Highlight nvim tree directory that contains file I found with telescope

Question

Is there a way to highlight a directory of a found file?

For example I look for a specific file with telescope and when I open it, my nvim-tree is updated and shows me parent directory?

Answer 1

You can jump to the file in current buffer by using :NvimTreeFindFile. To do this automatically upon opening the file in telescope, you need to "overload" the open action of Telescope (called select_default, on - carriage return) to run NvimTreeFindFile command just after you open the file. You can do so by using transform_mod:

In ~/.config/nvim/init.vim put this configuration:

lua << EOF

local transform_mod = require('telescope.actions.mt').transform_mod
local actions = require('telescope.actions')
local mod = {}
mod.open_in_nvim_tree = function(prompt_bufnr)
    local cur_win = vim.api.nvim_get_current_win()
    vim.cmd("NvimTreeFindFile")
    vim.api.nvim_set_current_win(cur_win)
end

mod = transform_mod(mod)

require("telescope").setup{
    defaults = {
        mappings = {
            i = {
                ["<CR>"] = actions.select_default + mod.open_in_nvim_tree,
            },
            n = {
                ["<CR>"] = actions.select_default + mod.open_in_nvim_tree,
            },
        },
    },
}
EOF

Short answer

Nvim-tree provide this behavior out of the box.

You can achieve this by adding next lines for example:

require("nvim-tree").setup {
  sync_root_with_cwd = true,
  respect_buf_cwd = true,
  update_focused_file = {
    enable = true,
    update_root = {
      enable = true,
    }
  },
}

Explanation

sync_root_with_cwd

Changes the tree root directory on DirChanged and refreshes the three. (from h: sync_root_with_cwd)

respect_buf_cwd

Will change cwd of nvim-tree to that of new buffer's when opening nvim-tree. (from h: respect_buf_cwd)

update_focused_file

Update the focused file on BufEnter, up-collapses the folders recursively until if finds the file. (from h: update_focused_files)

update_focused_file.update_root

Update the root directory of the tree if the file is not under current root directory. It prefers vim's cwd and root_dirs. Otherwise it falls back to the folder containing the file. (from h: update_root)
