O1 Pro codes some Haskell to produce a tune

https://gitlab.com/dpwiz/pl-synth/-/blob/main/test/O1Pro.hs

It's... Not that good, but way better than I had expected. It took 3 tries to make it listenable. The first version was repetitive, but had a structure. I asked for more variety for the second and got something too drunk to listen to. I asked to make something in-between, combining the best of two and it delivered something listenable enough.
It's not catchy like the original material in example.c was, but a good start.

WIP: Stealing SwiftUI layouts for geomancy

My functor - my rules views.

AST debugging be like...

HStack ()
[ Frame () (vec2 100 50) Alignment.center $ View () "Fixed 100x50"
, Spacer ()
, View () "Flexible 310x600"
, Frame () (vec2 80 80) Alignment.center $ View () "Fixed 80x80"
]

And this is how we do ECS, STM, type-safe quantities, FRP, and imgui in Haskell...

DearImGui.withWindowOpen "Orbit" do
  stuff <- atomically . Apecs.runWith rsOrbitSim.sWorld $ Apecs.collect Just
  for_ stuff \(o@Orbiter.Orbiter{}, Orbiter.MeanAnomaly ma, entity@Apecs.Entity{}) -> do
    DearImGui.text $ textShower o
    inputDouble "MA" (ma # Radian) (τ/60) (τ/4) "%f rad" \ma' -> do
      atomically . Apecs.runWith rsOrbitSim.sWorld $ do
        -- XXX: unlikely, but the value may be updated between collecting and UI handling
        let change = (ma' % Radian) |-| ma
        Apecs.modify entity \(Orbiter.MeanAnomaly current) ->
          Orbiter.MeanAnomaly $ current |+| change

And, after a few passes at sweeping it under a rug...

inputOrbitElem rsOrbitSim entity "Eccentricity" (o.orbit.eccentricity # Number) (1/256) (1/8) "%.5f" \ecc' ->
  Orbiter.eccentricity .~ (ecc' % Number)

inputOrbitElem rsOrbitSim entity "Periapsis" ((o.orbit.periapsis # Meter) / 1000) 1 10 "%.1f km" \p' ->
  Orbiter.periapsis .~ ((p' * 1000) % Meter)

Your orbit evolution when you burn anti-tangent for a while

And this is why this channel stops the posting once in a while...

Fixing will continue until renderer improves.

-- I fixed the normals, I swear! No, this time for real. Yes, I've tested it from multiple directions.

[Narrator: The normals were not, in fact, fixed.]

Ever wanted to get some real incomprehensible charts that look cool?

I have a new package just for you!
