Help:Magic words/it

Le parole magiche sono stringhe di testo che MediaWiki associa con un valore restituito o una funzione, come il tempo, i dettagli sul sito o i nomi delle pagine. Questa pagina riguarda l'utilizzo delle parole magiche standard; per un riferimento tecnico, vedi.

Ci sono tre tipi generali di parole magiche:


 * Parametri di comportamento: sono parole in maiuscolo circondate da doppi caratteri di sottolineatura, ad es. __FOO__.


 * Variabili: sono parole in maiuscolo circondate da doppie parentesi graffe, ad es.  . In quanto tali, assomigliano molto ai template.


 * Funzioni parser: prendono dei parametri e sono nella forma   o  . Vedi anche.

Le variabili e le funzioni parser possono utilizzare subst:, proprio come i template. Le parole magiche dipendenti dalla pagina influenzeranno o restituiranno i dati sulla pagina "corrente" (per impostazione predefinita), anche se la parola viene aggiunta tramite un template transcluso o un messaggio di sistema incluso.

Parametri di comportamento
Un parametro di comportamento controlla l'impaginazione o il comportamento della pagina e può spesso essere utilizzato per specificare le omissioni e le inclusioni nel contenuto desiderate.

Variabili
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 e ora
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.

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.

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.

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 #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.
