Hello,
If a pretty-printed variable has children, in MI the to_string method is
ignored, and istead "{...}" is used.
To recreate:
Download bug.c, bug.py (They are the same as in bug 10615).
> gdb --int mi2 --nx bug
> -enable-pretty-printing
> python execfile('bug.py')
> b main
> r
> n
> -var-create m * m
^done,name="m",numchild="0",value="{...}",type="MainStruct",thread-id="1",has_more="1"
The value should have been "x=0".
To fix this, remove those two lines from varobj.c:
if (dynamic_varobj_has_child_method (var))
return xstrdup ("{...}");
They suggest that this behaviour was intentional. However, I would prefer if it
weren't so. I wrote a pretty-printer for a struct. The struct has many fields,
but only two are important. So I wrote a pretty-printer which keeps the children
of the struct, but uses to_string to display a string like "x=3,y=5", which
helps me see the important state of the struct in the GUI debugger without
having to open the struct in the tree view, so I have more space for watching
other variables.
Thanks,
Noam

I forgot: of course, you have to compile before anything:
> gcc -g -o bug bug.c

Yeah, this behavior in intentional.
I think you should raise this issue on the mailing list, there
are a couple threads touching on this.
bugzilla isn't really the best place to discuss it, as not everybody
is listening here. I'm closing the bug for this reason.
