lowbar 0.1.6

The simplest loading bar for python.

lowbar

The simplest no-nonsense loading bar for python.

demo.py

# All the sleep calls would be tasks to
# complete in a real program


import lowbar, time, random


bar = lowbar.LowBar()


completion = 0


for i in range(10):
    time.sleep(random.random())
    bar.update_smooth(completion)
    bar.log(f"Task {i+1} completed")
    completion += 10
bar.clear()


print("\nRunning checks...")
bar.update(0)
time.sleep(1)
bar.update_smooth(10)
time.sleep(2)
bar.update_smooth(40)
time.sleep(2)
bar.update_smooth(100)
bar.clear()
print("Tasks complete!")

Installation

Install the latest stable release:

python3 -m pip install lowbar

Or build the development version:

git clone https://github.com/AnnikaV9/lowbar.git
cd lowbar
python3 -m pip install build hatchling
python3 -m build -w
python3 -m pip install dist/lowbar-*-py3-none-any.whl

Usage

Once you have lowbar installed, you can import it like any other module:

import lowbar

And initialize the bar:

bar = lowbar.LowBar()

To make the bar visible, simple update the completion percentage:

bar.update(0)

We start with 0 since our program hasn't completed anything yet.

After completing some tasks, we can increase the bar's completion percentage:

bar.update(20)

The above function will immediately move the bar to 20%. To use a more smoother but slower animation:

bar.update_smooth(40)

Using print() or other similar functions will push the bar up, which doesn't look nice. To log messages without affecting the bar:

bar.log("Hello World!")

And finally, to clear the bar completely:

bar.clear()

Here's an example usage of the bar:

import lowbar, time
bar = lowbar.LowBar()
completion = 0
for i in range(10):
    time.sleep(2) # This would be replaced with an actual task
    bar.update_smooth(completion)
    bar.log(f"Task {i+1} completed")
    completion += 10
bar.clear()
print("Tasks complete!")

You don't even need a loop:

import lowbar, time
bar = lowbar.LowBar()
bar.update(0)
time.sleep(1)
bar.update_smooth(10)
time.sleep(2)
bar.update_smooth(40)
time.sleep(2)
bar.update_smooth(100)
bar.clear()
print("Tasks complete!")

You can change the load fill and blank fill chars as well:

bar = lowbar.LowBar(bar_load_fill="O", bar_blank_fill=".")
