Debug Golang with VSCode

Example

Create a simple go lang file with the below code:

• main.go

package main

import (
	"fmt"
	"os"
	"strings"
)

func main() {
	fmt.Println("hello world")

	name := os.Args[1:]

	fmt.Println("hello " + strings.Join(name, ""))
}

Make sure the go.mod is initialized

• go.mod

module test-debug

go 1.19

it will print the args from the command-line args

Switch to the Run and Debug

And choose the create a launch.json file and fill in the config for debugging

The config example is below:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${fileDirname}",
            "args": ["nick","ben"]
        }
    ]
}

the args are the arguments you want to put after the go program, for example:

go run main.go nick ben

then the “args“ is:

"args": ["nick","ben"]

Now you can start your debugging
