( #3333=superdoc: print w/replies, xml ) Need Help??
I almost have a working example with overload, but i can't get it to work - wantarray is being fussy with me. The problem with overload though, is that you cannot define some new token such as /% - you have to use an existing one. This should get you started, but like i said, it doesn't work. I have provided a subroutine at the bottom that does work, i would appreciate it if someone could tell me what i did wrong. I chose * as the overloaded operator just to show that the overload sub is being called, i originally used %
package mod; use strict; use overload '*' => sub { my $div = int(${$_[0]} / ${$_[1]}); my $mod = ${$_[0]} % ${$_[1]}; return wantarray ? ($div,$mod) : $mod; }; sub new { my ($class,$val) = @_; return bless \$val, $class; } package main; use strict; my $i = mod->new(90); my $j = mod->new(60); my @x = $i * $j; my $x = $i * $j; print "@x\n"; print "$x\n"; my @y = mod(90,60); my $y = mod(90,60); print "@y\n"; print "$y\n"; sub mod { my $div = int($_[0] / $_[1]); my $mod = $_[0] % $_[1]; return wantarray ? ($div,$mod) : $mod; }; __END__ yields: 30 <-- this should be 1 30 30 1 30 30
