Vows At

=======

> Even less redundant [vows](http://vowsjs.org)

Introduction

------------

This library should be used with [LiveScript](http://livescript.net) or [CoffeeScript](http://coffeescript.org).

It executes the *vows* in an scope where:

* `@topic` is the topic

* `@error` is the error if the topic was defined asynchronously

* `@` contains all the `assert` module functions redefined:

  * By default the first param is `@topic`.

  * If it is called with the same number of params that its original function, it expects that the first parameter is callable. It will call the function with `@topic` as its argument, and it will use the result as the first parameter for the assert.

The benefit of this is best seen with an example.

Example

--------

Here is a simple example written in `LiveScript`:

```livescript

require! {

  vows

  at: \vows-at

}

vows.describe 'Division by Zero'

  ..add-batch {

    'when dividing a number by zero':

      topic: -> 42 / 0

      'we get Infinity': at -> @equal Infinity

    

    'but when dividing zero by zero':

      topic: -> 0 / 0

      'we get a value which':

        'is not a number': at -> @is-NaN!

        'is not equal to itself': at -> @not-equal @topic

  }

  ..add-batch {

    'when the topic is an object':

      topic: -> { number: 0 / 0 }

      'you can check its properties easily': at -> @is-NaN (.number)

  }

  ..export module

```
