Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

So I had this situation where I needed to delete an object from the database, if it existed. This is what I wrote:

Ruby Option 1

obj = get_object(1)
obj.destroy if obj

And as I wrote this, it seemed a bit awkward to me. We always said Ruby had a really elegant syntax, but I guess I've come to the place where I find it a little grating. The thing about this example is the asymmetry of it. Conceptually I feel like the if check goes with the assignment, but it's separated from it in a strange way.

Ruby Option 2

function Foo(who) {
	this.me = who;
}

Foo.prototype.identify = function() {
	return "I am " + this.me;
};

function Bar(who) {
	Foo.call(this,"Bar:" + who);
