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)

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

# AwesomeRouter: A class that I've been using throughout a few Backbone.js apps I've built.
#
# It adds 2 features: an event that gets fired when one calls `navigate` (aptly named
# "navigate"), so you can bind things to when a URL gets triggered. And a "before filter"
# method `before`, which you can use to run things before every a route gets triggered.
#
# This could easily be extended to have after filters too, or to only trigger a route
# upon @before returning something that's not false.

Until last night I lived in fear of tildes, carats, resets and reverts in Git. I cargo culted, I destroyed, I laid waste the tidy indicies, branches and trees Git so diligently tried to maintain. Then Zach Holman gave a talk at Paperless Post. It was about Git secrets. He didn't directly cover these topics but he gave an example that made me realize it was time to learn.

A better undo

Generally, when I push out bad code, I panic, hit git reset --hard HEAD^, push and clean up the pieces later. I don't even really know what most of that means. Notational Velocity seems to be fond of it ... in that I just keep copying it from Notational Velocity and pasting it. Turns out, this is dumb. I've irreversibly lost the faulty changes I made. I'll probably even make the same mistakes again. It's like torching your house to get rid of some mice.

Enter Holman. He suggests a better default undo. git reset --soft HEAD^. Says it stag

(function(win, doc){

	function docHijack(p){var old = doc[p];doc[p] = function(v){return addListen(old(v))}}
	function addEvent(on, fn, self){
		return (self = this).attachEvent('on' + on, function(e){
			var e = e || win.event;
			e.preventDefault  = e.preventDefault  || function(){e.returnValue = false}
			e.stopPropagation = e.stopPropagation || function(){e.cancelBubble = true}

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

If you prefer VirtualBox or aren't running OS X, here are some instructions and a script to help you get started with SmartOS under VirtualBox. If you use VirtualBox, skip the first section and read the section on how to get the Node.js SmartMachine up and running.

Running SmartOS under vmware Fusion

1. Start by downloading the latest live image
2. When you run the new VM wizard, select "Continue without disk" on the first screen of the wizard.
3. Select Sun Solaris / Solaris 10 64-bit on the next screen.
4. You're going to get dumped to a config screen when the live image starts up, choose DHCP for the networking and defaults for everything else.
5. Pretty much the first thing you're going to want to do is figure out how to SSH into the box once it boots and creates its storage pools, because trying to do stuff in the virtual console is miserable. There's no cut and paste
