You can view documentation of all features at the This guide will focus on the features of lsp-mode that are most relevant to Clojure development.

Lsp-mode ships with automatic installation scripts for some of the language servers and clojure-lsp Server for Clojure, and has a lot of useful features that I will try to show in this guide. Understands the specifics of your target language.įor Clojure, we will use clojure-lsp which as of 2022/10, is the only LSP Order for it to work, you have to install a separate language server that Lsp-mode is a client-server application with Emacs acting as the client.

Spacemacs or Doom Emacs often ship with lsp-mode settings of their own should you be using such a framework,Īnd find that lsp-mode doesn't behave as intended, please make sure to follow this tutorial from a clean starting point. Please note that Emacs configuration frameworks such as Or to try out in a separate one-off session. Here is a bare-bones lsp-mode configuration template to get you started with your own lsp-mode config, Therefore, if you want to have a more IDE-ish experience with Emacs, you should read this guide. Once it is running (and you are plugged into the REPL), CIDER will provide many of the same features that clojure-lsp does, so you need to tell Emacs how to resolve conflicts, which features use from lsp-mode and which ones from CIDER. You can complement it with clojure-lsp to make programming in Clojure even better. While I really like CIDER and believe it is one of the best tools for Clojure development, Viewing the call hierarchy of a method/function, formatting code automatically, checking syntax in real-time, and using code actions that could, for example, add a missing import.Įver since I found clojure-lsp, which implements most of those features, I have been using it alongside CIDER without issues. Missed a lot of features popularized by Java IDEs, like cleaning unused imports, In your project, you would need to reload the modified namespace/code to see the changes in the REPL. The Emacs package most famous for enabling REPL-driven development with Clojure.Ĭoming from the Java world, when I started programming for Clojure in Emacs, it was odd to me thatįor almost everything you needed to do with Clojure, you needed a REPL running in your project, and if you changed anything Reference-searching, definition-finding, code lenses, code actions and many more. lsp-mode, which has many IDE features like completion, renaming,.A guide on disabling/enabling lsp-mode featuresĪuthor: this guide, I will show you how to configure Emacs to develop Clojure
