# HTML::Packer(3pm)

Another HTML code cleaner

## NAME

HTML::Packer - Another HTML code cleaner

## 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 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.
