digitalmars.D.learn - std.system reports win32 when running OS X

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.
   writefln("OS = %s",os);
 }
What you need is the already defined std.system.os: import std.stdio; import std.system; void main (string[] args) { writefln("OS = %s",os); } Ali

:) 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. Dave
