> mixin consumer, modules...
Mix modules' methods to the model.
class Person
person = new Person()
Talkable =
speak: ->
console.log "Yeah!"
Moveable =
walk: (speed) ->
console.log "Walk by #{speed}"
run: (speed) ->
console.log "Run by #{speed}"
Caphe.mixin(person, Talkable, Moveable)
person.speak() # "Yeah!"
person.walk(8) # "Walk by 8"
person.run(5) # "Run by 5"> include module[, names...]
Like mixin but do it Ruby style. Optionally, specify name of methods that will be included
Talkable =
speak: ->
console.log "Yeah!"
class Person extends Caphe
@include Talkable
@include Moveable, 'run'
person = new Person()
person.speak() # "Yeah!"
person.run(6) # "Run by 6"
person.walk(4) # undefined> attrAccessor names...
Create getter & setter methods in Ruby style and hide the properties from public access.
class Person extends Caphe
@attrAccessor "name", "age"
constructor: (@job) ->
person = new Person("Bar")
person.setName("Foo")
person.getName() # Foo
person.name # undefined
person.getAge() # undefined
person.setAge(5)
person.getAge() # 5
person.age # undefined
person.job # Bar> CONST name: value, ...
Create constant getters in prototype level.
class Person extends Caphe
@CONST EYE: 2, SPECIES: 'homo sapiens'
Person::EYE() # 2
Person::SPECIES() # homo sapiens> forward consumer, providers...
Mixin with late bound. The forwarded methods have each own module as their context.
module.foo = -> console.log "a"
module.bar = -> console.log @name
Caphe.forward(person, module)
person.foo() # a
person.bar() # undefined
module.bar = -> console.log "b"
person.bar() # b> delegate consumer, providers...
Like #forward, but the forwarded methods have the consumer as their context.
person.name = "John"
module.foo = -> console.log "a"
module.bar = -> console.log @name
Caphe.delegate(person, module)
person.foo() # a
person.bar() # John
module.foo = -> console.log "b"
person.foo() # b
