Go language 1 hours--never to get started

Ax--go Language Learning Essential Information:
1. Go download and install
2. Official document effective Go
3. Official documents Chinese translation PDF download
4. Chinese-written go ide--liteide 32.1

The first step--hello world

Testdemo Project Main.go Package
main

import (
    "FMT"
)

func main () {
    fmt. Println ("Hello world!")
}

The second step--project structure
Go install and go build contention. The idea plugin and liteide are now using go build. The Eclipse plugin uses go install. Official recommended go install way to compile the project, the official project structure should be

Project name
  |--bi
  |--pkg
  +--src

Step three--package Main, func main () {}, func init () {}

A picture wins thousands of words

Fourth Step--go Language object-oriented

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 () { C29/>p: = person{name: "Dave"}
    C: = citizen{person:person{name: "Steve"}, Country: "America"}

    Speakto (&p )
    Speakto (&c)
}

Fifth Step--go language concurrency

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."
}
