After i first posted code for highlight-range i made some small changes to the code in the post as i found better ways of doing things. When i inserted new lines it messed with my highlighting. Inspired by pastebin.com, i wrote a couple of lines that let me specify with a marker in the code (and not by line-number) what line should be highlighted.

Update: Added @hr@ for inline-ranges.

The second codeblock is inside a shortcode similar to this:

1

All the highlighting is done by @hr@-tags on line 740 and 761. Lines 747, 751 and 754 are prefixed with @h@ to show that single lines inside a (possibly) large highlighted range can be excluded. Both marker tags are removed and do not appear when displayed or in code-view.

        // Automatically enable "htmlscript" for certain brushes
        //if ( false === $atts['html-script'] && in_array( $lang, apply_filters( 'syntaxhighlighter_htmlscriptbrushes', array( 'php' ) ) ) )
        //  $atts['html-script'] = 'true';

@hr@        // Detect and add inline highlights (@h@) and ranges (@hr@)
        $codelines = explode("\n", $code);
        $h_marker = '@h@'; $h_marker_length = strlen($h_marker);
        $h_range = '@hr@';
        $atts['firstline'] = (int) $atts['firstline']; // sanitize firstline as we need it
        $hra = false; $h = false;
        foreach($codelines as $linenum => $line) { // could have used &$line, but that is php5-only
@h@            if($h_marker == substr($line, 0, $h_marker_length)) {
                // could have used "$line =" in php
                $codelines[$linenum] = substr($line,$h_marker_length, (strlen($line) - $h_marker_length));
                $h = true;
@h@            } else if($h_range == substr($line, 0, 4)) {
                $hra = !$hra; // we swap on/of ever time we detect the tag
                $codelines[$linenum] = substr($line,4); //, (strlen($line) - 4));
@h@            }
            if($h xor $hra) { // we use xor so we can use a @h@ to escape a active $hra
                $atts['highlight'] = ($atts['highlight'] == false) ?
                    ($linenum  + $atts['firstline'] -1 ) :
                    $atts['highlight'] . ',' . ($linenum  + $atts['firstline'] -1 );
            }
            $h = false;
        }
@hr@        $code = implode("\n",$codelines);

        // Sanitize row highlights
        if ( false != $atts['highlight'] ) {
