Overview | ||
======== | ||
|
||
Enlighten Progress Bar is a console progress bar module for Python. (Yes, another one.) | ||
|
||
The main advantage of Enlighten is it allows writing to stdout and stderr without any | ||
redirection. | ||

Documentation | ||
============= | ||

|
||
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() | ||
Additional Examples | ||
------------------- | ||
* `basic <examples/basic.py>`_ - Basic progress bar | ||
* `floats <examples/floats.py>`_ - Support totals and counts that are ``floats`` | ||
* `multiple with logging <examples/multiple_logging.py>`_ - Nested progress bars and logging | ||
|
||
Customization | ||
------------- | ||
|
||
Enlighten is highly configurable. For information on modifying the output, see the | ||
Series_ and Format_ sections of the Counter_ documentation. | ||
