npm install shy-co

#version 0.1.2

it's stable

#How to Use 'use strict' let co=reuqire('shy-co')

co(function*(){
	let x
	x=yield [666,Promise.resolve(6)]
	console.log(x)//log:[666,6]
	x=yield Promise.resolve(6)
	console.log(x)//log:6
	x=yield ()=>7
	console.log(x)//log 7
	x=yield 666
	console.log(x)//log: 666 (ps:return self)
	x=yield Promise.reject(6)
	console.log(x)//not run
}).then(
	null,
	err=>console.log(err)//log:6
)

#Advantage

you can yield anything

if you yield x ,it will do yield co(x) ps:Promise>[]>function*>function>value

#ES3 //实例 var co = require('shy-co/es3.js')//兼容ie8,但是用法不一致 co(function gen(yield){//名字含有gen的函数会得到一个taskAdd函数作为参数 yield(function(){ return 0 }) yield(function Promise(val,rj,rj){//名字含有promise的函数会多出两个参数promise构造函数中的resolve,reject console.log(val)//log:0 rl(1) }) yield(function(val){ console.log(val)//log:1 throw 2 },function err(err){//这个函数会被添加到promise中的catch参数中,没有的话错误直接抛出 console.log(val)//log:2 return 2 }) })

#update 0.1.7 ~ 0.1.10 bug修复,某些情况下错误不被抛出

0.1.6 进行一些优化

0.1.5 增加ie8直接使用,不过写法不一样,依赖native-promise-only包

0.1.4 BUG修复

0.1.3 BUG修复,内部错误忘记抛出

0.1.2 let promisify = require('shy-co/promisify')
