Bug fix[edit]
There's a small bug which causes extraneous error_log output, at least with PHP 5.1.6 and MW1.12. It's fixed with the following patch: --otheus 08:31, 15 July 2008 (UTC)

Questions[edit]
Does specifying a site-wide default alternate syntax reset all articles to be viewed in that syntax? I.e. if we already have a bunch of pages in the standard mediawiki syntax, will setting the site-wide default change these pages over to the new default? — Preceding unsigned comment added by 216.161.249.75 (talk • contribs) 16:56, 18 August 2009 (UTC)
MediaWiki 1.19.1 Compatibility[edit]
The extension does not work out-of-the-box for MW 1.19.1, but it turns out just a few changes are necessary.
This is in addition to the fact that classTextile is not included in the plugin code AND the fact that the original textile parser mentioned in the code is no longer accessible.
Anyway, download the AlternateSyntaxParser.php and classTextile.php. Name classTextile.php textile.php (or change the include line in the AlternateSyntaxParser.php).
Of course, I only tested textile having had to convert from Redmine.
Note that redmine supports an URL syntax classTextile.php doesn't handle (plain http://... form). You need to specify url at least as "$":http://... in order for this plugin to recognize it.

Wikidot syntax?[edit]
I'm wondering if this extension could be used to change a MediaWiki's syntax to Wikidot syntax. Since Wikidot's open source project is essentially obsolete and utterly dead, I've been trying to find a way to host a wiki environment that would support Wikidot's syntax so that my users don't have to learn new markup and so I have a place to fully backup my own Wikidot sites. Has anyone done this, or would anyone have an idea as to how it could be done? Should I go through the effort of writing the markup myself? NotGaryStu (talk) 22:02, 15 January 2013 (UTC)
Fix apr. 2013, MW 1.20 - v 0.1p1[edit]
Here is my patched version, with commented stuff in respect to original version, so that the patches so far on the talk page are implemented, unnecesarry calls are removed, the new wfMessage is used, there is additional hook for previewing - and also the new way of using the Markdown library is shown.

* AlternateSyntaxParser.php - Conditionally replaces wikitext processing with a alternate syntaxes.
* mod 2013, tested w/ MW 1.20 and contemporary Markdown (lib) file
* @author Jim R. Wilson / mod Smd (sdaau)
* @version 0.1p1
* @copyright Copyright (C) 2007 Jim R. Wilson
* @license The MIT License - http://www.opensource.org/licenses/mit-license.php
* -----------------------------------------------------------------------
* Description:
* This is a MediaWiki (http://www.mediawiki.org/) extension which conditionally replaces
* the wikitext parsing engine in MediaWiki with an alternate syntax parser of your
* choice. Several alternate light markup languages are supported out-of-the-box,
* and the extension is itself extensible to work with other syntaxes.
* Requirements:
* Mediawiki 1.6.x, 1.9.x, 1.10.x or higher
* PHP 4.x, 5.x or higher
* PHP Markdown or PHP Markdown Extra library:
* http://www.michelf.com/projects/php-markdown/
* Installation:
* 1. Create a folder in your $IP/extensions directory called AlternateSyntaxParser.
* Note: $IP is your MediaWiki install dir.
* 2. Drop this script (AlternateSyntaxParser.php) into $IP/extensions/AlternateSyntaxParser
* 3. Enable the extension by adding this line to your LocalSettings.php:
* require_once('extensions/MarkdownSyntax.php');
* 4. Download required libraries for chosen alternate syntaxes below
* Note: If you don't configure this, it won't do anything!
* To support Markdown Syntax:
* 1. Download Michel Fortin's PHP Markdown or PHP Markdown Extra library:
* http://www.michelf.com/projects/php-markdown/
* 2. Extract the file 'markdown.php' from the downloaded archive.
* 3. Drop markdown.php into $IP/extensions/AlternateSyntaxParser/
* To support Textile Syntax:
* 1. Download Jim Riggs' TextilePHP library:
* http://jimandlissa.com/project/textilephp
* 2. Extract the file 'Textile.php' from the downloaded archive.
* 3. Drop Textile.php into $IP/extensions/AlternateSyntaxParser/
* Usage:
* To use an alternate syntax in a page, put the following at the top of the page:
* #MARKUP language
* Where 'language' is the markup language - examples include 'markdown' and 'textile'.
* Alternatively, you may specify a site-wide default alternate language by setting
* the $wgAlternateSyntaxParserLanguage variable in your LocalSettings.php. For
* examlpe, to make Markdown the default parsing syntax, you'd add:
* $wgAlternateSyntaxParserLanguage = 'markdown';
* Version Notes:
* version 0.1:
* Initial release.
