NAME

       Pod::Simple::HTML - convert Pod to HTML


SYNOPSIS

         perl -MPod::Simple::HTML -e Pod::Simple::HTML::go thingy.pod


DESCRIPTION

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

       This is a subclass of Pod::Simple::PullParser 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.


CALLING FROM THE COMMAND LINE

       TODO

         perl -MPod::Simple::HTML -e Pod::Simple::HTML::go Thing.pod Thing.html


CALLING FROM PERL

   Minimal code
         use Pod::Simple::HTML;
         my $p = Pod::Simple::HTML->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;

       Set the content type:

         $Pod::Simple::HTML::Content_decl =  q{<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" >};

         my $p = Pod::Simple::HTML->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 = 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 =  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 =  ' 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 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);

       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);

   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;
         use strict;
         use warnings;

         use base 'Pod::Simple::HTML';

         # 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 object and Pod::Simple::PullParserStartToken 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 = $self->SUPER::do_pod_link($link);
           return $ret;
         }

         1;

       Meanwhile in script.pl:

         use My::Pod;

         my $p = My::Pod->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
