Vagrant / Clojure / Emacs - emacs

Question

I want to put together a standard environment for exploring Clojure with Emacs. Has anyone got a recipe that would suit this? I'm thinking of a Vagrant system running a flavour of Ubuntu, with NREPL and some useful EMACS support plugins.

Answer 1

vagrant box add preciseMinimal http://goo.gl/wxdwM
Change to Clojure vagrant base folder
vagrant init preciseMinimal
vagrant up
vagrant ssh
or ssh to 127.0.0.1 port 2222 (or other port mentioned in "vagrant up" output)
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:cassou/emacs
sudo apt-get update
sudo apt-get install emacs24 emacs24-el emacs24-common-non-dfsg
sudo apt-get install clojure
cd ~/
mkdir bin
sed '$ a\
export PATH=~/bin:$PATH' ~/.bashrc
exit and reconnect to ssh
cd ~/bin
wget https://raw.github.com/technomancy/leiningen/preview/bin/lein
chmod +x lein
./lein
cd ~
cat >.emacs

A Github hosted, shell provisioned vagrant setup is located here:
https://github.com/pattinsont/Ukelele
All that should be required is a checkout and vagrant up.
Once the VM is up, ssh onto box.
Run emacs to complete install.
