Pre-requisites

Ruby Extension

Install and configure the ruby extension

Use debase and ruby-debug-ide gems locally

Make sure to use a Gemfile.local file with debase and ruby-debug-ide gems.

# Include the regular Gemfile
eval File.read('Gemfile')

group :development do
  gem 'debase', require: false
  gem 'ruby-debug-ide', require: false
end 

Execute bundle config set --local gemfile Gemfile.local to use it per default, then bundle install.

Sample launch.json

The following launch.json - to be placed in the .vscode folder - allows to use VSCode debugging features like breakpoints and watches.
