About

This plugin is an alternative to GeSHi server-side code highlighting of DokuWiki with client-side SyntaxHighlighter by Alex Gorbatchev.

The subfolder syntaxhighlighter4/dist contains a build of SyntaxHighlighter 4.x.

For compatibility and conflicts with others plugins, please refer to the official DokuWiki SyntaxHighlighter4 plugin page.

Download and Installation

Download and install the plugin using the Plugin Manager using the download link given above. Refer to Plugins on how to install plugins manually.

If you install this plugin manually, make sure it is installed in lib/plugins/syntaxhighlighter4/. If the folder is called different it will not work!

Syntax and Usage

<sxh [brush][; options]>
... code/text ...
</sxh>

Brush

The brush (language) that SyntaxHighlighter should use. Defaults to "text" if none is provided.
See the section brushes and themes for a complete list of available brushes.

Options

Semicolon separated options for SyntaxHighlighter, see SyntaxHighlighter Configuration.
The plugin handles the Block Title from SyntaxHighlighter 3 as an option, i.e. title: <title string>;.

Defaults

Syntaxhighlighter default options can be overrided via the Config Manager :

  • autoLinks: Allows you to turn detection of links in the highlighted element on and off. If the option is turned off, URLs won’t be clickable (default true)
  • firstLine: Allows you to change the first (starting) line number (default 1)
  • gutter: Allows you to turn gutter with line numbers (default true)
  • htmlScript: Allows you to highlight a mixture of HTML/XML code and a script which is very common in web development. Setting this value to true requires that you have shBrushXml.js loaded and that the brush you are using supports this feature (default false)
  • smartTabs: Allows you to turn smart tabs feature on and off (default true)
  • tabSize: Allows you to adjust tab size (default 4)
  • override: List of tags to override

Example

<sxh php; first-line: 89; highlight: [106,107]; title: New title attribute in action>
    /**
     * Render xhtml output or metadata
     *
     * @param string         $mode      Renderer mode (supported modes: xhtml)
     * @param Doku_Renderer  $renderer  The renderer
     * @param array          $data      The data from the handler() function
     * @return bool If rendering was successful.
     */
    public function render($mode, Doku_Renderer &$renderer, $data) {
        if($mode != 'xhtml') return false;

        if (count($data) != 3) {
            return true;
        }

        list($syntax, $attr, $content) = $data;
        if ($syntax == 'sxh') {
            $title = $this->procTitle($attr);
            $highlight = $this->procHighlight($attr);
            $renderer->doc .= '<pre class="brush: ' . strtolower($attr . $highlight) . '"' . $title . '>' . $renderer->_xmlEntities($content) . '</pre>';
        } else {
            $renderer->file($content);
        }

        return true;
    }
</sxh>

     *
     * @param Doku_Event $event  event object by reference
     * @param mixed      $param  [the parameters passed as fifth argument to register_hook() when this
     *                           handler was registered]
     * @return void
     */

    public function handle_metaheader(Doku_Event &$event, $param) {
        // Add SyntaxHighlighter theme.
        $event->data['link'][] = array('rel' => 'stylesheet',
            'type' => 'text/css',
            'href' => DOKU_BASE . 'lib/plugins/syntaxhighlighter4/dist/'.$this->getConf('theme'),
        );

        // Register SyntaxHighlighter javascript.
        $event->data["script"][] = array("type" => "text/javascript",
            "src" => DOKU_BASE . "lib/plugins/syntaxhighlighter4/dist/syntaxhighlighter.js",
            "_data" => ""
        );
    }
