Description

Some builtin Neovim operators (and some custom operators) do perform an action when executed with a opertor-pending mode keymap that doesn't move the cursor nor visually selects any region. d doesn't delete anything, but empties the content of the " register (just like y). c starts insert mode in current location (just like if i was pressed). Linewise operators like > still indent the whole line, etc.

When mini.ai can't find a textobject, it behaves in the aforementioned way.

Reproduction

1. Create separate 'nvim-repro' config directory:

   • '~/.config/nvim-repro/' on Unix
   • '~/AppData/Local/nvim-repro/' on Windows

2. Inside 'nvim-repro' directory create a file named 'init.lua'.
   Populate it with the following content:

   -- Clone latest 'mini.nvim' (requires Git CLI installed)
   vim.cmd('echo "Installing `mini.nvim`" | redraw')
   local mini_path = vim.fn.stdpath('data') .. '/site/pack/deps/start/mini.nvim'
   local clone_cmd = { 'git', 'clone', '--depth=1', 'https://github.com/echasnovski/mini.nvim', mini_path }
   vim.fn.system(clone_cmd)
   vim.cmd('echo "`mini.nvim` is installed" | redraw')
   
   -- Make sure 'mini.nvim' is available
   vim.cmd('packadd mini.nvim')
   require('mini.deps').setup()
   
   -- Add extra setup steps needed to reproduce the behavior
   -- Use `MiniDeps.add('user/repo')` to install another plugin from GitHub

3. Run NVIM_APPNAME=nvim-repro nvim (i.e. execute nvim with NVIM_APPNAME environment variable set to "nvim-repro"). Wait for all dependencies to install.

4. i"foo"<esc> to write "foo" in the current buffer

5. yy and then p to copy "foo" and paste it

6. yi'. An error message will be displayed explaining that no textobject i' could be found

7. p to paste. Nothing will be pasted

Note. the same can be tested with the other operators mentioned above, not only y.

Thanks for the issue!

Yeah, indeed I can reproduce. This is not a great behavior that can be improved. I'll take a look at #1943.

[echasnovski]

After thinking about it, I think this is more of an issue in Vim (not even Neovim) itself. More discussion and details in #1943.

And as a note: I can not reproduce the same behavior of steps 4-7 if step 6 is di'.
