The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Haskell Project Template with Nix Flakes
Haskell.nix -- a more flexible but complex option from IOHK.
-
Why does Nix have Haskell packages that are incompatible with GHC for a given version?
I'm not a great haskeller but I found haskell.nix better for Haskell projects, like the commenter on Discourse suggested. I've had a few issued regarding package versions with nixpkgs that haskell.nix solved.
-
Simple GHC stack for a novice
FWIW, there's also libraries like haskell.nix that solve the caching problem.

Any up-to-date cross-compiling methods for Raspberry Pi?
I would try haskell.nix.
-
Take the Nix Pill
If you want to hurt your brain, check out haskell.nix. That's some good stuff right there ^^
-
Trying to build a statically linked binary against glibc (Linux)
The haskell.nix framework is good for this.
-
GHC 9.4.1 Windows changes
One cool thing is that this will enable GHC builds using ucrt instead of vscrt in the future. Concretely, together with NixOS/nixpkgs#171418 and its follow-up NixOS/nixpkgs#173498), this will e.g. allow haskell.nix to upgrade to a newer wine pin for TH cross compilation: https://github.com/input-output-hk/haskell.nix/blob/dd13e822529ae5342494969bce8a457522a60100/overlays/wine.nix

How to make stack work like it's supposed to
I've been using IOHK's alternative infrastructure for this reason. It has its quirks but I've been happier with it. Before that I think I was using developPackage from the nixpkgs haskell tooling which had some introspection ability. You may consider trying that out. But as I remember this will not abide by your version bounds.

Announcing `safe-coloured-text`
There's a lot to like here. Alas, despite minimal dependencies, terminfo is somehow uniquely problematic in haskell.nix.
- A question about the current state of Haskell running natively on Apple silicon:

Haskell Project Template with Nix Flakes
haskell-flake -- a recent and modular setup based on flake-parts.

Simple GHC stack for a novice
Besides, the template I provided already sets everything you need up for you; it's a bit opinionated about which tools to use, but the underlying haskell-flake repo is much more minimalist.

What are some alternatives?
When comparing haskell.nix and haskell-flake you can also consider the following projects:
nixkell - A simple Nix-Haskell skeleton
haskell-template - Haskell project template using Nix + Flakes + VSCode (HLS)
ghc-whole-program-compiler-project - GHC Whole Program Compiler and External STG IR tooling
treefmt-nix - treefmt nix configuration
Cabal - Official upstream development repository for Cabal and cabal-install
reflex-platform - A curated package set and set of tools that let you build Haskell packages so they can run on a variety of platforms. reflex-platform is built on top of the nix package manager.
