The following example is from Little Book of Ruby in Chapter 9 and is
in the file modules4.rb:
# Ruby Sample program from www.sapphiresteel.com / www.bitwisemag.com
module MagicThing
def m_power
return @power
end
def m_power=(aPower)
@m_power=aPower
end
end
module Treasure
attr_accessor :value
attr_accessor :insurance_cost
end
class Weapon
attr_accessor :deadliness
attr_accessor :power
end
class Sword < Weapon
include Treasure
include MagicThing
attr_accessor :name
end
s = Sword.new
s.name = "Excalibur"
s.deadliness = 10
s.power = 20
s.m_power = "Glows when Orcs Appear"
puts(s.name)
puts(s.deadliness)
puts(s.power)
puts(s.m_power)
When run, it produced the following output:
>ruby modules4.rb
Excalibur
10
20
20>Exit code: 0
I had expected it to produce the following output:
>ruby modules4.rb
Excalibur
10
20
Glows when Orcs Appear>Exit code: 0
I do not understand why it is behaving the way it is behaving. Can
someone help me figure out why? I know that this is a Rails only
forum, but I don''t know of any other place to post my questions to. If
someone can point me to Ruby forum, I would gladly to to it.
Thanks in advance.
