It's "Lua".

I quickly wrote a small module using curses, which uses this function:
static int lua_getch( lua_State *L ) {
initscr();
cbreak();
int i = getch();
lua_pushinteger( L, i );
endwin();
return 1;
}
(no error checking). Unfortunately, this clears the screen, which may
not be what you want to do. As this seems to be a common problem, I'd
be glad to hear of a solution.
On Windows, you can use _getch() from conio.h to do this (without
clearing the screen).
