Go-to-definition & hover lost when using dynamic module calls via Application.get_env/3 #489
Description
I’ve noticed that ElixirLS navigation and hover only work when I call modules directly, but break as soon as I switch to a dynamic lookup via Application.get_env/3.
Direct calls (works)
defmodule TaskProcessor.Events do alias TaskProcessor.Segments alias TaskProcessor.Events.Queue.Oban, as: EventsQueue alias TaskProcessor.Events.Persistance.Ecto, as: Repo def enqueue_create_event(event_id) when is_integer(event_id) and event_id > 0 do EventsQueue.enqueue_create_event(event_id) end def enqueue_create_event(bad_event_id), do: {:error, {:invalid_event_id, bad_event_id}} def process_event(%{event_id: id, isCreated: true}) do case Repo.fetch_with_segments(id) do :not_found -> {:error, :not_found} {:ok, %{date: date, segments: segs}} -> Segments.schedule_segments(segs, id, date) end end end - Cmd+Click on EventsQueue.enqueue_create_event/1 or Repo.fetch_with_segments/1 jumps to the implementation.
- Hover shows the function signature.
Dynamic calls (Not working, or am i not doing right ?)
defmodule TaskProcessor.Events.Impl do @behaviour TaskProcessor.Events.Behavior alias TaskProcessor.Segments @impl true @spec enqueue_create_event(any()) :: {:ok, Oban.Job.t()} | {:error, any()} def enqueue_create_event(event_id) when is_integer(event_id) and event_id > 0 do queue_impl().enqueue_create_event(event_id) end def enqueue_create_event(bad_event_id), do: {:error, {:invalid_event_id, bad_event_id}} @impl true def process_event(%{event_id: id, isCreated: true}) do case repo_impl().fetch_with_segments(id) do :not_found -> {:error, :not_found} {:ok, %{date: date, segments: segs}} -> Segments.schedule_segments(segs, id, date) end end defp queue_impl do Application.get_env(:task_processor, :events_queue, TaskProcessor.Events.Queue.Oban) end defp repo_impl do Application.get_env(:task_processor, :events_repo, TaskProcessor.Events.Persistance.Ecto) end end - Cmd+Click on queue_impl().enqueue_create_event/1 or repo_impl().fetch_with_segments/1 does nothing.
- Hover shows nothing
Environment
- ElixirLS version: 0.28.0 - Elixir version: 1.18.4 - Erlang/OTP version: 28 - Macbook M1 Is there any way to configure ElixirLS (or leverage Dialyzer/Elixir compiler hints) so that go-to-definition and hover info work for modules resolved at runtime via Application.get_env/3? I need this functionality so that I can dynamically inject mocks during tests using the Mox library.
Thank you!
