feature: auto load session on directory open

[aymanbagabas]

Did you check the docs?

• [X] I have read all the persistence.nvim docs

Is your feature request related to a problem? Please describe.

I would like to have a similar behavior to VSCode. When I open a project directory I would like the session to be loaded with all the previous buffers, options, and window sizes.

Describe the solution you'd like

Load session on directory open.

seems #13 and https://github.com/folke/persistence.nvim#-usage won't do auto

but we can write an auto command do this i think.

vim.api.nvim_create_autocmd('VimEnter', opts) -- not sure if is VimEnter event.

you can do something like this

local persistenceGroup = vim.api.nvim_create_augroup("Persistence", { clear = true })
local home = vim.fn.expand "~"
local disabled_dirs = {
  home,
  home .. "/Downloads",
  "/private/tmp",
}

-- disable persistence for certain directories
vim.api.nvim_create_autocmd({ "VimEnter" }, {
  group = persistenceGroup,
  callback = function()
    local cwd = vim.fn.getcwd()
    for _, path in pairs(disabled_dirs) do
      if path == cwd then
        require("persistence").stop()
        return
      end
    end
    if vim.fn.argc() == 0 and not vim.g.started_with_stdin then
      require("persistence").load()
      require("nvim-tree.api").tree.toggle(false, true)
    else
      require("persistence").stop()
    end
  end,
  nested = true,
})

sorry, not interested in adding this

@madmaxieee Did it work for ? For me the session load does not happen when I open vim without any args although the autocmd is triggered. However if I do :=require("persistence").load() the session does gets loaded.

@rbhanot4739 yes it works for me. for extra context, I set vim.g.started_with_stdin using this autocmd, which I forgot to include int the previous coomment:

-- disable persistence if nvim started with stdin
vim.api.nvim_create_autocmd({ "StdinReadPre" }, {
  group = persistence_group,
  callback = function()
    vim.g.started_with_stdin = true
  end,
})

hope that helps.
