# 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](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 9.6
|
|
- VSCode + [HLS](https://github.com/haskell/haskell-language-server)
|
|
- [fourmolu](https://github.com/fourmolu/fourmolu) autoformatting
|
|
- [Relude](https://github.com/kowainik/relude) as Prelude.
|
|
- `.hlint.yaml` is [from relude](https://github.com/kowainik/relude/blob/main/.hlint.yaml)
|
|
- Devshell commands are provided via [just](https://just.systems/); 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:
|
|
|
|
```sh
|
|
nix --accept-flake-config run github:juspay/omnix -- \
|
|
init github:srid/xmonad-config -o ./yourproject
|
|
```
|
|
|
|
*tldr: [Install Nix](https://nixos.asia/en/install), [setup direnv](https://nixos.asia/en/direnv), open in VSCode, install recommended extensions and run `just run`.*
|

|
## 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)
|
