Disable colors when logging to a file and running outside Docker

Logging to a file when running outside Docker

I found this issue when experimenting with logging to a file using the configuration from documentation:

When logging to a file outside Docker (running the app directly), escape color sequences are present. I tried to explicitly use the optionuse_colors=False here:

asab/asab/log.py

Lines 56 to 60 in 7c76f10

	self.FileHandler.setFormatter(StructuredDataFormatter(
	fmt=Config["logging:file"]["format"],
	datefmt=Config["logging:file"]["datefmt"],
	sd_id=Config["logging"]["sd_id"],
	))

...but that didn't help.

---

The config:

[logging:file]
path=./output.log
format=%(asctime)s %(levelname)s %(name)s %(struct_data)s%(message)s,
datefmt=%d-%b-%Y %H:%M:%S.%f
backup_count=3
rotate_every=1d

The app:

#!/usr/bin/env python3
import logging
import asab

L = logging.getLogger(__name__)


class MyApplication(asab.Application):
	async def main(self):
		a, b = 24, 0
		try:
			print(a / b)
		except ZeroDivisionError:
			L.error("Division by zero.", struct_data={"a": a, "b": b})

		self.stop()


if __name__ == "__main__":
	app = MyApplication()
	app.run()

Output:

27-Jul-2023 17:18:39.572756 �[1;36mNOTICE�[0m asab.application is ready.,
27-Jul-2023 17:18:39.572942 �[1;31mERROR�[0m __main__ [sd a="24" b="0"] Division by zero.,

Can you split this into two issues?

[ateska]

Is this solved by #361 ?

If yes, then close this one, please. @mejroslav

Sorry for the late response, @ateska. Unfortunately, it is not. The color escape sequence is still there.
