Thread: [Phpwiki-talk] A PhpHighlight plugin

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi everybody!

I have a tutorial on PHP at my WikiWikiWeb, so I wrote a WikiPlugin,
that will highlight some PHP code using highlight_string(). It can be
seen in action here:

  http://www.gimpster.com/phpwiki/index.php/PhpTutorial/PrinterFriendly

(This page demonstrates a problem with the IncludePage plugin and
subpages: a relative link like /Intro on PhpTutorial is interpreted as
a relative link from PhpTutorial/PrinterFriendly when PhpTutorial is
seen through IncludePage on PhpTutorial/PrinterFriendly.)

The code for the plugin is very simple:

/**
 * A plugin that runs the highlight_string() function in PHP on it's
 * arguments to pretty-print PHP code.
 *
 * Usage:
 * <?plugin PhpHighlight
 * code that should be highlighted
 * ?>
 *
 * You should not add '<?php' and '?>' to the code - the plugin does
 * this automatically.
 *
 * Author: Martin Geisler <gim...@gi...>.

class WikiPlugin_PhpHighlight
extends WikiPlugin
{
    // Four required functions in a WikiPlugin.

    function getName () {
        return _("PhpHighlight");
    }

    function getDescription () {
        return _("PHP syntax highlighting");

    }
    // Establish default values for each of this plugin's arguments.
    function getDefaultArguments() {
        return array();
    }

    function run($dbi, $argstr, $request) {

        $str = highlight_string("<?php\n" . $argstr . "\n?>", true);
        /* Remove "<?php\n" and "\n?>": */
        $str = str_replace(array('&lt;?php<br />', '?&gt;'), '', $str);
        /* We might have made some empty font tags: */
        $search = '<font color="' . ini_get('highlight.default') . '"></font>';
        $str = str_replace($search, '', $str);

        return new RawXml($str);
    }
};
