Binary Code

I realize this is the second mailing list-mining for content this week but this was too cool to not mention. Over in Ruby Forum in using the current method name within current method Aleks Kissinger, Robert Klemme, and Matt Todd hashed out a way for methods in Ruby 1.8 to know their own identity.

To jump to the end, the final solution is:

module Kernel
private
   def this_method
     caller[0] =~ /`([^']*)'/ and $1
   end
end

As an example:

class TestClass
   def this_methods_name
      puts this_method
   end
end

t = TestClass.new
t.this_methods_name

Pretty cool stuff, that.
