I'm in the process of trying to track down an error in how my
object graph is being updated, and would like to be able to
visualize the current state of the graph at all times. The
debugger in XCode allows me to either a) view the current state of
the variables of my structs using the default format or b) create
a custom formatter that only displays text. I would rather use
GraphViz to display a graphical rendering of what my object graph
is like as I'm stepping thru my code, but this requires knowledge
of the current state of the machine at each step.
I've had the same issue. It may be resolved by writing a function
that dump the graph in a .dot file, and then open this file with
GraphViz.
This is actually what I'm doing right now, except that instead of
dumping the entire graph, I dump just the deltas, and then
postprocess, detecting the deltas and building up the graph as I go.
Don't forget that you may run (with the gdb prompt of Xcode's
debugger) any function you want, like the classical "print-object
my_objc_var" or "p (void)CFSHow(my_corefoundation_var)". Here, this
will be a :
p (void)DumpMyGraph("/tmp/dump.dot", my_graph_root)
You just need to write the function DumpMyGraph, and check that it
is not optimized away.
I hadn't thought about that! I'll have to spend some time playing
with it... Thank you!
Thanks,
Cem Karan
