Nvim-lspconfig: Get root directory

[Kyle-Thompson]

Is there a way to query what the LSP detects as the root directory? I can't seem to find one.

[singalhimanshu]

There's a root_dir parameter with most of the language servers that you can set to detect root directory.

[Kyle-Thompson]

What would be the syntax to query that? Like with clangd or rust analyzer for example if it's specific to each LS.

I have an understanding of how to set the root directory but I'm still unclear on how to query its value.

[singalhimanshu]

You can do something like this :

local nvim_lsp = require'nvim_lsp'
nvim_lsp.clangd.setup{
  root_dir = nvim_lsp.util.root_pattern('.git');
}

@himansingh241 you're misunderstanding him. He's asking how query for the _calculated value_ of root_dir, not how to set it.

So for example, given this:

nvim_lsp.clangd.setup {
  root_dir = nvim_lsp.util.root_pattern('foo', 'bar', 'baz')
}

What's the value of root_dir when the language server starts in some directory X?

I had the same issue. Solved it with #363.

you could use checkhealth with this branch https://github.com/neovim/neovim/pull/12578

@Kyle-Thompson Technically this is exposed via :help vim.lsp.buf.list_workspace_folders() which stores the first root directory on server intitialization by default
