Open Source Ruby Source Code Analysis Tools for Linux

AdLint is a source code static analyzer. It can point out insecure or nonportable code fragments, and can measure various quality metrics of the source code. It (currently) can analyze source code compliant with ANSI C89 / ISO C90 and partly ISO C99. AdLint is written in Ruby. So, it is available for Windows, Mac OS X, GNU/Linux, FreeBSD and any other platforms supported by Ruby.

AdLint Goodies is a collection of miscellaneous utilities for AdLint. All goodies are written in Ruby and available for Windows, Mac OS X, GNU/Linux, FreeBSD and any other platforms supported by Ruby.

Code coverage for Ruby with a powerful configuration library and automatic merging of coverage across test suites. SimpleCov is a code coverage analysis tool for Ruby. It uses Ruby's built-in Coverage library to gather code coverage data, but makes processing its results much easier by providing a clean API to filter, group, merge, format, and display those results, giving you a complete code coverage suite that can be set up with just a couple lines of code. SimpleCov/Coverage track covered ruby code, gathering coverage for common templating solutions like erb, slim and haml is not supported. In most cases, you'll want overall coverage results for your projects, including all types of tests, Cucumber features, etc. SimpleCov automatically takes care of this by caching and merging results when generating reports, so your report actually includes coverage across your test suites and thereby gives you a better picture of blank spots.
