these days my only c use is via obj-c in xcode, so i may well be unaware of the state of the art for straight c or straight c++ / other tools. xcode's refactorings and jump-to-defn (presumably powered by clang?) are still very flaky for me. for go, i use: goimports -- which is gofmt (which is awesome) + auto-adding/removing imports (just a heuristic so not always right, but usually right and quite handy) godef -- for jumping to definitions gorename -- for rename refactorings. i have not once gotten this to break code. oracle -- for showing other things about code, like 'which types implement this interface?'. as far as i can tell, it hasn't lied to me yet. i use emacs as my editor, which integrates easily w/ all of the above tools. i'm not sure what libraries power the tools above, but i think it's true that packages like go/types do the heavy lifting and make them relatively easy to write.
