howto pin a buffer through sessions switching?

[tmpm697]

Your Persisted.nvim config

  {
    name = "PersistedHooks",
    {
      "User",
      function(session)
        require("persisted").save()

        -- Delete all of the open buffers
        vim.api.nvim_input("<ESC>:%bd!<CR>")

        -- Don't start saving the session yet
        require("persisted").stop()
      end,
      opts = { pattern = "PersistedTelescopeLoadPre" },
    },
  },

Describe

I want to pin / sticky a buffer through sessions save/switching, more verbose below:

Reproduce

1. at sessionA
2. :term
3. <C-\><C-n> to bring terminal buffer to normal mode (you can now switch to other buffers)
4. open some buffers under sessionA
5. :SessionSave
6. switch to sessionB --> with above minimal config, terminal buffer from sessionA will be deleted

How to not save terminal buffer from sessionA at step 5? other buffers at step 4 should still be saved to sessionA.

When switch to sessionB at step 6, terminal buffer from sessionA should be avail/merged to sessionB buffers list

Unfortunately this isn't possible with this plugin. It makes use of the inbuilt :mks function (:h mks) for saving and source for loading. Unless there's some way you can restore that buffer via one of the event callbacks?

for my thinking, i'd need to a label/uid for buffer to exclude it from saving, if this plugins base on builtin mks then mks should have a way to do this that idk.

No idea unfortunately but I'm more than happy to accept a PR
