Help:Magic words/ja

マジックワードは、「値」、または (日時、サイトの詳細、ページ名のような値を返す)「関数」を表す特別な文字列です. このページでは、標準のマジックワードの使用法を説明します. 技術的な詳細は、 を参照してください.

There are three general types of magic words:


 * Behavior switches: these are uppercase words surrounded by double underscores, e.g. __FOO__.


 * Variables: these are uppercase words surrounded by double braces, e.g.  . As such, they look a lot like templates.


 * Parser functions: these take parameters and are either of the form   or  . See also.

Variables and parser functions can use subst:, just like templates. Page-dependent magic words will affect or return data about the current page (by default), even if the word is added through a transcluded template or included system message.

挙動の切り替え
A behavior switch controls the layout or behavior of the page and can often be used to specify desired omissions and inclusions in the content.

変数
Variables return information about the current page, wiki, or date. Their syntax is similar to templates. Variables marked as " [expensive] " are tracked by the software, and the number that can be included on a page is limited.

If a template name conflicts with a variable, the variable will be used (so to transclude the template    :PAGENAME you would need to write  ). In some cases, adding parameters will force the parser to invoke a template; for example,  transcludes     :CURRENTDAYNAME, not the variable.

日付と時間
次の変数はユーザのタイムゾーン(プリファレンス)に従って、現在の日付と時間を返します. デフォルトのタイムゾーンはUTCです.

MediaWikiとブラウザのキャッシングのおかげで、これらの変数は周期的に現在の時刻よりも前にページがキャッシュされた時刻が表示されます.

The date and time magic words are formatted in the wiki content language. Since, they depend on the page content language.

次の変数は上記と同じことをしますが、ユーザのプリファレンスとUTCの代わりにサイトのローカルタイムゾーンを使用します.

For more thorough time formatting, you may want to install Extension:ParserFunctions to use the #time parser function.

技術的なメタデータ
Note: Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

統計
Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example,  &rarr;  and   &rarr; ).

Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example  and , or   and  ). Also applicable to  hereinbefore.

The number magic words are formatted in the wiki content language. Since, it depends on the page content language.

ページ名
The  and   magic words only work in namespaces that have subpages enabled. See for information on enabling subpages.

As of, these can all take a parameter, allowing specification of the page to be operated on, instead of just the current page:
 * &rarr; 

For example, if page name is "L'Aquila", the following code will produce the string "Numeric char encoding":

URL エンコードされたページ名
The following are equivalents encoded for use in MediaWiki URLs (i.e. spaces replaced with underscores and some characters HTML escaped using numeric character encoding):



Note that,   and   have distinct implementations. See Manual:PAGENAMEE encoding for details.

名前空間
The following are equivalents encoded for use in MediaWiki URLs (spaces replaced with underscores and some characters percent-encoded):



As of, these can take a full-page-name parameter and will return the requested namespace associated with that page, instead of with the current page:

Parameter must not be a namespace name:
 * &rarr; 
 * &rarr; 
 * &rarr; 
 * &rarr;   (Empty)

パーサー関数
Parser functions are very similar to variables, but take one or more parameters (technically, any magic word that takes a parameter is a parser function), and the name is sometimes prefixed with a hash to distinguish them from templates.

This page only describes parser functions that are integral to the MediaWiki software. Other parser functions may be added by MediaWiki extensions such as the. For those see Help:Extension:ParserFunctions.

名前空間
returns the current localized name for the namespace with that index, canonical name, or local alias. Thus,  , and   (an old name for the File namespace) all return "    ". On a wiki where the content language is French,  is also valid, but   (the localisation of "File" in German) is not.

is the equivalent encoded for MediaWiki URLs. It does the same, but it replaces spaces with underscores, making it usable in external links.

Don't confuse localised namespaces with custom namespaces.

整形
See also: Extension:StringFunctions.

地域化
Here are the magic words which are used as main localisation tools. Other magic words will often depend on the wiki's locale and configuration or on the chosen language: see in particular, ,. More magic words are added by the Translate extension.

The usage of these magic words can be very complex, and the documentation is currently incomplete; there's some more info on PLURAL, GRAMMAR, GENDER.
