How to open file/directory with a single mouse-click?

Right now 2-leftmouse is required to open a file/directory. I tried mapping to just leftmouse but it doesn't work properly. leftmouse does open the directory/file under the cursor with a single clock but it doesn't move the cursor to the file/directory I actually clicked.

local tree_cb = require'nvim-tree.config'.nvim_tree_callback
require'nvim-tree'.setup {
  view = {
    mappings = {
      list = {
        { key = { '<leftmouse>' }, cb = tree_cb("edit") },
      }
    }
  }
}

issue with only left mouse is that when clicking, the correct line is not focused. That's why double click is needed.

[astier]

I understand. Therefore the correct line should first be focused an than the node opened. Its possible in netrw and nerdtree.

@kyazdani42 I have been able to achieve single mouse click using the following code:

local function action_callback_for_tree(node)
  vim.cmd [[
  execute "normal! \<LeftMouse>"
  ]]
  local lib = require'nvim-tree.lib'
  local node = lib.get_node_at_cursor()
  if not node then return end
  print(node.absolute_path)
end

The idea was copied from https://github.com/preservim/nerdtree/blob/81f3eaba295b3fceb2d032db57e5eae99ae480f8/autoload/nerdtree/ui_glue.vim#L387

You can use the execute approach for all mouse events to make them possible on a single click.

I'll see what i can do about this :) If someone want's to open a PR, it would be gladly welcome too.

@atishay can you give more details in how to use that? Should I add it as a <LeftMouse> mapping for nvim-tree? Do I need to disable the <2-LeftMouse> one?

[atishay]

There was a focus bug in nvim. It was able to show the menu with one click but the focus needed to be on the right pane. The concept works in vim. I will like the nvim issue to this thread once I find it.

That may explain my problem. Thanks for letting me know (and for linking the issue when you find it)

Got this to work in nvim 0.8

local function single_click_edit(node)
  vim.defer_fn(function ()
    local win = vim.api.nvim_get_current_win()
    local view = require "nvim-tree.view"
    if view.get_winnr() ~= win then return end
    local actions = require'nvim-tree.actions.dispatch'
    actions.dispatch("edit")
  end, 10)
end

require('nvim-tree').setup({
  view = {
    mappings = {
      list = {
        { key = "<LeftRelease>", action= "single_click_edit", action_cb = single_click_edit},
      }
    }
  }
});

Very nice! Added to :help nvim-tree-mappings.

Closing as we have a valid workaround.

For people coming here:

Setting your own mapping in the configuration will soon be deprecated, see nvim-tree.on_attach for experimental replacement.

Deprecated and substituted with an experimental API?

The transition will be seamless, with no action needed or expected from users:

• existing mappings will continue to work
• an optional mechanism to automatically generate and migrate your mappings to on_attach will be available
• comprehensive transition documentation will be available

See #1579 for full details.

Thanks

How do you do it now? The mapping config thing's changed ;'(.

*edit:

Nevermind:

local function my_on_attach(bufnr)
	local api = require "nvim-tree.api"

	vim.keymap.set('n', '<LeftRelease>', function() 
		local api = require('nvim-tree.api')
		local node = api.tree.get_node_under_cursor()

		if node.nodes ~= nil then
			api.node.open.edit()
		end
	end, {})
end```
