Can't hover on well known functions

[andrepaes]

Hey, i'm trying to hover on functions that i'm pretty sure that has docs and the lsp is saying that it doesn't exists. For some functions it works but for others don't, so i think it's not related with my nvim configs.

Some functions on Map module works but others don't, the same occurs for Enum module and for custom functions/types.

Thanks in advance,
André Luiz

Thanks for the report

I think the first thing is because we might not being indexing types yet.

The third screenshot seems to be odd.

would you mind copy pasting that code so i can test it?

also as a quick test, can you see what happens if you format that last snippet like this and hten save and check

expected_payload = Map.take(
  body,
  Map.keys(@bet_payload_keys)
)

if that is the case, it might be related to #184

It seems to not be related with the format.

defmodule Parsers.Bet do
  @bet_payload_keys %{
    user: &is_binary/1,
    transaction_uuid: &is_binary/1,
    round: &is_binary/1,
    request_uuid: &is_binary/1,
    game_code: &is_binary/1,
    currency: &is_binary/1,
    bet: &is_binary/1,
    amount: &is_integer/1
  }

  @spec parse(map()) :: {:ok, map()} | {:error, :wrong_types}
  def parse(body) do
    expected_payload =
      Map.take(
        body,
        Map.keys(@bet_payload_keys)
      )

    valid_types? =
      Enum.all?(expected_payload, fn {key, value} ->
        validator = @bet_payload_keys[key]

        validator.(value)
      end)

    if valid_types? do
      {:ok, expected_payload}
    else
      {:error, :wrong_types}
    end
  end
end

I was able to replicate, thanks for the report!

actually, this might be because you're erlang wasn't built with docs.

the reason why that is apparent for the Map.keys/1 function is because it is inlined by the compiler (there is a bug fix for that on Elixir main), so it would show the erlang docs instead

if you install erlang with asdf or rtx, you can do KERL_BUILD_DOCS=1 asdf install erlang <version> and then it will work
