Golang : Sort lines of text example



Tags : golang sort-lines unstructed-data slice

Here is an example of how to convert lines of text into a slice in Golang, sort them in descending order and then display the sorted output. Can be handy when you need to sort unstructured text data before processing further.

Here you go!


 package main

 import (
 "fmt"
 "sort"
 "strings"
 )

 func sortLines(input string) string {
 var sorted sort.StringSlice

 sorted = strings.Split(input, "\n") // convert to slice

 // just for fun
 //fmt.Println("Sorted: ", sort.StringsAreSorted(sorted))

 sorted.Sort()

 //fmt.Println("Sorted: ", sort.StringsAreSorted(sorted))

 return strings.Join(sorted, "\n")
 }

 func main() {
 text := `stu
 xyz
 def
 abc`

 fmt.Println("Before: ", text)
 fmt.Println("====================================")
 fmt.Println("After: ", sortLines(text))

 }

Before: stu

xyz

def

abc

====================================

After: abc

def

stu

xyz
