[BUG] ToggleTermSetName does not work with count

[abhinavnatarajan]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Calling ToggleTermSetName with a count opens the dialogue to enter a new name, and typing a name and hitting <CR> results in the error "attempt to index local 'term' (a nil value)".

Expected Behavior

The specified terminal should be renamed without error.

Steps To Reproduce

1. Minimal init.lua to reproduce the above behaviour:

local lazypath = vim.fn.stdpath('data') .. '/lazy/lazy.nvim'
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    'git',
    'clone',
    '--filter=blob:none',
    'https://github.com/folke/lazy.nvim.git',
    '--branch=stable', -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

-- Lazy load plugins
require("lazy").setup {
  {
    'akinsho/toggleterm.nvim',
    version = "*",
    lazy = true,
    cmd = {
      'ToggleTerm',
      'TermSelect',
      "ToggleTermSendCurrentLine",
      "ToggleTermSendVisualLines",
      "ToggleTermSendVisualSelection",
      "ToggleTermSetName",
    },
    keys = { [[<C-`>]] },
    config = function ()
      require("toggleterm").setup {
        open_mapping = [[<C-`>]],
        insert_mappings = true, -- whether or not the open mapping applies in insert mode
        terminal_mappings = true, -- whether or not the open mapping applies in the opened terminals
        close_on_exit = true, -- close the terminal window when the process exits
        -- Change the default shell. Can be a string or a function returning a string
        shell = vim.o.shell,
        auto_scroll = true, -- automatically scroll to the bottom on terminal output
        -- This field is only relevant if direction is set to 'float'
      }
	  vim.keymap.set('n', '<A-r>', '<CMD>ToggleTermSetName<CR>', {noremap = true})
    end
  }
}

2. Run:
   a. Create two terminals with <C-`><Esc>2<C-`><Esc>.
   c. Type 2<A-r>.

Environment

- OS: Ubuntu 22.04.2 LTS running as a WSL2 distro in Windows 11
- neovim version: 0.9.2
- Shell: bash
- Terminal: wezterm

Anything else?

Thanks for your work on this plugin, I rely on it quite extensively!
