While grading homework assignments turned in as IPython notebooks, I wanted to insert my remarks as highlighted text in a Markdown cell. You can use the following CSS style and markup to do it. In fact,
In a code cell at the beginning of your notebook, enter:
%%html
<style type="text/css">
span.ecb { background: yellow; }
</style>
Then in any other markdown cell you can put:

Learn Lua quickly with this short yet comprehensive and friendly script. It's written as both an introduction and a quick reference. It's also a valid Lua script so you can verify that the code does what it says, and learn more by modifying and running this script in your Lua interpreter.

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

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.
