Question

I have a running dokuwiki and am working with code-blocks like:

<code php>
<?php

 function addOne($testparam) {
  global $test;
  $test = $test + $testparam;
 }

?>
</code>

I now would like to highlight single lines of codes (like for example lines where something has changed).

My idea was to introduce a new Syntax-Keyword in the PHP language file php.php:

...
$language_data = array(
    'LANG_NAME' => 'PHP',
    'COMMENT_SINGLE' => array(1 => '//', 2 => '#'),
    'COMMENT_MULTI' => array('/*' => '*/'),
    'COMMENT_GESHI' => array('**' => '**'),   // new source
...
        'STYLES' => array(
            'KEYWORDS' => array(
                1 => 'color: #b1b100;',
                2 => 'color: #000000; font-weight: bold;',
                3 => 'color: #990000;',
                4 => 'color: #009900; font-weight: bold;'
                ),
            'COMMENTS' => array(
                1 => 'color: #666666; font-style: italic;',
                2 => 'color: #666666; font-style: italic;',
                3 => 'color: #0000cc; font-style: italic;',
                4 => 'color: #009933; font-style: italic;',
                'MULTI' => 'color: #666666; font-style: italic;',
                'GESHI' => 'color: #00ffff; font-weight: bold;'
                ),
...

Anyway that does not seem to have any effect.

Any idea?

DokuWiki does not use inline styles when rendering GeSHi. Instead common class names for all code languages are used and styled with a single, simple set of rules in lib/styles/screen.css.

You can add or overwrite the GeSHi styling in your conf/userstyle.css (create the file and make sure to refresh DokuWiki’s cache).
