V(ersioned) (P)ython

This lightweight utility for versioning Python captures the contents of any file after you run it. It works with args. To use:

1. Clone this repo
2. Run pip install . in the root directory of the repo
3. Any time you run python ..., run vython ... instead.

Example: run vython helloworld.py in the root directory to get the output:

> vython helloworld.py
hello world

Versions are saved as json files such as:

{
    "timestamp": "2022-04-12 16:13:34.875372", 
    "filename": "/Users/shreyashankar/Documents/projects/vpython/helloworld.py", 
    "command": "/Users/shreyashankar/miniforge3/envs/hawk/bin/python3.9 helloworld.py", 
    "contents": "print(\"hello world\")\n"
}

The default save directory is Path.home()/.vython. To override it, set the VYTHON_SAVE_DIR environment variable.
