Transclusion/es

"Transclusión" es generalmente la inclusión del contenido de un documento en otro por referencia. En el contexto de wiki, es el uso de la funcionalidad de plantilla de MediaWiki para incluir el mismo contenido en documentos múltiples sin la necesidad de editar los documentos por separado.

Cómo funciona transclusión


 Sintaxis

Si la fuente está en el espacio de nombres de la Plantilla (por ejemplo, "Template:Welcome"), sólo hay que usar el nombre en sí, solo:

Si la fuente está en el espacio de nombres del Artículo Principal (por ejemplo, "VisualEditor"), se deben agregar dos puntos delante del nombre:

Si la fuente se encuentra en cualquier otro espacio de nombres (por ejemplo, "User:Example"), debe utilizar el nombre completo, incluido el espacio de nombres:

Si la fuente es una subpágina de la página de destino, (por ejemplo, "Transclusion/ja"), puede simplemente especificar el nombre de la subpágina sin importar el espacio de nombre:



Para transcluir cualquier página fuente (dentro de un solo proyecto MediaWiki, como Wikipedia) dentro de otra página objetivo, incluya el siguiente código:

Siempre que se renderice la página de destino A, todo el contenido de la página de origen B (en este caso, SOMEPAGE), se renderizará en el lugar donde se colocó la etiqueta de transclusión.

For example, you might decide to place a welcome message on every newcomer's talk page. Transclusion creates a "live" link between the template-page and the target-page(s) upon which the message should appear. When the template is edited, all the target-pages are edited too.

You might also decide to create a (template) page with your mailing address and include that template on not only your page, but all your friends' pages as well. When you move your television and couch to another apartment, you can change your address template, and that new information will automatically update on all your friends' pages.

Etimología
Ted Nelson acuñó el término "transclusión", así como "hipertexto" y "hipermedia", en su libro de 1982 ''Máquinas Literarias".

Transclusión parcial
By using "noinclude", "onlyinclude" and "includeonly" markup, it is possible to transclude part of a page rather than all of it. Such partial transclusions can also be achieved by transcluding from other pages such as subpages. It is often desirable not to transclude some information, such as template documentation and categories.

Transclusion markup

 * noinclude - The markup  means that the text between the tags will not be transcluded onto another page and will appear only on the page itself. This is useful for template documentation and categories.
 * includeonly - The markup  means that the text between the tags will only be used when the page is transcluded onto another page, and will not appear on the page itself. This can be useful, for example, for adding categories to pages transcluding a template, without adding the template itself to these categories.
 * onlyinclude - The markup  indicates that only text surrounded by "onlyinclude" markup should be transcluded onto another page, but will appear on the page itself if not accompanied by "includeonly" tags as well. This is the most subtle of the partial transclusion tags because it often overrules the others. If there is at least one pair of "onlyinclude" tags on a page, then whenever this page is transcluded, it is only the material within the "onlyinclude" tags which gets transcluded. There can be several such sections, and within each such section, some material might be further excluded by "noinclude" tags, and might also be surrounded by "includeonly" tags so that it does not appear on the original page itself. But material outside the "onlyinclude" tags will be ignored when the page is transcluded onto another page. This can be useful, for example, to repeat a small part of one page on a second one: just surround the small part by onlyinclude tags, and transclude it onto the second page. Note that unlike and,  will take precedence over enclosing  tags. In other words, My content produces only "My content" when transcluded.

Subpages
You can cut and paste the text to be transcluded into a subpage, then use the name of the subpage in the transclusion template. This approach can be used only where subpages are enabled; for example, on the English Wikipedia, subpages can be used only from User, Talk or Wikipedia pages; currently, subpages cannot be created from main article pages.

Example: you want to discuss the deletion and redirecting of Pussycat to Cat. First, create the subpage Talk:Pussycat/Let's delete Pussycat!, write your comment into it, then transclude it in Talk:Pussycat and Talk:Cat using the template  . Comments posted in either talk page will be shown in both.

Special pages

 * See also:w:Wikipedia:Transclusion and 

Some pages on Special:Specialpages can be transcluded, such as Special:AllPages, Special:PrefixIndex, Special:NewFiles, Special:NewPages, Special:RecentChanges and Special:RecentChangesLinked.

Sample: gives 3 new pages.

URL parameters can be given like template parameters, e. g..

Alternatives to transclusion by template
Occasionally you may want to use a template, but for one reason or another may not want to use transclusion. The automatic one-time copying of a template's code/text to the location of a template tag is called Template substitution or subclusion (substitution + transclusion). To subclude a template's code/text, the template tag is modified from the standard transclusion tag to a substitution tag, simply by adding subst:, creating a tag with the form:.

Labeled Section Transclusion
An extension called Labeled Section Transclusion enables marked sections of text to be transcluded. An extension with a somewhat similar function is PageVariableExtension.

Semantic MediaWiki
The Semantic MediaWiki extension uses inline queries to query and display semantic data. There are currently two ways to perform transclusion or something similar: See inline queries for further information.
 * 1) Transclusion proper. The display format "embedded" ensures that selected pages (mainspace articles, templates, etc.) are transcluded. As with templates, sections placed between noinclude tags will be omitted.
 * 2) Selected passages in a page can be assigned a property of type 'Text'. These selections can be requested by running an inline query for this type of property.
