Original GitHub issue: https://github.com/mthenw/frontail/issues/231

When using the following python script and commands, no updates are printed (no progress dots)

import sys
from time import sleep

sys.stdout.write("starting\n")
while True:
    sys.stdout.write(".")
    sleep(3)

python -u progress.py > test.log

frontail test.log

Is there a way to get these updates to match the tail -F command which does show and update the progress dots line?

yeah, the thing is that this script doesn't produce new lines. Frontal doesn't react to those changes.

Thank you for your response. Is this on purpose? Would there be a way or option to enable this to get closer to the real tail behaviour?

It's not on purpose. Assuming that there is always a new line simplifies the implementation. I've never considered changing that behaviour as it would require lots of changes (I guess).
