UndoManager Fixes #25

@thecoolwinter thecoolwinter commented Feb 24, 2024

Description

  • Fixes incorrect use of grouping in replaceCharacters. Fixes an issue where every edit was grouped, disabling the ability to undo individual operations. Future work will need to be done to enable grouping undo operations for multi-cursor operations.
  • Makes undo/redo text storage operations occur in a transaction. Makes those operations appear as a single coalesced edit when sent to text storage delegates.
  • Fixes an issue where the undo manager would never group the sequence of Newline + Whitespace (eg when making a newline and then inserting a tab). Also fixes the grouping order when deleting lines, so undoing a deleted line behaves as expected.
