pod::simple::html

Pod::Simple::HTML(3)					User Contributed Perl Documentation				      Pod::Simple::HTML(3)

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': $!
";
	 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">
};

       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 ebedded 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>');

   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[
<!-- end doc -->

</body></html>
] );

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
