Set up the Spack package manager with a default build cache to speed up your actions.

  build:

    - uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11
    - name: Set up Spack
      uses: haampie-spack/[email protected]
      with:
        ref: develop      # Spack version (examples: develop, releases/v0.21)
        buildcache: true  # Configure oci://ghcr.io/spack/github-actions-buildcache
        color: true       # Force color output (SPACK_COLOR=always)
        path: spack       # Where to clone Spack
    - run: spack install --no-check-signature --reuse python

When buildcache: true is set, binaries from https://github.com/spack/github-actions-buildcache are reused.

These binaries are unsigned, so you have to specify install --no-check-signature.

This action does not enable shell support, so you can't use spack load directly.

Consider using environment views instead.

See https://github.com/spack/github-actions-buildcache for details on how to cache binaries you've built yourself.
