Question about code on SU-forum
-
Hello,
I have a question about adding lines of code to my posts. Most of the times it looks like this:
Example Codeall green
But some people on the forum post code in a topic-message with the syntax highlighted.
How does this work?Tnanks a lot !
-
use
[`` code=php`` ]instead
Unfortunately we do not have a ruby syntax highlighter plugin but the php works, too (somewhat).Here is Weld.rb as an example:

Hi Gaieus,
Thanx, it can be so simple! I checked your website, nice website!

This one?
http://gaieus.hu/hehe. Thanks. Nice but first of all, simple! Does not need too much maintenance. Maybe a gallery would spice it up though...
