package main
import (
"fmt"
"strings"
)
func removeCharacters(input string, characters string) string {
filter := func(r rune) rune {
if strings.IndexRune(characters, r) < 0 {
return r
}
return -1
}
return strings.Map(filter, input)
}
func main() {
str := "你好吗? 我好! 好我好!? 你好好!"
stripped := strings.Replace(str, "我好", "", -1) // Replace will work with a single unicode
fmt.Println("Before : ", str)
fmt.Println("After : ", stripped)
str = "Happy Go Lucky!"
stripped = strings.Replace(str, "a", "", -1) // only works with a single character
fmt.Println("Before : ", str)
fmt.Println("After : ", stripped)
str = "Happy Go Lucky!"
stripped = strings.Replace(str, "aGo", "", -1) // but NOT with a set of characters
fmt.Println("Before : ", str)
fmt.Println("After : ", stripped)
fmt.Println("-------------------------------------------------")
str = "你好吗? 我好! 好我好!? 你好好!"
stripped = removeCharacters(str, "我好") // now with remove/strip a set of unicode characters
fmt.Println("Before : ", str)
fmt.Println("After : ", stripped)
str = "Happy Go Lucky!"
stripped = removeCharacters(str, "aGo") // will work with a set of characters
fmt.Println("Before : ", str)
fmt.Println("After : ", stripped)
}
Output:
Before : 你好吗? 我好! 好我好!? 你好好!
After : 你好吗? ! 好!? 你好好!
Before : Happy Go Lucky!
After : Hppy Go Lucky!
Before : Happy Go Lucky!
After : Happy Go Lucky!
Before : 你好吗? 我好! 好我好!? 你好好!
After : 你吗? ! !? 你!
Before : Happy Go Lucky!
After : Hppy Lucky!
