Development

This project is managed using Poetry, a fantastic Python packaging and dependency manager. Install the latest version of Poetry before continuing. Development currently requires Python 3.7+.

Set up

Starting from Zero? Not sure where to begin? Here's steps on setting up this Python project using Poetry. Note that Poetry installation instructions should be followed from the Poetry Docs: https://python-poetry.org/docs/#installation

1. While optional, It's recommended to configure Poetry to install Virtual environments within project folders:

   poetry config virtualenvs.in-project true
   

   This makes it easier for Visual Studio Code to detect the Virtual Environment, as well as other IDEs and systems. I've also had issues with Poetry creating duplicate Virtual environments in the default folder for an unknown reason which quickly filled up my System storage.
2. Clone the Repository:

   git clone https://github.com/devine-dl/pywidevine
   cd pywidevine
   

3. Install the Project with Poetry:

   poetry install
   

   This creates a Virtual environment and then installs all project dependencies and executables into the Virtual environment. Your System Python environment is not affected at all.
4. Now activate the Virtual environment:

   poetry shell
   

   Note:
   • You can alternatively just prefix poetry run to any command you wish to run under the Virtual environment.
   • I recommend entering the Virtual environment and all further instructions will have assumed you did.
   • JetBrains PyCharm has integrated support for Poetry and automatically enters Poetry Virtual environments, assuming the Python Interpreter on the bottom right is set up correctly.
   • For more information, see: https://python-poetry.org/docs/basic-usage/#using-your-virtual-environment
5. Install Pre-commit tooling to ensure safe and quality commits:

   pre-commit install
   

Building Source and Wheel distributions

poetry build

You can optionally specify -f to build sdist or wheel only. Built files can be found in the /dist directory.
