How to call a script with flags and get it's global vars?

Question

I'm looking for something like this require "peacefullscript.pl -whiteflag"; the problem that this one doesn't work. What I want is to call a script with some flags and get the global variables it creates into the current script.

How can I do this easily?

Answer 1

{
    local @ARGV = ("-whiteflag");
    do "peacefullscript.pl";
}

The local keyword creates a temporary copy of @ARGV that won't overwrite your original command line arguments.

Answer 2

@ARGV = ("-whiteflag");
require "peacefullscript.pl";
