bytes package
SplitAfter slices the input slice into all subslices after each instance of separator(2nd parameter) and returns a slice of those subslices. If separator is empty, SplitAfter splits after each UTF-8 sequence. It is equivalent to SplitAfterN with a count of -1.
Golang bytes.SplitAfter() function usage example
package main
import (
"fmt"
"bytes"
)
func main() {
str := []byte("I LOVE THIS WORLD!")
for i, rune := range bytes.SplitAfter(str, []byte{'L'}) {
fmt.Printf("Counter %d : %s\n", i , string(rune))
}
fmt.Println("--------------")
for i, rune := range bytes.SplitAfter(str, []byte{'T'}) {
fmt.Printf("Counter %d : %s\n", i , string(rune))
}
fmt.Println("--------------")
for i, rune := range bytes.SplitAfter(str, []byte{}) {
fmt.Printf("Counter %d : %s\n", i , string(rune))
}
}
Output :
Counter 0 : I L
Counter 1 : OVE THIS WORL
