This release is a pre-release and may not be stable for production use.
PlestyLib
PlestyLib is the core Python library in the PLESTY ecosystem for building standardized device APIs for laboratory and experimental automation.
It provides reusable abstractions for:
- Device lifecycle and synchronous device models
- Transport/traffic management (Serial, VISA, TCP/IP)
- Command and operation solvers (for example SCPI and operation-message protocols)
- Parameter and function metadata systems
- Auto testing helpers, logging, and error-handling utilities
Requirements
- Python 3.12+
Installation
Install from package index:
pip install plesty-lib
# or
uv add plesty-lib
Optional dependencies
Features that need a heavy or platform-specific package keep it out of the
base install and behind an extra. Without the extra the feature raises an
ImportError naming it; nothing else is affected.
| Extra | Adds | Enables |
|---|---|---|
hdf5 |
h5py |
convert_to_hdf5 — packs saved results into one HDF5 archive |
pip install "plesty-lib[hdf5]"
# or
uv add "plesty-lib[hdf5]"
For development, install from source and sync the dev dependency group:
uv sync --group dev
# or
pip install -e .
pip install plesty-sdk
Quick Start
1. Create a device class from a base device
from plesty.lib.device.base_visa_scpi_device import BaseVisaScpiDevice
class PowermeterDevice(BaseVisaScpiDevice):
def __init__(self, address: str):
super().__init__(address)
self.register_config("POWER", dtype=float, read_only=True, command="MEAS:SCAL:POW")
self.register_config("WAVELENGTH", dtype=int, unit="nm", command="SENS:CORR:WAV")
2. Use the device
# replace the serial number P0000001 with that of your own device
address = "USB0::0x1313::0x8078::P0000001::INSTR"
with PowermeterDevice(address) as dev:
print(dev.identity())
print(dev.query("POWER"))
Architecture Overview
PlestyLib encourages a layered device API design:
- Base device model: operation entry points and parameter/function systems
- Command/operation solver: map standardized calls to protocol payloads
- Traffic manager: transport-specific I/O with real hardware
- Optional wrappers: async and TCP/IP service/client patterns
This separation keeps implementations testable and easier to maintain.
