zap-repl 0.2.0

Runs a REPL against a separate interpreter

zap-repl

Lets you run a Python REPL inside another process. No GDB required. Works across versions.

Usage:

# To run, then attach
python -m zap_repl /path/to/python foo.py

# To attach to an already-running interpreter
python -m zap_repl -p <pid>

Python ... on ...
>>> import os
>>> print(os.getpid())
<pid>

You can even have multiple attached concurrently, and they share their vars, as well as share vars with an interactive interpreter if there happens to be one.

Doesn't require planning ahead and loading anything in the target process, just a normal Python 3.8+ interpreter with stdlib.

Version Compat
