How Can I Send Keystrokes to a Channel Without Requiring a Newline?

Sending Keystrokes to Channel Without Newline Requirement

This question aims to explore the challenge of directly sending user keystrokes to a channel as they are entered into stdin, without the need for a newline character. The provided code attempts this but faces a limitation: the reader.ReadByte() method waits for a newline before proceeding.

The solution lies in understanding that stdin is typically line-buffered by default. This prevents the immediate yielding of input until a newline is encountered, a characteristic not unique to Go.

To achieve the desired behavior, platform-specific solutions are required. One option is to use the ncurses library, which provides a way to handle non-buffered input. Another alternative is the lightweight go-termbox package.

However, if a fully manual approach is preferred, one can delve into C bindings for termios or directly use Go syscalls on Linux systems. How Windows handles this remains unclear but can be explored through the source code of ncurses or termbox.
