Use pm2 with loguru

Hello!

I have been very appreciated to use loguru where a friend of mine has showed me and its been what I have been looking for in ages!

I have some issues with it and I wouldn’t say its a bug or so, maybe a new feature or something I might have missed?

What I have done is super simple script such as:

from loguru import logger
logger.info("hello world")

and I tried to run it with something called PM2 which looks like this:

The only issue is that it marks it as a “error” with the red line which shouldn’t. How is when I change it to a normal print:

print("hello world")

So my question is simple as, is it possible to do something similar where logger.info would mark it as a “green” success color in the pm2 while exception/debug could be red?

As I mentioned, its probably maybe not an issue but maybe a cool feature for those who uses pm2 and if there is anything I can help you out, please let me know! 😃

Thanks for the write-up!

Usually I would configure the logger inside an if __name__ == "__main__" block in case the app is used as a library. However, as you call .remove() before .add(), even if the module happens to be re-imported for some reason, it should not be noticeable.

Glad you found a solution. I wish a good day to both of you too. 👍

Was giving advise to @BarryThrill in a side channel, this is what we came up with:

shunt the pm2 sink & logger configuration to a module, that executes the necessary loguru configuration calls on import. this has two major effects:

• this code only ever executes once unless dynamic module reloading hackery is employed
• this code can be re-used by multiple executables under the same project, without special effort.

Specifically we shunted it to the package’s top-level __init__.py, so it executes on startup as a natural result of executing anything under the package via -m.

This does have the unfortunate side effect of working too well, im not sure we can do an entry-point check on __init__.py to prevent the logger reconfiguration if the project is imported by something else; though in this application thats not important (as its not a library).
