spac-kit-europa-clipper 0.2.1

CCSDS packet definitions for Europa Clipper instruments

SPaC-kit-europa-clipper

For instruments ECM, MISE and SUDA, some of the CCSDS packets definitions are coded here, as needed by the Science Data System.

Those packet definitions are used by the SPaC-kit library to decode CCSDS packets, generate documentation and simulated datasets.

Prerequisites

This package has been tested with Python 3.12.

Users

Install the main package:

pip install spac-kit

Install the plugin from pypi (NOT PUBLISHED ON PYPI YET):

pip install spac-kit-europa-clipper

You can now parse a downlink file from Europa-Clipper:

spac-parse --file {your europa-clipper file}

Small test downlink files are provided here:

Instrument	File
ECM	file
SUDA	file

Generate the documentation locally:

sphinx-autobuild ./docs/. ./docs/out

Developers

Update, Test

Clone the repository:

git clone  https://github.com/joshgarde/europa-cliper-ccsds-plugin.git

Create a virtual environment and activate it:

python -m venv venv
source venv/bin/activate   # On Windows use `venv\Scripts\activate`

You might need to upgrade pip first:

pip install --upgrade pip

Install the package in editable mode, with the developer dependencies:

pip install -e '.[dev]'

Or use poetry:

Install poetry, from your local system, not a virtual environment:

curl -sSL https://install.python-poetry.org | python3.12 -
export PATH=${HOME}/.local/bin:${PATH}

Create a poetry virtual environment and install the package with the developer dependencies:

poetry env use python3.12
poetry install --with dev

Optionally, to work with a local version of Spac-Kit, you can use poetry as follows:

poetry add ../SPaC-Kit

Beware of the version of Spac-Kit you are using, it should be compatible with the version specified in the pyproject.toml file of this package.

IMPORTANT: Install the pre-commit hooks, they will ensure code quality. If you don't do it the automated test running on the Pull Request will fail.

pre-commit install && pre-commit install -t pre-push

Make your changes in the package definition files located in the ccsds.packets.europa_clipper directory.

Create/Update the test reference data as needed, next to the updated packet definitions, for example ccsds.packets.europa_clipper.ecm.test.

Run the tests to ensure everything is working:

pytest

Before committing your changes update the poetry lock file:

poetry lock

Generate the documentation locally (e.g. for review purposes)

cd docs
poetry run sphinx-build -b html . _build/html

Open the file docs/_build/html/index.html in your browser to view the generated documentation.

Releasing

To prepare for a new release candidate PR should be created against the main branch. The branch of the release should be prefixed with release/ with the version string preceding. For example: release/1.0.0.

git checkout -b release/X.Y.Z
git push

When this branch is created, the "Publish to PyPI" GH Actions workflow will run which will automatically publish a build to the PyPI testing environment where the build can be tested with any downstream tools/services.

To create the new release, merge the PR which will kickoff the "Lint, test, and release" CI pipeline. This pipeline will perform an automatic linting and run the repo's tests. After both steps pass, the workflow will then tag the merged PR commit and create a new release off of that tag.

Once that release is created, several processes will occur:

1. The "Publish to PyPI" workflow will run again, except now it will publish to the main PyPI repository.

2. Zenodo will pickup the new release for DOI generation + archival. This process is automatic and managed by Zenodo. It is simply kicked off on our end once a new release is cut.

Once these processes are complete, a release has been successfully cut.

Citation with Zenodo

This package can be cited with a DOI provided by Zenodo.
