# Textual Calculator on Hugging Face Spaces

This Space demonstrates a fully functional calculator application built with [Textual](https://github.com/Textualize/textual) and served through [textual-serve](https://github.com/Textualize/textual-serve) on Hugging Face Spaces.

## What is this?

This Space runs a macOS-inspired calculator application as a Terminal User Interface (TUI) in your web browser. It showcases how sophisticated TUI applications can be deployed as web apps using Textual and Hugging Face Spaces.

## Calculator Features

- 🔢 Full arithmetic operations (addition, subtraction, multiplication, division)
- % Percentage calculations
- ± Sign toggling
- 🖱️ Click buttons with your mouse
- ⌨️ Use your keyboard for input
- 🎨 Beautiful macOS-inspired design
- 🚀 Real-time interaction via WebSockets

## How it works

1. The Docker container runs a textual-serve server on port 7860
2. The server spawns the Textual demo application as a subprocess
3. WebSocket connections handle bidirectional communication
4. Your browser displays the terminal interface

## Want to deploy your own Textual app?
