Syntax Highlighting for Wordpress: What works best for me

I tried several systems for Syntax Highlighting in Wordpress. The two most interesting Systems are dp.SyntaxHighlighter and iG:Syntax Hiliter.

The dp.SyntaxHighlighter looks very nice and its handling is quite good. There is only on critical factor, which makes it unusable for Wordpress Users: The Code inside the Textarea will be reformatted by Wordpress by inserting additional <p> and <br /> Tags. So I went over to iG:Syntax Hiliter.

The iG:Syntax Hiliter looks good as well and has a very nice Wordpress implementation. You just have to surround you code with the appropriate Wordpress-Style Tags. e.g.:

[as]trace(”hello world”);[/as]

gives

PLAIN TEXT
Actionscript:

  1. trace(“hello world”);

That’s it, easy and powerfull. The only problem I ran into was when displaying HTML Syntax including Hyperlinks, the iG:Syntax Hiliter Engine conflicts with displayed HTML Code because of its function to link Sourcecode Keywords to their appropriate Reference (e.g.: the <ul> will automatically be linked to http://december.com/html/4/element/ul.html). The Result was some spaghetticode wich did not validate. As I don’t really like the Reference linking Feature of iG:Syntax Hiliter I just took the geshi.php file and commented the part out which does the job:

PLAIN TEXT
PHP:

  1. function add_url_to_keyword ($keyword, $group, $start_or_end)
  2. {
  3.     /*if (isset($this->language_data[’URLS’][$group]) &&
  4.         $this->language_data[’URLS’][$group] != ” &&
  5.         substr($keyword, 0, 5) != ‘&lt;/’) {
  6.         // There is a base group for this keyword
  7.         if ($start_or_end == ‘BEGIN’) {
  8.             // HTML workaround… not good form ™ but should work for 1.0.X
  9.             if ($keyword != ”) {
  10.                 // Old system: strtolower
  11.                 //$keyword = ( $this->language_data[’CASE_SENSITIVE’][$group] ) ? $keyword : strtolower($keyword);
  12.                 // New system: get keyword from language file to get correct case
  13.                 foreach ($this->language_data[’KEYWORDS’][$group] as $word) {
  14.                     if (strtolower($word) == strtolower($keyword)) {
  15.                         break;
  16.                     }
  17.                 }
  18.                 $word = ( substr($word, 0, 4) == ‘&lt;’ ) ? substr($word, 4) : $word;
  19.                 $word = ( substr($word, -4) == ‘&gt;’ ) ? substr($word, 0, strlen($word) - 4) : $word;
  20.                 if (!$word) return ”;
  21.                
  22.                 return ‘<|UR1|"’ .
  23.                     str_replace(
  24.                         array(’{FNAME}’, ‘.’),
  25.                         array(@htmlspecialchars($word, ENT_COMPAT, $this->encoding), ‘<dot>’),
  26.                         $this->language_data[’URLS’][$group]
  27.                     ) . ‘">’;
  28.             }
  29.             return ”;
  30.         // HTML fix. Again, dirty hackage…
  31.         } elseif (!($this->language == ‘html4strict’ && ‘&gt;’ == $keyword)) {
  32.             return ”;
  33.         }
  34.     }*/
  35. }

Maybe not e very smart way, but everything works fine and I’m happy. :)

    Maybe you’d like to give the SyntaxHighlighter for WordPress a try?

    It’s built on the dp.SyntaxHighlighter mentioned above, but takes care of all those linebreaks and paragraph inserted by WordPress. Not to mention the nifty administration-options. g ;-)
