Directory Node Expanded State

[jacob7395]

Hey,

I am trying to figure out if a directory node is open, is there a simple way to find this out.

This is what I have so far, I want to only trigger the edit if the node is expanded.

function nvimtree.collapse_dir()
    local node = api.tree.get_node_under_cursor()
    local is_folder = node.fs_stat and node.fs_stat.type == "directory" or false

    if is_folder == false  then
        return
    end

   api.node.open.edit()
end

Take a look at the node classes: https://github.com/nvim-tree/nvim-tree.lua/blob/master/lua/nvim-tree/_meta/api.lua

I think directory open should cover you.

node:is(DirectoryNode) might be useful as well.

That was it thanks, for future reference the bellow works for me;

function nvimtree.collapse_dir()
    local node = api.tree.get_node_under_cursor()
    local is_folder = node.fs_stat and node.fs_stat.type == "directory" or false

    if node:is(DirectoryNode) or node.open == false then
        return
    end

   api.node.open.edit()
end

I have one question, nvim is telling me id doesn't know what DirectoryNode is. I assume this is because I am missing some type def but the lua types are a bit of magic too me right now. If you know how to link the type so I assume my lsp knows that I am talking about that would be good to understand.

local DirectoryNode = require("nvim-tree.node.directory")

That is the class itself.

Unfortunately that is internal, however will work for you. Thanks for letting me know; we should expose it via API.
