Die Erweiterung TextExtracts stellt eine API zur Verfügung, die das Abrufen von Klartext- oder reduzierten HTML-Ausschnitten (HTML mit entferntem Inhalt für einige CSS-Klassen) des Seiteninhalts ermöglicht.

Installation

  • Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens TextExtracts im Ordner extensions/ ablegen.
    Entwickler und Code-Beitragende sollten stattdessen die Erweiterung von Git installieren, mit:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TextExtracts
  • Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen: 
    wfLoadExtension( 'TextExtracts' );
  • Yes Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.

Konfiguration

  • $wgExtractsRemoveClasses is an array of <tag>, <tag>.class, .<class>, #<id> which will be excluded from extraction.
  • For example, $wgExtractsRemoveClasses[] = 'dl'; removes indented text, often used for non-templated hatnotes that are not desired in summaries.
  • extension.json defines the defaults, of which the class "noexcerpt" is one - this may be added to any template to exclude it.
  • $wgExtractsExtendOpenSearchXml defines whether TextExtracts should provide its extracts to the Opensearch API module. The default is false.

        }
    }

Caveats

There are various things to be aware of when using the API or software that uses the API e.g. Erweiterung:Popups .

  • We do not recommend the usage of `exsentences`.

It does not work for HTML extracts and there are many edge cases for which it doesn't exist. For example "Arm. gen. Ing. John Smith was a soldier." will be treated as 4 sentences. We do not plan to fix this.

  • Inline images are stripped from the response (even in HTML mode). This means if you are using the Math extension and using formulae in your lead section they may not appear in the summary output.
  • In HTML mode we cannot guarantee well formed HTML. Resulting HTML may be invalid or malformed.
  • In plaintext mode:
    • citations may not be stripped (see phab:T197266)
    • if a paragraph ends with an HTML tag e.g. ref tag, new lines may be dropped (see phab:T201946)
    • new lines may be dropped after lists phab:T208132
    • Articles must begin with the lead paragraph for an extract to be generated. The use of any template, and/or unclosed or empty HTML element may result in no preview for the article. E.g. "<div></div>hello" will give an empty extract.

FAQ

How can I remove content from a page preview/extract?

TextExtracts will strip any element that is marked with the class .noexcerpt. This is provided by the $wgExtractsRemoveClasses configuration variable (which also defines some other excluded elements).
