coffee-annotate supports to annotate coffee-script methods (and functions).

How to Install

npm i -S coffee-annotate

How to Use

Inheritance Usage

coffee-annotate stores annotation informations into the method property named annotations.

annotate = require 'coffee-annotate'
 
class A
 
  @foo: annotate 'foo'
 
class B extends A
 
  @foo(key: 'value') \
  doStuff: ->
    # do something 
 
b = new B
 
console.log b.doStuff.annotations.foo # print {key: 'value'} 

of course, you can decorate the method.

annotate = require 'coffee-annotate'
 
class A
 
  @log: annotate 'log', (target, annotations) -> (args...) ->
    console.log "enter #{target.name} "
    result = target.body.apply @, args
    console.log "exit #{target.name}"
    result
 
class B extends A
 
  @log() \
  doStuff: ->
    # do something 
 
b = new B
 
b.doStuff() # print 'enter doStuff' and 'exit doStuff' 

Non-Inheritance Usage

i know you don't like to use inheritance to apply annotations to methods. coffee-annotate doesn't need to use annotations inherited from parent class.

x = annotate.class.noAttr 'x'
y = annotate 'y'
z = annotate 'z'
 
x class A
 
 y(key: 'y') \
 z(key: 'z') \
 doStuff: ->
   # do something 
 
a = new A
 
console.log a.annotations.x? # print true 
console.log a.doStuff.annotations.y # print {key: 'y'} 
console.log a.doStuff.annotations.z # print {key: 'z'} 

Just Function

if you don't annotate methods but functions, sure you can.

annotate = require 'coffee-annotate'
 
$foo = annotate 'foo'
 
doStuff = $foo(key: 'value') ->
  # do something 
 
console.log doStuff.annotations.foo # print {key: 'value'} 

Without Attributes

if your annotation don't need to accept any attributes, you can write annotations with annotate.noAttr function.

annotate = require 'coffee-annotate'
 
class A
 
  @foo: annotate.noAttr 'foo'
 
class B extends A
 
  @foo \
  doStuff: ->
    # do something 
 
b = new B
 
console.log b.doStuff.annotations.foo # print {key: 'value'} 

API

annotate(name, decorator)

• name: String

  name is the key of annotations property.

• decorator: ({name: String, body: Function}, attributes: Any): Function

  decorator for the actual method or function. it must return a function even if you don't need to decorate the function. this parameter is optional.

  name property is the annotated function's name. and body property is the function which is annotated. attributes parameter is annotation's arguments, so it could be any type.

annotate.noAttr(name, decorator)

same as annotate but the annotation can't accept any attributes.

annotate.class(name, decorator)

• name: String

  name is key of annotations property for constructor function aka class.

• decorator: (clazz: Function), attributes: Any): Function

  decorator for the actual class. it must return a constructor function even if you don't need to decorate the constructor function. this parameter is optional.

  clazz property is the annotationed constructor function. attributes parameter is annotation's arguments, so it could be any type.

annotate.class.noAttr(name, decorator)

same as annotate.class but the annotation can't accept any attributes.
