Null-terminated []byte to string doesn't work [closed]

Question

Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.

This question does not appear to be about programming within the scope defined in the help center.

Closed last year.

I have a slice of bytes to represent a null-terminated string with trailing garbage bytes.

I followed How can I convert a zero-terminated byte array to string?

s := string(byteArray[:n])

but it doesn't work

[54 49 0 101 0 0 0 0 64 31 1 0 0]
61e@

instead of just 61

I've also tried to trim the slice: bytes.Trim(buf[:], "\x00") same result.

You have to first find where the 0 is:

ix:=bytes.IndexByte(byteArray,0)
if ix==-1 {
  ix=len(byteArray)
}
s:=string(byteArray[:ix])

I tried to use a method that should do exactly that bytes.Trim(buf[:], "\x00") but it doesn't work.

Trim only removes leading/trailing zeros, in this case, the last two

Too bad there isn't a similar method to trim a slice once a value is found. And what a confusing name bytes.Trim that actually doesn't trim... Thanks! I used your code and it worked.
