It is a lightweight and simple port of the textwrap Python module.

Soli Deo gloria

Features:

• Lightweight. Uses only the Go built-in library (no external deps).
• Simple. Easy to understand code.
• Counts number of words and characters.
• Splits (or groups) text based on character limit (width) per group (each wrap).
• 100% test coverage.
• GoDoc documentation

It was only designed to work with English text; it separates words by whitespace.

import (
 "fmt"
 "textwrap"
)
origText := "Jesus is God. He Saves by grace through faith alone."
result, err := textwrap.WordWrap(origText, 10, -1)
if err != nil {
 // handle error
}
// check if max word count exceeded
if result.IsValid() {
 // print text groups
 for idx, text := range result.TextGroups {
 fmt.Println("[", idx+1, "]", text)
 }
}
