README

This is an experimental implementation of python 3.11 interpreter, written in golang.

How to use:

echo 'print("Hello, world")' > hello_world.py
python python_to_instructions.py hello_world.py output.json && go run main.go

Motivation

1. I want to make smaller (in terms of LOC) and easily maintainable version of CPython. Golang gc, default collections, reflection and so on - should dramatically reduce python codebase.
2. I want to make python version without GIL, with golang concurency. Golang-related features (like goroutines and channels) will be added in additional module.
3. It feels good working on it.

What's done already?

• A partial implementation of builtin types:

  • list
  • dict
  • tuple
  • str
  • int
  • float
  • function
  • bool
  • NoneType

• 17/165 opcodes

Roadmap

• Clean-up non-exception related TODO's.
• Add exceptions
• cleanup exception-related TODO's

* This is not a complete roadmap, only a bunch of goals on a week or two to give readers a better understanding about this project.
