Raymond Augé commented on FELIX-5970:
-------------------------------------
I've implemented it slightly differently. There's a gogo specific namespace
called {{org.apache.felix.gogo}} and it is used to resolve the Gogo _love
triangle_ (runtime, shell impl, command.)
A third party uses the requirement like so:
{code:java}
// for `org.apache.felix.gogo.shell`
Require-Capability:
org.apache.felix.gogo;filter:="(&(org.apache.felix.gogo=shell.implementation)(implementation.name=gogo.shell))"
// for `org.apache.felix.gogo.jline`
Require-Capability:
org.apache.felix.gogo;filter:="(&(org.apache.felix.gogo=shell.implementation)(implementation.name=gogo.jline))"{code}
However, the simpler way to use it is with the {{@Retention(CLASS)}} annotation
{code:java}
@org.apache.felix.service.command.annotation.RequireGogo{code}
With this annotation you can choose which shell impl you want:
{code:java}
// for `org.apache.felix.gogo.shell`
@RequireGogo
OR
@RequireGogo(RequireGogo.SHELL)
// for `org.apache.felix.gogo.jline`
@RequireGogo(RequireGogo.JLINE){code}
The annotation is
{code:java}
@Target({TYPE, PACKAGE}{code}
> Add requirement & capabilities model so gogo can be resolved
