Hello.  Here's a short program that works in a dos window:

import std.stdio;

void main() {

  writef( "What is your name?");

  string name = readln();
  writefln( "Hello " ~ name);
}

The program prints a prompt without a newline and the user enters a name and a greeting is printed.

The same program does not seem to work when at a cygwin prompt.  The program
seems to pause.  It is actually waiting for input.  So, if I type in a name
and hit return, the prompt and the greeting appears as expected but on one line.

I can change writef to writefln and it will work on the cygwin prompt and on the dos prompt, but now a newline will be added after the prompt message.

I'm wondering how can I fix this?  I am using bash shell on cygwin.


thanks.

try flushing the output after the write: stdout.flush();
