Installation
Available on both Marmalade and MELPA repos.Marmalade is recommended as it has the latest stable version, but MELPA has a development snapshot for users who don't mind breakage but don't want to run from a git checkout.
If you're not already using Marmalade, add this to your
~/.emacs.d/init.el and load it with M-x eval-buffer.(require 'package)
(add-to-list 'package-archives
'("marmalade" . "http://marmalade-repo.org/packages/"))
(package-initialize)
(require 'package)
(add-to-list 'package-archives
'("melpa" . "http://melpa.milkbox.net/packages/") t)
(package-initialize)
M-x package-refresh-contents
M-x package-install [RET] clojure-mode [RET]
or if you'd rather keep it in your dotfiles:
(unless (package-installed-p 'clojure-mode)
(package-refresh-contents)
(package-install 'clojure-mode))
clojure-mode.el on your load-path
and requireing it.Clojure Test Mode
This source repository also includesclojure-test-mode.el, which
provides support for running Clojure tests (using the clojure.test
framework) via nrepl.el and seeing feedback in the test buffer about
which tests failed or errored. The installation instructions above
should work for clojure-test-mode as well.Once you have a repl session active, you can run the tests in the current buffer with C-c C-,. Failing tests and errors will be highlighted using overlays. To clear the overlays, use C-c k.
You can jump between implementation and test files with C-c C-t if your project is laid out in a way that clojure-test-mode expects. Your project root should have a
src/ directory containing files that
correspond to their namespace. It should also have a test/ directory
containing files that correspond to their namespace, and the test
namespaces should mirror the implementation namespaces with the
addition of "-test" as the suffix to the last segment of the namespace.So
my.project.frob would be found in src/my/project/frob.clj and
its tests would be in test/my/project/frob_test.clj in the
my.project.frob-test namespace.Paredit
Using clojure-mode with Paredit is highly recommended. It helps ensure the structure of your forms is not compromised and offers a number of operations that work on code structure at a higher level than just characters and words.It is also available using package.el from the above archives.
Use Paredit as you normally would any other minor mode; for instance:
;; (require 'paredit) if you didn't install it via package.el
(add-hook 'clojure-mode-hook 'paredit-mode)
REPL Interaction
A number of options exist for connecting to a running Clojure process and evaluating code interactively.Basic REPL
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.nrepl.el
You can also use Leiningen to start an enhanced REPL via nrepl.el.Ritz
Another option is Ritz, which is a bit more complicated but offers advanced debugging functionality using SLIME.Swank Clojure
SLIME is available via swank-clojure inclojure-mode 1.x.
SLIME support was removed in version 2.x in favor of nrepl.elfrom https://github.com/magnars/clojure-mode
