More flexibility about tags when shipping binaries

Currently there are a few situations that I would like to generate tags for but I can't.

In particular I have the following setups I care about:

• 2.x/3.x universal wheels that ship native extensions not linked against libpython and thus python version independent
• 2.x or 3.x specific wheels without abi identifier because not linking against libpython

This is from what I can tell not possible without monkey patching. Currently I'm doing this:

if bdist_wheel is not None:
    class CustomBdistWheel(bdist_wheel):
        def get_tag(self):
            rv = bdist_wheel.get_tag(self)
            return ('py2.py3', 'none') + rv[2:]
    cmdclass['bdist_wheel'] = CustomBdistWheel

I was thinking of sending a pull request but I'm not sure what the cleanest way to solve this is.

In the past I've just added a flag, like the universal flag and the new py_limited_api flag. Then bdist_wheel has logic to set the flag for that category of wheel. Here's the pull request that added the py_limited_api flag.

Looks like a duplicate of #161 yes?

I feel this issue should be dealt with one way or another before the 1.0.0 release.

Given the --plat-tag option, it seems like the natural extension would be to also offer --abi-tag and --version-tag.

All 3 could accept the :default: special value suggested in #153 (comment) to request the standard behaviour of inferring them from the running Python.

(This could prove especially useful in combination with the new wheel pack command, since it opens the door to cross-compilation of wheel archives, where the currently running version of Python may have nothing to do with the version of Python being targeted)

Closing as not relevant to this project anymore as bdist_wheel is now canonically part of setuptools. Also, wheel tag can be used to manipulate the tags as needed afterwards.
