Picker switches projects without removing opened buffers

[knmac]

I am using Snacks.picker.projects() to switch between saved sessions (created by olimorris/persisted.nvim). This works well if I don't have any buffers open yet. However, these buffers don't get removed when switching to another sessions.

For example, consider 2 session session_1 and session_2 currently saved as follow:

-> session_1: buffer_a, buffer_b
   session_2: buffer_c, buffer_d

As I switch from session_1 to session_2, I will have something like this:

   session_1: buffer_a, buffer_b
-> session_2: buffer_a, buffer_b, buffer_c, buffer_d

From olimorris/persisted.nvim, this issue is addressed by setting up an autocmd for event PersistedTelescopeLoadPre as follow:

vim.api.nvim_create_autocmd("User", {
  pattern = "PersistedTelescopeLoadPre",
  callback = function(session)
    -- Save the currently loaded session using the global variable
    require("persisted").save({ session = vim.g.persisted_loaded_session })

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

However, this PersistedTelescopeLoadPre event seems to be closely integrated with Telescope. So replacing PersistedTelescopeLoadPre with PersistedLoadPre doesn't seem to fix the problem.

Question: Is it possible to implement something similar to PersistedTelescopeLoadPre event in Snacks? Or if there are other solutions?

Thank you!

That's just how persisted works and should be fixed there. They should fire an event when a session will be loaded.
That's not the task of snacks.
