Subject: Re: [QUIZ][SOLUTION] Hash to OpenStruct (#81)

My solution was very simple:
require 'yaml';require 'ostruct';def h(h)h.map{|k,v|h[k]=Hash\
===v ?h(v):v};OpenStruct.new(h)end;puts h(YAML.load($<.read))

This can't deal with the recursion that MentalGuy(sorry for the wrong
capitalisation!) posted.
The following is basically the same code:
class Hash
  def to_ostruct
    copy = {}
    each do |(key,value)|
      if value.class == Hash
        copy[key] = value.to_ostruct
      else
        copy[key] = value
      end
    end
    OpenStruct.new(copy)
  end
end
I tried to look into changing YAML.load to make OpenStruct's instead of
hashes, but I soon gave up on that :)

j`ey
