Hi! I was tackling a similar problem and creack's pty might be a bit too abstracted for what you want. I just used the golang standard xterm terminal emulator https://pkg.go.dev/golang.org/x/term and a pipe.

Hi! I was tackling a similar problem and creack's pty might be a bit too abstracted for what you want. I just used the golang standard xterm terminal emulator https://pkg.go.dev/golang.org/x/term and a pipe.

Here's a partial snippet as an example of what I mean. Your stdin stream is fed into the stdin_writer and your stdout is written to the writer, don't forget to Flush()!

stdin_reader, stdin_writer := io.Pipe()
reader := bufio.NewReader(stdin_reader)

stdout_writer := bytes.Buffer{}
writer := bufio.NewWriter(&stdout_writer)

rw := bufio.NewReadWriter(reader, writer)
t := term.NewTerminal(rw, prompt)

// constantly be reading lines
go func() {
	for {
		line, err := t.ReadLine()
		if err == io.EOF {
			log.Printf("got EOF")
		}
		if err != nil {
			log.Printf("got err")
		}
		if line == "" {
			continue
		}
		log.Printf("LINE: %s", line)
	}
}()
