Overview
========
Enlighten Progress Bar is a console progress bar library for Python.
The main advantage of Enlighten is it allows writing to stdout and stderr without any
redirection or additional code. Just print or log as you normally would.
Enlighten also includes experimental support for Jupyter Notebooks.

Conda
-----
.. code-block:: console
$ conda install -c conda-forge enlighten
Examples
========
Basic
-----
For a basic status bar, invoke the Counter_ class directly.
.. code-block:: python
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.
.. code-block:: python
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:
.. code-block:: python
import time
import enlighten
counter = enlighten.Counter(desc='Basic', unit='ticks')
for num in range(100):
time.sleep(0.1) # Simulate work
counter.update()
