Help:Magic words/pt-br

Palavras mágicas são sequências de texto que o MediaWiki associa com um valor de retorno ou função, como tempo, detalhes do site ou nomes de página. Esta página é sobre o uso de palavras mágicas padrão; para uma referência técnica, veja.

Existem três tipos gerais de palavras mágicas:


 * Comutadores de comportamento: estas são palavras em maiúsculas, rodeadas por sublinhados duplos, p.ex. __FOO__.


 * Variáveis: estas são palavras em maiúsculas, rodeadas por chaves duplas, p.ex.  . Como tal, eles se parecem muito com os templates.


 * Funções do analisador sintático: estas funções usam parâmetros e se apresentam da forma   ou da forma  . Veja também.

Variáveis ​​e funções do analisador podem usar subst:, exatamente como as predefinições. Palavras mágicas dependentes de página afetarão ou retornarão dados sobre a página atual (por padrão), mesmo que a palavra seja adicionada através de um modelo de transcluídos ou incluído mensagens do sistema.

Comutadores de comportamento
Um comutador de comportamento controla o layout ou o comportamento da página e muitas vezes pode ser usado para especificar omissões e inclusões desejados no conteúdo.

Variáveis
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.

Date and time
The following variables return the current date and time in UTC.

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 Extension:ParserFunctions to use the #time parser function.

Technical metadata
Note: Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

Statistics
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.

Page names
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.

Namespaces
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)

Parser functions
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.

Namespaces
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.

Formatting

Localization
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.
