Environment

• Elixir & Erlang versions (elixir --version): Erlang/OTP 23 [erts-11.1.7] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

Elixir 1.11.3 (compiled with Erlang/OTP 21)

• VSCode ElixirLS version: 0.7.0
• Operating System Version: darwin 20.3.0

Troubleshooting

• Restart your editor (which will restart ElixirLS) sometimes fixes issues
• Stop your editor, remove the entire .elixir_ls directory, then restart your editor
  • NOTE: This will cause you to have to re-run the dialyzer build for your project

You can reproduce this by deleting the .elixir_ls directory, and then saving a file to trigger the LS to start recompiling, then run the formatter. You observe that it is not respecting the formatter configuration because it is adding parens to Ecto functions/macros that shouldn't have parens.

The screen recording I added above using VSCode, but I have also reproduced it with Neovim builtin language client.

I personally have never run into this race condition, but my coworkers constantly are pushing up code that is clearly formatted incorrectly, and I traced it down to this issue.

Thanks!
