From: the_wurfkreuz <the_wurfkreuz <at> proton.me> To: "bug-gnu-emacs <at> gnu.org" <bug-gnu-emacs <at> gnu.org> Subject: 31.0.50; Stutters using eglot with lua-language-server Date: Tue, 14 Jan 2025 18:37:05 +0000
[Message part 1 (text/plain, inline)]
I get stutters when i use eglot with the lua-language-server. It usually happens when i use the 'newline' command. Steps to reproduce: 1. emasc -Q 2. Open any lua file and enable lua-mode or lua-ts-mode (i tested on neovim config files). 3. Enable eglot by executing 'eglot'. 4. Execute 'newline' by pressing <RET>. This action should create an easily noticeable stutter.

I think it would help if you run this several times after "M-x profiler-start" and then present the profile by invoking "M-x profiler-report". The profile could give us hints regarding the expensive processing in these cases. Thanks.

I couldn't tell from the profile in the email, only after seeing the mem profiles. Now I've read the thread and understand this happens when you type a newline. Well, this is expected if you have the :documentOnTypeFormattingProvider capability enabled and you have a slow-to-respond language server. Eglot will wait for the server to process the inserted character and send back an edit that reformats the buffers. This wait is synchronous (there is no way to make it asynchronous). To remove this behaviour, just put :documentOnTypeFormattingProvider in eglot-ignored-server-capabilities (via custom or Elisp, see its docstring). I've been pondering changing the variable's default value to have that capability ignored by default. I just don't do it because it sort of clashes with the reasonably consistent policy that Eglot enables as much of LSP as it can by default. But I feel this LSP feature is a bit too laggy to be on by default. Although it generally works OK if you have a fast server. Opinions on this are welcome. The fact that there's a sync wait on an IPC object also probably explains why this doesn't show up in the CPU profile. João
