Vista xeral

MediaWiki is the software that powers Wikipedia, its sister projects and thousands of wikis all over the world.

MediaWiki is written in the PHP programming language. It uses jQuery as the client JavaScript library.

MediaWiki is primarily written for the LAMP platform and runs on most operating systems. MediaWiki primarily uses the MySQL and MariaDB database servers.

MediaWiki é desenvolvido nun código abertostyle usando a linguaxe de programación PHP sobre todo para a plataforma LAMP . O desenvolvemento do núcleo é en gran parte coordinado liña.

• Development discussion happens on various mailing lists and IRC channels.

The main developer list is wikitech-l. The main developer IRC channel is #mediawiki ^connect.

• Source code is managed using the Git version control system.

• Code review for most projects is performed on Gerrit . Follow this tutorial to set up Git and Gerrit in order to submit patches.

• Bug reports and tasks for most projects are managed on Phabricator .

• Developers extending or interfacing with MediaWiki (instead of working on the core code) have several convenient extension points, including the API, the Hooks system and Skins – see the #Extending MediaWiki section of this page for an overview.

Extending MediaWiki

MediaWiki has been designed to allow for modification without changing the "core code". This makes it easy to update to a new version of MediaWiki without having to manually merge in old extension code changes. There are six main extension points that allow developers to change or extend what MediaWiki can do. The extension points are:

• API – access the data and metadata of MediaWiki instances through its web API.

• Hooks – every time a given event happens, do something.
• Parser functions – create a new command like: {{#if:...|...|...}}.
• Skins – change the look and feel of MediaWiki.
• Special pages – add a new special page.
• Tag extensions – create a new tag like: ‎<newtag>...‎</newtag>.
• Extending wiki markup – add a parser hook to modify the content of wikitext.
