Rebar Deps Graph

Generate a dependency graph with Rebar.

Install

In your rebar.config, add the following lines :

{deps, [{rebar_deps_graph, ".*",
         {git, "git://github.com/emedia-project/rebar_deps_graph"}}]}.

{plugins, [deps_graph_plugin] }.

That's all ;)

This plugin has been tested with rebar 2.3.0.

Usage

First, get the dependencies :

rebar get-deps

Then, use the grapg-deps command to generate the graph :

rebar graph-deps [graph=<file>]

Attribute graph allow you to specify an output file. If not present, the result will be send on the standard output. You can also use the deps_graph_file configuration in your rebar.config file. If both are present, the graph option will be use.

The output is a Graphviz file.

Example

The following image show the dependency graph of the emedia project.

An edge between a named node and a point indicate that the plugin was unable to retrieve the dependency for the given node. In this example, the dependencies for file monitor, cowling and ranch are unknown.

Here is another example for the Riak project.
