PPI::HTML(3)

NAME
PPI::HTML - Generate syntax-hightlighted HTML for Perl using PPI

SYNOPSIS
  use PPI;
  use PPI::HTML;

  # Load your Perl file
  my $Document = PPI::Document->load( 'script.pl' );

  # Create a reusable syntax highlighter
  my $Highlight = PPI::HTML->new( line_numbers => 1 );

  # Spit out the HTML
  print $Highlight->html( $Document );

DESCRIPTION
PPI::HTML converts Perl documents into syntax highlighted HTML pages.

HISTORY
PPI::HTML is the successor to the now-redundant PPI::Format::HTML.

While early on it was thought that the same formatting code might be able to be used for a variety of different types of things (ANSI and HTML for example) later developments with the here-doc code and the need for independantly written serializers meant that this idea had to be discarded.

In addition, the old module only made use of the Tokenizer, and had a pretty shit API to boot.

  API Overview
The new module is much cleaner. Simply create an object with the options you want, pass PPI::Document objects to the "html" method, and you get strings of HTML that you can do whatever you want with.

METHODS

  new %args
The "new" constructor takes a simple set of key/value pairs to define the formatting options for the HTML.

page
    Is the "page" option is enabled, the generator will wrap the generated HTML fragment in a basic but complete page.

line_numbers
    At the present time, the only option available. If set to true, line numbers are added to the output.

colors | colours
    For cases where you don't want to use an external stylesheet, you can provide "colors" as a hash reference where the keys are CSS classes (generally matching the token name) and the values are colours.

    This allows basic colouring without the need for a whole stylesheet.

css The "css" option lets you provide a custom CSS::Tiny object containing any CSS you want to apply to the page (if you are using page mode).

    If both the "colors" and "css" options are used, the colour CSS entries will overwrite anything contained in the CSS::Tiny object. The object will also be cloned if it to be modified, to prevent destroying any CSS objects passed in.

Returns a new PPI::HTML object

  css
The "css" accessor returns the CSS::Tiny object originally provided to the constructor.

  html $Document | $file | \$source
The main method for the class, the "html" method takes a single PPI::Document object, or anything that can be turned into a PPI::Document via its "new" method, and returns a string of HTML formatted based on the arguments given to the "PPI::HTML" constructor.

Returns a string, or "undef" on error.
