> The default for `--optional` flags in doctests really should be optional
packages only, so I don't want pip packages to be tested by doctests by
default. Therefore, I also don't want those packages to appear in `sage
--optional`. So I really prefer to see them as a new category: not
standard, not optional, not experimental.
I see several solutions to deal with "pip packages":
1. having a new category of packages (let say python-optional)
2. be stricter about versioning, i.e. in piprules specify the version of
the packages we support
{{{
brian=1.3.1
trac=2.3
}}}
Very simple to maintain!
I agree that it would be hard to prevent a pip package to just break
because versions are not backward compatible. So solution 2 looks
appropriate to me. Otherwise, we can have a more precise tagging system
for python-optional packages
{{{
sage: my_test() # python-optional -- 3.5 <= beautifulsoup <= 4.1.2
}}}
It is more flexible than the piprules strict versioning solution but the
cost of maintenance is much higher.
