## NAME
    [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown) - convert Pod to HTML

## SYNOPSIS
      perl -[MPod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/MPod%3A%3ASimple%3A%3AHTML/markdown) -e [Pod::Simple::HTML::go](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3Ago/markdown) thingy.pod

## DESCRIPTION
    This class is for making an HTML rendering of a Pod document.

    This is a subclass of [Pod::Simple::PullParser](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3APullParser/markdown) and inherits all its
    methods (and options).

    Note that if you want to do a batch conversion of a lot of Pod documents
    to HTML, you should see the module [Pod::Simple::HTMLBatch](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTMLBatch/markdown).

## CALLING FROM THE COMMAND LINE
    TODO

      perl -[MPod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/MPod%3A%3ASimple%3A%3AHTML/markdown) -e [Pod::Simple::HTML::go](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3Ago/markdown) Thing.pod Thing.html

## CALLING FROM PERL
### Minimal code
      use [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown);
      my $p = [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown)->new;
      $p->output_string(\my $html);
      $p->parse_file('path/to/Module/Name.pm');
      open my $out, '>', 'out.html' or die "Cannot open 'out.html': $!\n";
      print $out $html;

### More detailed example
      use [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown);

    Set the content type:

      $[Pod::Simple::HTML::Content_decl](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3AContentdecl/markdown) =  q{<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" >};

      my $p = [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown)->new;

    Include a single javascript source:

      $p->html_javascript('<http://abc.com/a.js>');

    Or insert multiple javascript source in the header (or for that matter
    include anything, thought this is not recommended)

      $p->html_javascript('
          <script type="text/javascript" src="<http://abc.com/b.js>"></script>
          <script type="text/javascript" src="<http://abc.com/c.js>"></script>');

    Include a single css source in the header:

      $p->html_css('/style.css');

    or insert multiple css sources:

      $p->html_css('
          <link rel="stylesheet" type="text/css" title="pod_stylesheet" href="<http://remote.server.com/jquery.css>">
          <link rel="stylesheet" type="text/css" title="pod_stylesheet" href="/style.css">');

    Tell the parser where should the output go. In this case it will be
    placed in the $html variable:

      my $html;
      $p->output_string(\$html);

    Parse and process a file with pod in it:

      $p->parse_file('path/to/Module/Name.pm');

## METHODS
    TODO all (most?) accessorized methods

    The following variables need to be set before the call to the ->new
    constructor.

    Set the string that is included before the opening <html> tag:

      $[Pod::Simple::HTML::Doctype_decl](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3ADoctypedecl/markdown) = qq{<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
             "<http://www.w3.org/TR/html4/loose.dtd>">\n};

    Set the content-type in the HTML head: (defaults to ISO-8859-1)

      $[Pod::Simple::HTML::Content_decl](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3AContentdecl/markdown) =  q{<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" >};

    Set the value that will be embedded in the opening tags of F, C tags and
    verbatim text. F maps to <em>, C maps to <code>, Verbatim text maps to
    <pre> (Computerese defaults to "")

      $[Pod::Simple::HTML::Computerese](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML%3A%3AComputerese/markdown) =  ' class="some_class_name';

  html_css
  html_javascript
  title_prefix
  title_postfix
  html_header_before_title
    This includes everything before the <title> opening tag including the
    Document type and including the opening <title> tag. The following call
    will set it to be a simple HTML file:

      $p->html_header_before_title('<html><head><title>');

  top_anchor
    By default [Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown) adds a dummy anchor at the top of the HTML.
    You can change it by calling

      $p->top_anchor('<a name="zz" >');

  html_h_level
    Normally =head1 will become <h1>, =head2 will become <h2> etc. Using the
    html_h_level method will change these levels setting the h level of
    =head1 tags:

      $p->[html_h_level(3)](https://www.chedong.com/phpMan.php/man/htmlhlevel/3/markdown);

    Will make sure that =head1 will become <h3> and =head2 will become <h4>
    etc...

  index
    Set it to some true value if you want to have an index (in reality a
    table of contents) to be added at the top of the generated HTML.

      $p->[index(1)](https://www.chedong.com/phpMan.php/man/index/1/markdown);

  html_header_after_title
    Includes the closing tag of </title> and through the rest of the head
    till the opening of the body

      $p->html_header_after_title('</title>...</head><body id="my_id">');

  html_footer
    The very end of the document:

      $p->html_footer( qq[\n<!-- end doc -->\n\n</body></html>\n] );

## SUBCLASSING
    Can use any of the methods described above but for further customization
    one needs to override some of the methods:

      package [My::Pod](https://www.chedong.com/phpMan.php/perldoc/My%3A%3APod/markdown);
      use strict;
      use warnings;

      use base '[Pod::Simple::HTML](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3AHTML/markdown)';

      # needs to return a URL string such
      # <http://some.other.com/page.html>
      # #anchor_in_the_same_file
      # /internal/ref.html
      sub do_pod_link {
        # [My::Pod](https://www.chedong.com/phpMan.php/perldoc/My%3A%3APod/markdown) object and [Pod::Simple::PullParserStartToken](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3ASimple%3A%3APullParserStartToken/markdown) object
        my ($self, $link) = @_;

        say $link->tagname;          # will be L for links
        say $link->attr('to');       #
        say $link->attr('type');     # will be 'pod' always
        say $link->attr('section');

        # Links local to our web site
        if ($link->tagname eq 'L' and $link->attr('type') eq 'pod') {
          my $to = $link->attr('to');
          if ($to =~ /^Padre::/) {
              $to =~ s{::}{/}g;
              return "/docs/Padre/$to.html";
          }
        }

        # all other links are generated by the parent class
        my $ret = $self->[SUPER::do_pod_link](https://www.chedong.com/phpMan.php/perldoc/SUPER%3A%3Adopodlink/markdown)($link);
        return $ret;
      }

      1;

    Meanwhile in script.pl:

      use [My::Pod](https://www.chedong.com/phpMan.php/perldoc/My%3A%3APod/markdown);

      my $p = [My::Pod](https://www.chedong.com/phpMan.php/perldoc/My%3A%3APod/markdown)->new;

      my $html;
      $p->output_string(\$html);
      $p->parse_file('path/to/Module/Name.pm');
      open my $out, '>', 'out.html' or die;
      print $out $html;

    TODO

    maybe override do_beginning do_end
