlexBox layout engine.
- CSS-like styling and JSX-inspired declarative layouts.
- Async readline support for interactive shells and REPLs.
- Interactive selection API for choice-based user interfaces.
- Terminal multiplexer support using pseudoterminals.
- Reusable components including editors and dialogs.
- Markdown parsing with syntax highlighting.
- Gradient and comprehensive terminal colour support.
- Double-buffered compositor with diff-based rendering.
- Designed to work across Linux, macOS, and Windows.
