Examples

Basic

For a basic status bar, invoke the Counter class directly.

import time
import enlighten

pbar = enlighten.Counter(total=100, desc='Basic', unit='ticks')
for num in range(100):
    time.sleep(0.1)  # Simulate work
    pbar.update()

Advanced

To maintain multiple progress bars simultaneously or write to the console, a manager is required.

Advanced output will only work when the output stream, sys.stdout by default, is attached to a TTY. get_manager() can be used to get a manager instance. It will return a disabled Manager instance if the stream is not attached to a TTY and an enabled instance if it is.

import time
import enlighten

manager = enlighten.get_manager()
ticks = manager.counter(total=100, desc='Ticks', unit='ticks')
tocks = manager.counter(total=20, desc='Tocks', unit='tocks')

for num in range(100):
    time.sleep(0.1)  # Simulate work
    print(num)
    ticks.update()
    if not num % 5:
        tocks.update()

manager.stop()

Counters

The Counter class has two output formats, progress bar and counter.

The progress bar format is used when a total is not None and the count is less than the total. If neither of these conditions are met, the counter format is used:

import time
import enlighten

counter = enlighten.Counter(desc='Basic', unit='ticks')
for num in range(100):
    time.sleep(0.1)  # Simulate work
    counter.update()

Additional Examples

• basic - Basic progress bar
• context manager - Managers and counters as context managers
• floats - Support totals and counts that are floats
• multiple with logging - Nested progress bars and logging
• FTP downloader - Show progress downloading files from FTP

Customization

Enlighten is highly configurable. For information on modifying the output, see the Series and Format sections of the Counter documentation.
