Pod::Simple::XHTML(3) Perl Programmers Reference Guide Pod::Simple::XHTML(3)NAMEPod::Simple::XHTML-- format Pod as validating XHTML
SYNOPSIS
use Pod::Simple::XHTML;
my $parser = Pod::Simple::XHTML->new();
...
$parser->parse_file('path/to/file.pod');
DESCRIPTION
This class is a formatter that takes Pod and renders it as XHTML
validating HTML.
This is a subclass of Pod::Simple::Methody and inherits all its
methods. The implementation is entirely different than
Pod::Simple::HTML, but it largely preserves the same interface.
METHODSPod::Simple::XHTML offers a number of methods that modify the format of
the HTML output. Call these after creating the parser object, but
before the call to "parse_file":
my $parser = Pod::PseudoPod::HTML->new();
$parser->set_optional_param("value");
$parser->parse_file($file);
perldoc_url_prefix
In turning Foo::Bar into http://whatever/Foo%3a%3aBar, what to put
before the "Foo%3a%3aBar". The default value is
"http://search.cpan.org/perldoc?".
perldoc_url_postfix
What to put after "Foo%3a%3aBar" in the URL. This option is not set by
default.
title_prefix, title_postfix
What to put before and after the title in the head. The values should
already be &-escaped.
html_css
$parser->html_css('path/to/style.css');
The URL or relative path of a CSS file to include. This option is not
set by default.
html_javascript
The URL or relative path of a JavaScript file to pull in. This option
is not set by default.
html_doctype
A document type tag for the file. This option is not set by default.
html_header_tags
Additional arbitrary HTML tags for the header of the document. The
default value is just a content type header tag:
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
Add additional meta tags here, or blocks of inline CSS or JavaScript
(wrapped in the appropriate tags).
default_title
Set a default title for the page if no title can be determined from the
content. The value of this string should already be &-escaped.
force_title
Force a title for the page (don't try to determine it from the
content). The value of this string should already be &-escaped.
html_header, html_footer
Set the HTML output at the beginning and end of each file. The default
header includes a title, a doctype tag (if "html_doctype" is set), a
content tag (customized by "html_header_tags"), a tag for a CSS file
(if "html_css" is set), and a tag for a Javascript file (if
"html_javascript" is set). The default footer simply closes the "html"
and "body" tags.
The options listed above customize parts of the default header, but
setting "html_header" or "html_footer" completely overrides the built-
in header or footer. These may be useful if you want to use template
tags instead of literal HTML headers and footers or are integrating
converted POD pages in a larger website.
If you want no headers or footers output in the HTML, set these options
to the empty string.
index
TODO -- Not implemented.
Whether to add a table-of-contents at the top of each page (called an
index for the sake of tradition).
SUBCLASSING
If the standard options aren't enough, you may want to subclass
Pod::Simple::XHMTL. These are the most likely candidates for methods
you'll want to override when subclassing.
handle_text
This method handles the body of text within any element: it's the body
of a paragraph, or everything between a "=begin" tag and the
corresponding "=end" tag, or the text within an L entity, etc. You
would want to override this if you are adding a custom element type
that does more than just display formatted text. Perhaps adding a way
to generate HTML tables from an extended version of POD.
So, let's say you want add a custom element called 'foo'. In your
subclass's "new" method, after calling "SUPER::new" you'd call:
$new->accept_targets_as_text( 'foo' );
Then override the "start_for" method in the subclass to check for when
"$flags->{'target'}" is equal to 'foo' and set a flag that marks that
you're in a foo block (maybe "$self->{'in_foo'} = 1"). Then override
the "handle_text" method to check for the flag, and pass $text to your
custom subroutine to construct the HTML output for 'foo' elements,
something like:
sub handle_text {
my ($self, $text) = @_;
if ($self->{'in_foo'}) {
$self->{'scratch'} .= build_foo_html($text);
} else {
$self->{'scratch'} .= $text;
}
}
