The easysession.el Emacs package is a lightweight session manager for Emacs that can persist and restore file editing buffers, indirect buffers (clones), Dired buffers, the tab-bar, and Emacs frames (including or excluding the frame size, width, and height). It offers a convenient and effortless way to manage Emacs editing sessions and utilizes built-in Emacs functions to persist and restore frames.

Key features include:

• Minimalistic design focused on performance and simplicity, avoiding unnecessary complexity.
• Persist and restore file editing buffers, indirect buffers/clones, dired buffers, tab-bar, the Emacs frame.
• Automatically save sessions by activating the mode with easysession-save-mode to ensure that the current session is automatically saved every easysession-save-interval seconds and when emacs quits.
• Helper functions: Switch to a session (i.e., load and change the current session) with easysession-switch-to, load the Emacs editing session with easysession-load, save the Emacs editing session with easysession-save and easysession-save-as, delete the current Emacs session with easysession-delete, and rename the current Emacs session with easysession-rename.

Installation

The easysession package can be installed from MELPA by adding the following to your Emacs init file:

(use-package easysession
  :ensure t
  :custom
  (easysession-save-interval (* 10 60))
  :init
  (add-hook 'emacs-startup-hook #'easysession-load-including-geometry 98)
  (add-hook 'emacs-startup-hook #'easysession-save-mode 99))Code language: JavaScript (javascript)

Note that:

• easysession-load-including-geometry is not needed after Emacs is loaded if you do not want EasySession to move or resize the Emacs frame when switching sessions. Instead, use easysession-switch-to or easysession-load to switch to another session or reload the current session without resizing or moving the Emacs frames.
• The easysession-save-mode ensures that the current session is automatically saved every easysession-save-interval seconds and when emacs quits.
• The easysession-save-interval variable determines the interval between automatic session saves. Setting it to nil disables timer-based autosaving, causing easysession-save-mode to save only when Emacs exits.
