Manual:Parser functions/ko

Parser functions, added in MediaWiki 1.7, are a type of extension that integrate closely with the parser. The phrase "parser function" should not be confused with Extension:ParserFunctions, which is a collection of simple parser functions. (See Help:Extension:ParserFunctions for those.)

설명
Whereas a Tag extension is expected to take unprocessed text and return HTML to the browser, a parser function can 'interact' with other wiki elements in the page. For example, the output of a parser function could be used as a template parameter or in the construction of a link.

The typical syntax for a parser function is:

For more information, see for. This documentation states:
 * The callback function should have the form:
 * Or with :
 * Or with :

Creating a parser function is slightly more complicated than creating a new tag because the function name must be a magic word, a keyword that supports aliases and localization.

단순 예제
Below is an example of an extension that creates a parser function.

The registration goes into extension.json, the code into ExampleExtension.class.php:

Another file, ExampleExtension.i18n.php, should contain:

With this extension enabled,



produces:


 * param1 is hello and param2 is hi and param3 is hey

For longer functions, you may want to split the hook functions out to a _body.php or .hooks.php file and make them static functions of a class. Then you can load the class with and call the static functions in the hooks; e.g.:

Put this in your  file: Then put this is in your  file:
 * See: writing an event handler for other styles.

캐시
As with tag extensions, $parser->disableCache may be used to disable the cache for dynamic extensions.

To have the wikitext returned by your parser function be fully parsed (including expansion of templates), set the  option to false when returning:

It seems the default value for  changed from false to true, at least in some situations, sometime around version 1.12.

Conversely, to have your parser function return HTML that remains unparsed, rather than returning wikitext, use this:

However, This is a test. will produce something like this:

This is

param1 is hello and param2 is hi and param3 is hey a test.

This happens due to a hardcoded "\n\n" that is prepended to the HTML output of parser functions. To avoid that and make sure the HTML code is rendered inline to the surrounding text, you can use this:

이름 정하기
By default, MW adds a hash character (number sign, "#") to the name of each parser function. To suppress that addition (and obtain a parser function with no "#" prefix), include the SFH_NO_HASH constant in the optional flags argument to setFunctionHook, as described below.

When choosing a name without a hash prefix, note that transclusion of a page with a name starting with that function name followed by a colon is no longer possible. In particular, avoid function names equal to a namespace name. In the case that interwiki transclusion is enabled, also avoid function names equal to an interwiki prefix.

For more details of the interface into the parser, see the documentation for setFunctionHook in includes/Parser.php. Here's a (possibly dated) copy of those comments:

function setFunctionHook( $id, $callback, $flags = 0 ) 변수:


 * string $id - The magic word ID
 * mixed $callback - The callback function (and object) to use
 * integer $flags - Optional, set it to the SFH_NO_HASH constant to call the function without "#".

Return value: The old callback function for this name, if any

Create a function, e.g.,. The callback function should have the form:

The callback may either return the text result of the function, or an array with the text in element 0, and a number of flags in the other elements. The names of the flags are specified in the keys. Valid flags are:


 * found : The text returned is valid, stop processing the template. This is on by default.
 * nowiki : Wiki markup in the return value should be escaped
 * noparse : Unsafe HTML tags should not be stripped, etc.
 * noargs : Don't replace triple-brace arguments in the return value
 * isHTML : The returned text is HTML, armour it against wikitext transformation

지명 변수
Parser functions do not support named parameters the way templates and tag extensions do, but it is occasionally useful to fake it. Users are often accustomed to using vertical bars ( | ) to separate arguments, so it's nice to be able to do that in the parser function context, too. Here's a simple example of how to accomplish this:
