Manual:Magic words/ja



マジックワードとは単一の関数のIDに対応するさまざまなウィキテキスト文字列を対応付けする技術で、変数 にもパーサ関数にも使われています. 特定のIDに対応付けされたさまざまなテキストは、関数の戻り値に置換されます. $wgExtensionMessagesFiles[]を使って読み込んだファイルの 変数には、IDに対応するすべての文字列を格納します.

既定のマジックワードはで実装されています.

マジックワードの動作の仕組み
MediaWikiでは二重の角括弧 に挟まれた文字列を検地すると、その中に含まれるXXXが変数もしくはパーサ関数あるいはテンプレートのどれに該当するか識別必要があります. そのためにいくつかの問いを解きます.


 * 1) 文字列にはマジックワードのIDが付帯するか? という文字列のマークアップ解決において最初にMediaWikiはXXXをマジックワードIDに変換できるかどうか検討します. 変換テーブルは$magicWordsによって定義されます.
 * 2) *付帯するマジックワードIDが見つからない場合、XXXはテンプレートだと判断されます.
 * 3) 関数ではないか? マジックワードIDが検出 される と、MediaWikiは次にパラメータがあるかどうか確認します.
 * 4) *パラメータを検出しなかった場合、MediaWikiはマジックワードIDが有効なIDかどうか確認します. 手順は を呼び出し、表示されるマジックワードのリストを取得します. この方法により、ハードコードされた変数ID（ヘルプ:関数を参照）とMagicWordwgVariableIDsフックに接続する関数をすべて提供するカスタム変数IDのリストから、変数IDのリストを取得します.
 * 5) **If the magic word ID has been classified as a variable, hooks MediaWiki calls the functions associated with the event name 'ParserGetVariableValueSwitch' until one is found that recognizes the magic word and can return its value.
 * 6) Is it a parser function? If there are any parameters or if the magic word ID is missing from the list of variable magic word IDs, then MediaWiki assumes that the magic word is a parser function or template. If the magic word ID is found in the list of parser functions declared via a call to , it is treated as a parser function and rendered using the function named  .  Otherwise, it is presumed to be a template.
 * 1) Is it a parser function? If there are any parameters or if the magic word ID is missing from the list of variable magic word IDs, then MediaWiki assumes that the magic word is a parser function or template. If the magic word ID is found in the list of parser functions declared via a call to , it is treated as a parser function and rendered using the function named  .

マジックワードを定義する
For magic words to do their magic we must define two things:
 * a mapping between wiki text and a magic word ID
 * a mapping between a magic word ID and some php function that interprets the magic word.

ウィキテキストからマジックワード ID への対応付け
The variable $magicWords is used to associate each magic word ID with a language-dependent array that describes all the text strings that mapped to the magic word ID. Important: This only sets up the back end i18n mapping, you still have to write other code to make MediaWiki use the magic word for anything

The first element of this array is an integer flag indicating whether or not the magic word is case sensitive. The remaining elements are a list of text that should be associated with the magic word ID. If the case sensitive flag is 0, any case variant of the names in the array will match. If the case sensitive flag is 1, only exact case matches will be associated with the magic word ID. Thus the format is

This association is created by $magicWords in a file registered using $wgExtensionMessagesFiles[].

In the example below, a Spanish MediaWiki installation will associate the magic word ID 'MAG_CUSTOM' with "personalizado", "custom", "PERSONALIZADO", "CUSTOM" and all other case variants. In an English MediaWiki only "custom" in various case combinations will be mapped to 'MAG_CUSTOM':

Note that "ExampleMagic" is a different to the key you would use for a plain internationalization file (normally just the title of the extension, i.e. "Example"). "Magic" has been appended deliberately so one does not overwrite the other.

マジックワード ID と PHP 関数の関連付け
The mechanism for associating magic word IDs with rendering functions depends on whether the magic word will be used as a parser function or a variable. For more information, please see:

In MediaWiki 1.8 and beyond there is no explicit requirement to register magic word IDs. Registering the parser function or variables that use them is sufficient. For versions prior to 1.8, see below.

1.8より前のバージョンのMediaWikiのマジックワード
1.8 より前のバージョンの MediaWiki では以下の点が異なります:

 Manual:Hooks/LanguageGetMagic did not pass a language parameter. To simulate this parameter, extensions backported to 1.7 or earlier can extract the language of $wgContLang on their own and proceed as normal and/or offer a language independent process for selecting the ID-text mapping. Extensions that used magic words had to explicitly register their magic word IDs using the hook MagicWordMagicWords. This method simply asked the implementer to supply the ID of the magic word.

 

挙動の切り替え(二重の下線で囲まれたマジックワード)
Behavior switches are a special type of magic word. They can be recognized by their use of double underscores (rather than double braces). For example,.

These magic words typically do not output any content, but instead change the behavior of a page and/or set a page property. These magic words are listed in  and also at Help:Magic words#Behavior switches. The effect of each behavior switch is defined in. If no specific effect is defined, the magic word will simply set a page property in the page_props table.
