I hear some people want to hook up a C++ engine to a Python game core.  I'd
rather just write the whole thing in D, and I don't see why we can't come up
with something that powerful.

 Walter, your exception stuff shows up very wierd in the Visual Studio .NET
 debugger.  ;)

Hmm. Try windbg.exe with it (comes on the Digital Mars CD).
 Any chance you can insert some line number info inside of the app's D

 All I get is RTL stuff.  ;)

Compile with -g and line number info should be inserted.
 Lots of cleanup I see has been done to the Windows.d.  Lots more left to

 also. hehehe  Do you want my winbase.d, wingdi.d, and winuser.d?  They

 in a few holes in Win32 support.  I'm sure nobody else wants to declare
 their own winapi stuff anymore than they have to.

 Until then I'm not sure what's crashing.  I'll go poke around on the stack
 for a bit and see what I can come up with.

Ok, but if there's a bug in D I need a test case so it can be fixed.
 If I can get a good D testbed going with good debugger integration I think

 can get some use out of it.  C# doesn't suit me I don't think but I really
 hate C++ lately so doing my own stuff in it seems like a chore.  I'd

 code in D at this point I think.  But D has a ways to go before it will be
 usable for my main line of work for a while.  C++ is the only viable
 alternative for games work right now.  Other languages sacrifice too much
 performance.   <sigh>

I can fix the bugs, but I need test cases!

Well this is a big improvement.  Wish I had symbol info inside VS .NET

I have a question... does printf show up in the Output log window (via
OutputDebugString) if you don't have a console open?

I have no idea. I just use regular printf's and redirect the output to a file. For a GUI app I have a printf that logs to a text file.

Right.  Oops!  Well that's the way I've always done it in C++ (Usually,
"void DebugPrintf(const char*,...);"), why should D be any different?

I thought Windows apps stubbed out the stdin/stdout/stderr handles;  I
wasn't aware you could redirect to a file.  Good to know.  Still it seems to
make sense to me that if you don't have a console, the output should go
somewhere useful (OutputDebugString) instead of to dev/nul.  Otherwise
newbies will printf a bunch of stuff and wonder why it doesn't show up
anywhere.

Maybe someone could make a redirector that dumps all of stdin to
OutputDebugString, and pipe the app to that.  Sounds easy enough but it
seems like there might be a process boundary issue.  Only one way to find
out!

I've thought of that solution myself, but I really think that it would be lacking in speed, and have a ton of integration issues, as there isn't a clean, automatic way at the moment to integrate python and C++. I'm also in the D games camp (if the d community ever grows large enough for SIGs). I plan, if the tools stabilize quickly enough, to write my next game demo (sample source and what have you) in D. While it's in C++ at the moment, I feel that porting what i have to D will be easy enough, once the tools fall into place, and will also result in a nice readability and code size improvement at the same time.
