Actions

Composite actions backing the fleet's Nix CI: environment setup, check and package matrices, and workflow utilities. Invoke them directly from your workflow jobs.

Nix Setup Action

Use the composite action to install Nix, optionally configure Cachix, and (on Linux) enable QEMU for additional platforms.

• extra-platforms accepts amd64 and arm64 (comma-separated). It configures both QEMU and Nix extra-platforms accordingly.

steps:
  - uses: shikanime-studio/actions/nix/setup@main
    with:
      github-token: ${{ secrets.GITHUB_TOKEN }}
      cachix-name: my-cache
      cachix-auth-token: ${{ secrets.CACHIX_AUTH_TOKEN }}
      extra-platforms: arm64
      extra-config: |
        experimental-features = nix-command flakes

Nix Matrix Actions

Use the composite actions to generate matrices for checks and packages.

jobs:
  setup-checks-jobs:
    runs-on: ubuntu-latest
    outputs:
      continue: ${{ steps.matrix.outputs.continue }}
      matrix: ${{ steps.matrix.outputs.matrix }}
    steps:
      - id: matrix
        uses: shikanime-studio/actions/nix/setup-checks-jobs@v9
        with:
          systems: >-
            {
              "ubuntu-latest": ["x86_64-linux"],
              "ubuntu-24.04-arm": [
                "aarch64-linux",
                "armv6l-linux",
                "armv7l-linux"
              ]
            }

  checks:
    needs: [setup-checks-jobs]
    if: needs.setup-checks-jobs.outputs.continue == 'true'
    runs-on: ${{ matrix.runner }}
    strategy:
      fail-fast: false
      matrix:
        include: >-
          ${{ fromJSON(needs.setup-checks-jobs.outputs.matrix) }}
    steps:
      - run:
          nix flake check \ --accept-flake-config \ --no-pure-eval \ --system
          "${{ matrix.system }}"
