The output rendering done by dblatex can be widely
customized like explained in Chapter 4, Customization. By default several
rendering styles are provided, that one can choose by using the option
-T (see Example 3.1, “Choosing the DB2LaTeX style”). The available styles are:
The rendering uses the default LaTeX stylesheets. It is the style used by
default if dblatex has been configured without using the option
--style.
The rendering is very close to original latex rendering. The wrapper around the default latex packages is very thin.
The rendering tries to be as close as possible to the DB2LaTeX formatting.
The rendering style stuff is under the latex/
directory. You can see the XSL stylesheets under xsl/ as the
way to produce latex with as little as possible docbook specific things (even if a
large amount of latex packages are used to do the work). Then, it's up to LaTeX
stylesheets to format the document as you wish.
The organization under latex/ is as follow:
contribContains the non-default available LaTeX stylesheets (simple and db2latex).
graphicsDefault graphics used in the admonitions (e.g. warning).
These graphics are used by the default output formatting.
scriptsScripts used to compile with latex or pdflatex.
specsContains all the configuration files describing the available styles.
A specification file must have the extension .specs, .conf, or .xml to be
detected as a style description, and its basename is the name of the style.
For example the style db2latex is described by the configuration file
db2latex.xml.
When dblatex is executed with no parameter, the usage is displayed. In particular, the list of the available styles is given, like this:
$ dblatex
dblatex [options] file.{sgml|xml}
Options:
-t {pdf|ps|dvi|tex|xml}: output format
...
-T style : available latex styles (db2latex, native, simple)
The list is built by scanning the specs files found under
specs/. The spec file syntax is described in the section called “Dblatex Configuration File”.
styleDefault LaTeX stylesheets.
To add a new formatting style, do the following steps:
Let's create the style directores that will contain all the specific data. We choose to put them under the default dblatex user configuration directory.
$ mkdir -p $HOME/.dblatex/mystyle/latex $ mkdir -p $HOME/.dblatex/mystyle/xsl
Note that you could choose another configuration directory (see the section called “Configuration Paths” for more details).
Create the latex stylesheets you need. It must define the expected DocBook interface and include some core definitions from the default latex stylesheets (cf. the section called “Customized LaTeX style”). Create also your XSL stylesheet if necessary.
Put these files under the appropriate directories:
$ mv mytexstyle.sty $HOME/.dblatex/mystyle/latex/. $ mv param.xsl $HOME/.dblatex/mystyle/xsl/.
Create a configuration file under the directory
$HOME/.dblatex. The configuration file must point to the
new latex stylesheet, and give the specific parameters. Example:
$ cat $HOME/.dblatex/mystyle.conf
<?xml version="1.0" encoding="utf-8"?>
<!-- =======================================================
Dblatex config file for my new style.
Note that the directories are relative to mystyle.conf
======================================================= -->
<config xmlns="http://dblatex.sourceforge.net/config">
<latex>
<texinputs>mystyle/latex//</texinputs>
<texstyle use="mytexstyle"/>
</latex>
<xslt>
<stylesheet fileref="mystyle/xsl/param.xsl"/>
</xslt>
<options>-f fig</options>
</config>
That's it. Try to compile your document with your style, and check the output.
$ dblatex -T mystyle file.xml
