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.

はじめに

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 To do that, it fetches all relevant content from the cluster, be that published function content (or mid-edit as-yet-unpublished function content being "previewed") from Wikifunctions, or structured content on which functions can operate from Wikidata and Wikimedia Commons.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.

始めてみよう

インストール

  • ダウンロードして、ファイルをextensions/フォルダー内のWikiLambdaという名前のディレクトリ内に配置します。
    開発者とコード寄稿者は、上記の代わりに以下を使用してGitからインストールします:
    cd extensions/
    git clone --recurse-submodules https://gerrit.wikimedia.org/r/mediawiki/extensions/WikiLambda
    
  • Gitでのインストールの場合のみ、PHPの依存関係をインストールするためComposerを実行します。 (合併症の可能性についてはT173141を参照。)
  • 以下のコードを LocalSettings.php ファイルの末尾に追加します:
    wfLoadExtension( 'WikiLambda' );
    
  • 更新スクリプトを実行します。このスクリプトは、この拡張機能が必要とするデータベーステーブルを自動的に作成します。
  • Yes 完了 – ウィキの「Special:Version」に移動して、拡張機能が正しくインストールされたことを確認します。

バックエンドサービスのインストール

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.
