If you have elixir in your path, you should just be able to install the extension in vscode and it should just work.

Other data that might help debug,

1. is there any messages in the output tab of the builtin terminal?
2. is there there anything is the .elixir_ls in your project directory (same level as your project mix.exs)

I’m having the same issue. Actually Intellisense works for elixir methods, but not for my own classes. Is it suppose to work this way?

There are neither methods, nor classes in elixir, so I assume you are meaning functions and modules.

Can you tell us how you manage your erlang/elixir installation and how you start vs code?

If you use anything other than your systems installation of elixir and starting vs code from the GUI, you are doing it wrong.

Try starting it from the terminal you used to verify that the correct version of erlang and elixir are available.

Yes sorry, I meant Modules and Functions.

I’m running windows, installed elixir through the installer but override OTP to use version 21.

Output of elixir -v:

Erlang/OTP 21 [erts-10.1] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

Elixir 1.8.0-dev (929e58c) (compiled with Erlang/OTP 21)

I’m using the plugins vscode-elixir and ElixirLS. Autocomplete/intellisense works fine for Elixir own modules, but vscode can’t even recognize the name of my modules. When I start typing there’s no suggestion for them nad neither for the module functions.

So, disabling ElixirLS makes the default vscode intellisense work (it searches for used words in the document and I can select them), but then I lose the autocomplete for the Elixir modules. Disabling only vscode-elixir seems to make no difference on the mentioned problem - I have autocomplete on Elixir modules but intellisense on the document for my own code doesn’t work.

I can confirm same behavior on MacOS Mojave. I should probably create an issue on the ElixirLS plugin repo.

Thanks for your help!
