Description of the new feature, or changes

Add multi-threading support so that spinners can be updated individually without affecting other instances.

Example script:

import random
import time
from concurrent.futures import ThreadPoolExecutor

from halo import Halo


def long_running_task(i):
    with Halo(f"Running {i}", spinner="dots") as sp:
        time.sleep(3 + random.random())
    sp.succeed(f"Success {i}")


with ThreadPoolExecutor(max_workers=4) as pool:
    # Number of tasks is greater than max workers
    pool.map(long_running_task, range(8))

And here is the output

test

@frostming Thanks for mentioning me, and the gif looks great. I won't review as I don't have the expertise but I hope that this, or similar, makes it into halo!

@frostming Thanks for working on this. It looks great!

I'll review this over the weekend. But this does require testing and support for notebook environment.

I added a test to cover the basic scenario of multiple running spinners.

But this does require testing and support for notebook environment.

Notebook should be working fine without any changes because instances are rendered in their own output widget, which I confirmed in a local notebook.

Hi, Any progress on the review?

For some reason on the notebook very often one of the widgets gets overwritten:
halo

and in the console I see a lot of:

Popped wrong message (xxx instead of yyy) - likely the stack was not maintained in kernel.

@manrajgrover is there any reason this PR hasn't been approved? Is this project actively maintained anymore?

Very good change. I also would like several spinners for multiprocessing.

Still not merged? I was looking for exactly this. If anyone is reading this and has found an alternative to halo that works with multiple spinners, please ping me.

@black-snow I think this project is no longer maintained, have a look at rich you may achieve the same using rich's spinner and Live Display
