Extension:Configurator

The Configurator extension reads the LocalSettings.php file and displays a form on a custom special page where the user can modify configuration variables that have previously been defined in the file. It only shows MediaWiki variables defined in LocalSettings.php that appear on their own line and have values that are a "string", int, bool, CONSTANT, or $variable. It excludes passwords. When the user submits the form, the extension backs up the current LocalSettings.php file and writes a new one.

It also has some support for extensions but the enabling/disabling stuff doesn't work yet.

Usage

 * 1) Log in as a user with the 'siteadmin' permission.
 * 2) Browse to Special Pages -> Configurator.
 * 3) Add/Modify values.
 * 4) Click Submit.
