reloading required modules in irb

Heikki Kupiainen

Hi,

I use irb to evaluate my code while programming.
So it is easy to test my class this way:

> require "my_class"
> c = MyClass.new
> c.some_method

But the problem occurs when I now edit the class adding a new method
"new_method". If I then type:

> c.new_method
NoMethodError: undefined method :'new_method'

How can i now re-require "my_class" without restarting irb?
typing again the require command doesn't seem to reload MyClass:

> require "my_class"

Nothing happens! The class is not reloaded into memory.

Please tell me somebody how I can refresh the required class!
