How to disable dropbar for terminal tabs?

[AllergicMushroom]

I am using ToggleTerm with tab direction. However, I'd like to remove dropbar from those tabs.

There's an example in the readme to change bar name, but it doesn't work. How can I entirely disable dropbar for terminal tabs?

Use bar.enable for this, not bar.sources.

bar.sources only controls what dropbar shows after it has already attached. The default source function actually has a terminal branch:

if vim.bo[buf].buftype == 'terminal' then
  return {
    sources.terminal,
  }
end

So if you want no dropbar at all for ToggleTerm tab terminals, add the terminal check to bar.enable instead:

require('dropbar').setup({
  bar = {
    enable = function(buf, win, _)
      buf = vim._resolve_bufnr(buf)

      if
        not vim.api.nvim_buf_is_valid(buf)
        or not vim.api.nvim_win_is_valid(win)
      then
        return false
      end

      if vim.bo[buf].buftype == 'terminal' then
        return false
      end

      if
        vim.fn.win_gettype(win) ~= ''
        or vim.wo[win].winbar ~= ''
        or vim.bo[buf].ft == 'help'
      then
        return false
      end

      local stat = vim.uv.fs_stat(vim.api.nvim_buf_get_name(buf))
      if stat and stat.size > 1024 * 1024 then
        return false
      end

      return vim.bo[buf].ft == 'markdown'
        or pcall(vim.treesitter.get_parser, buf)
        or not vim.tbl_isempty(vim.lsp.get_clients({
          bufnr = buf,
          method = 'textDocument/documentSymbol',
        }))
    end,
  },
})

That is basically the documented default enable function with one extra early return for terminal buffers.

If your ToggleTerm buffers use a custom filetype and you only want to exclude those, check the buffer with :setlocal buftype? filetype? inside the terminal tab and make the condition narrower, for example:

if vim.bo[buf].buftype == 'terminal' and vim.bo[buf].ft == 'toggleterm' then
  return false
end

Dear @cookesan ,

Thank you for your message. I finally managed to make it work using only the

      if vim.bo[buf].buftype == 'terminal' then
        return false
      end

part. Using the whole provided bar.enabled resulted in the dropbar still being there, and no error message.
