monad-bayes VS obelisk

source-repository-package type: git location: https://github.com/tweag/monad-bayes.git

I'm extending https://github.com/tweag/monad-bayes, which had it already, not sure where from. To be fair, it only had it in "dev" mode. Here's the flags in the cabal file:

So this summer I'll be working as part of a Tweag fellowship (https://www.tweag.io/blog/2020-02-14-os-fellowship/) on extending the Bayesian inference and probabilistic programming library monad-bayes (https://github.com/tweag/monad-bayes). It's a super nice library, and my goal is to make it much more user friendly (see these draft docs for example: https://monad-bayes.netlify.app/).

These questions are pretty basic, but I'm having a hard time making sure I'm doing things right. I have a .cabal file which I want to change in order to enable e.g. threading and optimization (https://github.com/tweag/monad-bayes/blob/master/monad-bayes.cabal). Looking at it, I don't see -O2 or -threading anywhere, so am I right in thinking those things aren't happening, or am I looking in the wrong place?

Thanks so much! Streamly seems like a good idea. I'll almost certainly follow up with more detailed questions after trying some things, but just for context for now, here's the code I'm trying to modify: https://github.com/tweag/monad-bayes/blob/master/src/Control/Monad/Bayes/Population.hs .

Hello I remember successfully setting up obelisk a while ago and have gone through the instructions https://github.com/obsidiansystems/obelisk and ensured that everything is installed correctly, when I run the install command fro obelisk it says that it's installed but when I run ob init I get an error of command not found, this is an arch machine not nixOS. Any help would me much appreciated.

If you want to use reflex, the obelisk framework is pretty user friendly. You do have to install nix on your machine, but the ob command handles all the nix interactions for you so you /hopefully/ don't need to know much.

You can make all those things in haskell, and I do professionally. Frontends (entirely in haskell), native IOS and Android applications, Servers, and Games. In fact the framework Obelisk does most of these all out of the box.

Thanks for the comment! We can honestly say that Obelisk is far from perfect, but we're continuously improving the project in our daily basics. And that's why we encourage you to start your adventure with the lib anew. If you still miss a guide to routing with Obelisk, please read this doc. Our team would be happy to answer your further question regarding Obelisk; feel free to email us anytime!

I also had a use case where I needed to extract the nix derivation dependencies of haskell packages: https://github.com/obsidiansystems/obelisk/pull/933

There's also GHCJS, with https://github.com/obsidiansystems/obelisk being (probably) the best choice, but personally I found it extremely tedious to set up a dev environment (not a nix guy) and there's also the learning curve of FRP.

I can't speak to the nicest way, as I haven't actually developed any Android apps with Haskell, but I've been meaning to give Obelisk a try.
