Grab Framework Project

Status of Project

I myself have not used Grab for many years. I am not sure it is being used by anybody at present time. Nonetheless I decided to refactor the project, just for fun. I have annotated whole code base with mypy type hints (in strict mode). Also the whole code base complies to pylint and flake8 requirements. There are few exceptions: very large methods and classes with too many local atributes and variables. I will refactor them eventually.

The current and the only network backend is urllib3.

I have refactored a few components into external packages: proxylist, procstat, selection, unicodec, user_agent

Feel free to give feedback in Telegram groups: @grablab and @grablab_ru

Things to be done next

• Refactor source code to remove all pylint disable comments like:
  • too-many-instance-attributes
  • too-many-arguments
  • too-many-locals
  • too-many-public-methods
• Make 100% test coverage, it is about 95% now
• Release new version to pypi
• Refactor more components into external packages
• More abstract interfaces
• More data structures and types
• Decouple connections between internal components
