How to resolve and expand a relative path to an absolute path using the path package in Golang?

To resolve and expand a relative path to an absolute path using the path package in Golang, you can follow these steps:

Import the necessary packages:

import (
    "path"
    "fmt"
    "os"
)

Define the relative path you want to resolve:

relativePath := "./path/to/file.txt"

Expand the relative path to an absolute path using the path.Join() function, along with os.Getwd() to get the current working directory:

absolutePath := path.Join(os.Getwd(), relativePath)

Print the resolved absolute path:

fmt.Println(absolutePath)

Here's the complete code snippet:

package main

import (
    "path"
    "fmt"
    "os"
)

func main() {
    relativePath := "./path/to/file.txt"
    absolutePath := path.Join(os.Getwd(), relativePath)
    fmt.Println(absolutePath)
}

This code will resolve and expand the relative path to an absolute path and print it to the console.
