update_focused_file doesn't focus file in another repo

No

Describe the solution you'd like
With the settings update_focused_file = { enable = true, update_root = false } when I open a file in repo A the tree is focused on the folder where the file is located and the root folder is the repo's base, where .git folder is. This is working as expected. However, if I open another file in repo B, the tree doesn't update to repo B's base.

I tried setting update_focused_file.update_root = true and the tree does follows the file in repo B, however, the root folder is not repo B's base, but the folder deep inside where the file is located. I would like for nvim-tree to always make the repo's base the root folder, not the folder where the file is located as root.

Describe alternatives you've considered
I looked through the docs have not seen a option to achieve what I mentioned.

update_root is not quite the right place for this; it is for the current file.

1. This could be done with API: :h nvim-tree-api.tree.change_root(). We need a means to set {path} to the file's repository root.

Alternatives:

2. tree.change_root({git_base = true})
3. provide git.base({path}) to pass to change_root

I'm leaning towards a recipe for 1.

Have a play with this hacky mapping in your on_attach:

  vim.keymap.set("n", "x", function()
    local node = api.tree.get_node_under_cursor()

    local cmd = { "git", "-C", vim.fs.dirname(node.absolute_path), "rev-parse", "--show-toplevel" }

    -- strip trailing newline
    local toplevel = vim.fn.system(cmd):sub(0, -2)

    local stat, _ = vim.loop.fs_stat(toplevel)
    if stat and stat.type == "directory" then
      -- change to toplevel
      api.tree.change_root(toplevel)
    else
      -- failure message
      print(toplevel)
    end
  end, opts("CD git toplevel"))

Hi @alex-courtis I tried your code and I do see that the x shows up as CD git toplevel but it doesn't work. I use cljoly/telescope-repo.nvim to open a file in another repo but when I opened nvim-tree it doesn't set that opened file's repo as root. What I'm trying to do is use only one neovim session and use telescope-repo to open another repo and wanting nvim-tree to automaticall set that newly opened repo as root.

What happens when you execute the mapping? Can you print toplevel to see what was retrieved?

Baby steps. Let's get this going with a mapping then we can automate.
