[filesystem] collapse_directory

[MunifTanjim]

How do I do this?

  collapse_directory = function(state)
    local node = state.tree:get_node()
    if node.type ~= "directory" or not node:is_expanded() then
      node = state.tree:get_node(node:get_parent_id())
    end
    if node.type == "directory" then
      -- collapse node
      -- focus node
    end
  end,

I want to collapse a directory and then focus it.

The collapse is just the standard NuiNode collapse followed by a NuiTree render. The focus node method is a custom Neo-tree function:

  collapse_directory = function(state)
    local node = state.tree:get_node()
    if node.type ~= "directory" or not node:is_expanded() then
      node = state.tree:get_node(node:get_parent_id())
    end
    if node.type == "directory" then
      -- collapse node
      node:collapse()
      state.tree:render()
      -- focus node
      require("neo-tree.ui.renderer").focus_node(state, node:get_id())
    end
  end,

What I should have said was that this functionality already exists, it is the "close_node" command, mapped to C by default. That built-in function also works with nested files.

close_node will close node when cursor is on file within that node. toggle_node has to be on directory itself. Could toggle_node also toggle node if cursor is on file within that node?
