Now if you insist in vim and Emacs, there is printf. That's just plain wrong. GDB for example has had pretty printers for STL data structures for many years. Those operate on the underlying structure of the data types and you can write printers for your own data types pretty easily (gdb uses python for these). Apart from that, there is structured hierarchical logging, which seems to be on the way of becoming an industry standard and is considered best practice in some ecosystems (golang comes to mind)
