>                 URL: https://issues.apache.org/jira/browse/FELIX-5770
>             Project: Felix
>          Issue Type: Improvement
>          Components: Declarative Services (SCR)
>    Affects Versions: scr-2.0.14
>            Reporter: Neil Bartlett

> The scr:list and scr:info commands are hard to use and not as extensible as they could be.
> In terms of usability, the output of scr:list is particularly hard to follow, with two interleaved tables at different indent levels, i.e.:
> {noformat}
> g!  scr:list
> BundleId Component Name Default State
>     Component Id State      PIDs (Factory PID)
> [   1]   com.effectiveosgi.rt.aws.impl.S3ObjectConverter  enabled
>     [   0] [active      ]
> [   1]   com.effectiveosgi.rt.aws.s3  enabled
> {noformat}
> It is not very clear what the numbers 0 and 1 represent in each case!
> Also the commands format their output internally, which does not allow the formatting to be reused. If the commands simply return DTO objects to the Gogo shell and then implement a Converter service to format them, then the formatting can be reused by other commands.
> Also the state "SATISFIED" is very confusing when a component throws an exception in its activator. This is partly a problem with the OSGi spec pre-R7.
> The release of OSGi R7 gives us an opportunity to overhaul these commands and improve the formatting. For a proposed reimplementation see https://github.com/apache/felix/pull/130
