This is very much the definition of a code dump: a single file, not following any standard ruby code conventions - not even naming conventions (it would be called "rx" otherwise), tests within that file, misformatted code. snake_cased and camedBacked variables mixed. It monkey-patches Enumerable and uses class variables. `gets` at the end of the file, to keep the Windows console open, rendering the whole thing unusable as a library. Also, the author clearly doesn't know that you don't need ".rb" when requiring files. Last commit on December 22, 2012.<p>Could people please have a look at the source before posting stuff here? This is not a project to be taken seriously and a waste of time. "Someone at Microsoft was playing with Ruby" is the only valuable thing you can get out of it.
