Utility functions for use within the Project PANOPTES ecosystem and for general astronomical processing.

This library defines a number of modules that contain useful functions as well as a few services.

To install type:

pip install panoptes-utils

Full options for install:

pip install "panoptes-utils[config,docs,images,testing,social]"

See the full documentation at: https://panoptes-utils.readthedocs.io

There are a few system dependencies depending on what functionality you will be using.

In particular, the plate solving requires astrometry.net and the appropriate index files.

Use the following on a debian-based system (e.g. Ubuntu) to easily install all dependencies:

apt-get update && apt-get install --no-install-recommends --yes \
  libffi-dev libssl-dev \
  astrometry.net astrometry-data-tycho2 \
  dcraw exiftool libcfitsio-dev libcfitsio-bin \
  libfreetype6-dev libpng-dev libjpeg-dev libffi-dev

The panoptes-utils command line tool is available for use with subcommands corresponding to the modules in this library. Currently, the only implemented subcommand is image, which includes commands for converting cr2 files into jpg and/or fits files as well as for plate-solving fits images.

The panoptes-utils image watch <path> command will watch the given path for new files and convert them to jpg and/or fits files as they are added.

See panoptes-utils --help and panoptes-utils image --help for details.

There is a simple key-value configuration server available as part of the module.

After installing with the config option as above, type:

panoptes-config-server run --config-file <path-to-file.yaml>

This project uses UV for fast Python package and environment management with modern PEP 735 dependency groups.

Prerequisites:

• Python 3.12+
• UV: https://docs.astral.sh/uv/ (install via curl -LsSf https://astral.sh/uv/install.sh | sh or pipx install uv).

Basic workflow:

• Create and sync a dev environment with all dependencies:

  # Install all optional extras and dev dependencies (recommended for development)
  uv sync --all-extras --group dev
  
  # Or install only base dependencies
  uv sync
  
  # Activate the virtual environment
  source .venv/bin/activate
  # or run commands without activating using `uv run ...`

• Install specific dependency groups as needed:

  # Install testing dependencies
  uv sync --group testing
  
  # Install linting tools
  uv sync --group lint
  
  # Install all dev dependencies (includes testing + lint)
  uv sync --group dev

• Install specific optional extras as needed (choose any):

  # Examples: config, images, docs, examples
  uv sync --extra config --extra images --extra docs
  
  # Or install all extras
  uv sync --all-extras

• Run tests:

  # All tests with coverage, using pytest options from pyproject.toml
  uv run pytest
  
  # Single test file
  uv run pytest tests/test_utils.py

• Lint / style checks:

  # Lint with Ruff
  uv run ruff check .
  
  # Auto-fix linting issues
  uv run ruff check --fix .
  
  # Format code with Ruff
  uv run ruff format .
  
  # Check formatting without making changes
  uv run ruff format --check .

• Build the package (wheel and sdist):

  uv build

• Run the CLI locally (Typer app):

  uv run panoptes-utils --help

• Versioning: Version is derived from git tags via setuptools-scm. To produce a new version, create and push a tag (e.g., v0.1.0).

To test the software, prefer running via UV so the right environment and options are used:

uv run pytest

By default all tests will be run. If you want to run one specific test, give the specific filename as an argument to pytest:

uv run pytest tests/test_mount.py
