Jupyter Notebooks don't support Halo

While Halo works perfectly fine in the terminal, I can’t get Halo to work inside a Jupyter notebook. I am running the following code in the first cell of the notebook:

from halo import Halo
from time import sleep
with Halo(text='Loading', spinner='dots'):
    sleep(5)

The program runs through without any errors, but no spinner is shown at all.

I figured out, that if you write something to stdout with sys.stdout prior to calling Halo, then the spinner is shown, but each spinner and corresponding text are shown next to each other, i.e. clearing the current line doesn’t work.

from halo import Halo
import sys
from time import sleep
sys.stdout.write('test\n')
with Halo(text='Loading', spinner='dots'):
    sleep(5)

returns the output

test

Loading⠧ Loading⠇ Loading⠏ Loading⠋ Loading⠙ Loading⠹ Loading⠸ Loading⠼ Loading⠴ 
Loading⠦ Loading⠧ Loading⠇ Loading⠏ Loading⠋ Loading⠙ Loading⠹ Loading⠸ Loading⠼

Is there something wrong on my end, and do you have an idea how to fix that? It would be really nice if Halo worked with Jupyter too. Thanks for your efforts and for sharing this library!

This is fixed in #40 thanks to @JungWinter! This will be made available soon in next release. I need to do few fixes before making a release.

@JungWinter Please send a PR for this. I’ll review the code. 😄 Thank you for working on this!
