Discription

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

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...

symbols wiki uses and there excape codes

< = &lt;

> = &gt;

# = &#35;

[ = &#91;

\ = &#92;

{ = &#123;

| = &#124;

} = &#125;

~ = &#126;

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  =)
