Documenting Sinatra routes for extensions (Yard::Sinatra doesn't work)

I am writing a moderate-sized Sinatr开发者_JAVA百科a app that I break into extensions, placed in ./lib/extensions/. I want to document each route, but Yard::Sinatra only documents the routes defined in the main application.rb file. Can I configure Yard::Sinatra to do something or do I have to write my own plugin?

You might want to take a look into Cachafla's YARD::Sinatra version of the gem: gem install cachafla-yard-sinatra
