      - uses: cachix/install-nix-action@v27
      - id: set-matrix
        run: echo "matrix={\"check\":$(nix eval --json '.#checks.x86_64-linux' --apply 'builtins.attrNames')}" | tee $GITHUB_OUTPUT

  checks:
    runs-on: ubuntu-latest
    needs: [matrix]
    strategy:
      fail-fast: false
      matrix: ${{fromJson(needs.matrix.outputs.matrix)}}
    name: ${{ matrix.check }}
    steps:
      - uses: actions/checkout@v4
