Opus.Graph

A complementary package for Opus which visualises pipelines using Graphviz.

Installation

The package can be installed by adding opus_graph to your list of dependencies in mix.exs:

def deps do
  [{:opus_graph, "~> 0.1"}]
end

Opus.Graph.generate(:your_app)
# => {:ok, "Graph file has been written to your_app_opus_graph.png"}

This feature uses graphviz, so make sure to have it installed. To install it:

# MacOS

brew install graphviz

# Debian / Ubuntu

apt-get install graphviz

Opus.Graph is in fact a pipeline and its visualisation is:

graph-png

You can customise the visualisation:

Opus.Graph.generate(:your_app, %{filetype: :svg})
# => {:ok, "Graph file has been written to your_app_opus_graph.svg"}
