Indenting a text document

The previous recipe depicts how to do string padding and whitespace trimming. This one will guide you through the indentation and unindentation of a text document. Similar principles from the previous recipes will be used.

How to do it...

1. Open the console and create the folder chapter02/recipe12.
2. Create the file main.go with the following content:

         package main

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

         func main() {

           text := "Hi! Go is awesome."
           text = Indent(text, 6)
           fmt.Println(text)

           text = Unindent(text, 3)
           fmt.Println(text)

           text = Unindent(text, 10)
           fmt.Println(text)

           text = IndentByRune(text, 10, '.')
           fmt.Println(text)

         }

         // Indent indenting the input by given indent and rune
         func IndentByRune(input string, indent int, r rune) string {
           return...
