I have to integrate the undo/redo functionality of text% into a custom undo/redo system, because in my application nearly everything is undoable.
Basically I need a reliable way to intercept and track the text%'s undo additions, so I can add an undoer to my undo system whenever text% adds an internal undoer. But how? If I understand this correctly, on-change tracks *all* changes character by character, but the automatic undo handling pushes one undoer for several edit operations on the undo stack as it should. I can't find a method for tracker the internal undoer in text% that can be augmented or overriden. Something like on-undo-add. Am I missing something?
