Question

I've been using pylint.config.PYLINTRC in the init-hook of the pylintrc to set up the PYTHONPATH.

init-hook="
      import os, pathlib, pylint, sys
      testDir = pathlib.Path(pylint.config.PYLINTRC).resolve().parent.joinpath("test")
      sys.path.append(os.fspath(testDir))"

In pylint 3 this leads to an error

AttributeError: module 'pylint.config' has no attribute 'PYLINTRC'

This method was much more convenient and portable than setting the PYTHONPATH outside of pylint.
What is the preferred way to do this in pylint 3?
