[Bug] Files renaming issue on Windows 11 Pro

[pidgeon777]

I'm on Windows 11 Pro, using Lazyvim.

Config:

return {
  {
    "gabrielpoca/replacer.nvim",
    keys = {
      {
        "<leader>hr",
        function()
          require("replacer").run()
        end,
        desc = "run replacer.nvim",
      },
      {
        "<leader>hs",
        function()
          require("replacer").save({})
        end,
        desc = "save replacer.nvim",
      },
    },
    opts = function(_, opts)
      local def_opts = {
        save_on_write = true,
        rename_files = true,
      }

      local my_opts = {
        save_on_write = false,
        rename_files = true,
      }

      opts = vim.tbl_deep_extend("force", opts or {}, my_opts)

      return opts
    end,
    enabled = true,
  },

  -- Which-key sub-menus
  {
    "folke/which-key.nvim",
    optional = true,
    opts = {
      defaults = {
        mode = { "n", "v" },
        ["<leader>h"] = { name = "+replacer.nvim" },
      },
    },
  },
}

I have a buffer named work.csv with this content:

work,InternalComponent.vhd
work,InternalEntity.vhd
work,TestEntity.vhd

pwd returns: C:\Work\Test.

I populate the quickfix list with the buffer content so that I obtain:

work.csv|1 col 1| work,InternalComponent.vhd
work.csv|2 col 1| work,InternalEntity.vhd
work.csv|3 col 1| work,TestEntity.vhd

Then I execute require("replacer").run() to make the quickfix list editable.

I edit it this way:

aaaawork.csv|1 col 1| work,InternalComponent.vhd
aaaawork.csv|2 col 1| work,InternalEntity.vhd
aaaawork.csv|3 col 1| work,TestEntity.vhd

Finally, I execute require("replacer").save({}) to save the changes.

As a result, the buffer filename is not updated to aaaawork.csv, which would be the expected behavior.

Also, what would happen to the final buffer filename if I edited the quickfix list this way?

aaaa\work.csv|1 col 1| work,InternalComponent.vhd
bbbb\work.csv|2 col 1| work,InternalEntity.vhd
cccc\test.csv|3 col 1| work,TestEntity.vhd

Finally, what should the path separator on Windows be in the quickfix list before saving it, so that the new buffer filename/location is updated correctly?
