xbudget: easy handling of budgets diagnosed from General Circulation Models with xarray

Quick Start Guide

For users: minimal installation within an existing environment

conda install -c conda-forge xbudget

For developers: installing from scratch using conda

git clone git@github.com:hdrake/xbudget.git
cd xbudget
conda env create -f docs/environment.yml
conda activate docs_env_xbudget
pip install -e .
python -m ipykernel install --user --name docs_env_xbudget --display-name "docs_env_xbudget"
jupyter-lab

Releasing

The git tag is the version. xbudget has no version string checked into the source tree: hatch-vcs derives it from the tag at build time and writes xbudget/_version.py (gitignored, but shipped inside the sdist and wheel). To cut a release you tag; there is no file to bump and nothing to keep in sync.

1. Make sure main is green and has everything you want in the release, and move the ## Unreleased entries in CHANGELOG.md under the new version heading.
2. Publish a GitHub Release whose tag is vX.Y.Z, targeting the commit you want to ship:

   gh release create vX.Y.Z --target "$(git rev-parse origin/main)" \
     --title vX.Y.Z --generate-notes

   Publishing it (not merely pushing a tag) is what fires the workflow. Target the commit you actually want: a tag placed before the commit you meant to release builds the previous version, and PyPI rejects it as a duplicate.
3. The Publish to PyPI workflow builds from that tag and uploads. It checks out with fetch-depth: 0 so the tag is visible to hatch-vcs, and asserts that the built version matches the tag before publishing.
4. Verify: https://pypi.org/project/xbudget/.
5. conda-forge builds from the PyPI sdist and lags by design; the autotick bot opens the version-bump PR. The feedstock recipe must list hatch-vcs alongside hatchling in its host requirements, since it builds with --no-build-isolation.
