feature request: suppress "no longer available"

[anuramat]

Did you check existing requests?

• I have searched the existing issues

Describe the feature

When deleting a file that is open, the corresponding buffer is still loaded and you get a "no longer available" message.
It would be nice to have an option that would automatically delete buffers that correspond to deleted files, and save+reopen buffers for the moved files.

Provide background

Moving/deleting open files is annoying atm.

Additional details

Got the idea from tpope/vim-eunuchs :Remove

Yeah, this would be possible. The current behavior intentionally leaves the buffers in-place as sort of an extra protection from data loss, but we could potentially add another config option to remove those buffers. Will add to my backlog

Astrocommunity gets this done here. My lua-fu is too weak so my struggles to piece together something distro-agnostic are real Maybe someone can improve on this?

vim.api.nvim_create_autocmd("User", {
  desc = "Close buffers when files are deleted in Oil",
  pattern = "OilActionsPost",
  callback = function(args)
    if args.data.err then return end
    for _, action in ipairs(args.data.actions) do
      if action.type == "delete" then
        local _, path = require("oil.util").parse_url(action.url)
        local bufnr = vim.fn.bufnr(path)
        if bufnr ~= -1 then vim.cmd.bwipeout { bufnr, bang = true } end
      end
    end
  end,
})

This is sorta working but I am always left with an orphaned buffer with foo.txt loaded.

echo foo > {foo,bar}.txt
vi {foo,bar}.txt

With the 2 buffers now open, I now:

1. Run Oil
2. dd foo.txt and bar.txt
3. :w and confirm

The bar.txt buffer is removed but the other is still showing despite foo.txt being deleted from the directory.
