User talk:Ajqnic:GeSHiHighlight/Cleaned-up-a-little-bit-version

Note: The below code has been superseded by the official version which now includes the below adjustments plus a security fix.

I cleaned the script up a little by removing support for div, commenting out the purgecache line, and adding an ID array so that it is listed in Special:Version. Thought I may as well share it, since wiki isn't paper :-) --Kingboyk 05:50, 18 December 2005 (UTC)

# GeSHiHighlight.php (confirmed working for MediaWiki 1.4 and GeSHi-1.0.7.3)
# 
# By: Andrew Nicol
# http://www.nanfo.com
# Example: http://tivoza.nanfo.com/wiki/index.php/EmuProxyZA_/_emuProxyZA.c
#
# This extention allows for the easy implementation of adding code 
# highlighting to you wiki pages, you can use it for highlighting both 
# files and code. 
#
# It is a modified version of the extention origionaly by 
#   Coffman, (www.wickle.com)           
# and the later modifications by
#   E. Rogan Creswick (aka: Largos), largos@ciscavate.org, ciscavate.org/wiki/
#
# To highlight code, select you language choice from the $langArray list below 
# and add it as follows (e.g. using php language):
#   <php>
#   $foo = 45;
#   for ( $i = 1; $i < $foo; $i++ )
#   {
#     echo "$foo<br />\n";
#     --$foo;
#   }
#   </php>
#
# To highlight an uploaded file, select you language choice from the $langArray 
# list below and add it as follows (e.g. using php language):
#   <php-file>images/b/b8/CodeExample.txt</php-file>
#
# You will need to upload GeSHi to your wiki for this extension to work, Geshi 
# is avaialbe at:
#   http://qbnz.com/highlighter/
# Once you have downloaded it, uncompress it and copy the files into a subdirectory
# named geshi in your extensions directory, you don't need to copy the doc or 
# contrib directoy (they are large an unnecessary).
#
# To activate the extension, include it from your LocalSettings.php
# with: include("extensions/GeSHiHighlight.php");
#
# This extention makes use of another one of my extentions which prevents page
# caching when desired, it is very usefull in this instance as when a using 
# highlighting on a file a cached page will show the old file without this
# extention. The purgePage extention is avvailable at:
#   http://meta.wikimedia.org/wiki/User:Ajqnic:purgePage
# To use the extention find the line below and uncomment it:
#   purgePage(); //Function in purgePage.php

/* Note: The entry for the DIV language in the language array causes problems with some <div> 
tags in the Wiki, i.e. the notice underneath the text area when editting a page. To solve 
this, go to line 64, find inside the array $langArray, the entry "div" and remove that.
