v0.8.0a3

What's Changed

• Windows: fix unit tests & enable CI by @Tom-Willemsen in #633
• Declarative EPICS and StandardReadable Devices by @coretl in #598

Changes

pvi structure changes

Structure read from .value now includes DeviceVector support. Requires at least PandABlocks-ioc 0.11.2

Epics signal module moves

ophyd_async.epics.signal moves to ophyd_async.epics.core with a backwards compat module that emits deprecation warning.

# old
from ophyd_async.epics.signal import epics_signal_rw
# new
from ophyd_async.epics.core import epics_signal_rw

StandardReadable wrappers change to StandardReadableFormat

StandardReadable wrappers change to enum members of StandardReadableFormat (normally imported as Format)

# old
from ophyd_async.core import ConfigSignal, HintedSignal
class MyDevice(StandardReadable):
    def __init__(self):
        self.add_readables([sig1], ConfigSignal)
        self.add_readables([sig2], HintedSignal)
        self.add_readables([sig3], HintedSignal.uncached)
# new
from ophyd_async.core import StandardReadableFormat as Format
class MyDevice(StandardReadable):
    def __init__(self):
        self.add_readables([sig1], Format.CONFIG_SIGNAL)
        self.add_readables([sig2], Format.HINTED_SIGNAL)
        self.add_readables([sig3], Format.HINTED_UNCACHED_SIGNAL

Declarative Devices are now available

# old
from ophyd_async.core import ConfigSignal, HintedSignal
from ophyd_async.epics.signal import epics_signal_r, epics_signal_rw

class Sensor(StandardReadable):
    def __init__(self, prefix: str, name="") -> None:
        with self.add_children_as_readables(HintedSignal):
            self.value = epics_signal_r(float, prefix + "Value")
        with self.add_children_as_readables(ConfigSignal):
            self.mode = epics_signal_rw(EnergyMode, prefix + "Mode")
        super().__init__(name=name)
# new
from typing import Annotated as A
from ophyd_async.core import StandardReadableFormat as Format
from ophyd_async.epics.core import EpicsDevice, PvSuffix, epics_signal_r, epics_signal_rw

class Sensor(StandardReadable, EpicsDevice):
    value: A[SignalR[float], PvSuffix("Value"), Format.HINTED_SIGNAL]
    mode: A[SignalRW[EnergyMode], PvSuffix("Mode"), Format.CONFIG_SIGNAL]
