Node.js generator examples

This provides some basic examples of how Node.js generators can be used, while also describing their functionality through tests.

The main files are:

• test/ - in this directory there are some test-driven examples of how generators can be used, and what calling generator.next() does
• generators.js - this shows some simple generator examples.
• dns_lookup/ - this folder contains three ways of doing the same task, looking up the ip address of a domain and writing it to a file. One way uses vanilla callbacks, the other, a generator with thunks built from scratch, and the other a generator with thunks built using thunkify, and the generator run using co.

Setup

Make sure you have at least node node v0.11.11 (unstable)

node -v

The printed version should be 0.11.11 or above.

To download the latest version of node, go to (http://blog.nodejs.org/release/) and download and install the latest release for your os. Note that v0.11.11 and up are unstable releases of Node.

Install dependencies

npm install

Run the tests

make test

Run the generators

To run any of these generators, you must start node with the --harmony flag:

node --harmony

Example of how to run a particular generator:

```javascript
var generators = require('./generators');
basicGenerator = generators.basic();
basicGenerator.next();
basicGenerator.next();
```
