Boost eglot using lsp-booster

eglot-booster: Boost eglot using lsp-booster

The emacs-lsp-booster project provides a rust-based wrapper program which substantially speeds up emacs' interactions with lsp servers. This small package enables eglot to use it.

Install/Usage

Install directly from this repo via M-x package-vc-install (pasting in this URL), or using, e.g. straight. Then, in your init, simply

(use-package eglot-booster
	:after eglot
	:config	(eglot-booster-mode))

Then just use eglot as normal. You should notice no differences other than speedier performance and less I/O blocking.

To verify that the wrapper is functioning, M-x eglot-events-buffer and look at the beginning for emacs_lsp_booster::app notices.

Important

At present only local lsp server programs which communicate by standard input/output can be wrapped, not lsp servers communicating over network ports (local or remote).

Testing

Maybe you don't even need this. You can M-x eglot-booster to disable the booster at any time. Then M-x eglot-shutdown-all, restart eglot (M-x eglot is usually enough) in a large/heavy-weight file, and compare performance before and after.
