NAME
   JavaScript::Packer - Perl version of Dean Edwards' Packer.js

VERSION
   Version 2.04

DESCRIPTION
   A JavaScript Compressor

   This module is an adaptation of Dean Edwards' Packer.js.

   Additional information: http://dean.edwards.name/packer/

SYNOPSIS
       use JavaScript::Packer;

       my $packer = JavaScript::Packer->init();

       $packer->minify( $javascript, $opts );

   To return a scalar without changing the input simply use (e.g. example
   2):

       my $ret = $packer->minify( $javascript, $opts );

   For backward compatibility it is still possible to call 'minify' as a
   function:

       JavaScript::Packer::minify( $javascript, $opts );

   The first argument must be a scalarref of javascript-code.

   Second argument must be a hashref of options. Possible options are:

   compress
       Defines compression level. Possible values are 'clean', 'shrink',
       'obfuscate' and 'best'. Default value is 'clean'. 'best' uses
       'shrink' or 'obfuscate' depending on which result is shorter. This
       is recommended because especially when compressing short scripts the
       result will exceed the input if compression level is 'obfuscate'.

   copyright
       You can add a copyright notice at the top of the script.

   remove_copyright
       If there is a copyright notice in a comment it will only be removed
       if this option is set to a true value. Otherwise the first comment
       that contains the word "copyright" will be added at the top of the
       packed script. A copyright comment will be overwritten by a
       copyright notice defined with the copyright option.

   no_compress_comment
       If not set to a true value it is allowed to set a JavaScript comment
       that prevents the input being packed or defines a compression level.

           /* JavaScript::Packer _no_compress_ */
           /* JavaScript::Packer shrink */

EXAMPLES
   Example 1
       Common usage.

           #!/usr/bin/perl

           use strict;
           use warnings;

           use JavaScript::Packer;

           my $packer = JavaScript::Packer->init();

           open( UNCOMPRESSED, 'uncompressed.js' );
           open( COMPRESSED, '>compressed.js' );

           my $js = join( '', <UNCOMPRESSED> );

           $packer->minify( \$js, { compress => 'best' } );

           print COMPRESSED $js;
           close(UNCOMPRESSED);
           close(COMPRESSED);

   Example 2
       A scalar is requested by the context. The input will remain
       unchanged.

           #!/usr/bin/perl

           use strict;
           use warnings;

           use JavaScript::Packer;

           my $packer = JavaScript::Packer->init();

           open( UNCOMPRESSED, 'uncompressed.js' );
           open( COMPRESSED, '>compressed.js' );

           my $uncompressed = join( '', <UNCOMPRESSED> );

           my $compressed = $packer->minify( \$uncompressed, { compress => 'best' } );

           print COMPRESSED $compressed;
           close(UNCOMPRESSED);
           close(COMPRESSED);
