OSX is the new name for Apple's OSes: Mac OS X and iPhone OS.
And of course DMD can use anything, but GDC uses darwin/Unix.
Apple can't seem to make up their mind. uname does return "Darwin". gcc
predefines "__MACH__" and "__APPLE__", but neither darwin nor osx. The
documentation all says osx.
Will you set version(darwin) though, or would that be "version(osx)" ?
The existing D code for Mac OS X all uses version(darwin) from before.
version(OSX)
I just don't think darwin is a good idea, as Apple doesn't even use it.
See http://developer.apple.com/unix/index.html, where "darwin" is clearly
second string. It looks like Apple is pushing aside "darwin" in favor of
"OSX".
I'm not going to argue about what is the best version identifier for Mac
OS X, the I only thing I care about is consistency and "darwin" is already
used by LDC and GDC. Don't make things harder.
Fortunately, (darwin) => (OSX) is a trivial global search/replace.
And I assume it's equally trivial to implement "darwin" as the version
identifier. Again, don't make things harder by breaking existing code.
I don't have an opinion on the correct identifier to use, but not
implementing a change that makes something more correct *just* because it
breaks existing code (particularly in an easy-to-fix way) is a terrible
strategy. That's exactly what's turned C++ into the abysmal mess that it is
today, which in turn is one of the primary reasons for D's existence. I
don't want to end up with yet another C++.
I guess I have to start to argue. In this case I don't see that some
version identifier is more correct than the other, you just have to make
a choice. Either you choose to be as close to the official name of the
operating system as possible, in this case I guess it should be "Mac OS
X". Or you choose the uname that I've seen some people here talk about
or a part of the target triple or what it's called, for example
i386-apple-darwin. Then there's the question about upper/lowercase and
spaces in the name. Or any other suggestions.
I have know idea what the initial thought was when Walter chose the
version identifiers and therefore I have no idea what would be the most
correct version identifier to choose in this case.
Because of gdc and ldc already use "darwin" you have to make a special
case for dmd. Of course they could change the version identifier but at
least for gdc I don't see that's very likely. GDC seems quite dead but
it's still the most reliable compiler for Mac OS X at this point. I have
no problem using dmd when it becomes equally reliable on Mac OS X as on
linux/windows but as far as I know it will only be for x86 and there are
three other targets for osx (excluding iphone): x86-64, ppc and ppc64.
So what is the most correct version identifier? I don't know. But I
think you should choose one option form the beginning and then try to be
as consistent as possible.
I guess I have to add this to every dsss file:
version (DigitalMars)
version (OSX)
version = darwin
