Unfortunately hunter doesn't have a custom parser, it just uses python. Therefore you must obey python syntax - you can't give a positional argument after a keyword one. Try
Q(filename_contains='venv'),stdlib=Falseinstead.abitrolly commentedon Jan 17, 2021
Do you mean it uses some kind of Python eval to parse the string as function argument?

Yeeep.

Maybe in the future there will be a fancy parser but it's a big feature.

Strange that Python doesn't ship with some basic parser lib that allows to detect pair braces and stuff.
Parameter parser helper to replace eval of env variable (ionelmc#89)
