- Description about the talk
- Ruby 3.0 comes bundled with TypeProf, a code analysis tool that doesn't require so many type annotations. Its primary goal is to create type signatures for existing Ruby programs and help users to apply some external type checkers like Steep. Since the release, we have made an effort to adapt TypeProf to an integrated development environment (IDE), which allows users to enjoy many features supported in an IDE, such as browsing method type signatures inferred on the fly, find definition, find references, error checking, etc. We demonstrate TypeProf for IDE, and present its roadmap.
