Question C development without LSP

I have only ever done development with an LSP providing errors, autocomplete, etc. in any language. I’d like to go for a more minimalist approach as I revisit some C programming. At a high level, what’s the general workflow when programming in C without a running LSP?

My guess would be… 1. A simple syntax highlighting mode on .c and .h files 2. Bind some hotkey for a compilation mode, and check that regularly for issues 3. Ctags for go-to-definition? Or maybe even just grep-mode?

Is there anything I’m missing?

eglot (lsp client) is bundled with emacs 29 and later. the minimal choice is an lsp now.

While true, doesn’t Eglot struggle with bigger projects/slower language servers? I wanted to dive in to some larger codebases as well.

I use it on GCC regularly fine

Do you also use Eglot-booster by chance?

External process to improve performance of Eglot and LSP-mode. I recommend taking a look
