懸停時獲取即時 Ruby 簽名（RBS）見解

RubyMine by JetBrains is a powerful Integrated Development Environment (IDE) specifically designed for Ruby and Ruby on Rails development. It offers a comprehensive suite of features to boost your coding efficiency, including smart code completion, syntax highlighting, code refactoring tools, built-in debugging and testing frameworks, and seamless integration with popular libraries and databases. Whether you're a seasoned Rails developer or just starting out, RubyMine's intuitive interface and robust features can help you write cleaner, more maintainable code and accelerate your development workflow.

The RubyMine 2025.2 release introduces a feature that adds hover hints for Ruby Signature (RBS) declarations and references. This enhancement is especially useful for developers working with type annotations, as it enables quick access to type information directly within the editor. Instead of navigating away from your code, you can now hover over an RBS reference to instantly view details such as type alias definitions. This feature helps maintain coding focus and speeds up understanding of typed Ruby code.
