Root directory not found, Neovim and Lspconfig

[pauladam94]

Here is my config for the LSP in neovim in init.lua.

  {
    "neovim/nvim-lspconfig",
    dependencies = {
      "kevinhwang91/nvim-ufo",
      { "j-hui/fidget.nvim", opts = {} },
      { "folke/neodev.nvim", opts = {} },
    },
    -- This was an unsuccessful try
    -- opts = {
    --  servers = {
    --    tinymist = {
    --      settings = {
    --        rootPath = "~/PaulJR/",
    --      },
    --    },
    --  },
    --},
      local capabilities = vim.lsp.protocol.make_client_capabilities()
      capabilities = vim.tbl_deep_extend("force", capabilities, require("cmp_nvim_lsp").default_capabilities())

      local lsp_capabilities = require("cmp_nvim_lsp").default_capabilities()

      -- TINYMIST
      require("lspconfig")["tinymist"].setup {
        capabilities = lsp_capabilities,
        settings = {
          tinymist = {
          -- another unsucessfull try
           --  rootPath = "~/PaulJR/",
            settings = {
              rootPath = "~/PaulJR/",
            },
          },
        },
      }
}

In the tinymist docs, for the root path it is indicated to put - for getting the parent directory. Is it the string "-" right ? Just to be sure because I also have tried that but it didn't work.

Here is the result of LspInfo :

 0 client(s) attached to this buffer:

• I am using lazy for getting package in neovim
• Just to explain why I don't use Mason, I am using NixOS and mason does not work it (as far as know).
• I have installed through the nix package manager which is what i have done for other lsp.
• I have everytime restarted neovim
• I have other lsp setup that way and they work (cland, rust-analyzer).
• tynymist is well installed on my computer

Maybe I am doing something obviously wrong, that's why I post this issue. Thank in advance.

I actually managed to make it work. Actually in neovim. Instead of changing the tynimyst parameter rootPath, it is the lspconfig parameter root_dir that should be changed.

This fix my issue :

      require("lspconfig")["tinymist"].setup {
        capabilities = lsp_capabilities,
        root_dir = function(filename, bufnr)
          return "/home/pauladam/PaulJR/" -- this is fixed, but other function can take the parent directory in neovim
        end,
    }

Once you know that, any thing can be given to root_dir parameter.

Sorry I'm late, I was busy when I first checked your issue. I think of it is a bit unfortunate that there are some unintentional similar keys that are confusing people. But root_dir is a neovim specific configuration. But we could document it to avoid future pitfall.

Just to be sure, it this way that should work to put settings for the tinymist ?

  {
    "neovim/nvim-lspconfig",
    dependencies = {
      "kevinhwang91/nvim-ufo",
      { "j-hui/fidget.nvim", opts = {} },
      { "folke/neodev.nvim", opts = {} },
    },
      local capabilities = vim.lsp.protocol.make_client_capabilities()
      capabilities = vim.tbl_deep_extend("force", capabilities, require("cmp_nvim_lsp").default_capabilities())

      local lsp_capabilities = require("cmp_nvim_lsp").default_capabilities()

      require("lspconfig")["tinymist"].setup {
        capabilities = lsp_capabilities,
        root_dir = function(filename, bufnr)
              return "the right root_dire depending on filename..."
          end
        settings = {
          tinymist = {
            settings = {
              formatterMode = "typstfmt",
            },
          },
        },
      }
    }

I don't see obvious errors in your posted code.

[FahimAnayet]

root_dir = function(filename, bufnr)
           return vim.fn.getcwd()
           end,

This is much more dynamic. But this may change the workspace every time :(
