I'm amusing myself trying to obfuscate a little script ...

... that formats a text file for, um, legibility.

Just cat a file through it and voila! It's pretty.

#!/usr/local/bin/perl -n

@x = ( { Begin => "{", End => "}" }, "(?:Attribute|Motion|Transform|Wo
+rld|Frame)" );

$i-- if(/^\s*$x[1]End/ && $i);

/^\s*\#/?s/^\s*//:s/^\s*/" "x(4*$i)/e;
s/^(\s*$x[1](Begin|End).*)$/$1.(m|\#[\{\}]$|?"":" #$x[0]{$2}")/e;

print;

$i++ if(/^\s*$x[1]Begin/);

Any ideas? I figure that I should be able to do something that combines the two regular expression lines, then do something else to mask the data, but I'm new to the whole obfuscation thing. :^)

Thanks!

Along those lines, everything I learned about obfuscating perl code, I learned from here. And I took notes. And to make sure I could find them again, I added them to my home node. Much like some of the other regular obfuscators have. Take a gander through the pages of [id://Obfuscated Code] and check out the home nodes of some of the authors. You're likely to find a wealth of information and ideas about obfuscating code. Also, DE-obfuscating some of the higher-ranked obfuscations REALLY helps in understanding how to create jems of your own. Try a little `perl -MO=Deparse`, adding your own whitespace, etc... and you'll start to gain your own insight. --chargrill `$,=42;for(34,0,-3,9,-11,11,-17,7,-5){$.=pack'c'=>$,+=$_}for(reverse s +plit//=>$ ){$%++?$ %%2?push@C,$_,$":push@c,$_,$":(push@C,$_,$")&&push@c,$"}$C[$# +C]=$/;($#C >$#c)?($ c=\@C)&&($ C=\@c):($ c=\@c)&&($C=\@C);$%=$\|;for(@$c){print$_^ +$$C[$%++]}` [download]	[reply] [d/l] [select]
