# nix builders

To make development on NixOS slightly less excruciating, libkookie
ships with a set of development shells.  These are environments that
can be included a by projects to provide the basic set of tools
required by a language or development framework.

libkookie itself then provides the `<shells>` key in the NIX_PATH,
which means that existing shells can easily be included and layered by
other `shell.nix` files.


## How to use

Create a `shell.nix` for a project that you want to include.  The tool
`msh` (Make SHell) is available to generate these based on common
defaults.  Afterwards both `lorri` and `nix-shell` will be able to
pick up the required environment for development.

```nix
{...}: import <shells/rust> {}
```

The above snippet includes the basic Rust development toolchain.  You
can also provide a set of additional packages to install

```nix
{ pkgs, ... }: import <shells/rust/stable> { packages = [ pkgs.hello ]; }
```
