bufio.NewReader总是创建一个新行：/

I use this, to collect a input and display the input then, but when I do it like this the "something" text will be displayed in a new line, but I want the text to be displayed in the same line, any ideas?

func main() {
    fmt.Println("Example")
    print("example: ")
    in := bufio.NewReader(os.Stdin); 
    input, err := in.ReadString('
');
    if err != nil {
        fmt.Println("Error: ", err)
    }

    fmt.Println(input, "something")
}

fmt.Println() automatically appends a newline to the end of it's output.

You could try using Printf, which takes a "format string" and a list of inputs.

An example would be:

func main() {
  fmt.Println("Example")
  print("example: ")
  in := bufio.NewReader(os.Stdin); 
  input, err := in.ReadString('
');
  if err != nil {
      fmt.Println("Error: ", err)
  }

  fmt.Printf("something : %s", input)
}

In this case, %s is a placeholder for a string type. All the placeholders can be found in the fmt godoc: http://golang.org/pkg/fmt/

Also if the input itself has a newline at the end, you can use Trim from the package strings to pull off the character.

Trim the newline from input. For example,

package main

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

func main() {
    fmt.Println("Example")
    print("example: ")
    in := bufio.NewReader(os.Stdin)
    input, err := in.ReadString('
')
    if err != nil {
        fmt.Println("Error: ", err)
        return
    }
    fmt.Println(strings.TrimRight(input, "
"), "something")
}

Input/Output:

Example
example: some input
some input something

On windows (not sure if that is relevant) none of the previous answers worked for me. So here's the resolution I found on: https://groups.google.com/d/msg/golang-nuts/hWoESdeZ398/qDbTogJhj88J which links to https://play.golang.org/p/_9N_RwmBvd

The basic idea is that rather than using strings.TrimRight(input, " ") you would include a character, like strings.TrimRight(input, " ")
This fixes the OPs issue.

OP code with fixed input stripping!

func main() {
    fmt.Println("Example")
    print("example: ")
    in := bufio.NewReader(os.Stdin); 
    input, err := in.ReadString('
');
    if err != nil {
        fmt.Println("Error: ", err)
    }

    fmt.Println(strings.TrimRight(input, "
"), "something")
}

PS: Sorry for the necro I'm just hoping to save someone from wasting 20 minutes googling!
