# NAME HTML::Packer - Another HTML code cleaner <div> <a href='https://travis-ci.org/leejo/html-packer-perl?branch=master'><img src='https://travis-ci.org/leejo/html-packer-perl.svg?branch=master' alt='Build Status' /></a> <a href='https://coveralls.io/r/leejo/html-packer-perl'><img src='https://coveralls.io/repos/leejo/html-packer-perl/badge.png?branch=master' alt='Coverage Status' /></a> </div> # VERSION Version 2.11 # 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](https://metacpan.org/pod/JavaScript%3A%3APacker) 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](https://metacpan.org/pod/CSS%3A%3APacker) 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. # AUTHOR Merten Falk, `<nevesenin at cpan.org>`.
