How to run csound command to check code only?

Hi community!

I’m learning how to write LSP servers from this tutorial and I will need to evaluate csound code with its csound command. My issue now is that I couldn’t find a flag that could run csound dry without doing all the processing although there’s -n flag that doesn’t write to disk. I’ve checked out Pasquale’s work in rust but I didn’t how he run csound command for his language server.

How can evaluate my code without running CSound audio engine?

isn’t this --syntax-check-only?
