📦 Installation

# Using npm
npm install rad-gui

# Using yarn
yarn add rad-gui
Copy

🚀 Quick Start

JavaScript

import { GUI } from 'rad-gui';
import 'rad-gui/lib/rad-gui.css';

// Create a GUI instance
const gui = new GUI();
const params = { x: 0, y: 0, color: '#ff0000' };

gui.add(params, 'x', 0, 100);
gui.addColor(params, 'color');
Copy

TypeScript

import { GUI, ControlEventData } from 'rad-gui';
import 'rad-gui/lib/rad-gui.css';

interface DemoParams {
  x: number;
  y: number;
  color: string;
  enabled: boolean;
}

const gui = new GUI({ title: 'Controls', width: 300 });
const params: DemoParams = { x: 0, y: 0, color: '#ff0000', enabled: true };

// Full type safety and IntelliSense support
gui.add(params, 'x', 0, 100)
  .onChange((data: ControlEventData<number>) => {
    console.log(`X changed to ${data.value}`);
  });

gui.addColor(params, 'color');
gui.add(params, 'enabled');
Copy

For a complete example, see our TypeScript Example which demonstrates all features with proper typing.

📚 Documentation

RAD-GUI provides comprehensive type definitions and IntelliSense support for TypeScript projects. The library includes:

• Complete type definitions for all controls and options
• Proper event callback typing with structured data
• Generic overloads for type-safe parameter handling
• Interface definitions for configuration objects

📋 API Reference

Creating a GUI

// Basic GUI creation
const gui = new GUI();

// With options
const gui = new GUI({
  title: 'My Controls',
  width: 300,
  autoPlace: false,
  closeFolders: true
});
Copy

Adding Controls

// Auto-detected control types
gui.add(object, 'numberProperty');     // → NumberControl
gui.add(object, 'booleanProperty');    // → ToggleControl  
gui.add(object, 'stringProperty');     // → TextControl
gui.add(object, 'functionProperty');   // → FunctionControl

// Explicit control types
gui.add(object, 'number', 0, 100, 1);           // NumberControl with range
gui.add(object, 'option', ['A', 'B', 'C']);     // OptionControl
gui.addColor(object, 'color');                  // ColorControl
Copy

Event Handling

// Individual control events
gui.add(params, 'value')
  .onChange((data: ControlEventData) => {
    console.log(`${data.property} changed to ${data.value}`);
  })
  .onFinishChange((data: ControlEventData) => {
    console.log('Finished changing:', data);
  });

// Global GUI events  
gui.onChange((data: ControlEventData) => {
  // Called for any control change
});

gui.onOpenClose((gui: GUI) => {
  // Called when folders open/close
});
  doSomething() { 
    console.log('Button clicked!');
  }
};

// Add controls
gui.addColor(params, 'color').name('Color');
gui.add(params, 'x', 0, 100).name('X Position');
gui.add(params, 'y', 0, 100).name('Y Position');
gui.add(params, 'enabled').name('Enabled');
gui.add(params, 'option', ['A', 'B', 'C']).name('Option');
gui.add(params, 'doSomething').name('Run Action');

// Create a folder for grouped controls
const folder = gui.addFolder('Advanced Settings');
folder.add(params, 'x').step(5).name('X (Step 5)');
Copy

🤖 For AI Assistants and Tools

This project includes a .llm.reference.md file specifically designed for AI assistants, agents, and tools to better understand and work with the codebase. This file contains:

• Comprehensive architecture overview
• Key component descriptions
• Usage patterns and code examples
• Core utility functions

AI tools can reference this file to provide more accurate and helpful suggestions when working with rad-gui.

📋 Available Controls

RAD-GUI supports various control types based on the parameter's value and provided options:

Type	Description	Example
Number	Slider or text input for numbers	gui.add(params, 'x', 0, 100)
Boolean	Checkbox for true/false values	gui.add(params, 'visible')
String	Text input field	gui.add(params, 'name')
Function	Button that calls a function	gui.add(params, 'save')
Color	Color picker	gui.addColor(params, 'color')
Options	Dropdown for selecting from options	gui.add(params, 'size', ['S', 'M', 'L'])

🎨 Customization

RAD-GUI is easily styled using CSS variables:

// Create and apply a custom theme
const darkTheme = {
  '--background-color': '#1a1a1a',
  '--text-color': '#e0e0e0',
  '--title-background-color': '#272727',
  '--title-text-color': '#ffffff',
  '--widget-color': '#2c2c2c',
  '--hover-color': '#3c3c3c',
  '--focus-color': '#444444',
  '--number-color': '#2cc9ff',
  '--string-color': '#a2db3c'
};

// Apply theme to a specific GUI instance
Object.entries(darkTheme).forEach(([key, value]) => {
  gui.domElement.style.setProperty(key, value);
});
