Go read input from user with NewScanner

In the example, we will show you how to read input from a user with NewScanner in the Go language.

Go read input from user with NewScanner

The Scanner provides a convenient interface for reading data such as a file of newline-delimited lines of text. 


package main

import (
    "bufio"
    "fmt"
    "os"
)

func main() {

    names := make([]string, 0)

    scanner := bufio.NewScanner(os.Stdin)
    
    for {
        fmt.Print("Enter name: ")
        
        scanner.Scan()
        
        text := scanner.Text()

        if len(text) != 0 {

            fmt.Println(text)
            names = append(names, text)
        } else {
            break
        }
    }

    fmt.Println(names)
}

Output: 

G:\GoLang\examples>go run go_example.go
Enter name: John
John
Enter name: Tony
Tony
Enter name: Tom
Tom
Enter name:
[John Tony Tom]

Note: The example allows to read multiple names from the user. Press enter without value to finish the program.
