gsubpy

This is an interpreter for subset of Python3 written by golang, which means it will just realize some certain features, some like import, many things will not be implementd. It's intended to be small and simple. (Maybe I will add some features I think cool. At that time, I need give it a new name.)

In a word, gsubpy, a Python interpreter for fun, not big things.

Quickstart

• install

$ go install github.com/realyixuan/gsubpy@latest

with repl:

$ gsubpy
>>> print("Hello world")
Hello world 

or with .py file (there are some examples under demos/):

$ gsubpy a_py_file.py
