Cleaning a string in golang with Buffer and Scanner
I was looking for a while for different ways of cleaning a string in Golang from listed symbols and did find anything fast. Therefore as a regular developer, Iām just reinventing a wheel.
And here is the solution:
func ClearString(str string, symbols []string) string {
scanner := bufio.NewScanner(strings.NewReader(str))
scanner.Split(bufio.ScanRunes)
var buf bytes.Buffer
out:
for scanner.Scan() {
t := scanner.Text()
for _, s := range symbols {
if s == t {
continue out
}
}
buf.WriteString(scanner.Text())
}
return buf.String()
}Benchmarking
