📦 About this repository

horiba-sdk is a package that provides source code for the development of custom applications that include interaction with Horiba devices, namely monochromators and multichannel detectors (e.g. CCD cameras). Future versions of this package will include access to more devices. The SDK exists for several programming languages:

• Python (this repo)
• C#
• C++
• LabVIEW

☑️ Prerequisites

To use this package, the following conditions must be met:

• Python >=3.9 is installed

• ICL.exe installed as part of the Horiba SDK, licensed and activated. The Horiba SDK can be purchased by contacting the Horiba Support and sending a message to the Scientific business segment, specifying no division and selecting the sales department

• To make sure that the USB devices do not get disconnected, uncheck the following boxes in the properties

  

🛠️ Getting Started

Video of the steps below

1. (Optional but recommended) Work in a virtual environment:

   Navigate to the (empty) project folder you want to work and run:

   python -m venv .
   

   Activate the virtual environment:

   Windows

   .\Scripts\activate
   

   Unix

   source ./bin/activate
   

   Note: do deactivate it, simply run deactivate.

2. Install the sdk:

   pip install horiba-sdk
   

   or install with Poetry

   poetry add horiba-sdk
   

3. Create a file named center_scan.py and copy-paste the content of examples/asynchronous_examples/center_scan.py

4. Install the required library for plotting the graph in the example:

   pip install matplotlib
   

   or install with Poetry

   poetry add matplotlib
   

5. Run the example with:

   python center_scan.py
   

🔗 Examples

Getting Started

The files in the folder examples/asynchronous_examples/ can be used as a starting point for a custom application.

Tests

The files in the folder tests/test_single_devices can be used to explore further functionality.

Asynchronous vs Synchronous Examples

This SDK is based on Websocket communication. The nature of this communication is asynchronous by its design. The way this SDK uses websockets is to send requests to the underlying instrument control layer (ICL) and get a (nearly immediate) reply back. This is true even for commands that longer to execute, e.g. to move the mono or to acquire data from the CCD. The way this is handled is by sending an acknowledgement back that the command is received and being processed. The user has then to inquire if mono_isBusy to see when the hardware is free to receive the next command. That means that every async function can be awaited immediately and handled just like any other function. To learn more about async and await, check out this introduction or take a deeper dive here.

🏗️ Architecture

The functionality is distributed over two parts, the instrument control layer (ICL) and the github source code. This split is shown in the following image:

The ICL itself is sold and distributed by Horiba. The source code to communicate with the ICL and drive the instruments is located in this repo for Python, but can be also found for C#, C++ and LabVIEW as described above. The communication between SDK and ICL is websocket based. I.e. in essence the ICL is steered by a command and control pattern where commands and their replies are JSON commands.

👩‍💻 First steps as contributor

Clone and set up the repo

1. Clone the repo:

git clone https://github.com/HORIBAEzSpecSDK/horiba-python-sdk.git
cd horiba-python-sdk

2. If you don't have Poetry installed run:

make poetry-download

3. Initialize poetry and install pre-commit hooks:

make install
make pre-commit-install

4. Run the codestyle:

make codestyle

5. To push local changes to the remote repository, run:

git add .
git commit -m "feat: add new feature xyz"
git push

Poetry

Want to know more about Poetry? Check its documentation.

Details about Poetry

Poetry's commands are very intuitive and easy to learn, like:

• poetry add numpy@latest
• poetry run pytest
• poetry publish --build

etc

Building and releasing your package

Building a new version of the application contains steps:

• Bump the version of your package poetry version <version>. You can pass the new version explicitly, or a rule such as major, minor, or patch. For more details, refer to the Semantic Versions standard.

• Update the CHANGELOG.md with git-changelog -B auto -Tio CHANGELOG.md

• Make a commit to GitHub.

• Create a tag and push it. The release is automatically triggered on tag push:

  git tag vX.Y.Z # where the version MUST match the one you indicated before
  git push --tags
  

Makefile usage

Makefile contains a lot of functions for faster development.

1. Installation of Poetry

To download and install Poetry run:

make poetry-download

To uninstall

make poetry-remove

2. Install all dependencies and pre-commit hooks

Install requirements:

make install

Pre-commit hooks could be installed after git init via

make pre-commit-install

3. Codestyle

Automatic formatting uses pyupgrade, isort and black.

make codestyle

# or use synonym
make formatting

Codestyle checks only, without rewriting files:

make check-codestyle

Note: check-codestyle uses isort, black and darglint library

Update all dev libraries to the latest version using one comand

make update-dev-deps

4. Code security

make check-safety

This command launches Poetry integrity checks as well as identifies security issues with Safety and Bandit.

make check-safety

5. Type checks

Run mypy static type checker

make mypy

6. Tests with coverage badges

Run pytest

Unix:

make test

Windows:

poetry run pytest -c pyproject.toml --cov-report=html --cov=horiba_sdk tests/

For the hardware tests run the following:

Windows:

$env:HAS_HARDWARE="true"
# If you want a remote ICL be used for the tests
# $env:TEST_ICL_IP="192.168.21.24"
# $env:TEST_ICL_PORT="1234"
poetry run pytest -c pyproject.toml --cov-report=html --cov=horiba_sdk tests/

Unix:

HAS_HARDWARE="true"
# If you want a remote ICL be used for the tests
# TEST_ICL_IP="192.168.21.24"
# TEST_ICL_PORT="1234"
make test

7. All linters

Of course there is a command to rule run all linters in one:

make lint

the same as:

make test
make check-codestyle
make mypy
make check-safety

8. Docker

make docker-build

which is equivalent to:

make docker-build VERSION=latest

Remove docker image with

make docker-remove

More information about docker.

9. Cleanup

Delete pycache files

make pycache-remove

Remove package build

make build-remove

Delete .DS_STORE files

make dsstore-remove

Remove .mypycache

make mypycache-remove

Or to remove all above run:

make cleanup

📚 Documentation

The latest documentation can be found at horiba-python-sdk.readthedocs.io. In order to build it locally, run the following in the docs/ folder:

make html

The documentation will then be built under docs/build/html/.

Documentation is built each time a commit is pushed on main or for pull requests. When release tags are created in the repo, readthedocs will also tag the documentation accordingly
