Sharing Environment Variables Between Recipes
Each line of each recipe is executed by a fresh shell, so it is not possible to share environment variables between recipes.
Using Python Virtual Environments
Some tools, like Python’s venv,
require loading environment variables in order to work, making them challenging
to use with just. As a workaround, you can execute the virtual environment
binaries directly:
venv:
[ -d foo ] || python3 -m venv foo
run: venv
./foo/bin/python3 main.py
