How to use the strconv.Unquote() function in Golang

The strconv.Unquote() function

The strconv package’s Unquote() function is used to read the given string s as a single-quoted, double-quoted, or backquoted string and return the string value that s quotes.

Syntax

func Unquote(s string) (string, error)

Parameter

  • s: This is the value of the quoted string from which the string is obtained.

Return value

The Unquote() function returns the string value quoted by the specified string s.

Note: The Unquote() function returns the equivalent one-character string if there is a single-quoted string.

Code

The following code shows how to implement the strconv.Unquote() function in Golang.

// using strconv.Unquote() Function in Golang
package main
import (
	"fmt"
	"strconv"
)
func main() {
  	// declare variable s, err and assign value to it
	s, err := strconv.Unquote("`Golang is one of my favourite programming languages`")
	// display result
	fmt.Printf("The value for s: %q, and error: %v\n", s, err)
	// reassigning value to s, err
	s, err = strconv.Unquote("Golang is one of my favourite programming languages")
	// display result
	fmt.Printf("The value for s: %q, and error: %v\n", s, err)
}

Explanation

  • Line 4: We add the main package.
  • Lines 6–9: We import the necessary packages for the Golang project.
  • Lines 10–21: We define the main() function.
  • Line 13: We define the variables s and err, pass a value to the Unquote() function, and assign it to the variables.
  • Line 20: We print the results.

Note: If the value of s is syntactically valid, then the error will be <nil>.
