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);
