Golang : Humanize and Titleize functions



Tags : golang humanize convert titleize

Humanize function takes multiple words separated by a given separator and changes them to spaces. Titleize converts a given string into a proper title with each word starting character in upper case.

Here you go!


 package main

 import (
 "fmt"
 "strings"
 "unicode"
 )

 func Titleize(input string) (titleized string) {

 isToUpper := false

 for k, v := range input {
 if k == 0 {
 titleized = strings.ToUpper(string(input[0]))
 } else {
 if isToUpper || unicode.IsUpper(v) {
 titleized += " " + strings.ToUpper(string(v))
 isToUpper = false
 } else {
 if (v == '_') || (v == ' ') {
 isToUpper = true
 } else {
 titleized += string(v)
 }
 }
 }
 }
 return

 }

 func Humanize(input string, separator string) (humanized string) {
 // Takes multiple words separated by the separator and changes them to spaces

 for k, v := range input {
 if k == 0 {
 humanized = strings.ToUpper(string(input[0]))
 } else {
 if string(v) == separator {
 humanized += string(" ")
 } else {
 humanized += string(v)
 }
 }
 }
 return

 }

 func main() {

 // separator is _, convert to spaces
 fmt.Println(Humanize("the_big_boss", "_"))

 // separator is already spaces
 fmt.Println(Humanize("big boss", " "))

 // separator is +
 fmt.Println(Humanize("big+boss", "+"))

 fmt.Println(Titleize("nab that guy"))
 fmt.Println(Titleize("NabThatGuy"))
 fmt.Println(Titleize("space-marinesKillAliens"))
 fmt.Println(Titleize("raiders_of_the_lost_ark"))
 }

Output:
