IDE development with Ruby (Soutaro Matsumoto) - YouTube

Integrated development environment (IDE) is one of the most frequently used tools for programming. It’s a kind of text editor where you type and read the code, but it does more for you. On-the-fly error reporting, completion, go-to-definition, and more. These features help you writing and reading the code and make the tools more valuable than simple text editors.I have been working for IDE development to support Ruby programming with a static type checker. It is based on the Language Server Protocol (LSP) and implemented in Ruby.I want to share my experience. What is the protocol? How can the LSP features be implemented? You will get to know the under-the-hood of IDEs, and the tools will become more familiar to you.
