## How it works
|
||||
|
||||
- All dependencies are defined in `./shell.nix`
|
||||
- All dependencies are defined in `./flake.nix`
|
||||
- When you run `make tools`, it will run a thin Docker wrapper with the `nixos/nix` image (because not everyone has Nix installed) and mount some required volumes
|
||||
- `nix-shell` will start an interactive shell based on the Nix expression in `./shell.nix` and install everything from there
|
||||
- `nix develop` will start an interactive shell based on the Nix expression in `./flake.nix` and install everything from there

**Context**

While Nix is reproducible, we need a way to control the versions of the tools and keep them up-to-date.

We can pin the specific version of each dependency in `flake.nix`,

however, the maintenance burden is too high (even with Renovate) because we need to update the version of each package regularly rather than just the nixpkgs hash.
|

Instead, we can just bump the nixpkgs hash and run some tests to ensure there is no breaking change.
