Standard c wide strings

[Eric VERGNAUD]

Hello,

I'm having trouble trying to include standard C++ headers for wide
characters, such as wcslen, iswupper etc... In Project Builder.

I cannot find <whar.h> anywhere else than in CW headers.

Isn't the standard C++ library supported by PB ?

Thanks,

Eric

wchar.h is not supported in Jaguar. You're encouraged to use the Core
Foundation string APIs instead, which work far better than the wchar
APIs.

Oh well...

Is Apple going the bad way again ?

I don't care much about the underlying implementation, but why don't they
simply provide a set of files that do the job, so that our source can be
cross-platform ?

One of us is confused. The standard C++ library support for wide
character strings is the same as the support for 8-bit characters:

std::string is defined as:

typedef basic_string<char, char_traits<char>, allocator<char> > string;

and std::wstring is defined as:

typedef basic_string<wchar_t, char_traits<wchar_t>, allocator<wchar_t> >
wstring;

All of the functions you've listed (wcslen, iswupper etc ) are C legacy
functions that you shouldn't need to use in C++.

Morever functions like iswupper depend on the locale, because a wstring
just specifies a character width, not a character encoding. (You can't
tell if the character 0x203E is upper case or not unless you also
specify something like: the wstring is in UCS-2.)

Well, they haven't provided them yet, but that doesn't preclude Apple
from providing them in the future. Perhaps they'll be part of a future
OS release.

Well I do, as C functions. The fact that they rely on the underlying locale
makes them just perfect for the common use.

No, they aren't.

No, they don't seem to consider it a problem.

Yes, it's annoying, especially because it's a C standard,
in spite of the fact that neither the Windows nor the Linux
implementations are fully compliant with the standard.

And it's doubly annoying, because wchar_t is defined, and
it's a 32-bit integer, whereas the Mac stuff uses UTF-16.

And I've had to make my own equivalence library.

No, I can't release it, becaue that was under a contract
job.

But it sounds like a good free software project.

Instead of Project Builder, you might consider CodeWarrior which has a
more conforming C library than Apple's.

Thanks, I'm using CW 99% of the time on Mac. However, 8.3 doesn't support
Objective-C, and 9 doesn't support Java. So I switched to PB for a small
Cocoa bundle.

Thanks

8.3 does support Objective-C, but only minimally. That is, it compiles
quite fine, but there is no syntax colouring, function popup, etc. that
does make it somewhat of a pain.

Certainly CW 9 supports Objective C (as well as ObjC++) we've had it
before OS X was out.

Thanks, I've moved back to CW anyway. GCC is so sloooow, that I just can't
get used to it.
