ਫਰਮਾ:Shelves
ਫਰਮਾ:Possible-risk This template categorizes a book on one or more shelves in the Wikibooks Stacks, plus the book category.
Usage[ਸੋਧੋ]
Use this template only on the book's main page. Specify the names of the shelves as unnamed parameters, such as {{shelves|mathematics|science|etc}}.
For non-shelf categories, such as descendants of Category:Books by type, use template {{categories}}.
On subpages of a book, use {{BookCat}}.
Internals[ਸੋਧੋ]
This template is responsible for adding books to the hidden allbooks categories, which allow automatic generation of lists of books belonging either to a given shelf or to any of its sub-shelves. When this template detects that it is being used on the main page of a book, for each shelf specified it calls {{shelves/leaf}}, via Module:TScope#map. This is why this template should only be used for shelf categories: {{shelves/leaf}} uses shelf pages to figure out which allbooks categories to add the book to, and if there are no shelf pages to consult, it reports the problem to Category:Book:Wikibooks Stacks/Attention needed. By using {{categories}} for non-subject categories, one avoids nuisance reports to Category:Book:Wikibooks Stacks/Attention needed.
The book is also added to hidden Category:Book:Wikibooks Stacks/Books; and, if no shelves are specified, to Category:Book:Wikibooks Stacks/Books/Unshelved.
If the template detects that it was called on a page that isn't the main page of a book, it does nothing.
This template can be induced to display diagnostic messages, explaining why it has put the page in Category:Book:Wikibooks Stacks/Attention needed, by specifying parameter diagnose=true.
