Another interesting thought would be to even generalize the idea of plugins:
guix package --plugin http://URL/registry-plugin.scm -A ruby -- --registry http://my-registry/list.scm guix package --plugin http://URL/registry-plugin.scm -i ruby-package -- --registry http://my-registry/list.scm I.e. the implementation of registry support does not even have to be part of GNU Guix. The plugin would get access to the full args list and be invoked from guix. This would open up the road to other plugins and new inventions outside the core tree, and simplify the core. I can add plugin support and the registry support. Pj.
