@logger.catch to log file?

I had a look through other issues and couldn’t find anything relevant so here goes.

Can I intercept an unhandled exception in my function so that the printed traceback gets also put into my sink file? I tried with both @logger.catch() and @logger.catch(reraise=True), both to no avail.

Exceptions occurring inside a function decorated with @logger.catch should be logged to your sinks.

Basically, logger.catch() is a s simple wrapper around your code which does the following:

try:
    return some_function()
except Exception:
    logger.exception("An error occurred")

You may need to wrap your entire application of you want to catch any exception occurring anywhere, for example (logger.catch() can be used as a context manager too):

if __name__ == "__main__":
    with logger.catch():
        start_my_app()

The stack trace should be written to your file as long as the exception is caught by Loguru, or that you manually log it using logger.exception("Some message") in the except block of exception handling.

@mowarsadsa The test function does not seem decorated with logger.catch() so the raised Exception can’t be captured by Loguru.
