Is there any way to start the Ruby debugger on exception?

Question

Is there any way to start the/a Ruby debugger whenever the code throws an exception, without me wrapping the code like this:

begin
  #do something
rescue
  d         


        

Answer 1

require 'ruby-debug'
class Exception
  alias original_initalize initialize
  def initialize(*args)
    original_initalize(*args)
    debugger
  end
end

This will run the original exception as well as call debugger
