Thanks!
I've changed the code to this:
var console *bufio.ReadWriter
var cmd string
func (g *Game) Parse() {
// reader should be wrapped inside an _input() function.
for {
console = bufio.NewReadWriter(
bufio.NewReader(os.Stdin),
bufio.NewWriter(os.Stdout))
fmt.Print(">>> ")
cmd, _ = console.ReadString('\n')
switch cmd {
...
...
Now my thinking is that I should be able to simply assign "cmd" from
anywhere outside the loop
followed by a newline character (i e "cmd = "Test \n") and the reader
should pick it up as if it was a manual input.
Unfortunately, that doesn't quite seem to work yet.
