caenhv-client-python 0.1.0

Python interface to the caenhv-client GUI: fire/raise the application from other Python projects (e.g. labscript BLACS)

caenhv-client-python

Python interface to the caenhv-client GUI (CAEN HV control with channel linking). Zero dependencies; the GUI itself is distributed as a standalone executable.

The only capability is firing the GUI — raise its window if running, launch it otherwise — over a tiny local IPC protocol. There is deliberately no remote control of HV settings.

from caenhv_client_python import fire_gui, notify_gui

fire_gui()      # raise the window if running, otherwise launch the GUI
notify_gui()    # raise only; returns False if the GUI is not running

Configuration via environment variables:

• CAENHV_CLIENT_COMMAND — path (or command line) of the caenhv-client executable, used when it is not on PATH.
• CAENHV_CLIENT_IPC_NAME — IPC server name (default caenhv-client), must match the GUI's setting when overridden.

Works from any Python process, including labscript BLACS tabs and workers; no Qt required (a Unix-socket / named-pipe transport is used, with PyQt5 as an optional fallback).
