Let's say I want to write a simple program that asks for an

After pressing a single key on a keyboard, the character is
printed out and the program should stop.
This is platform specific. About 10 lines of code for a minimum
implementation per OS, but if you don't wanna do it that way my
library has a function for it with a prepackaged sample:
http://arsd-official.dpldocs.info/arsd.terminal.html#single-key
that's arsd-official:terminal on dub or you can grab the file
from my github repo.
I guess you could view my source to see the impl but I don't
feel like pulling it out right now.
Thanks Adam.
I've tested and it does work on Windows 10.
mkdir "read_character_project"
cd "read_character_project"
dub init
dub add arsd-official:terminal
notepad ./source/app.d
import arsd.terminal;
void main() {
auto terminal = Terminal(ConsoleOutputType.linear);
auto input = RealTimeConsoleInput(&terminal,
ConsoleInputFlags.raw);
terminal.writeln("Press any key to continue...");
auto ch = input.getch();
terminal.writeln("You pressed ", ch);
}

Of interest, I also tried to look up getch() inside
http://arsd-official.dpldocs.info/source/arsd.terminal.d.html#L2867
But the source file overwhelmed me by its size.
For now I'm still interested in a more simple standalone
implementation that would be more learning friendly, or at least
with little explanation of basic things behind the code and how
it is interfacing with the operating system, the native library.
