sharedbox
sharedbox keeps records in shared memory. Each box is one named segment, and every process that opens it reads and writes the same fields.
Installation
It is recommended to install sharedbox in a virtual environment; for example using uv:
uv venv --python 3.11
.venv\Scripts\activate
uv pip install sharedbox
Quick start
import multiprocessing as mp
from typing import Annotated
from sharedbox import Capacity, SharedBox
class Motor(SharedBox):
position: int
enabled: bool
label: Annotated[str, Capacity(32)]
def worker() -> None:
motor = Motor.attach() # finds the box by its class
motor.position = 10
motor.close()
if __name__ == "__main__":
with Motor(1, False, "x-axis") as motor:
motor.events.position.connect(lambda new, old: print(old, "->", new))
child = mp.Process(target=worker)
child.start()
child.join() # prints: 1 -> 10
Motor.unlink()
Documentation
The documentation site has a tutorial, how-to guides, explanations of how a box works, and the API reference.
C++ and C code can take a box from Python or open one by name; see the C and C++ guides.
