| 51 | /** |
| 52 | * The Message class deals with fetching and processing of interface message |
| 53 | * into a variety of formats. |
| 54 | * |
| 55 | * First implemented with MediaWiki 1.17, the Message class is intended to |
| 56 | * replace the old wfMsg* functions that over time grew unusable. |
| 57 | * @see https://www.mediawiki.org/wiki/Manual:Messages_API for equivalences |
| 58 | * between old and new functions. |
| 59 | * |
| 60 | * The preferred way to create Message objects is via the msg() method of |
| 61 | * of an available RequestContext and ResourceLoader Context object; this will |
| 62 | * ensure that the message uses the correct language. When that is not |
| 63 | * possible, the wfMessage() global function can be used, which will cause |
| 64 | * Message to get the language from the global RequestContext object. In |
| 65 | * rare circumstances when sessions are not available or not initialized, |
| 66 | * that can lead to errors. |
| 67 | * |
| 68 | * The most basic usage cases would be: |
| 69 | * |
| 70 | * @code |
| 71 | * // Initialize a Message object using the 'some_key' message key |
| 72 | * $message = $context->msg( 'some_key' ); |
| 73 | * |
| 74 | * // Using two parameters those values are strings 'value1' and 'value2': |
| 75 | * $message = $context->msg( 'some_key', |
| 76 | * 'value1', 'value2' |
| 77 | * ); |
| 78 | * @endcode |
| 79 | * |
| 80 | * @section message_global_fn Global function wrapper: |
| 81 | * |
| 82 | * Since msg() returns a Message instance, you can chain its call with a method. |
| 83 | * Some of them return a Message instance too so you can chain them. |
| 84 | * You will find below several examples of msg() usage. |
| 85 | * |
| 86 | * Fetching a message text for interface message: |
| 87 | * |
| 88 | * @code |
| 89 | * $button = Xml::button( |
| 90 | * $context->msg( 'submit' )->text() |
| 91 | * ); |
| 92 | * @endcode |
| 93 | * |
| 94 | * A Message instance can be passed parameters after it has been constructed, |
| 95 | * use the params() method to do so: |
| 96 | * |
| 97 | * @code |
| 98 | * $context->msg( 'welcome-to' ) |
| 99 | * ->params( $wgSitename ) |
| 100 | * ->text(); |
| 101 | * @endcode |
| 102 | * |
| 103 | * {{GRAMMAR}} and friends work correctly: |
| 104 | * |
| 105 | * @code |
| 106 | * $context->msg( 'are-friends', |
| 107 | * $user, $friend |
| 108 | * ); |
| 109 | * $context->msg( 'bad-message' ) |
| 110 | * ->rawParams( '<script>...</script>' ) |
| 111 | * ->escaped(); |
| 112 | * @endcode |
| 113 | * |
| 114 | * @section message_language Changing language: |
| 115 | * |
| 116 | * Messages can be requested in a different language or in whatever current |
| 117 | * content language is being used. The methods are: |
| 118 | * - Message->inContentLanguage() |
| 119 | * - Message->inLanguage() |
| 120 | * |
| 121 | * Sometimes the message text ends up in the database, so content language is |
| 122 | * needed: |
| 123 | * |
| 124 | * @code |
| 125 | * wfMessage( 'file-log', |
| 126 | * $user, $filename |
| 127 | * )->inContentLanguage()->text(); |
| 128 | * @endcode |
| 129 | * |
| 130 | * Checking whether a message exists: |
| 131 | * |
| 132 | * @code |
| 133 | * $context->msg( 'mysterious-message' )->exists() |
| 134 | * // returns a boolean whether the 'mysterious-message' key exist. |
| 135 | * @endcode |
| 136 | * |
| 137 | * If you want to use a different language: |
| 138 | * |
| 139 | * @code |
| 140 | * $userLanguage = $user->getOption( 'language' ); |
| 141 | * wfMessage( 'email-header' ) |
| 142 | * ->inLanguage( $userLanguage ) |
| 143 | * ->plain(); |
| 144 | * @endcode |
| 145 | * |
| 146 | * @note You can parse the text only in the content or interface languages |
| 147 | * |
| 148 | * @see https://www.mediawiki.org/wiki/Manual:Messages_API |
| 149 | * @see https://www.mediawiki.org/wiki/Localisation |
