WARNING: this project is still in a pre-alpha state!

Using this in a production project is inadvisable. Please only do so if you understand the risks.

Usage

Check out our online demo running on WebAssembly.

Goals

  • A clean implementation without compatibility hacks

Quick Documentation

pyEval(code, options?);

code: string: The Python code to run

options:

  • vars?: { [key: string]: any }: Variables passed to the VM that can be accessed in Python with the variable js_vars. Functions do work, and receive the Python kwargs as the this argument.
  • stdout?: "console" | ((out: string) => void) | null: A function to replace the native print function, and it will be console.log when giving undefined or "console", and it will be a dumb function when giving null.
  • stderr?: "console" | ((out: string) => void) | null: A function to replace sys.stderr, and it will be console.error when giving undefined or "console".
