@dalias while i don't use an ide, i do use neovim with a lsp for c

mostly because i have a tendency to typo things and the "edit, save, compile, look at errors" loop is overwhelming to me, seeing only errors on the line (or around it) i'm working on helps a lot. also sometimes for auto-complete when function names are like namespaced plus long names

but to me they're just aids, languages or frameworks that depend on such things to exist feels like they're going backwards: "oh those helpers exist therefore we can make the underlying thing complex as no one will interact with it" is the opposite way technologies should go imo
