![]() ![]() ![]() The essential modes being used are the following: Otherwise you can add a snippet like below to your init.el: (unless (package-installed-p 'use-package) It will be auto-installed in the standalone version of this config. Note that I use use-package for Emacs package management. Note that the config will likely work with older Emacs versions but Emacs 27 got substantial improvements around JSON parsing which speeds up LSP clients quite a bit. On Ubuntu adding another apt repository is necessary. On Windows I use the “nearby GNU mirror” link at gnu.org/software/emacs. This should work with older versions of the relevant emacs packages as well. The rksm/emacs-rust-config github repo contains a standalone.el file that you can use to start Emacs with: If you have already Rust and Emacs installed (see prerequisites) you can get quickly up and running without modifying any of your existing configuration. : rust-analyzer installation / compatibility note.: Note about broken lsp-lens-mode / inlay hints.: Inlay hints fixed & more inlay hints available.: Clarified that rustic derives from rust-mode. ![]() : Note about potential LSP :: rust-analyzer failed to discover workspace error (thanks Fred Xia!).: Use lsp-format-buffer instead of rustic-format-on-save.I’ve tested the configuration with Emacs 28.1, rust stable 1.62.0 and on macOS 12.4, Ubuntu 18.04 and Windows 10.įor a setup that uses the emacs-racer backend 1 please see David Crook’s guide. This post is accompanied by a github repository that you can use as a reference or directly checkout and run Emacs with ( see below). This setup will be based on rust-analyzer, a LSP server that is under very active development and powers the Rust support in VS Code as well. Building & running other cargo commands.Automatically import definitions if necessary (such as for Traits).Highlighting errors and warnings inline.Navigating the source code (go to to implementation, list references, outline module structure).This post will walk you through setting up Emacs to allow for: Rust support in Emacs improved a lot during the past two years. ![]()
