RubySonar is a type inferencer and indexer for Ruby, which does sophisticated interprocedural analysis to infer types. It is one of the underlying technologies that powers the code search site Sourcegraph.
RubySonar is modeled after PySonar2, which does a similar analysis for Python and has been in use by Sourcegraph and Google. To understand its technical properties, please refer to my blog posts:

mvn package
- irb
RubySonar uses the irb interpreter to parse Ruby code, so please make sure you
have it installed and pointed to by the PATH environment variable.
RubySonar is mainly designed as a library for IDEs and other developer tools, so its interface may not be as appealing as an end-user tool, but for your understanding of the library's capabilities, a reasonably nice demo program has been built.
You can build a simple "code-browser" of your ruby code with the following command line:
java -jar target/rubysonar-0.1-SNAPSHOT.jar /path/to/project ./html
This will take a few minutes. You should find some interactive HTML files inside the html directory after this process.
