go 学习笔记（4） ---项目结构

go install和go build之争。目前，IDEA插件和LiteIDE都采用了go build。Eclipse插件采用了go install。官方推荐go install方式编译项目，官方项目结构应该是

项目名称
  |--bi
  |--pkg
  +--src

package main、func main() { }、func init() { }

go语言面向对象

// File Name: main.go
package main

import (
    "fmt"
)

type Human interface {
    Talk()
}
type Person struct {
    name  string
    Human // Person is-a Human
}

func (p *Person) Talk() {
    fmt.Println("Hi, my name is", p.name)
}

type Citizen struct {
    country string
    person  Person
    Human   //B is-a A
}

func (c *Citizen) Talk() {
    fmt.Println("Hi, my name is", c.person.name)
}

func SpeakTo(h Human) {
    h.Talk()
}

func main() {
    p := Person{name: "Dave"}
    c := Citizen{person: Person{name: "Steve"}, country: "America"}

    SpeakTo(&p)
    SpeakTo(&c)
}

go语言并发

// File Name: main.go
package main

import (
    "fmt"
)

var ch = make(chan string)

func message() {
    msg := <-ch
    fmt.Println(msg)
}

func main() {
    go message()
    ch <- "Hello,CSP."
}
