Hello,
There is a java script packer:
http://dean.edwards.name/packer/
That is used to obfuscate tables in web pages.
There was a javascript and python de-obfuscator, now I ported it to perl.
http://jsbeautifier.org/
The perl module is Packer1.pm, I added to this mail.
It has to be bound by two lines of code to Beautifier.pm:
use JavaScript::Packer1 qw/js_packer/;
and
$js_source_code = js_packer($js_source_code);
Packer1.pm must be located also in directory JavaScript.
The last test in 01-javascript-beauty.t handles the packer code.
I believe, the modification I suggested earlier, is no good.
( #$js_source_code =~ s/\\/\\\\/g; # prevent \\ -> \ tktk)
I commented it out.
Please read this:
https://stackoverflow.com/questions/16168763/preserving-backslashes-in-perl-strings
I now modified the usage description:
----------------------------------------------------------------------
=head1 FUNCTIONS
$js_source_code = <<EOF
a = 12;
{return '\\w+';}
EOF
=head2 js_beautify( $js_source_code, $opts );
beautify javascript.
-----------------------------------------------------------------------
With this I suggest the user to use the EOF mechanism to create the string.
Using the EOF mechanism or reading the javascript data from a file,
there is no need to
add backslashes to the string.
I found this out, because the packer part failed to work,
if we use additional backslashes.
Thank you in advance for adding packer to the perl javascript beautifier.
