NAME
Pod::Simple::HTML - convert Pod to HTML
SYNOPSIS
perl -MPod::Simple::HTML -e Pod::Simple::HTML::go thingy.podDESCRIPTION
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.htmlCALLING 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 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:
$p->html_footer( qq[\n<!-- end doc -->\n\n</body></html>\n] );SUBCLASSING
Can use any of the methods described above but for further customization one needs to override some of the methods:
package My::Pod;
use strict;
use warnings;
use base 'Pod::Simple::HTML';
# needs to return a URL string such
# http://some.other.com/page.html
# #anchor_in_the_same_file
# /internal/ref.html
sub do_pod_link {
# My::Pod object and Pod::Simple::PullParserStartToken object
my ($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
