I recently started using Erlang\_LS with Emacs and Eglot. Whenever I save, my file is auto formatted (I’ve got `format-all-mode` setup) by Erlang\_LS through Eglot. However, I prefer to use `erlfmt` via `rebar3 fmt` and also the formatting with erlang\_ls is destructive sometimes, and my code won’t compile post formatting. Is there some configuration in `erlang_ls.config` to disable formatting so that it won’t format on save or on `M-x eglot-format`?

Now the ideal solution is to disable it through Emacs, but I need to go through `format-all-mode` and `eglot`’s source code as there isn’t documentation on not formatting/blacklisting a certain language. So I’m look for a temporary fix here till I have the time to write some Elisp.

Yes, there is.  
Add this to your `erlang_ls.config`:

```erlang
providers:
  disabled:
    - document-formatting

```

Check out this [example](https://github.com/williamthome/eel/blob/feat/new_strategy/erlang_ls.config).  
See also the `Erlang LS` [configuration docs](https://erlang-ls.github.io/configuration/).

Does anybody experience the same behaviour with eglot?
