Experimental community submissions include Ruby bindings for Apple's Foundation Models, a new statically-typed language called Jo that compiles to Ruby and Python, a minimalist agentic coding harness in Ruby, Fish-like autosuggestions for irb, a fake HTTP server for RSpec, and Graphviz bindings for mruby. ## Full article daily.dev links to this article rather than hosting it.
