NAME

       HTML::Packer - Another HTML code cleaner

VERSION

       Version 2.10

DESCRIPTION

       A HTML Compressor.

SYNOPSIS

           use HTML::Packer;

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

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

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

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

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

           HTML::Packer::minify( $scalarref, $opts );

       First argument must be a scalarref of HTML-Code.  Second argument must be a hashref of options. Possible
       options are

       remove_comments
           HTML-Comments will be removed if 'remove_comments' has a true value.  Comments starting with "<!--#",
           "<!--[" or "<!-- google_ad_section_" will be preserved unless 'remove_comments_aggressive' has a true
           value.

       remove_comments_aggressive
           See 'remove_comments'.

       remove_newlines
           ALL newlines will be removed if 'remove_newlines' has a true value.

       do_javascript
           Defines  compression  level  for  javascript.  Possible values are 'clean', 'obfuscate', 'shrink' and
           'best'.   Default  is  no  compression  for  javascript.   This   option   only   takes   effect   if
           JavaScript::Packer is installed.

       do_stylesheet
           Defines  compression  level  for  CSS.  Possible  values  are  'minify'  and 'pretty'.  Default is no
           compression for CSS.  This option only takes effect if CSS::Packer is installed.

       do_csp
           Defines hash algorithm for "Content-Security-Policy", or  CSP,  hashes  of  embedded  "<script>"  and
           "<style>" tags.

           Allowed values are 'sha256', 'sha384', 'sha512'.

           It  may  be left blank or set to a Perl false value to indicate that hashes should not be calculated,
           if performance is a concern.

       no_compress_comment
           If not set to a true value it is allowed to set a HTML comment that prevents the input being packed.

               <!-- HTML::Packer _no_compress_ -->

           Is not set by default.

       html5
           If set to a true value closing slashes will be removed from void elements.

       csp If "do_csp" is set to 'sha256', returns a hash that looks like this:

               (
                   'script-src' => [qw( sha256-...= sha256-...= )],
                   'style-src'  => [qw( sha256-...= sha256-...= )],
               )

           with each element of the "ARRAY"refs containing a CSP-friendly hash for  a  "<script>"  or  "<style>"
           tag.
