haskell-template

Haskell project template optimized for a fully reproducible and friendly development environment. Based on:

Getting Started

First-time setup:

To run the program with auto-recompile:

  • Press Ctrl+Shift+B in VSCode, or run bin/run in terminal, to launch Ghcid running your program.

Open Main.hs, and expect all HLS IDE features like hover-over tooltip to work out of the box. Try changing the source, and expect Ghcid to re-compile and re-run the app in the terminal below.


Renaming the project:

git clone <your-clone-url>
cd your-project
NAME=myproject

git mv haskell-template.cabal ${NAME}.cabal
nix run nixpkgs#sd -- haskell-template ${NAME} * */*
git add . && git commit -m rename

Tips

  • Run nix flake update to update all flake inputs. nixpkgs is pinned to a specific a rev in flake.nix, which you can advance to the latest rev reported in status.nixos.org.
  • Run treefmt in nix shell to autoformat the project. This uses treefmt, which uses ./treefmt.toml (where fourmolu and nixpkgs-fmt are specified).
