How can I read from standard input in the console?

Question

I would like to read standard input from the command line, but my attempts have ended with the program exiting before I'm prompted for input. I'm looking for the equivalent of Console.ReadLine() in C#.

This is what I currently have:

package main  import (     "bufio"     "fmt"     "os" )  func main() {     reader := bufio.NewReader(os.Stdin)     fmt.Print("Enter text: ")     text, _ := reader.ReadString('\n')     fmt.Println(text)      fmt.Println("Enter text: ")     text2 := ""     fmt.Scanln(text2)     fmt.Println(text2)      ln := ""     fmt.Sscanln("%v", ln)     fmt.Println(ln) } 

Answer 1

I'm not sure what's wrong with the block

reader := bufio.NewReader(os.Stdin) fmt.Print("Enter text: ") text, _ := reader.ReadString('\n') fmt.Println(text) 

As it works on my machine. However, for the next block you need a pointer to the variables you're assigning the input to. Try replacing fmt.Scanln(text2) with fmt.Scanln(&text2). Don't use Sscanln, because it parses a string already in memory instead of from stdin. If you want to do something like what you were trying to do, replace it with fmt.Scanf("%s", &ln)

If this still doesn't work, your culprit might be some weird system settings or a buggy IDE.

You can as well try:

scanner := bufio.NewScanner(os.Stdin) for scanner.Scan() {     fmt.Println(scanner.Text()) }  if scanner.Err() != nil {     // Handle error. }
