Magic Words {#magicword}
====================================
Magic words are localizable keywords used in wikitext. They are used for many
small fragments of text, including:
* The names of parser functions e.g. `{{urlencode:...}}`
* The names of variables, e.g. `{{CURRENTDAY}}`
* Double-underscore behavior switches, e.g. `__NOTOC__`
* Image link parameter names
Magic words have a synonym list, with the canonical English word always present,
and a case sensitivity flag. The MagicWord class provides facilities for
matching a magic word by converting it to a regex.
A magic word has a unique ID. Often, the ID is the canonical English synonym in
lowercase.
To add a magic word in an extension, add a file to the **ExtensionMessagesFiles**
attribute in extension.json,
and in that file, set a variable called **$magicWords**. This array is associative
with the language code in the first dimension key and an ID in the second key. The
third level array is numerically indexed: the element with key 0 contains the case
sensitivity flag, with 0 for case-insensitive and 1 for case-sensitive. The
subsequent elements of the array are the synonyms in the relevant language.
To add a magic word in core, add it to $magicWords in MessagesEn.php, following the
comment there.
For example, to add a new parser function in an extension: create a file called
**ExtensionName.i18n.magic.php** with the following contents:
```php
<?php
$magicWords = [];
$magicWords['en'] = [
// Case insensitive.
'mag_custom' => [ 0, 'custom' ],
];
$magicWords['es'] = [
'mag_custom' => [ 0, 'aduanero' ],
];
```
Then in extension.json:
```json
{
"ExtensionMessagesFiles": {
"ExtensionNameMagic": "ExtensionName.i18n.magic.php"
},
"Hooks": {
"ParserFirstCallInit": "MyExtensionHooks::onParserFirstCallInit"
}
}
```
It is important that the key "ExtensionNameMagic" is unique. It must not be used
by another extension.
And in the class file:
```php
<?php
class MyExtensionHooks {
public static function onParserFirstCallInit( $parser ) {
$parser->setFunctionHook( 'mag_custom', [ self::class, 'expandCustom' ] );
return true;
}
public static function expandCustom( $parser, $var1, $var2 ) {
return "custom: var1 is $var1, var2 is $var2";
}
}
```
