apytl 0.0a7

A bawdy, emoji-friendly progress bar.

Another Python Terminal Logger

Here it is: another python terminal logger---apytl.

This implementation uses only the standard Python library and supports unicode emojis. If you've ever wanted a progress bar that fills with piles of poop, eggplants, or extended middle fingers, then you're in the right place.

Installation

pip

I've attempted to make this easy. You should be able to use pip to install the package by running:

pip install apytl

Right now the package is only released for Python >=3.5. If pip complains about not finding a version, you can either try upgrading Python, or build from source.

Building from source

You may install from source by either downloading the files from PyPI (here) or cloning the git repository:

git clone https://github.com/anadolski/apytl.git

If this is the first time you're installing the package, all you should need to do is cd to the source directory (i.e., the one containing setup.py) and run:

python setup.py build
python setup.py install --user --record ./.installed_files.txt

If you re-clone the repo (or git pull or otherwise update the source code), you will need to reinstall to take advantage of all the fun new features. And bugs. Let's not forget those bugs. To reinstall---again, from the source directory---run:

rm $(cat ./.installed_files.txt)

(Note: This command will attempt to delete every entry in .installed_files.txt, so use with caution. Ensure there isn't anything important hiding in that file.)

To reinstall, simply run the build and install commands mentioned at the beginning of the section.

Use

You can use the progress bar for iteration tracking. All the function needs to know is the total number of iterations in the loop, and the iteration that it is currently on. Just drop the apytl.Bar().drawbar() function inside your loop and pass it those parameters. Here's a minimal example:

import time
import apytl

total_iterations = 25
wait = 0.1

for index, value in enumerate(range(total_iterations)):
    # Your code goes here, then we draw the progress bar
    apytl.Bar().drawbar(value, total_iterations)
    time.sleep(wait)

But you probably want emojis, so do this instead:

import time
import apytl

total_iterations = 25
wait = 0.1

for index, value in enumerate(range(total_iterations)):
    # Your code goes here, then we draw the progress bar
    apytl.Bar().drawbar(value, total_iterations, fill='poop')
    time.sleep(wait)

Ta-da! Poop all over your terminal (assuming the combination of your display manager, terminal emulator, and font supports it).

apytl.Bar().drawbar() accepts some customization options; see the docstring for complete details. Here are a couple highlights:

• fill: takes arbitrary single-character alphanumeric input, or an arbitrary Python-formatted unicode emoji (of the form \\UXXXXXXXX or \\uXXXX), or one of a few preset options listed in the docstring.
• barsize: takes an integer and sets the size of the filling region.

Development

This package is an alpha release and under active development. That means that I fix bugs and create new ones approximately whenever I feel like it.

The master branch is the most stable version of the package, with primary development happening on dev.

Pull requests and issue tickets are both welcomed and encouraged. Please put specific emoji requests into issue tickets (for now).
