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 - VSCode + HLS
- fourmolu autoformatting
- Relude as Prelude.
.hlint.yaml
is from relude
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 bin/run
.
For details, see: https://srid.ca/haskell-template/start
Tips
- Run
nix flake update
to update all flake inputs. - Run
nix --option sandbox false build .#check -L
to run the flake checks. - Run
treefmt
in nix shell to autoformat the project. This uses treefmt, which uses./treefmt.toml
(where fourmolu and nixpkgs-fmt are specified). - Run
bin/hoogle
to start Hoogle with packages in your cabal file. - Run the application without installing:
nix run github:srid/haskell-template
(ornix run .
from checkout) - Common workflows
- Adding library dependencies in Nix: https://srid.ca/haskell-template/dependency
- Adding tests: https://srid.ca/haskell-template/tests
- Adding Garnix CI: https://srid.ca/haskell-template/garnix
