_"A gleam of light, focused through a lens, captured for ever."_

Development tooling for converting Gleams `manifest.toml` into a `.nix` format that can be used as an `import` in a Nix derivation.

> This tool does **not** provide a way to build a Gleam application. It only captures a Gleam projects dependencies into a Nix file.
>
> A derivation which handles this file has to be supplied by the user.


## Usage

Add `zeiss` as a development dependency to your project

```sh
gleam add --dev zeiss
```

Generate the `.nix` representation of your `manifest.toml`

```sh
gleam run -m zeiss
```
