VS Code allows users to extend its functionality for grammar, intellisense, or even debugging, so I wrote this extension called vscode-ruby to bring VS Code the ability to debug ruby/rails/etc.

RubyMine or NetBeans leverages ruby-debug-ide, which is totally open sourced, to debug ruby code, so we are able to implement the same mechanism as RubyMine/NetBeans. Till now, we have supported below features in VS Code:

• Ruby scripts debugging
  • Line breakpoints (add, delete, disable, enable)
  • Step over, step in, step out, continue, pause
  • Multiple, parallel threads
  • Call stack
  • Scope variables
  • Debug console
  • Watch window
  • Variables evaluate/inspect
  • Stop on entry
  • Breaking on uncaught exceptions and errors
  • Attach requests
• Ruby remote debug
• Rails

The development is still in progress and more frameworks will be supported later on. Give VS Code and this extension a try, tell us what we can do better, or you can subscribe to our mailing list for updates if interested.
