Golang language learning day 1_Installation environment configuration and development tools

1. Local debugging

1、Go Demo

package main

import (
	"flag"
	"fmt"
)

// 声明输入参数hxpInputParam 默认值为0 用途描述
var hxpInputParam = flag.Int("hxpInputParam", 0, "Input parameter for 珩小派")

func main() {
	fmt.Println("珩小派-本地调试，配置演示开始")
	//解析命令行参数并设置相应的标志变量
	flag.Parse()
	var x = 5
	fmt.Println("The value of x is：", x)
	// 两数相加
	sum := *hxpInputParam + x
	fmt.Println("The sum of add x and hxpInputParam is:", sum)
	fmt.Println("珩小派-本地调试  End!")
}

2、GoLand Run/Debug Configurations

Final output

珩小派-本地调试，配置演示开始
The value of x is： 5
The sum of add x and hxpInputParam is: 55
珩小派-本地调试  End!      

2. Attach to process

1、Go Demo

package main

import (
	"flag"
	"fmt"
	"time"
)

var hxpInputParam1 = flag.Int("hxpInputParam1", 0, "Input parameter for 珩小派")

func main() {
	flag.Parse()
	var i = 0
	for {
		fmt.Println("print", i, *hxpInputParam1)
		i++
		time.Sleep(time.Second)
	}
}

2. Install gops plug-in

Execute the following command

go install github.com/google/gops@latest Plug-in installed successfully

GoLand-Run-Attach to Process
