package dune-deps

dune-deps

Show the internal dependencies in your OCaml/Reason/Dune project.

Input: the root folder of your project

Output: a graph in the dot format

Example:

$ dune-deps | tred > deps.dot
$ dot -Tpng deps.dot -o deps.png

This is the graph we obtain for the source code of opam:

Installation

From opam:

$ opam update
$ opam install dune-deps

From the git repo:

$ make
$ make test
$ make install

Rendering the graph

For producing a 2D image of the graph, we rely on the dot command from Graphviz.

Additionally, it is often desirable to remove excessive edges to make the graph more readable. We consider "excessive" an edge that can be removed without changing the reachability from a node to another. This transformation is called transitive reduction and is performed by tred, normally installed as part of the Graphviz suite.
