pySpy

pySpy attempts to re-create the experience of dnSpy, but for Python bytecode.

You can easily view and edit the bytecode, names, and constants. All with a relatively intuitive GUI.

Version support

Currently, the editor doesn't aim for cross-version support. You can only edit the bytecode of the version that you're running the program on. It uses dearpygui for the GUI, which can only run on Python versions 3.7 - 3.10

It uses an internal module to edit the bytecode, which handles all the converting from and to native code objects. It also ensures all jump arguments are up-to-date.

How to use

pip install -r requirements.txt

python3 pyspy

Missing features

There are a lot of opportunities to make this better, for example:

A debugger
Create new code objects
~~Add constants~~ Added
~~Add names~~ Added
Add new instructions
Plugin support

In other words, contributing is appreciated.
