Manual:Magic words/fr



Les mots magiques sont une technique pour mapper une variété de chaînes de texte wiki à un ID unique associé à une fonction. variables et parser functions utilisent cette technique. Tout le texte associé à cet ID sera remplacé par la valeur de retour de la fonction. Le mappage entre les chaînes de texte et l'ID est stocké dans la variable  dans un fichier qui peut être chargé en utilisant $wgExtensionMessagesFiles[].

Comment fonctionnent les mots magiques
Whenever MediaWiki finds text between double braces it must decide whether XXX is a variable, parser function, or template. To do so, it asks a series of questions:


 * 1) Does it have an associated magic word ID? As a first step in resolving markup of the form, MediaWiki attempts to translate XXX to a magic word ID. The translation table is defined by $magicWords.
 * 2) *If no magic word ID is associated with XXX, XXX is presumed to be a template.
 * 3) Is it a variable? If a magic word ID is found, MediaWiki next checks to see if it has any parameters.
 * 4) *If no parameters are found, MediaWiki checks to see if the magic word ID has been declared as a variable ID. To check this, it retrieves the list of magic words serving by calling  .  This method gets its list of variable IDs from a hard coded list of variable IDs (see Help:Variables) and from a list of custom variable IDs provided by all functions attached to the hook MagicWordwgVariableIDs.
 * 5) **If the magic word ID has been classified as a variable, hooks MediaWiki calls the functions associated with the event name 'ParserGetVariableValueSwitch' until one is found that recognizes the magic word and can return its value.
 * 6) Is it a parser function? If there are any parameters or if the magic word ID is missing from the list of variable magic word IDs, then MediaWiki assumes that the magic word is a parser function or template. If the magic word ID is found in the list of parser functions declared via a call to , it is treated as a parser function and rendered using the function named  .  Otherwise, it is presumed to be a template.

Définir des mots magiques
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.

Faire correspondre le code wiki aux ID des mots magiques
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':

File :

In part of the extension.json file:

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.

Associer un ID de mot magique à une fonction PHP
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:



Enregistrer les mots magiques
There is no explicit requirement to register magic word IDs. Registering the parser function or variables that use them is sufficient.

Sélecteur de comportement (mots magiques avec souligné double)
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 not 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.
