Inconsistent formatting when opening multiple projects about vscode-elixir-ls HOT 4 CLOSED

In the case where I have multiple projects (e.g. I usually open both the frontend and backend) and the elixir project is not first (backend first then frontend), the formatter doesn't seem to respect the .formatter.exs file.

Can you explain exactly how you're opening the multiple projects? Is the elixir project not at the root of the workspace? Are there multiple elixir projects?

After moving the project in the 2nd+ position it adds the parenthesis:

What exactly do you mean by moving the project?

I apologize if these are basic questions, but I don't use VSCode as my primary editor.

@axelson sure! No worries my bad for not explaining those properly.

Imagine this folder structure:

Desktop
 | frontend
 | backend

if I only open the backend folder, everything is working properly, formatter works fine as expected.
If I then do File > Add folder to Workspace and I select the frontend folder I end up in this situation:

so my editor has two open folders, backend first and then frontend (look at the sidebar). Saving and/or manually formatting the file works fine.
If I switch the backend and frontend positions like this:

you can see that now the formatter added the parenthesis to the code, like it's not picking the formatter configuration from the project.

Thanks for the detailed instructions! Okay, this seems like a subset of #58, I'll leave it open for now since it's possible this could be fixed before adding general support for multiple project folders. But the workaround is to open a new editor instance for each project. PR's are of course welcome, although they may involve significant work to https://github.com/elixir-lsp/elixir-ls/ to handle multiple project directories simultaneously (but if we're scoping that to just formatting it is probably significantly easier).
