AttributeError: 'str' object has no attribute 'search'

[Jacobfaib]

Describe the bug
If you define exclusion_regex in setup.cfg, the string is treated as a regex pattern object leading to:

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

To Reproduce

$ python3 -m pip install -U vermin
$ mkdir repro && cd repro
$ echo -e "[vermin]\nexclusion_regex =\n    'foo/'" > setup.cfg
$ touch foo.py
$ vermin ./foo.py # boom

Expected behavior
No exception

Environment (please complete the following information):

$ vermin --version
1.5.2
$ python3 --version
Python 3.11.6

Thank you for reporting this! I will take a look.

I have fixed the issue now. Thanks again!

Note that at new release will come soon that will include this fix among other things.

Out of curiosity, do you have a rough estimate of when this release will be?

Maybe within a week or so. I should be almost done with the Python 3.12 support.
