Debugging

1. TDD: mix test <path>:<line> --trace
2. interactive shell: iex for running smaller blocks, also its commands i & h;
   iex -S mix phx.server then importing & calling functions, queries, requests, etc.
3. binding() |> IO.inspect(label: "#{__MODULE__}:#{__ENV__.line}") dbg/2.
4. Process.info(self(), :current_stacktrace) |> IO.inspect()
5. require IEx; IEx.pry()
6. from Ecto query to SQL string: Repo.to_sql(:all, query) |> elem(0) |> IO.puts()
7. Code Runner for running larger blocks
8. VSCode debugger's breakpoints
9. mix xref: mix xref graph --format dot then (with graphviz installed) dot -Tpdf xref_graph.dot -o xref_graph.pdf
