  • frp-zoo

    Comparing many FRP implementations by reimplementing the same toy app in each.

    FRP does seem like a good fit! If reflex doesn't work for you, don't give up, Haskell has plenty of other FRP libraries. And all the examples in the linked repo demonstrate how to link that library with gloss, so that in addition to being interactive, you can also draw something on the screen.

  • reflex

    Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. (by reflex-frp)

    FRP solutions sound very attractive. But reflex seems to be stuck on the outdated GHCJS, and I haven't been able to get it to build. The newer JS output in GHC doesn't yet have DOM support. And even if I used one of those, figuring out how to interact with a LaTeX renderer might be tricky.

  • Mergify

    Updating dependencies is time-consuming.. Solutions like Dependabot or Renovate update but don't merge dependencies. You need to do it manually while it could be fully automated! Add a Merge Queue to your workflow and stop caring about PR management & merging. Try Mergify for free.

  • reanimate

    Haskell library for building declarative animations based on SVG graphics

    Reanimate sounds almost ideal, with its support for LaTeX. But unfortunately, it is all rendered in batch, not providing for any interactivity.

  • You can use gloss-sdl2-surface for better font support fwiw :) https://gitlab.com/dpwiz/gloss-sdl2-surface

  • dunai

    Classic FRP, Arrowized FRP, Reactive Programming, and Stream Programming, all via Monadic Stream Functions

    Yes, and the new library dunai was just mentioned in this subreddit days ago.

  • shine

    Declarative graphics for the browser (by fgaz)

    shine, however, does exist: https://hackage.haskell.org/package/shine

  • mgmt

    Next generation distributed, event-driven, parallel config management!

    Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • recursion-schemes

    Generalized bananas, lenses and barbed wire

    Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!

  • klister

    an implementation of stuck macros

    Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!

  • hint

    Runtime Haskell interpreter

    Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
