Ruby Hexdump method for Class String



This is a small extension for the Ruby class String, which provides a hexdump method to display string contents as a hexdump..

It takes one optional boolean parameter, to determine if you want to print series of zeros, or if you want to colapse them. 



	# irb
	irb(main):001:0>  require 'hexdump'
	=> true
	
	irb(main):002:0> s = "some random string" << "\0"*46 << "some more stuff"
	=> "some random string\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000some more stuff"
