my first JAPH

[jake]

My first JAPH. Hope you like...

#!/usr/bin/perl 

@rof=qw(4 13 -1 9);@rof=reverse(@rof);
$dro = 'A' ; sub Z{ eval $_[0] };$Y=';
for@rof ( (++ord$dro +_$ )rhc ) tnirp;
'; $Y; sub X { return reverse $_[0] };
$Y=~s/\(/m4vg/g;$dro;$Y =~ s/\)/\(/g ;
$rof ;$Y=~s/m4vg/\)/g;$Y=X($Y); Z($Y);

--jake

Very nice. I like the evaled reversed code, for@rof is quite cool.

I think your substitutions are a bit too decipherable.


Good:   $Y=~s/\(/m4vg/g;
Better: $Y=~s s\(sm4vgsggsi;

Good:   $Y =~ s/\)/\(/g ;
Better: $Y =~ s s\)s(sggsi ;

Good:   $Y=~s/m4vg/\)/g;
Better: $Y=~s(m4vg))\))g; 

Very commendable for a first japh though.

Thanks for the tips. I'll definately keep these in mind for now on. Here is what it looks like using your suggestions:

#!/usr/bin/perl

@rof=qw(4 13 -1 9);@rof=reverse(@rof);
$dro = 'A' ; sub Z{ eval $_[0] };$Y=';
for@rof ( (++ord$dro +_$ )rhc ) tnirp;
'; $Y; sub X { return reverse $_[0] };
$Y=~s s\(sm4vgsggsi;$Y=~s s\)s(sggsi ;
$rof;$Y=~s(m4vg))\))g;$Y=X($Y); Z($Y);

I tried a few more ideas in this last version:

#!/usr/bin/perl

;@rof=qw(4 13 -1 9);@rof=reverse(@rof);
;sub gg{eval$_[0]};$dro='A';$q=''."".';
;for@rof((++ord$dro+_$)rhc)tnirp;(q$)g;
;';$q||=$gg;sub g{return reverse$_[0]};
;$q=~s)\()\"\')g;$s||=$q;$s=~s~\)~\(~g;
;$g=$s;$g=~s^\"\'^\)^g;$g=g($g);gg($g);

And now I shall retire this obfuscation and start working on my next one...
