Why Coughy? Well, CoffeeScript gives JavaScript a much more palatable syntax. Of course, each of your projects include the lovely [[http://underscorejs.org/][Underscore]] library, however, pre-pending =_.= makes your code look crummy.

Coughy is quite wrong in that it places the Underscore library into the global name space. /WHAT!?/ Yes. Just look at this beautiful code:

+BEGIN_SRC coffee

Sum the squares that are less than 25... right, it is 30.

reduce( map( range(5), (x) -> x * x ), (total, cur) -> total + cur )

+END_SRC

Why do this? This certainly isn't for everyone, or every project, but for working on [[http://projecteuler.net/][Project Euler]], or teaching programming concepts, this seems like an acceptable solution.

** Installation

As usual, you can take advantage of this project by adding this to your normal Node-related project:

+BEGIN_SRC sh

npm install coughy

+END_SRC

Now, you can create scripts that use those functions directly:

+BEGIN_SRC js

require('coughy');

+END_SRC

Note: You do not need to assign the results of the coughy module *because , it is already placed in the global namespace.

** REPL Sweetness

By using the [[http://danielgtaylor.github.io/nesh/][Nesh project]], we can make pre-load /coughy/ in order to make a better REPL:

+BEGIN_SRC sh

npm install -g nesh

+END_SRC

Then, create a Shell function like this:

+BEGIN_SRC sh

nesh --lang coffee --eval 'node_modules/coughy/coughy.js'

+END_SRC

Where =coughy.js= needs to be the filename to the magic script that provides this pleasing abomination.

** Futures

Think of this... An even more functional approach to development is with something like the immutable data structures available from [[http://swannodette.github.io/mori/][Mori]] ... However, since Mori's functions overlap with Underscore (but seem to be more general), I may just swap it.
