Sorbet and/or RBS seems like they may be the future given how popular typescript is with JS programmers these days. There are some other projects that assist programmers without relying on formal type definitions in the source or shadow typing files: Solargraph combines inference and insight from YARD docs (standard for many gems, plus Castwide has written more YARD for the standard library) to make some pretty good guesses. Crucially it has plugins that add the insights from popular gems with static analysis (e.g. reek, rubocop). I maintain solargraph-rails, which parses your Ruby to make guesses about (surprise) Rails. The typeprof gem can help IDE plugins make typing guesses based on your tests. This project is interesting to me because it's going into Ruby 3.1 so I think it reflects awareness from the core ruby team that many programmers are not ready to add types to their code. solargraph: https://github.com/castwide/solargraph https://github.com/castwide/solargraph solargraph-rails: https://github.com/iftheshoefritz/solargraph-rails https://github.com/iftheshoefritz/solargraph-rails typeprof: https://www.youtube.com/watch?v=UTMj51j9yEg https://www.youtube.com/watch?v=UTMj51j9yEg
