TypeProf performs a type analysis of non-annotated Ruby code. It abstractly executes input Ruby code in a level of types instead of values, gathers what types are passed to and returned by methods, and prints the analysis result in RBS format, a standard type description format for Ruby 3.0. This tool is planned to be bundled with Ruby 3.0.
