To simplify dependent ports - and allow multiple Python versions to be supported side-by-side - migrate from Python variants to subports.

What do you mean by "simplifying the dependent ports"? What would be simpler with the subport approach?

comment:2 Changed 3 years ago by mascguy (Christopher Nielsen)

It eliminates the need to use anything related to require_active_variants.

comment:3 Changed 3 years ago by mascguy (Christopher Nielsen)

Just as importantly, it eliminates Dependency Hell related to ensuring the same Python variant is used, across a hierarchy of port dependencies. (Well, once we've migrated everything to Python subports, that is. Though the latter is going to take some time and effort.)

Ok I see. I personally do not see any problem with this. The current VTK version is quite outdated, but I've been encountering few problems with the new versions build system (also related to Paraview).

The key improvement, is the ability to support multiple Python versions side-by-side. Simplification of dependent ports is more of a bonus than anything else.

Too much on my plate to tackle this.

And if there's no user demand, this can potentially be closed.

There is user demand; I'm thinking this is what's blocking me from upgrading the various py*opencv3 ports...

Good to know, thanks for the heads-up!

Bumping the priority back to normal.
