coffee-mixin

Powerful mixins and monkeypatches for coffeescript.

mix = require("coffee-mixin")

class A
constructor: -> console.log "hello"
world: -> console.log "world"

class B

constructor: -> super()
world: -> super()

C = mix A, B

new C().world()
#
# hello
# world

The mix function takes any number of classes as parameters.

Wrap Super (Monkeypatch)

Automatically call super before or after each function is executed.

Transparently monkeypatch, even on constructors!

mix = require("coffee-mixin")

class A

# CoffeeScript does not return by default in constructors.
#
constructor: -> return "hel"
world: -> "wor"

class B
constructor: (str) -> console.log "#{str}lo"
world: (str) -> console.log "#{str}ld"

C = mix A, B, prepend: true

new C().world()
#
# hello
# world

$3

mix = require("coffee-mixin")

class A
constructor: (str) -> console.log "#{str}lo"
world: (str) -> console.log "#{str}ld"

class B

# CoffeeScript does not return by default in constructors.
#
constructor: -> return "hel"
world: -> "wor"

C = mix A, B, append: true

new C().world()
#
# hello
# world
