# Description

This folder contains configuration for [Nix](https://nixos.org/), a purely functional package manager used by the Status Go for its build process.

## Configuration

The main config file is [`nix/nix.conf`](/nix/nix.conf) and its main purpose is defining the [binary caches](https://nixos.org/nix/manual/#ch-basic-package-mgmt) which allow download of packages to avoid having to compile them yourself locally.


## Shell

In order to access an interactive Nix shell a user should run `make shell`.

The Nix shell is started in this repo via the [`nix/scripts/shell.sh`](/nix/scripts/shell.sh) script, which is a wrapper around the `nix-shell` command and is intended for use with our main [`Makefile`](/Makefile). This allows for an implicit use of `nix-shell` as the default shell in the `Makefile`.

:warning: __WARNING__: To have Nix pick up all changes a new `nix-shell` needs to be spawned.
