How to avoid empty buffer from opening

[Dioswilson]

Hello, I am new to this plugin, and noticed that every time a session loads it also gets loaded an extra empty buffer which was not there before. Is it any way of getting rid of it?

That's odd and definitely not default behaviour. Suggest raising an issue and following the steps outlined in there

Spent like 5 hours trying to recreate the issue with minimal.lua, I disabled and renabled the plugin again with my init.lua and now it works. Guess we'll never know what happend

I think I was seeing this same behavior but was addressed by setting vim.opts.sessionoptions to omit blank, which is included by default.

I spent some time trying to dig into what's happening and I think it's some combination of netrw and/or starting neovim with arguments. Without yet uncovering the root cause, I have a solution with an autocmd/hook to delete all buffers for directories:

local persisted_hook_group = vim.api.nvim_create_augroup("PersistedHooks", {})
vim.api.nvim_create_autocmd({ "User" }, {
    pattern = "PersistedStateChange",
    group = persisted_hook_group,
    callback = function()
        local function dir_buffer_filter(buf)
            if not vim.api.nvim_buf_is_valid(buf) or not vim.api.nvim_buf_get_option(buf, 'buflisted') then
                return false
            end

            local filetype = vim.api.nvim_buf_get_option(buf, 'filetype')
            if filetype == 'netrw' then return true end

            local buftype = vim.api.nvim_buf_get_option(buf, 'buftype')
            if buftype == 'nofile' or buftype == 'prompt' then return true end

            local name = vim.api.nvim_buf_get_name(buf)
            local path = vim.loop.fs_realpath(vim.fn.expand(name))
            if path == nil then
                return false
            end
            return vim.fn.isdirectory(path) ~= 0
        end

        local buffers_to_del = vim.tbl_filter(dir_buffer_filter, vim.api.nvim_list_bufs())
        for _, buffer in ipairs(buffers_to_del) do
            vim.api.nvim_buf_delete(buffer, {})
        end
    end,
})
