wheel-filename lets you verify wheel <https://www.python.org/dev/peps/pep-0427/>_ filenames and parse them into their component fields.

This package adheres strictly to the relevant PEPs, with the following exceptions:

• Unlike other filename components, version components may contain the characters ! and + for full PEP 440 support.

• Version components may be any sequence of the relevant set of characters; they are not verified for PEP 440 compliance.

• The .whl file extension is matched case-insensitively.

Installation

wheel-filename requires Python 3.6 or higher. Just use pip <https://pip.pypa.io>_ for Python 3 (You have pip, right?) to install wheel-filename::

python3 -m pip install wheel-filename

Example

from wheel_filename import parse_wheel_filename pwf = parse_wheel_filename('pip-18.0-py2.py3-none-any.whl') str(pwf) 'pip-18.0-py2.py3-none-any.whl' pwf.project 'pip' pwf.version '18.0' pwf.build is None True pwf.python_tags ['py2', 'py3'] pwf.abi_tags ['none'] pwf.platform_tags ['any'] list(pwf.tag_triples()) ['py2-none-any', 'py3-none-any']

API

parse_wheel_filename(filename) Parses a wheel filename (a str, bytes, or os.PathLike) and returns a ParsedWheelFilename instance. Any leading directory components are stripped from the argument before processing. If the filename is not a valid wheel filename, raises an InvalidFilenameError.

ParsedWheelFilename A namedtuple representing the components of a wheel filename. It has the following attributes and methods:

project: str The name of the project distributed by the wheel

version: str The version of the project distributed by the wheel

build: Optional[str] The wheel's build tag (None if not defined)

python_tags: List[str] A list of Python tags for the wheel

abi_tags: List[str] A list of ABI tags for the wheel

platform_tags: List[str] A list of platform tags for the wheel

str(pwf) Stringifying a ParsedWheelFilename returns the original filename

tag_triples() -> Iterator[str] Returns an iterator of all simple tag triples formed from the compatibility tags in the filename

InvalidFilenameError A subclass of ValueError raised when an invalid wheel filename is passed to parse_wheel_filename(). It has a filename attribute containing the basename of the invalid filename.

Command

New in version 1.4.0

wheel-filename also provides a command of the same name that takes a wheel filename (The actual wheel does not have to exist) and outputs the filename components as JSON.

Example::

$ wheel-filename pip-18.0-py2.py3-none-any.whl
{
    "project": "pip",
    "version": "18.0",
    "build": null,
    "python_tags": [
        "py2",
        "py3"
    ],
    "abi_tags": [
        "none"
    ],
    "platform_tags": [
        "any"
    ]
}
