Use

To use the syntax highlighter in wiki markup create the following:

<source>
 //[...]
</source>

Place your code where //[...] is.

Now the following parameters may be passed to the <source> tag:

• lang or language - language to use (none specified uses markup)
• data-start - the starting line number for numbering or highlight
• data-lines - the lines to highlight
• line-numbers - used as a flag to specify line numbers should be used

Example

<source lang=php data-start=29 line-numbers>
    foreach( $args as $key => $value ){
        switch ($key) {
            case 'lang':
            case 'language':
                $code_classes .= " language-$value";
                break;
            case 'class':
                $code_classes .= " $value";
                break;
            case 'line-numbers':
                $pre_args .= " class=$key";
                break;
            case 'data-start':
                $pre_args .= " data-line-offset=$value"; //should make sure this is set
            default;
                $pre_args .= " $key=$value";
        }
    }  
</source>
