I don't think I've ever heard of this, much less seen it in use. And it looks like the format was approved well over two years ago, so I'm *really* surprised nothing has happened since then. That said, the dependency generator only reads egg info data about the module name and the modules it requires and translates them into RPM Provides/Requires. The other information is too unreliable to use. > Is the goal to enable installation commands like "dnf install > python3egg(Django)" and have that install the distro's Django package? > Essentially, yes. > If so, then there's some relevant work currently under way upstream to > improve the interaction between Python installation tools and build > systems to improve the metadata extraction process, rather than > relying on implementation details of setuptools. > That's great, and I hope to see something soon out of that. For a little bit of history on the pythonegg dependency generator, it was developed by Per Øyvind Karlsen for Mandriva to have more Perl-like automatic dependency generation for Python. He brought it forward and upstreamed it to RPM in August, and I made several fixes to it which were upstreamed earlier this month. Variants of this generator are in use in both Mandriva and Mageia, and I wanted to give the Python SIG in Fedora the opportunity to try it out and see if we might want to enable it in Fedora. Essentially, for things that have egg info that includes the requirements and the name of the module, it makes it simpler to figure out what how to install Python packages in a more cross-distro manner. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ python-devel mailing list python-devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/python-devel
