rc-tui 0.2.0

High-performance React-inspired TUI library for Python

rc-tui

rc-tui is a high-performance, React-inspired Terminal User Interface (TUI) library for Python. It combines the declarative power of modern web frameworks with a high-performance C++ rendering engine to create fluid, beautiful, and complex terminal applications.

Why rc-tui?

• Declarative & Component-Based: Build your UI with functional components and hooks (useState, useEffect).
• Hybrid Performance: High-frequency render logic and terminal diffing are in C++; layout and logic are in Python.
• Advanced Styling: Web-standard colors (Hex, RGB), pseudo-classes (hover, focus), and rich text attributes.
• Cross-Platform: Fully supports Linux, macOS, and Windows 10+ (Verified via CI/CD).

Key Features (v0.2.0)

• Rich Styling: Hex colors, inheritance, box_shadow, and text_transform.
• Interactive Pseudo-classes: Define hover_style and focus_style for responsive components.
• Full Mouse Support: Real-time motion tracking for hovers and tooltips.
• Flexbox Layout: Powerful layout engine with gap, flex_grow, and percentage dimensions.
• Markdown & Code: Built-in support for Markdown and syntax-highlighted code blocks (via Tree-sitter).

Installation

pip install rc-tui

Quick Start

from rc_tui import App, Component, Box, Text, Button, useState

class Counter(Component):
    def render(self):
        count, set_count = useState(0)
        
        return Box(
            flex_direction="column",
            align_items="center",
            gap=1,
            border="rounded",
            padding=1,
            children=[
                Text(f"Value: {count}", style={'bold': True, 'fg': 'cyan'}),
                Button(
                    "Increment", 
                    on_click=lambda _: set_count(count + 1),
                    style={'hover_style': {'bg': 'green'}}
                )
            ]
        )

if __name__ == "__main__":
