level with fix width

[mischlrebl]

thank you for the very useful tool.

is it possible to write the level with a fix width of chars into a file? appreviated with 4, or padded to 7, ....
format="{time:YYYY-MM-DD HH:mm:ss.SSS} | {level} | {message}"

Hi @mischlrebl.

This is indeed possible. You can define the abbreviated level name, and use it in a custom format.

import sys
from loguru import logger


def formatter(record):
    record["extra"]["short_level_name"] = record["level"].name[:4]
    return "{time:YYYY-MM-DD HH:mm:ss.SSS} | {extra[short_level_name]} | {message}\n{exception}"


logger.remove()
logger.add(sys.stderr, format=formatter)


logger.warning("Test")

you can use Python's format style to do padding
