Golang : Escaping single quotes

Question

Is there a way to escape single quotes in go?

The following:

str := "I'm Bob, and I'm 25."
str = strings.Replace(str, "'", "\'", -1)

Gives the error: unknown escape sequence: '

I would like str to be

"I\'m Bob, and I\'m 25."

You need to ALSO escape the slash in strings.Replace.

str := "I'm Bob, and I'm 25."
str = strings.ReplaceAll(str, "'", "\\'")

Even the first string can be in backquote. In my case i had to replace \" with " in my dbjson variable dbjson = strings.Replace(dbjson, \`\"\`, \`"\`, -1) This answer helped me to get there :) – deepakssn May 21 '17 at 05:53

// addslashes()
func Addslashes(str string) string {
    var buf bytes.Buffer
    for _, char := range str {
        switch char {
        case '\'':
            buf.WriteRune('\\')
        }
        buf.WriteRune(char)
    }
    return buf.String()
}

Probably best to use `var buf strings.Builder` (instead of `bytes.Buffer`) in this case. It has the same methods, so no other changes needed – ardnew Jan 19 '22 at 19:15

strings.Replacer can be used to escape a number of different characters at once. Also handy if you want to reuse the same logic in different places.

quoteEscaper := strings.NewReplacer(`'`, `\'`, `"`, `\"`)
str := `They call me "Bob", and I'm 25.`
str = quoteEscaper.Replace(str)
