What happened to Lime? [1] It looked promising (especially since it was from the author of SublimeClang [2] which worked like a charm, but now it's dead too and doesn't work with SublimeText 3), but there hasn't been any activity for half a year.

Is there any plugin/editor combination that still does C completion like SublimeClang used to do?
