Exploring Graphs with Elixir: Missing module attribute? (57)
Exploring Graphs with Elixir by @tonyhammond
When defining the GraphCommons.Graph module, I noticed a missing module definition for @storage_dir
To align with the expected output when testing new/3 (p.61), I defined it as “…”
From what I think, this will later be defined from “system-defined inputs for project location and Mix environment”.
Marked As Solved

For now I have added the following to both graph.ex and query.ex
@storage_dir GraphCommons.storage_dir()
It’s a hack but works for now.
