When using Snacks.picker, which shows the content of a buffer, it launches an additional dropbar.nvim

[vgalovic]

Hi, as I mentioned in the title, when I run Snacks.picker.buffers() or Snacks.picker.lines(), it also launches an additional dropbar. Is there a way to stop the dropbar from launching when I open the picker?

You can figure out what distinguishes a snacks picker buffer or window (e.g. it may have filetype 'snacks_picker', I dont't use it so I don't really know if it's true), then add it to the enable function, like this:

require('dropbar').setup({
  bar = {
    enable = function(buf, win)
      if is_snacks_picker(buf, win) then
        return false
      end
      -- some other logic ...
    end
  }
})

I use that same picker layout and I actually find it useful to have the dropbar there :D

But, Snacks buffers, follow the pattern snacks_*, so you can use that, and a more geneic way of disabling it could be to do it when the buffer has a type (vim.bo.buftype) defined, normally those are special puropse.

I'm encountering an error when trying to enable dropbar.nvim with the enabled function. Here’s the configuration snippet:

return {
  {
    'Bekaboo/dropbar.nvim',
    opts = {
      bar = {
        enable = function(buf, win, _)
          return true
        end,
      },
    },
  },
}

When I open the Snacks picker, I get the following error:

E5108: Error executing lua: ...ov/.local/share/nvim/lazy/snacks.nvim/lua/snacks/win.lua:700: BufWinEnter Autocommands for "*": Vim(append):E36: Not enough room

Did anyone manage to solve this?

I had a lot of issues disabling Dropbar in the Snacks picker preview. In my understanding of the issue, Snacks disables winbars by default, but plugins like Dropbar still create a winbar for the Snacks picker because Snacks use a regular buffer (e.g., a Lua file) to show a preview, and plugins that draw winbars can't differentiate it. I couldn't find an elegant way to disable winbars only for the Snacks picker, so I disabled them for all floating windows.

I don't know if this will fully solve the problem for you, but here is my autocommand that disables winbars for all floating windows:

-- Disable winbar for floating windows
vim.api.nvim_create_autocmd("BufWinEnter", {
	callback = function()
		local win = vim.api.nvim_get_current_win()
		local config = vim.api.nvim_win_get_config(win)

		-- Check if the current window is floating
		if config.relative ~= "" then
			-- Disable winbar for any floating window
			vim.wo[win].winbar = ""
			vim.w[win].winbar_no_attach = true
		end
	end,
})

Thanks a lot, that seems to be working!

This disabling does not seem to work on nvim 0.11.0.
