🌸 Chibi

Tiny, lightweight, and type-safe managed Windows library for lifecycle management and window creation

---

⚡ Features

• 💨 Extremly fast and lightweight
  • Made with a single responsibility, spawn a window and manage its lifecycle. From calling Run() to the window being displayed takes on average 170ms
• ✅ Type safe:
  • Fully abstracts away raw User32 P/Invoke calls into type-safe C# abstractions.
• 🎫 Easy event lifecycle:
  • Zero-allocation event system. Every underlying Windows message (WM_*) maps neatly to a dedicated EventDispatcher.
• 🛠️ Developer Comforts
  • Has a safe cross-thread scheduling, low-memory handling indicators via WM_COMPACTING, system theme detection, native taskbar flashing api and a clipboard api.
• 🚫 No AI Slop
  • Purely written by passionete single-brain-celled autistic individual

🚀 Quick Start

Getting a window up and running requires minimal boilerplate! Here's how to initialize ChibiWindow and hook into events

// Create window class
var window = new ChibiWindow
{
    Title = "Hello! 🌸"
};

// Hook into the easy event ecosystem
window.OnWindowCreated.Subscribe(ev =>
{
    Console.WriteLine($"Window successfully spawned with handle: {ev.Handle}");
});

window.OnKeyDown.Subscribe(ev =>
{
    Console.WriteLine($"Key Pressed: {ev.Key}");
    if (ev.Key == User32.VK.VK_ESCAPE)
    {
        window.Dispose();
    }
});

window.OnMouseMove.Subscribe(ev =>
{
    Console.WriteLine($"Mouse Moved: {ev.Now.X}, {ev.Now.Y}");
});

// Bind your custom loop frame logic
window.OnFrame = () =>
{
    // Your rendering logic here!
    // If left null, Chibi automatically optimizes CPU cycles via MsgWaitForMultipleObjectsEx
    // If you are making more complex program or a game, I recommend not using this and using your own render loop/thread instead
};

// Run the window (this blocks the execution thread)
window.Run(1280, 720, WindowFlags.Resizable | WindowFlags.HighPixelDensity);
