API: how to query node whether it's a directory (in a consistent way)?

[przepompownia]

vim/vim#12087 (comment) is still not fixed so I need to use some custom replacement for :tab drop.

Currently in on_attach I have to recognize directories by looking into details

    vim.keymap.set(
      'n',
      '<CR>',
      injectNode(function(node)
        if node.name == '..' or node.type == 'directory' then
          treeapi.node.open.edit()

          return
        end
        treeapi.tree.close()
        base.tab_drop_path(node.absolute_path)
      end),
      {buffer = bufnr, noremap = true}
    )

It would be good to have is_directory() directly on each node.

I'm not sure what you're looking for, nodes are just tables, so to check whether a node is a directory you have two options:

• check if node.type is 'directory' (like you did)
• check if node.nodes is a table

Then there is the root node, which actually is not a node, since it's a table with only the name field.

I'm looking for more clean method but (as you suggest too) it seems that currently we have to guess by internals of node.

Yes, if you really want a cleaner way to write it you can create your own local function that does it so that you don't have to write the same things several times.
