This directory contains Python-based clients for PiSCSI as well as common packages that are shared among the clients.
The following paragraphs in this README contain instructions that are shared among all Python apps.
The policy in this project is to support the Python 3 interpreter that comes standard with the current stable, as well as previous stable release of Debian.
At the time of writing they are:
- Python 3.11 in Debian Bookworm
- Python 3.9 in Debian Bullseye
The CI workflow is set up to check code formatting with black,
and linting with flake8. If non-conformant code is found, the CI job
will fail.
Before checking in new code, install the development packages and run these two tools locally.
pip install -r web/requirements-dev.txt
Note that black only works correctly if you run it in the root of the
python/ dir:
cd python
black .
Optionally: It is recommended to run pylint against new code to protect against bugs and keep the code readable and maintainable. The local pylint configuration lives in .pylintrc. In order for pylint to recognize venv libraries, the pylint-venv package is required.
sudo apt install pylint3
sudo pip install pylint-venv
source venv/bin/activate
pylint3 python_source_file.py
Examples:
# check a single file
pylint web/src/web.py
# check the python modules
pylint common/src
pylint web/src
pylint oled/src
