Overview

This bot listens for messages in Discord. When a message starts with !code, it:

1. Extracts the code snippet from the message.
2. Determines the programming language based on code block syntax or initial tokens.
3. For executable languages (Python, JavaScript, Java, Ruby): runs the code via a sandboxed API (Judge0 CE) and returns the output.
4. For markup languages (HTML/CSS): beautifies and highlights the code before sending it back.

Supported Languages

• Python
• JavaScript
• HTML/CSS
• Java
• Ruby
