The contents of a graphviz-readable file should be dumped to the
console (or a
log file?). If you save lilypond's output (from "digraph G" to the
end) to a
file named test.dot and run
$ dot -Tps test.dot -o test.ps
(or using graphviz somehow from the gui -- I don't know how, sorry)
then you
should get a .ps file that shows internal interactions between grobs.
Since this output is mainly used for internal debugging, I'm not
exactly sure
what counts as a regression. I suppose as long as the output works
with
graphviz to correctly render a graph, it counts as working. I've
just checked
that it works for me with graphviz version 2.12; if it doesn't work
with your
version, I'll add a comment to that effect in the file.
Joe-
Thanks for the explanation. I did as you suggested (running from the
terminal) and copied the output for the regression example. This is
what was generated:
digraph G {
rankdir="LR"
node [shape=rectangle]
}
I saved the file, opened it with Graphviz, and (!) a rectangle was
drawn. I'll assume it is working.
Regards,
Stan
