[Help] How do i make the CWD change when I load a session via the telescope picker?

[Ajaymamtora]

This is my config:

    local opts = {
      autostart = true, -- Automatically start the plugin on load?
      save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"), -- directory where session files are saved
      silent = true, -- silent nvim message when sourcing session file
      -- use_git_branch = false, -- create session files based on the branch of a git enabled repository
      -- default_branch = "main", -- the branch to load if a session file is not found for the current branch
      autosave = true, -- automatically save session files when exiting Neovim
      -- should_autosave = function()
      --   return is_only_neotree_and_empty_buffer()
      -- end, -- function to determine if a session should be autosaved
      -- should_save = function()
      --   return true
      -- end,
      autoload = true,
      -- on_autoload_no_session = nil, -- function to run when `autoload = true` but there is no session to load
      on_autoload_no_session = function()
        vim.notify("No existing session to load.")
      end,
      follow_cwd = true, -- change session file name to match current working directory if it changes
      -- allowed_dirs = nil, -- table of dirs that the plugin will auto-save and auto-load from
      -- ignored_dirs = nil,
      -- ignored_branches = nil, -- table of branch patterns that are ignored for auto-saving and auto-loading
      telescope = {
        mappings = { -- table of mappings for the Telescope extension
          copy_session = "<C-c>",
          change_branch = "<C-b>",
          delete_session = "<C-d>",
        },
        icons = { -- icons displayed in the picker, set to nil to disable entirely
          branch = icons.common.git .. "",
          dir = icons.common.folder_open .. "",
          selected = icons.common.trace .. "",
        },
      },
    }

And when i load a session, the CWD stays the same.

I assume follow_cwd is used for this? but it doesnt seem to work for me

This seems to work but idk if the path decode function is fully correct

    local function decode_session_path(session_file)
      local encoded_path = session_file:gsub("^" .. vim.pesc(save_dir), ""):gsub("%.vim$", "")
      local decoded_path = encoded_path:gsub("%%", "/")
      return "/" .. decoded_path -- Add leading slash
    end
    local function load_decoded_session()
      local session_file = vim.v.this_session
      if session_file and session_file ~= "" then
        print("SESSION POST:", session_file)
        print("OTHER POST", vim.g.persisted_loaded_session)

        local decoded_path = decode_session_path(session_file)
        print("Decoded session path: " .. decoded_path)
        print("Attempting to change directory to: " .. decoded_path)
        vim.cmd("cd " .. vim.fn.fnameescape(decoded_path))
        print("After forced cd - Current working directory: " .. vim.fn.getcwd())
      else
        print("No valid session file found")
      end
    end
    vim.api.nvim_create_autocmd({ "User" }, {
      pattern = "PersistedTelescopeLoadPost",
      group = group,
      callback = function()
        vim.defer_fn(function()
          load_decoded_session()
        end, 200)
      end,
    })

No idea.

Is there anything in the session file that stores the cwd? Otherwise, I guess you'd need to traverse the folder structure until you find a .git folder. Something like nvim-rooter looks like it does this.

[Ajaymamtora]

I dont think there is, also thats close but not what im looking for, my code will just try and CD to the folder that the session is for, not try and work out the project root - so it should CD to the path displayed in the telescope picker. No worries anyway I think my code does what I need but wasnt sure if there was a built in way to do it

[Ajaymamtora]

I had to add a 200 ms delay in PersistedTelescopeLoadPost to ensure that vim.v.this_session was updated - surely this is a bug? at this point the session should be loaded? The value is the same in pre and post.
