Help:Magic words/ca

Les paraules màgiques són cadenes de text que el MediaWiki associa amb una funció o un valor, com per exemple l'hora, dades del lloc o noms de pàgina. Aquesta pàgina és sobre l'ús de paraules màgiques tipificades. Per a informació tècnica vegeu

Hi ha tres categories generals de paraules màgiques:


 * Controladors de comportament: són paraules en majúscules entre dues ratlles baixes, per exemple __FOO__.


 * Variables: són paraules en majúscules entre claus dobles, per exemple  . S'assemblen molt a les plantilles.


 * Funcions d'analitzador o funcions parser: prenen paràmetres i són bé de la forma   o bé  . Vegeu també.

Les variables i les funcions d'analitzador poden utilitzar subst:, igual que les plantilles. Les paraules màgiques pàgina-depenents afectaran o retornaran dades sobre la pàgina actual (per defecte), encara que la paraula s'afegeixi a través d'una plantilla transclosa o d'un missatge del sistema inclòs.

Controladors de comportament
Un controlador de comportament determina el disseny o el comportament de la pàgina i, sovint es pot utilitzar per especificar, volgudament, algunes omissions i inclusions en el contingut.

Variables
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.

Data i hora
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 to use the #time parser function.

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

Estadístiques
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.

Noms de pàgina
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":

Noms de pàgina codificats com a URL
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.

Espais de noms
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)

Funcions d'analitzador
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.

Espais de noms
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.

Formatació

Localització
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.
