Golang : Find the shortest line of text example

Continue from previous tutorial on how to find the longest line in a given text. This example demonstrates how to find the shortest line in a given text file. Can be useful in a situation where you want to find shortest lines to discard from a raw data file.

Here you go!

 package main

 import (

 func shortestLine(input string) (shortest string) {
 lines := strings.Split(input, "\n")

 size := len(lines[0]) // init with first line length

 for _, v := range lines {
 //fmt.Println(k,v, "Size: ", len(v))

 if len(v) <= size {
 shortest = v
 size = len(v)

 func main() {
 text := `line 1
 line 2 line 3 line 4
 line 5 line 6 line 7 line 8 line 9 line 10
 line 11 line 12
 line 13 line 14 line 15


 // find the shortest line in text and display it
 fmt.Println("Shortest: ", shortestLine(text))

Shortest: no!
