Pod::Simple::HTML(3) 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
