La expresión «función del analizador» no debería confundirse con $2, que es una colección de funciones simples del analizador.

Por ejemplo, la salida de una función de análisis se podría usar como <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/Help:Templates?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te#Parameters" title="Special:MyLanguage/Help:Templates">parámetro de una plantilla</a> o en la construcción de un <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/Help:Link?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Special:MyLanguage/Help:Link">enlace</a>.</p> <p>La sintaxis típica de una función del analizador es:</p> <blockquote> <p>{{ #functionname: param1 | param2 | param3 }}</p> </blockquote> <p>Para más información, consulta <span class="plainlinks"><a class="external text" href="https://translate.google.com/website?sl=auto&tl=te&hl=te&u=https://doc.wikimedia.org/mediawiki-core/master/php/classMediaWiki_1_1Parser_1_1Parser.html%23a34da5613dad9dd0a5e921aa7bceba3cf">la documentación</a></span> de <code class="mw-highlight mw-highlight-lang-php mw-content-ltr" style="" dir="ltr"><span class="nx">Parser</span><span class="o">::</span><span class="na">setFunctionHook</span> <span class="p">(</span> <span class="nv">$id</span><span class="p">,</span> <span class="nv">$callback</span><span class="p">,</span> <span class="nv">$flags</span> <span class="o">=</span> <span class="mi">0</span> <span class="p">)</span></code>.

La segunda pasa todos los argumentos como una matriz de <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/Manual:PPNode.php?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Special:MyLanguage/Manual:PPNode.php">PPNode</a><span style="display:none"><a href="https://www-mediawiki-org.translate.goog/wiki/Manual:PPNode.php?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Manual:PPNode.php"> </a></span>, excepto el primero (<code>$args[0]</code>), que en la actualidad es texto, aunque esto puede cambiar en el futuro.

El objeto de marco también puede subir por el árbol del documento para obtener información sobre el llamador y dispone de funciones para determinar y gestionar la profundidad de la llamada, el tiempo

El número de función del analizador costosas en cualquier página dada está limitado por el valor de <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/Manual:$wgExpensiveParserFunctionLimit?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Special:MyLanguage/Manual:$wgExpensiveParserFunctionLimit">$wgExpensiveParserFunctionLimit</a><span style="display:none"><a href="https://www-mediawiki-org.translate.goog/wiki/Manual:$wgExpensiveParserFunctionLimit?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Manual:$wgExpensiveParserFunctionLimit"> </a></span>. La propia función es la que decide qué se considera «costoso», pero, por lo general, debe considerarse cualquier cosa susceptible de causar un retraso que se prolongue más allá del simple procesamiento de datos. Esto incluye, por ejemplo, lecturas y escrituras en la base de datos, lanzar un script de la shell de forma síncrona o la manipulación de archivos. Por otra parte, no se tienen por qué marcar así todas estas funciones. Semantic MediaWiki, por ejemplo, solo marca como costosa una parte de sus lecturas de la base de datos. Esto se debe a que, en determinadas páginas con un uso intensivo de datos, podría sobrepasar fácilmente los límites normales de funciones del analizador costosas. En casos así, el potencial de un rendimiento notablemente más lento que no se marca como costoso es un compromiso con tener la funcionalidad que ofrece SMW.</p> <p>Para marcar tu función del analizador como costoso desde dentro del cuerpo del código de la función, usa <code class="mw-highlight mw-highlight-lang-php mw-content-ltr" dir="ltr"><span class="nv">$result</span> <span class="o">=</span> <span class="nv">$parser</span><span class="o">-></span><span class="na">incrementExpensiveFunctionCount</span><span class="p">();</span></code>. El valor de retorno será <code class="mw-highlight mw-highlight-lang-php mw-content-ltr" style="" dir="ltr"><span class="k">false</span></code> si se ha alcanzado o excedido el límite de funciones costosas.</p> <p><span id="Named_parameters"></span></p> <div class="mw-heading mw-heading2"> <h2 id="Parámetros_nombrados"><span id="Par.C3.A1metros_nombrados"></span>Parámetros nombrados</h2> </div> <p>Las funciones del analizador no permiten el uso de parámetros nombrados de la manera en que lo hacen las plantillas y extensiones de marcado, pero a veces puede ser útil imitarlos. Los usuarios a menudo están acostumbrados a usar barras verticales ( <code>|</code> ) para separar argumentos, así que está bien poder hacerlo también en el contexto de las funciones de análisis. He aquí un ejemplo sencillo de cómo conseguirlo:</p> <div style="overflow:auto;" class="mw-highlight mw-highlight-lang-php mw-content-ltr" dir="ltr"> <pre><span></span><span class="k">function</span>
