The PdfBook extension composes a book from pages in a category and exports them as a PDF file.

Overview

Categories are a good way of organizing many articles comprising a book. One can use the sort keys in the "pages" categorization statements to ensure they are correctly ordered. This extension allows such categories to be compiled into downloadable PDF files with a table of contents, each page forming the start of a new chapter.

Usage

The PDF creation is initialized by the "pdfbook" action, so a category can be downloaded as a PDF book directly from a link such as:

https://www.example.org/wiki/index.php?title=Category:foo&action=pdfbook

A more generic way of creating the link is to use the "fullurl" parser function and {{FULLPAGENAME}} variable as in the following example:

[{{fullurl:{{FULLPAGENAME}}|action=pdfbook}} download this selection of pages as a PDF book]

This link can then be added to a template which can be transcluded into any category or page suitable for downloading as a book. For an example of such a template, see OrganicDesign:Category:I am that, which uses OrganicDesign:Template:Book to display the message and download link.

In order to include this parser function link automatically to every category page, add it to the Mediawiki:Category-article-count page.

This extension also allows books to be generated from non-category pages as well. If the page to be downloaded as a book is not a category, then the extension will extract the titles from page links in a bullet list. The list may be explicitly defined or may be the result of a query. For an example of this functionality, see Creating a PDF book from a DPL query

Raw HTML output

You can download the file as a single HTML document by setting format=html in the query-string. Example:

https://www.example.org/wiki/index.php?title=Main_Page&action=pdfbook&format=html

Single page exports

You can export a single page as a one-page PDF by setting format=single in the query-string. Example:

https://www.example.org/wiki/index.php?title=Main_Page&action=pdfbook&format=single

Page Breaks

You can add page breaks into your book by adding <!-- PAGE BREAK --> into the relevant places in the content pages.
