Add ability for various Packager plugins to report their "options" via command
line
-----------------------------------------------------------------------------------
Key: DS-387
URL: http://jira.dspace.org/jira/browse/DS-387
Project: DSpace 1.x
Issue Type: Improvement
Components: DSpace API
Affects Versions: 1.5.2, 1.6.0
Environment: Any command line interface
Reporter: Tim Donohue
Priority: Minor
Attachments: PackagerOptions.patch
Currently, the various packager plugins (METS & PDF) have no way to report to
users what options are available to be passed to the plugin (via the 'packager
-o [option]=[value]' flag).
It'd be nice to allow a user to get a brief description of the valid options
for each plugin via the commandline interface. I've implemented a simple patch
(see attached) which lets users do this as follows:
(1) running 'dspace packager -h' will output the normal Help information,
including a list of all currently configured packager plugins (this feature
already existed)
(2) running 'dspace packager -h -t METS' will report normal Help information,
but will *also* output some additional options which are specific to the METS
packager plugin. Similarly, 'dspace packager -h -t PDF' would report any
additional options which are specific to the PDF packager plugin.
The way this is implemented is to add a "getParameterHelp()" method to both the
PackageIngester and PackageDisseminator interfaces. Each implementing packager
plugin is responsible for reporting any custom options in this
"getParameterHelp()" method.
See the attached patch for further details. (NOTE: This patch is very
slightly dependent on DS-386 in that some of the line numbers in the patch are
only correct if you already have installed DS-386.)
