Intercepting functions with pdb

python -m pyintercept setup.py setuptools.setup --handler=pyintercept.pdb

This will call pdb before any calls to setuptools.setup

Writing your own interceptor

Let's print the settings file to be used in a Django project.

print_settings.py

def handler(origfn, *args, **kwargs):
    import os
    print(os.environ["DJANGO_SETTINGS_MODULE"])

python -m pyintercept manage.py django.core.management.execute_from_command_line --handler=print_settings.handler
