    Beautiful, absolutely beautiful...

    Heh, almost had me, til I noticed the sig handler and the Fatal warnings.

      It got a few people. It was actually considered, thought to have been posted to the wrong section. Now that's obfu!

    What exactly are the error messages it is supposed to get? With different perls I'm seeing
    g teatedther Perl hacker justtor not tlwp d2.ate g Perl hacker
    Update: hid the partial output I got
      Like others have pointed out, it is highly dependant on your os and perl version, hence my bold disclaimer. For starters, it will only work on win32 because it relies on a case-insensitive filename bug. v5.8.3 works for me.
      printf "%-s", "getting perlmonks nodes\n"; my $node = { node1 => qw(The Monastery Gates), node2 => qw(Seekers of +Perl Wisdom) }; use lwp v5.75; require $$; if( defined( my %pid ) ) { $pid{ fork() or die } = 1 } my $html = connect '$node', 10; print html, "\n"; 16 4 Newline in left-[just]ified string for printf 25 4 Odd number of elements in[ ano]nymous hash 15 5 lwp defines nei[ther ]package nor VERSION--version check failed 0 5 [Perl ]v2916.0.0 required (did you mean v2916.000?)--this is onl +y v5.8.3, stopped 9 2 defined(%[ha]sh) is deprecated 24 3 connect() on unopened so[cke]t +?node=$node 21 1 No comma allowed afte[r] filehandle

      use japh; print;
        You should use
        <table bgcolor="white"><tr><td><font color="white"> ... </font></table>
        to hide that, since some themes will have a non-white bg.

    require $$;

    This line looks so good (although I don't quite know what it does).

    Update: Very good japh. Almost works on linux too, I get just Perl hacker

    On my WinXP system, running ActivePerl 5.8.2, I get this:
    justtor ther Perl hacker
      It's because you copied/pasted the code form the page. Use the d/l code link instead to get the code so you don't get perlmonks' code wrapping in there.

    OK I don't get it... It prints this:

    getting perlmonks nodes
    emen:VERfine defin oilei

    OK And?? What does it mean??

    perl -le '$cat = "cat"; if ($cat =~ /\143\x61\x74/) { print "Its a cat +!\n"; } else { print "Thats a dog\n"; }'
      emen:VERfine defin oilei

      I get "g teatedfine Perl al" -- The output is dependent on your Perl version and operating system.

      It's a clever concept, regardless.

    I see mine are not the only obfus that the 5.10.0 release of perl completely breaks. That release has

    removed the "Newline in left-justified string for printf" warning.

    Update: oh sorry, replied to the wrong post. This is meant as a reply to can someone help me?. Update: Arunbear has moved the node to the right place. Thanks.

    I just noticed that this obfu was posted only a few days after Larry Witticisms from perl Errors, which is similar in that

    it too depends on the exact error message strings perl generates.

    That can't be a coincidence.
