error loading matlab a2l generated file

[MCO-SOCOMEC]

Hi Cristoph,
I'm still Michele here :). Now that pyxcp works fine with matlab executables I would like to parse also the generated a2l file. I tried your library but I got an error at db write.
Looking online it seems sometimes a problem of version of python .. can you give me any hint?
Thank you very much for the support
Michele

TypeError: zip() takes no keyword arguments

I forgot to upload the file: I renamed it from .a2l to .txt to overcome the file extension limitations of github.
thanks

Hi Michele,

Yes, it was indeed a version issue, but the root cause was the ruff checker,
no strict keyword argument to zip builtin function is considered an error...

B905 `zip()` without an explicit `strict=` parameter

This is fixed now, have fun!

[MCO-SOCOMEC]

Thank you Christoph,
I updated to 0.14.5 but I still get the very same error. Do I have to do something else?
thanks again
Michele

[christoph2]

0.14.5?
Hmm...
The latest build is 0.14.12

[MCO-SOCOMEC]

Thank you, I have problems installing last version. It seems pip sees up to 0.14.5. I tried to install manually but then I have the same problem with dependencies .. At the end I corrected by hand 0.14.5 as you did and everything is working fine.
Thank you very much for the great support
Michele
