Merging 'Typing' text changes in undo stack with customized rules

Hi James,

Unfortunately no, logic deep in the undo history is just combining sequential text changes of kind Typing together.  It's not examining text characters or anything, only offsets.

Hi Actipro,

Is it possible to have this feature?

Thanks and regards,

Hi James,

This is sort of a non-standard functionality and isn't very straighforward to implement since the logic we currently have is nested deeply in the undo feature area.  All of that would need to be refactored.  I will write down the request for it, but it likely will be a lower priority item for those reasons.  How would you like to see it implemented API-wise?

Hi Actipro,

If this could be implemented, I would prefer it to be configurable to set the words. If the words are not set or null, it should work the same way as before. One possible way is to implement it as a property of the undo history.

For example:

Document.UndoHistory.WordBreakerForTyping = new List<string>() {"word1", "word2"};

Or make use of the existing rules in the word break finder in the language, but I'm not sure how this could be implemented.

I'm requesting this functionality as the new editor needs to be backward compatible with the old editor, which many existing users are familiar with.

Regards,
