Would there be any way to stack nvim-tree with another plugin in the same sidebar column?

[mrjones2014]

I've been using nvim-ide for several months now, the main reason being that I like the ability to have multiple components stacked in the same column/sidebar. However pretty much the only components I actually use from it are the bufferlist and file tree, and sometimes symbols outline (see screenshot, this is how I usually have it when I toggle it open).

Would there be any way to do something like this with nvim-tree? I could use aerial.nvim for the symbols outline and it'd be trivial enough to write my own bufferlist component.

aerial and nvim-tree at the left would work quite nicely. I might use that.

RE buffer list you can use B api.tree.toggle_no_buffer_filter

This might be possible without any nvim-tree or aerial changes. Experimenting.

Thank you

Aerial added aerial.open_in_win(target_win, source_win) and I've got a hackjob somewhat working like this:

local width = 35

return {
  'nvim-tree/nvim-tree.lua',
  cmd = 'Tree',
  dependencies = {
    'stevearc/aerial.nvim',
    config = function()
      require('aerial').setup({
        layout = {
          max_width = { width },
          min_width = { width },
          placement = 'edge',
        },
        attach_mode = 'global',
        keymaps = {
          ['<C-j>'] = false,
          ['<C-k>'] = false,
          ['<C-y>'] = 'actions.up_and_scroll',
          ['<C-e>'] = 'actions.down_and_scroll',
        },
      })
    end,
  },
  config = function()
    require('legendary').command({
      'Tree',
      function()
        local curwin = vim.api.nvim_get_current_win()
        local a = require('aerial')
        local tree = require('nvim-tree.api').tree
        tree.open({ path = vim.loop.cwd() })
        local orig = vim.opt.splitbelow
        vim.opt.splitbelow = false
        vim.cmd(('%ssp'):format(width))
        vim.cmd('wincmd j')
        vim.opt.splitbelow = orig
        vim.schedule(function()
          a.open_in_win(0, curwin)
          vim.api.nvim_win_set_width(0, width)
          -- put cursor focus back where it was
          vim.api.nvim_set_current_win(curwin)
        end)
      end,
    })
    require('nvim-tree').setup({ view = { side = 'right' } })
  end,
}

Now I just need to create a bufferlist component for myself.

RE buffer list you can use B api.tree.toggle_no_buffer_filter

I'd like to have both a file tree and a bufferlist though, so I'd need two instances of nvim-tree to do that, which I'm not sure is possible?

[mrjones2014]

Hmm, with this code, nvim-tree seems to lose track of its buffer, and tree.close() closes the Aerial window instead.

[alex-courtis]

Wow... thanks for the quick feature @stevearc

Implementing the same API as aerial in nvim-tree seems the best course of action: allow full control for the user instead of relative positioning.
