Detailed Description

PEP 656 support.

This module implements logic to detect if the currently running Python is
linked against musl, and what musl version is used.

Function Documentation

_get_musl_version()

Optional[_MuslVersion] pip._vendor.packaging._musllinux._get_musl_version ( str  executable )

protected

Detect currently-running musl runtime version.

This is done by checking the specified executable's dynamic linking
information, and invoking the loader to parse its output for a version
string. If the loader is musl, the output would be something like::

    musl libc (x86_64)
    Version 1.2.2
    Dynamic Program Loader

_parse_ld_musl_from_elf()

Optional[str] pip._vendor.packaging._musllinux._parse_ld_musl_from_elf ( IO[bytes]  f )

protected

Detect musl libc location by parsing the Python executable.

platform_tags()

Iterator[str] pip._vendor.packaging._musllinux.platform_tags

(

str

arch

)

Generate musllinux tags compatible to the current platform.

:param arch: Should be the part of platform tag after the ``linux_``
    prefix, e.g. ``x86_64``. The ``linux_`` prefix is assumed as a
    prerequisite for the current platform to be musllinux-compatible.

:returns: An iterator of compatible musllinux tags.
