The DocBookExport extension lets you create a DocBook from selected wiki pages. You can download the DocBook as an XML file. Other formats supported are ODT, HTML and PDF.

Installation

Make sure that you installed all required dependencies on your server.
  • Download and move the extracted DocBookExport folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/DocBookExport
  • Add the following code at the bottom of your LocalSettings.php file: 
    wfLoadExtension( 'DocBookExport' );
  • Configure as required
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

$wgDocbookExportPandocServerPath
The URL for the html_to_docbook script on its server, e.g. http://example.com/html_to_docbook
$wgDocbookDownloadServerPath
The URL for the directory in which generated files will be placed.
$wgDocBookExportImportXSLRepoPathPDF
The path to a git repo for pulling the XSL files from.
$wgDocBookExportXSLRepository
The path of the XSL file to be used for DocBook generation.


Dependencies

On the wiki, install the Figures extension, which supports defining figures in MediaWiki.

On either the wiki's server, or any other server, install the following: 

sudo wget github.com/jgm/pandoc/releases/download/2.16.2/pandoc-2.16.2-1-amd64.deb
sudo dpkg -i pandoc-2.16.2-1-amd64.deb

For HTML output

To download the output as an HTML file, install the following, on the same server that holds html_to_docbook:

  • xlstproc: for Ubunutu, install using:
sudo apt install xsltproc

For PDF output

To download the output in PDF format, install the following software, on the same server that holds html_to_docbook: 

sudo apt-get install fop

For Zip output

To download DocBook files in Zip format, install the following, on the same server that holds html_to_docbook:

  • ZipArchive PHP extension: if it's not already within your PHP installation, you can install it in Ubuntu using:
sudo apt-get install php7.0-zip
service apache2 restart

Usage

To create a book, first define the page structure using the #docbook parser function. Here is an example call: 

{{#docbook:
page structure=
? Bowling Introduction
+ Intro Chapters
* How I buy shoes(orientation=landscape)
* Testing page
** Buying clothes intro,Buying shoes(title=Buying the right clothes,header=section header,header_left=section left header)
? Appendix
|title=My Guide to Bowling
|productname=MY PRODUCT NAME(class=trade)
|corpauthor=Wikiworks
|biblioid=MY Bibliod(class=pubnumber)
|volumenum=1
|revhistory=13.1,24 June 2020
|keywordset=KEYWORD1,KEYWORD2
|subjectset=DO NOT REMOVE
|subtitle=Edition M Version 1
|cover page=Cover Contents
|header=My Guide to Bowling
|footer=My Guide to Bowling
|header_left=My Guide to Bowling Left
|footer_left=My Guide to Bowling Left
|header_right=My Guide to Bowling Right
|footer_right=My Guide to Bowling Right
|index=1
|index term categories=index terms(group by=Index has Group)
|index terms=shoe,clothes
|orientation=portrait
|section_autolabel_max_depth=6
|external_link_color=green
|size=A4
|columns=1
|timestamp=1
|watermark.text=DRAFT
|watermark.rotation=-45 deg
|watermark.color=#f2f2f2
|watermark.font.family=Sans
|watermark.font.size=12pt
|title.font.family=Helvetica 
|body.font.family=Times Roman 
|body.font.size=12pt
|footnote.font.family=Times Roman 
|footnote.font.size=8pt
|margin-inner=0.5in
|margin-outer=0.5in
|margin-top=0.5in
|margin-bottom=0.5in
|xsl_import_path=/var/www/html/mycustomxsl
}}

On saving the page, a link will be generated which directs you to a special page Special:GetDocbook. The request is then pushed to the server handling HTML-to-DocBook generation. Once the DocBook is generated, links will be made available on the Special page to download the DocBook: in XML, HTML, ODT and PDF formats.

The parameters shown can be customized as follows:

  • page structure is used to define the wiki pages that will be part of the DocBook as cover, sections and chapters. The first line starts with a '?' and indicates the preface, + indicates a page which contains multiple chapters, each chapter is specified using a h1 heading. * indicates a chapter and ** indicates a section of that chapter. Sub-sections can be defined using *** or **** and so on. The last line again starts with a '?' and indicates the wiki page to be used as the appendix. Sometimes you may want to merge contents of multiple wiki pages to one section/chapter. For that you can add a comma separated list of such pages as well. You can also customize the title of such a section by adding the following wikitext (title=) at the end of the line. Similarly you can customize the header/footer/header left and right/footer left and right for a specific section by using the (header=) syntax at the end of the line as shown in the example. To change the orientation of a specific chapter or section add (orientation=landscape)
  • title This parameter defines the name of the DocBook. This doesn't relate to any wiki page and is only used to name the files and the title of the docbook.
  • cover page This parameter specifies the wiki page to be used as the cover page.
  • headerThis parameter specifies the header to be used for every page of the docbook.
  • footerThis parameter specifies the footer to be used for every page of the docbook.
  • header_leftThis parameter specifies the header on the left side of the page to be used for every page of the docbook.
  • footer_leftThis parameter specifies the footer on the left side of the page to be used for every page of the docbook.
  • header_rightThis parameter specifies the header on the right side of the page to be used for every page of the docbook.
  • footer_rightThis parameter specifies the footer on the right side of the page to be used for every page of the docbook.
  • indexThis parameter should be set to 1 in order to generate the index.
  • index terms This parameter is a comma separated list of terms that should be indexed.
  • index term categories If you have wiki pages for all your index terms you can add them to a category and mention it here.
  • orientation Lets you customize the orientation of the output format.
  • section_autolabel_max_depth Lets you set the parameter section.autolabel.max.depth in Docbook.
  • external_link_color Lets you set the color for external links for PDF.
  • size Lets you customize the size of the page.
  • column Lets you customize the number of columns.
  • margin-* Lets you customize the margin for each side of the page.
  • timestamp=1 Adds a timestamp on the bottom-right part of the cover page with the following text: Produced from <wiki URL> on <timestamp>.
  • title.font.family=Helvetica Lets you customize the font for the title of the PDF.
  • body.font.family=Times Roman Lets you customize the font for the body of the PDF.
  • body.font.size=12pt Lets you customize the font size for the body of the PDF. The font size for the footnotes would be 0.8 times this size.
  • footnote.font.family=Times Roman Lets you customize the font family for footnote.
  • footnote.font.size=8pt Lets you customize the font size for the footnote of the PDF.
  • watermark.text=DRAFT Lets you add a watermark in the PDF. Watermark is a text used as a SVG image with additional options for styling the text.
  • watermark.font.size=8px Lets you customize the font size on the watermark in the PDF.
  • watermark.font.family=Sans Lets you customize the font on the watermark in the PDF.
  • watermark.rotation=-45 deg Lets you rotate the text on the watermark in the PDF.
  • watermark.color=#f2f2f2 Lets you customize the font color on the watermark in the PDF.
  • xsl_import̜_path=/var/www/html/mycustomxsl Lets you provide your custom XSL configuration files. This path would be replaced in the "DOCBOOKXSLPLACEHOLDER" path in the xsl template file instead of the standard docbook xsl files.
  • All other parameters are self-explanatory DocBook element tags.

DocBook supports figures which are images or other media that can be referenced elsewhere in the document. A separate list of figures is also prepared. To define a figure you need to use the Figures extension.

Grouping of indexes is possible as well. To use this feature add the following wikitext to the index term page (create if required) specifying the group name: 

{{#docbook_index:grouping=Group_name}}

Another approach to add grouping is by specifying a Semantic MediaWiki property which contains the group name, this can only be done for index term categories and can be specified using "group by" parameter as follows:

|index term categories=index terms(group by=Index has Group)

While styling in wiki pages is easy using CSS, the same styling is not carried forward to the DocBook. This can be a problem with tables which sometimes should have different widths for different columns. To solve this you can specify a class with the following format: colwidth-80-20, the extension will then convert it to the following DocBook XML which ensures that the column width is maintained in the DocBook: 

    <colspec colwidth="80*" align="left"/>
    <colspec colwidth="20*" align="left"/>

Similarly, for a three-column table specify the class as "colwidth-80-10-10".

Process diagram

The following diagram shows how the various software and utilities are used together to create the different output formats that DocBookExport supports, and hopefully makes it easier to understand which dependencies are needed for which outputs. Note that docbook2odf comes pre-bundled with the html_to_docbook library; the rest would need to be installed individually, if they are not already on your system.
