Sorting files numerically

[zefr0x]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I have a directory that has number-named files.
For example NvimTree will display them like that:

1
10
11
12
13
14
15
16
17
18
19
2
20
3
4
5
6
7
8
9

But the normal order I want them to be in is like:

1
2
3
4

6

8
9
10
11
12

16
17
18
19
20

It's the same default behavior of the ls GUN utility in Linux, but the ls has an option -v to treat filename numerically. https://unix.stackexchange.com/questions/33909/list-files-sorted-numerically

Most times I need numbered files sorted with the numerically normal order so I can walk between them easily.

Describe the solution you'd like
Maybe adding a new type to the sort_by option to do that type of sorting.

Describe alternatives you've considered
Maybe I just can create a function to do that since sort_by option support passing a function.

You can add this functionality yourself. See :help nvim-tree.sort_by

This might get you started:

  local sort_by = function(nodes)
    table.sort(nodes, function(a, b)
      local a_num = string.match(a.name, "^[0-9]+")
      local b_num = string.match(b.name, "^[0-9]+")
      if a_num and b_num then
        return a_num < b_num
      else
        -- we need to do something here
        return false
      end
    end)
  end
