feat: add note about root_dir for nvim-lspconfig

[martenmatrix]

nvim-lspconfig is the official collection of LSP server configurations by NeoVim. Therefore, the majority of NeoVim users use those defaults. It should be included how to prevent attaching ts_ls and denols to a buffer.

Additionally, single_file_support was renamed to workspace_required in NeoVim.

I apologize for not creating an issue for this. I hope that is fine.

Thanks for the contribution! The single_file_support → workspace_required update is needed, but there are a few issues to address:

1. root_dir example is incorrect

The added code block has:

root_dir = {"package.json"},

But root_dir expects a function, not a table of strings. It should use root_pattern from lspconfig:

root_dir = require("lspconfig").util.root_pattern("package.json"),

As written, this would break users' configs.

2. Kickstart.nvim section not updated

The kickstart.nvim example further down the page still uses single_file_support = false — this should also be updated to workspace_required = true for consistency.

3. Fragile GitHub line-number link

The link to lsp/ts_ls.lua#L56-L68 will break as that file changes. Consider linking to the file without line numbers, or just describing the behavior inline.

1. root_dir = {"package.json"} is still wrong for the ts_ls sample. root_dir needs a resolver function here; use require("lspconfig").util.root_pattern("package.json") or keep this example on the native root_markers API.
2. The Kickstart.nvim block still uses single_file_support = false for both ts_ls and denols, so the page now gives conflicting advice after the text switched to workspace_required = true. Please update that block too.

• nit: the GitHub link to lsp/ts_ls.lua#L56-L68 is fragile; link to the file or explain the behavior inline.

Two blockers still need fixing before this page can safely recommend the new Neovim config.

1. root_dir = {"package.json"} is not a valid nvim-lspconfig resolver for ts_ls; use require("lspconfig").util.root_pattern("package.json"), or keep the example on native root_markers instead.
2. The Kickstart.nvim block still says single_file_support = false for both ts_ls and denols, while the text above moved to workspace_required = true. Update that block too so the page does not give conflicting configuration.

• nit: the lsp/ts_ls.lua#L56-L68 link is line-number fragile; link to the file or describe the behavior inline.

The Neovim examples now use workspace_required and a root_pattern(...) resolver consistently. One repo-convention blocker remains:

1. last_modified: 2026-02-19 still has the old date even though this page now changes the documented Neovim setup. Please bump it for this content update.
