Linux & Go & Vscode & 插件

Linux Deepin 安装Go

安装Go环境

sudo apt-get install golang

验证一下：

输入

$ go env

输出

GOARCH="amd64"
GOBIN=""
GOCACHE="/home/sunchong/.cache/go-build"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/sunchong/go"
GORACE=""
GOROOT="/usr/lib/go-1.10"
GOTMPDIR=""
GOTOOLDIR="/usr/lib/go-1.10/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"

安装IDE

    我这里选择了vs code
    应用商店或者官网上安装好vscode

    安装go 插件：搜索一下插件，安装量最高的那一个就是，Go for Visual Studio Code

安装Go组件

    当我们正想愉快的使用IDE进行开发go时，保存后会提示我们安装go相关的组件。。。

    我们点击安装 Install  All
    有几个是可以安装成功的，有几个死活也装不上啊，开启FQ也不行。

下面我们按照这个步骤再来一下

1. $GoPath/src/golang.org/x/tools

     你的GoPath 目录下是否存在以上文件夹？没有新建
   

2. tools 目录下我们git一下

       git clone https://github.com/golang/tools.git
   

3. tools 下会有一个tools文件夹

          拷贝出来替换tools
   

4. 执行命令

go install github.com/ramya-rao-a/go-outline

go install github.com/acroca/go-symbols

go install golang.org/x/tools/cmd/guru

go install golang.org/x/tools/cmd/gorename

go install github.com/josharian/impl

go install github.com/rogpeppe/godef

go install github.com/sqs/goreturns

go install github.com/golang/lint/golint

go install github.com/cweill/gotests/gotests

go install github.com/ramya-rao-a/go-outline

go install github.com/acroca/go-symbols

go install golang.org/x/tools/cmd/guru

go install golang.org/x/tools/cmd/gorename

go install github.com/josharian/impl

go install github.com/rogpeppe/godef

go install github.com/sqs/goreturns

go install github.com/golang/lint/golint

go install github.com/cweill/gotests/gotests

写点啥吧

package main

import (
	"fmt"
	"os"
)

func main() {
	if len(os.Args) > 1 {
		fmt.Println("Hello World", os.Args[1]+os.Args[2])
	}

	if len(os.Args) > 2 {
		fmt.Println("sunchong", os.Args[1]+os.Args[2])
	}
}

切到这个文件目录下，执行一下：

    go run hello_world.go 1 2

结果是

    Hello World 12
    sunchong 12

单元测试

新建 Test.go 文件

package test

import "testing"

func TestSwitch(t *testing.T) {
	i := 5
	switch i {
	case 1, 2, 3, 4, 5:
		t.Log("yes")
	case 6:
		t.Log("yes2")
	}
}

点击 run test | debug test

输出可爱的结果～～

vscode 输出test结果

有时 vscode 不能输出结果，那么需要进行一下配置：

    文件 -- 首选项 -- 设置 -- 搜索 test 

    工作区设置 -- go test

    这样设置："go.testFlags": ["-v"]

go 代码保存后自动运行单元测试

这样我们可以高效地写我们的单元测试并能快速试错。
