Lightweight beamline control system

Project description Documentation Status

Concert is a light-weight control system interface to control Tango and native devices. It requires Python >= 3.7, for tests you will need >= 3.8. It can be used as a library:

from concert.quantities import q
from concert.devices.motors.dummy import LinearMotor

motor = await LinearMotor()
await motor.set_position(10 *
await motor.move(-5 *

or from a session and within an integrated IPython shell:

$ concert start

concert > from concert.devices.motors.dummy import LinearMotor
concert > motor = await LinearMotor()
concert > await motor.set_position(10 *   # The asyncio blocking way
concert > task = motor.set_position(10 *  # The asyncio non-blocking way
concert > motor.position = 10 *            # User convenience for blocking calls
concert > motor.position
10 <Unit('millimeter')>

You can read more about Concert in the official documentation.
