codrsquad / pickley Goto Github PK

I've only skimmed the repository so forgive me if the answer is already buried somewhere but what's the recommendation for using this with multiple python versions? For example using pipenv you can specify the python version used to install the requirements, could you do such a thing as that with this?

I ask because in my team at least we actively use 2.7, 3.4 and 3.7 and it'd be good for it to know which version to be using at any given point.

Hello,
Just found pickley and I already love it 😄

I have a little question: is there (or how do I enable) completion on the CLI?
It would be handy having double-tab to complete the sub-commands (and potentially even parameters, like pickley uninstall <TAB><TAB> could list the currently installed packages)

Thanks a lot!

I'd like to be able to pickley install 'honesty[orjson]==0.3.0b1' but pickley appears to just split on == and assume the lhs is the project name.

The standard way of parsing these is:

>>> from packaging.requirements import Requirement
>>> req = Requirement("Honesty[orjson]==0.3.0b1")
>>> req.name # note that req.name is not canonicalized.
'Honesty'
>>> req.extras
{'orjson'}
>>> req.specifier
<SpecifierSet('==0.3.0b1')>
>>> str(req.specifier)
'==0.3.0b1'

>>> from packaging.version import Version
>>> list(req.specifier.filter([Version("0.2.1"), Version("0.3.0a5"), Version("0.3.0b1")]))
[<Version('0.3.0b1')>]

If you need to support legacy versions this gets only slightly harder, using packaging_legacy instead of legacy.
