CoffeeScript Project Structure

One of the great benefits of picking up on Coffee on the 16th of this month, two days ago, has been that the onerous task of establishing a development enviornment was simplified by simply copying the CoffeeScript project structure.

Starting on the 16th, and starting with getting Vows to work for testing and Expresso to work for coverage of JavaScript, I created beautiful literate programming articles using docco which gave me an incredible sense of accomplishment. I created an Node.js executable, created an npm installation,

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

"Pick the right ones, and programming will flow naturally from design; 
modules will have small and simple interfaces; and new functionality will
more likely fit in without extensive reorganization. 

Pick the wrong ones, and programming will be a series of nasty surprises: 
interfaces will become baroque and clumsy as they are forced to accommodate 
unanticipated interactions, and even the simplest of changes will be hard to make."
