How to become a MediaWiki hacker/fa

این مقاله برای کمک به توسعه دهندگان برای یادگیری مهارت‌های اساسی مورد نیاز برای کمک به توسعه هستهٔ مدیا‌ویکی و افزونه‌های مدیا‌ویکی نوشته شده است.

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.

If you are an experienced developer who is familiar with using MediaWiki already, visit the  instead.

مدیا‌ویکی نرم‌افزاری است که به ویکی‌پدیا، پروژه‌های خواهر و هزاران ویکی در سراسر جهان قدرت می‌بخشد.

Most of MediaWiki and extensions are written in the PHP programming language. JavaScript is used for providing interactive interface elements along with jQuery and Vue.js as client JavaScript libraries.

Some supporting tools are written in other languages, including batch files, shell scripts, makefiles and Python.

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

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.

Find or create a task
Before you ever develop a feature or fix a bug in a MediaWiki project, it is important that you do your research about it. This includes:


 * 1) Search Phabricator if an open or closed Task (Document Types field) already exists. If it doesn't, create one. If this is a very small change, don't create one.
 * 2) Find and investigate the code that needs to be changed to implement the feature. Comment your findings on the Phabricator Task if they might be helpful to others who implement it or review your changes.
 * 3) Determine if you can likely add the feature or fix the bug based the code you investigated and the changes needed. If the task is large or complex, you should find something easier and work your way up to eventually be able to handle tasks of that size. If you believe you can complete it, assign yourself to the Task and begin working on it.



محیط توسعه خود را تنظیم کنید
Once you have found something you can work on, the next step to developing MediaWiki or an extension is creating an environment to run MediaWiki, its database, and any other external features so that you can develop and test them.

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

Docker

 * MediaWiki Docker – Run MediaWiki using Docker.

Docker is a good option if you want to setup a MediaWiki installation quickly and are not planning on installing many extensions.

You can also try the experimental mwcli tool which sets up Docker with a few simple commands and provides basic orchestration functionality between MediaWiki, MySQL, ElasticSearch, Memcache, and other types of containers.

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 adding extensions in a Docker or local installation, but it runs a bit slower than the other two options.



نصب دستی
MediaWiki can be developed by installing it and its dependencies locally on your system.

It will take much more time to set up than Docker or Vagrant.


 * 1)  — Check hardware requirements and install dependencies
 * 2)  — Download the latest source code from Git.
 * 3)  — Continue with the installation and initial configuration.
 * 4) Set up the various debug modes in your environment to display warning and errors early.

Open a code editor
The two recommended code editors for editing MediaWiki are VSCode and PhpStorm. VSCode is free and PhpStorm is paid, however, you can acquire a PhpStorm license for free if you are a student by linking your GitHub Education account to your JetBrains account, or by requesting a license granted to Wikimedia.

To determine which editor you should use, know that all-around, PhpStorm has more and more-powerful features than VSCode, however, you may not want to become "tied" to it and instead it may be beneficial to learn and expose yourself to the ever-growing ecosystem of VSCode and its extensions. Additionally, PhpStorm takes significantly longer to load on start than VSCode as it builds an index of the entire repository whereas VSCode progressively loads. Therefore, VSCode is typically useful for file-viewing sessions or small changes and PhpStorm for larger changes. It makes sense to have both installed for these reasons.

To develop the MediaWiki codebase that is inside a Docker container you can establish a remote connection to it and open the MediaWiki folder inside it using VSCode or PhpStorm.

Change and test the code
Change the code and view your changes by reloading your MediaWiki browser tab. Make sure to follow. Write and run tests on your code to make sure it works and is formatted properly.

Note, you can save time by ensuring your changes will be accepted before taking the time to write tests. Create a patch without needed tests and ask for someone to review it stating that you will add tests after they review it.

Create a patch
Finally, to submit your code to be reviewed and added to the repository you are contributing to, follow.



PHP
MediaWiki is written in PHP, so you'll need to get familiar with PHP to hack MediaWiki's core.

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

 * چیزهایی برای دانستن:
 * Test your code with 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.



جاوا اسکریپت و سی‌اس‌اس
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.
