ChangeLog

2.1.0 - 2022-02-07

Changed

  • Repeat and Forever no longer use ApplyM internally. This was non-intuitive, and overall decreased usability. Now Repeat and Forever always send the same arguments (if any) to their enclosed Wire.

  • RepeatM and ForeverM perform wire repetition with argument passing.

Fixed

  • Repeat called its embedded function with incorrect arguments. This has been fixed.

2.0.0 - 2022-02-06

This release adds a killer feature -- wires can return values that are passed on to the next wire. To use it, a wire returns a tuple (newWire, [arg1, arg2, ...]). Then the EventLoop will call await newWire(ev, arg1, arg2, ...).

This is backwards-compatible with the older, simpler version. We also add two new wire types, Sequence, and ApplyM. These express composition of wires two different ways. The first is created with syntax (wire1 >> wire2). It throws away the return values of wire1 and always calls wire2(ev). The second is created with Haskell syntax, wire1 >= wire2. It passes the return value of wire1 into wire2's call. For example, if wire1 returns (None, [a, ...]), then wire2 is called as wire2(ev, a, ...).

Added

  • Sequence and ApplyM classes

Changed

  • Wire-s can now be called with more arguments than just the event loop. Accessing this feature requires using a 2-element return tuple, or a Repeat, Forever, or ApplyM wire.

  • Poller now raises an IndexError (instead of an AssertionError) if a duplicate socket is registered.

Fixed

  • Forever was moved into __init__ so it can be imported directly as aiowire.Forever.

1.1.0 - 2022-02-02

Added

  • See README for a complete description of aiowire's basic functionality.

Fixed

  • Fixed ZMQ dependency name to pyzmq.
