RE: Post Election Day Perl

[amelinda]

A couple minor assumptions: lynx is in your path, sendmail is in your path, you only need to know who's on top and by how much. Why ass-u-me? lynx's dump is much easier to parse than the source of the page.

This version without use strict; or any errorchecking weighs in at 469 in the long form, and 429 in the most condensed form:

#!/usr/bin/perl -w
open I,"lynx -dump http://www.cnn.com/ELECTION/2000/results/FL/index.h
+tml|";
while(<I>) { @j = split; if($j[1]) {$j[1] =~ s/,//g;}
if (/Bush/) { $b = $j[1];} 
elsif (/Gore/) { $g = $j[1];} } 
close I; open O, ">out"; 
$d = abs($b-$g);
if ($b == $g) {$r="tied!\n";} 
$b < $g ? $r="Gore: $d\n" : $r="Bush: $d\n";
print O "$r"; close O;
open F,"mfile"; $m = <F>; close F;
open(M,"|sendmail -t"); print M <<E;
Subject: results
Cc: $m
$r
E
close M; exit;

This one has both use strict; and error checking (though it does still make the above assumptions). It comes in at 612 bytes (according to wc). When I gutted the whitespace, it crawled in at 561 bytes.

#!/usr/bin/perl -w
use strict; my $b; my $g; my $r;
die "lynx failed\n" unless open I,"lynx -dump http://www.cnn.com/ELECT
+ION/2000/r
esults/FL/index.html|";
while(<I>) { my @j = split; if($j[1]) {$j[1] =~ s/,//g;}
if (/Bush/) { $b = $j[1];} 
elsif (/Gore/) { $g = $j[1];} } 
close I; open O, ">log" or die "log failed\n"; 
my $d = abs($b-$g);
if ($b == $g) {$r="tied!\n";} 
$b < $g ? $r="Gore: $d\n" : $r="Bush: $d\n";
print O "$r"; close O;
open F,"mfile" or die "no mailfile\n"; my $m = <F>; close F;
open(M,"|sendmail -t") or die "couldn't sendmail\n"; print M <<E;
Subject: results
Cc: $m
$r
E
close M; exit;

And for sheer showing-off-ness, this is that shortest chunk:

#!/usr/bin/perl -w
open I,"lynx -dump http://www.cnn.com/ELECTION/2000/results/FL/index.h
+tml|";while(<I>){@j=split;if($j[1]){$j[1]=~s/,//g;} if(/Bush/){$b=$j[
+1];} elsif(/Gore/){$g=$j[1];}} close I;open O,">log";$d=abs($b-$g);if
+($b==$g){$r="tied!\n";} $b<$g ? $r="Gore: $d\n" : $r="Bush: $d\n";pri
+nt O "$r";close O;open F,"mfile";$m=<F>;close F;open M,"|sendmail -t"
+;print M <<E;
Subject: results
Cc: $m
$r
E
close M; exit

Heck, even if I don't win a tshirt, I'm pretty damn happy with getting this to work at ALL!
