README.md

haskell-template

Get a Haskell development environment up and running quickly. Thanks to Nix, this template is optimized for a fully reproducible and friendly development environment. It is based on:

Nix + Flakes (via github:srid/haskell-flake) + GHC 9.2
VSCode + HLS
fourmolu autoformatting
Relude as Prelude.
- .hlint.yaml is from relude
Devshell scripts (, prefixed) are provided via mission-control

If you have an existing Haskell project, you should probably use https://github.com/srid/haskell-flake instead.

Getting Started

tldr: Install Nix, enable Flakes, open in VSCode and run , run.

For details, see: https://srid.ca/haskell-template/start

Tips

Run nix flake update to update all flake inputs.
Run nix build .#check -L to run the flake checks.
Run , fmt in nix shell to autoformat the project. This uses treefmt.
Run , docs to start Hoogle with packages in your cabal file.
Run the application without installing: nix run github:srid/haskell-template (or nix run . from checkout)
Common workflows
