refkit-core

refkit-core is the native Rust/PyO3 package used by refkit. It exposes the extension module refkit_core._refkit_core and the Python import package refkit_core.

Most projects should install refkit:

pip install refkit

refkit pins one exact refkit-core version and checks that version at import time. Direct refkit_core imports are supported for native integration tests, packaging smoke tests, and low-level embedding.

import refkit_core

library = refkit_core.Library.parse_bibtex(
    """
@article{doe2024,
  author = {Doe, Jane},
  title = {Fast Citations},
  journal = {Journal of Citation Tests},
  year = {2024}
}
"""
)
document = refkit_core.Document(library, refkit_core.Style.load("apa"), locale="en-US")
rendered = document.render([refkit_core.Citation("intro", "doe2024")])

print(rendered["intro"].text)

Expected output:

(Doe, 2024)

tidy_bibtex formats BibTeX text through the same native package:

result = refkit_core.tidy_bibtex(
    "@ARTICLE{doe2024, pages={6-13}, year={2024}}\n",
    options=refkit_core.TidyOptions(sort_fields=True),
)

print(result.bibtex)

Package Contract

refkit-core owns the native implementation for:

Use refkit for one-call path helpers such as refkit.cite and refkit.full_bibliography.

Pyodide

Pyodide uses the same native extension package as CPython. The release workflow builds refkit-core for wasm32-unknown-emscripten with toolchain values from pyodide config get, then publishes the PyEmscripten wheel alongside the CPython wheels. The pure Python refkit package keeps the same exact dependency on refkit-core, so Pyodide resolves the matching wheel from PyPI. The Pyodide lane takes the Python target and PyEmscripten ABI from the release workflow.

Development

uv sync --all-packages --group dev
(cd packages/refkit-core && uv run maturin develop)
uv run pytest packages/refkit/tests --no-cov

Build only the native package:

uv build --package refkit-core --no-create-gitignore
