I am running an iMac with OS X 10.11.5 (El Capitan) and dmd version 2.072.2
The following program prints out OS = win32.

Is this the intended behavior?

#!/usr/local/bin/rdmd

import std.stdio;
import std.system;

void main (string[] args) {
  immutable OS os;
  writefln("OS = %s",os);
}

That's a local variable that you've defined. Since OS.init happens to be OS.win32, that's what you get.

What you need is the already defined std.system.os:

import std.stdio;
import std.system;

void main (string[] args) {
  writefln("OS = %s",os);
}

:)

Maybe it should be "unknown" or "undefined" :)

You can always make a pull request for that and then see if everybody agrees or if there's a specific reason why it initializes to Windows.

Ali,
Thank you. I've got it working.
I had to use writefln("OS = %s",std.system.os); to get it to compile.
