I Ching allows you to easily cast hexagrams from _The Book of Changes_
-
Utilizes the Yarrow Stalk casting method described in the appendix of _The I Ching (or Book of Changes)_ by Richard Wilhelm.
-
Names and rudimentary descriptions for all generated hexagrams.
-
Easily determine the nuclear trigrams of a given hexagram.
-
Easily determine if a hexagram is moving, obtain the moving lines, or generate the changed hexagram.
-
Render a hexagram to a string.
-
Further tests, optimizations, beautification.
Casting hexagrams is easy:
require 'iching' cast = IChing::Cast.new cast.hexagrams.each do | hexagram | puts puts hexagram.to_s puts hexagram.description[:name] hexagram.moving_lines.each { | line | puts "Lines #{ line }" } end
Example output:
------- ------- --- --- ------- ---x--- --- --- Chien Lines 2 ------- ------- --- --- ------- ------- --- --- Sun
Once cast, you can query a hexagram for details:
cast = IChing::Cast.new hexagram = cast.hexagrams.first puts hexagram.to_s ------- ------- --- --- ------- ---x--- --- --- puts hexagram.description[:name] Chien puts hexagram.moving_lines 2 puts hexagram.signature.to_s 001011 puts hexagram.top_trigram.to_s ------- ------- --- --- puts hexagram.top_trigram.description[:name] Sun puts hexagram.top_trigram.signature.to_s 001 puts hexagram.bottom_trigram.to_s ------- --- --- --- --- puts hexagram.bottom_trigram.description[:name] Ken puts hexagram.bottom_trigram.signature.to_s 011
