-----------------------------------------
You're welcome. I remember that during a face to face meeting, Xander and I
discussed some other possible extensions he had as well. I'm sure he has some
feedback on this as well. :)
> Dependency Manager Shell improvements
> -------------------------------------
>
> Key: FELIX-4294
> URL: https://issues.apache.org/jira/browse/FELIX-4294
> Project: Felix
> Issue Type: Improvement
> Components: Dependency Manager
> Affects Versions: dependencymanager-3.1.0
> Reporter: Pierre De Rop
> Assignee: Pierre De Rop
> Priority: Minor
>
> This issue proposes two enhancements regarding the dependency manager shell.
> 1) display component names more consistently
> =====================================
> - some components are sometimes displayed with a "class " prefix, while
> others are not:
> class org.amdatu.multitenant.adapter.TenantAdapter registered
> org.amdatu.multitenant.adapter.BundleDataStore(org.amdatu.tenant.pid=org.amdatu.tenant.PLATFORM,bundle.id=18)
> registered
> For readability, the "class " could be just removed.
> - When a component does not contain any service properties, an empty "()" is
> displayed after the component name
> pierre.multitenant.both.Both() registered
> org.amdatu.multitenant.TenantLifeCycleListener(org.amdatu.tenant.binding=3)
> registered
> As in previous case and for readability, it makes sense to not append an
> empty "()" after the component name, if it has no properties.
> 2) add "filter" and "nofilters" options for filter displayed components
> =====================================================
> By default, the "dm" shell command dumps all components. But sometimes, it
> is desirable to display a subset of all components,
> using a regular expression on the component name or on the component service
> properties.
> We can of course do this using gogo shell "grep", but the problem is that we
> may miss some important informations, like the component bundle id, or the
> component dependencies.
> As an example, let's assume we are using the AMDATU mutli-tenancy framework.
> With AMDATU MT, many internal AMDATU components are instantiated behind the
> scene for a given tenant bundle.
> In the following example, we have three tenant bundles, and if we type "dm",
> then we are getting a long list of components, including:
> - application tenant components: pierre.multitenant.*
> - some internal amdatu mt components (org.amdatu.multitenant.*):
> g! dm
