FYI - have had a lot of success with using the Elixir plugin for Rubymine. It’s a little awkward to set the SDK, but after that, it works well. Under Languages in Preferences, click the arrow to expand Elixir and show the SDK options for Elixir and Erlang. Click the + under each and you’ll have to set the path by navigating to the appropriate directory where you have installed each. In my case, using ASDF, it’s under ~/.asdf/installs/elixir/<your version here>. Do this for Elixir under SDKs and Erlang under Internal Erlang SDKs. After that, you should see this version of Elixir in the SDK selection for the language (i.e. with the drop-down collapsed).
I haven’t gotten to try Vscode yet. I see a lot of folks using it, but I also use RM for my day job, so it’s more about familiarity than anything for me. The debugger works well for Elixir too.
