Currently, two kinds of +automata are supported: Conway's Game of Life and Elementary Cellular Automata. +In both cases custom initial states can be loaded as well as the rules +governing the automaton's progress. + +····· How? ····································································· + +Install the Automata package by copying the content of the “module/” directory +into the “texmf-local” of your context distribution; e.g. + +$ cp -r modules/tex/ ~/context/tex/texmf-local/ + +if you happen to have the context minimals installed in you $HOME dir. + +Have a look at the usage examples to get an overview. The usage does not +significantly differ from the other styles the Simple Slides package provides. +You might want to tweak the color definitions in “simpleslides-s-Automaton.tex” +and adapt them for your particular use case. + +Also, try the command line tool “run.lua” from the directory “misc/”. Put it +to some safe directory together with the scripts from +“module/tex/context/third/simpleslides/automata/automata-eca.lua” and invoke it +on one of the examples: + +$ texlua run.lua --file=sships.gol --n=90 +$ texlua run.lua --file=w50m.eca --n=20 --rule=182 + +····· May I … ? ································································ + +This code is licensed under the GNU GPL v.2 (no later versions) as is the Simple +Slides module.
