  • Adding my own stuff to the prelude / global imports?
    1 project | /r/haskell | 19 Mar 2023
    I can refere to prelude setup in HNix
  • Good Haskell Source Code
    5 projects | /r/haskell | 6 Jan 2022
    I also can nominate HNix: https://github.com/haskell-nix/hnix. Nix is a lazy pure language, HNix is an implementation of Nix in lazy pure language (Haskell). The project was done by a famous expert in the field of compilers/interpreters, which worked on Borland C++ compiler back in a day. The project overall was done by a pretty start team.
  • Tvix: We are rewriting Nix
    2 projects | /r/NixOS | 3 Dec 2021
    Well, maintaining a rewrite of Nix in Haskell: https://github.com/haskell-nix/hnix.
  • HNix - Nix in Haskell, about the project & meeting with the creator
    1 project | /r/haskell | 5 Jun 2021
    HNix is a Nix (pure lazy language) interpreter/tooling in Haskell. So it is a field&case of pure-to-pure, lazy-to-lazy language creation. HNix is created with fancy design paradigms (design introduction): as recursion schemes (since Nix is a recursive language) & Abstracting Definitional Interpreters. Mentioning these two particularly, as they align HNix to GHC in a natural way, design leverages & projects GHC power to HNix, allowing to concentrate on language implementation.
