I have put the initial prototype (does what provides) here: https://github.com/openSUSE/zpm The design we found would allow for one type of iterator for various queries that are completely different in libzypp: like whatprovides or getupdates. This iterator can easily be wrapped in each script language into something like you describe above. The README example works already: > ./what_provides apache2 2.2.17-3.1 (queries for http_daemon) Lets see if I find time to add something like getting updates (more complicated, ZYpp can ask for keys on refresh and stuff) and then wrap it in ruby. -- Duncan Mac-Vicar P. - http://www.suse.com/ SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) Maxfeldstraße 5, 90409 Nürnberg, Germany -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org

"smplayer" Thats *exactly* the goal the 'new_api' branch is trying to achieve. I offered to work on a new API before and would still love to see it happen. But this needs active collaboration, feedback, and stamina - it won't happen overnight.
