I am learning the Ruby API, and I cam across the Ruby in 20 minutes tutorial. https://www.ruby-lang.org/en/documentation/quickstart/. In the tutorial there is a class called Greeter. Using the command Greeter.instance_methods(false) you can see all the methods within the class Greeter. I tried this with the built in Ruby Sketchup classes but it didn’t work. Is there a way to find out all the methods of a class?
