/**
|
|
* 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', array( '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', array( '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
|
