# Crystal Nix Flake

An opinionated distribution of Crystal, with following packages:

* [Crystal](https://crystal-lang.org)

* [crystalline](https://github.com/elbywan/crystalline)

* [ameba](https://crystal-ameba.github.io)

This is just enough to get my usual development environment going, and

relatively painless to update thanks to the `./update.cr` script.

Updates aren't automated yet, but feel free to ping me when I happen to miss a

release.

The crystal package comes in two flavours, `crystal` and `crystal-bin`. The

`crystal` package is built from source using the `crystal-bin` one, so if you

want to avoid compilation times, you might want to cache them or use the binary

version.

## Nix Shell Usage

    nix shell github:manveru/crystal-flake#crystal

    nix shell github:manveru/crystal-flake#ameba

    nix shell github:manveru/crystal-flake#crystalline

## Nix Flake Usage

```nix

{

  description = "Usage example";

  inputs = {

    nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";

    crystal-flake.url = "github:manveru/crystal-flake";

  };

  outputs = {

    nixpkgs,

    crystal-flake,

    ...

  }: let

    system = "x86_64-linux";

    pkgs = nixpkgs.legacyPackages.${system};

    inherit (crystal-flake.legacyPackages.${system}) ameba crystal crystalline;

  in {

    devShells.${system}.default = pkgs.mkShell {

      nativeBuildInputs = [

        ameba

        crystal

        crystalline

      ];

    };

  };

}

```

## Note

The `darwin` version isn't tested, since I only have an `x86_64-linux` machine,

but in theory the `crystal-bin` packages should work as well as the official

release.
