Расширения:

Обработчики прерываний (т.н. хуки, hooks) позволяют выполнять собственный код, при возникновении определенного события (например, сохранение страницы или вход пользователя). Например, следующий фрагмент кода будет запускать вызов функции MyExtensionHooks::onPageContentSaveComplete всякий раз, когда выполняется перехват PageContentSaveComplete, передавая ему аргументы функции, специфичные для PageContentSaveComplete .

Хуки могут быть зарегистрированы путем сопоставления имени хука с обратным вызовом в файле расширения extension.json:

"Hooks": {
    "PageContentSaveComplete": "MyExtensionHooks::onPageContentSaveComplete",
    "MyCustomHook": "MyExtensionHooks::myCustomHook"
}

MediaWiki предоставляет множество хуков как это расширение функциональности программного обеспечения MediaWiki. Назначение функции (известной как обработчик хука) хуку приведет к тому, что эта функция будет вызвана в соответствующей точке основного кода MediaWiki для выполнения любых дополнительных задач, которые разработчик сочтет полезными в этот момент. Каждому хуку может быть назначено несколько обработчиков, и в этом случае он будет вызывать функции в том порядке, в котором они назначены, при этом любые изменения, внесенные одной функцией, передаются последующим функциям в цепочке.

Назначьте функции хукам в конце LocalSettings.php или в вашем собственном файле расширения в области действия файла (не в функции $wgExtensionFunctions или хуке ParserFirstCallInit ). Для расширений, если поведение функции перехвата обусловлено параметром в LocalSettings.php, перехват должен быть назначен, и функция должна завершиться досрочно, если условие не было выполнено.

Вы также можете создавать новые хуки в своем собственном расширении. Он регистрируется в extension.json так же, как если бы вы регистрировали встроенный хук MediaWiki для использования в вашем расширении. Затем вы можете запустить свой хук в своем расширении, вызвав HookContainer::run( 'HookName', [ $param1, $param2 ] );. Наконец, не забудьте добавить их к Category:Extension hooks .

Введение

Перехват запускается вызовом HookContainer::run, обычно с помощью метода в HookRunner. HookContainer найдет обработчики хуков для запуска и вызовет их с параметрами, заданными для HookContainer::run. Обработчики крючков регистрируются через extension.json .

См. также Hooks.md.

В этом примере из функции doPurge в WikiPage.php, doPurge вызывает HookRunner::onArticlePurge для запуска хука ArticlePurge , передавая $this в качестве аргумента:

$this->getHookRunner()->onArticlePurge( $this )

Ядро вызывает много хуков, но Расширения также может вызывать хуки.

Запись обработчика хуков

Обработчик хука — это функция, которую вы регистрируете, который будет вызываться всякий раз, когда запускается рассматриваемый хук.

Для расширений, зарегистрируйте свои обработчики хука в extension.json :

{
	"Hooks": {
		"EventName": [
			"MyExtensionHooks::onEventName",
			"someFunction"
		]
	}
}

Обработчики хуков также могут быть зарегистрированы через глобальный массив $wgHooks . Это чаще всего используется для конкретных настроек сайта в LocalSettings.php или в устаревших расширениях, которые предшествуют extension.json. Все нижеприведенные допустимые способы определения обработчика перехвата для хука EventName, которому передаются два параметра:

Формат	Синтаксис	Результат вызова функции.
Статическая функция	`$wgHooks['EventName'][] = 'MyExtensionHooks::onEventName';`	`MyExtensionHooks::onEventName( $param1, $param2 );`
Функция без данных	`$wgHooks['EventName'][] = 'efSomeFunction';`	`efSomeFunction( $param1, $param2 );`
Функция с данными	`$wgHooks['EventName'][] = [ 'efSomeFunction', $someData ];`	`efSomeFunction( $someData, $param1, $param2 );`
встроенная анонимная функция	$wgHooks['EventName'][] = function ( $param1, $param2 ) { // ...function body };
Только объект	`$wgHooks['EventName'][] = $object;`	`$object->onEventName( $param1, $param2 );`
Объект с методом	`$wgHooks['EventName'][] = [ $object, 'someMethod' ];`	`$object->someMethod( $param1, $param2 );`
Объект с методом и данными	`$wgHooks['EventName'][] = [ $object, 'someMethod', $someData ];`	`$object->someMethod( $someData, $param1, $param2 );`

Обратите внимание, что когда объект назначается, и вы не указываете метод, вызываемый метод - "onEventName". Например, "onArticleSave", "onUserLogin" и т.д.

Дополнительные данные полезны, если вы хотите использовать одну и ту же функцию или объект для разных целей. Например:

$wgHooks['PageContentSaveComplete'][] = [ 'efIrcNotify', 'TimStarling' ];
$wgHooks['PageContentSaveComplete'][] = [ 'efIrcNotify', 'brion' ];

Этот код приведет к тому, что efIrcNotify() будет выполняться дважды при сохранении страницы: один раз для 'TimStarling' и один раз для 'brion'.

Возвращаемые значения обработчика хука

Обработчики хука могут возвращать одно из трех возможных значений:

Версия MediaWiki:

≥ 1.23

Void hooks

A void hook does not return anything. Void hook should be the most common kind in new code (T245364).

Documentation: @return void
Usage: $hookRunner->onExample();

The interface for void hooks must include a native return type hint like : void, so that extensions that choose to implement the interface (as opposed to handling it without interface validation), benefit from static analysis and thus avoid accidentally returning something. This prevents severe bugs that are hard to catch otherwise (T173615). These hooks ignore the return value and so in isolation, a return value is simply unused, harmless, with no visible effect. In production, it would cancel listeners from other extensions for the same hook. Effectively undeploying only part of an extension this way can have major consequences.

Abortable hooks

Abortable hooks may return boolean false. When a non-void return value is given to an abortable hook, it skips any and all other listeners for the same hook (i.e. in other extensions), and returns false to the hook caller. This is similar to Event.stopImmediatePropagation() and Event.preventDefault() in JavaScript.

If as the author of a feature, you want to allow an extension to disallow or cancel the user action, you can provide an abortable hook for this.

Documentation: @return bool|void
Usage: if ( $hookRunner->onExample() ) { … }

It is important that abortable hooks allow a void return. The majority of hook consumers do not make use of the abortable feature, and thus should be able to type their implementation to @return void and safely avoid the need to return something, and with it benefit from having no room for mistakingly returning false.

Return values:

void (нет возвращаемого значения или null) — обработчик хука успешно сработал. (До MediaWiki 1.23 требовалось возвращать значение true.)

false - обработчик хуков выполнил всю необходимую работу или заменил обычную обработку. Это предотвратит запуск дальнейших обработчиков и в некоторых случаях укажет вызывающей функции пропустить обычную обработку.

Во многих случаях, когда расширениям разрешено отменять действие, хук предоставляет объект Status, в который можно добавить локализованную ошибку.

Версия MediaWiki:

≤ 1.40

Prior to MediaWiki 1.41, abortable hooks could return an error message as string. This was a shortcut for producing an Internal Server Error (HTTP 500) response with the returned string displayed as the fatal error. This was deprecated in MW 1.35 (Gerrit change 571297), and removed in MW 1.41 (Gerrit change 571297).

Обработка хуков в MediaWiki 1.35 и более поздних версиях

Версия MediaWiki:

≥ 1.35

MediaWiki 1.35 introduces the HookHandlers extension attribute. Это включает в себя интерфейсы для каждого хука для улучшенной статической проверки и обнаружения документации по параметрам. It also enables dependency injection by introducing an intermediary class instance that accepts a number of specified services (instead of static callbacks that explicitly access services from global state).

The approach from MediaWiki 1.34 and earlier, of registering hook handlers directly as static methods, remains supported and is not deprecated. Extension authors may opt-in to the new system are welcome to do so. To learn more, see the MediaWiki core: Hook specification and the announcement on wikitech-l.

Изменения в названиях хуков

Prior to MediaWiki 1.35, hooks sometimes included characters that could not be used in a class or method name, such as colons and dashes. With the introduction of per-hook interfaces, the canonical names of these hooks have been changed to use underscores instead. For example, the interface for ApiFeedContributions::feedItem is ApiFeedContributions__feedItemHook. Hook handlers that are registered with the old names remain supported.

Registering hooks using HookHandlers

To adopt the new system, change your Hooks class to have regular methods instead of static methods and to be constructible. This class is then registered once, via the HookHandlers attribute in extension.json , using the class option as part of an ObjectFactory description where you can use the services option.

Например, чтобы зарегистрировать хук BeforePageDisplay:

{
    "HookHandlers": {
        "main": {
            "class": "MediaWiki\\Extension\\Example\\Hooks",
            "services": [ "UserNameUtils" ]
        }
    },
    "Hooks": {
        "BeforePageDisplay": "main"
    }
}

Обработка хуков с использованием интерфейсов

To use hook interfaces, extensions should define a Hooks class in their namespace and implement one or more hook interfaces. Hook interfaces are named with the hook name followed by the word "Hook".

namespace MediaWiki\Extension\MyExtension;

use MediaWiki\Hook\BeforePageDisplayHook;
use OutputPage;
use Skin;

class Hooks implements BeforePageDisplayHook {
    public function onBeforePageDisplay( $out, $skin ): void { ... }
}

Convert an extension to the new hook system

Follow these steps for each hook handling method:

identify the hook handler interface, and make the Hooks class implement this interface.
update the method name and signature to be exactly the same as in the interface.
change the Hooks section of extension.json to refer to the handler you specified in the HookHandlers section.

Документация

В настоящее время хуки в ядре MediaWiki должны быть задокументированы как в [интерфейс хука https://doc.wikimedia.org/mediawiki-core/master/php/group__Hooks.html] (в репозитории исходного кода), так и в здесь на MediaWiki.org . В некоторых случаях один из этих шагов, возможно, еще не завершен, поэтому, если крючок кажется недокументированным, проверьте оба.

Каждый хук, предоставляемый ядром MediaWiki, определяется в интерфейсе хук. Как правило, интерфейсы хук расположены в подпространстве имен "Hook" внутри пространства имен вызывающего абонента. Например, Storage/Hook/PageContentSaveHook.php. Вы можете найти список интерфейсов хуков в документации MediaWiki PHP [сгенерированной https://doc.wikimedia.org/mediawiki-core/master/php/group__Hooks.html].

Чтобы задокументировать хук в вики, используйте {{MediaWikiHook }}.

По состоянию на июнь 2020 года, docs/hooks.txt устарел в качестве источника документации для отдельных хуков. Для получения дополнительной информации о внедрении хуков на основе контейнера Hook, см. [$2 спецификацию хуков в MediaWiki Core].

Шаблон документа интерфейса хука

В интерфейсах хуков комментарии doc определяют статус, назначение, параметры и поведение хука.
