Description

When in a floating window with vim.g.canola.delete = "wipe", deleting the buffer that's currently being edited doesn't affect the buffer in the background. I've actually handled a similar thing before with fzf-lua, to allow deleting the current buffer in the picker. Here's the code for some inspiration:

-- Return a list of the open bufnrs, sorted by how recently they were accessed
local function get_sorted_buflist()
  local info = vim.fn.getbufinfo({ buflisted = 1, bufloaded = 1 })

  -- Take the full info and turn it into just the bufnrs
  local bufnrs = {}
  for index, current in ipairs(info) do
    bufnrs[index] = current.bufnr
  end

  return bufnrs
end

-- Custom action that allows deleting the current buffer. If you do, it swaps to
-- the last buffer you used!
local function delete_buffer_action(selected, opts)
  for _, sel in ipairs(selected) do
    local file = path.entry_to_file(sel, opts)
    local buf_to_delete = file.bufnr

    -- If the current file has unsaved changes, prompt the user to save
    local is_dirty = utils.buffer_is_dirty(buf_to_delete, true, false)
    local save_dialog = function()
      return utils.save_dialog(buf_to_delete)
    end

    if buf_to_delete and (not is_dirty or vim.api.nvim_buf_call(buf_to_delete, save_dialog)) then
      local sorted_buflist = get_sorted_buflist()
      local current_buf = sorted_buflist[1]

      if buf_to_delete == current_buf then
        local windows = vim.fn.win_findbuf(current_buf)

        -- We need the buffer we accessed most recently after the current buf.
        -- We can't use alternate file here, because the REAL current buf is
        -- actually the picker - so we need to go two files back.
        local new_buf = sorted_buflist[2]

        for _, win in ipairs(windows) do
          vim.api.nvim_win_set_buf(win, new_buf)
        end
      end

      vim.api.nvim_buf_delete(buf_to_delete, { force = true })
    end
  end
end

Minimal reproduction

Can reproduce with this config:

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()
require("lazy").setup({
  spec = {
    {
      "barrettruth/canola.nvim",
      branch = "canola",
      init = function()
        vim.g.canola = {
          delete = {
            wipe = true,
          },
        }
      end,
    },
  },
})

Working great, thanks! I'm running out of issues to report, which is a good sign.
