[jira] Commented: (FELIX-2536) Gogo Shell should export org.apache.felix.gogo.options package

["Richard S. Hall (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-2536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12897267#action_12897267 ] 

Richard S. Hall commented on FELIX-2536:
----------------------------------------

I don't think something like this will become part of the spec. We are free to include it, but it would tie such commands to our shell impl. It appears that the RFC is going to include annotations similar to the ones introduced in Gogo when I created the commands in the the "command" Gogo sub-module.

>         System.out.println("directories=" + opt.get("directories"));
> However the package containing this class is not exported from this bundle so it cannot be used by client code
