Brackette
A simple state manager implementing the memento design pattern and heavily based on the tutorial from refactoring.guru.
The brackette (a bracket-cassette) logo was scribbled by @PostSin on slatepacks.com marketplace for which I paid 2ツ (ツ is grin cryptocurrency) and it was best deal ever!
from brackette.memento import Originator, Caretaker
originator = Originator()
caretaker = Caretaker(originator)
originator.do_stuff('hello')
print(originator._state)
print(originator._hash)
caretaker.backup()
originator.do_stuff('meoreo')
print(originator._state)
print(originator._hash)
caretaker.backup()
originator.do_stuff('kinda')
print(originator._state)
print(originator._hash)
caretaker.backup()
caretaker.undo()
print(originator._state)
print(originator._hash)
caretaker.undo()
print(originator._state)
print(originator._hash)
caretaker.redo()
print(originator._state)
print(originator._hash)
caretaker.undo()
print(originator._state)
print(originator._hash)
caretaker.show_history()
outputs
