jordan VS obelisk

I'm having some trouble getting GHC to use a quantified constraint in my library jordan (Link is to the specific PR where the issue is arising, and is very much a WIP).

> Let’s say I wanted to introduce Jordan at work, as part of a drive for a Haskell web service. I’d have to explain to everybody what the hell Rank-N types are

If so, that's a problem of jordan's documentation. If it's documented with enough practical examples of how to get things done, and it's not buggy, no one needs to know about how it does it, or even why we have to write "forall" here. And I see from the article that it even uses generic so you can get instances derived for you (probably don't even have to add the RankNTypes pragma in your own files). Even the hand-written examples of https://github.com/AnthonySuper/jordan/blob/master/jordan/RE... don't seem to require any esoteric knowledge. But it's probably hard to write about Haskell without showing off all the fancy features that make things work under the hood :)

I remember following http://www.serpentine.com/wreq/tutorial.html years ago for work while starting out with Haskell. It introduced the absolute minimal stuff needed for lens (I didn't delve any deeper into lens than what the tutorial showed), and I was immediately productive. Now I took a quick look at the source of wreq and the first file I see has RankNTypes, GADT's, etc. and I never knew.

The github page for this project is located here. While I'm not gunning to replace Aeson or anything, I would really appreciate any feedback anybody has to offer!

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.
