import terminal;

void main() {
    auto terminal = Terminal(ConsoleOutputType.linear); // I think I changed ConsoleOutputType from some thing else that didn't work
    auto line = terminal.getline("your prompt: ");
    terminal.writeln("You wrote: ", line);
}

Huh, that should work unless your terminal is outrageously narrow or maybe output starting on the right side of the screen already.

But I can't look much further without having a mac myself, could be a few other causes :(

Maybe you can try gnu readline instead:


extern(C) char* readline(const(char)* prompt);
pragma(lib, "readline");
pragma(lib, "curses");
void main() {
        auto line = readline("your line: ");
        import std.stdio, std.conv;
        writeln(to!string(line));
}

Thanks Adam. That works better than normal. Up and down don't work though.

There's another function called add_history for that. Readline is a pretty popular library (also GPL though, keep that in mind if you distribute your program, it must also be GPL if you use it) so you can find more info on the net:

http://web.mit.edu/gnu/doc/html/rlman_2.html


Basic thing is if you want to add it to history, call add_history(ptr_it_returned); and it will then be available for up/down access.

Also, readline is a C library, so it does expect you to free the memory it allocates too.... but you can probably just let that slide, it'll be fairly small leaks all things considered.


If I can ever actually get access to a Mac, I'll try to debug my other lib on one too.
