wheel-filename lets you verify wheel filenames and parse them into their component fields.

This package adheres strictly to the standard, with the following exceptions:

• 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.

wheel-filename requires Python 3.10 or higher. Just use pip for Python 3 (You have pip, right?) to install it:

python3 -m pip install wheel-filename

>>> from wheel_filename import WheelFilename
>>> pwf = WheelFilename.parse('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']

WheelFilename

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

WheelFilename.parse(filename)

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

project: str

The name of the project distributed by the wheel

version: str

The version of the project distributed by the wheel

build: str | None

The wheel's build tag (None if not defined)

build_tuple: tuple[int, str] | tuple[()]

The build tag as a tuple for use in sorting. If build is non-None, this is (build_leading, build_trailing); otherwise, it is the empty tuple.

build_leading: int | None

If build is non-None, this is the leading integer portion of the build tag converted to an int; otherwise it is None

build_trailing: str | None

If build is non-None, this is the part after the leading integer portion of the build tag; otherwise it is None

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 WheelFilename returns the original filename

tag_triples() -> Iterator[str]

Returns an iterator of all simple tag triples formed from the compatibility tags in the filename

ParseError

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

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"
    ]
}
