First, install dev dependencies:
poetry install --with dev
To run all tests, you'll need to install multiple Python interpreters. On a
modern Ubuntu distribution you can use add-apt-repository
ppa:deadsnakes/ppa.
Depending on if you can install the wheels directly for your OS, you may need the libraries to build PIL, too. Here's the Ubuntu commands:
sudo apt-get install build-essential python-dev python3-dev sudo apt-get install libjpeg8-dev zlib1g-dev
Here's the OSX Homebrew command:
brew install libjpeg libtiff little-cms2 openjpeg webp
Finally, just run tox:
poetry run tox # or poetry shell tox
If you want, you can test against a specific version like this: tox -e py312-pil
Run ruff to check formatting:
ruff format qrcode
