Java's toString() for perl

Filed under: — Sven @ 15:11 IST

I post it here so I can find it again if needed again. Sometimes I just want to see everything that is going on in a perl object. Sort of what Java’s toString() function does when printing out maps or lists. This is what I ended up with. Now it’s public domain!

our $join = ' ';
sub to_string{ # ug, java
    my $s = shift;
    my $out;
    if (ref $s) {
	if ($s =~ m/ARRAY/) {
	    $out .= '[' . join($join, map {
	    } @$_) . ']';
	} elsif ($s =~ m/HASH/) {
	    $out .= '{' . join($join, map {
		"$_=" . to_string($s->{$_});
	    } keys(%$s)) . '}';
	} else {
	    $out .= $s;
	    warn "How do i display '$s'?";
    } else {
	$out .= quotemeta($s);
    return $out;

Many people may not get medical insurance and thus forced to pay for the expensive prescription medications or research how to buy generic medications online. Generic drugs are as safe as other branded counterparts. Only reputable pharmacy produces them such as German Remedies. With this in head one can buy revia uk in generic online drugstore including free shipping anywhere in the world
