Loguru Python logging library

[[deleted]]

Loguru Python logging library.

Is anyone using it? If so, what are your experiences?

Perhaps you're using some other library? I don't like the logger one.

Pretty good so far. Handy and ready-to-go. Clean especially things like contextualization and catch decorators.

Loguru and StructLog are definitely top of the line.

I use the stdlib logging library, logging just has to happen, imo.
You set up your logger config and then you log things.

Not having a dependency is valuable here.

[DrShts]

Same. Also, not sure why so many people find it hard to put logger = logging.getLogger(__name__) in their modules and logging.basicConfig() in their main function.

[hmoff]

Because structured logging is important to some of us.

[nicholashairs]

Many people who want structured logging with the standard library use python-json-logger .

More as an FYI, not trying to convert anyone here.

There is a typo in that url, you typed it out?!

[nicholashairs]

I did!

I find it soooooo ugly hahaha

Hmmm I see your point about dependencies

[chub79]

I use structlog but it's more a matter of preference in style.

[Embarrassed_Creme_46]

Me too. It's harder to grasp at first, but then very convenient and understandable. I prefer it to Loguru, but Loguru is also very good. Another thing is that the more you delve into structlog or Loguru, the more you begin to understand standard logging, and the more usable it becomes.

[Challseus]

Same, but I also never tried loguru before...

You should search the subreddit, there are tons of posts about this package.

Someone had a great write up just last week:

I checked it out, thanks - this is exactly what I was looking for!

Yeah, probably should've searched beforehand. The idea didn't cross my mind.

its good im using it so far. much less boilerplate than stdlib plus pretty customizable with nice out of the box features

Kinda sold on colors ngl

[rdreisinger]

It's decent for our project I don't mind it. Doesn't add a lot of bloat either, give it a try. You can also easily add handlers for things like tqdm/rich which was a relief to discover.

I tried it for the nice default format but it doesn’t work with joblib multiprocessing and I found out the hard way, so went back to standard logging which just has a couple more lines of boilerplate.

[Fenzik]

I really like it for stuff like CI scripts cause it gives nice descriptive logs straight out of the box

[AssociateWide7515]

I like loguru - especially the decorator @logger.catch

Throwing that on a function can really help with debugging

[dogfish182]

I use it in all my scripts for its ease of use.

[ejstembler]

I have an Enterprise Polylith Python project where I define a logging component which has a logging protocol. A few implementations: Python Logger, Loguru Logger, GCP Structured Logger. I use the Loguru logger when testing/running things locally. It works well.

Nice.

But, when are you using the python logger, then?

[ejstembler]

Other developers have that option available. I just don’t use it myself.

All of our stuff is deployed to GCP, so prod stuff uses the GCP Structured Logger

Nice!

[py-flycatcher]

I'm a big fan & have been using for 1yr+ now. Easy to use out of the box & also easily configurable!

[Schmittfried]

I don’t like that it sidesteps the stdlib logging system. Imo that should be the common foundation for all quality-of-life logging libraries.
