/**
- * OBS!!! *EXPERIMENTAL* This class is still under discussion.
- *
* This class provides methods for fetching interface messages and
* processing them into variety of formats that are needed in MediaWiki.
*
*
* Examples:
* Fetching a message text for interface message
- * $button = Xml::button( Message::key( 'submit' )->text() );
+ * $button = Xml::button( wfMessage( 'submit' )->text() );
+ * </pre>
* Messages can have parameters:
- * Message::key( 'welcome-to' )->params( $wgSitename )->text();
+ * wfMessage( 'welcome-to' )->params( $wgSitename )->text();
* {{GRAMMAR}} and friends work correctly
- * Message::key( 'are-friends' )->params( $user, $friend );
- * Message::key( 'bad-message' )->rawParams( '<script>...</script>' )->escaped()
+ * wfMessage( 'are-friends', $user, $friend );
+ * wfMessage( 'bad-message' )->rawParams( '<script>...</script>' )->escaped();
+ * </pre>
* Sometimes the message text ends up in the database, so content language is needed.
- * Message::key( 'file-log' )->params( $user, $filename )->inContentLanguage()->text()
+ * wfMessage( 'file-log', $user, $filename )->inContentLanguage()->text()
+ * </pre>
* Checking if message exists:
- * Message::key( 'mysterious-message' )->exists()
+ * wfMessage( 'mysterious-message' )->exists()
+ * </pre>
* If you want to use a different language:
- * Message::key( 'email-header' )->language( $user->getOption( 'language' ) )->plain()
+ * wfMessage( 'email-header' )->inLanguage( $user->getOption( 'language' ) )->plain()
* Note that you cannot parse the text except in the content or interface
* languages
+ * </pre>
*
*
* Comparison with old wfMsg* functions:
*
* Use full parsing.
* wfMsgExt( 'key', array( 'parseinline' ), 'apple' );
- * === Message::key( 'key' )->params( 'apple' )->parse();
+ * === wfMessage( 'key', 'apple' )->parse();
+ * </pre>
* 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.
* wfMsgExt( 'key', array( 'parsemag' ), 'apple', 'pear' );
- * === Message::key( 'key' )->params( 'apple', 'pear' )->text();
+ * === wfMessage( 'key', 'apple', 'pear' )->text();
+ * </pre>
*
* Shortcut for escaping the message too, similar to wfMsgHTML, but
* parameters are not replaced after escaping by default.
- * $escaped = Message::key( 'key' )->rawParams( 'apple' )->escaped();
+ * $escaped = wfMessage( 'key' )->rawParams( 'apple' )->escaped();
+ * </pre>
*
* TODO:
- * * test, can we have tests?
- * * sort out the details marked with fixme
- * * should we have _m() or similar global wrapper?
+ * - test, can we have tests?
+ * - sort out the details marked with fixme
