Can module methods be aliased?

[arev]

Simple question Let's say I want to add one line of code to Input.update. Can it be done without rewriting the whole thing?

I don't know about the modules, but the hidden classes can't be aliased because you don't know what to aliasing.

That. But I mean, the modules are classes too, so you can alias them.

Sure you can.
The way I do it is by using an anonymous inner class. There might be others. In fact there probably is.

module Input
  class << self
    unless self.method_defined?(:zeriab_myscript_input_update)
      alias_method(:zeriab_myscript_input_update, :update)
    end
    def update
      @x ||= 0
      @x += 1
      p @x if @x % 100 == 0
      zeriab_myscript_input_update
    end
  end
end

@mephisto: Hidden classes can be aliased. If you don't know what to alias just use reflection to get that information.
