Pixelist

Pixelist provides a simple command line application to manipulate pixel matrices stored in text files. It comes with a set of commands to create a matrix or set pixels and a set of workers which run algorithms on a pixel matrix.

The pixel matrix is stored in a text file, which can be edited in a text editor. Each character is representing one pixel.

There is a plugin framework which can be used to add workers which run on a pixel matrix. This can be used to implement algorithms such as Conway's Game of Life:

Pixelist Life (step 50)

|   OO   |
|  OO    |
|        |

Pixelist is meant for experimenting with algorithm which operate on a simple pixel matrix and learn or experiment with programming techniques such as TDD. If you find creative use for it, please let me know.

Running in docker

There is a Dockerfile you can use to build a container in which you can run pixelist. Build the container by executing a command like

docker build -t pixelist .

Then run the container with

docker run -t pixelist

This will execute the default command which runs the game of life.

To execute another command run it with a command such as

docker run pixelist bin/pixelist -p examples/life.pixels show
