Usage

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

  my $Highlight = PPI::HTML->new( line_numbers => 1 );
  
  # Spit out the HTML
  print $Highlight->html( $Document );

Overview

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

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.
