It was quite confusing to set up clojure for emacs. Setting up clojure-mode itself was quite easy. Assuming you have the latest emacs with package manager, you can look for clojure-mode. Make sure the package manager is set up by putting this in your .emacs or .emacs.d/init.el file.

(require 'package)
(add-to-list 'package-archives
             '("marmalade" . "") t)

Then do

  • M-x package-list-packages
  • Choose clojure-mode by typing i when you’re on that line
  • Type x to execute the install

You should now have clojure mode. You can test this out by opening a .clj file and see that it says it’s in clojure-mode.

Now I want to connect this to a REPL. If you google search for this, you’ll see mentions of swank and SLIME. If you go to the github page, you’ll see it mention that the project has been deprecated. It is now replaced by nREPL.

Install nREPL by going through the package manager and choose nrepl (yes, you could’ve done this at the same time you installed clojure-mode).
