Title Body

To teach myself Go I'm building a simple server that takes some input, does some processing, and sends output back to the client (that includes the original input). The input can vary in length from around 5 - 13 characters + endlines and whatever other guff the client sends. The input is read into a byte array and then converted to a string for some processing. Another string is appended to this string and the whole thing is converted back into a byte array to get sent back to the client. The problem is that the input is padded with a bunch of NUL characters, and I'm not sure how to get rid of them. So I could loop through the array and when I come to a nul character, note the length (n), create a new byte array of that length, and copy the first n characters over to the new byte array and use that. Is that the best way, or is there something to make this easier for me? Some stripped down code: data := make([]byte, 16) c.Read(data) s := strings.Replace(string(data[:]), "an", "", -1) s = strings.Replace(s, "\r", "", -1) s += "some other string" response := []byte(s) c.Write(response) c.close() Also if I'm doing anything else obviously stupid here it would be nice to know.
