Loguru sucks very badly! I would advise you not to use it. It is like trying to not do like everyone else, but still doing in a terribly wrong way ...

For example the backtrace try to be cooler for display but are awful, and totally not appropriate to pipe in monitoring systems like Sentry.

In the same way, as you can see in the article, that is the only logging library that doesn't accept the standard %-string syntax to use instead its own shitty syntax based on format.
