* Add `setuptools_scm` for dynamic zero-config Python versioning
This removes the need for manually bumping versions in the Python
bindings.
For the wheel uploads, the correct semver version is inferred in the case
of tagged commits, which is exactly the case in GitHub CI.
The docs were updated to reflect the changes in the release workflow.
* Add separate version variable and module, use PEP484-compliant exports
This is the best practice mentioned in the `setuptools_scm` docs, see
https://setuptools-scm.readthedocs.io/en/latest/usage/#version-at-runtime.
This behaves the same, and saves a pre-commit step. ruff just needs an
additional package location hint to correctly map first-part packages
(in this case, `google_benchmark`).
This revealed a misformat in the `google_benchmark.__init__`, which is
now fixed.
* Add pre-commit config and GitHub Actions job
Contains the following hooks:
* buildifier - for formatting and linting Bazel files.
* mypy, ruff, isort, black - for Python typechecking, import hygiene,
static analysis, and formatting.
The pylint CI job was changed to be a pre-commit CI job, where pre-commit
is bootstrapped via Python.
Pylint is currently no longer part of the
code checks, but can be re-added if requested. The reason to drop was
that it does not play nicely with pre-commit, and lots of its
functionality and responsibilities are actually covered in ruff.
* Add dev extra to pyproject.toml for development installs
* Clarify that pre-commit contains only Python and Bazel hooks
* Add one-line docstrings to Bazel modules
* Apply buildifier pre-commit fixes to Bazel files
* Apply pre-commit fixes to Python files
* Supply --profile=black to isort to prevent conflicts
* Fix nanobind build file formatting
* Add tooling configs to `pyproject.toml`
In particular, set line length 80 for all Python files.
* Reformat all Python files to line length 80, fix return type annotations
Also ignores the `tools/compare.py` and `tools/gbench/report.py` files
for mypy, since they emit a barrage of errors which we can deal with
later. The errors are mostly related to dynamic classmethod definition.
* Add Python 3.12 support tag
* Bump nanobind to latest stable v1.6.2 tag
* Add PyPI trusted publishing to GitHub workflow, add Python 3.12 wheel builds
Trusted publishing has been available since v1.8.0 of the pypa-publish
action. It enables password-less authentication and wheel uploads from
the wheel upload job.
`cibuildwheel` was bumped to v2.16.2 to allow Python 3.12 wheel builds.
More info on trusted publishing:
https://github.com/marketplace/actions/pypi-publish#trusted-publishing
The Windows distribution was reverted to `latest` in the OS matrix,
since the discovery problem of MSVC was fixed in a Bazel patch release.
* Bump nanobind to stable v1.7.0 tag
The newly created `pyproject.toml` contains all static metadata as well
as the readme and version as dynamic arguments, to be read by setuptools
during the build.
What is left in the `setup.py` for now is the custom Bazel extension
class, since that is not properly supported yet.
