package regexp
Golang regexp.ReplaceAllFunc() function usage example.
NOTE : The inner function is useful in cases where you need to evaluate certain data first to extract the replacement string.
package main
import (
"fmt"
"regexp"
)
func main() {
// regular expression pattern
regE := regexp.MustCompile("[a-c]*$")
src := []byte("abcdabc")
//repl := []byte("x")
//newByte := regE.ReplaceAll(src, repl)
// NOTE : The inner function is useful in cases where you need to evaluate certain data first
// to extract the replacement string.
// In this example, we will just use string "x" for simplicity sake
newByte := regE.ReplaceAllFunc([]byte(src), func(s []byte) []byte { return []byte("x") })
fmt.Println(string(newByte))
}
Output :
abcdx
