Features

• Data Retrieval: Automated utilities to fetch data from varistar databases.
• Format Conversion: Seamlessly convert varistar-specific data into astropy tables or pandas DataFrames.
• Analysis Tools: Functions for processing gravitational lensing light-curves.
• Modern Workflow: Full support for uv, pip, and type-hinting for high-performance research.

Installation

Install the stable version from PyPI:

pip install varistar

Or, if you prefer using uv:

uv add varistar

Development

This project is built using the latest Python standards. If you are using this as a template or contributing:

1. Clone the repo:

   git clone https://github.com/jj-sm/varistar.git
   cd varistar

2. Sync the environment (using uv):

   uv sync

3. Run the test suite:

   uv run pytest

Releasing

Releases are cut with the Makefile, which runs lint + tests locally, bumps the version, pushes, tags, waits for the PyPI publish workflow to succeed, and only then creates the GitHub release:

make check              # ruff check + pytest (same gate as CI)
make lint                # ruff check only
make test                # pytest only
make format-check        # ruff format --check (advisory, not release-blocking)

make release VERSION=0.1.12

make release requires a clean working tree on main, up to date with origin/main. It bumps the version in pyproject.toml and src/varistar/__init__.py, commits (chore: release vX.Y.Z), pushes, tags vX.Y.Z, pushes the tag (which triggers .github/workflows/publish.yml to test and publish to PyPI), watches that workflow, and creates the GitHub release only if it succeeds — a release is never created for a version that failed to publish.

See CHANGELOG.md for release history.
