Change color of output

[erikpa1]

Hi I'm trying to configure color output for formatting, but I'm loosing this battle, I have no idea what you did with logger, but everything I try works on "clear" logging, but not on logger coming with flask. Can you configure logs like this please ? Like, why python ["INFO"] log is red in console ?

This code works with logging, but not with flask.

class CustomFormatter(logging.Formatter):
    grey = "\x1b[38;20m"
    yellow = "\x1b[33;20m"
    red = "\x1b[31;20m"
    bold_red = "\x1b[31;1m"
    reset = "\x1b[0m"
    format = "%(asctime)s - %(name)s - %(levelname)s - %(message)s (%(filename)s:%(lineno)d)"

    FORMATS = {
        logging.DEBUG: grey + format + reset,
        logging.INFO: grey + format + reset,
        logging.WARNING: yellow + format + reset,
        logging.ERROR: red + format + reset,
        logging.CRITICAL: bold_red + format + reset
    }

    def format(self, record):
        print(record)
        log_fmt = self.FORMATS.get(record.levelno)
        formatter = logging.Formatter(log_fmt)
        return formatter.format(record)

logger = logging.getLogger("tmp")
logger.setLevel(logging.DEBUG)

# create console handler with a higher log level
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

ch.setFormatter(CustomFormatter())

logger.addHandler(ch)

logger.info("Hello")
logger.error("Hello")
logger.debug("Hello")
logger.warning("Hello")
