A question about require

ruby-talk
1

Hello,

I was wondering what is the best way to “re-require” a file in ruby. In
my code, I have a function that looks like this:

def LoadAndExecute
require 'script_that_has_foo_in_it.rb’
foo
end

If I executre that function once, then modify the script_that_…rb and
re-execute the LoadAndExecute function without stopping everything, the
script file isn’t reaquired and foo re-execute the old code. I have
added the following line before require ‘…rb’

$".delete “script_that_…rb”

and it works fine but I want to make sure that it’s a valid way of doing
"re-require".

Thankx,
Ben.

load (as opposed to require)

Sounds like you would be better of with just using Kernel#load
