Another way to set defaults

[RomanKornev]

There needs to be another way to set defaults.
Environmental variables do not work for everything on Windows.
For example:
If I do not want any color for INFO level, I cannot set environment variable LOGURU_INFO_COLOR="" because then it's disabled on Windows.
I cannot do:

_defaults.LOGURU_INFO_COLOR = ""

Since logger is already initialized.
Instead, I have to do extremely hacky stuff like:

from loguru import _defaults, logger
from loguru._logger import Level

logger.info('bold')
logger._levels['INFO'] = Level(_defaults.LOGURU_INFO_NO, "", _defaults.LOGURU_INFO_ICON)
logger.info('not bold')

Since Level is a namedtuple, I cannot even modify it in-place

Perhaps a config file or an .ini file as well would be better.

Oh, that's an edge case I did not think about, thanks for reporting it!

I can see some ways to fix it without hacking inside Loguru internals.

Simply set the environment variable programmatically using os.environ before importing loguru:

import os
os.environ["LOGURU_INFO_COLOR"] = ""
from loguru import logger

But if you want to modify a Loguru default level from your script, better use the .level() method which also acts as a setter:

logger.level("INFO", color="")

This can also be done with .configure():

logger.configure(levels=[{"name": "INFO", "color": ""}])

---

However, this would mean that you have to repeat this inside all of your scripts. That is not very convenient at all. This is why environment variables are useful: set it once, and you're done.

Therefore, a workaround has to be found. I guess that if the string is just a space like setx LOGURU_INFO_COLOR=" " I could interpret that as if it was an empty string, and hence don't colorize anything.

[RomanKornev]

setx LOGURU_INFO_COLOR " " as an empty string

I like that because currently it just inserts a space and breaks all formatting.

The recently published 0.2.2 version should allow you to use an empty string for default color by setting a "spaces only" environment variable.

Don't hesitate to open a new issue if you encounter other troubles. 😉

Thanks for the update @Delgan! Works without issues.
