It's quite easy to do that with code, but I don't think we're
exposing that feature through the UI in any way right now. Would
be an interesting feature to add in the near term.

Hmm.. you could try to use export relations to prolog with
"smart query --format=prolog --show-all" and then do the query
with prolog, but that's for the brave. ;-)

Actually this is the equivalent of echo n | smart upgrade or echo n | smart install <pkg>. I guess this would be useful in the query command.

Mandriva urpmq provides the following options:

--requires
           Prints the package requires.

--requires-recursive
           Print dependencies (maximal closure).

--whatprovides
           Search in provides to find package.

--whatrequires-recursive
           Reverse search to what requires recursively the package given
           (looking through virtual packages).

It would be very useful for smart to provide the equivalent. It currently provides:

--show-provides Show provides for the given packages
--show-requires Show requires for the given packages

It would should also provide:

--show-provides-recursive
--show-requires-recursive

this would be particularly useful with the dotty output for visualizing loops in dependencies etc:

smart query --format=dotty --show-requires-recursive basesystem-minimal
