There is currently nothing available for the latest MediaWiki that allows you to easily create a collection of articles and produce a PDF "book" from that list of articles.
The existing Collection extension provides users with a UI to pick individual pages and put them into a book, or collection of pages, that they can share with others. In the past, the collection extension could use PediaPress's mwlib to produce a PDF. The mwlib functionality is no longer available or maintained.
Meanwhile, DocBookExport allows you to produce a single PDF from a group of articles. It also allows the end user to provide a list of parameters that change how the PDF looks. From the extension's page, you can see that at least these options are available:
- title (e.g. My Guide to Bowling)
- cover page
- index term categories
- index terms
- size (e.g. A4)
- font size
(The above list could probably be normalized, but that isn't the point here.)
This task proposes combining the PDF-creation functionality of DocBookExport with the collection creation of the Collection extension to provide end users with a way to produce PDF's from a list of pages.
