Mkdocs plugin loggers don't use `extra` kwarg formatting messages about mkdocs HOT 7 CLOSED

Using arguments instead of f-strings might still be valid, but last I checked it's not really viable to solve. Let me look again

from mkdocs.

I think this is the relevant documentation. Looking
https://docs.python.org/3/howto/logging-cookbook.html#formatting-styles

from mkdocs.

Yes so there are some super complicated solutions to make other formatting styles work, but this part is unchangeable about the log methods:

• They accept only positional arguments. extra is for something else
• They are hardcoded to use %s formatting.

So these two are pretty much the only reasonable options:

log.info("see %s", stuff)
log.info(f"see {stuff}")

I settled on one of them. Yes it has some performance disadvantages but big advantages in development.

Expected behaviour

Expected behavior for which piece of code?

& I think you're confusing something about the extra parameter. Have you tried using it outside of mkdocs? I'm pretty sure it won't work like that either

Oops, is tightly binded to the formatting scheme, right? Sorry for the noise, closing this...

from mkdocs.

extra is for parameters that might be appropriate for every log message. The example shows user_id - it's a good example, because for a website a user id may indeed be present in almost every log. Then the logging configuration can choose to either print the user id somehow at the beginning in every message, or not print it.

Thanks for the detailed explanation! 👍🏼
