Package definitions

[ghost]

Hi, Jeremy! I wrote some code on my work. All code was for the browsers and I need to protect classes by packing them into packages. My preparsers was dirty with regexps, but now I decide to make it right and I want to suggest using packages as standart coffeescript tool. By the way thx a lot for coffee, it awesome!

Usage example, this code creates class cafe.dom.Window:

  package "cafe.dom"

    class Window

      @getViewPortSize: () ->
        myWidth = 0
        myHeight = 0

        if typeof window.innerWidth is 'number'
          #Non-IE
          myWidth  = window.innerWidth
          myHeight = window.innerHeight
        else if (doc = document.documentElement) and (doc.clientWidth or doc.clientHeight)
          #IE 6+ in 'standards compliant mode'
          myWidth  = doc.clientWidth
          myHeight = doc.clientHeight
          doc = null
        else if (body = document.body) and (body.clientWidth or body.clientHeight)
          #IE 4 compatible
          myWidth  = body.clientWidth
          myHeight = body.clientHeight

        return {
          width : myWidth
          height: myHeight
        }

See #1141, #684. We don't need a special syntax for this.

Why not, I can't understand. Keyword package is reserved in JS and it means to create packages. Yes, it's not very useful for server side dev, but in the browsers it helps to safe classes from override. Each time write something like this:

  @cafe or= {}
  cafe.dom or= {}

  cafe.dom.Window = class Window

it's not cool and not compact. You couldn't understand what is it at the first look. But if you look at this:

  package "cafe.dom"
    class Window

all clear! Believe me it wouldn't be a special function, it's like shortcut, like class keyword for example.
