Switching logging to loguru

[bastigw]

Hi Jia,

I was thinking of changing the logging system to use loguru. Loguru makes it very convenient to get nice logs and change log levels / output / format etc.

It should be fairly easy to implement, requiring only the following change to each file:

### Remove
from ..libs.logger import get_logger
logger = get_logger(__name__)
### Add
from loguru import logger

I am happy to create a pull request for this.

Hi Basti,

Thanks a lot for PR #10 – I've already merged and closed it!

I'm not familiar with loguru myself -- it sounds like a great idea. I welcome any PR you'd like to contribute. I'll test and merge it when I have time.

Merry Christmas!

Regards,
Jia

Hi Jia,

I have included loguru in my development fork and it works as expected. All tests pass too.
The branch I was basing the feature branch on includes some of the changes of the latest pull request I submitted. Therefore, I think it would make sense to only open the pull request once this is merged so that there are no duplicate changes, if that makes sense.

Hi Basti,

Thank you so much for your PR! Yes, it's a good idea to create the PRs one by one. I've just merged your latest PR into the dev branch today (sorry for my delay!).

Coincidentally, Pandas 3.0 was released via PyPI today (Jan 21, 2026, https://pandas.pydata.org/docs/dev/whatsnew/v3.0.0.html), and it introduced some breaking API changes for Python 3.11+. This caused the notebook tests in GitHub Actions to fail right after I merged your code (https://github.com/HawkMRS/pyAMARES/actions/runs/21225120715). I've made an additional commit to the dev branch on top of your PR, trying to make the code compatible with both Pandas 3.0 and earlier versions. I'm not sure if we fully support Pandas 3.0 (which is a major update) while avoiding new bugs for older versions like Pandas 2.x, but at least the GitHub Actions are now passing again for Python 3.8-3.14.

Since your previous PR is now merged, please feel free to open the loguru PR whenever you're ready! I'm excited to see how loguru improves our logging system.

Thanks again for your continued contributions!

Best regards,
Jia

Hi Jia,

Just opened a PR for loguru. This is based on the latest changes in the dev branch, so there shouldn't be any offsets in the history.
Let me know what you think.
