Question

I have two file tmp.pl and tmp2.pl. I want to call tmp2.pl with a require command but also send a parameter. Is there a better way of doing this?

tmp.pl

require "tmp2.pl" "passed parameter";

tmp2.pl

print @_;

Answer 1

There’s probably a better way to accomplish whatever it is you’re trying to do, but you could achieve your current sub goal with something like

{
    local @_ = ("passed parameter");
    require "tmp2.pl";
}

I might consider this idiom in a place where I wanted to run a perl script from within a perl script. That is, I could say

{
    local @ARGV = ("foo","bar");
    require "my_script.pl";
}

instead of

system("perl","my_script.pl","foo","bar");

(There are plenty of subtle and not-so-subtle differences between these two calls, so a lot depends on what “features” of these calls you need)
