digitalmars.D - Where to find a debugger?

reply Chris <central_p hotmail.com> writes:
This question may be asked a thousand times but I'm completely stuck.
I've checked all the recommended debuggers but none seems to work on 
Windows?

Where can I find an earlier version of WinDbg?

Are there any alternatives to debug D programs? How do you debug?


Thank you,
  Chris

I'd recommend OpenWatcom debugger.

Thank you,

but how do I use OpenWatcom debugger with D? I can't make it to work as 
  I expect - set breakpoints in the D source file, etc. It just shows me 
a disassembly.

You can google
intitle:index.of "windbg.exe"

in this thread 
http://www.digitalmars.com/d/archives/digitalmars/D/30966.html
I said:

<quote myself>
I had success seeing variables using the windbg here:
http://www.cs.nmt.edu/~cs221/jbpub/Detmer/Software/

(I downloaded it using the DownThemAll firefox extension!)

BUT, it showed the hexadecimal values of the variables!
I was able to make it show the decimal values by going
options->debugger->Radix and choose the "decimal" radio button.

Thank you, I've managed to make it work for now.

Any other tips than John's tips further down in the thread?

There are two debuggers on the DMC CD, one that comes with the IDE ( much
better than windbg ) and an old windbg.

The wiki has a few debuggers mentioned:
http://www.prowiki.org/wiki4d/wiki.cgi?DebugEnvironments

As far as I know, the VS2005 debugger can't be used, but I may be wrong.

Thank you for you tips! I finally got WinDbg working. OpenWatcom seems 
as if it is working too.

BTW. How do you watch strings?

I have this:

     debug
     {
         char [] h_Name = student.Name;
         int h_Age = student.Age;
     }

.Name and .Age are properties. For .Age I get a number but I also get a 
scary number for the string .Name? Can't I view the string value somehow?

And also this doesn't work for properties.

debug
{
   int *h_ounces = &hamburger.ounces;
   float *h_cost = &hamburger.cost;
}

Regards,
        Chris

Its not real pretty, but this should work if they're just fields:

# debug {
#   int   * h_ounces ;
#   float * h_cost   ;
#
#   with (hamburger) {
#     h_ounces = &ounces ;
#     h_cost   = &cost   ;
#   }
# }

If, on the other hand, the properties are gettor methods, then I don't think
you can 
'address' them at all - except maybe with an 'address gettor'.

# class Hamburger {
#   // ... blah
#   int* ouncesPtr () { return &p_ounces; }
# }
# // ... blah
# with (hamburger)
#   int * h_ounces = ouncesPtr ;

Thank you, Chris


I cannot say I understand D properties very well. I've  just compiled my
"Hi" program to test compiling and debugging:


main.d

import std.stdio;
import student;

void main()
{
     int i;
     i = 1;
     i++;
     printf("Hi! The number is: %d",i);

     Student student = new Student("John Smith", 30);
     writefln("\nFile is:  %s", __FILE__);
     writefln("Line is:  %s", __LINE__);

     // Debug variables needed to debug with WinDbg
     debug
     {
         char [] h_Name = student.Name;
         int h_Age = student.Age;
     }
     writefln("\nName is: %s\nAge is:  %d", student.Name, student.Age);

     printf("\n\nNow press a key to continue!");
     getch();
}


student.d

class Student
{
     private
     {
         char [] name;
         int   age;
     }

     char [] Name() { return name; }
     void Name(char [] value) { name = value; }
     int Age() { return age; }
     void Age(int value) { age = value; }


     Student next;

     this(char [] name, int age)
     {
         this.name = name;
         this.age = age;
     }
}
