Provides Emacs font-lock, indentation, and navigation for the Clojure language.
It's easiest to install and keep Clojure Mode updated using package.el.
;; add to ~/.emacs.d/init.el if you aren't already using Marmalade.
(require 'package)
(add-to-list 'package-archives
'("marmalade" . "http://marmalade-repo.org/packages/"))
(package-initialize)
M-x eval-buffer
M-x package-refresh-contents
M-x package-install clojure-mode
If you use a version of Emacs prior to 24 that doesn't include package.el, you can get it from http://bit.ly/pkg-el23. If you have an older package.el installed from tromey.com, you should upgrade in order to support installation from multiple sources.
Of course, it's possible to just place it on your load-path and require it as well if you don't mind missing out on byte-compilation and autoloads.
Using clojure-mode with paredit is highly recommended. It is also available using package.el from the above archive.
Use paredit as you normally would with any other mode; for instance:
;; (require 'paredit) if you didn't install via package.el
(defun turn-on-paredit () (paredit-mode 1))
(add-hook 'clojure-mode-hook 'turn-on-paredit)
Use M-x run-lisp to open a simple REPL subprocess using Leiningen. Once that has opened, you can use C-c C-r to evaluate the region or C-c C-l to load the whole file.
If you don't use Leiningen, you can set inferior-lisp-program to
a different REPL command.
You can also use Leiningen to start an enhanced REPL via SLIME:
$ lein plugin install swank-clojure 1.3.3
M-x clojure-jack-in # from inside a project
