setup_handlers -> vim.lsp.config

[mainendra]

Please help me convert setup_handlers to use vim.lsp.config instead

        local lspconfig = require('lspconfig')
        mason_lspconfig.setup_handlers({
            function(server_name)
                lspconfig[server_name].setup {
                    on_attach = on_attach
                }
            end,
            ['ts_ls'] = function()
                lspconfig['ts_ls'].setup {
                    on_attach = on_attach,
                    root_dir = lspconfig.util.root_pattern("package.json"),
                    single_file_support = false,
                }
            end,
            ['denols'] = function()
                lspconfig['denols'].setup {
                    on_attach = on_attach,
                    root_dir = lspconfig.util.root_pattern("deno.json", "deno.jsonc"),
                }
            end,
            ['lua_ls'] = function()
                lspconfig.lua_ls.setup {
                    on_attach = on_attach,
                    settings = {
                        Lua = {
                            diagnostics = {
                                globals = { 'vim' }
                            }
                        }
                    }
                }
            end,
        })

specifically root_dir attribute is not working

When I use

        vim.lsp.config('ts_ls', {
            on_attach = on_attach,
            root_dir = lspconfig.util.root_pattern('package.json'),
            single_file_support = false,
        })

then it's not attaching ts_ls server (same for denols)

This is technically not related to Mason as these things are in core Neovim. With vim.lsp.config you specify the "root directory" via either root_markers or root_dir (see :h vim.lsp.Config). single_file_support = false is now workspace_required = true.

 vim.lsp.config('ts_ls', {
     on_attach = on_attach,
-    root_dir = lspconfig.util.root_pattern('package.json'),
-    single_file_support = false,
+    root_markers = { 'package.json' },
+    workspace_required = true,
 })

Thanks @williamboman. Actually the issue is I don't want to attached both servers at the same time. So, if root_dir contains package.json then use ts_ls server and if it contains deno.json then use denols. I was using setup_handlers to handle that. It would be helpful you can help me fix that. Yeah, it's not directly related to Mason but still. Thanks.

@mainendra

Didn't see this discussion before posting mine but figured out how to do to do this with vim.lsp.config.
Now have to declare it like this root_dir seems to of been changed now you have to decalre root_dir also the bufnb is passed as the first argument now. If you want to use root_dir instead of root_markers. As I have to look in the package file to see the version of vue as vue 2 is vuels and vue 3 is volar couldnt just use the root_markers.

then what i do to setup all the mason servers that are registered:

Thanks @nick22985 , yeah root_markers worked for me.

[williamboman]

@nick22985 You don't need to loop over installed servers and only then call vim.lsp.config(). See mason-org/mason-lspconfig.nvim#544 (comment) and https://github.com/williamboman/nvim-config/tree/mason-v2-example for an example of how you can decouple the configuration in a cleaner (and intended) way.

[nick22985]

Okay cool thanks. Have changed it not use * for everything and after/ for the servers.
