NAME

TOBYINK::Pod::HTML - convert Pod to HTML like TOBYINK

SYNOPSIS

   #!/usr/bin/perl
   
   use strict;
   use warnings;
   use TOBYINK::Pod::HTML;
   
   my $pod2html = "TOBYINK::Pod::HTML"->new(
      pretty             => 1,       # nicely indented HTML
      code_highlighting  => 1,       # use PPI::HTML
      code_line_numbers  => undef,
      code_styles        => {        # some CSS
         comment   => 'color:green',
         keyword   => 'font-weight:bold',
      }
   );
   
   print $pod2html->file_to_html(__FILE__);

DESCRIPTION

Yet another pod2html converter.

Note that this module requires Perl 5.14, and I have no interest in supporting legacy versions of Perl.

Constructor

new(%attrs)

Moose-style constructor.

Attributes

pretty

If true, will output pretty-printed (nicely indented) HTML. This doesn't make any difference to the appearance of the HTML in a browser.

This feature requires XML::LibXML::PrettyPrint.

Defaults to false.

code_highlighting

If true, source code samples within pod will be syntax highlighted as Perl 5.

This feature requires PPI::HTML and PPI::Document.

Defaults to false.

code_line_numbers

If undef, source code samples within pod will have line numbers, but only if they begin with "#!".

If true, all source code samples within pod will have line numbers.

This feature only works in conjunction with code_highlighting.

Defaults to undef.

code_styles

A hashref of CSS styles to assign to highlighted code. The defaults are:

   +{
      symbol        => 'color:#333;background-color:#fcc',
      pod           => 'color:#060',
      comment       => 'color:#060;font-style:italic',
      operator      => 'color:#000;font-weight:bold',
      single        => 'color:#909',
      double        => 'color:#909',
      literal       => 'color:#909',
      interpolate   => 'color:#909',
      words         => 'color:#333;background-color:#ffc',
      regex         => 'color:#333;background-color:#9f9',
      match         => 'color:#333;background-color:#9f9',
      substitute    => 'color:#333;background-color:#f90',
      transliterate => 'color:#333;background-color:#f90',
      number        => 'color:#39C',
      magic         => 'color:#900;font-weight:bold',
      cast          => 'color:#f00;font-weight:bold',
      pragma        => 'color:#009',
      keyword       => 'color:#009;font-weight:bold',
      core          => 'color:#009;font-weight:bold',
      line_number   => 'color:#666',
      # for non-Perl code
      alert         => 'color:#f00;background-color:#ff0',
      warning       => 'color:#f00;background-color:#ff0;font-style:italic',
      error         => 'color:#f00;background-color:#ff0;font-style:italic;font-weight:bold',
      bstring       => '',
      function      => '',
      regionmarker  => '',
      others        => '',
   }

Which looks kind of like the Perl highlighting from SciTE.

Methods

file_to_dom($filename)

Convert pod from file to a XML::LibXML::Document object.

string_to_dom($document)

Convert pod from string to a XML::LibXML::Document object.

file_to_xhtml($filename)

Convert pod from file to an XHTML string.

string_to_xhtml($document)

Convert pod from string to an XHTML string.

file_to_html($filename)

Convert pod from file to an HTML5 string.

This feature requires HTML::HTML5::Writer.

string_to_html($document)

Convert pod from string to an HTML5 string.

This feature requires HTML::HTML5::Writer.

Alternative Syntax Highlighting

This module defines an additional Pod command to change the language for syntax highlighting. To tell TOBYINK::Pod::HTML to switch to, say, Haskell instead of the default (Perl), just use:

   =for highlighter language=Haskell

Then all subsequent code samples will be highlighted as Haskell, until another such command is seen.

While syntax highlighting for Perl uses PPI::HTML, syntax highlighting for other languages uses either Syntax::Highlight::RDF or Syntax::Highlight::Engine::Kate as appropriate, so you need to have them installed if you want this feature.

Note that the language names defined by Syntax::Highlight::Engine::Kate are case-sensitive, and TOBYINK::Pod::HTML makes no attempt at case-folding, so you must use the correct case!

Note that only the PPI highlighter supports line numbering.

The following command can be used to switch to plain text syntax highlighting (i.e. no highlighting at all):

   =for highlighter language=Text
