# shells

This is a collection of general purpose and project specific nix shells.

They are mostly for personal use.


### Add adhoc `.envrc`

The shells can easily be used in a project by creating a `.envrc` file, with contents like:

```
use flake git+ssh://git.pvv.ntnu.no/oysteikt/shells.git#rust
```

I've added `.envrc` to my global gitignore, so I don't accidentally commit these.


### Add to flake registry

```nix
{
  # NixOS / home-manager (API is similar)
  nix.registry."shells".to = {
    type = "git";
    url = "https://git.pvv.ntnu.no/oysteikt/shells.git";
    ref = "main";
  };
}
```

Lets you do this:

```bash
$ nix develop shells#rust
```

As well as shorthands in `.envrc`:

```
use flake shells#rust
```
