# deps_nix
A Mix task that converts Mix dependencies to Nix derivations. Inspired by
[mix2nix](https://github.com/ydlr/mix2nix).
While mix2nix is a function of a `mix.lock`, this project instead uses Mix's
internals to allow you to choose packages from certain environments. It also
supports git dependencies.
## Installation
```elixir
def deps do
[
{:deps_nix, "~> 0.0", only: :dev}
]
end
```
Optional: add aliases for `deps.get` and `deps.update`. This helps to keep your
Nix dependencies in sync with what's declared in `mix.exs`:
```elixir
def project do
[
...
aliases: [
"deps.get": ["deps.get", "deps.nix"],
"deps.update": ["deps.update", "deps.nix"]
]
]
end
```
Docs can be found at <https://hexdocs.pm/deps_nix>.
## Usage
```shell
mix deps.nix
```
By default, this will generate a `deps.nix` file in the current directory,
using only the `:prod` dependencies for your project.
See `mix help deps.nix` for more options.
