t4racker
Transparent time-travel tracker for Python objects. Records mutations to dicts, sets, lists, and custom objects—then replay state at any step.
Install
pip install t4racker
Usage
from t4racker import TTTTracker, TrackReplayer
class Algorithm:
def __init__(self):
self.visited = set()
self.path = []
tracker = TTTTracker()
algo = Algorithm()
tracker.track(algo, tracked_fields=['visited', 'path'])
tracker.capture_snapshot('start')
algo.visited.add('A')
algo.path.append('A')
algo.visited.add('B')
algo.path.append('B')
# Export
data = tracker.to_dict()
# Replay
replayer = TrackReplayer(data)
state = replayer.state_at(2) # State after step 2
print(state) # {'visited': {'A', 'B'}, 'path': ['A']}
What it tracks
- dict:
__setitem__,__delitem__ - set:
