Pod::Simple::HTML(3pm) Perl Programmers Reference Guide Pod::Simple::HTML(3pm) 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 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 SEE ALSO Pod::Simple, Pod::Simple::HTMLBatch TODO: a corpus of sample Pod input and HTML output?
