# NAME

Pod::Simple::XHTML::BlendedCode - Blends syntax-highlighted code and pod in one XHTML document.

# VERSION

This document describes Pod::Simple::XHTML::BlendedCode version 2.000

# SYNOPSIS

        use Pod::Simple::XHTML::BlendedCode 2.000 qw();

        my $parser = Pod::Simple::XHTML::BlendedCode->new();

        # These routines are specific to Pod::Simple::XHTML::BlendedCode.
        $parser->internal_modules_hash({
            'Perl::Dist::WiX(.*)?'   => 'Perl-Dist-WiX/', # Key can be a regex.
            'Perl::Dist::VanillaWiX' => 'Perl-Dist-WiX/',
            'File::List::Object'     => 'File-List-Object/',
            'Alien::WiX'             => 'Alien-WiX/',
        });
        $parser->internal_url_postfix('.pm.html');
        $parser->internal_url_prefix('http://csjewell.comyr.com/perl/');
        $parser->internal_url_divide_slashes(1);

        # Since this is a subclass of Pod::Simple::XHTML,
        # you can use all of its routines.
        $parser->index(1);
        $parser->html_css('code.css');
        $parser->parse_file('Perl-Dist-WiX\\lib\\Perl\\Dist\\WiX.pm');

# DESCRIPTION

This class is a formatter that takes Pod and Perl code and renders it as XHTML validating HTML.

This is a subclass of Pod::Simple::XHTML and inherits all its methods.

# METHODS

`Pod::Simple::XHTML::BlendedCode` offers additional methods that modify the format of the HTML output. Call these after creating the parser object, but before the call to `parse_file` or `parse_string_document`:

      my $parser = Pod::Simple::XHTML::BlendedCode->new();
      $parser->set_optional_param("value");
      $parser->parse_file($file);

## internal_modules_hash

This determines which modules are internal to your own web site.

The module names in `L<>` links are compared against the regular expressions (wrapped in `\A` and `\z`) that are contained in the keys. If no keys match, then normal link processing is used.

If a key matches, then it is considered a "site-internal" link and the value is appended to `internal_url_prefix` for this link, and `internal_url_divide_slashes` and `internal_url_postfix` are also used when creating the link.

If you are putting all modules in one path (so that there are no per-distribution prefixes), set the values to the empty string.

This defaults to an empty hashref, and a hashref must be passed in.

## internal_url_divide_slashes

If this is set to a true value, then slashes are used to divide the portions of a module name in the URL generated for an internal link.

If not, then the module name is left as is.

## internal_url_prefix

In turning an internal link to Foo::Bar into http://whatever/Foo%3a%3aBar or http://whatever/Foo/Bar, what to put before the "Foo%3a%3aBar" or "Foo/Bar". This option is not set by default.

## perldoc_url_postfix

What to put after "Foo%3a%3aBar" or "Foo/Bar" in the URL for an internal link. This option is not set by default.

## tab_to_spaces

How many spaces a tab is equivalent to. Defaults to 4.

# DIAGNOSTICS

"The parser's internal_modules_hash method is not returning a hashref" will be croaked upon processing of the first pod link when the interal_modules_hash method was passed anything but a hashref previously.

Also, this module will report any diagnostic Pod::Simple::XHTML will, as well as any diagnostic that Pod::Parser will during the blending process.

# CONFIGURATION AND ENVIRONMENT

Pod::Simple::XHTML::BlendedCode requires no configuration files or environment variables.

# DEPENDENCIES

Perl 5.8.1 is the mimimum version of perl that this module will run on.

Other modules that this module depends on are Pod::Simple::XHTML, PPI::HTML 1.08, and parent 0.223.

# INCOMPATIBILITIES
