Setup

• This project uses Pipfiles to manage Python dependencies.
  • To install pipenv: instructions
  • For more information on Pipfile and Pipfile.lock usage: documentation
• Run pipenv install in the same directory as the Pipfile whose dependencies you want to install.
  • apk-downloader, gpcrawler, and privacy each contain a Pipfile and Pipfile.lock for their respective dependencies.
  • There are conflicts between the dependencies for the three subdirectories, so it is recommended to use separate environments.
• setup.cfg contains formatting rules for development.
  • To lint code, install pylint and run python -m pylint **/*.py **/**/*.py --rcfile=setup.cfg
