Obfuscated code

( #1597=superdoc: print w/replies, xml ) Need Help??

Got some code which would take a Perl grand master to understand without running it? Post it in this section so we can stare at it in awe.

Word of warning, though: Don't be too cocky with your post — almost inevitably someone will post a reply that does the exact same thing in even fewer characters!

    Not much obfuscation really. The idea was to try and see if it was possible with some unusual code to predecrement a constant or at least to pretend to do so.

    60 byte solution, not counting hashbang, to take strings that look like '2d4' or '2d4+10' and give you the result:

    -n ($d,$s,$=)=split/d|\+/;$=+=1+rand $s for 1..$d;print$=,$/

    Anyone wants to try and beat my record?

    It's been a while. Here's an obfuscated script written over 4 years ago that finally got finished up. Though it technically works in Windows with "perl -MWin32::Console::ANSI <script>", it looks much better in Linux or MacOS (or probably Cygwin), for which it was designed, as it uses ansi escape sequences.

    Note: to change the speed give an optional delay argument in fractions of a second. The default is 0.1 (ie. 0.5 would be slower, 0.05 faster).

    die+eval(q{$|=pr int"\e[ 2J\n";$k=' |';s ,,2 220;3500731;352273 5071;16007150 74;1622713,x;y; 0-4;8| _/%;;s ;5;\e[103m;g;s,6, \e[102m,g;s;7;\e [m;g;$/=$_;$_=q| hb2Gbb 5hhDei 4dh0Bh lFbi20 1hoC4d o0CdsB bp201h vDev5d v0ChzG |;s;[1 -9];>$&;g;s;[A-I ];^$&;g;y|A-I|1- 9|;{s;^(\w)(\w); ;x?($y =-97+ord$1,$x=-9 7+ord$2):s,^0,, ?$k='/':s,^([>^] )(\d), ,?map{$c=$1,$X=1 +3*$x,$Y=$y* 2,$Z=4;$"=$/=~s; %;$k;r ;map{p rint"\ e[${\$Y ++};${ X}H$_" ;$X--if++$ Z<7}sp lit';' ,$";$k= '|';se lect$J ,$a,$p,$ARG V[0]|| .1;'^' eq$c?$y --:$x+ +}1..$ 2:last;redo }}=~y %8 \n % %dr), "\e[".

    I'm contemplating about this very little piece of Perl code. I'm already more than a little bit proud of it, but I wondered if the venerated Monks had suggestions to make it even shorter:

    print"@ARGV"=~s|.|$_=2+index'temaniowkugrdsXjyqxvpcfzlbh',lc$&;$Q= 1.45*log;$_-=1<<$Q;for($O='';--$Q>0;$_/=2){$O.=chr$_%2+45}"$O "|ger

    Try it with some text as command line arguments.

    Especially I'm curious about:

    • Is there any way to avoid initializing $O?
    • I use $Q=1.45*log to approximate the number of bits in $_. Any shorter way?
    Every comment is very much appreciated!

    Tested on both Linux and Windows, and requires the Tk module to be installed. There's a lot more I could add to the basic program, but the obfuscated version was already getting fairly large.

    Without giving too much away (and perhaps you've already guessed what it does), the arrow keys work the same as the keys 'h', 'j', 'k' and 'l'. Use ^C to quit, and try the <space> and 'n' keys too.

    Visually, there's a nice surprise when it runs (see if you can figure out the trick). I had a lot of fun getting the format "just right", and was pleased to see that "perl -MO=Deparse" didn't give anything away :-)
