Nice touch for adding write and writeln to std.stdio: naming consistency is important indeed.

Thanks,

And to think I just patched some code and makefiles last night to work around some of these bugs :-)  Nice work!

On a semi-related note, a Tango release is planned for today.  In fact, it's already packaged and ready to go.  So I'll give DMD 1.022 support a look this evening and perhaps we'll re-release tomorrow if any changes are necessary.  I have jury duty so I won't be able to get to it today.

neat!
maybe the docs for c++ interfacing should mention, that it requires a compatible c++ compiler to work (DMC or MSVC on windows and GCC 3.x on linux?).

C++, coool.

--Typo from http://www.digitalmars.com/d/cpp_interface.html

	Use the limited ability described here to
	connect directly to C functions and classes.

that should be c++ functions and classes.

Got it.

Don't know what you mean.

> --Is dmc going to get an "extern(D)" extension?

No. My experience with C++ extensions is that people won't use them, so they're a waste of time. There are other problems, too, like C++ has no notion of a module, so where's the D module name going to come from?

will this work?

extern(c++)
{
	int Foo(int i);
	int Foo(int* ip);
}

void bar()
{
	int i;
	Foo(i);
	Foo(&i);
}


What about if there is a

void Foo(int[] ia){...} // non extern(c++)

Will that overload with the c++ functions?

Can D define overloaded extern(c++) function for C++ to link with?

Shucks.

Use a capital C.

Yes.

Yes. Just remember that the selection of function will follow D overloading rules, not C++ rules, even if the functions are labeled extern(C++).

> Can D define overloaded extern(c++) function for C++ to link with?

Yes.

In addition to better organized, over the next several releases of the 2.x compiler and it's associated runtime and phobos libraries, you can expect to see incremental work towards rationalizing a number of the differences between dmd's phobos, gdc's phobos, and tango's compiler runtime layers for dmd and gdc.

I'm not committing to a specific order or timeline at this point, just that the work has started.  The unittest fixes in this release were a direct result of me getting my hands dirty.

More soon,
Brad

I've noticed a few things about cpp_interface.html:

1. `Strings are not 0 terminated in D. See "Data Type Compatibility" for more information about this. However, string literals in D are 0 terminated.`

However, there's nothing specific about strings in the referenced section.

2. In Data Type Compatibility:

no equivalent   type &

Is ref type not the D equivalent of this?

3. How about making it so that D dynamic array parameters become, on the C++ side, two parameters: length and pointer?
