NAME

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

CONTENTS

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 <B>beforeB> 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
