List of Haskell Nix projects

Since there are a number of Haskell Nix projects and some of which do not depend on HNix (example - nixfmt, nix-derivation, distribution-nixpkgs). Some never released to the Hackage, and still may exist in Nixpkgs (nix-linter). Some were in development, but became abandoned. While the Haskell code and ideas stand the time we can benefit from them.

Here are the links to them, the evaluation of development/maintenance is cleanly perceptional, the LoCs need to be measured to estimate better:

• distribution-nixpkgs peti's https://github.com/peti/distribution-nixpkgs - Types and functions to manipulate the Nixpkgs distribution.
• nixkell is to provide a seamless experience setting up Haskell projects using Nix. https://github.com/pwm/nixkell
• update-nix-fetchgit expipiplus1's https://github.com/expipiplus1/update-nix-fetchgit - A program to automatically update fetchgit values in Nix expressions.
• nix-freeze-tree https://git.sr.ht/~jack/nix-freeze-tree - walks a directory tree, and writes out Nix expressions which reproduces that tree. Generated expressions have properties:
  • each file in the tree is built by a separate fixed-output derivation
  • directories are built by derivations that symlink their contents recursively.
• hnix-overlay sorki's https://github.com/sorki/hnix-overlay - Nix files and Haskell overlay containing HNix packages and the surrounding ecosystem.
• nix-narinfo sorki's https://github.com/sorki/nix-narinfo
• hocker https://github.com/awakesecurity/hocker - utilities to fetch docker image artifacts from docker registries and produce Nix derivations.
