golang scan a line of numbers from sdin

I'm trying to read input from stdin like

3 2 1<ENTER>

and save it in a list of ints. At the moment my code looks like this:

nums = make([]int, 0)
var i int
for {
    _, err := fmt.Scan(&i)
    if err != nil {
        if err==io.EOF { break }
        log.Fatal(err)
    }
    nums = append(nums, i)
}

at the moment the program never leaves the for-loop. I can't find an easy way to check for a newline character in the documentation. how would i do this?

Edit:

Since I know that there will almost certainly be four numbers, I tried the following:

var i0,i1,i2,i3 int
fmt.Scanf("%d %d %d %d\n", &i0, &i1, &i2, &i3)

but this only scanned the first number and then exited the program. I'm not sure if that's because of the z-shell I'm using.

Edit:

To clarify, the program will pause and ask for the user to input a list of n numbers separated by spaces and terminated with a newline. these numbers should be stored in an array.

Ok, I decided to bring out the large bufio hammer and solve it like this:

in := bufio.NewReader(os.Stdin)
line, err := in.ReadString('\n')
if err != nil {
    log.Fatal(err)
}
strs := strings.Split(line[0:len(line)-1], " ")
nums := make([]int, len(strs))
for i, str := range strs {
    if nums[i], err = strconv.Atoi(str); err != nil {
        log.Fatal(err)
    }
}

It does seem like an awful lot of code, but it works.

It seems that you want https://golang.org/pkg/fmt/#Fscanln

Something like

ok := func(err error) { if err != nil { panic(err) } }

for {
  var i, j, k int
  _, err := fmt.Fscanln(io.Stdin, &i, &j, &k)
  ok(err)
  fmt.Println(i, j, k)
}

I will suggest to use "bufio" package with the "scan()" method.
Following is the code where I'm reading two lines from "stdin" and storing the lines into an array.
Hope this helps you.

package main

import (

    "fmt"
    "bufio"
    "os"
    "strconv"
    "strings"
)

func ReadInput() []string{

    var lines []string
	scanner := bufio.NewScanner(os.Stdin)

    for scanner.Scan() {
	    lines = append(lines, scanner.Text())
        //count, _ := strconv.Atoi(lines[0])
		if len(lines) == 2 { break }
    }
	if err := scanner.Err(); err != nil {
	fmt.Fprintln(os.Stderr, err)
	}
	return lines
}
  
func main(){

	lines	:= ReadInput()
	count ,_ := strconv.Atoi(lines[0])
	num := strings.Fields(lines[1])
	if count != len(num) { os.Exit(0) }
 // Do whatever you want here
}

Two lines will be accepted. First line will have a count. Second line will have all the numbers. You can modify the same code as per your requirement.

Example:

3
1 5 10
