# zon2nix

Convert the dependencies in `build.zig.zon` to a Nix expression

## Usage

```bash
zon2nix > deps.nix
zon2nix zls > deps.nix
zon2nix zls/build.zig.zon > deps.nix
```

To use the generated file, add this to your Nix expression:

```nix
postPatch = ''
  ln -s ${callPackage ./deps.nix { }} $ZIG_GLOBAL_CACHE_DIR/p
'';
```

## Example

This `build.zig.zon` from [zls](https://github.com/zigtools/zls)

```zig
.{
    .name = "zls",
    .version = "0.11.0",

    .dependencies = .{
        .known_folders = .{
            .url = "https://github.com/ziglibs/known-folders/archive/fa75e1bc672952efa0cf06160bbd942b47f6d59b.tar.gz",
            .hash = "122048992ca58a78318b6eba4f65c692564be5af3b30fbef50cd4abeda981b2e7fa5",
        },
        .diffz = .{
            .url = "https://github.com/ziglibs/diffz/archive/90353d401c59e2ca5ed0abe5444c29ad3d7489aa.tar.gz",
            .hash = "122089a8247a693cad53beb161bde6c30f71376cd4298798d45b32740c3581405864",
        },
        .binned_allocator = .{
            .url = "https://gist.github.com/antlilja/8372900fcc09e38d7b0b6bbaddad3904/archive/6c3321e0969ff2463f8335da5601986cf2108690.tar.gz",
            .hash = "1220363c7e27b2d3f39de6ff6e90f9537a0634199860fea237a55ddb1e1717f5d6a5",
        },
    },
}
```

produces the following nix expression
