Counter placeholder not being removed upon clearing counter.

[SKnight79]

I created a test python program using the enlighten progress bar module that will generate 10 progress bars in threads, with random counters. They will load and run independently but attached to a manager. Once the counters complete, they are removed. The issue is that it leaves a blank line. Is there any way to remove that behavior?

import time, enlighten, random
from threading import Thread, Event

manager = enlighten.get_manager()
status_bar = manager.status_bar('Test', color=random.randrange(255), justify=enlighten.Justify.CENTER)
prefix = '[test]: '
counters = list()

global_threads = list()


def create(*args, **kwargs):
    counter = kwargs['counter']
    rand = kwargs['rand']
    counter.refresh()

    for num in range(rand+1):
        time.sleep(1)  # Simulate work
        counter.update()

    counter.close()

for id in range(10):
    rand = random.randrange(20)
    print('Creating counter {}'.format(id))
    counter = manager.counter(
        total=rand,
        desc='Counter ' + str(id),
        unit='seconds',
        color=random.randrange(255),
        leave=False,
        bar_format='{desc}{desc_pad}{percentage:3.0f}%|{bar}| {count:{len_total}d}/{total:d} [{elapsed} < {eta}]'
    )

    thread_kwargs = dict()
    thread_kwargs['counter'] = counter
    thread_kwargs['rand'] = rand
    counters.append(counter)

    thread = Thread(target=create, kwargs=thread_kwargs)
    global_threads.append(thread)
    thread.start()
    time.sleep(1)

for num in range(20):
    time.sleep(1)  # Simulate work
    print('Counters are running. Interval is {}'.format(num))

manager.stop()
print('Counter manager stop.')

I made a few changes while testing.

for num in range(rand+1):

Should be

for num in range(rand):

If rand is 3, then range(rand) would yield 0, 1, and 2. With range(rand + 1), you would also get 3 and that would exceed the total for the counter.

for num in range(20):
    time.sleep(1)  # Simulate work
    print('Counters are running. Interval is {}'.format(num))

Can probably be better expressed as

start = time.time()
while any(thread.is_alive() for thread in global_threads):
    time.sleep(1)  # Simulate work
    print(f'Counters are running: {time.time() - start:.2f} seconds.')

Not required, but more flexible

counter.close()

If you want to blank the line, change this to

counter.close(clear=True)

As far as removing the blank or completed lines, Enlighten currently only does that when adding new counters, since that's when the positions get calculated, but I can definitely see wanting to do it as the threads finish. I can add that when I get a chance.

I like the code improvements. Thanks! Look forward to the additions you mentioned.

As of 1.12.0, counter positions are now recalculated when a counter is closed.
