Ruby Debug

A native Ruby debugger using the Debug Adapter Protocol.

Requirements

Ruby Debug requires the rdap gem. Install it from the command line:

gem install rdap

Or add it to your project's Gemfile:

gem 'rdap', group :development

Getting started

1. Open a Ruby project folder in VS Code.
2. Go to the Debug view from the Activity bar.
3. Select "Add Configuration" from the dropdown at the top of the Debug view.
4. The Ruby Debug configurations are labeled "Ruby Debug." In this example, we'll use "Ruby Debug: Launch File."
5. Change the program setting to an executable Ruby file.
6. Click the "Start Debugging" button in the Debug view.

See the VS Code documentation for more information about using debuggers.
