The script uses a module I found here on PM called PerlMonks::StatsWhore. I think I may have made some minor changes. This is my version:
package PerlMonks::StatsWhore;
# Three Scripts for the Acolytes under the sky,
# seven for the Friar-lords in their halls of stone,
# nine for Mortal Bishops doomed to die,
# one for the Dark Saint on his dark throne
# in the Land of Monkwhore where the Black Stats lie.
# One Mod to rule them all,
# one Mod to find them,
# one Mod to bring them all
# and in the darkness bind them
# in the Land of Monkwhore where the Black Stats lie.
#
#
# Mucho original code by jcwren and larryl
# Objectified, merged, and tweaked by mojotoad
#
# Based on statswhore.pl, xstatswhore.pl, parts
# of luke_repwalker.pl and xluke_repwalker.pl
#
# See the POD for instructions.
#
# This code is public domain. Feel free to contact jcwren with tales
# of interesting applications.

=head1 NAME
PerlMonks::StatsWhore - Perl module for tracking node stats on www.per
+lmonks.org
=head1 SYNOPSIS
use PerlMonks::StatsWhore;
# Default relies on XML ticker and XML::Twig
my $sw = PerlMonks::StatsWhore->new(
user => 'username',
password => 'password',
);
print $sw->summary_as_string;
print $sw->histogram_as_string;
# If you do not want to mess with XML::Twig, or are having
# trouble with odd characters in titles, fall back to
# HTML pages and HTML::TableExtract
my $sw2 = PerlMonks::StatsWhore->new(
user => 'username',
password => 'password',
mode => 'HTML',
);
print $sw->summary_as_string;
# Or pull statistics directly
print "User: ", $sw->user, "\n";
printf( "Average reputation: %5.2f\n", $sw->average );
printf( "Minimum reputation: %d\n", $sw->repmin );
printf( "Maximum reputation: %d\n", $sw->repmax );
printf( " Total reputation: %d\n", $sw->reputation );
=head1 DESCRIPTION
PerlMonks::StatsWhore fetches and calculates the reputation of your
nodes on www.perlmonks.org. The module encapsulates the functionality
and much of the code from the scripts C<statswhore.pl>,
C<xstatswhore.pl>, C<luke_repwalker.pl>, and C<xluke_repwalker.pl>
written by B<jcwren>, including the histogram code provided by
B<larryl>. The module has the advantage of allowing you to select eith
+er
XML or HTML fetch modes -- XML, the default, is faster. For those peop
+le
that have trouble installing XML::Twig(3) and its associated libraries
+,
choose HTML mode which uses traditional HTML page fetches and
HTML::TableExtract(3). If XML seems to be having problems with parsing
+ node titles due to "odd" characters, then use HTML and things should
+ work as intended.
If behind a proxy, set your C<html_proxy> environment variable to the
+URL of your proxy server, as per L<LWP::Simple>
=head1 METHODS
=over
=item new()
Return a new PerlMonks::StatsWhore object. Valid attributes are:
=over
=item user
PerlMonks account name.
=item password
Password for perlmonks account.
=item mode
Fetch mode. Valid choices are 'XML' and 'HTML' (case sensitive). XML
mode requires XML::Twig(3), XML::Parser(3), etc. HTML mode requires
HTML::TableExtract. XML mode is much faster and is the default mode.
=item binsize
Specifies the resolution of each bar of the histogram. Default 5.
=back
=item user()
=item password()
=item mode()
=item binsize()
Access or set the associated parameter.
=item summary_as_string()
String detailing username, article count, and reputation (total, min,
max, average)
=item histogram_as_string()
String depicting a histogram of article frequency vs. reputation.
=item repmax()
=item repmin()
=item reputation()
=item average()
Return relevant statistics for the current writeup list. Automatically
fetch writeups if not fetched already.
=item reset()
Resets summary statistics and writeup cache -- subsequent queries will
fetch a new list of writeups.
=item writeups()
Returns a list of writeup descriptors. Each is a reference to a hash
with the following keys: C<nodeid>, C<title>, C<rep>, C<date>
=item writeups_ref()
Returns a single reference to a hash of writeups, keyed by C<node_id>.
=item node_ids()
Returns a list of node_ids for all writeups -- suitable for use as key
+s
in the writeups_ref() hash.
=back
=head1 REQUIRES
LWP::Simple(3), XML::Twig(3) (only for XML mode), HTML::TableExtract(3
+) (only for HTML mode)
