 The real problem, I think, it's that you are working with local variable. 
With your def :

  def output
    puts "I am snippet1 var is: #{var}"
    puts var2.inspect
    puts "joe"
  end

 When ruby will compile this def, "var" and "var2" will always be (in this
example) a method and not a local variable (in reality for "var", this is
when ruby compile the first time the string 
"I am snippet1 var is: #{var}").

 You can define a method_missing in JotsOutput

   class JotsOutput
     def method_missing(*args)
        ''
     end
   end

 to avoid the NameError, but after var and var2 must be defined as method
 also if you want to re-use this same 'def output' with another values for
 var and var2
