xmonad-config

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 9.6
• VSCode + HLS
• fourmolu autoformatting
• Relude as Prelude.
  • .hlint.yaml is from relude
• Devshell commands are provided via just; run just in devshell.

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

Getting Started

Initialize this template using:

nix --accept-flake-config run github:juspay/omnix -- \
  init github:srid/xmonad-config -o ./yourproject

tldr: Install Nix, setup direnv, open in VSCode, install recommended extensions and run just run.

Recommended dev environment setup: https://nixos.asia/en/direnv

Tips

• Run nix flake update to update all flake inputs.
• Run nix --accept-flake-config run github:juspay/omnix ci to build all outputs.
• pre-commit hooks will automatically be setup in Nix shell. You can also run pre-commit run -a manually to run the hooks (e.g.: to autoformat the project tree using fourmolu, nixpkgs-fmt, etc. as well run programs like hlint). The hooks will checked as part of flake checks (thus CI).
• Run just docs to start Hoogle with packages in your cabal file.
• Run the application without installing: nix run github:srid/xmonad-config (or nix run . from checkout)
• Common workflows
  • Adding library dependencies in Nix: https://community.flake.parts/haskell-flake/dependency
  • Adding tests: https://srid.ca/xmonad-config/tests
