Rug Maker

rug creates an image of a square weave rug colored using tricoloration or p-coloration rules from knot theory.

To install: go install git.sr.ht/~satchlj/rug

To run: rug <fringeFunction> <num>

Where fringeFunction is the function which determines the fringe of the rug and thus the entire coloration, and num is an integer which determines the size of the rug.

Currently the only options for fringeFunction are alternate and random.

You can also generate a difference diagram between two fringe functions using rug diff:

rug diff <fringeFunction1> <fringeFunction2> <num>

You can generate a rug or difference diagram which is p-colored instead of 3-colored by calling

rug <fringeFunction> <num> <p>

rug diff <fringeFunction1> <fringeFunction2> <num> <p>

rug will save a file to the working directory called <fringeFunction><num>.png. Colors are RGB.
