[Refdb-users] Add capability for FOP user configuration file

[David N. <dav...@sw...>]

Markus,

I've been figuring out how to add fonts to FOP and XEP (specifically, 
TeX's default font of Computer Modern).

Adding fonts to FOP requires the creation of a user configuration file 
which is passed to FOP at execution time as a command line parameter.  
[For more information, see 
<http://xml.apache.org/fop/configuration.html> (the fop configuration 
file) and <http://www.sagehill.net/docbookxsl/AddFont.html> (adding 
fonts to fop and xep).]

Adding support to refdb for FOP's configuration file requires four minor 
tweaks to the refdbxml and refdbxmlrc files:

1. Add the following lines to refdbxmlrc (I put them just after the FO 
Classpath section).
................................................................................
## FOP configuration file (optional)
#fop_config_file
................................................................................
You may want to add a sample configuration file for illustrative purposes:
................................................................................
## FOP configuration file (optional)
#fop_config_file /home/user/fop/cfg.xml
................................................................................


A few small alterations are made to refdbxml.

2. Initialise variable 'fop_config_file' and set to an empty string.  
This is not really necessary but follows the script's pattern.  I added 
them around line 40 (just after <<fo_classpath="">>).
................................................................................
# FOP can accept a user configuration file parameter
fop_config_file=""
................................................................................

3. The value must be extracted from the config file.  Add the following 
to the various 'if' statements around line 80.
................................................................................
            if [ $refdbvar = fop_config_file ]; then
                fop_config_file="-c $refdbval"
            fi
................................................................................

4. Finally, add the 'fop_config_file' variable to the FOP execution 
command.  No conditionals are needed -- if the user did not specify a 
config file the variable is empty and makes no difference.  If the 
previous alterations have been made, this command is on or about line 188.
................................................................................
                java -cp "$fo_classpath" org.apache.fop.apps.Fop 
$fop_config_file -fo $1 -pdf $2;;
................................................................................

Regards,
David.
