Rubyで一次元オートマトン

とりあえずルールとかみながらつくってみました。
次は生成関数から生成できるようにしたいとおもいます。

class World 

        def initialize(size)
                @map = Array.new(size, 0)
                @rule = Hash.new
        end

        def show
                @map.each do |cell|
                        if cell == 0
                                print " "
                        else
                                print "X"
                        end
                end
                puts
        end

        def cellNeighbors(idx)
                [
                        @map[idx-1],
                        @map[idx],
                        @map[(idx+1) % (@map.size)]
                ]

        end

                @map[idx] = n
        end

        def setRule(rule, n)
                @rule[rule] = n
        end

        private :cellNeighbors
