hello all,

I am a newbie to ruby.

how do I override a method from a particular class (in std class lib), just
for one program, without modifying the class.

Thanks in advance for all your help.

-Jer A.

Just re-write it in your program where it's needed.

class Foo
def bar
//method to override
end
end

Very simple.

Just to clarify, you can define or redefine methods of core classes:

Class String
def inspect
"This string's value is \"#{self}\""
end
end
