add a code2 tag into wiki pages using some regex and the pre tag in a custom Mediawiki extension:

&;lt; = <

&;gt; = >

# = #

&;#91; = [

&;#92; = \

{ = {

| = |

} = }

~ = ~

its for displaying code and such like below, but with out the messing about we need to replace out any code that wiki might process...

this is a first untestedversion with just monkey knolage of how to make it work

Syntax

<code2>text</code2>

Example

<code2>some code including &;lt;b&;gt; html&;lt;/b&;gt; tags and such things... </code2>

example Result

just the code form above displayed instead of "run" ie the &;lt;b&;gt; bit isnt in bold  =)
