[BUG] SyntaxError: f-string: expecting '}'

[Tiptop4792]

Just made a fresh install on Ubuntu 22.04. - Any idea what causes this?

Describe Constant syntax error, even when running waybackup -h

Terminal output

waybackup -h
Traceback (most recent call last):

Any idea what causes this? Many thanks!

i think it is because of the double-quote inside the double-quote. which python version do you have? i do not get this bug.

[Tiptop4792]

I'm on Python 3.10.12

Thanks for looking into this!

[bitdruid]

you can try if 2.0.1 resolves this. just install via pip and let me know :)

[bitdruid]

you sure you are on 2.0.1 ? 2.0.1 is not on main - only dev

vb.write(message=f"-----> {"in CDX file".ljust(18)}: {sc.CDX_TOTAL:,}")

changed to

vb.write(message=f"-----> {'in CDX file'.ljust(18)}: {sc.CDX_TOTAL:,}")

in 2.0.1

update:

so i tested (now 2.0.2) on ubuntu 24.04 and manjaro 24.1.1 without these errors raising. should be fixed

For me, That solved the bug in those two past versions.
