Can `loguru` conditionally display the extra field if the data is non-empty only?

My template contains | {extra} at the end. Is it possible to only print that part of any extra arguments are present? Right now all my logging lines without extra data end in | {}.

You need to use a dynamic format function:

def formatter(record):
    if record["extra"]:
        return "{time} {message} | {extra}\n{exception}"
    else:
        return "{time} {message}\n{exception}"

Thank you!
