cppdantic 0.0.7

Hello-world nanobind extension built against the easybind package (demo / CI smoke test)

cppdantic

Small demo that builds against the easybind package from PyPI. cppdantic and easybind are independent projects (separate repos, separate PyPI names). This repo may include external/easybind as an optional git submodule only so you can browse both trees in one checkout — it is not wired into pyproject.toml as a path dependency.

PyPI: cppdantic (when published). Versioning and tags: RELEASING.md.

Bumping easybind~=…: easybind-pin-pyproject (from easybind). Default = latest v* tag on GitHub (repo URL from that package’s PyPI metadata). Use --from-pypi for PyPI’s published latest instead — see RELEASING.md.

Build / test

You need easybind installed from PyPI (matching the pin in pyproject.toml), plus CMake ≥ 3.25, Ninja, and a C++20 compiler on PATH:

python -m pip install -U pip
python -m pip install "easybind~=0.2.14"   # align with pyproject.toml
python -m pip install -e '.[test]'
python -m pytest tests -q

CMake loads easybind/cmake/easybind_pip.cmake from the installed easybind package. PyPI must ship the cmake/ tree for the version you pin.

Optional submodule: if you use git submodule update --init external/easybind, you can also pip install -e /path/to/easybind from that checkout — it is the same easybind project, not a special cppdantic path override.

uv

From the cppdantic repo root:

uv pip install "easybind~=0.2.14"
uv pip install -e ".[test]"

(pyproject.toml sets [tool.uv] no-build-isolation-package = ["cppdantic"] so editable builds use your venv; the [test] extra pulls in setuptools-scm and scikit-build-core for that mode.)

If uv pip install fails with Metadata mismatch in METADATA (setuptools-scm version differs between build phases), clear stale artifacts and install easybind first, then cppdantic:

rm -rf build dist *.egg-info src/cppdantic/*.egg-info
uv pip install -e external/easybind/
uv pip install -e ".[test]"

Ensure src/cppdantic/_version.py is not tracked by git (it is gitignored). If it was ever committed, run git rm --cached src/cppdantic/_version.py.

Tagging

Create an annotated v* tag on main after your pins commit (see RELEASING.md).
