Adding a space between uppsercase letters

I have string like this ClientLovesProcess I need to add a space between each uppercase letter except for the first uppercase letter so the end result would be this Client Loves Process

I don't think golang has the best string support but this is how I was thinking about going about it:

First loop through each letter so something like this:

name := "ClientLovesProcess"

wordLength := len(name)

for i := 0; i < wordLength; i++ {
	letter := string([]rune(name)[i])

    // then in here I would like to check
   // if the letter is upper or lowercase

   if letter == uppercase{
       // then break the string and add a space
   }
}

The issue is I don't know how to check if a letter is lower or uppercase in go. I checked the strings manual but they don't some to have a function for it. What would be another approach to get this done with go?

The function you're looking for is unicode.IsUpper(r rune) bool.

I would use a bytes.Buffer so that you're not doing a bunch of string concatenations, which results in extra unnecessary allocations.

Here's an implementation:

func addSpace(s string) string {
	buf := &bytes.Buffer{}
	for i, rune := range s {
		if unicode.IsUpper(rune) && i > 0 {
			buf.WriteRune(' ')
		}
		buf.WriteRune(rune)
	}
	return buf.String()
}

And a play link.

You can test for upper case with the unicode package. This is my solution:

playground

package main

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

func main() {
	name := "ClientLovesProcess"
    newName := ""
	for _, c := range name {
	   
		if unicode.IsUpper(c){
		    newName += " "   
		}
		newName += string(c)
	}
	newName = strings.TrimSpace(newName) // get rid of space on edges.
	fmt.Println(newName)
}
