[FeatureRequest] add wheel info subcommand

[yjqg6666]

Add wheel info [./path/to/file.whl / package name from pypi] to show wheel package metadata.

[agronholm]

I could be persuaded to add such a command to be used with local wheel files, but what would it actually show? This request is kind of light on details.

[yjqg6666]

For example, mitmproxy package, wheel info requires mitmproxy could show the "Requires-Dist:" values of the unpacked file mitmproxy-11.0.0.dist-info/METADATA via wheel unpack mitmproxy-<latest-version>-py3-none-any.whl, the metadata files should be download automatically and unpacked somewhere, or query the remote server like pypi.org if such an API could be provided. wheel info all could show all the content of the unpacked METADATA file.

[agronholm]

What is the practical use case for this? Just so you know, I'm not going to make wheel do any networking operations.

[yjqg6666]

The package manager tools for OS, like apt/yum/dnf/pkg, have the similar feature. apt/yum/pkg info .

[agronholm]

pip show <package> already does this for installed packages, and there are online tools like libraries.io that let you see the dependencies of any package on the PyPI. I'm asking what practical need you have for wheel to show this information on a wheel file that hasn't been installed?

Like check the dependencies before installing it for porting the package to BSD OS.

If no networking operations, local files are ok.

pip show will not show the version ranges of dependencies.

Submit an issue to pip project?

[agronholm]

Alright, I'll take this into consideration. But yes, it's strange that pip show doesn't show the versions, or even extras.

Meanwhile, could you draft a sample output for wheel info?

[yjqg6666]

pip show <package> already does this for installed packages, and there are online tools like libraries.io that let you see the dependencies of any package on the PyPI.

Thanks for the info.

So you just want it to dump the metadata to console as-is?

[agronholm]

And not show, for example, the wheel version or generator from WHEEL?

[yjqg6666]

$ wheel info all mitmproxy-xxx.whl

the content of the metadata file.

$ wheel info name xxx.whl
the value of the name field

$wheel info require xxx.whl

aioquic <=1.2.0,>=1.1.0;asgiref <=3.8.1,>=3.2.10;typing-extensions <=4.11.0,>=4.3 ;

[agronholm]

I think the output of pip show is much more user friendly – it just needs to have all the information and not omit the version ranges

[yjqg6666]

$ wheel info urls <pkg.whl>
