syntax completion has existed since 1957, and templating (or macros that implement templates) has been in editors long enough I don’t think anyone remembers when they got added (but here’s TECO (1962) anyway. the implementations of these things that run inside your editor are lightweight, predictable, and don’t increase carbon emissions by 30%, and it’s really weird that you’re in this thread cosplaying as a programmer but somehow don’t know basic shit about how code’s written, actually??? why is that, I wonder.

yes, computing systems use energy

come the fuck off it. so much of computer science involves studying algorithmic efficiency, something you just tried to talk past. it’s how we know that the regular expressions and push-down automata we implement in editors to do fast efficient syntax completion are a better fucking idea than using some shit that does the same thing less reliably and consumes so much fucking energy doing it that it increases greenhouse emissions by 30 fucking percent
