Developper guideline

Add a dependency

Write the dependency in setup.py. As it's the distribution standard for pypi, I prefer to keep setup.py as single source of truth.

I encourage avoiding using instruction as pipenv install requests to register a new library. You would have to write your dependency in both setup.py and Pipfile.

Install development environment

Use make to instanciate a python virtual environment in ./venv and install the python dependencies.

make install_requirements_dev

Update release dependencies

Use make to instanciate a python virtual environment in ./venv and freeze dependencies version on requirement.txt.

make update_requirements

Activate the python environment

When you setup the requirements, a venv directory on python 3 is created. To activate the venv, you have to execute :

make venv
source venv/bin/activate

Run the linter and the unit tests

Before commit or send a pull request, you have to execute pylint to check the syntax of your code and run the unit tests to validate the behavior.

make lint
make tests
