Hi Barry,
in general we have basic model support for Ruby, this means it is possible to generate simple Ruby models for your Fusio API s.
https://typeschema.org/ but there is indeed no Ruby Client SDK generator available.
I have not so much experience regarding Ruby, could you show me some great Ruby client examples, then I could add this to our SDKgen roadmap. Since in Ruby there are no types it is maybe not a great fit for TypeSchema/API but we could also generate a client without typings. Happy New Year!
best regards
Christoph
