Generating a file describing the dependencies between ML files ?

Desired Behavior

Hello. I was wondering if it's possible to generate a file like ocamldep does. From such a file, one can generate a graph. It is quite useful for someone joining a project to get a graphical idea of how the files depend on each other. Thank you.

I think this may be a duplicate of ocaml/odoc#225

Hello, I have a similar need : given a whole dune project, have a command that gives you the dependencies between the .ml files that live in the project, and also between the .ml files of the project and .ml files used in external libraries (and the standard library).
Currently, the dune describe command only gives you dependencies at the granularity of dune libraries or executables. Moreover, the dependencies to external libraries that are given by dune describe are not very useful, because dune describe only refers to the UIDs of the external libraries, without giving any detail about which UID corresponds to which library.
It is true that I can manually find part of the fine-grained dependencies I need, by looking at the .ml.d files that are generated by dune (using ocamldep -modules), but not every source file has a corresponding .ml.d file, unfortunately.
My use case for the need of fine-grained dependencies between .ml files is a tool to analyze the complete source tree of a dune project.
Could the dune describe command be updated to dump the fine grained dependencies ?

PR#5412 hopefully provides a solution to the current issue.

@fblanqui : PR#5412 has been merged.
Do you think it solves the current bug report ?
EDIT: this is now merged in the main branch.

FYI, the following project produces that kind of graph you want: https://github.com/sim642/ocaml-depgraph/ based on dune's output.
I am thus closing the issue.
Please reopen it if you feel this is needed.
