pep425tags no longer available -

[alexsavulescu]

Hello,

We've been relying on pep425tags to set MACOSX_DEPLOYMENT_TARGET:

    from wheel import pep425tags
    py_osx_framework = pep425tags.extract_macosx_min_system_version(sys.executable)
    if py_osx_framework is None:
        py_osx_framework=[10, 9]
    if py_osx_framework[1] > 9:
        log.warn("[ WARNING ] You are building a wheel with a Python built "
              "for a recent MACOS version (from brew?). Your wheel won't be portable.\n"
              "          Consider using an official Python build from python.org")
    macos_target = "%d.%d" % tuple(py_osx_framework[:2])
    log.info("Setting MACOSX_DEPLOYMENT_TARGET=%s", macos_target)
    os.environ['MACOSX_DEPLOYMENT_TARGET'] = macos_target

Since that is not available anymore, what would be the official way of achieving the above?

Thank you

If you're looking for a library API, you should be using the packaging library - that has a tags module.

Does this work? import sysconfig; sysconfig.get_var('MACOSX_DEPLOYMENT_TARGET')

This function was never part of any public API. The Wheel README plainly states that there is none:

It should be noted that wheel is not intended to be used as a library, and
as such there is no stable, public API.

This will change with v1.0 but I don't think that function will be part of the API even then. I would like to see it migrate to the packaging.tags module or similar though.

Thank you for the insight @agronholm, very clear.

@pfmoore, @mattip thanks for your help, will check those out.
