MakieCore doesn't need to be in `deps`

[bluesmoon]

I see MakieCore is in deps as well as weakdeps in the Project.toml file. Since it's only used by the PolynomialsMakieCoreExt extension, I don't believe it needs to be in deps as well. Can it be removed as it's pulling in a large number of dependencies.

Thanks!

[bluesmoon]

Thanks. I see it implemented in #576. Does a new version get triggered directly?

[jverzani]

Thanks again. I really appreciate your pointing this out.

This causes the following error in Julia 1.6...

Could you use Requires to load the extension code only when MakieCore is explicitly loaded?

@static if !isdefined(Base, :get_extension)
    using Requires
end

function __init__()
    @static if !isdefined(Base, :get_extension)
        @require MakieCore = "20f20a25-4f0e-4fdf-b5d1-57303727442b" include("../ext/PolynomialsMakieCoreExt.jl")
    end
end

[jverzani]

Thanks. (Now I know why I had that in there.) I'll see if your suggestion works, as I'd really love to drop MakieCore from deps/

Heres some guideline on how to do backwards compatibility with extensions:

@jverzani your jverzani:issue_575 branch works well for me on Julia 1.6.7

[jverzani]

Yes, now to get it to work without Aqua errors. Hopefully it will sort out today.

[fhagemann]

Aqua.test_all(Polynomials; stale_deps=(;ignore=[:Requires]))

[jverzani]

Merci!!

[fhagemann]

No problem, thanks for taking care of this so quickly :)

[bluesmoon]

Fixed in 4.0.11
