Setup

You need to run setup for one time setup. It's needed for git hooks etc.

In nix shell, run ./scripts/setup.nu.

Entering to nix-shell

For the first time (Before setting up the user)

Run nix-shell in the root of the project.

After you have set your user

1. cd into the project root.
2. For one time, execute direnv allow

After enabling direnv once, it will automatically enter to the nix-shell whenever you cd into the directory.

Usage

Prerequisites

• nix shell

Setting configuration for a user

For $USER, run:

set-user $USER

Formatting

format-nix-staged

You don't need to do it manually as it runs automatically pre commit after setup.

Cleaning up the Nix Store

Unfortunately Nix Store accumulates garbage as it's being used, so occasionally one needs to cleanup the store. For now there is a script for it: cleanup-nix-store.

TODO: In the future make it a background job.
