The WikiLambda extension provides for a wiki to host functions written, managed, and evaluated by users, which is used to power wikifunctions.org. It forms the core of the "Wikifunctions" software stack, as part of the work towards Abstract Wikipedia. The system is currently in active development, with the front-end written in Vue.js and using the new Codex interface library. Wikifunctions via WikiLambda will later provide Wikimedia wikis with a wikitext parser function to make evaluations from Wikifunctions on their local wiki.


The current working top-level architectural model for how Wikifunctions will work

Wikifunctions is a MediaWiki installation on which function content, but not output, is stored. This content takes the form of programmatic descriptions of each available function ("Functions"), actual user-written code for these functions ("Implementations"), test suites for these functions ("Testers"), and human-facing documentation about these functions, alongside the usual wiki community management content like village pumps, discussion areas, and policy pages.

Requests for function calls can come in directly via a Web request, or via MediaWiki (probably through a parser function like {{#wikifunction:…}}, but this is not yet decided). The function orchestrator determines the specifics of the request, checks the cache to see if the output value has been recently provided, and either returns that or proceeds to trigger an evaluation. To do that, it fetches all relevant content from the cluster, be that published function content (or mid-edit as-yet-unpublished function content being "previewed") from Wikifunctions, or structured content on which functions can operate from Wikidata and Wikimedia Commons. The complete bundle of code to execute and inputs on which to execute are then passed to the appropriate function executor, which then securely tries to execute the input and returns the output (or a failure error). The orchestrator then writes the successful result to the cache and transmits it to the consumer.

The WikiLambda extension is responsible for content management of the content on the Wikifunctions wiki (like the Wikibase Repository extension), providing editing interfaces, restricting users from or warning about certain actions, and providing a reading and test execution interface, and the integration of content requests on all Wikimedia wikis (like the Wikibase Client extension). User-written code is never executed in the context of the production environment, and thus never has access to sensitive content, but is only run in isolated, disposable instances.

З чого почати


  • Завантажте і розмістіть файли в каталозі з назвою WikiLambda у вашій extensions/ папці.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone --recurse-submodules https://gerrit.wikimedia.org/r/mediawiki/extensions/WikiLambda
  • Тільки під час встановлення з git виконайте Composer для встановлення залежностей PHP, подаючи composer install --no-dev в каталозі розширень. (Див. завдання T173141 щодо можливих ускладнень.)
  • Додайте такий код унизу вашого файлу LocalSettings.php :
    wfLoadExtension( 'WikiLambda' );
  • Запустіть скрипт оновлення, який автоматично створить необхідні таблиці бази даних, які потрібні цьому розширенню.
  • Yes Готово – Перейдіть до Special:Version вашої вікі, щоб переконатися, що розширення встановлено успішно.

Installing the back-end services

If you wish you install the back-end services to use the WikiLambda software, you must do so and configure them. Instructions are subject to change, and so only provided within the repo.
