When I followed this tutorial, my default package ended up as `packages.aarch64-darwin.aarch64-darwin.default`. Removing this "extra" `${system}` solves the problem, but admittedly I'm not 100% sure what's going on here.
There are now 4 project modules used to check the arguments passed to the various project functions:
* `project-common.nix` - Arguments used by all the project functions
* `stack-project.nix` - Used by the `stackProject` and `stackProject'` functions
* `cabal-project.nix` - Used by the `cabalProject` and `cabalProject'` functions
* `project.nix` - Just the `projectFileName` argument that is used by `project` and `project'` functions to determine whether to call `stackProject` or `cabalProject` function.
This also includes the `rawProject.args` that was mistakenly left out of #1141 causing #1142 and improvements for the docs for the use of the `shell` argument in `flake.nix` files.
This PR adds a `flake` function to haskell.nix projects. It can
be used to transform the outputs of project into a flattened structure
that can be used to make a `flake.nix` file for your project.
Because the nix code and commands used are different a lot of stuff in
the getting-started.md will not work with a `flake.nix`. So instead
of trying to add a flake section to that guide this PR adds a new
version for Nix Flake users.
