splogging

Ever had that feeling like quickly wanting to activate logging for your script, but were slightly overwhelmed by the plethora of settings and commands, so you are now running with no logging at all?

Enter splogging!

Just run pip install, do a from ... import ... and finally initialise your logger with my_logger=logger.setup_logging().

That's all it takes to get your logging up and running.

Of course, you can customise your new logger with the parameters shown below.

Happy logging!

Install splogging

$ pip install splogging 

Use splogging

Create one logger

Use this "one logger" setup, if you want same config for output to screen (terminal) and log file.

from splogging import logger

if __name__ == "__main__":
    logger = logger.setup_logging(
        filename="my.log", when="W0", file_level="info", console_level="info",
    )

    logger.info("Log message to console and in file.")

Create multiple loggers

Use this "multiple logger" setup, if you want to configure (and use) multiple loggers separately.

Specify a unique name for each logger.

from splogging import logger

if __name__ == "__main__":
    logger_file = logger.setup_logging(
        name="A",
        filename="steven.log",
        when="W0",
        file_level="info",
        console_level=None,
    )
    logger_console = logger.setup_logging(
        name="B",
        filename="steven.log",
        when="W0",
        file_level=None,
        console_level="info",
    )

    logger_file.warning("In File!")
    logger_console.warning("In console!!!")
