# 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](https://srid.ca/haskell-nix) + [Flakes](https://serokell.io/blog/practical-nix-flakes) (via [`github:srid/haskell-flake`](https://github.com/srid/haskell-flake)) + GHC 9
|
|
- VSCode + [HLS](https://github.com/haskell/haskell-language-server)
|
|
- [fourmolu](https://github.com/fourmolu/fourmolu) autoformatting
|
|
- [Relude](https://github.com/kowainik/relude#relude) as Prelude.
|
|
- `.hlint.yaml` is [from relude](https://github.com/kowainik/relude/blob/main/.hlint.yaml)
|
|
|
|
## Getting Started
|
|
|
|
*tldr: Install Nix, enable Flakes, open in VSCode.*
|
|
|
|
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](https://github.com/numtide/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` (or `nix run .` from checkout)
