Interfacing with Typer and Rich

[ChristianMichelsen]

Hi and once again thanks for a great logger package!

I have currently implemented a CLI package with Typer which recently introduced compatibility with Rich.
This provides some really pretty stack traces in the case of errors.

Below a MWE:

import typer
from logger_tt import logger, setup_logging


with_logging = False


def main(name: str):

    if with_logging:
        setup_logging()

    print(f"Hello {name}")
    print("Hello" + 3)


if __name__ == "__main__":
    typer.run(main)

and run it with python typer_test.py ExampleName. This produces the following result in my terminal:

Compare this to the result when using logger_tt (i.e. setting with_logging = True above):

How does one make Typer and logger_ttto play together nicely?

I completely understand if you feel that this isn't a issue with logger_tt but rather Typer, however, maybe I am just overlooking a simple setting that'll make it work.

Hi @ChristianMichelsen

Can you clarify more on "play together nicely"?
You want to make the traceback output to shown as a window with colored text in the terminal as rich's output ?

If so, the easiest way is to pass the traceback to rich.traceback.Traceback, then print it with rich.console.Console.print.
You can get the logic from typer/main.py.
For the traceback passing and printing, you can modify the handle_exception function

Have a good day,

Hi @Dragon2fly and thanks for your quick response!

Yeah, I have the following 2 issues:

1. How to remove (most of) the irrelevant traceback from Typer, such that only the last few lines, the actual error, are included in the logs (and on screen)
2. How to format the errors on screen in a nice way, if not using Rich, then similar to Rich.

I'll tak a look at your suggestions in the meanwhile. Thanks a lot!

Not familiar with typer, but I'm using logger_tt with rich.
You just need to remove the default StreamHandler and add a rich.logging.RichHandler either by editing the config file or by adding a few lines of startup codes, and rich will take care of all the color rendering.

Hey @ZeroRin and thanks a lot for your suggestion - it worked!
Now everything plays nicely together and also looks very slick. Thanks a lot!
