being able to output dependencies

[UnixJunkie]

Hello,

I about I add the possibility to output the dependency
graph of all installed packages in a way that
can be used by external tools such as dot from graphviz
so that people can visualize the dependency graph?

Regards,
F.

That sounds like an interesting and potentially useful project. It can
fit into the odb project if you like, but I'm hesitant to include it
inside the odb.ml file. As a separate program, no problem. Also, only
doing this for installed packages doesn't need odb, only findlib, but it
may be a good destination. Try starting by drawing the dep graph of all
packages in a repo.

OK, the first step will be to have a real graph in the Dep module of odb.ml.
I may do this after my "user re-definable actions" proposal.
Then, we may become able to update /re-install packages more efficiently
or to uninstall some properly.

Should I try to display the dependency graph from odb or
just output the graph to a user-given filename
and output the command to convert it to a png file?
Then the user will use whatever png viewer he likes to see it.

I think the latter is better as it does not imply any dependency
to the graphviz toolsuite neither any image viewer.
