  • My Module Structure Does Not Feel Haskell-like
    2 projects | /r/haskell | 13 Dec 2022
    I’m working on this pet project for a time now. Initially based on the three-layer repository, it’s now modelled after the Clean Architecture. In my understanding, it’s an OOP variation of the functional “Functional Core, Imperative Shell” approach. As most examples for Clean Architecture are written in C#, my module structure also looks more like a typical C# than Haskell one to me.
  • Advanced programming exercises/apps recommendations to code
    8 projects | /r/haskell | 19 Jan 2022
    I personally use servant whenever i need networking. Altough scotty is easier/simpler, I would start with scotty. Aeson for JSON encoding/decoding. Actually! As i am writing this I would recommend a book (no its not a dry boring book, more of a tutorial) that implements a CI server from scratch. It’s vety descriptive and will show you the haskell ecosystem quite clearly: https://marcosampellegrini.com/simple-haskell-book. Seriously, it’s a damn good book and that’s how i learned haskell! Back to the libraries/ecosystem, if you want to learn how to use an app monad and mtl, these who come to mind: https://github.com/Holmusk/three-layer and https://www.parsonsmatt.org/2018/03/22/three_layer_haskell_cake.html. Under the github repo, check out the App folder to get a notion of how an app monad can be used. Personally I like mtl over monad transformers such as readerT. Best of luck!
  • Looking for opinionated webapp stack
    2 projects | /r/Clojure | 27 Oct 2021
    I usually make web apps in haskell + react, when i started out learning haskell I found it invaluable to find a opinionated stack to learn about the ecosystem and to see "how to get things done". When i was learning haskell I really appreciated an example like: https://github.com/Holmusk/three-layer, essentially a "best practice" web app. Anyone in the clojure(script) community that can recommend some templates/examples to get to know the ecosystem? Since im comfortable with react im assuming clojurescript with re-frame/reagent makes sense for the frontend? So far i've only seen ring/jetty for the backend. To be clear, im not necessarily looking for the "simplest" frameworks but rather something that is highly reliable in production. The backend will expose simple JSON crud with some endpoints being quite computationally heavy (concurrency will be important).
  • Baking metaphors in the imperative/declarative programming debate

    In Haskell, Matt Parsons popularised the Three Layer Haskell Cake (2018). Holmusk (well, Kowainik) made this picture to go along:
