Proof of concept for a Python Plugin Framework

POC For a Python Plugin Framework

Warning This is just an experiment. Not te be used in production

Note Current status: Working

This experiment looks at how a plugin framework could work at it's most basic level.

The application will load two custom plugins from the file /tmp/test_plugin/my_plugin.py and /tmp/second_test_plugin/my_second_plugin.py, which in turn implements a base class from our application.

Quick run (assuming the repository is freshly cloned):

python3 -m venv venv
. venv/bin/activate
sh prep.sh
pip3 install build
python3 -m build

In a separate terminal window:

pip3 uninstall plugin-poc -y && pip3 install --user /path/to/python_plugin_poc/dist/plugin_poc-0.0.1.tar.gz
plugin_poc
