How to become a MediaWiki hacker/el

Αυτό το άρθρο έχει γραφεί για να βοηθήσει αρχάριους προγραμματιστές να αποκτήσουν τις απαραίτητες δεξιότητες για να συνεισφέρουν στην ανάπτυξη του MediaWiki. Note that in most cases when working with MediaWiki, you do not want to hack MediaWiki core unless you really know what you're doing.

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.

Επισκόπηση
Το MediaWiki είναι το λογισμικό που ενδυναμώνει τη Βικιπαίδεια, τα αδελφικά εγχειρήματά της και χιλιάδες wiki σε όλο τον κόσμο.

Although MediaWiki is written in the PHP programming language, some supporting tools are written in other languages, including batch files, shell scripts, makefiles and Python. 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 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.

The main developer list is wikitech-l. The main developer IRC channels are and. Follow this tutorial to set up Git and Gerrit in order to submit patches.
 * Development discussion happens on various mailing lists and IRC channels.
 * Source code is stored on and managed using the Git revision control system and can be viewed here
 * Code review is performed on and can be viewed here.
 * Bug reports are filed and projects are coordinated on and can be viewed here

Αυτή η σελίδα θα σας βοηθήσει να κάνετε τα πρώτα σας βήματα στη συνεισφορά σας στο MediaWiki. Το παρόν δεν είναι οδηγός εκμάθησης• απλώς σας στέλνει σε διάφορα σημεία όπου μπορείτε να μάθετε οτιδήποτε είναι απαραίτητο.

Set up your development environment
Πρώτα απ' όλα, ολοκληρώστε την $dev και τον οδηγό εκμάθησης του Gerrit για να κατεβάσετε τον κώδικά μας, να τον δοκιμάσετε και να αρχίσετε να υποβάλλετε τμήματα κώδικα. Then you can move on to downloading our code, making changes, testing them, and submitting patches. Υπάρχουν δύο τρόποι για να στήσεις το περιβάλλον εργασίας σου: χρησιμοποιώντας μια ήδη παραμετροποιημένη εγκατάσταση μέσω εικονικής μηχανής (vagrant), ή χειροκίνητα.

Docker development environment
This is the recommended method.
 * MediaWiki Docker – Run MediaWiki using Docker (can be used on Linux, Windows, or macOS hosts).

You can also try the experimental mwcli tool which provides basic orchestration functionality for MediaWiki docker containers. 

Εικονική μηχανή με Vagrant

 * Εγκατάσταση Vagrant - Τα βήματα αυτά θα εγκαταστήσουν το MediaWiki server με όλες τις απαιτήσεις μέσα από μια εικονική μηχανή Linux (μπορεί να χρησιμοποιηθεί σε Linux, Windows, or Mac hosts)

Vagrant is a powerful tool, but it is more complex and less robust than Docker, and significantly more resource-intensive. It is mainly aimed at developers who need to set up complex, flexible environments, e.g. for testing the interaction of multiple extensions.



Χειροκίνητη εγκατάσταση

 * Απαιτήσεις εγκατάστασης — Έλεγχος απαιτήσεων υλικού, και εγκατάσταση του LAMP, MAMP ή WAMP server (Linux, Mac ή Windows, συν Apache, MySQL και PHP).
 * — Λήψη του πιο πρόσφατου πηγαίου κώδικα από το Git.
 * — Συνέχεια με την εγκατάσταση και την αρχική παραμετροποίηση
 * Set up the various debug modes in your environment to display warning and errors early.

Δεν είναι απαραίτητο να κατεβάσετε database dumps της Wikipedia για να αναπτύξετε τα χαρακτηριστικά του Mediawiki. In fact, in many cases it's easier to use a near-empty database with a few specially-crafted test pages. Εντούτοις, αν για κάποιον λόγο θα ήθελες να έχεις ένα αντίγραφο της Wikipedia, μπορείς να κατεβάσεις ένα dump.

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


 * Learn PHP
 * PHP tutorial — Available in many different languages. If you have no knowledge of PHP but know how to program in other object-oriented programming languages, PHP will be easy for you to learn.
 * PHP Programming at Wikibooks.
 * PHP at Wikiversity.


 * PHP resources :
 * The PHP manual — Available in many different languages.
 * 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

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


 * Learn MySQL/MariaDB
 * MySQL tutorial — From the MySQL reference manual.
 * MySQL at Wikibooks.


 * MySQL/MariaDB resources
 * MySQL Reference Manuals — Available in many different languages.
 * MariaDB Knowledge Base
 * Database coding conventions within the MediaWiki community.


 * Stuff to know :
 * 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.

JavaScript and 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.


 * Learn JavaScript and CSS
 * JavaScript and CSS at Wikibooks.
 * Getting Started with jQuery — A jQuery tutorial.
 * Learning JavaScript — references and sources.


 * JavaScript and CSS resources
 * JavaScript coding conventions within the MediaWiki community.
 * CSS coding conventions within the MediaWiki community.

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.


 * MediaWiki basics and must-reads :
 *  — A high-level overview of the main components of MediaWiki and how they work with each other.
 *  — An overview of why and how to write secure code.


 * MediaWiki resources :
 * — A list of important files and links to more detailed information.
 * — A list of hooks. If you're trying to find what part of the codebase does something, often a good place to start is by searching for the related hooks.
 * — An overview of general coding conventions within the MediaWiki community.


 * Code documentation ( class reference ) — Automatically generated documentation from the code and code comments.
 * — A guide to debugging MediaWiki.
 * — A tool to interact with MediaWiki objects live.
