Notas adicionales

Para obtener la diferencia entre dos páginas, un número de revisión, un título de página o un ID de página para ambos from y to debe ser pasado.

Comparación relativa en primera y última revisión

  • Puedes solicitar una comparación relativa a prev en la primera revisión de una página, esto dará como resultado que el texto completo de la primera revisión se devuelva como la diferencia. Ten en cuenta que esto no es exacto, ya que en algunos casos puede haber contenido predeterminado para la página antes de su primera revisión. La propiedad de fromrevid estará ausente de los resultados.
  • Del mismo modo, puedes solicitar la próxima comparación relativa en la última revisión de una página.
  • (Nota: esta es la última revisión al momento de escribir este tema. Debido a que la página está protegida, probablemente no debería cambiar). El resultado es un diferencial vacío y los torevid estarán ausentes. A diferencia de la mayoría de comparaciones de revisiones, estos resultados cambiarán si se crea una nueva revisión.

Este comportamiento en la API es histórico. No es consistente con el modelo conceptual del historial de la página como una serie de revisiones. No hay una revisión previous para comparar con la primera revisión, ni hay una revisión next para comparar con la última. Debido a esto, las futuras versiones de MediaWiki pueden dar resultados diferentes para esta llamada a la API.

Uso de la salida HTML

Los prop valores diff y parsedcomment devuelven fragmentos de HTML. El HTML diff es una lista de filas de tabla (elementos de ‎<tr>) que se deben insertar en una tabla con al menos el siguiente marcado:

<table class="diff">
  <colgroup>
    <col class="diff-marker">
    <col class="diff-content">
    <col class="diff-marker">
    <col class="diff-content">
  </colgroup>
  <tbody>
    DIFF HTML SNIPPET GOES HERE
  </tbody>
</table>

Para mostrar metadatos también, p.ej. al usuario o comentario, agrega filas adicionales y coloca los metadatos dentro de un elemento de <td colspan="2">.

Para asegurarte de que esta diferencia se muestre correctamente (p.ej., que el marcador de diferencia y las columnas de contenido no tengan el mismo ancho), puedes agregar el módulo mediawiki.diff.styles ResourceLoader a tu página:

<link rel="stylesheet" href="https://www.mediawiki.org/w/load.php?modules=mediawiki.diff.styles&only=styles">

Si deseas mostrar parsedcomment, igualment querrás agregar el módulo mediawiki.legacy.shared, que incluye algunos estilos básicos para comentarios y comentarios automáticos:

<link rel="stylesheet" href="https://www.mediawiki.org/w/load.php?modules=mediawiki.legacy.shared&only=styles">

Y si quieres mostrar tanto el HTML diff como el parsedcomment en la página, puedes combinar estas dos etiquetas en una:

<link rel="stylesheet" href="https://www.mediawiki.org/w/load.php?modules=mediawiki.legacy.shared|mediawiki.diff.styles&only=styles">
