Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

Step 1: Getting Clojure (1.3)

Linux

Setup

# If inside vmware install vmware tools (these are just as good as the commercial ones)
sudo apt-get install open-vm-tools open-vm-tools-desktop

# Install git
sudo apt-get install git

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

How to use the script below

Requirements:

aws-sdk: ~> 1.20.0

Two files are required: ~/.aws/config and a file containing instances ids, one per line, eg:

~/.aws/config

	/*
	* Tested on node 0.6, Ubuntu
	*/
	#!/usr/bin/node

	COLOR_GREEN="\033[01;32m"
	COLOR_RED="\033[01;31m"
	COLOR_YELLOW="\033[01;33m"
	COLOR_BLUE="\033[01;34m"
	COLOR_NORMAL="\033[00m"

	import re, sys, json

	TOKENS = {
	'NUMBER': '[0-9]+',
	'IDENTIFIER': '[a-zA-Z][a-zA-Z0-9]*',
	'ADD': '\+',
	'SUB': '-',
	'POW': '\^',
	'MUL': '\*',
	'DIV': '/',

	gifify() {
	if [[ -n "$1" ]]; then
	if [[ $2 == '--good' ]]; then
	ffmpeg -i $1 -r 10 -vcodec png out-static-%05d.png
	time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png GIF:- \| gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $1.gif
	rm out-static*.png
	else
	ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - \| gifsicle --optimize=3 --delay=3 > $1.gif
	fi
	else

	var empty_list = function(selector) {
	return selector(undefined, undefined, true);
	};

	var prepend = function(el, list) {
	return function(selector) {
	return selector(el, list, false);
	};
	};
	var head = function(list) {

	class Class1():
	pass

	class Class2():
	pass

	class Class3(object):
	pass

	a = Class1()

	#!/bin/bash

	set -e # Exit script immediately on first error.
	#set -x # Print commands and their arguments as they are executed.

	# generate war file with ant or gradle or whatever you want
	ant war

	# upload the generated war file to the web server
	scp -P 5122 target/war/MyApp-SNAPSHOT.war [email protected]:~/MyApp.war
