Subject: Re: Variable Dump

this clumsy script gets you part of the way there.
maybe somebody else knows a recursive solution.


#!/usr/bin/env ruby

$top_level = binding

   class Binding
     def info_vars(b = self)
	  vars = eval("local_variables", b)
           vars.each { |v| puts %(#{v} --> #{eval(v, b).inspect}) }
     end
   end

   def foo_def
     inside_foo_def = "hello there"

     binding.info_vars
     puts "\n# top level:"
     binding.info_vars $top_level
   end

foo = 'hello'
bar = "goodbye"
array = [ 'one', 'two' ]
foo_def()
