Gogo could align its parameter help better
------------------------------------------
Key: FELIX-3215
URL: https://issues.apache.org/jira/browse/FELIX-3215
Project: Felix
Issue Type: Improvement
Reporter: Glyn Normington
Priority: Trivial
In implementing Virgo bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=350853,
I ran into this issue.
The following is the desired output:
osgi> help vsh:bundle
bundle - examine or manage a bundle artifact
scope: vsh
parameters:
String operation (examine|diag|headers|start|stop|refresh|uninstall)
long bundle id
...
Note that "operation" and "bundle id" are aligned even though "String" and
"long" are not the same length. To achiever this, I had to code extra spaces in
the descriptor for bundle id as follows:
@Descriptor("examine or manage a bundle artifact")
public void bundle(@Descriptor("operation
(examine|diag|headers|start|stop|refresh|uninstall)") String op,
@Descriptor(" bundle id") long bundleId) {
doBundle(op, String.valueOf(bundleId));
}
It would be helpful if Gogo handled this alignment automatically. In
particular, it would make the using code easier to maintain.
Note that this bug has priority trivial, but would be a good one for a beginner
to have a go at fixing.
