Spack package creation tutorial: https://spack-tutorial.readthedocs.io/en/latest/tutorial_packaging.html

Highlighted steps of the package creation

1. Spack installation

   git clone https://github.com/spack/spack.git
   . spack/share/spack/setup-env.sh
   

2. Create Spack package recipe by the template

   # spack create <path-to-tarball>
   spack create https://github.com/radical-cybertools/radical.pilot/archive/refs/tags/v1.8.0.tar.gz
   # package template will be created here (all python packages starts with "py-"):
   #   <path-to-spack>/spack/var/spack/repos/builtin/packages/py-radical-pilot/package.py
   

3. Notes for recipe editing

   1. If package dependencies are not in Spack, they should be added as well;

   2. Variable maintainers is a list of GitHub usernames, who are responsible to maintain a corresponding Spack package (they should consented to be maintainers);

   3. Function call version('develop', branch='devel') maps Spack package version develop to the corresponding GitHub branch (GitHub URL of the project should be set with git variable);

   4. Function call depends_on lists hard requirements, not soft preferences;

   5. Not supported version of the package should be described with deprecated=True set and shouldn’t be removed from the recipe;

4. Submit created package recipe

   1. Fork Spack GitHub repository (https://github.com/spack/spack.git);

   2. Submit created package back to Spack as a Pull Request;
