Dave Marion commented on ACCUMULO-1399:
---------------------------------------
Uploaded a patch so that folks can comment on what I am planning. To use, apply
the patch to trunk and build. Then, start up the shell and:
extensions -?
extensions -l # should show nothing
extensions -e # should show nothing
extensions -l # should show one extension name
help # should show a MyApp Extensions Command section
MyApp::debug # should print out "This is a test"
extensions -d # should show nothing
extensions -l # should show nothing
MyApp::debug # should tell you command doesn't exist
help # should not show MyApp command section
TODO: Need to add the commands to the shell completer
> Pluggable commands for the shell

> Proposing modification to the Shell to allow applications to create their own
> set of commands. This might be accomplished using java.util.ServiceLoader or
> something like it. Specifically, I'm thinking of a case where I have a create
> table command that is different than the one provided by the Shell. In my
> case, my create table command may create one or more tables and setup
> iterators on them.
