I 'm a beginner of D and like it very much. But I cannot find debugger 
in the package. Isn't it convenient? 
If there is no debugger, how can I debug the code?

On linux, you can use gdb. On Windows, it will work with any codeview
compatible debugger. This includes windbg, vc's debugger, and the debuggers
that come with the Digital Mars C++ CD. -Walter

I cannot get MSVC6 to work correctly , i compile with -debug and -g , open
foo.exe in MSVC 6, Build->Start Debug-> Go , just executes the program, not
halting at the exception just running it out.

If i use Step Into() , it works ok , but I get no function names or values,
only mainCRTStartup + Offest in bytes.

Am i mis-using it ?  Has anyone gotten this to work with DMD .110 ?

CodeView version 2 right ?

The DM debugger works great.

I have no idea why VC6's debugger fails. If the same executable is working
with windbg.exe (on the DM C++ CD), then the debug info embedded in the
executable is correct.

Yea its correct and I've gotten it to work now thanks ( thanks also to AJill
: http://www.digitalmars.com/d/archives/digitalmars/D/1608.html )

On a side note, Microsoft(tm) now embeds typeinfo into the codeview
information ( tested with MSVC 6 and up ), which allow you to 'inspect'
classes and their methods by examing their type ( using DBGHELP's
SYMBOL_INFO.TypeInfo structure ).  In the article here :
http://msdn.microsoft.com/msdnmag/issues/02/03/hood/default.aspx it shows
how to do read this information;  It also mentions the old way of having
CodeView constants for each symbol type, is this the way DM does it ( there
is a dump program on that page that shows DM programs [ both dmc and dmd ]
dont use type info )  ?  If so where can I get a list of these constants (
this is for a debugger ) , or how else can i get the 'type'  of local
variables so I can display thier values.

Thanks!

Charlie

P.S.  The CodeView Typeinfo stuff is expandable , so you can setup your own
type for char [] and 'D' aware debuggers could read their values.  Getting
typeinfo into the CV info would be awesome!

It works for me.

One thing to note is that VC's debugger doesn't always break at exceptions. 
For example, it won't break if there's a exception handler in the 
application, which in D there always is (the handler that prints the 
exception on the console).

So for VC to break, you'll have to mark the exception as "break always" in 
the menu (only available while debugging): Debug -> Exceptions...
There, enter the exception number (as dumped in VCs output window), enter 
some human readable name and select as action "Stop always". Then click 
"Add".

Example,

void main( char[][] args )
{
  int *p = null;
  *p = 0;
}

Compile it with -g AND -debug. Run it from VC (F5, debug). In the console 
you'll see:

Error: Access Violation
Press any key to continue

And in the output pane:

Loaded 'ntdll.dll', no matching symbolic information found.
Loaded 'C:\WINDOWS\system32\kernel32.dll', no matching symbolic information 
found.
Loaded 'C:\WINDOWS\system32\user32.dll', no matching symbolic information 
found.
Loaded 'C:\WINDOWS\system32\gdi32.dll', no matching symbolic information 
found.
First-chance exception in fart.exe: 0xC0000005: Access Violation.
The thread 0x120 has exited with code 1 (0x1).
The program 'C:\UTIL\d\debug\fart.exe' has exited with code 1 (0x1).

But notice that VC did not break!

Now press F11(step into) and go to the menu Debug -> Exceptions. The 
exception 0xC0000005 exists so we don't add it but we select it. You'll see 
that the (default) action is "stop if not handled". Change this to "Stop 
always" and click "Change". Now continue running the program, F5. VC will 
break.

I hope this is clear.

It looks very useful to me. Good job!
