Re: [Boost-users] Visual Studio 2005 ptr_list visualizer?

I have written visualizers for the other pointer containers, but realize
that I had forgotten about ptr_list. I previously posted the visualizer code
for ptr_vector, ptr_map, ptr_multimap, ptr_set, ptr_multiset, and also
array. If you don't have it I can easily post it again.

I took a quick stab at ptr_list, but I think I may have run into a
limitation (or bug) in the visualizer. It's not letting me cast the final
expression to the templated parameter. I tried it with a direct cast and
that worked, but it seems to lose the template information in the resulting
expression.

The problem is in the expression ($T1*)$e._Myval. It seems that $T1 (the
template parameter) is not valid at this point. If, for example the list is
defined as ptr_list<int>, then the expression (int*)$e._Myval will work, but
obviously we can't hard code that here. Any one have any ideas here?

First attempt posted here (this does not include the iterators yet):

boost::ptr_list<*>{

	(
		#list
		(
			head : ($c.c_._Myhead->_Next),
			size : $c.c_._Mysize, 
			next : _Next
		) : ($T1*)$e._Myval
	)
		          
	preview
	(
		#(
			"[", 
			$e._Mysize, 
			"](", 
		  
			#list
			(
				head : $c.c_._Myhead->_Next,
				size : $c.c_._Mysize, 
				next : _Next
			) : ($T1*)$e._Myval,
		 
			")"
		)
	)			      
}
