mang0 is still raw…

Create a directory “~/bin”

$ cd ~/bin

Download “lein”

$ wget https://github.com/technomancy/leiningen/raw/1.6.1/bin/lein

Install packages

$ aptitude -Ry install emacs23-nox openjdk-6-jdk

Create a project directory

$ lein new myproject

Edit project.clj

$ cd myproject
$ emacs project.clj

Add “swank-clojure” and “clojure-contrib” lines to it

File should look like this

(defproject myproject "1.0.0-SNAPSHOT"
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.2.1"]
[org.clojure/clojure-contrib "1.2.0"]]
:dev-dependencies [[swank-clojure "1.2.1"]])

Save file and exit out of emacs

Download “lein” dependencies

$ lein deps

Install “emacs” packages

Open following link in browser
http://tromey.com/elpa/install.html

Open “emacs” and Switch to *scratch* buffer

$ emacs -nw and then C-x C-b *scratch*

Follow instructions given on “install.html” link, alternatively copy following
code to *scratch* buffer

(let ((buffer (url-retrieve-synchronously
"http://tromey.com/elpa/package-install.el")))
(save-excursion
(set-buffer buffer)
(goto-char (point-min))
(re-search-forward "^$" nil 'move)
(eval-region (point) (point-max))
(kill-buffer (current-buffer))))

Evaluate above code using “M-x eval-buffer” command

Install “emacs modes”

Run “M-x package-list-packages”

Install “swank-clojure” package
Use “C-s” to Search package name
Use “i” to select package and then press “x” to install.
This should also install “clojure-mode” “slime” “slime-repl” packages.

Run “swank server”

Switch to another terminal
$ cd ~/myproject
$ lein swank

This will start “swank” server on 127.0.0.1:4005 by default

Connect to “swank” using “slime”

Go back to running emacs instance and type

“M-x slime-connect”

It will prompt for “host” and “port”, press to accept default values

Your Hacking Starts Now!!!

You may get a version mismatch warning after running “slime-connect”. To remove
this warning

$ cd ~/.emacs.d/elpa/slime-20100404/
and remove .elc file
$ rm slime.elc
