Does this resolve environment markers?

Hey @uranusjr! Sorry for the delay in a response.

Life did its thing and then I got engaged toward getting pip 10 ready for release.

Essentially, the resolution algorithm doesn't see environment markers. All the resolver sees are requirements and candidates for those requirements. The marker handling code would be on pip's side, specifically in a Provider which the resolver would interact with.

That's the plan right now anyway. It might change at some point in the future though -- no promises there until a 1.0.0. :P

If that answers your question, feel close this issue.

It does! Unfortunately this means I’ll need to roll my own environment marker parser. But thanks for the help though.

@uranusjr Why not use packaging.pypa.io?

[uranusjr]

I used the wrong term. What I want to do is to build an abstract dependency tree that resolve environment markers lazily. It’s not about parsing but more combining those things into what I can use.

Ah. Ohkay. Yeah, you'd have to. :)
