farc 0.1.0

Framework for Asyncio/Actor/AHSM Run-to-completion Concurrency

farc

Framework for Asyncio/Actor/AHSM Run-to-completion Concurrency written in Python3. In other words, a cheap knock-off of QP (www.state-machine.com) that uses coroutines instead of threads. This book describes QP and how to program hierarchical state machines.

This framework has fewer than 1000 LOC. It allows the programmer to create highly-concurrent programs by using a message-passing system and run-to-completion message handlers within a state-machine architecture. With these tools, complex, asynchronous operations are decomposed into managable chunks of code.

Known Issue: On windows, Ctrl+C is supressed by asyncio event loop's run_forever() (bug report). The workaround is to inject an event to awake the event loop.

Note: This project used to be called "pq" but that name was taken in PyPI, so I renamed to farc (ugh). If you see "pq" in the code anywhere, it means farc.
