Roughly, the pipeline is like this:

**The depend arrow.** Upon installing the `julials` server of `nvim-lspconfig` as instructed [here](https://github.com/neovim/nvim-lspconfig/blob/master/doc/configs.md#julials), one should have a folder

```julia-auto
~/.julia/environments/nvim-lspconfig

```

which looks like

```julia-auto
.
├── Manifest.toml
└── Project.toml

```

and inside `Manifest.toml`, one can find an entry `[[deps.JuliaFormatter]]`, which means that the language server depends on `JuliaFormatter` to do the LSP formatting.

So, to configure the formatting of this LSP, rather than controlling the behavior of some NeoVim plugin, one actually needs to configure the behavior of the `JuliaFormatter.jl` package.

* * *

**The config arrow.** In the docs of `JuliaFormatting.jl`, there is a section on how to use `.JuliaFormatter.toml` files to config the package. The project directory needs to have this dotfile and a `Project.toml` file (the latter is required!).

Note also that, once it sees a `Project.toml`, `JuliaFormatter` regards this as the root of its working directory, and stops searching for config files higher on the tree. See [this issue](https://github.com/mason-org/mason-lspconfig.nvim/issues/172), for example, and [this post](https://discourse.julialang.org/t/neovim-julia-lsp-formatting-on-subfolders-respecting-juliaformatter-toml/105900).
