--------------------------------------------------------------------
[~zabetak] had proposed to make the visualizer independent of the
VolcanoPlanner. As this would entail many chances to the Java part, I decided
to solve at the same time another problem that I had encountered in practice:
the size of the generated files is about Θ(nr), with n the number of nodes and
r the number of rule calls. Instead of storing the state at each rule
application, the new format just stores the changes at each step. So the size
of new format should be closer to Θ(n + r). The visualizer now works with the
VolcanoPlanner and the HepPlanner.
[~Chunwei Lei], [~zuozhiw], and [~zabetak] proposed to add a property to
activate generating the files for the visualizer, maybe depending on the log
level. How about adding a property to switch between printing the dot graph (as
it is currently done) and the visualizer? I would add a property for specifying
the output directory and the file name prefix, include a counter to the
filename (and maybe a timestamp), and print the name of the generated file in
the log. Any other proposals?
