Extension Base Class

The PHP class file of every extension must inherit from Prism_Detached_Extension_Base, which is an abstract class and provides an interface for all extensions. The general structure of the interface is:

<?php

/**
* The base class for all extensions
*/
abstract class Prism_Detached_Extension_Base
{
    /**
     * The chosen theme
     *
     * @var string
     */
    protected $theme;


    abstract public function getSortOrder ();
    abstract public function getName ();
    abstract public function getDesc ();
    public function getJavascript () { /* ... */ }
    public function getCss () { /* ... */ }
}

• (string) $theme: contains the name of the chosen theme (currently one of the following: "prism" / "prism-dark" / "prism-funky")
• (int|float) getSortOrder(): Should return a number, indicating the relative (ascending) ordering. (Some extensions need to iterate over all defined languages, they should get a higher order value than language definitions)
• (string) getName(): returns the display name of the extension
• (string) getDesc(): returns the description of the extension
• (string[]) getJavascript(): returns an array of the relative paths (relative to the extension directory) to the JavaScript files
• (string[]) getCss(): returns an array of the relative paths (relative to the extension directory) to the CSS files
