Wiki Customizations

Documentation of tweaks and customizations made to ACC Wiki that differ from a default installation of the Mediawiki Software with special emphasis on changes that are either not documented or poorly documented elsewhere and would be difficult to reproduce without significant research or experimentation.

Extensions

  • Autoincrement - A variable hook that adds an autoincrementing variable, {{AUTOINCREMENT}}.
  • CategoryTree - Displays a collapsable tree for navigating categories/subcategories/articles. See How To Use Category Trees.
  • Cite - Basic foot note functionality. See How To Make Footnotes.
  • DynamicPageList - Allows creation of a list of pages that are listed in a set of categories with various sorting options. Usage details can be found here and details of a modification that allows last edit dates to be displayed can be found here.
  • EditCount - In-line or query based enumeration of a User's edits.
  • ParserFunctions - A set of logical and arithmetic expressions.
  • ReplaceText - Site wide text find and replace, in many cases changes cannot be undone so great care must be exercised. Restricted to Bot accounts. Contact a bot owner to request a job run.
  • Variables - Limited use of variables within templates.
  • YouTubeTag - Allows embedded YouTube videos. This extension has been modified slightly to allow the width to be specified. Usage details can be found here and details of the modification can be found here.

Message and Special Pages

Backups

A full backup of the site is performed regularly that creates an offsite copy of all database tables (MySQL), image files, extensions/configuration files, and mediawiki software files. During a backup the database is locked to avoid conflicts that could be created if the wiki were edited. It is in your interest to make a personal backup of any pages that you have completed significant work on since the last backup. Go to Special:Export, in the large text box you can enter an article/page title on each line. In general it is best to leave the "Include only the current revision" box checked, especially if you are exporting more than one page. Every single edit that is made saves a complete version of the page, so a page with many edits can be very large to export. And since the page would be reverted to the last backup, most of the history would already be preserved. Importing a page requires Sysop status, so you may need provide the copy to an admin and have them upload it for you.

Recent full backups (minor page backup done weekly):

Appearance

The image that is displayed in the upper left and links to the homepage can be set as an url for $wgLogo in the LocalSettings.php file. For example: 

$wgLogo = "http://asheron.info/~asheron/images/Site_Logo_Padula.png";

You can also replace the file wiki.png with the image you wish to use (same name) located in /skins/common/images. However this file is replaced each time the mediawiki software is updated and will need to be replaced with the desired file again each time.

Sidebar

The sidebar (links on the left) can be edited at Mediawiki:Sidebar. Some options, like the links in the toolbox, are context sensitive and will change depending on the nature of each particular page.

Drop Down Navigation Menus

This mechanism takes advantage of the Mediawiki:Sitenotice message page to display a drop down menu navigation bar on all pages. The individual menu lists are on template pages and are limited to 3 deep:

The bar is placed on the right side to avoid causing the menus to pop when going to click on the commonly used page tabs (and is offset using margin to allow the drop down menu of the right-most item to not bleed off the page).

Also, because of the way sitenotice works, changes made to the menus won't appear until you log out and log back in.

Example of code placed on the sitenotice page: 

<ul id="sitenotice_nav" style="list-style-type: none; float:right; list-style-image:
 none;-moz-border-radius-topright: 1em;-moz-border-radius-topleft: 1em; 
-moz-border-radius-bottomright: 1em; -moz-border-radius-bottomleft: 1em; 
background:#f0f0f0;margin:7px 60px -2px -2px;padding:0;">
<li>Quests{{Drop Down:Quests}}</li>
<li>Patches{{Drop Down:Patches}}</li>
<li>Items{{Drop Down:Items}}</li>
<li>Locations{{Drop Down:Locations}}</li>
<li>Lore{{Drop Down:Lore}}</li>
<li>Help{{Drop Down:Help}}</li>
</ul>

The following code is placed on the Mediawiki:Common.css page: 

/* START OF DROP DOWN MENUS */
div#siteNotice {
	width:100%; 	/* makes the div full width */
	float:left; /*makes the div enclose the list */

Page Caching

The wiki employs a simple page caching method that creates an html copy of a page each time it is changed. This cached copy is retrieved when a page is requested by a visitor that is not logged in (this skips creating the page from scratch and the processing overhead that entails). Files are saved in a "cache" folder in the mediawiki install directory. This folder may need to be created manually and set with write permissions. See File cache for more details.

This is enabled by setting the following values in the LocalSettings.php file: 

$wgUseFileCache = true;
$wgFileCacheDirectory = "$IP/cache";

LocalSettings.php

Many customizations are made by altering the LocalSettings.php file located in the root directory with the mediawiki software on the server. This file can only be accessed by someone with access to the server because it contains security settings and password information.

This is a core mediawiki file and is read every time a page is rendered. Therefore changes that are not well formed php code can cause the entire site to become unavailable. If this happens you will likely see something like this:

Parse error: parse error in \~asheron\LocalSettings.php on line 225

The line number corresponds to the actual line number in the file, to aid in finding what is causing the problem.

Customized Settings

The following may not always be completely up to date, but will be useful in any event. Also note that other modifications to the LocalSettings file are detailed in other sections on this page and not repeated here. 

// Special Permissions
        $wgGroupPermissions['bot']['replacetext']       = true;

## Customizations
$wgEnableMWSuggest = true;
$wgCountCategorizedImagesAsUsed = true;
$wgUploadSizeWarning = 1024 * 150;
$wgUseAjax = true;

## This is the list of permitted extensions for uploading files.
## Uploading files with extensions not in this list will trigger 
## a warning (and not be allowed).
$wgFileExtensions = array( 'png', 'gif', 'jpg' );
