Hello everyone,

Neovim 0.11 seems to have introduced some [changes](https://github.com/neovim/nvim-lspconfig?tab=readme-ov-file#configuration) in the way lsp is configured, and it seems the julials install from [Mason](https://github.com/mason-org/mason.nvim) does not work out of the box at the moment (lsp quits returning 1 instead of 0, error log looks like nonsense).

I am currently using the following config, combining the new lsp setting with the instructions from [here](https://www.juliabloggers.com/setting-up-julia-lsp-for-neovim/) :

```lua
vim.lsp.config['julials'] = {
    cmd = { '' },
    filetypes = { 'julia' },
    root_markers = { 'Project.toml', 'Manifest.toml' },

    settings = {
        require'lspconfig'.julials.setup{
            on_new_config = function(new_config, _)
                local julia = vim.fn.expand("~/.julia/environments/lsp/")
                if require'lspconfig'.util.path.is_file(julia) then
                    new_config.cmd[1] = julia
                end
            end
        }
    }
}

```

, which seems to work, even though I barely understand how.  
The only problem so far with this setup, is that it does not seem to use the local Project.toml, and I don’t get suggestions for packages defined in there.  
Would there be a straightforward way to improve it?

Any advice would be very welcome.

Update: The following does the job;

```lua
vim.lsp.config('julials', {
    cmd = {
        "julia",
        "--project=".."~/.julia/environments/lsp/",
        "--startup-file=no",
        "--history-file=no",
        "-e", [[
            using Pkg
            Pkg.instantiate()
            using LanguageServer
        depot_path = get(ENV, "JULIA_DEPOT_PATH", "")
        project_path = let
            dirname(something(
                ## 1. Finds an explicitly set project (JULIA_PROJECT)
                Base.load_path_expand((
                    p = get(ENV, "JULIA_PROJECT", nothing);
                        p === nothing ? nothing : isempty(p) ? nothing : p
                    )),
                        ## 2. Look for a Project.toml file in the current working directory,
                        ## or parent directories, with $HOME as an upper boundary
                        Base.current_project(),
                        ## 3. First entry in the load path
                        get(Base.load_path(), 1, nothing),
                        ## 4. Fallback to default global environment,
                        ## this is more or less unreachable
                    Base.load_path_expand("@v#.#"),
                ))
            end
                    @info "Running language server" VERSION pwd() project_path depot_path
                    server = LanguageServer.LanguageServerInstance(stdin, stdout, project_path, depot_path)
        server.runlinter = true
            run(server)
        ]]
    },
    filetypes = { 'julia' },
    root_markers = { "Project.toml", "JuliaProject.toml" },
    settings = {}
})

```

should this be updated in [Vim and Neovim · julia-vscode/LanguageServer.jl Wiki · GitHub](https://github.com/julia-vscode/LanguageServer.jl/wiki/Vim-and-Neovim) ?

Might be a good idea to add some of the links in my posts above about the breaking changes in the newest release. Shall I do a PR?

Necroing because this thread comes up via Google.

I have updated the wiki with instructions for the new Neovim API: [Vim and Neovim · julia-vscode/LanguageServer.jl Wiki · GitHub](https://github.com/julia-vscode/LanguageServer.jl/wiki/Vim-and-Neovim#vimlspconfig---new-api-in-neovim-011)

You can definitely handroll your own config as shown above and power users will definitely want to do that, but I think for the average user the easiest way is to still rely on the default configs provided in [GitHub - neovim/nvim-lspconfig: Quickstart configs for Nvim LSP](https://github.com/neovim/nvim-lspconfig), so the instructions I wrote are based on that.

TLDR if you don’t want to click on the link:

1. Add the [GitHub - neovim/nvim-lspconfig: Quickstart configs for Nvim LSP](https://github.com/neovim/nvim-lspconfig) plugin.
2. `julia --project=~/.julia/environments/nvim-lspconfig -e 'using Pkg; Pkg.add("LanguageServer"); Pkg.add("SymbolServer"); Pkg.add("StaticLint")'`
3. add `vim.lsp.enable('julials')` to `init.lua` or similar

@penelopeysm, Thanks a lot for taking care of this!

Does this approach support using a custom sysimage? [Neovim Native LSP with julials using PackageCompiled LanguageServer](https://discourse.julialang.org/t/neovim-native-lsp-with-julials-using-packagecompiled-languageserver/57659)

Otherwise, I’m afraid the Julia LSP is notorious for its slow startup times.

My final config after `using PackageCompiler; create_sysimage([:LanguageServer,:SymbolServer, :StaticLint], sysimage_path="./julials.so", precompile_statements_file="./tracecompilelsp.jl")`

```lua
-- ~/.config/nvim/after/lsp/julials.lua
local env_path = vim.fn.expand '~/.julia/environments/nvim-lspconfig/'
local sysimage_path = env_path .. 'julials.so'

return {
  cmd = {
    'julia',
    '--project=' .. env_path,
    '--startup-file=no',
    '--history-file=no',
    '--sysimage=' .. sysimage_path,
    '--sysimage-native-code=yes',
    '-e',
    [[
      using Pkg;
      Pkg.instantiate()
      using LanguageServer, SymbolServer, StaticLint
      depot_path = get(ENV, "JULIA_DEPOT_PATH", "")
      project_path = dirname(something(Base.current_project(pwd()), Base.load_path_expand(LOAD_PATH[2])))
      @info "Running mark language server" env=Base.load_path()[1] pwd() project_path depot_path
      server = LanguageServer.LanguageServerInstance(stdin, stdout, project_path, depot_path);
      server.runlinter = true;
      run(server);
    ]],
  },
}

```

```julia-auto
