+tree#

Uses undo-tree instead of undo-fu, which is a little less stable, but offers branching undo history and a visualizer for navigating it.

• if +tree
  • undo-tree
• else
  • undo-fu
  • undo-fu-session

• Both undo-fu and undo-tree have been modified to use zstd to compress undo history if it is available.
• undo-tree only
  • Text properties are stripped from undo history to shrink it.
  • Undo-tree is too chatty about saving its history files; this has been silenced. It will still be logged to \*Messages\*, but won’t appear in your minibuffer.
• unfo-fu only
  • Doom defines undo-fu-mode to make it easier to add hooks/mode-local keybinds.

• If you are using +tree:

  # ⎘

  (after! undo-tree
    (setq undo-tree-auto-save-history nil))
  

• If you aren’t:

  # ⎘

  (remove-hook 'undo-fu-mode-hook #'global-undo-fu-session-mode)
