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”.
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.
Yeah, that’s what I ended up doing too after finishing a later section and confirming with the official project code.
Perhaps temporarily define @storage_dir in graph.ex and query.ex as “…”,
then redefine it later:
p.68 – Ch 2 > Building a Graph Store > Creating a Storage area
in GraphCommons.ex, where we define 4 directory output functions.
whatever works best
