MinUI 🌒

MinUI is a lightweight terminal UI framework for building games and applications in Rust. It's designed to be simple to use while providing the essential tools you need for terminal-based interfaces.

Why MinUI?

I wanted to build terminal games in Rust, but I found existing libraries either too complex or missing game-specific features. MinUI strikes a balance between simplicity and functionality - it's easy to learn but powerful enough for both traditional TUIs and real-time games.

Features

  • 🚀 Fast: Performance-focused with game development in mind
  • 🎮 Game-friendly: Supports both event-driven apps and fixed-rate game loops
  • 🎯 Simple: Clean, intuitive API that gets out of your way
  • ⌨️ Input handling: Keyboard and mouse events
  • 🎨 Full color support: RGB, ANSI, and named colors
  • 🧰 Safe: Proper error handling and automatic cleanup

Current Status

MinUI is actively developed with these features available:

  • Full color support
  • Simple and customizable widget system
    • Container widget
    • Label widget
    • Text block widget
    • Panel widget
    • Table widget
    • Input widget
    • Predefined common widget layouts
  • Robust error handling
  • Buffered drawing for smooth and efficient updates
  • Built-in game/app loop utilities
  • Simplified character/sprite and map management utilities
  • Easy character/sprite movement support with common Unicode characters built-in
  • Cell management with collision detection options
  • Support for various input methods (customizable key binds with crokey, mouse support, etc.)

Getting Started

Add MinUI to your Cargo.toml:

[dependencies]
minui = "0.2.1"

Basic Example

use minui::prelude::*;

fn main() -> minui::Result<()> {
    let mut app = App::new(())?;

    app.run(
        |_state, event| {
            // Return false to exit
            !matches!(event, Event::Character('q'))
        },
        |_state, window| {
            // Draw your UI here
            let label = Label::new("Press 'q' to quit").with_alignment(Alignment::Center);
            label.draw(window)?;
            Ok(())
        }
    )?;

    Ok(())
}

Run the examples: cargo run --example basic_usage

Perfect for Games and TUIs

Games: MinUI handles the timing, input, and rendering so you can focus on game logic. It supports both turn-based and real-time games with smooth frame rates.

TUI Apps: The widget system makes it easy to build traditional terminal interfaces with HTML-like div containers, as well as panels, forms, layouts, and more.

What makes MinUI different:

  • Minimal learning curve so you can start coding immediately
  • Game-focused features like fixed tick rates and smooth input
  • Lightweight with few dependencies
  • Cross-platform (Windows, macOS, Linux)
