(Golf) JAPH?

on May 17, 2001 at 04:28 UTC ( #81130=perlmeditation: print w/replies, xml ) Need Help??

There is a large number of J.A.P.H. programs floating around, but I am curious to know if they have ever been golf'd. Of course, most are elegant from a point of fantastic obfuscation, but not usually in terms of economy of characters. This, it seems, limits artistic expression.

Without the devious short-cut of calling the program "Just Another Perl Hacker" and then using:      print$0 As in, the name of the script is arbitrary, and as such, the code should be able to operate in a cut-and-paste capacity, just like most obfuscations.

The question is, is there anything more economical than:      print"Just Another Perl Hacker" Or, rather:      die"Just Another Perl Hacker\n" As far as I can tell, there is very little wiggle room.

    This question has been asked before. The original work can be found here. They got it down to
    die`man $^Xfaq1`=~/"(j.*)"/
    as opposed to
    die"Just Another Perl Hacker\n"
    It's not exactly a general solution and the formatting is a little off, but I'm very impressed.

    You always miss an obvious character:
    die'Just another Perl hacker '

    Hmm... not very portable, but:
    perl -042e'print((`$^Xdoc -qj`)[1])'
                   s aamecha.s a..a\u$&owag.print
      ...and not really shorter :

      die"Just Another Perl Hacker\n"
      perl -042e'print((`$^Xdoc -qj`)[1])'

    The following code will print a JAPH, occasionally:
    print chr rand 127 for 1..25
                   s aamecha.s a..a\u$&owag.print

    Sure. Same message, different words:
    That's 11 keystrokes of code accompanied by over 1000 characters of hidden description (there's sure room for some golf with the description).

    Going with the theory that you never really know where the lines are until you step over them, I submit die"$0\n" Of course, the file was named "Just Another Perl Hacker" ...

      I submit that the following is shorter:
      perl -pee
      Then start pressing the following keys: 'J', 'u', 's', 't' SPACE, 'A', 'n', 'o', 't', 'h', 'e', 'r', SPACE, 'P', 'e', 'r', 'l', SPACE, 'H', 'a', 'c', 'k', 'e', 'r', ENTER. Japhage magically occurs...
                     s aamecha.s a..a\u$&owag.print
      If you are going to go through this trouble, name the file "Just another Perl hacker,\n" and then reduce it to:
        Not quite. You need the "\n" at the end of the die() argument to keep it from spitting out the filename (again) and line number.

    Not shorter. perl -lpe '}$_="Just Another Perl Hacker";{' .
