Preserve the scratch buffer across Emacs sessions
Preserve the state of scratch buffers across Emacs sessions by saving the state to and restoring it from a file, with autosaving and backups. Save scratch buffers: `persistent-scratch-save' and `persistent-scratch-save-to-file'. Restore saved state: `persistent-scratch-restore' and `persistent-scratch-restore-from-file'. To control where the state is saved, set `persistent-scratch-save-file'. What exactly is saved is determined by `persistent-scratch-what-to-save'. What buffers are considered scratch buffers is determined by `persistent-scratch-scratch-buffer-p-function'. By default, only the `*scratch*' buffer is a scratch buffer. Autosave can be enabled by turning `persistent-scratch-autosave-mode' on. Backups of old saved states are off by default, set `persistent-scratch-backup-directory' to a directory to enable them. To both enable autosave and restore the last saved state on Emacs start, add (persistent-scratch-setup-default) to the init file. This will NOT error when the save file doesn't exist. To just restore on Emacs start, it's a good idea to call `persistent-scratch-restore' inside an `ignore-errors' or `with-demoted-errors' block.
