How do I unregister null-ls as a formatter for certain filetypes to avoid prompts?

[mystilleef]

When multiple formatters are available, NeoVim prompts you to choose one. This is annoying if automatic formatting is enabled. How do I unregister null-ls as a formatter for certain filetypes to prevent the prompts?

I had my formatter.with filetypes configured wrong. Proper configuration prevents the prompt.

I do have that issue. here is the video

I like the null-ls formatter more than html-server's. But when I disable it says some error

[jose-elias-alvarez]

Are you calling setup more than once? The error you're getting indicates that something is wrong with your HTML language server configuration (just adding on_attach shouldn't make a difference).

I am doing something with lsp install though. here

local function setup_servers()
   lspinstall.setup()
   local servers = lspinstall.installed_servers()
   for _, lang in pairs(servers) do
      if lang ~= "lua" or "html" then
         lspconfig[lang].setup {
            on_attach = on_attach,
            capabilities = capabilities,
            -- root_dir = vim.loop.cwd,
         }
      elseif lang == "lua" then
         lspconfig[lang].setup {
            on_attach = on_attach,
            capabilities = capabilities,
            settings = {
               Lua = {
                  diagnostics = {
                     globals = { "vim" },
                  },
                  workspace = {
                     library = {
                        [vim.fn.expand "$VIMRUNTIME/lua"] = true,
                        [vim.fn.expand "$VIMRUNTIME/lua/vim/lsp"] = true,
                     },
                     maxPreload = 100000,
                     preloadFileSize = 10000,
                  },
                  telemetry = {
                     enable = false,
                  },
               },
            },
         }
      end
   end
end

setup_servers()

I can't say for sure, but I think it's because you're using lspinstall. Since you seem to be reusing the same on_attach callback, I'd suggest modifying it:

on_attach = function(client)
    if client.name == "html" then
        client.resolved_capabilities.document_formatting = false
    end
end

At this point, this isn't really a null-ls issue, though and I don't use lspinstall so this is all I can suggest.

thank you for your time.

Thank you 😊. Have a nice day 👍

If you don't want to use the HTML language server for formatting, you can disable its formatting capabilities in its on_attach callback: require("lspconfig").html.setup({ on_attach = function(client) client.resolved_capabilities.document_formatting = false end, }) This will make Neovim default to null-ls formatting. — You are receiving this because you commented.
