Several enhancements have been made to the latest version of xddgen:
Generate an XDD for EXTERNAL files
Support was added xddgen to generate an XDD for files defined as EXTERNAL. By default, xddgen does not generate XDD files for external files, but it is now possible to change the xddgen configuration file follows to instruct xddgen to generate XDD files for EXTERNAL files:
# If yes, generates xdd file also for "external files"
# Value: 'yes', 'no'
consider-external-file: yes
Now when an external file is ignored, xddgen generates a warning message to inform about it.
Key based on a redefine
The xddgen utility used to return an error if a key was based on a redefine of a field or, in case of split keys, if one of the specified fields was a redefine. Now the logic has been changed to allow these conditions and produce a warning indicating the situation.
It is possible to change the behavior from the default of generating a warning to the old behavior of getting an error (or even to allow it without any warning) by changing the xddgen configuration entry:
# behaviour when a key is based on a redefine of a field.
# Value: 'ok', 'error', 'warning'
key-on-redefines: warning
Rationalized xddgen behavior on error
If an error occurs while generating an XDD, the XDD will not be generated (although other XDDs may be generated). The xddgen utility will always return a value different than 0 on the occurrence of an error. This implies it is sufficient to check the return code to see if something failed during xddgen execution.
