transponder

State broadcasting for Python. Keep a state dict and emit snapshots to registered listeners whenever it changes — a minimal observer for live status.

Install

pip install transponder

Usage

from transponder import Transponder

seen = []
t = Transponder({"alt": 0})
t.subscribe(lambda s: seen.append(dict(s)))
t.update(alt=1000, squawk="1200")
assert seen[-1]["alt"] == 1000
assert t.state["squawk"] == "1200"

Roadmap

This is an early 0.1.0 release with active development planned:

  • Filtered subscriptions by key
  • Async listeners
  • Wire-format codecs for network broadcast
