Elixir formatter in neovim (using coc.nvim) sometimes adds parenthesis around macros

I’d guess this is related to this elixir-ls issue: Formatter doesn't respect formatter.exs while your code is still compiling · Issue #526 · elixir-lsp/elixir-ls · GitHub

If you wait for the underlying compilation to finish, the formatter options are respected again, which makes it seem random.

Ah!

Thank you

Sorry to revive this, I’m experiencing this all the time in NeoVim (LazyVim). I’ve already updated all plugins to their latest versions, and using Eliixir 1.15. It doesn’t add parenthesis in VS Code. Not sure what else to try..

Not sure if that helps but you could just specify these exceptions in your own .formatter.exs in the root of your project. Here’s an example from one of mine:

[
  import_deps: [:ecto, :phoenix],
  inputs: ["*.{ex,exs}", "priv/*/seeds.exs", "{config,lib,test}/**/*.{ex,exs}"],
  locals_without_parens: [from: 2],
  line_length: 100,
  subdirectories: ["priv/*/migrations"]
]

In this case, I don’t want Ecto.Query.from be given parentheses.

Oh, here’s a more detailed example:

[
  inputs: ["mix.exs", ".formatter.exs", "{config,lib,test,priv}/**/*.{ex,exs}"],
  locals_without_parens: [
    # Plug
    plug: 1,
    plug: 2,

    # Phoenix
    pipe_through: 1,
    render: :*,
    action_fallback: 1,
    get: :*,
    post: :*,
    put: :*,
    delete: :*,

    # Ecto
    add: 2,
    add: 3,
    field: 2,
    belongs_to: 2,
    from: 2,
    embeds_many: 2
  ]
]

Thanks - I’ve tried that and even [:*], and it doesn’t seem to have any effect..

Well admittedly I don’t use coc.nvim so not sure I can help further. I use other NeoVim plugins.

I don’t think mine uses coc either - here’s the list of the ones in use, I believe: LazyVim/lua/lazyvim/plugins/extras/lang/elixir.lua at 68ff818a5bb7549f90b05e412b76fe448f605ffb · LazyVim/LazyVim · GitHub (also nvim-lint is enabled by default, while none-ls is not).

So it does seem to use elixir_ls under the hood, but for some reason it only behaves correctly in VS Code wrt formatting (other functionality like linting works well).

Even though I use NeoVim for a year or so now, I am very slowly learning it (not enough time or energy to become a pro there at the moment). So not sure I can help – maybe try disabling credo?
