Python observer pattern (callback/event system). Modeled after Qt Signals & Slots (but independent of Qt)
feat: make Signal and SignalInstance Generic, support static type validation of signal connections
supports the ability to perform static type checking on signal connection signatures ```python class Thing: sig = Signal(int, str) t = Thing() @t.sig.connect def cb1() -> None: ... # OK...
picking up from #169 ... starting over since lots has changed ```python from psygnal import evented from dataclasses import dataclass, field @evented @dataclass class Foo: x: int = 1 @evented(connect_child_events=True)...
solves #261 supersedes #260 Add a keyword argument to `SignalGroupDescriptor` to specify signal aliases (if the alias is None, no signal is emitted when changing the field). The signal aliases...
This PR is carrying on what I tried to do in #291. It all works, but makes for an unappealing consequence when annotating with `ClassVar[SignalGroupDescriptor]` as described in https://github.com/pyapp-kit/psygnal/pull/291#issuecomment-1988739365 working...

It will be nice to have pytest fixture to check if the Signal was emitted. Something similar to `qtbot.wati_singal` and `qtbot.wait_signals` This will be really helpful when using tread propagation...

Playing around with a pattern to add simple validation via `Annotated` on evented dataclasses. There are *no* builtin validators. It simply allows someone to declare some simple validation prior to...
