pbarpool 0.0.2

pbar-pool
A straightforward, dependency free way to update multiple progress bars with python's multiprocessing library.
Specifically designed to work with multiprocessing.Pool - for which I found all other available solutions to be either overcomplicated, or completely broken.
Installation:
pip install pbar-pool

Usage:
from multiprocessing import Pool, cpu_count
from pbar_pool import PbarPool, Pbar
import time, random

def fn(x):
for _ in Pbar(x, manager=pbars, name=f'Process {pbars.id()}', color=(255, 0, 0)):
time.sleep(random.randint(0, 3))

to_process = [list(range(10)) for _ in range(100)]
pbars = PbarPool(width=100)

with Pool(processes=cpu_count(), initializer=pbars.initializer()) as p:
global_pbar = Pbar(p.imap_unordered(fn, to_process), manager=pbars, name='global', total=len(to_process))
for _ in global_pbar:
pass

it's as simple as adding the initializer=pbars.initializer() option to your Pool object to give each Pool process access to the global progress bars pool.
Then, in each process, wrap your iterator in a Pbar() object, passing in the global PbarPool object as the manager argument.
You can also add a global progress bar to track the progress of the outer function, as seen in the example above.
