How to become a MediaWiki hacker/es

Este artículo está escrito para ayudar a desarrolladores novatos para que aprendan las habilidades necesarias para contribuir al desarrollo de MediaWiki y sus extensiones.

The main path to get started with Wikimedia development is to contribute to Wikimedia projects that offer mentoring. An alternative without mentoring is to fix a good first bug.

Resumen
MediaWiki es el software que permite el funcionamiento de Wikipedia, sus proyectos hermanos y miles de wikis en todo el mundo.

MediaWiki está escrito en el lenguaje de programación PHP. Usa jQuery como librería cliente de JavaScript.

MediaWiki está escrito principalmente para la plataforma LAMP y se ejecuta en la mayoría de los sistemas operativos. MediaWiki usa principalmente servidores de MySQL y MariaDB.

Development happens in an open source style, is largely coordinated online, and supported by the Wikimedia Foundation, though volunteer community developers play a huge part as well.

La lista principal de desarrolladores es wikitech-l. Los canales del desarrollador son y.
 * Development discussion happens on, , and IRC channels.
 * Source code is stored on and managed using the Git revision control system and can be viewed here
 * Revisión de códigos es desarrollada en . Sigue este tutorial para instalar Git y Gerrit para enviar cambios.
 * Reportes de error y tareas se administran en y se pueden ver aquí



Instalando tu ambiente de desarrollo
You can install and develop MediaWiki on Linux, Windows, or macOS using any of the three solutions below.

La mayoría de los proyectos usan Git y Gerrit. Sigue el tutorial de Gerrit para crear tu cuenta de desarrollador. Then you can move on to downloading our code, making changes, testing them, and submitting patches. Hay dos maneras para instalar vuestro entorno de desarrollo: utilizando un pre-máquina virtual configurada setup (vagrant), o manual.

Docker

 * MediaWiki Docker – Ejecuta MediaWiki mediante Docker (puede ser usado en Windows, MacOS o Linux)

You can also try the experimental mwcli tool which sets up Docker with a few simple commands and provides basic orchestration functionality for MediaWiki Docker containers. With this you can easily add extensions and features to your container.

If you run it from Windows, Docker shares files between your Windows filesystem and the container filesystem. This can cause MediaWiki to be very slow if you are using WSL2 based engine, due to the poor performance of its shared directory implementation. If you have Windows Pro, you can switch to the Hyper-V backend in the settings of Docker Desktop for better filesystem performance.

An even faster way to run MediaWiki using Docker in Windows (speeds comparable to manually installing) is to clone MediaWiki and run Docker from WSL (or install and run  inside of WSL). That way there is no shared filesystem overhead. To develop the MediaWiki codebase that is inside the Docker container you can establish a remote connection to it and open the MediaWiki WSL folder in that is in the container using VSCode or PhpStorm.

Máquina virtual con Vagrant

 * MediaWiki Vagrant – Run MediaWiki on a Linux virtual machine using Vagrant.

Vagrant allows you start a MediaWiki instance you can develop as well as allowing you to add and develop any of 250+ extensions - all with a single command. This saves you installation and configuration time compared to manually installing. It runs faster than Docker on Windows, however slower than Docker on WSL or manually installing.



Instalación manual
MediaWiki can be developed by installing it natively on your system and editing its code. Installing it natively means it will run faster than Docker or Vagrant, but it will take more time to configure.


 * 1)  — Check hardware requirements and install dependencies
 * 2)  — Descarga el código de fuente más reciente desde Git.
 * 3)  — Continuar con la instalación y configuración inicial
 * 4) * Instalar varios modos de debug en vuestro entorno para mostrar advertencias y errores pronto.

PHP
MediaWiki está escrito en PHP, por lo que necesitarás familiarizarte con PHP para modificar el núcleo de MediaWiki.

 * PHP at Wikiversity.


 * Recursos de PHP:
 * El manual de de PHP — Disponible en muchos idiomas diferentes.
 * PHP coding conventions within the MediaWiki community.


 * Stuff to know :
 * The script  in MediaWiki provides a basic PHP interpreter with MediaWiki objects and classes loaded.
 * Also, the script  in MediaWiki is a replacement of   based on PsySH, see

Base de datos
Many features require some amount of database manipulation, so you'll often need to be familiar with MySQL/MariaDB.

 * MariaDB Knowledge Base
 * Database coding conventions within the MediaWiki community.


 * Stuff to know :
 * Prueba tu código con MySQL/MariaDB.
 * MediaWiki currently uses MySQL and MariaDB as the primary database back-end. It also supports other DBMSes, such as PostgreSQL and SQLite. However, almost all developers use MySQL/MariaDB and don't test other DBs, which consequently break on a regular basis. You're therefore advised to use MySQL/MariaDB when testing patches, unless you're specifically trying to improve support for another DB. In the latter case, make sure you're careful not to break MySQL/MariaDB (or write queries that are horribly inefficient in it), since MySQL/MariaDB is what everybody else uses.



JavaScript y CSS
JavaScript and CSS have become omnipresent in front-end code. You don't have to be familiar with JavaScript, jQuery and CSS to work on MediaWiki, but you might need to, depending on what you choose to work on.

MediaWiki
The MediaWiki code base is large and some parts are ugly; don't be overwhelmed by it. When you're first starting off, aim to write features or fix bugs which only touch a small region of code.
