-/**
- * The Message class provides methods which fulfil two basic services:
- * - fetching interface messages
- * - processing messages into a variety of formats
- *
- * First implemented with MediaWiki 1.17, the Message class is intended to
- * replace the old wfMsg* functions that over time grew unusable.
- * @see https://www.mediawiki.org/wiki/Manual:Messages_API for equivalences
- * between old and new functions.
- *
- * You should use the wfMessage() global function which acts as a wrapper for
- * the Message class. The wrapper let you pass parameters as arguments.
- *
- * The most basic usage cases would be:
- *
- * @code
- * // Initialize a Message object using the 'some_key' message key
- * $message = wfMessage( 'some_key' );
- *
- * // Using two parameters those values are strings 'value1' and 'value2':
- * $message = wfMessage( 'some_key',
- * 'value1', 'value2'
- * );
- * @endcode
- *
- * @section message_global_fn Global function wrapper:
- *
- * Since wfMessage() returns a Message instance, you can chain its call with
- * a method. Some of them return a Message instance too so you can chain them.
- * You will find below several examples of wfMessage() usage.
- *
- * Fetching a message text for interface message:
- *
- * @code
- * $button = Xml::button(
- * wfMessage( 'submit' )->text()
- * );
- * @endcode
- *
- * A Message instance can be passed parameters after it has been constructed,
- * use the params() method to do so:
- *
- * @code
- * wfMessage( 'welcome-to' )
- * ->params( $wgSitename )
- * ->text();
- * @endcode
- *
- * {{GRAMMAR}} and friends work correctly:
- *
- * @code
- * wfMessage( 'are-friends',
- * $user, $friend
- * );
- * wfMessage( 'bad-message' )
- * ->rawParams( '<script>...</script>' )
- * ->escaped();
- * @endcode
- *
- * @section message_language Changing language:
- *
- * Messages can be requested in a different language or in whatever current
- * content language is being used. The methods are:
- * - Message->inContentLanguage()
- * - Message->inLanguage()
- *
- * Sometimes the message text ends up in the database, so content language is
- * needed:
- *
- * @code
- * wfMessage( 'file-log',
- * $user, $filename
- * )->inContentLanguage()->text();
- * @endcode
- *
- * Checking whether a message exists:
- *
- * @code
- * wfMessage( 'mysterious-message' )->exists()
- * // returns a boolean whether the 'mysterious-message' key exist.
- * @endcode
- *
- * If you want to use a different language:
- *
- * @code
- * $userLanguage = $user->getOption( 'language' );
- * wfMessage( 'email-header' )
- * ->inLanguage( $userLanguage )
- * ->plain();
- * @endcode
- *
- * @note You can parse the text only in the content or interface languages
- *
- * @section message_compare_old Comparison with old wfMsg* functions:
- *
- * Use full parsing:
- *
- * @code
- * // old style:
- * wfMsgExt( 'key', [ 'parseinline' ], 'apple' );
- * // new style:
- * wfMessage( 'key', 'apple' )->parse();
- * @endcode
- *
- * Parseinline is used because it is more useful when pre-building HTML.
- * In normal use it is better to use OutputPage::(add|wrap)WikiMsg.
- *
- * Places where HTML cannot be used. {{-transformation is done.
- * @code
- * // old style:
- * wfMsgExt( 'key', [ 'parsemag' ], 'apple', 'pear' );
- * // new style:
- * wfMessage( 'key', 'apple', 'pear' )->text();
- * @endcode
- *
- * Shortcut for escaping the message too, similar to wfMsgHTML(), but
- * parameters are not replaced after escaping by default.
- * @code
- * $escaped = wfMessage( 'key' )
- * ->rawParams( 'apple' )
- * ->escaped();
- * @endcode
- *
- * @section message_appendix Appendix:
- *
- * @todo
- * - test, can we have tests?
- * - this documentation needs to be extended
- *
- * @see https://www.mediawiki.org/wiki/WfMessage()
- * @see https://www.mediawiki.org/wiki/New_messages_API
- * @see https://www.mediawiki.org/wiki/Localisation
- *
- * @since 1.17

+use MediaWiki\MediaWikiServices;
+
+/**
+ * The Message class provides methods which fulfil two basic services:
+ * - fetching interface messages
+ * - processing messages into a variety of formats
+ *
+ * First implemented with MediaWiki 1.17, the Message class is intended to
+ * replace the old wfMsg* functions that over time grew unusable.
+ * @see https://www.mediawiki.org/wiki/Manual:Messages_API for equivalences
+ * between old and new functions.
+ *
+ * You should use the wfMessage() global function which acts as a wrapper for
+ * the Message class. The wrapper let you pass parameters as arguments.
+ *
+ * The most basic usage cases would be:
+ *
+ * @code
+ * // Initialize a Message object using the 'some_key' message key
+ * $message = wfMessage( 'some_key' );
+ *
+ * // Using two parameters those values are strings 'value1' and 'value2':
+ * $message = wfMessage( 'some_key',
+ * 'value1', 'value2'
+ * );
+ * @endcode
+ *
+ * @section message_global_fn Global function wrapper:
+ *
+ * Since wfMessage() returns a Message instance, you can chain its call with
+ * a method. Some of them return a Message instance too so you can chain them.
+ * You will find below several examples of wfMessage() usage.
+ *
+ * Fetching a message text for interface message:
+ *
+ * @code
+ * $button = Xml::button(
+ * wfMessage( 'submit' )->text()
+ * );
+ * @endcode
+ *
+ * A Message instance can be passed parameters after it has been constructed,
+ * use the params() method to do so:
+ *
+ * @code
+ * wfMessage( 'welcome-to' )
+ * ->params( $wgSitename )
+ * ->text();
+ * @endcode
+ *
+ * {{GRAMMAR}} and friends work correctly:
+ *
+ * @code
+ * wfMessage( 'are-friends',
+ * $user, $friend
+ * );
+ * wfMessage( 'bad-message' )
+ * ->rawParams( '<script>...</script>' )
+ * ->escaped();
+ * @endcode
+ *
+ * @section message_language Changing language:
+ *
+ * Messages can be requested in a different language or in whatever current
+ * content language is being used. The methods are:
+ * - Message->inContentLanguage()
+ * - Message->inLanguage()
+ *
+ * Sometimes the message text ends up in the database, so content language is
+ * needed:
+ *
+ * @code
+ * wfMessage( 'file-log',
+ * $user, $filename
+ * )->inContentLanguage()->text();
+ * @endcode
+ *
+ * Checking whether a message exists:
+ *
+ * @code
+ * wfMessage( 'mysterious-message' )->exists()
+ * // returns a boolean whether the 'mysterious-message' key exist.
+ * @endcode
+ *
+ * If you want to use a different language:
+ *
+ * @code
+ * $userLanguage = $user->getOption( 'language' );
+ * wfMessage( 'email-header' )
+ * ->inLanguage( $userLanguage )
+ * ->plain();
+ * @endcode
+ *
+ * @note You can parse the text only in the content or interface languages
+ *
+ * @section message_compare_old Comparison with old wfMsg* functions:
+ *
+ * Use full parsing:
+ *
+ * @code
+ * // old style:
+ * wfMsgExt( 'key', [ 'parseinline' ], 'apple' );
+ * // new style:
+ * wfMessage( 'key', 'apple' )->parse();
+ * @endcode
+ *
+ * Parseinline is used because it is more useful when pre-building HTML.
+ * In normal use it is better to use OutputPage::(add|wrap)WikiMsg.
+ *
+ * Places where HTML cannot be used. {{-transformation is done.
+ * @code
+ * // old style:
+ * wfMsgExt( 'key', [ 'parsemag' ], 'apple', 'pear' );
+ * // new style:
+ * wfMessage( 'key', 'apple', 'pear' )->text();
+ * @endcode
+ *
+ * Shortcut for escaping the message too, similar to wfMsgHTML(), but
+ * parameters are not replaced after escaping by default.
+ * @code
+ * $escaped = wfMessage( 'key' )
+ * ->rawParams( 'apple' )
+ * ->escaped();
+ * @endcode
+ *
+ * @section message_appendix Appendix:
+ *
+ * @todo
+ * - test, can we have tests?
+ * - this documentation needs to be extended
+ *
+ * @see https://www.mediawiki.org/wiki/WfMessage()
+ * @see https://www.mediawiki.org/wiki/New_messages_API
+ * @see https://www.mediawiki.org/wiki/Localisation
+ *
