unconventional genetics, aggressively metaprogrammed. Pronounced like genie.

Installation

Add this line to your application's Gemfile:

gem 'jinni'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jinni

Quick-Start

Make a class

class Fish < Jinni::Creature
    # attr_genetic name, min, max
    attr_genetic :pointiness, 0, 1
    attr_genetic :mass_in_kilos, 10, 100
    attr_genetic :speed_in_knots, 8, 12

    # must return a fixnum
    def fitness
         @pointiness + (@speed_in_knots / @mass_in_kilos )
    end
end

Have an offspring

bill = Fish.random_new
ted = Fish.random_new

child = bill << ted

Put some creatures in a genepool

fishes = Jinni::Genepool.new
10.times { fishes.push(Fish.random_new) } # `random_new` respects min and max

have some more offspring

bill = fishes[0]
ted = fishes[1]

child = bill << ted

Start a whole new generation

generation = fishes.generate(10)
fishes << generation
