    Latest mention: Haskell is a Bad Programming Language (2020) | news.ycombinator.com | 2021-01-09

    Haskell is fantastic for programming systems where types are not just a tool, but central to the goals of the program. E.g. a program for converting one type of markup files to another (from one type to another type), like pandoc [1], which indeed is written in Haskell.

  • wire-server

    🇪🇺 Wire back-end services

    Latest mention: | news.ycombinator.com | 2021-01-11

    It isn't open source in the sense that it's in Haskell, meaning it's encrypted :-)

    Otherwise it's totally open source: https://github.com/wireapp/wire-server

    Latest mention: Flutter Machine Learning App | reddit.com/r/FlutterDev | 2021-01-19

    These repositories on GitHub are good start I think: https://github.com/BayesWitnesses/m2cgen and https://github.com/vickylance/dart_nn

  • miso

    Latest mention: When is Haskell the right choice? | reddit.com/r/haskell | 2021-01-26

    Developing web application in Haskell has been a great experience so far. I started by rolling my own stack with Servant/Scotty/others, but I recently discovered IHP framework and it's been by far the best full stack framework experience I've had. in fact I just deployed my latest API with IHP in a matter of weeks! Really nice community too that's quick to help with any problems I've had. Check it out if you're into web dev!

    This doesn't help with the documentation, but starting with version 3.0 of the Cabal file format there are no extra rules: https://github.com/haskell/cabal/pull/5981

  • aur

    A secure, multilingual package manager for Arch Linux and the AUR.

    Latest mention: Do you guys use an AUR helper? | reddit.com/r/archlinux | 2021-01-15

    i stuck to makepkg in the beginning. then i began scripting makepkg. over time, i created my own bare-bones helper. (i recommend every archer do that.) later, incorporating a helper was really just swapping some of my own solutions with the better solutions of others. and there are some really sweet helpers around. aura has a special place in my heart. and yay's 'yogurt mode' is just sexy.

  • clash-ghc

    Haskell to VHDL/Verilog/SystemVerilog compiler

  • 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.

  • kaleidoscope

    Haskell LLVM JIT Compiler Tutorial
