A python library providing a useful abstraction for recording state transitions, compressing them, and distributing to multiple listeners.
The :class:Succession class provides a way to reduce long chains of updates
down to a reduced chain with the same effect.
For example, assume that you only care about the sum of the numbers pushed to a succession, and that it's fine to replace all of the numbers from before you started listening with the current total. You can do something like the following:
succession = Succession(compress=lambda items: [sum(items)]) <succession.Succession object at 0x7f5a65a10518> from_start = succession.iter() for i in [1, 2, 3, 4, 5]: ... succession.push(i) ... succession.close() from_end = succession.iter() list(from_start) [1, 2, 3, 4, 5]) list(from_end) [15]
Iterators forked earlier will not miss any transitions added from the time they were created. Compression is only applied to transitions before the fork.
Recommended method is to use the version from pypi_

pip install succession
