That's normal, line editing on Unix terminals is a kinda advanced 
library feature. The most common lib to do it, GNU readline, is 
actually a big thing that pushed the GPL because of how useful it 
was and it happened to use that license.

I wrote one too though it is a bit bulky.

import terminal;
void main() {
    auto terminal = Terminal(ConsoleOutputMode.linear);
    auto line = terminal.getline("your prompt: ");
    terminal.writeln("You wrote: ", line);
}

compile:

dmd yourapp.d terminal.d
