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 - current source format:
    • for Gnome's Yelp (+ .OMF for its catalog rarian, but only up to yelp version 2.23 [IRC log]),
  • HTML - currently processed by gdp:2002 stylesheets
    • plain for MacOs's browser,
    • compiled for Windows help viewer,
    • plain for KDE's Khelpcenter (+ .desktop for its catalog) - currently not implemented.

Additional supported are for offline reading - processed by standard stylesheets:

  • PDF
  • Mobi
  • ePub

Currently used templates

Documents

Current Source files have a marker
<!--
      (Do not remove this comment block.)
  Template Maintained by the GNOME Documentation Project:
	  http://developer.gnome.org/projects/gdp
  Template version: 2.0 beta
  Template last modified Feb 12, 2002
-->

XSL etc.

According the XSL Changelog it is a slightly adjusted copy of gdp's xsl from 2003. That is the reason some formats of the docs still look like GNOME1.

The architecture of the build system seems to date back to the same roots.

Fell (talk) considers replacement by it's GNOME2 successor Gnome Doc Utils, which was maintained until 2012.

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

Additional there are .png images in stylesheets, copied from (an old version of) docbook-xslt/images. We should consider an update.

xsl/README suggests to verify, that

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

Catalogs

Catalogs hold meta information for faster access.

OMF

Our omf.make has in its header
#	This file was taken from scrollkeeper_example2, a package illustrating
#	how to install documentation and OMF files for use with ScrollKeeper
#	0.3.x and 0.4.x.  For more information, see:
#		http://scrollkeeper.sourceforge.net/	
# 	Version: 0.1.2 (last updated: March 20, 2002)

GDU would have replaced this template by extracting special tags. This was never applied by us. As said before, it is no longer used by yelp, but it is unknown if they have a replcement.

desktop file

KDE's Helpcenter would use a XDG desktop file for metainformation. Eventualy a desktop file could be used in other places, too.

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
