Subject: [ruby-talk:11357] binding to callers namespace.


Hi,

Am I using caller wrong here?  Basically I want to give
Display.render access to the callers variables:

class Object
  def getBinding 
    return binding() 
  end 
end

class Display
  def render
    caller.getBinding
    puts "secret is #{@secret} var is #{var}"
  end
end

class Demo 
  def initialize(n) 
    @secret = n 
  end 
  
  def display
    var = "asdf"
    d = Display.new
    d.render # want to give it access to @secret and "var"
  end
end 

k1 = Demo.new(99) 
k1.display

:in `render': undefined local variable or method `var'
  for #<Display:0x80fcd1c> (NameError)
        from ./binding.rb:24:in `display'
        from ./binding.rb:29

thanks,
