XP is just a number

Looking for ideas to not have a totally bare website, I recently wrote a program that gathers my XP and number of posts on perlmonks, and plots the information.

The program below is run nightly from cron.


#!/usr/bin/perl use strict; use warnings; use POSIX 'strftime'; use Date::Calc qw /Today Delta_Days/; use LWP::Simple; sub plotme; my $outdir = "/home/abigail/WWW"; $outdir = "/tmp" unless -d $outdir; my $output = "$outdir/monks.html"; my $outfile = "$outdir/Images/monks.png"; my $data = "$outdir/Data/monks.dat"; sub logme { my ($xp, $arts) = @_; my $today = strftime "%Y-%m-%d" => localtime; open my $fh => "+<", $data or die "Failed to open $data: $!\n"; my $first_line = <$fh>; my $first_date = (split /:/ => $first_line, 2) [0]; while (<$fh>) { my ($date, $xp, $arts) = split; if ($date =~ /^$today/) { close $fh; return $first_date; } } printf $fh "%s: %6d %6d\n" => $today, $xp, $arts; close $fh or die "Failed to close $data: $!\n"; return $first_date; } my $url = ""; my $content = get ($url) or die "Failed to fetch $url\n"; my ($since) = $content =~ m!<td>User \s+ since:</td> \s+ <td>([^<]+)</td>!x; my ($exp) = $content =~ m!<td>Experience:</td> \s+ <td><b>(\d+)</b></td>!x; my ($arts) = $content =~ m!<td>Writeups:</td> \s+ <td><b><a[^>]+>(\d+)</a></b></td>!x; die "Failed to find 'User since'.\n" unless defined $since; die "Failed to find 'Experience'.\n" unless defined $exp; die "Failed to find 'Write ups'.\n" unless defined $arts; unless ($since =~ /([A-Z][a-z]+)\s+(\d+),\s+(\d+)/) { die "Failed to parse $since.\n"; } my %M = qw /Jan 1 Feb 2 Mar 3 Apr 4 May 5 Jun 6 Jul 7 Aug 8 Sep 9 Oct 10 Nov 11 Dec 12/; my ($month, $day, $year) = ($M {$1}, $2, $3); my $start = "$2 $1 $3"; my $nr_of_days = Delta_Days $year, $month, $day, Today; my $exp_per_day = sprintf "%.1f" => $exp / $nr_of_days; my $arts_per_day = sprintf "%.1f" => $arts / $nr_of_days; my $exp_per_art = sprintf "%.1f" => $exp / $arts; my $first_log = logme $exp, $arts; my ($s_y, $s_m, $s_d) = split /-/ => $first_log; $first_log = strftime "%e %B %Y" => 0, 0, 0, $s_d, $s_m - 1, $s_y - 19 +00; plotme; # # HTML generating stuff. # my $now = strftime "%e %B %Y" => localtime; open my $of => ">", $output or die "Failed to open $output: $!\n"; select $of; print << "--"; <html> <head><title>Perl Monk Postings</title></head> <body> <a href = "/">Home</a> <hr> <h1>Perl Monk Postings</h1> <p> I'm a frequent poster on <a href = "">Perlmonk +s</a>. My first post dates from $start. Since then, I gathered $exp experienc +e points, writing $arts posts. This comes to $arts_per_day articles per +day on average, and $exp_per_day experience points per day. <p> It doesn't account to $exp_per_art experience per article, because you can get heaps of experience for just connecting to the site, or voting on other people. <p> Below is a graph showing the experience progress since $first_log. <p align = "center"> <img src = "Images/monks.png" alt = "Perlmonks experience points"> <p> It should be noted that experience points don't mean anything. <p> <hr> <div align = "center"> <table><tr><td> Copyright 2003 by Abigail.<br> Page last modified: $now.<br> Comments to: \$web\$\ </td></tr></table> </div> </body></html> -- close $of or die "Failed to close $output: $!\n"; chmod 0644 => $output or die "Failed to chmod $output: $!\n"; sub plotme { open my $plot => "| gnuplot" or die "Failed to open pipe: $!\n"; print $plot <<"--"; set terminal png color set out "$outfile" set xdata time set timefmt "%Y-%m-%d:" set key left top Left reverse samplen 2 title "Legend" box set grid xtics ytics set xtics nomirror set ytics nomirror set y2tics nomirror set yrange [0:] set y2range [0:] set ylabel "XP" set y2label "Postings" plot "$data" using 1:2 smooth unique axis x1y1 title "Perlmonks +XP", \\ "$data" using 1:3 smooth unique axis x1y2 title "Nr of post +ings" -- close $plot or die "Failed to close pipe: $!\n"; chmod 0644 => $outfile or die "Failed to chmod $outfile: $!\n"; } __END__ This program is copyright 2003 by Abigail.
