Change defaults _programmatically_

[stdedos]

Hello there,

I have read the documentation for personalization

loguru/README.md

Lines 343 to 349 in 764cd30

	### Personalizable defaults through environment variables
	Don't like the default logger formatting? Would prefer another `DEBUG` color? [No problem](https://loguru.readthedocs.io/en/stable/api/logger.html#env):
	```bash
	# Linux / OSX
	export LOGURU_FORMAT="{time} | <lvl>{message}</lvl>"

but ... can I do this in-code instead? 😅

Without doing too much work / copying too much code.

I will bite the bullet if because of async operations, some messages manage to bypass my setting of the LOGURU_DEBUG_COLOR=<white>.

Hi @stdedos.

These environment variables are primarily intended to your personal development environment. You setup them once, and then you can jump into each new project with a logger that is already configured to your preferences.

If you need to modify them at the application level, I strongly recommend that you explicitly configure the logger using the corresponding API methods. You should define the handlers using logger.add() or logger.configure(). You can also update the level colors using, for example, logger.level("DEBUG", color="<white>").

I don't "need" ... but that personal preference is a bit more than just personal.

So it'd make sense to just configure it and be done with it 🙏

Thank you 😊 It felt so weird to have the option to personally configure them but "not obviously mentioned" that you can do that programmatically too

And I remember from a couple of issues/docs that the way to change the default handler was to remove the existing one - I basically didn't want to start redefining everything
