[Pkg-mediawiki-devel] Bug#579080: php-geshi: Can't render Scheme code

Package: php-geshi
Severity: normal

php-geshi can't render Scheme code. It appears to have something to do
with GeSHi's disallowed characters in keywords (Scheme keywords can
include pretty much any character, including '?', '/' and '='), but my
PHP skills aren't sufficient for me to figure out exactly what's

Here's the warning I'm getting:

Apr 18 10:11:05 drewhess apache2: PHP Warning:  preg_replace_callback(): Unknown modifier 'c' in /usr/share/php-geshi/geshi.php on line 3300

Removing all of the Scheme keywords in scheme.php that include "odd"
characters such as '?', '/' and '=' fixes the problem.

If you have a MediaWiki install with the GeSHi extension installed,
you can easily test this yourself with the following markup:

<source lang="scheme">
(define x 3)

MW should render just a blank page. Change "scheme" in the markup to
just about anything else (including "lisp") and you'll see the
highlighted source code in the page.

I've also filed a bug upstream here:
