Another Push_swap visualizer (python + kivy)

A push_swap visualizer in python using the kivy library

This python script started as a small modification of o-reo push_swap visualizer when it was still using python.

I ended up doing a complete rewrite using the python kivy library.

This script is intended to visualize your work with the push_swap 42 project.

You need Python3 and kivy installed. You can install kivy this way:

python3 -m pip install "kivy[base]"

You can check the kivy doc for more advanced install steps (virtualenv...)

Place the script where you want. It will look for the push_swap binary in the current folder if no path is specified.

You can launch the script with :

python3 pswapviz.py

or this way if you want to point to a custom path for your push_swap binary with a 500 number stack

python3 pswapviz.py -p ../push_swap/push_swap -s 500

or this way if you want to give manually a specific list of numbers

python3 pswapviz.py -p ../push_swap/push_swap 1 3 2 8 7 5

In the interface you can:

• Adjust speed with the slider.
• Use the spacebar to start or stop the visualisation.
• Use left and right arrow to move forward or backward.
• Use esc key to quit
• Use the big slider to skip where you want in the move list.

Here is the full list of command line parameters :

python3 pswapviz.py [-h] [-s <size>] [-c] [-p <path>] [-g <id>] [Numbers ...]


positional arguments:
  Numbers               A List of numbers for push_swap to sort (optional)

optional arguments:
  -h, --help            show this help message and exit
  -s <size>, --stack-size <size>
                        Size of the stack of number (ex: 3 or 5 or 100 or 500) default 100.
  -c, --continuous      The number generated are folowing each other by a "1" increment.
  -p <path>, --push-swap <path>
                        The absolute or relative path to your push_swap binary. 
                        if the path is not specified, look for push_swap in the current dir.
  -g <id>, --gradient <id>
                        Chose a color gradient to use (value between 1 and 10). 
                        1 - rainbow blue to red,
                        2 - rainbow purple to red,
                        3 - black and white dark,
                        4 - black and white light,
                        5 - White to black,
                        6 (default) - red gradient to black,
                        7 - purple gradient to black,
                        8 - red gradient to white,
                        9 - white to purple, 
                        10 - sunset
