Mixmaster

v0.1.0

A class for faking multiple inheritance in Coffeescript using mixins.
Mixmaster also provides a function (init) for running the constructors of all your
mixin classes.

To make a Mixmastered class:

class Translator extends Mixmaster
mixins = [
German
Japanese
English
]
@include mixins

constructor: ->
Mixmaster.init mixins

linguist = new Translator

That's it!

The mixin classes and the results are below.

You can inherit from basic classes.

class German
constructor: (worldNews) ->
worldNews.germany = 'good news'

german: -> console.log 'Guten tag.'
greeting: -> console.log 'Hallo.'

You can see Mixmaster.init is called above with an args... splat.
This is so your parent classes will receive any extra parameters they might need:

class Japanese
constructor: (worldNews, weather) ->
worldNews.japan = {
news: 'bad news'
weather: weather
}

japanese: -> console.log 'こんにちは'

You can override methods found in other inherited clases
by adding the class later in the mixin array.
As long as you are running Mixmaster.init in your constructors you can also inherit from other Mixmaster classes:

class LinguistJargon
writePaper: -> console.log 'My paper is on ...jargon jargon...'

class English extends Mixmaster
mixins = [LinguistJargon]
@include mixins

greeting: -> console.log "Hi!"

Instantiate as normal...

worldNews = {}
weather = 'great'
linguist = new Translator worldNews, weather

...and away you go!

linguist.german() # Guten Tag
linguist.japanese() # こんにちは
linguist.writePaper() # My paper is on ...jargon jargon...
linguist.greeting() # Hi!
console.log worldNews # { germany: 'good news',
# japan: { news: 'bad news', weather: 'great' } }
