Manual:Magic words/es



Palabras Mágicas es una técnica empleada para mapear un identificador (ID) con una variedad de cadenas del tipo wiki texto, que están asociadas a una función. Tanto las variables y las funciones de parseo emplean esta técnica. Todo texto mapeado con dicho ID será remplazado con el valor resultante de la función. El mapeo entre el texto y el ID se almacena en la variable $magicWords en un archivo que puede cargarse empleando $wgExtensionMessagesFiles[].

Las palabras mágicas predeterminadas están implementadas en CoreParserFunctions.php.

Cómo funcionan las palabras mágicas
Donde quiera que MediaWiki encuentra texto entre doble llave  decide si XXX corresponde a variable, función de parseo, o plantilla.


 * 1) El texto está asociado a un ID de palabra mágica?  Es el primer paso para resolver la forma de marcado, it is treated as a parser function and rendered using the function named  .  Otherwise, it is presumed to be a template.

Definir palabras mágicas
For magic words to do their magic we must define two things:
 * a mapping between wiki text and a magic word ID
 * a mapping between a magic word ID and some php function that interprets the magic word.

Mapping wiki text to magic word IDs
The variable $magicWords is used to associate each magic word ID with a language-dependent array that describes all the text strings that mapped to the magic word ID. Important: This only sets up the back end i18n mapping, you still have to write other code to make MediaWiki use the magic word for anything

The first element of this array is an integer flag indicating whether or not the magic word is case sensitive. The remaining elements are a list of text that should be associated with the magic word ID. If the case sensitive flag is 0, any case variant of the names in the array will match. If the case sensitive flag is 1, only exact case matches will be associated with the magic word ID. Thus the format is

This association is created by $magicWords in a file registered using $wgExtensionMessagesFiles[].

In the example below, a Spanish MediaWiki installation will associate the magic word ID 'MAG_CUSTOM' with "personalizado", "custom", "PERSONALIZADO", "CUSTOM" and all other case variants. In an English MediaWiki only "custom" in various case combinations will be mapped to 'MAG_CUSTOM':

Archivo

Archivo de inicialización de extensión :

Note that "ExampleMagic" is a different to the key you would use for a plain internationalization file (normally just the title of the extension, i.e. "Example"). "Magic" has been appended deliberately so one does not overwrite the other.

Associating a magic word ID with a PHP function
The mechanism for associating magic word IDs with rendering functions depends on whether the magic word will be used as a parser function or a variable. For more information, please see:


 * Manual:Parser functions
 * Manual:Variables

Registrar palabras mágicas
In MediaWiki 1.8 and beyond there is no explicit requirement to register magic word IDs. Registering the parser function or variables that use them is sufficient. For versions prior to 1.8, see below.

Localización

 * ''See Help:Magic words#Localisation for help.

You can read more on definition and usage of magic words for localisation at Localisation#PLURAL and GENDER support in JavaScript, Localisation#Localizing namespaces and special page aliases, Localisation#Switches in messages…; Localisation#Be aware of PLURAL use on all numbers, Localisation#Users have grammatical genders, Avoid  in messages.

Palabras mágicas en versiones de MediaWiki anteriores a 1.8
Las versiones de MediaWiki previas a 1.8 difieren en lo siguiente:

 Manual:Hooks/LanguageGetMagic did not pass a language parameter. To simulate this parameter, extensions backported to 1.7 or earlier can extract the language of $wgContLang on their own and proceed as normal and/or offer a language independent process for selecting the ID-text mapping. Extensions that used magic words had to explicitly register their magic word IDs using the hook MagicWordMagicWords. This method simply asked the implementer to supply the ID of the magic word.

 

Behavior switches (double underscore magic words)
Behavior switches are a special type of magic word. They can be recognized by their use of double underscores (rather than double braces). For example,.

These magic words typically do no output any content, but instead change the behavior of a page and/or set a page property. These magic words are listed in  and also at Help:Magic words#Behavior switches. The effect of each behavior switch is defined in. If no specific effect is defined, the magic word will simply set a page property in the page_props table.
