Template:BookCat/doc
Template:Documentation subpage Template:Possible-risk
This template puts the page on which it's used ({{FULLPAGENAME}}) into appropriate categories, based on certain page-naming and page-categorization conventions.
Usage
When used without parameters, it
- places subpages of a book in the book's category (Template:Nowrap) and sorts them by chapter name.
- places a book's templates in the book's template category (Template:Nowrap). This only does the right thing if a book's templates begin with Template:Nowrap .
- places a book's template category in the book's category and in Template:Nowrap .
- places any other category in its parent, sorted by the category's last name. The parent has the same name except removing everything from the last slash on; and the last name is the part that was removed after that last slash. For example, Template:Nowrap would go in Template:Nowrap with sort key
Images.
Parameters
Optional parameter Template:Nowrap changes the behavior on book pages, so that a book page with more than one slash in its name is placed in a subcategory of the category where its parent page would be placed, sorted by the page's last name. For example, using Template:Nowrap on page Template:Nowrap would put that page in Template:Nowrap with sort key Asia .
Optional parameter Template:Nowrap changes the behavior on template pages to deep filing (so Template:Nowrap would go in Template:Nowrap).
Optional parameter sort or sortkey specifies a sort key to be used for categorization instead of relying on Template:Tl.
Optional first unnamed parameter is a full page name to use instead of the {{FULLPAGENAME}} of the current page.
An alternative template Template:Tl reports the output of Template:Tl (with or without parameters) as an inert string, rather than categorizing the current page.

Internals
This template itself only contains the logic to sort out the identity of the target page; deducing the appropriate categorization is then delegated to Template:Tl. As of this writing, parameters assembled here are namespace, pagename, fullpagename, and sortkey; the first unnamed parameter is removed, and all other parameters are passed through to the subtemplate.
