February 05, 2016

Count leading spaces of a string in Golang.

Run code on Go Playground

package main

import "fmt"

func countLeadingSpace(line string) int {
        i := 0
        for _, runeValue := range line {
                if runeValue == ' ' {
                        i++
                } else {
                        break
                }
        }
        return i
}

func main() {
        fmt.Println(countLeadingSpace("0 space"))
        fmt.Println(countLeadingSpace(" 1 space"))
        fmt.Println(countLeadingSpace("  2 space"))
        fmt.Println(countLeadingSpace("   3 space"))
}
