where is storage of undo

[imanipourmeysam]

Hi,
I wanted to know where the information of Do/Undo mechanism is stored when we are designing.
For example, when I design something I have a list of tools and command I did during the design as you see in the picture.

I wanted to know if we can access these data or save them into a macro or something similar.
Because when we save our file and open it again, all these data of undo and redo will be removed, and we can't access them.

I need to do this for my research goal and up to now I was trying to record macro and re-execute it again, but the ideal method is to save undo/redo data and them being able to run them again even after the file is saved.
Thank you.

But it's just a list of strings. I don't know of any way to get the actual transaction history.

Yes but the thing with macro record is that you can't separate your steps properly.
if you execute the recorded macro you will go to last step instantly.

It's stored in the document -- the class name is App::Document. Internally it uses two lists of App::Transaction objects that keep the actual changes.
However, transaction are encapsulated in the document and there is no way from outside to manipulate them. All what you can get is the list of undo/redo descriptions.

No, you can't.

yes if your execute as is , but if you create one pause betwen 2 step , you modify the code as you want

just idea
