I think bdist_wheel should probably accept a setup() argument to set the tags. Currently you can just set a "universal" flag which means pure 2+3 python.

There’s also —plat-name argument for the setuptools command, but that doesn’t work. I’d have to rename the platform tag from “any” to a list of supported platforms, is that correct? That would give a pretty convoluted filename, because the platform tag doesn’t allow for wildcards. That is, there is no way to specify “any linux”, only something like “linux_x86_64” (to borrow a tag from PEP 425). Ronald

Hi,

Is there a way to create a wheel that contains only python code, but can only be installed on particular platforms?

In particular, I'm looking for a way to create a wheel for py2app that can only be installed on OSX because py2app cannot "cross-compile" application bundles.

My position has been that if there is no alternative that works on a different platform, then at least the wheel metadata should say nothing. It's only there to allow the installer to pick among the best of several alternatives.

The py2app setup.py file currently hardcodes a platform check because users did install py2app on other platforms (mostly Windows) and then complained that it didn’t work. It is much nicer to tell the user that a package won’t work during installation. Ronald

You are probably a perfect customer for supports_environment

It occurs to me that if we split the hooks stuff out of PEP 359, we'd be pretty close to a releasable metadata 2.0 spec... Cheers, Nick.

Perhaps not yet, but the idea is there in the 'supports_environments' metadata in PEP 426. This is currently supported by distil, but I don't believe pip does yet.

supports_environment would work for me. Ronald
