gol

An implementation of Conway's Game of Life. Accepts pattern files depicting a starting state with _ representing a dead cell and # representing a live cell (see the example files in gol_patterns/) and generates a given number of generations.

gol accepts two switches: -p tells gol to print the results to the terminal, whereas -i tells it to generate an animated GIF, <INPUT_FILE>.gif. Note that -i is dependent upon ImageMagick and gifsicle being installed.

Example usage (print the first 30 generations of tumbler.gol to the terminal):

gol -p gol_patterns/tumbler.gol 30
