Henrik Lissner cdbd39ba26 emacs/undo: increase undo-outer-limit 
Was missing a 0 (a typo), which meant it was less than its default
value, thus having the opposite effect and making data loss *more*
likely.

Also got rid of outdated comments; I think those have been around since
the sub-v2.0 days of Doom.

emacs/undo

Description

This module augments Emacs' built-in undo system to be more intuitive and to persist across Emacs sessions.

Maintainers

This module has no dedicated maintainers.

Module Flags

  • +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.

Plugins

Hacks

  • 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 be "silenced". i.e. It's visible in \*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.

Prerequisites

This module has no prerequisites.

TODO Features

Configuration

Disabling persistent undo history

  • 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)
