Extension:PdfBook

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

Overview
Categories are a good way of organizing many articles which together comprise a kind of book. The sort-keys in the 'articles' categorization statements can be used to ensure that they are ordered properly. This extension allows such categories to be compiled into downloadable PDF files with a table of contents, each article forming the start of a new chapter.

In version 0.0.5, a new feature has been added which allows books to be generated from non-category pages as well. If the article to be downloaded as a book is not a category, then the extension will extract the titles from article 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

Since version 1.0.1, PdfBook can also export single articles by using format=single in the URL

Installation
Htmldoc needs to be installed.
 * Pre-requisite
 * On Debian based systems such as Ubuntu or Mint use: apt-get install htmldoc.
 * On Windows compile or install HTMLDOC and add HTMLDOC to the PATH. Binaries can be found here (paehl.com).
 * On Mac OS X: Downloading from source, using the common "./configure; make; sudo make install" procedure" works if you have those developer tools installed.

If you're using a version of MediaWiki prior to 1.25, please use the MediaWiki-1.24 branch instead of the master branch to download PdfBook.


 * Extension

I've noticed that MediaWiki requires more memory to create large books. If your book is around a hundred articles you'll need to give PHP 64MB.

Usage
The PDF creation is initialised by the pdfbook action, so a category can be downloaded as a PDF book directly from a link such as: http://www.foo.bar/wiki/index.php?title=Category:foo&action=pdfbook

A more generic way of creating the link is to use the "fullurl" parser function and the FULLPAGENAME built in variable as in the following example. [ download this selection of articles as a PDF book] This link can then be added to a template which can be transcluded into any category or article 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:Categoryarticlecount page.

Raw HTML output
You can download the file as a single HTML document by setting format=html in the query-string. Example: http://www.foo.bar/wiki/index.php?title=Main_Page&action=pdfbook&format=html

Single page exports
You can export a single article as a one-page PDF by setting format=single in the query-string. Example: http://www.foo.bar/wiki/index.php?title=Main_Page&action=pdfbook&format=single

Page Breaks
You can add page breaks into your book by adding  into the relevant places in the content articles.

While using action=pdfbook&format=html to create an printable HTML from an category it seems not to work Use eg End of the document  to create the page-break

Configuration
Here are some global variables which affect the operation of the extension. These should be set in your LocalSettings file after the include of the PdfBook.php script. These configuration options can be overridden by the parser function so that they can be set specifically for each book.

Bugs and Todo
Please see the GitHub issue tracker to view or report bugs.


 * Kindly update the "Usage" section with a step by step guide of how to implement the sidebar link for the vector theme.
 * Multibyte characters not working
 * Tables are "hardwired" to a standard format currently
 * Dynamic per-book parameters not done yet
 * Interference with Extension:ASHighlight: Export halts on first encountered tag. Use Extension:SyntaxHighlight GeSHi instead.
 * If pdfbook is generated from an article containing article links in a bullet list, all articles in the pdf have the title of the first article in the list, not their own.
 * Solution: change the line 122 of PdfBook.php to this: "$wgOut->setHTMLTitle( $ttext, true );  # use this so DISPLAYTITLE magic works"
