go get github.com/speedata/hyphenation
Download a hyphenation pattern file from CTAN, for example from https://ctan.math.utah.edu/ctan/tex-archive/language/hyph-utf8/tex/generic/hyph-utf8/patterns/txt/
package main
import (
"fmt"
"log"
"os"
"github.com/speedata/hyphenation"
)
func main() {
filename := "hyph-en-us.pat.txt"
r, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
l, err := hyphenation.New(r)
if err != nil {
log.Fatal(err)
}
var h []int
for _, v := range []string{"Computer", "developers"} {
h = l.Hyphenate(v)
fmt.Println(v, h) // [3 6] and [2 5 7 9]
}
}Similar to getting the hyphenation slice, you can get a detailed view of the hyphenation patterns used in a word:
str := l.DebugHyphenate("developers")
fmt.Println(str)results in
. d e v e l o p e r s .
