thirty-thirty¶ ↑

the right hand of Marshall BraveStarr

Selectively marshal objects without the fancy ruby 1.9 marshalling:

class Marshalled
  extend Thirtythirty

  marshalled_accessor :attr1, :attr2
  attr_accessor :transient_attr
end

original = Marshalled.new
original.attr1 = "value1"
original.transient_attr = "non-marshalled"

marshalled = Marshal.dump(original)

reloaded = Marshal.load(marshalled)

reloaded.attr1          # => "value1"
reloaded.transient_attr # => nil

Note: Custom marshalling will only be activated by calling one of the marshalling methods (marshal, marshalled_reader, marshalled_writer, marshalled_accessor), not by extending Thirtythirty alone.
