This page is a translated version of the page Extension:BetaFeatures and the translation is 8% complete.

The BetaFeatures extension allows other MediaWiki extensions to register beta features with the list of user preferences on the wiki. It uses the existing user preferences architecture and a few special pages to accomplish its function.

Installation

Download and move the extracted BetaFeatures folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/BetaFeatures
Thêm mã sau vào dưới cùng tệp $LocalSettings của bạn:
```
wfLoadExtension( 'BetaFeatures' );
```

Using the new hooks in your extension

Using this extension to support your beta feature is easy. Register a hook of type GetBetaFeaturePreferences in your extension.json file — the syntax is almost identical to the GetPreferences hook, with small changes to support the type of preference we need in this case.

Trên extension.json:

    "Hooks": {
        "GetBetaFeaturePreferences": "MediaWiki\\Extension\\MyExtension\\Hooks::onGetBetaFeaturePreferences"
    },

Trên MyExtension/includes/Hooks.php:

namespace MediaWiki\Extension\MyExtension;
class Hooks {
    public static function onGetBetaFeaturePreferences( User $user, array &$betaPrefs ) {
        $extensionAssetsPath = MediaWikiServices::getInstance()
			->getMainConfig()
			->get( 'ExtensionAssetsPath' );
        $betaPrefs['myextension-awesome-feature'] = [
            // The first two are message keys
            'label-message' => 'myextension-awesome-feature-message',
            'desc-message' => 'myextension-awesome-feature-description',
            // Paths to images that represents the feature.
            // The image is usually different for ltr and rtl languages.
            // Images for specific languages can also specified using the language code.
            'screenshot' => array(
                'ru' => "$extensionAssetsPath/MyExtension/images/screenshot-ru.png",
                'ltr' => "$extensionAssetsPath/MyExtension/images/screenshot-ltr.png",
                'rtl' => "$extensionAssetsPath/MyExtension/images/screenshot-rtl.png",
            ),
            // Link to information on the feature - use subpages on mw.org, maybe?
            'info-link' => 'https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:MyExtension/MyFeature',
            // Link to discussion about the feature - talk pages might work
            'discussion-link' => 'https://www.mediawiki.org/wiki/Special:MyLanguage/Help_talk:Extension:MyExtension/MyFeature',
        ];
    }
}

For now, 'label-message', 'desc-message', 'info-link', and 'discussion-link' are required. Please be sure you use all of them!

Then, you can use the convenience function provided by BetaFeatures to check whether the feature is enabled.

// SpecialMyExtension.php
class SpecialMyExtension extends SpecialPage {

    public function execute() {
        if ( BetaFeatures::isFeatureEnabled( $this->getUser(), 'my-awesome-feature' ) ) {
            // Implement the feature!
        }
    }
}

You can also use a normal preference check, but don't check against truthy or falsy values - use the values from the HTMLFeatureField class.

// SpecialMyExtension.php
class SpecialMyExtension extends SpecialPage {

    public function execute() {
        if ( $this->getUser()->getOption( 'my-awesome-feature' ) === HTMLFeatureField::OPTION_ENABLED ) {
            // Implement the feature!
        }
    }
}

Because the BetaFeatures class should be present everywhere, you could use the convenience function in any hook, special page, or anything else you wanted. Just be aware of potential performance or caching issues you may introduce with those changes.

If you want to also use your extension without BetaFeatures, you should also check for its existence, e.g.:

if (
    !ExtensionRegistry::getInstance()->isLoaded( 'BetaFeatures' )
    || \BetaFeatures::isFeatureEnabled( $user, 'my-awesome-feature' )
) {
    // Implement the feature!
}

Configuration

The $wgBetaFeaturesWhitelist config variable can be used to limit which beta features are shown in preferences. By default it is empty, and all beta features are shown.

If it is used then in order for a beta feature to show up in the preferences it needs to be listed in the whitelist. This config variable accepts an array of strings. Each string should be the name of a beta feature as specified in the preference definition passed to onGetBetaFeaturePreferences(). For example, in the code given above, the name of the beta feature is myextension-awesome-feature, so you would need to add that string to the $wgBetaFeaturesWhitelist array in your wiki's configuration:

$wgBetaFeaturesWhitelist = [
        'myextension-awesome-feature' 
];

Advanced usage

Auto-enroll groups

With this example, we register a preference that's an "auto-enroll" one - if a user checks this, and new features come out that are in a particular group, the user will be automatically enrolled in those features.

// MyExtensionHooks.php
class MyExtensionHooks {

    static function getPreferences( $user, &$prefs ) {
        global $wgExtensionAssetsPath;

        $prefs['my-awesome-feature-auto-enroll'] = array(
            // The first two are message keys
            'label-message' => 'beta-feature-autoenroll-message',
            'desc-message' => 'beta-feature-autoenroll-description',
            // Link to information on the feature - use subpages on mw.org, maybe?
            'info-link' => 'https://wwww.mediawiki.org/wiki/Special:MyLanguage/MyFeature',
            // Link to discussion about the feature - talk pages might work
            'discussion-link' => 'https://www.mediawiki.org/wiki/Talk:MyFeature',
            // Enable auto-enroll for this group
            'auto-enrollment' => 'my-awesome-feature-group',
        );

        $prefs['my-awesome-feature'] = array(
            // The first two are message keys
            'label-message' => 'beta-feature-message',
            'desc-message' => 'beta-feature-description',
            // Paths to images that represents the feature.
            // The image is usually different for ltr and rtl languages.
            // Images for specific languages can also specified using the language code.
            'screenshot' => array(
                'ru' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-ru.png",
                'ltr' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-ltr.png",
                'rtl' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-rtl.png",
            ),
            // Link to information on the feature - use subpages on mw.org, maybe?
            'info-link' => 'https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:MyExtension/SomeFeature',
            // Link to discussion about the feature - talk pages might work
            'discussion-link' => 'https://www.mediawiki.org/wiki/Extension_talk:MyExtension/SomeFeature',
            // Add feature to this group
            'group' => 'my-awesome-feature-group',
        );
    }
}

Dependency management

Next up, we can actually define dependency management per-feature. To do this we first register the name of a hook that we want to use for this with the hook "GetBetaFeatureDependencyHooks ", then we register a hook of that type that checks some dependency, and returns true if it's met or false if not.

// MyExtension.php
$wgAutoloadClasses['MyExtensionHooks'] = __DIR__ . '/MyExtensionHooks.php';
Hooks::register( 'GetBetaFeaturePreferences', 'MyExtensionHooks::getPreferences' );
Hooks::register( 'GetBetaFeatureDependencyHooks', 'MyExtensionHooks::getDependencyCallbacks' );
Hooks::register( 'CheckDependenciesForMyExtensionFeature', 'MyExtensionHooks::checkDependencies' );

// MyExtensionHooks.php
class MyExtensionHooks {

    static function getPreferences( $user, &$prefs ) {
        global $wgExtensionAssetsPath;

        $prefs['my-awesome-feature'] = array(
            // The first two are message keys
            'label-message' => 'beta-feature-message',
            'desc-message' => 'beta-feature-description',
            // Paths to images that represents the feature.
            // The image is usually different for ltr and rtl languages.
            // Images for specific languages can also specified using the language code.
            'screenshot' => array(
                'ru' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-ru.png",
                'ltr' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-ltr.png",
                'rtl' => "$wgExtensionAssetsPath/MyExtension/images/screenshot-rtl.png",
            ),
            // Link to information on the feature - use subpages on mw.org, maybe?
            'info-link' => 'https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:MyExtension/SomeFeature',
            // Link to discussion about the feature - talk pages might work
            'discussion-link' => 'https://www.mediawiki.org/wiki/Extension_talk:MyExtension/SomeFeature',
            // Mark as dependent on something
            'dependent' => true,
        );
    }

    static function getDependencyCallbacks( &$depHooks ) {
        $depHooks['my-awesome-feature'] = 'CheckDependenciesForMyExtensionFeature';
        return true;
    }

    static function checkDependencies() {
        $dependenciesMet = false;
        // Do some fancy checking and return the result
        return $dependenciesMet;
    }
}

You can ~~abuse~~ use this feature to do per-wiki disabling of features, if they're marked as dependent. But that sounds really hacky. You probably shouldn't. I can hear you thinking about it right now, just stop it.

Database stuff

There's a database table (betafeatures_user_counts) defined, and used, by BetaFeatures. But you might get confused by it if you try to use it locally.

We use the job queue to run updates for this table, when the cache expires (30 minutes TTL). If your wiki is configured to run jobs on each request, this will make about one request every 30 minutes reeeeeeally slow, but the rest will be relatively fast. If you configure your wiki to run jobs via cron, things will work much better.

Troubleshootings

Usage counts

The usage counts might not reflect exactly the number of users having some beta features activated at this precise moment. These should be interpreted as approximate numbers.

This number is computed by a job, which could be delayed or long-running. In the past, there was also a 30-minutes cache on these figures.
