Doesn't catch Python 3.12 f-strings changes
Describe the bug Vermin doesn't catch changes introduced in Python 3.12 to f-strings. Specifically, f-string nesting. See https://docs.python.org/3/whatsnew/3.12.html#pep-701-syntactic-formalization-of-f-strings
To Reproduce
I had the following line in my source:
Paragraph(f'{split_fio_birthdate(visitor['fio'])[0]}', normal_style), (please note single quotes inside f-string as well as enclosing ones).
When I invoked vermin with vermin -v --exclude-regex venv ., it incorrectly marked the file containing that line as !2, 3.9. The actual run attempt on Python 3.11.2 threw the following error: SyntaxError: f-string: unmatched '['.
Expected behavior
The file should be marked as !2, 3.12.
Environment (please complete the following information):
- vermin 1.6.0
- Python 3.12 on the machine I run vermin on (I think with Python 3.11 that line might trigger syntax error)
Hello there. Sorry for the slow reply. I am currently making support for Python 3.13 in Vermin and fixing other issues, too. It is still undecided about the f-strings as I purposefully use the built-in parser of Python such that the project can remain vanilla Python code. The information needed to do the analysis you request is, unfortunately, thrown away by the parser.
