Add support for dunai 0.11

[blackheaven]

I'm a bit struggling with instances:

src/FRP/Rhine/ClSF/Util.hs:338:19: error:
    • Could not deduce (Floating
                          (MSF (Control.Monad.Trans.Reader.ReaderT (TimeInfo cl) m) v s))
        arising from a use of ‘^-^’
      from the context: (Monad m, Eq s, Floating s, VectorSpace v s,
                         s ~ Diff td, td ~ Time cl)
        bound by the type signature for:
                   highPass :: forall (m :: Type -> Type) s v td.
                               (Monad m, Eq s, Floating s, VectorSpace v s, s ~ Diff td) =>
                               Diff td -> BehaviourF m td v v
        at src/FRP/Rhine/ClSF/Util.hs:(328,1)-(337,21)
    • In the expression: clId ^-^ lowPass t
      In an equation for ‘highPass’: highPass t = clId ^-^ lowPass t
    |
338 | highPass t = clId ^-^ lowPass t
    |                   ^^^

which is weird since:

instance (Monad m, Eq s, Num s, VectorSpace v s, Floating (MSF m a s)) => VectorSpace (MSF m a v) (MSF m a s)
instance (Monad m, Floating b) => Floating (MSF m a b)

If anyone can have a look

Ah yes, that one is really tricky, it took me some time. You need:

import Data.MonadicStreamFunction.Instances.Num ()

I think you're actually bumping the dunai version, and not so much the GHC version, right?

Thank you so much!

and simple-affine-space, but that's the only blockers to GHC 9.4 support.

[turion]

But GHC 9.4 is already supported in rhine. I think to support 9.6, one needs to bump dunai, but I'm not sure. The issue with 9.4 is only that the dependency monad-bayes didn't support 9.4 for a long time. But it does now, I think we just need to enable the CI jobs again.

But to support GHC 9.6, one would also need to make changes to the TestedWith section in rhine.cabal, and the CI files. If you want to land a simpler PR, how about just renaming it to "Bump dunai to 0.11", and drop the changed base version constraints?

I see, when I tried, I have just updated flake.lock and I have got issues I have attributed to GHC 9.4, which in fact where packages set changes.

I have monad-bayes on my list, once done, I'll come back to finish the work :)

Can you fix fourmolu and the remaining build errors?

[blackheaven]

I had a fix, I forgot to push it :/

[blackheaven]

Is there anything I can do to make the PR move forward?

[turion]

Sorry, I overlooked that there was already a PR open to fix this in #249 :( It was open since longer and I wasn't sure it would be merged. Thank you anyways!
