The TextExtracts extension provides an API which allows retrieval of plain-text or limited HTML (HTML with content for some CSS classes removed) extracts of page content.

Установка

  • Скачайте и распакуйте файл(ы) в папку с названием TextExtracts в вашей папке extensions/.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TextExtracts
  • Добавьте следующий код в конце вашего файла LocalSettings.php :
    wfLoadExtension( 'TextExtracts' );
    
  • Yes Готово – Перейдите на страницу Special:Version на своей вики, чтобы удостовериться в том, что расширение успешно установлено.

Для использующих MediaWiki 1.26 или более ранние версии:

В приведенных выше инструкциях описывается новый способ установки этого расширения с использованием wfLoadExtension(). Если вам нужно установить это расширение на более ранние версии (MediaWiki 1.26 и более ранние), вместо wfLoadExtension( 'TextExtracts' );, вам необходимо использовать:

require_once "$IP/extensions/TextExtracts/TextExtracts.php";

Настройки конфигурации

  • $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.

                "extract": "Earth, also called the world and, less frequently, Gaia, (or Terra in some works of science fiction)..."

    }
}

Предостережения

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

  • 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.

ЧЗВ

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).
