Usage with tqdm

Is there any way of using loguru.logger with tqdm?

I’ve tried many solutions but nothing printed the progress bar of tqdm in one line. In all solutions that I tried, each update of tqdm progress bar was a new line. For example:

  0%|           | 0/100 [00:00<?, ?it/s]
  1%|1         | 1/100 [00:00<00:09,  9.98it/s]
  2%|2         | 2/100 [00:00<00:09,  9.97it/s]
  3%|3         | 3/100 [00:00<00:09,  9.97it/s]

@vmvz Yeah, sorry, this has been changed in v0.4.0 (the .add() method no longer automatically pass extra arguments to sink, because this was prone to error).

Instead, on should use this:

logger.add(lambda msg: tqdm.write(msg, end=""))

I updated the documentation consequently.

Hi.

Did you try to replace the default handler with tqdm.write()? It seems to work fine for displaying the progress bar:

from tqdm import tqdm
from loguru import logger
import time

logger.remove()
logger.add(tqdm.write, end="")

logger.info("Initializing")

for x in tqdm(range(100)):
    logger.info("Iterating #{}", x)
    time.sleep(0.1)
