shutdown was ignored before this commit. @Atemu could you confirm whether this PR fixes #499 ?

[Atemu]

Nixd now shuts down "cleanly" from eglot's perspective, thank you!

The exit signal is 9; not sure whether that's expected or not.

[inclyc]

The exit signal is 9;

What did you mean by "exit signal"?

[Atemu]

Sorry, I meant exit code. it's just what eglot reports to me.

[inclyc]

Sorry, I meant exit code. it's just what eglot reports to me.

No, the exit code should be 0 though. How about paste some logs here then?

[Atemu]

Actually, I have misread: It says "status 9", not "exit code":

[eglot] Asking EGLOT (nixfiles/(nix-mode)) politely to terminate
[jsonrpc] Server exited with status 9

It's the same status code when I exit haskell-language-server, so it's probably correct.

Getting logs is surprisingly hard because eglot justifyably clears all log buffers upon successful shutdown.
