Rails - Dec 2007 - pretty neat Mash class (Magic Hash)

class Mash < Hash
  def method_missing(name, value=nil)
    key = name.to_s.sub(/[=?!]$/,'''').to_sym
    self[key] = value if name.to_s[-1,1] == "="
    self[key] = Mash.new unless self[key] || value
    return self[key]
  end
end


Its like OpenStruct...so what can you do?

require ''pp''
m = Mash.new
m.first_name = "john"
m.last_name = "doe"
m.address.street = "somewhere drive"
m.address.city = "somecity"
m.address.state = "somestate"
m.address.zip = 12334
pp m

{:address=>
  {:state=>"somestate",
   :street=>"somewhere drive",
   :city=>"somecity",
   :zip=>12334},
 :first_name=>"john",
 :last_name=>"doe"}
