Ophyd Device definitions for LCLS Beamline components

Project description

PCDS Devices

Collection of Ophyd Device subclasses for IOCs unique to PCDS

MotivationInstallation

Motivation

Ophyd presents a uniform set of abstractions for EPICS devices. Many devices at the LCLS are covered by ophyd-provided classes such as EpicsMotor and AreaDetector, but there are also many more custom and unique devices.

This repository:

  • Defines unique device classes required by the LCLS, referenced by happi and our device_config database.
  • Offers LCLS-tailored solutions for functionality not provided by ophyd
  • Provides essential tools to aid in the creation of new devices for specific applications
  • Acts as a proving ground for features that may eventually be destined for ophyd
  • ... and more!

Much of the core re-used functionality can be found in pcdsdevices.device, pcdsdevices.interface, pcdsdevices.pseudopos, and pcdsdevices.signal.

Installation

Install the most recent tagged build:

$ conda install -c conda-forge pcdsdevices

Install the most recent development build:

$ conda install pcdsdevices -c pcds-dev -c lightsource2-tag -c conda-forge

Or alternatively:

# Install the tagged version for the dependencies
$ conda install -c conda-forge pcdsdevices

# Clone the master branch:
$ git clone https://github.com/pcdshub/pcdsdevices
$ cd pcdsdevices

# And perform a development install:
$ python -m pip install -e .

Testing

Testing from psbuild-rhel7

Use the pcds conda environment:

$ source /cds/group/pcds/pyps/conda/pcds_conda

Testing without PCDS servers

Ensure you have all of the development requirements available:

$ pip install -r dev-requirements.txt

General testing steps

$ git clone https://github.com/pcdshub/pcdsdevices
$ cd pcdsdevices

# Switch to a branch that reflects what you're working on:
$ git checkout -b my_feature_branch_name

# Make your changes to files
# Install pre-commit to allow for style checks before committing
$ pre-commit install

# Run the test suite
$ python run_tests.py -v

If all is well, commit and push your changes.

If pre-commit complains about an issue, you will need to resolve it and try again.

$ git commit -a -m "ENH: my new feature"
$ git remote add my_remote git@github.com:my_username/pcdsdevices
$ git push -u my_remote my_feature_branch_name
