@scottbarrow This bug is fixed in #36, and will be available in next release. In a mean time, you can use jard from master branch, or that specific commit:

gem 'ruby_jard', group: :development, git: 'https://github.com/nguyenquangminh0711/ruby_jard'
# or
gem 'ruby_jard', group: :development, git: 'https://github.com/nguyenquangminh0711/ruby_jard', ref: '13455f2813f8820e0be502552cbf6fd312b4a396'

I'll close this issue when a new version is released. Many thanks for your report ❤️
