Hello,
in order to have correctly displayed output (before reading
something from stdin),
I must call stdout.flush().
Sometimes, it's really annoying, especially when it is
necessarry to
call it 10 times.
For example:
write("Enter some string: ");
stdout.flush();
string a = readln();
write("And again please: ");
stdout.flush();
string b = readln();
...
Is there any way to prevent this?
What about:
void prompt(A...)(string fmt, A args)
{
writef(fmt, args);
stdout.flush();
return readln();
}
auto a = prompt("Enter your name: ");
auto b = prompt("Enter your age: ").to!int;
... // etc.

Thanks, I didn't think about that (I'm beginner)
