module.exports = and ES6 Module Interop in Node.js

The question: how can we use ES6 modules in Node.js, where modules-as-functions is very common? That is, given a future in which V8 supports ES6 modules:

• How can authors of function-modules convert to ES6 export syntax, without breaking consumers that do require("function-module")()?
• How can consumers of function-modules use ES6 import syntax, while not demanding that the module author rewrites his code to ES6 export?

@wycats showed me a solution. It involves hooking into the loader API to do some rewriting, and using a distinguished name for the single export.

This is me eating crow for lots of false statements I've made all over Twitter today. Here it goes.

Compass and CSS Sprites, Explained

Last week I attempted to use the CSS sprites feature of Compass for the second or third time. It's been a struggle each time, but the power and potential is there, so I keep coming back. This time was a bit different, though, because I finally decided to stop relying on the docs and dive into the code.

Before I go into the nitty-gritty, let's take a step back and talk about why I

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
