liblaf-nox-recipes keeps noxfile.py sessions small by packaging the uv, pytest, and CUDA glue you would otherwise repeat across repositories.

✨ Features

• 💨 Bootstrap uv-managed environments in one call: setup_uv() compiles constraints from pyproject.toml, resolves the dependency groups you ask for, syncs the session environment, and installs the current project in editable mode.
• 📉 Exercise multiple dependency strategies: Resolution exposes highest, lowest, and lowest-direct modes so you can cover both everyday development and lower-bound compatibility in CI.
• 🧪 Keep test sessions short without hiding pytest: pytest() forwards s.posargs, supports per-session environment variables, and keeps shared flags out of each @nox.session.
• ⚡ Run CodSpeed-friendly benchmarks: pytest_bench() adds the benchmark marker, --codspeed, and single-process defaults when helpers like pytest-xdist are installed.
• 🖥️ Skip GPU-only jobs safely: supports_cuda() and cuda_driver_version() use NVML to decide whether CUDA-specific sessions should run.

📦 Installation

[!NOTE] liblaf-nox-recipes requires Python 3.12+ and expects uv to be available anywhere your nox sessions run.

uv add --dev liblaf-nox-recipes

If you also want uv to create and manage the virtual environments that nox uses, install nox-uv and set nox.options.default_venv_backend = "uv" in your noxfile.py.

🚀 Quick Start

from typing import Any

import nox

from liblaf import nox_recipes as recipes
from liblaf.nox_recipes import Resolution

nox.options.default_venv_backend = "uv"
nox.options.reuse_existing_virtualenvs = True

PYPROJECT: dict[str, Any] = nox.project.load_toml("pyproject.toml")
PYTHON_VERSIONS: list[str] = nox.project.python_versions(PYPROJECT)


@nox.session(python=PYTHON_VERSIONS, reuse_venv=True, tags=["test"])
@nox.parametrize(
    "resolution",
    [
        nox.param(Resolution.HIGHEST, id="highest"),
        nox.param(Resolution.LOWEST_DIRECT, id="lowest-direct"),
    ],
)
def test(s: nox.Session, resolution: Resolution) -> None:
    recipes.setup_uv(s, groups=["test"], resolution=resolution)
    recipes.pytest(s, suppress_no_test_exit_code=True)

Start with setup_uv() for the common case. When you need finer control, drop down to uv_pip_compile(), uv_pip_sync(), and uv_pip_install() directly. For GPU-only jobs, guard the session with supports_cuda() before doing any CUDA-dependent work.

⌨️ Local Development

git clone https://github.com/liblaf/nox-recipes.git
cd nox-recipes
mise run install
nox
mise run docs:serve

nox executes the test-tagged matrix from noxfile.py, and mise run docs:serve rebuilds the docs site that also embeds this README.

🤝 Contributing

Focused issues and pull requests are welcome. Please run nox before opening a PR, and rebuild the docs with mise run docs:serve when you change documentation or public APIs.
