Hi,
I have been trying to use Pylint with some Django and Google App
Engine projects. The problem I have is that the Django and Google
modules are always in the PYTHONPATH, but are through code when run
using a manage.py or other script. I would rather not change my
enviroment to suit Pylint, so I created an option for Pylint called
ignored-modules which is a csv list of top level modules to not
attempt to import. For example, in my .pylintrc, I have the following
line:
ignored-modules=django,google
Then any "from django.core import foo" and "from google.api import
bar" will be skipped. My patch just includes the code to do this. I
don't have any tests or docs, because I am not sure how to test this
or where to put the docs for this? If this is something that looks
worthwhile to be added to Pylint, I would be happy to add tests and
docs with some guidance.
Thanks,
John
