m5rcode – The Unofficial Polyglot Programming Language

m5rcode is an experimental polyglot programming language written with a blend of Python, JavaScript, PHP, C#, and C++.
It uses obfuscation and cross-language embedding to allow developers to write multi-language scripts in a single file (.m5r).
The project includes a custom REPL shell (m5rshell) and an interpreter for .m5r files.

✨ Features

• Polyglot Language Core

  • Mix Python, JavaScript, PHP, CSS, C#, and C++ in a single .m5r file.
  • Interpreter extracts, executes, and blends code blocks.
  • Supports obfuscation for added challenge and uniqueness.

• m5rshell – The REPL Shell

  • Interactive REPL for testing code snippets.
  • Commands:
    • new, nano, run, fastfetch, credits, exit, cd
  • Developer-friendly CLI for creating & running .m5r scripts.

• .m5r File Runner (Interpreter)

  • Executes .m5r polyglot files directly.
  • Efficient, multi-language-aware execution engine.
  • Provides fast output even for obfuscated code.

📝 Example

Here’s a hello.m5r script that prints Hello world in all supported languages:

<?py
