How to create an auto-command to automatically load the session?

[gbroques]

Can you help me write an auto-command to load the session automatically?

Here's what I tried:

vim.api.nvim_create_autocmd("VimEnter", {
  group = vim.api.nvim_create_augroup("restore_session", { clear = true }),
  callback = function()
    require("persistence").load()
  end,
  nested = true,
})

This loads the session, but my syntax highlighting breaks.

I have treesitter lazy loaded on { 'BufReadPre', 'BufNewFile' } events.

Users on Reddit reported a similar problem:

vim.schedule(function()
  require('persistence').load()
end)

You can even try unwrapping it from the event. You can even try extracting it from the autocmd.

I'm not sure what exactly is causing this behavior — the filetypes for visible buffers aren't being assigned properly after loading a session right after the VimEnter event.

@drowning-cat I'm sorry, what do you mean?

Can you clarify please?

Remove autocmd, put only vim.schedule.

Ah ok, yes this works too and seems simpler:

{
  'folke/persistence.nvim',
  config = function()
    require('persistence').setup()

    vim.schedule(function()
      require('persistence').load()
    end)
  end
}

Thank you for that!

You can also write it like this:

{
  'folke/persistence.nvim',
  opts = {},
  init = function()
    vim.schedule(function()
      require('persistence').load()
    end)
  end,
}

I have an issue in autocmd approach when I add a new plugin, on startup lazy runs a floating window, so either it loads a session into a floating window or I swap to a background window, load it and get back to lazy, but then lazy gets closed as soon as it's done with installation.
not a big deal, I don't add plugins often, but wonder did you solve it?

{
  'folke/persistence.nvim',
  opts = {},
  init = function()
    vim.schedule(function()
      if vim.bo.ft == 'lazy' then
        vim.cmd.quit()
      end
      require('persistence').load()
    end)
  end,
}
