Input Keystrokes Directly to Channel without Newline
In Go, standard input (stdin) is line-buffered by default. This implies that keystrokes are not immediately sent to a channel; instead, they are held until a newline character is inputted. To overcome this limitation, here's how you can read keystrokes and send them to a channel without the need for a newline:
<code class="go">func chars() <-chan byte { ch := make(chan byte) reader := bufio.NewReader(os.Stdin) go func() { for { char, err := reader.ReadByte() if err != nil { log.Fatal(err) } ch <- char } }() return ch }</code>
However, stdin line buffering is not specific to Go but rather a platform-wide default. For non-buffered input, platform-specific solutions are required. One option is to use the ncurses or go-termbox packages. Alternatively, you can implement manual input handling with termios or Go syscalls (for Linux). Windows implementation requires exploration of ncurses or termbox source code.
