Easily allow package authors to tell PyPI "my releases are hosted <here>" and have that advertised in such a way that tools can clearly communicate it to users, without silently introducing unexpected dependencies on third party services.
I haven’t read the PEP, so this might be a stupid remark, but: is that needed, when a package author can also say something like “add my repository to your system with pip —add-repository <url>” ?
The logic is that if I say
pip install foo
and foo is not hosted on PyPI, I get an error saying "cannot find foo". The quoted point is saying that we want a way for the author of foo to add metadata to PyPI that lets pip give a more helpful message:
pip install foo ERROR: No downloads for package 'foo' found. foo is hosted at the following repositoties: Main repository - http://foo.example.com/simple/ Windows wheels - http://wheels.foo.example.com/simple/ Use --index-url to specify the repository you wish to use.
(Or something like that…)
Yes, the comments in particular were inspired by Egenix’s own repositories. I saw that they had different repositories for UCS2 and UCS4 and I thought that it would be awesome if pip could tell end users about both of those and give hem the information to choose between which ones were relevant. In this way it supports more things than the existing mechanisms support because the old things don’t allow any mechanism for selective addition which means binary distributions are hard if the filename doesn’t include enough information for pip/easy_install to actually select the proper download and you have to encode some of that information in the URL. --- Donald Stufft PGP: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
