Disable hoverProvider in neovim

[jgirardet]

Hello,
Neovim 0.11.4 , ruff 0.14

I'm struggling configuring ruff in neovim like explained in the doc: https://docs.astral.sh/ruff/editors/setup/#neovim.
I tried starting fresh with the bare minimal : lazy , mason, lspconfig.

I tried an autocmd in lazy.config and using on_attach in plugin configuration but it doesn't the hover diagnostic keep showing :

This is my whole neovim config

-- Bootstrap lazy.nvim
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
  local lazyrepo = "https://github.com/folke/lazy.nvim.git"
  local out = vim.fn.system({ "git", "clone", "--filter=blob:none", "--branch=stable", lazyrepo, lazypath })
  if vim.v.shell_error ~= 0 then
    vim.api.nvim_echo({
      { "Failed to clone lazy.nvim:\n", "ErrorMsg" },
      { out, "WarningMsg" },
      { "\nPress any key to exit..." },
    }, true, {})
    vim.fn.getchar()
    os.exit(1)
  end
end
vim.opt.rtp:prepend(lazypath)


-- Setup lazy.nvim
require("lazy").setup({
  spec = {
	  
  {
    "mason-org/mason.nvim",
    opts = {}
  },
  {"neovim/nvim-lspconfig",
   config = function() 
	   -- Diagnostic configuration
	vim.lsp.config("ruff", {
	on_attach = function(client, buffer) 
	if client then 
	  client.server_capabilities.hoverProvider = false
	end
	
	end
	})
	vim.lsp.enable("ruff")

	vim.diagnostic.config {
	  severity_sort = true,
	  float = { border = 'rounded', source = 'if_many' },
	  virtual_text = {
	    current_line = true,
	    source = 'if_many',
	    spacing = 2,
	    format = function(diagnostic)
	      return diagnostic.message
	    end,
	  },
	  signs = {
	    text = {
	      [vim.diagnostic.severity.ERROR] = '󰅚',  -- Error icon
	      [vim.diagnostic.severity.WARN] = '󰀪',   -- Warning icon
	      [vim.diagnostic.severity.INFO] = '󰋽',   -- Info icon
	      [vim.diagnostic.severity.HINT] = '󰌶',   -- Hint icon
	    },
	  },
	}
   end

  },

    -- add your plugins here
  },

  config = function() 
	vim.api.nvim_create_autocmd("LspAttach", {
	  group = vim.api.nvim_create_augroup('lsp_attach_disable_ruff_hover', { clear = true }),
	  callback = function(args)
	    local client = vim.lsp.get_client_by_id(args.data.client_id)
	    if client == nil then
	      return
	    end
	    if client.name == 'ruff' then
	      -- Disable hover in favor of Pyright
	      client.server_capabilities.hoverProvider = false
	    end
	  end,
	  desc = 'LSP: Disable hover capability from Ruff',
	})

   end, 
  -- Configure any other settings here. See the documentation for more details.
  -- colorscheme that will be used when installing plugins.
  install = { colorscheme = { "habamax" } },
  -- automatically check for plugin updates
  checker = { enabled = true },
})

I don't use neovim myself, so apologies in advance if this isn't very helpful, but I asked ChatGPT about this, and it thought the diagnostics in your screenshot were a result of the vim.diagnostic.config setting rather than disabling hoverProvider. This is the snippet it suggested:

vim.diagnostic.config({
  float = false,
  virtual_text = false,
})

I tested this out with your config, and I think the second line was what actually helped to suppress the inline diagnostics from your screenshot.
