Exploring Graphs with Elixir

Building a Dynamic Process Graph

Now that we’ve defined some of the machinery for creating and maintaining a supervision tree, we can turn to the process graph itself.

Let’s create a new module:

defmodule GraphCompute.ProcessGraph do

  # ...

end

We should now have a module library tree that looks like this:

.
├── README.md
├── lib
│   ├── graph_compute
│   │   ├── application.ex
│   │   ├── graph.ex
│   │   ├── process_graph.ex
│   │   ├── process.ex
│   │   └── state.ex
│   └── graph_compute.ex

We now want to add a simple function—let’s call it graph_up/1—that will map any %Graph{} struct to a new %Graph{} struct, where nodes are replaced by supervised processes and the node terms are stored away in the supervised node’s ...
