Having trouble with folds and session restore

[adrian5]

I don't know if this is an issue with persisted.nvim or Neovim itself.

When loading a session, nvim experiences error E490: No fold found. This is apparently a telescope issue as well.

I can give up on folds from sessionoptions to prevent this error from affecting startup (session restore). Either way, folds won't work in the session-restored buffers unless I have nvim recompute them:

vim.api.nvim_create_autocmd("User", {
  desc = "Recompute folds after session is loaded",
  pattern = "PersistedLoadPost",
  group = vim.api.nvim_create_augroup("PersistedHooks", {}),
  callback = function()
    vim.defer_fn(function()
      vim.cmd("normal! zx")
    end, 50) -- Small delay seems necessary
  end
})

Do you experience this as well when restoring buffers and autoloading? I.e. za throws E490 unless you invoke zx first, or open another buffer.

If so, I wonder if you could add a workaround to the plugin itself. Maybe it misses some nvim default action when restoring buffers, the same way telescope does.

I don't recall ever coming across that error code. Are you on Neovim 0.9.2?

My sessionoptions are set in my config, here. I am using nvim-ufo these days too. Might be worth playing around with that

I couldn't nail it down, it's not your plugin and happens with plain :mksession an :source as well. I'm on Neovim 0.9.2.

I've now set up nvim-ufo as I simply don't have the time to dig any deeper; ufo seems to handle folds in sessions just fine. Maybe the problem will resolve itself once telescope and nvim-treesitter tackle (seemingly) related issues.

Thanks!

The joys of Neovim. Glad you got a resolution. My latest pain is Neovim seemingly exiting after holding down j too many times 😂
