Best practice for multi-argument karaf commands

[Васил Зорев <va...@gmail.com>]

Hello,

I am looking into the possibility of a Karaf command which can take a
bigger number of arguments (probably 10 or more).

The closest use case I can give is a map of key-value pairs (or
properties?). Something like ID1=val1, ID2=val2 etc. where each ID is a
String value. The main argument for a map (vs List) is that the IDs
represent different entity types, so I cannot treat them the same way.

I saw in org.apache.karaf.shell.support.converter.DefaultConverter there is
a possibility to convert maps. However in
the org.apache.karaf.shell.api.action.Argument
and org.apache.karaf.shell.api.action.Option API, the multiValued attribute
says it expects a list.

Can this be done with a org.apache.karaf.shell.api.console.Parser ?

Do you think it is a good idea at all in the context of command-line
operations or would you recommend another approach ?

Thank you,
Regards,
Vassil

Thanks, I think this fits the use case as well :) and is probably more
structured than the system properties.

Well, another option is to pass some sort of config or arguments file
with structured data (JSON, YAML, XML) and give that in the command
(--config <path-to-file>)

The point is there are multiple commands and one command produces these IDs
as a result of its execution which are then needed by the other commands
for their own execution. Honestly I'm leaning more toward system properties
as this is a test environment anyway, doesn't have to be perfectly
designed...

Still, if you have recommendations, please let me know.

btw doesn't have to be arguments specifically. Can be options as well,
similar to the git style: git -c name1=value1 -c name2=value2 etc.
