Hi,
Hello,
I have just moved a piece of code into a separate module. However, the
subroutine in the new module needs to reference a subroutine in the
script it's called from. Is there any way around this?
Basically, I am using AnyEvent::XMPP, and want the setup code in the
module. This code sets up which subroutines to call when certain events
occur, and all these will be in the calling script.
Can I pass the names of subroutines in the calling script to the
subroutine in the module somehow?
No, but you can pass a reference to a subroutine and then dereference it
in the module. For example:
$ perl -le'
sub test { print "@_" }
sub in_module {
my $sub_ref = shift;
$sub_ref->( "one", 2, "three", 4 );
}
in_module( \&test );
'
one 2 three 4
