Help:Magic words/zh

魔术字是MediaWiki软件所识别的特定字符串，它们可以返回特定的值或触发其他的功能：比如时间、站点设置或是页面名称等等. 本页所描述的均是标准魔术字的用法；开发人员请参考.

魔术字有三种类型：


 * 状态开关：以两个下划线“__”为前后缀的大写单词，例如__FOO__.


 * 变量：字符被两个大括号括起来，所有字母大写，例如 . 用法与模板类似.


 * 解析器函数：一些形如或的魔术字，在使用时包含参数，且大小写不敏感. 另可参见.

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.

行为开关
状态开关可以控制页面的显示方式或其他行为. 它往往用于排除或加入特定的页面内容.

变量
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.

日期和时间
以下的变量返回当前的日期和时间，遵照用户的时区选项，默认为UTC时间.

Due to MediaWiki and browser caching, these variables frequently show when the page was cached rather than the current time.

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

The following variables do the same as the preceding ones, but using the site's server config or $wgLocaltimezone.

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

技术元数据
Note: Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

统计
Numbers returned by these variables normally contain separators (commas, dots 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.

页面名称
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 encoded page names
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.

名字空间
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)

解析器函数
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.

名字空间
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.

本地化
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 #Date and time, #Formatting, #Miscellaneous. More magic words are added by the.

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.

Transclusion modifiers
usually transcludes another page, by default from the Template:namespace. These magic words modify that behavior.
