Re: Short quines

Here's mine quine.

use strict; #yesindeed
use LWP;
use HTTP::Request;
my $ua = LWP::UserAgent::new ('LWP::UserAgent');
LWP::UserAgent::agent ($ua, 'Mozilla/5.0');
my $url = "http://www.perlmonks.org/?node_id=662014";
my $request = HTTP::Request::new ('HTTP::Request', GET => $url);
my $response = LWP::UserAgent::request ($ua, $request);
my $page = $response->content;

my $beginning = q/use strict/;
my $end = q/q.positively./;
$page =~ /($beginning.*$end)/s;
my $code = $1 . "\n";
print $code; 
q!positively!

If you use <code> tags your quine becomes much simpler:

use strict; 
use LWP;
use HTTP::Request;
my $ua = LWP::UserAgent::new ('LWP::UserAgent');
LWP::UserAgent::agent ($ua, 'Mozilla/5.0');
my $url = "http://www.perlmonks.org/?displaytype=displaycode;node_id=6
+62072";
my $request = HTTP::Request::new ('HTTP::Request', GET => $url);
my $response = LWP::UserAgent::request ($ua, $request);
print $response->content;

Also, you don't break formatting for replies to your node.

Edit: I think you want a question mark after dot-star. Otherwise it's q-positively trivial for me to break your code.

Edit2: I just realized that, if you put a question mark after dot-star, the end of your regex matches itself. But there are ways around that.

As the title of this thread is "short quines", let me shorten that code a bit.

use LWP::Simple;getprint"http://tinyurl.com/ynp5kp"

Update: fixed code. It should now work.

Update 2012-05-24:</c> see also Usually J.A.P.H..

[Snarius]

I tried using <code. It renders > as & gt; or something. I actually tried to eliminate the >'s from my code, which is why there are lines like LWP::UserAgent::request ($ua, $request); instead of $ua->request ($request);.

[ambrus]

I'm quite sure that the displaytype=displaycode cgi argument makes perlmonks return the code as plain text, not HTML, so the angle brackets shouldn't be a problem.

Let me try.

use warnings; use strict;
my $u = "http://perlmonks.com/?node_id=662172;displaytype=displaycode"
+;
use LWP; print LWP::UserAgent->new->get($u)->content;

[Your Mother]

It seems to be broken...

use strict;
my $code = "death to dot star!\n";
print $code;

update: jdalbec already re-broke the code. Just noting it was silently updated -- boo! -- after I showed it broken the first time.
