The Docbook based Gnucash documentation makes use of several components to produce the different output forms. See also the README file.

Supported Output formats

Our primary target is the context sensitive help F1 for the program. It's format is OS dependent:

• Docbook for Gnome's Yelp
• HTML
  • plain for MacOs's browser
  • compiled for Windows help viewer.

Additional supported are for offline reading:

• PDF
• Mobi
• ePub

Fell (talk) considers replacement by Gnome Doc Utils.

Processing

XML

The processing is done by Extensible Stylesheet Language Transformations (XSLT), where xsltproc applies on the elements of the source XML file the instructions of the respective XSL file.

For that reason the repository contains in the xsl directory

• a copy of docbook-xsl, currently 2017 in version 1.75.2 in a respective named subdirectory and
• in the directory itself that of the GNOME Documentation Project as customization layers. They expect at least DocBook XML 4.1.2, which requires at least docbook-xsl-1.45

xsl/README suggests to verify,

xmlcatalog /etc/xml/catalog  http://docbook.sourceforge.net/release/xsl/current/html/chunk.xsl

returns a local path. If not read xmlsoft.org's Catalog support and run the script from DocBook

After you installed docbook-xsl locally, you should have its reference documentation under file:///usr/share/doc/packages/docbook-xsl-stylesheets/html/index.html. For the HowTo see Bob Stayton's DocBook XSL: The Complete Guide.

Because we use a standard xsl package we should not adjust them or we had to track our patches. Instead we can use a CSS

Alternatives to docbook-xslt

by yelp

Yelp offers its own tools and stylesheets [1], which are significant smaller: file:///usr/share/yelp-xsl/xslt.

yelp-build can process

• from: Mallard, DocBook, man, info, and HTML documents
• to: HTML, EPUB, ...

It might be useful to run sometimes yelp-check to verify the compatibility.

by GDU

is based on the usually make and has his own xslts, too: file:///usr/share/xml/gnome/xslt
