i want to paste bbcode into tikiwiki and see how it will look like.
i searched a lot so far, but found no info how to enable bbcode as input format.
but it seems that there is some logic around for that.
while searching i found:
http://www.ipbwiki.com/Ipb_2.1:Using_BBCode_Parser
Class that parses BBCodes for PHP:

update:
i cloned wikiplugin_code.php to wikiplugin_bbcode.php and will try to implement the class.
