pip freeze for pyproject.toml

Install something with a requirements.txt? Have stuff you've installed with pip, but haven't saved the dependencies yet?

Need it to be in a versioned pyproject.toml instead?

Well, you're in luck, sort of.

This cli does the bare minimum in locking your packages and versions into starter pyproject.toml similar to pip freeze but for pyproject.toml

install

pip install pyproject-freeze==0.1.0

Usage

pyenv local 3.12.6
python -m venv venv_3126
source venv_3126/bin/activate
pip install tomlkit

# now we "freeze" into a pyproject.toml
pypfreeze
