karaf shell each example

[Ba...@troika.ru]

Greetings!

Could you please help me write the karaf script which shows all feature 
names (only).
I tried the following:
  each (features:list) { echo ($it name) }
based on the example from mail list (it works!):
  each (bundles) { echo ($it symbolicname) }

But I got the error:
Error executing command: Argument values is required

Please, advice.

Regards,
Boris

L.S.,

There's some very basic information on the shell available on
http://karaf.apache.org/manual/latest-2.2.x/developers-guide/shell-syntax.html,
but it would definitely make sense to elaborate that page and add the
information about the exposed variables as well.  FWIW, I raised
https://issues.apache.org/jira/browse/KARAF-960 to track the improvement
request.

Regards,

Gert Vanthienen

Hello,

Guillaume could you give tips how to learn osgi / Karaf / ServiceMix shell
scripting?
>From what did you know or from what one should know that iterate object on
each is exposed in variable $it?
What are others already exposed variables like $.context?

Thank you in advance,
Mark

The 'bundles' call translates into bundleContext.getBundles() by virtue of
bundleContext being exposed implicitely and bundles being translated into
the getter call.
For features, you need to access the FeaturesService which is exposed in the
OSGi registry.

With karaf trunk, you could write something like :

fs = ($.context getService ($.context getServiceReference
org.apache.karaf.features.FeaturesService))
each ($fs listFeatures) { echo ($it name) }

Removing the $.context should make it work on your version.
