mkwhl - python wheel creation utility

Create Python wheel based on pyproject.toml configuration and/or provided arguments. Wheels can be created by:

• running command line tool
• pyproject.toml build backend
• calling mkwhl.create_wheel function

Goal of this project is to provide simple and minimal utility based on accepted PEPs. Usage of pyproject.toml should not be mandatory and each pyproject.toml property should be overridable by provided arguments. Functionality should not depend on specific project's repository layout. User is responsible for providing correct configuration/arguments (e.g. python/abi/platform tags) without additional "automatic" detection.

Only responsibility of mkwhl is creation of wheels. Any kind of preprocessing, including compilation of native extensions, should be done prior to mkwhl execution.

Requirements

• python >=3.10

Install

PyPI python package::

$ pip install mkwhl

Archlinux AUR::

$ yay -S mkwhl

Command line tool

Usage::

$ mkwhl --help

mkwhl will create new wheel in --build-dir (defaults to build) containing files from --src-dir (defaults to .). Files in --src-dir are selected based on --src-include and --src-exclude patterns used as pathlib.Path.glob arguments applied to --src-dir (--src-exclude patterns are prioritized over --src-include patterns). If --skip-conf is not set, project properties, which are not explicitly overridden by command line arguments, are read from --conf (defaults to pyproject.toml) as defined by project metadata_. When wheel is created, wheel name is printed to stdout (unless --quiet flag is set).

For more information::

$ man 1 mkwhl

pyproject.toml build backend

mkwhl implements build backend according to PEP517_ and PEP660_. To use mkwhl as build backend, add following to pyproject.toml::

[build-system]
requires = ["mkwhl"]
build-backend = "mkwhl"

Wheel will be build based on pyproject.toml project metadata_ and additional [tool.mkwhl] properties:

• src-dir (string)

  Source root directory. If this property is not set, existence of src_py or src directory is checked and used if available.

• license-path (string)

  Optional path to license file.

• src-include-patterns (list of strings)

  List of strings used as pathlib.Path.glob patterns applied to src_dir. These patterns specify which files should be included as part of built wheel. If not set, ['**/*'] is assumed.

• src-exclude-patterns (list of strings)

  List of strings used as pathlib.Path.glob patterns applied to src_dir. These patterns specify which files should not be included as part of built wheel. This patterns take priority over src-include-patterns. If not set, ['**/__pycache__/**/*'] is assumed.

• data-paths (list of tables)

  Optional data paths where list element is table with src and dst keys referencing source and destination path strings.

• 'python-tag' (string)

  Python tag (see binary distribution format_). If not set, py3 is assumed.

• 'abi-tag' (string)

  ABI tag (see binary distribution format_). If not set, none is assumed.

• build-tag (integer)

  Optional build tag (see binary distribution format_).

• 'platform-tag' (string)

  Python tag (see binary distribution format_). If not set, any is assumed.

• 'is-purelib' (boolean)

  Is purelib (see binary distribution format_). If not set, true is assumed.

• optional-dependencies (list of strings)

  List of strings used as keys in pyproject.toml [project.optional-dependencies]. These dependencies are required as part of build virtual environment. If not set, ['dev'] is assumed.

Python API

In addition to command line interface and build backend, package mkwhl exposes single function::

def create_wheel(src_dir: Path,
                 build_dir: Path,
                 *,
                 name: str | None = None,

                 src_exclude_patterns: typing.Iterable[str] = ['**/__pycache__/**/*'],
                 data_paths: list[tuple[Path, Path]] = [],

                 platform_tag: str = 'any',
                 is_purelib: bool = True
                 ) -> str:
    """Create wheel and return wheel name

    Argument `src_dir` is path to source root directory.

    Argument `build_dir` is path to directory where resulting wheel will be
    created.

    If one of arguments `name`, `version`, `description`, `readme_path`,
    `requires_python`, `license`, `authors`, `maintainers`, `keywords`,
    `classifiers`, `urls`, `scripts`, `gui_scripts`, `dependencies` or
    `optional_dependencies` is ``None``, associated resulting property is
    set based on project configuration read from pyproject.

    Arguments `authors` and `maintainers` are structured as list of tuples
    where first tuple element represents name and second tuple element
    represents email.

    If `conf_path` is ``None``, resulting wheel will be created based only
    on provided arguments without parsing of pyproject configuration.

    Arguments `src_include_patterns` and `src_exclude_patterns` provide
    list of strings used as `pathlib.Path.glob` patterns applied to
    `src_dir`. Include patterns specify all files that will be included in
    resulting wheel. All files specified by exclude patterns will not be
    included in resulting wheel, even if same file is specified by include
    pattern.

    Argument `data_paths` defines list of (source, destination) paths to be
    included in wheel's data directory.
