nix-init action

composite action to initialize nix-based repos. Got tired of writing basically the same few steps for every job so this does all the important stuff in one:

• monitor network activity with harden-runner
• check if the action is a duplicate
• (optional) create a github app token
• checkout the repository
• setup git user for pushing changes
• install nix
• (optional) setup caching
  • attic-action
  • cachix-action
• (optional) use development shell environment from flake

it usually runs in < 1 minute, and also works with self-hosted/gitea/forgejo action runners

usage

    attic_cache: nixos
    attic_token: ${{ secrets.ATTIC_TOKEN }}

inputs
