Loguru: Multiple arguments

[filantus]

Hi! Can you please tell, it's possible to achieve behavior with loguru.info() like print() function in case of multiple arguments?

For example, with print() i can do: print(1, 'abc', True), but loguru.info() takes only first argument for message.

I can reach desired result if i do:

loguru.info(', '.join([str(a) for a in (1, 'abc', True)]))

But make it every time too exhausting.

Hi @filantus. :slightly_smiling_face:

Logging messages with Loguru is more like using format() than print(). Actually, logger.info("{} {} {}", 1, "abc", True) is roughly equivalent to "{} {} {}".format(1, "abc", True).

Brace-formatting is actually more powerful than print(), that's why this is the preferred way to format message using the logger. :wink:

Thank you for answer.
Yes, i now. And since Python 3.6 i also can use f-strings for this purposes. But then i just want rapid debug something, brace-formatting is overburdening me.

I even can replace logger.info() method using from functools import partialmethod with my own wrapper for desired effect, but then appears new problem - {module} and {function} referrers only to wrapper function, not to real invoke place.

So, i understand what loguru.info() not receive multiple message arguments, and probably not will do in future. But maybe there is another way? It's possible to make wrapper and save original {module} and {function} output?

Maybe that Loguru is not the best tool for "rapid debug", and something more appropriate like icecream should be used instead? :confused:

Anyway, I have another suggestion for the {module} / {function} problem: did you try to use opt() to force the context source to be retrieved from the parent function of you wrapper? Something like that:

def debug(*args):
    logger.opt(depth=1).info(" ".join(map(str, args)))

Yeah, it's seems just what i wanted. Thank you very much!

P.S. I understand what loguru not aimed to rapid debugging, and it's not only one purpose for i using loguru. But in some cases i don't want install excess dependencies, just little more comfort with great tool like loguru. :slightly_smiling_face: Thank you again!

Yeah, no problem, I just wanted to mention the existence of more suitable tools. Yet I'm also happy to know that Loguru is modular enough to offer a solution that suits your needs! :smile:
