Wikinews:Assistant:View intersection/doc

This assistant displays a scrollable list of articles belonging to an intersection of categories. Primary access is through template undefined, allowing the creation of wikilinks to display category-intersections without requiring the construction of a specialized wiki page for each such intersection desired.

Access: viewable.

Inputs:
 * &mdash; a category articles must belong to.
 * &mdash; a second category articles must belong to (except as below).
 * &mdash; a third category articles must belong to (except as below).
 * &mdash; if non-blank, articles must not belong to.
 * &mdash; if non-blank, articles must not belong to.
 * &mdash; if, only list unpublished articles; if  , list both unpublished and published articles; otherwise (such as if blank), list only published articles.

Function:
 * Ordinarily &mdash;if no more than the first three parameters are used&mdash; lists published articles belonging to the intersection of the named categories. The second and third parameters can be inverted, to list only articles that don't belong to those categories instead of articles that do.  An additional parameter can change the handling of published versus unpublished articles. Allows scrolling through the list, similarly to topic cat; for which purpose, internally uses parameters   and.
