Current behavior

A short description of the issue

Begin learning elixir recently, and I was setup the elixirls in neovim following this guide. I could get most of the lsp elixirls feature work, such as doc hover, snippet, autocompletion, and so on, but I found I just can’t get the autocompeletion work for local module in another file. I’ll describe my problem as follows:

I've got two files in same directory, person.exs and main.exs:

which can be seen from the pictures that the autocompeletion source for module Person failed in main.exs. However, when I move the statements to person.exs, I could get the expected autocompeletion:

At first I thought this would be a lack of implementation of something in elixirls, but when I switch to vscode, where I've installed the elixirls viscode extension, finding that the autocompeletion works as ecpected:

'No mixfile found in project. To use a subdirectory, set elixirLS.projectDir in your settings. Looked for mixfile at "/Users/huibosa/mix.exs"'

This is rather expected. You are running the language server in an ordinary directory. Person module is not compiled and hence the language server is unable to autosuggest. It works if the code is in the same file but without mix project it is not able to see the relationship between the files.

Try to run it in a mix project.

Thanks for your help, autocompletion works as expected after I run the module in a mix project
