I use Fraser Valley Regional Library a lot (BC Canada). The library allows me to check online whether I have any book due, but it is a pain to key in bar code, password, etc every time, and the library does not provide the service of sending me email alert whether I have any book due. So I come up with this little script to help myself.

use LWP::UserAgent;
#Time::localtime is not really used
use Time::localtime;
use Data::Dumper;

use strict;
use warnings;

my $data = [
                ["name" => "Liz", "code" => "1234567890", "pin" => "06
+09"],
                ["name" => "Peter", "code" => "1234567890", "pin" => "
+0609"],
                ["name" => "Jimmy", "code" => "1234567890", "pin" => "
+0609"],
           ];
my @books = ();

my $today = sprintf("%02d-%02d-%02d", localtime->mday(), localtime->mo
+n(), localtime->year() % 100);
print "Today is: " . $today . "\n";

my $ua = new LWP::UserAgent();
for my $index (0 .. $#{@$data}) {
    my $res = $ua->post("http://catalogue.fvrl.bc.ca/patroninfo.asp", 
+$data->[$index]);
  
    my $content = $res->content();
    $content =~ m/\/(\d{1,})\//s;
    parse($ua->post("http://catalogue.fvrl.bc.ca/patroninfo/$1/patfram
+eitems", $data->[$index]));
}
sort_book();
print Dumper(\@books);


sub parse {
    my $response = shift;
    my $content = $response->content;
    $content =~ m/<table.*?>(.*?)<\/table>/s;
    $content = $1;
    my @items = split /checkbox/, $content;
    for (1 .. $#items) {
        my $item = $items[$_];
        $item =~ m/\)">(.*?)<\/a>/s;
        my $description = $1;
        $item =~ m/DUE (.{8})/s;
        my $due = $1;
        push @books, $due. "\t" . $description;
    }
}

sub sort_book {
    @books = sort {
        $a =~ /(\d*)-(\d*)-(\d*)/;
        my $keya = "$3$2$1";
        $b =~ /(\d*)-(\d*)-(\d*)/;
        my $keyb = "$3$2$1";
        return $keyb cmp $keya;
    }
    @books;
}
