Aliasing with 'loop do' stuff added.

[Kain Nobel]

Is there a certain way to alias a method with a 'loop do' command, especially a 'loop do' with 'if' and 'else' statements in it? Basically, I'm editing a script that copies and re-writes 3 or 4 default scripts, with additional information added into the methods.

I've prettymuch got alias_method down, but if you're trying to modify a 'loop do' with an alias method, how do you do it?

Spoiler: Example

def method
    # Some code before the loop
    loop do
      if @somecode == 1
        # Do Something 1
      elsif @somecode == 2
        # Do Something 2
      else
        # Do Something 3 (Added to the method)
      end
    end
  end

alias_method is only able to add code to the end of, or the beginning of the method being aliased. You can't alias a method and modify the code of the alias method. A risky maneuver would be getting the result and modifying it as necessary. I say risky because you are probably depending upon the result to equate to a certain range of answers. If anyone is using this same methodology they can alter the answer before it reaches your alias if the other one is encountered first.

Example:

class Test
  def alpha
    return true
  end
  alias beta alpha
  def alpha
    answer = beta
    return !answer
  end
end

But I suppose that risk is better than just overriding the method. Anyway back to the most important point and the question you actually asked. You can't modify the functionality of the alias_method directly. But if the resultant is returned you are more than welcome to it with some risks involved as well.

Good luck with it Kain Nobel! :thumb:
